Alexander Gram Bell

Alexander Graham Bell

Alexander Graham Bell was born in 1847. As a child He took after his grandfather who was an actor who entertained people with his voice. Alexanders mother, who was deaf, would have people talk to her through her ear tube, which amplifies speech by talking through a object that looked like a horn. Alexander choose to talk to his mother by speaking in low tones very close to her forehead. Alexander thought that his mother would be able to "hear" him by the vibrations his voice put on her forehead. Alexander at about the age of 14 and his brother, Melville, created a contraption that had a fake mouth, tongue, and lungs that you could force air out of. This contraption could make human-like sounds. After this Alexander manipulated his dogs vocal cords and mouth to change growls to words. By the time Alexander was sixteen he was teaching music at a boys boarding school.

Alexander Bell meet Thomas Watson at an electrical machine shop, Watson and Alexander formed a friendship after Alexander told him of his idea about transmitting speech over a wire. On June 2,1875, when working in the transmitting room Watson produced a twang when trying to loosen up a wire. Alexander working on the transmitter was able to send sounds that resembled that of a human voice. Next, Alexander discovered that a wire vibrated by speech when placed in a conducting liquid, like mercury and would produce a current. Basically speech could be transmitted by wire. On March 10,1876 Alexander and Watson were working on the machine when Alexander knocked over battery acid. He shouted, "Mr. Watson, come here. I need you!" and Watson working in the receiver room heard his voice coming through the wire.

Later, the Bell Company was formed, which is now AT&T. Before Alexander died in 1922, he had invented an electric probe for locating metal objects in bodies, and the artificial respirator.

A skillful inventor and generous philanthropist, he astounded the world with his intuitive ideas that proved to be both innovative and extremely practical in the latter half of the 19th century. Most notable, of course, are Bell's work in developing the telephone and his venerable life-long endeavor to educate the deaf. Originally, his only wish was to help deaf people overcome their difficulty in learning verbal communication, and later was pushed into researching the possibility of a device that could transmit the human voice electronically over a distance. After building his first working telephone model, Bell's fame spread quickly as people in America and around the world began to realize the awesome potential this wonderfully fascinating new device held in store for society (Brinkley 481). His telephone an instant success and already a burgeoning industry, A. G. Bell decided to turn his attention back to assisting the deaf and following other creative ideas including the development of a metal detector, an electric probe which was used by many surgeons before the X ray was invented, a device having the same purpose as today's iron lung, and also a method of locating icebergs by detecting echoes from them. With his many inventions (especially the insanely popular and universally applied telephone), his efforts to educate the deaf, and the founding and financing of the American Association to Promote the Teaching of Speech to the Deaf (now called the Alexander Graham Bell Association for the Deaf), Alexander Graham Bell has become a very important historical figure indeed (Berstein 9). Perhaps a key factor in Bell's successful life was his invigorating background. His family and his education definitely had a deep influence on his career. Born in Scotland, his mother was a painter and an accomplished musician, his father a teacher of the deaf and speech textbook writer. His father invented "Visible Speech," a code of symbols which indicated the position of the throat, tongue, and lips in making sounds. These symbols helped guide the deaf in learning to speak. His grandfather, also named Alexander Bell, had similarly specialized in good speech. He acted for several years and later gave dramatic readings from Shakespeare. Young Alexander Graham Bell had a great talent for music. He played by ear from infancy, and received a musical education. Later, Bell and his two brothers assisted their father in public demonstrations in Visible Speech, beginning in 1862. He also enrolled as a student-teacher at Weston House, a boys' school, where he taught music and speech in exchange for instructions in other subjects. Bell became a full-time teacher after studying for a year at the University of Edinburgh. He also studied at the University of London and used Visible Speech to teach a class of deaf children. Growing up in a healthy environment where creativity and new ideas were embraced with vigor was to certainly contribute to Alexander Graham Bell's genius later on in life (Winefield 12). Young Bell carried out in 1866 a series of experiments to determine how vowel sounds are produced. A book, describing experiments in combing the notes of electrically driven tuning forks to make vowel sounds, gave him the idea of "telegraphing" speech, though he had no idea about doing it. However, this was the start of his interest in electricity. Bell took charge of his father's work while the latter lectured in America in 1968. Bell became his father's partner in London in the following year. He specialized in the anatomy of the vocal apparatus at University College in London at the same time. In 1872, Alexander opened his own school for teachers of the deaf in Boston. The following year, he became a professor at Boston University. Bell won the friendship of Gardiner Green Hubbard, a Boston attorney at this time. Hubbard's daughter, Mabel, had been left deaf by scarlet fever when she was 4. Hubbard had Bell tutor her and in no time they were in love, although Mabel's first memories of Alexander were not all positive. I both did not, and did like him. He was so interesting that I was forced to like to listen to him, but he himself I disliked. He dressed carelessly and in a horrible, shiny [hat]—expensive but fashionable—and which made his jet-black hair look shiny. Altogether I did not think him exactly a gentleman (Winefield 17). Miss Hubbard became Bell's wife in 1877. Another friendship developed when Thomas Sanders, a successful merchant, brought his son to Bell as a private pupil. Both Hubbard and Sanders learned in 1873 of electrical experiments Bell carried on at night and offered to pay the cost. Bell did not attempt to transmit speech electrically at this time. He tried instead to send several telegraph messages over a single wire at the same time. �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������y��ˆ��ý�������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������^J����������[��©��ò��@����á��2��ƒ��Ï����j��º��

Albert Einstein 3

Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose
name is known by almost all living people. While most of these do not understand this man's
work, everyone knows that its impact on the world of science is astonishing. Yes, many
have heard of Albert Einstein's General Theory of relativity, but few know about the
intriguing life that led this scientist to discover what some have called, "The greatest single
achievement of human thought."

