Quote by Sheldon Glashow
"A theory that cannot be tested is merely philosophy dressed in scientific clothing."
More from Sheldon Glashow
"The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy."
"In physics, you don't have to go around making trouble for yourself—nature does it for you."
"A theory is something nobody believes, except the person who made it. An experiment is something everybody believes, except the person who made it."
"I believe that today's scientists have a responsibility to think carefully about the implications of their work."
