This is Steve Ember. Today we tell about a scientist who changed the way we understand the universe, Albert Einstein. In the yearAlbert Einstein published some important papers in a German scientific magazine. They included one of the most important scientific documents in history.
Upon graduation, Einstein could not find a higher education teaching post. The father of a classmate helped him obtain a job as a technical assistant examiner at the Swiss Patent Office in He obtained his doctorate after submitting his thesis "A new determination of molecular dimensions" in The science career of Albert Einstein really took off in that year, He wrote four articles that provided the foundation of modern physics.
The papers were on Brownian motion, the photoelectric effect and special relativity. He won the Nobel Prize for physics in with the paper on the photoelectric effect. Einstein's third paper that year, "On the Electrodynamics of Moving Bodies" introduced the special theory of relativity.
This was the turning point in the career of Albert Einstein. Albert Einstein From toEinstein moved considerably between academic institutions in Europe until he became full professor at the ETH Zurich in It was during this period that he published a paper on why the daytime sky is blue.
General Relativity In NovemberEinstein presented a series of lectures before the Prussian Academy of Sciences in which he described his theory of gravity, known as general relativity. The final lecture climaxed with his introduction of an equation that replaced Newton's law of gravity, Einstein's Field Equations.
This was really the defining moment in the career of Albert Einstein. Initially, scientists were skeptical because the general theory of relativity was not derived by experiment or observation, but by pure mathematical reasoning and rational analysis.
After the confirmation of the prediction of how much the light from a star will be bent by the Sun's gravity when it passed close to the Sun, acceptance increased dramatically.
On November 7, The Times reported the confirmation, cementing Einstein's fame forever. In the early s Einstein was the lead figure in a famous weekly physics colloquium at the University of Berlin.
Though he is now most famous for his work on relativity, at that time his work on general relativity was still disputed, so it was for his earlier work on the photoelectric effect that he was given the Prize. The Nobel committee decided that citing his less-contested theory in the Prize would gain better acceptance from the scientific community.
This article introduced the concept of stimulated emission, the physical principle that allows light amplification in the laser.
He also published a paper that year that used the general theory of relativity to model the behavior of the entire universe, setting the stage for modern cosmology.
In this work he created his self-described "worst blunder", the cosmological constant. In the mids the original quantum theory was replaced with a new theory of quantum mechanics.
Einstein balked at the Copenhagen interpretation of the new equations, either because it settled for a probabilistic, non-visualizable account of physical behavior, or because it described matter as being in necessarily contradictory states.
Einstein agreed that the theory was the best available, but he looked for a more "complete" explanation, i. He could not abandon the belief that physics described the laws that govern "real things", the belief which had led to his successes with atoms, photons, and gravity.
In a letter to Max Born, Einstein made a remark that is now famous: But an inner voice tells me it is not yet the real thing. The theory says a lot, but does not really bring us any closer to the secret of the Old One. I, at any rate, am convinced that He does not throw dice.
Einstein was not rejecting probabilistic theories per se. Einstein himself was a great statistician, using statistical analysis in his works on Brownian motion and photo-electricity and in papers published before the miraculous year ; Einstein had even discovered Gibbs ensembles.
He believed, however, that at the core reality behaved deterministically. Many physicists argue that experimental evidence contradicting this belief was found much later with the discovery of Bell's Theorem and the so-called 'Bell's Inequality'.
Nonetheless, there is still space for lively discussions about the interpretation of quantum mechanics. Bose-Einstein Statistics InEinstein received a short paper from a young Indian physicist named Satyendra Nath Bose describing light as a gas of photons and asking for Einstein's assistance in publication.
Einstein realized that the same statistics could be applied to atoms, and published an article in German then the lingua franca of physicswhich described Bose's model and explained its implications.Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire, on 14 March His parents were Hermann Einstein, a salesman and engineer, and Pauline rutadeltambor.com , the family moved to Munich, where Einstein's father and his uncle Jakob founded Elektrotechnische Fabrik J.
Einstein & Cie, a company that manufactured electrical equipment based on direct current. Albert Einstein was a famous physicist. His research spanned from quantum mechanics to theories about gravity and motion. After publishing some groundbreaking papers, Einstein toured the world and gave speeches about his discoveries.

Today we tell about a scientist who changed the way we understand the universe, Albert Einstein. Who would have thought that one of history’s most renowned geniuses and a slapstick silent movie star would hit it off? And yet they did. Charlie Chaplin first met Albert Einstein on the famed. Early life and education.
Einstein was born on March 14, , to a Jewish family, in Ulm, Wurttemberg, Germany. His father was Hermann Einstein, a salesman who later ran an electrochemical works, and his mother was Pauline nŽe Koch.
Albert Einstein and Religion (The following quotes are taken from The Quotable Einstein, Princeton University Press unless otherwise rutadeltambor.com all reinforce Walter Isaacson who wrote on page in his landmark book on Einstein, Einstein: His Life and Universe, that Einstein “held a deistic concept of God.”) " My religion consists of a humble admiration of the illimitable superior spirit.