Einstein was born in Ulm, Germany on March 14, 1874. Before his first birthday, his family
had moved to Munich where young Albert's father, Hermann Einstein, and uncle set up a
small electro-chemical business. He was fortunate to have an excellent family with which he
held a strong relationship. Albert's mother, Pauline Einstein, had an intense passion for music
and literature, and it was she that first introduced her son to the violin in which he found
much joy and relaxation. Also, he was very close with his younger sister, Maja, and they
could often be found in the lakes that were scattered about the countryside near Munich.

As a child, Einstein's sense of curiosity had already begun to stir. A favorite toy of his was
his father's compass, and he often marvelled at his uncle's explanations of algebra. Although
young Albert was intrigued by certain mysteries of science, he was considered a slow
learner. His failure to become fluent in German until the age of nine even led some teachers
to believe he was disabled.

Einstein's post-basic education began at the Luitpold Gymnasium when he was ten. It was
here that he first encountered the German spirit through the school's strict disciplinary policy.
His disapproval of this method of teaching led to his reputation as a rebel. It was probably
these differences that caused Einstein to search for knowledge at home. He began not with
science, but with religion. He avidly studied the Bible seeking truth, but this religious fervor
soon died down when he discovered the intrigue of science and math. To him, these seemed
much more realistic than ancient stories. With this new knowledge he disliked class even
more, and was eventually expelled from Luitpold Gymnasium being considered a disruptive
influence.

Feeling that he could no longer deal with the German mentality, Einstein moved to
Switzerland where he continued his education. At sixteen he attempted to enroll at the
Federal Institute of Technology but failed the entrance exam. This forced him to study locally
for one year until he finally passed the school's evaluation. The Institute allowed Einstein to
meet many other students that shared his curiosity, and It was here that his studies turned
mainly to Physics. He quickly learned that while physicists had generally agreed on major
principals in the past, there were modern scientists who were attempting to disprove
outdated theories. Since most of Einstein's teachers ignored these new ideas, he was again
forced to explore on his own. In 1900 he graduated from the Institute and then achieved
citizenship to Switzerland.

Einstein became a clerk at the Swiss Patent Office in 1902. This job had little to do with
physics, but he was able to satiate his curiosity by figuring out how new inventions worked.
The most important part of Einstein's occupation was that it allowed him enough time to
pursue his own line of research. As his ideas began to develop, he published them in
specialist journals. Though he was still unknown to the scientific world, he began to attract a
large circle of friends and admirers. A group of students that he tutored quickly transformed
into a social club that shared a love of nature, music, and of course, science. In 1903 he
married Mileva Meric, a mathematician friend.

In 1905, Einstein published five separate papers in a journal, the Annals of Physics. The first
was immediately acknowledged, and the University of Zurich awarded Einstein an additional
degree. The other papers helped to develop modern physics and earned him the reputation
of an artist. Many scientists have said that Einstein's work contained an imaginative spirit that
was seen in most poetry. His work at this time dealt with molecules, and how their motion
affected temperature, but he is most well known for his Special Theory of Relativity which
tackled motion and the speed of light. Perhaps the most important part of his discoveries
was the equation: E= mc2.

After publishing these theories Einstein was promoted at his office. He remained at the
Patents Office for another two years, but his name was becoming too big among the
scientific community. In 1908, Einstein began teaching party time at the University of Berne,
and the following year, at the age of thirty, he became employed full time by Zurich
University. Einstein was now able to move to Prague with his wife and two sons, Hans
Albert and Eduard. Finally, after being promoted to a professor, Einstein and his family were
able to enjoy a good standard of living, but the job's main advantage was that it allowed
Einstein to access an enormous library. It was here that he extended his theory and
discussed it with the leading scientists of Europe. In 1912 he chose to accept a job placing
him in high authority at the Federal Institute of Technology, where he had originally studied.
It was not until 1914 that Einstein was tempted to return to Germany to become research
director of the Kaiser Wilhelm Institute for Physics.

World War I had a strong effect on Einstein. While the rest of Germany supported the army,
he felt the war was unnecessary, and disgusting. The new weapons of war which attempted
to mass slaughter people caused him to devote much of his life toward creating peace.
Toward the end of the war Einstein joined a political party that worked to end the war, and
return peace to Europe. In 1916 this party was outlawed by the government, and Einstein
was seen as a traitor.

In that same year, Einstein published his General Theory of relativity, This result of ten years
work revolutionized physics. It basically stated that the universe had to be thought of as
curved, and told how light was affected by this. The next year, Einstein published another
paper that added that the universe had no boundary, but actually twisted back on its self.

After the war, many aspects of Einstein's life changed. He divorced his wife, who had been
living in Zurich with the children throughout the war, and married his cousin Elsa Lowenthal.
This led to a renewed interest in his Jewish roots, and he became an active supporter of
Zionism. Since anti-Semitism was growing in Germany, he quickly became the target of
prejudice. There were many rumors about groups who were trying to kill Einstein, and he
began to travel extensively. The biggest change, though, was in 1919 when scientist who
studied an eclipse confirmed that his theories were correct.

