My favourite quotes from great scientists that could inspire graduate students
“as far as I know, no one undertook to repeat the experiments” – Father Gregor Mendel writing on his biggest frustration after publishing his theories of inheritance. Mendel’s work was eventually recognized 14 years after his death.
“Anyone who has truly experienced how knowledge is accomplished would recognise the infinity of other truths of which he understands nothing” – Galileo Galilei writing in his Dialogue concerning Two World Systems. This is the famous book had led him to the Inquisition.
“This is beginning to bore me.” – Albert Einstein on learning that he flunked his PhD exams twice. Einstein eventually got his PhD with an elegant thesis on Brownian Motion.
