Happy Birthday Albert Einstein! How much do you really know about this great scientist? ⬇️
Albert Einstein was a German-American physicist and probably the most well-known scientist of the 20th century. He is famous for his theory of relativity , a pillar of modern physics that describes the dynamics of light and extremely massive entities, as well as his work in quantum mechanics , which focuses on the subatomic realm.
In 1896, at age 17, Einstein entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. A few years later, he gained his diploma and acquired Swiss citizenship but was unable to find a teaching post. So he accepted a position as a technical assistant in the Swiss patent office.
How Einstein changed physicsEinstein obtained his doctorate in physics in 1905 — a year that's often known as his annus mirabilis , according to the Library of Congress . That year, he published four groundbreaking papers of significant importance in physics. In 1915, Einstein published four papers outlining his theory of general relativity, which updated Isaac Newton's laws of gravity by explaining that the force of gravity arose because massive objects warp the fabric of space-time. The theory was validated in 1919, when British astronomer Arthur Eddington observed stars at the edge of the sun during a solar eclipse and was able to show that their light was bent by the sun's gravitational well, causing shifts in their perceived positions.
Bohr and Einstein famously clashed over quantum mechanics. Bohr and his cohorts proposed that quantum particles behaved according to probabilistic laws, which Einstein found unacceptable, quipping that"God does not play dice with the universe ." Bohr's views eventually came to dominate much of contemporary thinking about quantum mechanics.