In 1921, he traveled through Britain and the United States raising funds for Zionism and
lecturing about his theories. He also visited the battle sites of the war, and urged that Europe
renew scientific and cultural links. He promoted non-patriotic, non-competitive education,
believing that it would prevent war from happening in the future. He also believed that
socialism would help the world achieve peace.

Einstein received the Nobel Prize for Physics in 1922. He gave all the money to his ex-wife
and children to help with their lives and education. After another lecture tour, he visited
Palestine for the opening the Hebrew University in Jerusalem. He also talked about the
possibilities that Palestine held for the Jewish people. Upon his return he began to enjoy a
calmer life in which he returned to his original curiosity, religion.

While Einstein was visiting America in 1933 the Nazi party came to power in Germany.
Again he was subject to anti-Semitic attacks, but this time his house was broken into, and he
was publicly considered an enemy of the nation. It was obvious that he could not return to
Germany, and for the second time he renounced his German citizenship. During these early
years in America he did some research at Princeton, but did not accomplish much of
significance.

In 1939 the second World War began to take form. There was heated argument during this
time over whether the United States should explore the idea of an atomic bomb. Einstein
wrote to President Roosevelt warning him of the disaster that could occur if the Nazi's
developed it first. Einstein did not participate in the development of the bomb, but the idea
did stem from his equation E=mc2. Just as he knew that the bomb was under development,
he also knew when it was going to be used. Just before the bomb was dropped on Japan
Einstein wrote a letter to the President begging him not to use this terrible weapon.

The rest of Einstein's life was dedicated to promoting peace. After the war ended, he
declared, "The war is won, but the peace is not." He wrote many articles and made many
speeches calling for a world government. His fame, at this point, was legendary. People from
all over would write to him for advice, and he would often answer them. He also continued
his scientific research until the day he died. This was on April 18, 1955. There is no doubt
that he was dissatisfied that he never was able to find the true meaning of existence that he
strove for all his life.

