Einstein's first letter to Roosevelt Notes: The letter that launched the arms race.
Thursday, December 10, Early life and education Einstein at the age of 4. Inthe family moved to Munich, where his father and his uncle founded Elektrotechnische Fabrik J.
From Euclid, Einstein began to understand deductive reasoning, and by the age of twelve, he had learned Euclidean geometry.
Soon after he began to investigate infinitesimal calculus. At age 16, he performed the first of his famous thought experiments in which he visualized traveling alongside a beam of light.
Their son attended a Catholic elementary school from the age of five until ten. The Jewish community arranged for Talmud to take meals with the Einsteins each week on Thursdays for six years. During this time Talmud wholeheartedly guided Einstein through many secular educational interests.
In search of business, the Einstein family moved to Italy, first to Milan and then, a few months later, to Pavia. When the family moved to Pavia, Einstein stayed in Munich to finish his studies at the Luitpold Gymnasium.
He later wrote that the spirit of learning and creative thought were lost in strict rote learning. Lacking the requisite Matura certificate, he took an entrance examination, which he failed, although he got exceptional marks in mathematics and physics. His sister Maja later married the Winteler son, Paul.
Marie Winteler moved to Olsberg, Switzerland for a teaching post. Their second son, Eduard, was born in Zurich in July InEinstein moved to Berlin, while his wife remained in Zurich with their sons. She was his first cousin maternally and his second cousin paternally.
Inthey emigrated permanently to the United States. InElsa Einstein was diagnosed with heart and kidney problems and died in December, The next year, Einstein published a paper in the prestigious Annalen der Physik on the capillary forces of a straw. Most were about physics, but a few expressed leftist political opinions about pacifism, socialism, and zionism.
The reason physicists were skeptical was because no 19th century theory could fully explain the properties of matter from the properties of atoms. Ludwig Boltzmann was a leading 19th century atomist physicist, who had struggled for years to gain acceptance for atoms.
Boltzmann had given an interpretation of the laws of thermodynamics, suggesting that the law of entropy increase is statistical. The reason the entropy goes up is only because it is more likely for a system to go from a special state with only a few possible internal configurations to a more generic state with many.
The statistical idea was most successful in explaining the properties of gases. James Clerk Maxwell, another leading atomist, had found the distribution of velocities of atoms in a gas, and derived the surprising result that the viscosity of a gas should be independent of density.
Intuitively, the friction in a gas would seem to go to zero as the density goes to zero, but this is not so, because the mean free path of atoms becomes large at low densities. A subsequent experiment by Maxwell and his wife confirmed this surprising prediction.
In addition to these successes, there were also inconsistencies. Maxwell noted that at cold temperatures, atomic theory predicted specific heats that are too large. A monatomic solid with N atoms can be thought of as N little balls representing N atoms attached to each other in a box grid with 3N springs, so the specific heat of every solid is 3NkB, a result which became known as the Dulong-Petit law.
This law is true at room temperature, but not for colder temperatures. At temperatures near zero, the specific heat goes to zero. Similarly, a gas made up of a molecule with two atoms can be thought of as two balls on a spring. This spring has energy kBT at high temperatures, and should contribute an extra kB to the specific heat.
It does at temperatures of about degrees, but at lower temperature, this contribution disappears.Albert Einstein was widely known during his lifetime for his work with the theory of relativity and physics in general.
He was also an important peace activist, a world federalist and a timberdesignmag.com political opinions were of public interest through the middle of the 20th century due to his fame and involvement in political, humanitarian and academic projects around the world.
Einstein's exact religious thought is a cause of controversy for many. He is often quote mined by Preachers, about him stating that the universe is to complex not to be created by a god. It is noted that Einstein was disdainful of organized religion.

Sir: Some recent work by timberdesignmag.com and L. Szilard, which has been com- municated to me in manuscript, leads me to expect that the element uran- ium may be turned into a new and important source of energy in the im- mediate future.
Albert Einstein was one of the twentieth centuries most influential people, both as a scientist and a public figure. Although Einstein was a mathematician he is better known for his work in the field of theoretical physics, and through his work he helped change the realm of physics for years to come.
Einstein’s views on socialism. In , Einstein wrote an article for the magazine Monthly Review explaining his thoughts on socialism. In it, he explains his political positions and why he feels the need to weigh in on a subject that is outside his area of expertise. Albert Einstein was a complicated human being, with a wide range of interests.
His personality seemed balanced between a certain chilliness when it came to personal matters, and a great deal of warmth and compassion when it came to the wider human family.
