Quote by Lakatos, Imre

"Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true."

"Science grows by the process of rational criticism and the elimination of error."

"The history of science is a history of competing research programmes."

"Criticism is the lifeblood of science."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
