Albert Einstein

Albert Einstein was a German-born theoretical physicist best known for developing the special and general theories of relativity.

Updated August 1, 20261 min readCited sources

Albert Einstein was a German-born theoretical physicist who reshaped modern physics with his theories of relativity and the photoelectric effect.

What it is

Einstein developed the special theory of relativity in 1905 and the general theory of relativity in 1915. His mass–energy equivalence formula, E=mc², is among the most recognized equations in physics. He also explained the photoelectric effect, for which he won the 1921 Nobel Prize in Physics.

Why it matters

Einstein's work transformed the understanding of space, time, gravity, and light. It remains foundational to physics education, research, and technology in Canada, including university teaching and scientific work in relativity and quantum physics.

Key details

Born in Ulm, Germany, in 1879, Einstein later became a Swiss and U.S. resident. He died in Princeton, New Jersey, in 1955. His Nobel Prize was awarded for the photoelectric effect, not relativity, though both contributions are central to his legacy.

In short

  • Developed special and general relativity
  • Won 1921 Nobel Prize for photoelectric effect
  • Famous for E=mc² equation
  • Born 1879 in Germany, died 1955 in US
Canadian angle

Einstein has no direct Canadian identity, but his theories are foundational to physics education, research, and technology in Canada, including university teaching and scientific work in relativity and quantum physics.