Werner Heisenberg

Werner Heisenberg

One cannot fully appreciate the work of Werner Heisenberg unless one examines his contributions in the context of the time in which he lived. Werner Karl Heisenberg was born in Wuerzburg, Germany, on December 5, 1901, and grew up in academic surroundings, in a household devoted to the humanities. His father was a professor at the University of Munich and undoubtedly greatly influenced young Werner, who was a student at the Maximilian Gymnasium.
Heisenberg had the opportunity to work with many of the top physicists in the world including Niels Bohr and Max Born. Like many of the top physicists of the time Heisenberg received his doctorate at an early age. In Heisenberg's case he received it at the young age of twenty three. Heisenberg was not just a researcher. He was also a professor and author. During his career he taught at many prestigious universities, including the Universities of Leipzig, Goettingen, and Berlin. He also wrote many important books including, Physical Principles of the Quantum Theory, Cosmic Radiation, Physics and Philosophy, and Introduction to the Unified Theory of Elementary Particles. In 1932 he won the Nobel Prize in Physics for his work in Quantum Mechanics.
With the Nazi's in power, and World War two on the horizon it was inevitable that his German heritage would play a crucial role in his career. Before Germany's blitzkrieg on Poland Heisenberg decided to make one final visit of his friends in the West. Many tried to convince him to stay and accept a professorship at Columbia, but Heisenberg declined. He felt that it was his duty to preserve the foundation of science in Germany during the war. He also believed that by staying in Germany during the war, he could help individual German scientists. In fact, he did offer jobs to Jewish scientists when they were fired from their posts at other universities. As time passed, Heisenberg found that he was powerless to protect his friends. Heisenberg himself was personally attacked, and his appointment at the University of Munich was blocked. For over a year Heisenberg was attacked in the SS newspaper, which referred to him as a "white Jew." The attack became so threatening that Heisenberg's mother, who had a slight connection to Himmler's family, wrote to Himmler's mother asking Himmler to intercede. Himmler personally cleared Heisenberg of the charges leveled against him a year later, but he was told to study science and avoid discussing scientists. The strain of the investigation surely affected Heisenberg's creativity.
During the war Heisenberg worked on the German A-bomb project along with a number of other German scientists. It has been proposed in the novel Heisenberg's War, written by Thomas Powers, that Heisenberg deliberately sabotaged this project to keep the bomb out of Hitler's hands. After the war was over, all of the scientists in Germany working on the A-bomb project, including Heisenberg, were interned in England to be questioned about their work on the project.
Heisenbergs nationalism eventually ruined many of his academic friendships. His close relationship with Neils Bohr was destroyed by his decision to remain in Germany during the war. His failure to be more specific about his stand in whether or not to seriously work to develop a German bomb played an important part in his inability to reestablish ties with friends who moved to the West. The creative interaction with many leading scientists prior to the war was not resumed at the war's end.
Heisenberg's most important finding, the Uncertainty Principle is the corner stone of Quantum Mechanics. However, many advances in Quantum Mechanics had to be made before Heisenberg found it. Everything started with Rutherford's model of the atom. Consisting of a positively charged central nucleus, surrounded by orbiting planetary electrons. Around the same time that Rutherford was discovering the basic structure of the atom, Plank did some important work also. Finding that energy from an oscillating particle is emitted not continuously, but in packets of energy he developed the Quantum Theory of Radiation. From this came the universal constant h which played a large role in Heisenbergs uncertainty principle. Neils Bohr then made a new model of the atom, which combined both Rutherford's and Plank's work. This new model accounted for known patterns of atomic radiation as seen in spectra. However, what Bohr wrote on paper about the electron activity and what other physicists were observing were two different things. Bohr had developed his quantum theory of the atom by discarding the idea of a classical frequency associated with the orbit of an electron, but he still retained the concept of the classical orbit. Heisenberg went one step further and discarded the concept of the orbit itself. Rather than the classical idea of the position and the motion, or momentum, of the electron at each instant in time, Heisenberg introduced his square arrays or matrices, which depict the electron as existing simultaneously in all possible Bohr orbits. After Heisenberg's discovery, the classical concept of the electron as a particle was no longer justifiable.
Heisenberg was led to these revolutionary ideas by his insistence on utilizing only those quantities in a theory that are directly observable. Since the orbit of an electron is not observable, it can have no place in a theory. Only the spectral lines are observed, and, since these involve pairs of orbits, all quantities that are used to describe the electron inside the atom should be associated with such pairs.
Such thinking led to Heisenberg's matrices. One of the important features of matrices is that it is not commutative. If the array representing the position of an electron is q and an array representing its momentum is p, then the product pq is not the same as the product qp.
This showed Heisenberg that the uncertainty relationship is purely an algebraic consequence of his matrix theory. If you picture the product pq as representing a measurement of the position of the electron followed by a measurement of its momentum; qp, on the other hand, represents the measurement of the momentum of a particle followed by at the measurement of its position. That these two sets of measurements give different results simply means that the measurement of the momentum of a particle destroys our knowledge of its position, and vice versa. It follows that it is impossible to obtain or to have precise knowledge of the position and the momentum of a particle simultaneously; this is the essence of the uncertainty principle.
Its significance for the structure of the atom is that we have no way of determining the orbit of an electron inside the atom observationally. As Heisenberg pointed out in his analysis of the Copenhagen interpretation of quantum theory, an electron can be observed inside an atom only with a gamma-ray microscope which, because of the short wavelength of gamma rays, has a high resolving power. This microscope shows us where the electron is at any moment, but at least one gamma-ray photon must be reflected from the electron. In this very process the electron is knocked out of the atom. It is senseless then to speak of its orbit.
Although the uncertainty relations can be derived mathematically from theory, it is much more instructive to derive them from the physical picture. This method shows clearly the interrelationship between the wave and the particle. In fact, it is clear from Heisenberg's analysis that wave and particle are complementary aspects, as are position and momentum. It was from considerations such as these that Bohr developed his theory of complementarily, which is essential for an understanding of modern atomic theories.
The uncertainty relations completely change our ideas of causality. If we cannot determine the position and the momentum of a particle simultaneously to any desired degree of accuracy, we cannot determine its future course. We can solve equations for the motion of the particle. However, these solutions can tell us its future history only if at some moment in the past or at the present instant we know its position and momentum. The farther we try to look into the future, the less accurate our predictions become because our present uncertainty, however small leads to greater deviations from the predicted pattern of the motion as the time increases. We can understand this situation by considering the lunar missile probes carried out by the United States and Soviet Union. To hit a target as gar away as the moon involves extreme accuracy in aiming the rocket and giving it the correct initial momentum; if we wish to hit targets at greater distances, our accuracy will have to be increased considerably because the further the distance, the greater the multiplication of any initial error.
Today we use the term quantum mechanics for the entire mathematical scheme that is used to treat problems in atomic, nuclear, elementary-particle, and field physics. The mathematics of quantum mechanics stems directly from Heisenberg's matrix mechanics and is a consequence of his uncertainty principle. If anyone were to prove his uncertainty principle wrong the foundations of quantum mechanics would fall.
Heisenberg spent the final years of his career trying to derive the properties of such elementary particles as electrons, protons, and so on, from a departure from quantum field theory by having the field itself construct its own particles. Unfortunately, this approach led to a very complex mathematical formulation which some say spoiled the great beauty of quantum mechanics.

