Explanation:
In 1905
Albert
Einstein had a miraculous
year.
One hundred
years ago, he wrote four papers which
revolutionized our understanding of the Universe.
The papers outlined;
the idea that
light could behave as a
quantized particle (a photon),
an explanation of the
thermal
motion of atoms and molecules
(at a time when atoms themselves were just theories),
a theory reconciling motion
and the constant speed of light
(Special
Relativity), and
the idea of
mass-energy
equivalence
(E=mc²).
Virtually every facet of our modern exploration of the Universe
is touched by his now century old insights, along with his later
theory of
gravity
and space-time - General Relativity.
In centennial celebration, consider this thoughtful view of
a small telescope beside the
Einstein
Memorial on the grounds of the
National Academy of Sciences in Washington DC, USA.
The marble platform at the bronze statue's feet is embedded with a
map showing the positions of the planets, sun, moon and stars
on the memorial's dedication date, 100 years after Einstein's birth
in 1879.
Albert
Einstein died 50 years ago, on April 18, 1955.
