Albert Einstein (1879-1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is known for its influence on the philosophy of science. Here are some key points about Einstein:
Special and General Relativity:
Special Relativity (1905): Introduced the concept that the laws of physics are the same for all non-accelerating observers and showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels. This led to the famous equation
𝐸
=
𝑚
𝑐
2
General Relativity (1915): Expanded the theory of special relativity to include gravity, proposing that massive objects cause a distortion in space-time, which is felt as gravity.
Nobel Prize in Physics: In 1921, Einstein was awarded the Nobel Prize in Physics for his explanation of the photoelectric effect, which was pivotal in establishing quantum theory.
Major Works and Contributions:
Photoelectric Effect: Demonstrated that light could be understood as quanta of energy (photons), helping to establish quantum theory.
Brownian Motion: Provided empirical evidence for the existence of atoms.
Quantum Mechanics: Though initially skeptical, Einstein made significant contributions to the development of quantum mechanics, though he later famously disagreed with its probabilistic nature, encapsulated in his quote, "God does not play dice with the universe."
Later Years and Legacy:
Einstein emigrated to the United States in 1933 after the rise of the Nazi regime, taking a position at the Institute for Advanced Study in Princeton, New Jersey.
He was an advocate for civil rights and was offered the presidency of Israel, which he declined.
Einstein spent his later years working on a unified field theory, attempting to reconcile general relativity and quantum mechanics, though this work remained unfinished.
Einstein's intellectual achievements and originality have made the name "Einstein" synonymous with "genius."
