"In theory, practice should work like theory...." - Quote by Yogi Berra

“Everything should be built top-down, except the first time.”

“I can't concentrate when I'm thinking.”

“Referring to the bad sun conditions in left field at the stadium: It gets late out there early.”

“Ours has not been unadulterated nonviolence in thought, word and deed.”

“The astonishment of life is the absence of any appearances of reconciliation between the theory and the practice of life.”

“Those who fall in love with practice without science are like a sailor who enters a ship without a helm or a compass, and who never can be certain whither he is going.”

“Well, it may be all right in practice, but it will never work in theory”

“If the facts don't fit the theory, change the facts.”

“The theory must not contradict empirical facts.”
