Really really smart guy. Came up with the theory of relativity and the equation e = mc^2, which basically means that mass and energy are fundamentally related. Can also be used to describe someone who is really smart.
That guy got an A in Algorithms with prof. Brady! What an Einstein!

Albert Einstein, b. 1879, d. 1955.

Considered by many to be the greatest scientist of the 20th century, being named by Time magazine as "Man of the Century".

A physicist, he won a Nobel Prize for his discovery of the photoelectric effect (1905), which explained how a photon causes an electron to be emitted from a metallic surface when illuminated by light, by postulating that photons are discrete "quanta" of energy.

He also devised the Theory of Special Relativity (1905), which deals with the perception of time and distance between observers in different frames of reference that are moving relative to each other, and postulated that the speed of light is the same in all frames of reference.

Later he expanded this into the Theory of General Relativity (1907), which explains the force of gravity as a geometric warping of space-time and treats acceleration and gravity as equivalent forces acting on matter.

Born a Jew in Germany, he came to America just prior to the Nazi's rise to power (1932), and never returned to his homeland.

He spent the last years of his life attempting to combine the fundamental forces into a single unified field theory, but without success.

Ironically, his name is used as a derogatory term for persons who proclaim something obvious or who do something especially stupid.
Well he's bright, but he's no Einstein.

That was a really smart move, Einstein!

You can't tie your shoelaces and chew gum at the same time, can you, Einstein?

*Full Name : Albert Einstein. Albert Einstein was an intelligent man who theorized many scientific fields that we, to this day, are continuing to research. He is generally credited for developing the theory of relativity, and is perhaps the father of the nuclear age.

*A name used to relay something obvious toward one who seems to not have the common knowledge.

"Hey Einstein that was a civilian! *slaps him upside the back of the head*"
-a soldier

A female that's very good with her head. Not necessarily talking about intelligence but giving great oral sex.

1. German for "One Stone".

2. The last name of the most brilliant man of the 20th century.
1. Ich habe eine Stein. (What I wanted to say was 'Ich habe ein Stein' but German grammar says that 'Stein' is feminine.)

2. Hey Bill, you ever heard of THE MAN called on the streets as Einstein, yo?
