Albert Einstein: 1879 - 1955
Einstein is considered by many the greatest astrophysicist. He is
pictured here in the Swiss Patent Office where he did much of his great work.
Einstein's many visionary scientific contributions include the
equivalence of mass and energy (E=mc^2), how the maximum speed limit of light
affects measurements of time and space
(special relativity), and a more accurate theory of gravity based on
simple geometric concepts
(general relativity). One reason
was awarded the 1921
Nobel Prize in Physics was to make the prize more prestigious.
