"Imagination is more important than knowledge."
                            -Albert Einstein

"Common sense is the collection of prejudices acquired by age eighteen." 
                            -Albert Einstein

"All means prove but a blunt instrument, if they have not behind
 them a living spirit. But if the longing for the achievement of
 the goal is powerfully alive within us, then we shall not lack
 the strength to find the means for reaching the goal and for
 translating it into deeds."
                            -Albert Einstein

"Physical concepts are free creations of the human mind, and
 are not, however it may seem, uniquely determined by the
 external world.

 In our endeavor to understand reality we are somewhat like
 a man trying to understand the mechanism of a closed
 watch. He sees the face and the moving hands, even hears
 its ticking, but has no way of opening the case.

 If he is ingenious he may form some picture of a
 mechanism which could be responsible for all things he
 observes, but he may never be quite sure his picture is the
 only one which could explain his observation. He will never
 be able to compare his picture with the real mechanism and
 he can not imagine the possibility or the meaning of
 such a comparison."
                            -Albert Einstein
                             THE EVOLUTION OF PHYSICS
                             1938

"Books on physics are full of complicated mathematical formulae. But thought
 and ideas, not formula, are the beginning of every physical theory."
                            -Albert Einstein

"Through the release of atomic energy, our generation has brought into the
 world the most revolutionary force since prehistoric man's discovery of fire.
 This basic force of the universe cannot be fitted into the outmoded concept of
 narrow nationalisms.  For there is no secret and there is no defense; there is
 no possibility of control except through the aroused understanding and
 insistence of the peoples of the world. We scientists recognise our
 inescapable responsibility to carry to our fellow citizens an understanding
 of atomic energy and its implication for society.  In this lies our only
 security and our only hope - we believe that an informed citizenry will act
 for life and not for death."

                            -Albert Einstein
                             22 January 1947


Concern for man himself and his fate
must always form the chief interest of
all technical endeavors ... in order that
the creations of our mind shall be a
blessing and not a curse to mankind. Never
forget this in the midst of your diagrams
and equations.
                           -Albert Einstein, 1931
