Who was Albert Einstein and what did he contribute to electricity?
Albert Einstein (1879-1955). Einstein's formula proved that one gram of mass can be converted into a torrential amount of energy. To do this, the activity of the atoms has to occur in the nucleus. E = energy, M = mass, and C = the speed of light which is 186,000 miles per second. When you square 186,000 you can see it would only take a small amount of mass to produce a huge amount of energy.
In one of the papers, Einstein suggested that light could be thought of as a stream of tiny particles. This idea forms an important part of the quantum theory. In 1900, the German physicist Max K. E. L. Planck had proposed that the radiation of light occurred in packets of energy, called quanta. Einstein extended this idea by arguing that light itself consisted of quanta, which were later called photons. Scientists before Einstein had discovered that a bright beam of light striking a metal caused the metal to release electrons, which could form an electric current. They called this phenomenon the photoelectric effect. But scientists could not explain the phenomenon as long as they assumed that light traveled only in waves. Using his theory of quanta, Einstein explained the photoelectric effect. He showed that when quanta of light energy strike atoms in a metal, the quanta force the atoms to release electrons. Einstein's paper established the theoretical basis for the photoelectric cell, or "electric eye." This device made possible sound motion pictures, television, and many other inventions. Einstein received the 1921 Nobel Prize in physics for this paper on quanta.
In a second paper, titled "The Electrodynamics of Moving Bodies," Einstein presented the special theory of relativity. In this paper, he showed how the theory demonstrated the relativity of time, a previously unimaginable idea. Einstein's name is most widely known for this theory. In a study published in 1905, Einstein showed the equivalence of mass and energy, expressed in the famous equation E=mc2.
Albert's father worked at an electric shop, which made batteries. This is how Albert became curious about electricity and science. In school, Albert Einstein did poorly in school, except for mathematics, where he excelled. While in school, Albert was puzzled about electricity and algebra. Albert went to work with his dad after school in the afternoons. One day when Albert was ten and a half, he met a student named Max while he was trying to save a stork from a freezing lake. Max was a student who brought Albert home to dinner. He taught Albert about math and other things.
Albert Einstein was much respected for his kind and friendly demeanor rooted in his pacifism. He was modest about his abilities, and had distinctive attitudes and fashions—for example, he minimized his wardrobe so that he would not need to waste time in deciding on what to wear. He occasionally had a playful sense of humor, and enjoyed sailing and playing the violin. He was also the stereotypical "absent-minded professor"; he was often forgetful of everyday items, such as keys, and would focus so intently on solving physics problems that he would often become oblivious to his surroundings.
