Richard Feynman on String Theory: 'I have noticed when I was younger that a lot of old men in the field couldn’t understand new ideas very well... I’m an old man now, and these are new ideas, and they look crazy to me, and they look like they’re on the wrong track.'

'We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems... Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.' -Richard Feynman, "The Value of Science" (1955)

Tributes at Bryn Mawr College to the brilliant mathematician Emmy Noether, who spent her final years there. Noether revolutionized the methods of modern physics by identifying continuous symmetry groups with conservation laws. The third image is her grave marker. #Mathematics

Marvellous portrait of physicist Richard Feynman dressed as a Ladakhi monk for a costume party, painted by Pasadena artist Sylvia Posner. The 'lightning bolt' he is clutching in his right hand resembles one of his scientific diagrams.
