Albert Einstein and his Invention Prakash Rawal   © Copyright 2021 by Prakash Rawal

Albert Einstein was born on March 14 , 1879 in UIM,  Germany.  He was not talkative in his childhood,  and until the three , he didn't talk much . He spent his teenage years in Munich, where his family had an electric equipme business. As a teenager,  he was interested in nature and showed a high level of ability in mathematics and physics. Einstein loved to Tobermory creative and innovative. He loathed the uncreative spirit in his school at Munich. His family business failed when he was aged 15, and they moved to Milan ,Italy. Aged 16, he moved to Switzerland,  where I finished high school. In 1896, he  began to study for a degree at the Swiss Federal Institute of Technology in Zurich. He didn't like the teaching methods there , so he bunked classes to carry out experiment in the physics laboratory or play his violin. With the help of his classmate notes, he passed his exams ; he graduated in 1900. Einstein was not considered a good student by his teachers, and they refused to recommend him for further employment.  Einstein 1903. While studying at the polytechnic,  Einstein had learned about one of the biggest problems then baffling physicists.This was how to marry together Isaac Newton's  laws of motion with James Clerk Maxwell's equation of electromagnetism In 1902, he obtained the post of an examiner in the Swiss Federal patent office , and , in 1903 , he wedded his classma Mileva Maric.  He had two sons with her but they later divorced. After some years Einstein married Elsa Loewenthal. Einstein continued to work in the patent office , during which time he made most of his greatest scientist breakthroughs.  The University of Zurich awarded him a Ph.D. in 1905 for his thesis "A New Determination Molecular Dimensions".In 1905 , the same year as he submitted his doctoral thesis , Albert Einstein published four immensely important scientist papers dealing with his analysis of : Brownian Motion; the equivalence of mass and energy ; the photoelectric effect ; and special relativity . Each of these papers on their own was a huge contribution to science . To publish of such papers of one year was considered to be almost miraculous.  Einstein was just 26 years old. Einstein gave birth in 1905 to what has become the world's most famous equation. The equation says that mass (m) can be converted to energy (E) A little mass can make a lot of energy,  because mass multiplied by c2 where can is the speed of light , a very large number. A small amount of mass can make a large amount of energy. Conversion of mass in atomic nuclei to energy is till principal behind nuclear weapons, and explains the sun's source of energy. If you shine light on metal , the metal may release some of its electrons. Einstein said that light is made up of individual ' particle' of energy , which he called quanta. When these quanta hit the metal , they give their energy to elector giving the electrons enough to escape from the metal . Einstein showed that light can behave as a particle as well as a wave. The energy each 'particle' of light carries proportional  to the frequency of the light waves. In Einstein 's third paper of 1905 , he returned to the big problem he had heard about at university -how to resolve Newton's laws of motion with Maxwell's  equation of light . His approach was the ' thought experiment ' . He imagine how the world would look if he could travel at the speed of light . He realized that the laws of physics are the same everywhere and that , regardless of what you did - whether you move quickly towards a ray of lights as it approached you , or quickly away from the ray of light - you would always see the light ray to be moving at the same speed - the speed of light! This is not obvious , because it's not how things work in everyday life , where , for example,  if you move towards a approaching you on a bike he will reach you sooner than if you move away from him.With light , it doesn't matter whether you move towards or away from the light , it will take the same amount of time to reach you . This isn't an easy thing to understand,  so don't worry about it if you don't. Eve experiment ever done to test special relativity has confirmed what Einstein said. If the speed of light is the same for all observes , regardless of their speed , then it follows that some other strange things must be true . In fact , it turns out that time , length and mass actually depend on the speed we are moving at . The nearer the speed of light we are moving at , the bigger differences we seen in these quantities compared with someone moving more slowly . For example,  time passes more and more slowly as we move faster and faster. As people read Einstein's papers and argued about their significance , his work gradually gained acceptance , and his reputation as a powerful new intellect in the world of physics grew.In 1908 he began lecturing at the University Bern, and the following year resigned from the patent Office. In 1911 he became a professor of physics at the Ferdinand University in Prague, before returning to Zurich in 1912 to a professorship there. Woking on the general theory of relatively, In 1911 he made his first predictions of how our Sun's powerful gravity would bend the path of light coming from other stars as it traveled past the Sun. A very rough approximation :the earth 's mass curves space. The moon 's space keeps it rolling around the corner rath than falling to Earth. If  you are on Earth and wish to leave , you need to climb out of the gravity well Einstein published his general theory of relativity paper 1915 , showing , for example,  how gravity distorts space and time . Light is deflected by powerful gravity,  not because of its mass but because gravity has curve the space that the light travel through . In 1919 , a British expedition set out to the west African island of principles to observe the sun. Einstein had been born German and a jew.He died an American  citizen in 1955.
