The relativity principle in connection with the basic Maxwellian equations demands that the mass should be a direct measure of the energy contained in a body; light transfers mass. With radium there should be a noticeable diminution of mass. The idea is amusing and enticing; but whether the Almighty is laughing at it and is leading me up the garden path -- that I cannot know.
I remember I went to an exhibition somewhere and one of the artists, an Iranian lady, said, "I wish we had somewhere that our paintings would stay forever. " So this idea came to me. I said, "She's right, we should have a place to keep them, and not only Iranian art works, but also of foreign artists. "
