Everything must be made as simple as possible. But not simpl... - Albert Einstein

"Strange is our situation here on Earth. Each of us comes for a short visit, not knowing why, yet sometimes seeming to divine a purpose. From the standpoint of daily life, however, there is one thing we do know: that man is here for the sake of other men - above all for those upon whose smiles and well-being our own happiness depends."

"Never memorize something that you can look up."

"The most incomprehensible thing about the world is that it is at all comprehensible."

"Logic will get you from A to Z; imagination will get you everywhere."

"One thing I have learned in a long life: that all our science, measured against reality, is primitive and childlike -- and yet it is the most precious thing we have."
