Einstein determined that motion through space can also be thought of as motion through time. In essence, space and time affect each other, both being relative concepts in relation to the speed of light. For anyone that has made it through a high school chemistry class, Avogadro's number might ring a bell.
While Einstein was working to develop his mathematical model for explaining Brownian motion, the erratic movement of particles in a fluid, he also proved the existence of atoms, and laid the foundation for calculating Avogadro's number, the number of atoms in one mole of molecule or an element.
Einstein's work on Brownian motion suggested the existence of tiny indistinguishable particles. This theory was later proven by Jean Perrin, who carried out experiments using a high precision microscope to verify Einstein's mathematical work. This allowed Perrin to calculate Avogadro's number and prove the existence of atoms — for which he received the Nobel Prize in In , Einstein was sent a paper from physicist Satyendra Nath Bose.
This paper discussed a detailed way to think of photons of light as a gas. Einstein worked with Bose to extend this idea to atoms , which led to a prediction for a new state of matter: the Bose-Einstein Condensate.
The first example of this state was produced in He also predicted that at sufficiently low temperatures, the particles would become locked together in the lowest quantum state of the system.
This phenomenon is called Bose-Einstein condensation. A Bose-Einstein condensate is essentially a group of atoms that are cooled very close to absolute zero. When they reach that temperature, they hardly move in relation to one another.
They begin to clump together and enter into exactly the same energy states. This means that, from a physical point of view, the group of atoms behaves as if they were a single atom. In , Einstein published his G eneral Theory of Relativity. In an entry for November , Einstein refers to residents of Hong Kong as "industrious, filthy, lethargic people Even the children are spiritless and look lethargic.
It would be a pity if these Chinese supplant all other races. At the time the Nazis, led by Adolf Hitler , were gaining prominence with violent propaganda and vitriol in an impoverished post- World War I Germany. The Nazi Party influenced other scientists to label Einstein's work "Jewish physics. Meanwhile, other European scientists also left regions threatened by Germany and immigrated to the U.
After moving, Einstein never went back to his native land. It was at Princeton that Einstein would spend the rest of his life working on a unified field theory—an all-embracing paradigm meant to unify the varied laws of physics. Not long after he began his career at Princeton, Einstein expressed an appreciation for American "meritocracy" and the opportunities people had for free thought, a stark contrast to his own experiences coming of age.
In , Einstein was granted permanent residency in his adopted country and became an American citizen five years later. During World War II , he worked on Navy-based weapons systems and made big monetary donations to the military by auctioning off manuscripts worth millions. Roosevelt to alert him of the possibility of a Nazi bomb and to galvanize the United States to create its own nuclear weapons. The U. Einstein was also the recipient of much scrutiny and major distrust from FBI director J. Edgar Hoover.
After learning of the bombing of Hiroshima , Japan, Einstein became a major player in efforts to curtail usage of the a-bomb. The following year he and Szilard founded the Emergency Committee of Atomic Scientists, and in , via an essay for The Atlantic Monthly , Einstein espoused working with the United Nations to maintain nuclear weapons as a deterrent to conflict.
Du Bois as well as performing artist Paul Robeson and campaigned for civil rights, calling racism a "disease" in a Lincoln University speech. After World War II, Einstein continued to work on his unified field theory and key aspects of his general theory of relativity, including time travel, wormholes, black holes, and the origins of the universe. However, he felt isolated in his endeavors since the majority of his colleagues had begun focusing their attention on quantum theory. In the last decade of his life, Einstein, who had always seen himself as a loner, withdrew even further from any sort of spotlight, preferring to stay close to Princeton and immerse himself in processing ideas with colleagues.
The previous day, while working on a speech to honor Israel's seventh anniversary, Einstein suffered an abdominal aortic aneurysm. He was taken to the hospital for treatment but refused surgery, believing that he had lived his life and was content to accept his fate. I have done my share, it is time to go.

A young Albert Einstein sits at his desk. Einstein wasn't an inventor but his work led to many important advances. Brownian movement , or the zigzag motion of microscopic particles in suspension. Einstein's findings helped to prove the existence of atoms and molecules. The quantum theory of light. Einstein proposed that light is composed of separate packets of energy, called -- quanta or photons -- that have some properties of particles and some properties of waves.
He also explained the photoelectric effect , which is the emission of electrons from some solids when they're struck by light. Television is a practical application of Einstein's theory of light.
Since Einstein gave his lectures, what impact have his discoveries had on our everyday lives in the century? It's hard to get lost these days because of GPS - it's what allows our satnavs satellite navigation systems and smartphone map apps to tell us the quickest route to the restaurant or the beach.
But if it weren't for Einstein's general theory of relativity, we wouldn't know to take relativity's effects into account when synchronizing the network of Global Positioning System GPS satellites orbiting the Earth. And with each GPS satellite containing several atomic clocks, the clocks on your computer and mobile phone are ultra-accurate. Einstein's discovery of the physical principle was responsible for the light amplification by stimulated emission of radiation the long-winded way of saying laser that made these devices possible.
These are just three examples - there's virtually no corner of science and technology that hasn't experienced the Einstein effect, from supercomputers and supernovas to nuclear weapons and the Big Bang.