The Significance of Alexander Graham Bell in American History

Alexander Graham Bell is a name of great significance in American history today. A skillful inventor and generous philanthropist, he astounded the world with his intuitive ideas that proved to be both innovative and extremely practical in the latter half of the 19th century. Most notable, of course, are Bell's work in developing the telephone and his venerable life-long endeavor to educate the deaf. Originally, his only wish was to help deaf people overcome their difficulty in learning verbal communication, and later was pushed into researching the possibility of a device that could transmit the human voice electronically over a distance. After building his first working telephone model, Bell's fame spread quickly as people in America and around the world began to realize the awesome potential this wonderfully fascinating new device held in store for society (Brinkley 481). His telephone an instant success and already a burgeoning industry, A. G. Bell decided to turn his attention back to assisting the deaf and following other creative ideas including the development of a metal detector, an electric probe which was used by many surgeons before the X ray was invented, a device having the same purpose as today's iron lung, and also a method of locating icebergs by detecting echoes from them. With his many inventions (especially the insanely popular and universally applied telephone), his efforts to educate the deaf, and the founding and financing of the American Association to Promote the Teaching of Speech to the Deaf (now called the Alexander Graham Bell Association for the Deaf), Alexander Graham Bell has become a very important historical figure indeed (Berstein 9).
Perhaps a key factor in Bell's successful life was his invigorating background. His family and his education definitely had a deep influence on his career. Born in Scotland, his mother was a painter and an accomplished musician, his father a teacher of the deaf and speech textbook writer. His father invented "Visible Speech," a code of symbols which indicated the position of the throat, tongue, and lips in making sounds. These symbols helped guide the deaf in learning to speak. His grandfather, also named Alexander Bell, had similarly specialized in good speech. He acted for several years and later gave dramatic readings from Shakespeare. Young Alexander Graham Bell had a great talent for music. He played by ear from infancy, and received a musical education. Later, Bell and his two brothers assisted their father in public demonstrations in Visible Speech, beginning in 1862. He also enrolled as a student-teacher at Weston House, a boys' school, where he taught music and speech in exchange for instructions in other subjects. Bell became a full-time teacher after studying for a year at the University of Edinburgh. He also studied at the University of London and used Visible Speech to teach a class of deaf children. Growing up in a healthy environment where creativity and new ideas were embraced with vigor was to certainly contribute to Alexander Graham Bell's genius later on in life (Winefield 12).
Young Bell carried out in 1866 a series of experiments to determine how vowel sounds are produced. A book, describing experiments in combing the notes of electrically driven tuning forks to make vowel sounds, gave him the idea of "telegraphing" speech, though he had no idea about doing it. However, this was the start of his interest in electricity.
Bell took charge of his father's work while the latter lectured in America in 1968. Bell became his father's partner in London in the following year. He specialized in the anatomy of the vocal apparatus at University College in London at the same time. In 1872, Alexander opened his own school for teachers of the deaf in Boston. The following year, he became a professor at Boston University.
Bell won the friendship of Gardiner Green Hubbard, a Boston attorney at this time. Hubbard's daughter, Mabel, had been left deaf by scarlet fever when she was 4. Hubbard had Bell tutor her and in no time they were in love, although Mabel's first memories of Alexander were not all positive.
I both did not, and did like him. He was so interesting that I was forced to like to listen to him, but he himself I disliked. He dressed carelessly and in a horrible, shiny [hat]-expensive but fashionable-and which made his jet-black hair look shiny. Altogether I did not think him exactly a gentleman (Winefield 17).
Miss Hubbard became Bell's wife in 1877. Another friendship developed when Thomas Sanders, a successful merchant, brought his son to Bell as a private pupil. Both Hubbard and Sanders learned in 1873 of electrical experiments Bell carried on at night and offered to pay the cost.
Bell did not attempt to transmit speech electrically at this time. He tried instead to send several telegraph messages over a single wire at the same time. In 1874, while visiting his father in B

Albert Einstein

ALBERT EINSTEIN


Albert Einstein was born in Germany on March 14, 1879.As
a kid he had trouble learning to speak. His parents thought that
he might be mentally retarded. He was not smart in school. He
suffered under the learning methods that they used in the
schools of Germany at that time so he was never able to finish
his studies. In 1894 his father's business had failed and the
family moved to Milan, Italy. Einstein who had grown interested
in science, went to Zurich, Switzerland, to enter a famous
technical school. There his ability in mathematics and physics
began to show.
When Einstein was graduated in 1900 he was unable to get a
teaching appointment at a university. Instead he got a clerical
job in the patent office at Bern, Switzerland. It was not what
he wanted but it would give him leisure for studying and
thinking. While over there he wrote scientific papers. Einstein
submitted one of his scientific papers to the University of Zurich
to obtain a Ph.D. degree in 1905. In 1908 he sent a second
paper to the University of Bern and became lecturer there. The
next year Einstein received a regular appointment as associate
professor of physics at the University of Zurich. By 1909,
Einstein was recognized throughout Europe as a leading
scientific thinker. In 1909 the fame that resulted from his
theories got Einstein a job at the University of Prague, and in
1913 he was appointed director of a new research institution
opened in Berlin, the Kaiser Wilhelm Physics Institute.
In 1915, during World War 1, Einstein published a paper
that extended his theories. He put forth new views on the
nature of gravitation. Newton's theories he said were not
accurate enough. Einstein's theories seemed to explain the slow
rotation of the entire orbit of the planet Mercury, which
Newton's theories did not explain. Einstein's theories also
predicted that light rays passing near the sun would be bent out
of a straight line. When this was verified at the eclipse of 1919,
Einstein was instantly accepted as the great scientific thinker
since Newton.
By now Germany had fallen in the hands of Adolf Hitler and
his Nazis. Albert Einstein was Jewish. In 1933 when the Nazis
came to power, Einstein happened to be in California. He did
not return to Germany. He went to Belgium instead. The Nazis
confiscated his possessions, publicly burned his writings, and
expelled him from all German scientific societies. Einstein came
back to the United States and became a citizen.
The atomic bomb is an explosive device that depends upon
the release of energy in a nuclear reaction known as FISSION,
which is the splitting of atomic nuclei. Einstein sent a letter to
President Franklin D. Roosevelt, pointing out that atomic bombs
are possible and that enemy nations must be allowed to make
them first.
Roosevelt agreed with Einstein and funded the Manhattan
Project.
On April 18, 1955, Albert Einstein died. To his dying day,
he urged the world to come to some agreement that would
make nuclear wars forever impossible.

Albert Einstein 5

Of all the scientists to emerge from the nineteenth and twentieth centuries there is one
whose name is known by almost all living people. While most of these do not understand
this man's work, everyone knows that its impact on the world of science is astonishing. Yes,
many have heard of Albert Einstein's General Theory of relativity, but few know about the
intriguing life that led this scientist to discover what some have called, "The greatest single
achievement of human thought."

Einstein was born in Ulm, Germany on March 14, 1874. Before his first birthday, his family
had moved to Munich where young Albert's father, Hermann Einstein, and uncle set up a
small electro-chemical business. He was fortunate to have an excellent family with which he
held a strong relationship. Albert's mother, Pauline Einstein, had an intense passion for
music and literature, and it was she that first introduced her son to the violin in which he
found much joy and relaxation. Also, he was very close with his younger sister, Maja, and
they could often be found in the lakes that were scattered about the countryside near
Munich.

