Someone told me that each equation I included in the book would halve the sales. - Stephen Hawking

In Einstein's equation, time is a river. It speeds up, meanders, and slows down. The new wrinkle is that it can have whirlpools and fork into two rivers. So, if the river of time can be bent into a pretzel, create whirlpools and fork into two rivers, then time travel cannot be ruled out. - Michio Kaku

I am a great fan of science, but I cannot do a quadratic equation. - Terry Pratchett

Physics is nothing but the ABC's. Nature is an equation with an unknown, a Hebrew word which is written only with consonants to which reason has to add the dots. - Johann G. Hamann

Politics is for the present, but an equation is for eternity. - Albert Einstein

Science is global. Einstein's equation, E=mc2, has to reach everywhere. Science is a beautiful gift to humanity, we should not distort it. Science does not differentiate between multiple races. - A.P.J. Abdul Kalam

I'm a student of patterns. At heart, I'm a physicist. I look at everything in my life as trying to find the single equation, the theory of everything. - Will Smith

Nothing changes the gender equation more significantly than women's economic freedom. - Gloria Steinem

Science is a differential equation. Religion is a boundary condition. - Alan Turing

String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation. - Brian Greene

When I get bored, or get stuck on an equation, I like to go ice skating, but it makes you forget your problem. Then you can tackle the problem with a fresh new insight. Einstein liked to play the violin to relax. Every physicist likes to have a past time. Mine is ice skating. - Michio Kaku

You can't be afraid of getting old. Old is good, if you're gathering in life. Our band is good at understanding that equation. - Bruce Springsteen

Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality. - Nikola Tesla

Adam and Eve are like imaginary numbers, like the square root of minus one... If you include it in your equation, you can calculate all manners of things, which cannot be imagined without it. - Philip Pullman

It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent. - Richard P. Feynman

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation. - David Gross
