Linus Pauling — "The pursuit of knowledge is an endless journey."

"I confess that I had harbored the feeling that sooner or later I would be the one to get the DNA structure; and although I was pleased with the double-helix, I 'rather wished the idea had been his'."

"I have always been a curious person, and I believe that curiosity is the key to discovery."

"I believe that science and ethics are inextricably linked, and that we have a responsibility to use our knowledge wisely."

"The only way to cope with a problem is to go right at it, and the only way to solve a problem is to keep on working at it until you've solved it."

"The greatest discoveries of science have always been made by those who were not afraid to challenge the existing paradigms."