As a child, Einstein's sense of curiosity had already begun to stir. A favorite toy of his was
his father's compass, and he often marvelled at his uncle's explanations of algebra. Although
young Albert was intrigued by certain mysteries of science, he was considered a slow
learner. His failure to become fluent in German until the age of nine even led some teachers
to believe he was disabled.

Einstein's post-basic education began at the Luitpold Gymnasium when he was ten. It was
here that he first encountered the German spirit through the school's strict disciplinary
policy. His disapproval of this method of teaching led to his reputation as a rebel. It was
probably these differences that caused Einstein to search for knowledge at home. He began
not with science, but with religion. He avidly studied the Bible seeking truth, but this
religious fervor soon died down when he discovered the intrigue of science and math. To
him, these seemed much more realistic than ancient stories. With this new knowledge he
disliked class even more, and was eventually expelled from Luitpold Gymnasium being
considered a disruptive influence.

Feeling that he could no longer deal with the German mentality, Einstein moved to
Switzerland where he continued his education. At sixteen he attempted to enroll at the
Federal Institute of Technology but failed the entrance exam. This forced him to study
locally for one year until he finally passed the school's evaluation. The Institute allowed
Einstein to meet many other students that shared his curiosity, and It was here that his
studies turned mainly to Physics. He quickly learned that while physicists had generally
agreed on major principals in the past, there were modern scientists who were attempting to
disprove outdated theories. Since most of Einstein's teachers ignored these new ideas, he
was again forced to explore on his own. In 1900 he graduated from the Institute and then
achieved citizenship to Switzerland.

Einstein became a clerk at the Swiss Patent Office in 1902. This job had little to do with
physics, but he was able to satiate his curiosity by figuring out how new inventions worked.
The most important part of Einstein's occupation was that it allowed him enough time to
pursue his own line of research. As his ideas began to develop, he published them in
specialist journals. Though he was still unknown to the scientific world, he began to attract a
large circle of friends and admirers. A group of students that he tutored quickly transformed
into a social club that shared a love of nature, music, and of course, science. In 1903 he
married Mileva Meric, a mathematician friend.

In 1905, Einstein published five separate papers in a journal, the Annals of Physics. The
first was immediately acknowledged, and the University of Zurich awarded Einstein an
additional degree. The other papers helped to develop modern physics and earned him the
reputation of an artist. Many scientists have said that Einstein's work contained an
imaginative spirit that was seen in most poetry. His work at this time dealt with molecules,
and how their motion affected temperature, but he is most well known for his Special
Theory of Relativity which tackled motion and the speed of light. Perhaps the most
important part of his discoveries was the equation: E= mc2.

After publishing these theories Einstein was promoted at his office. He remained at the
Patents Office for another two years, but his name was becoming too big among the
scientific community. In 1908, Einstein began teaching party time at the University of Berne,
and the following year, at the age of thirty, he became employed full time by Zurich
University. Einstein was now able to move to Prague with his wife and two sons, Hans
Albert and Eduard. Finally, after being promoted to a professor, Einstein and his family
were able to enjoy a good standard of living, but the job's main advantage was that it
allowed Einstein to access an enormous library. It was here that he extended his theory and
discussed it with the leading scientists of Europe. In 1912 he chose to accept a job placing
him in high authority at the Federal Institute of Technology, where he had originally studied.
It was not until 1914 that Einstein was tempted to return to Germany to become research
director of the Kaiser Wilhelm Institute for Physics.

World War I had a strong effect on Einstein. While the rest of Germany supported the
army, he felt the war was unnecessary, and disgusting. The new weapons of war which
attempted to mass slaughter people caused him to devote much of his life toward creating
peace. Toward the end of the war Einstein joined a political party that worked to end the
war, and return peace to Europe. In 1916 this party was outlawed by the government, and
Einstein was seen as a traitor.

In that same year, Einstein published his General Theory of relativity, This result of ten years
work revolutionized physics. It basically stated that the universe had to be thought of as
curved, and told how light was affected by this. The next year, Einstein published another
paper that added that the universe had no boundary, but actually twisted back on its self.

After the war, many aspects of Einstein's life changed. He divorced his wife, who had been
living in Zurich with the children throughout the war, and married his cousin Elsa Lowenthal.
This led to a renewed interest in his Jewish roots, and he became an active supporter of
Zionism. Since anti-Semitism was growing in Germany, he quickly became the target of
prejudice. There were many rumors about groups who were trying to kill Einstein, and he
began to travel extensively. The biggest change, though, was in 1919 when scientist who
studied an eclipse confirmed that his theories were correct.

In 1921, he traveled through Britain and the United States raising funds for Zionism and
lecturing about his theories. He also visited the battle sites of the war, and urged that
Europe renew scientific and cultural links. He promoted non-patriotic, non-competitive
education, believing that it would prevent war from happening in the future. He also
believed that socialism would help the world achieve peace.

Einstein received the Nobel Prize for Physics in 1922. He gave all the money to his ex-wife
and children to help with their lives and education. After another lecture tour, he visited
Palestine for the opening the Hebrew University in Jerusalem. He also talked about the
possibilities that Palestine held for the Jewish people. Upon his return he began to enjoy a
calmer life in which he returned to his original curiosity, religion.

