  Einstein in 1905, his year of miracles, wrote five papers which mark a
watershed between classical physics and modern physics. They dealt with problem
of reality of atoms, theory of special relativity which overthrew Newtonian
conceptions of space and time, and his revolutionary light quantum hypothesis
which together with Planck's work on black body radiation started the quantum
revolution. We put these discoveries in the context of that period and also
indicate their later influence.