While Einstein was visiting America in 1933 the Nazi party came to power in Germany.
Again he was subject to anti-Semitic attacks, but this time his house was broken into, and
he was publicly considered an enemy of the nation. It was obvious that he could not return
to Germany, and for the second time he renounced his German citizenship. During these
early years in America he did some research at Princeton, but did not accomplish much of
significance.

In 1939 the second World War began to take form. There was heated argument during this
time over whether the United States should explore the idea of an atomic bomb. Einstein
wrote to President Roosevelt warning him of the disaster that could occur if the Nazi's
developed it first. Einstein did not participate in the development of the bomb, but the idea
did stem from his equation E=mc2. Just as he knew that the bomb was under development,
he also knew when it was going to be used. Just before the bomb was dropped on Japan
Einstein wrote a letter to the President begging him not to use this terrible weapon.

The rest of Einstein's life was dedicated to promoting peace. After the war ended, he
declared, "The war is won, but the peace is not." He wrote many articles and made many
speeches calling for a world government. His fame, at this point, was legendary. People
from all over would write to him for advice, and he would often answer them. He also
continued his scientific research until the day he died. This was on April 18, 1955. There is
no doubt that he was dissatisfied that he never was able to find the true meaning of
existence that he strove for all his life.

Albert Einstein 3 4

Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose
name is known by almost all living people. While most of these do not understand this man's
work, everyone knows that its impact on the world of science is astonishing. Yes, many
have heard of Albert Einstein's General Theory of relativity, but few know about the
intriguing life that led this scientist to discover what some have called, "The greatest single
achievement of human thought."

Einstein was born in Ulm, Germany on March 14, 1874. Before his first birthday, his family
had moved to Munich where young Albert's father, Hermann Einstein, and uncle set up a
small electro-chemical business. He was fortunate to have an excellent family with which he
held a strong relationship. Albert's mother, Pauline Einstein, had an intense passion for music
and literature, and it was she that first introduced her son to the violin in which he found
much joy and relaxation. Also, he was very close with his younger sister, Maja, and they
could often be found in the lakes that were scattered about the countryside near Munich.

As a child, Einstein's sense of curiosity had already begun to stir. A favorite toy of his was
his father's compass, and he often marvelled at his uncle's explanations of algebra. Although
young Albert was intrigued by certain mysteries of science, he was considered a slow
learner. His failure to become fluent in German until the age of nine even led some teachers
to believe he was disabled.

Einstein's post-basic education began at the Luitpold Gymnasium when he was ten. It was
here that he first encountered the German spirit through the school's strict disciplinary policy.
His disapproval of this method of teaching led to his reputation as a rebel. It was probably
these differences that caused Einstein to search for knowledge at home. He began not with
science, but with religion. He avidly studied the Bible seeking truth, but this religious fervor
soon died down when he discovered the intrigue of science and math. To him, these seemed
much more realistic than ancient stories. With this new knowledge he disliked class even
more, and was eventually expelled from Luitpold Gymnasium being considered a disruptive
influence.

Feeling that he could no longer deal with the German mentality, Einstein moved to
Switzerland where he continued his education. At sixteen he attempted to enroll at the
Federal Institute of Technology but failed the entrance exam. This forced him to study locally
for one year until he finally passed the school's evaluation. The Institute allowed Einstein to
meet many other students that shared his curiosity, and It was here that his studies turned
mainly to Physics. He quickly learned that while physicists had generally agreed on major
principals in the past, there were modern scientists who were attempting to disprove
outdated theories. Since most of Einstein's teachers ignored these new ideas, he was again
forced to explore on his own. In 1900 he graduated from the Institute and then achieved
citizenship to Switzerland.

Einstein became a clerk at the Swiss Patent Office in 1902. This job had little to do with
physics, but he was able to satiate his curiosity by figuring out how new inventions worked.
The most important part of Einstein's occupation was that it allowed him enough time to
pursue his own line of research. As his ideas began to develop, he published them in
specialist journals. Though he was still unknown to the scientific world, he began to attract a
large circle of friends and admirers. A group of students that he tutored quickly transformed
into a social club that shared a love of nature, music, and of course, science. In 1903 he
married Mileva Meric, a mathematician friend.

In 1905, Einstein published five separate papers in a journal, the Annals of Physics. The first
was immediately acknowledged, and the University of Zurich awarded Einstein an additional
degree. The other papers helped to develop modern physics and earned him the reputation
of an artist. Many scientists have said that Einstein's work contained an imaginative spirit that
was seen in most poetry. His work at this time dealt with molecules, and how their motion
affected temperature, but he is most well known for his Special Theory of Relativity which
tackled motion and the speed of light. Perhaps the most important part of his discoveries
was the equation: E= mc2.

After publishing these theories Einstein was promoted at his office. He remained at the
Patents Office for another two years, but his name was becoming too big among the
scientific community. In 1908, Einstein began teaching party time at the University of Berne,
and the following year, at the age of thirty, he became employed full time by Zurich
University. Einstein was now able to move to Prague with his wife and two sons, Hans
Albert and Eduard. Finally, after being promoted to a professor, Einstein and his family were
able to enjoy a good standard of living, but the job's main advantage was that it allowed
Einstein to access an enormous library. It was here that he extended his theory and
discussed it with the leading scientists of Europe. In 1912 he chose to accept a job placing
him in high authority at the Federal Institute of Technology, where he had originally studied.
It was not until 1914 that Einstein was tempted to return to Germany to become research
director of the Kaiser Wilhelm Institute for Physics.

World War I had a strong effect on Einstein. While the rest of Germany supported the army,
he felt the war was unnecessary, and disgusting. The new weapons of war which attempted
to mass slaughter people caused him to devote much of his life toward creating peace.
Toward the end of the war Einstein joined a political party that worked to end the war, and
return peace to Europe. In 1916 this party was outlawed by the government, and Einstein
was seen as a traitor.

In that same year, Einstein published his General Theory of relativity, This result of ten years
work revolutionized physics. It basically stated that the universe had to be thought of as
curved, and told how light was affected by this. The next year, Einstein published another
paper that added that the universe had no boundary, but actually twisted back on its self.

After the war, many aspects of Einstein's life changed. He divorced his wife, who had been
living in Zurich with the children throughout the war, and married his cousin Elsa Lowenthal.
This led to a renewed interest in his Jewish roots, and he became an active supporter of
Zionism. Since anti-Semitism was growing in Germany, he quickly became the target of
prejudice. There were many rumors about groups who were trying to kill Einstein, and he
began to travel extensively. The biggest change, though, was in 1919 when scientist who
studied an eclipse confirmed that his theories were correct.

In 1921, he traveled through Britain and the United States raising funds for Zionism and
lecturing about his theories. He also visited the battle sites of the war, and urged that Europe
renew scientific and cultural links. He promoted non-patriotic, non-competitive education,
believing that it would prevent war from happening in the future. He also believed that
socialism would help the world achieve peace.

Einstein received the Nobel Prize for Physics in 1922. He gave all the money to his ex-wife
and children to help with their lives and education. After another lecture tour, he visited
Palestine for the opening the Hebrew University in Jerusalem. He also talked about the
possibilities that Palestine held for the Jewish people. Upon his return he began to enjoy a
calmer life in which he returned to his original curiosity, religion.

While Einstein was visiting America in 1933 the Nazi party came to power in Germany.
Again he was subject to anti-Semitic attacks, but this time his house was broken into, and he
was publicly considered an enemy of the nation. It was obvious that he could not return to
Germany, and for the second time he renounced his German citizenship. During these early
years in America he did some research at Princeton, but did not accomplish much of

Albert Einstein

Inventor Project
April 1, 1996
Albert Einstein
My name is Albert Einstein. I was born on March 14, 1879 in Ulm,
Germany. I was not an inventor in the conventional sense. I was a physicist
and theorist. My inventions were not tangible things, but ideas I put on paper
and may later on have led to inventions. I was not a good student in school. I
did not pay attention to teachers because I found their lectures and teachings
boring. Often I would skip class to go study physics on my own. By the age
of twelve I had taught myself Euclidean Geometry, and slowly beginning to
develope my own theories in physics.
My first theoretical paper was on Brownian motion. The paper
discussed the significant predictions I made about particles that are randomly
distributed in a fluid. My next paper was on the photoelectric effect, which
contained a revolutionary hypothesis on the nature of light. I proposed that
under certain circumstances light can be considered as consisting of particles,
and I also hypothesized that energy carried by any light particle, called a
photon, is proportional to the frequency of the radiation. The formula for this
is E=hv, where E is the radiation, h is a universal constant known as Planck's
constant, and v is the frequency of the radiation. This proposal, that the
energy contained within a light beam is transferred by individual units, or
quanta, contradicted the hundred year old tradition of considering light as a
manifestation of continuous processes.
My third and most impotant paper, "On the Electrodynamics of
Moving Bodies", contained what has become known as the special theory of
relativity. Since the time of Sir Issac Newton, scientists had been trying to
understand the nature of matter and radiation, and how they interacted in
some unified world picture. The position that mechanical laws are
fundamental has become known as the mechanical world view, and the
position that electrical laws are fundamental has become known as the
electromagnetic world view. Neither approach, however, is capable of
providing a consistent explanation for the way radiation and matter interact
when viewed from different inertial frames of reference, that is, an interaction
viewed simultaneously by an observer at rest and an observer moving at
unifrom speed.
In the Spring of 1905 after considering these problems for ten years, I
realized that the crux of the problem lay not in a theory of matter but in a
theory of measuerment. At the heart of my special theory of relativity was the
realization thet all measurements of time and space depend on judgments as
to whether two distant events occur simultaneously. This led me to develope
a theory based on two postulates: the principle of relativity, that physical laws
are the same in all inertial reference systems, and the principal of the
invariance of the speed of light, that the speed of light in a vacuum is a
universal constant. I was thus able to provide a consistent and correct
description of physical events in different inertial frames of reference without
making special assumptions about the nature of matter or radiation, or how
they interact. This theory is best summed up in the equation E=mc2. Where
E is energy, m is mass, and c is the speed of light squared.
My final work was a failed attempt at trying to understand all physical
interactions, including electromagnetic interactions and weak and strong
inetractions. This has come to be known as the Unified Field Theory. Today
this theory has still not been proven by modern scientists.
Probably the most noticable invention to come from my work was born
from necessity. During World War II, it was believed here in the United
States that Nazi Germany was attempting to create an atomic bomb. As a
result of this believed, and startlingly real, threat the U.S. put forth a major
effort at construction of an atomic bomb. Even though I myself had no part in
the actual creation of the bomb, many of my theories where used.
This invention that came from my ideas does not help society in any
way, but it does hinder it considerably. Because of my invention we live in a
world that may cease to exist at the touch of a button by a power hungry
dictator. My invention is one of the most serious threats to existance of
mankind in today's world.
