Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy via a series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes the last one upward. The device is also known as Newton's balls or "Executive Ball Clicker".

“I frame no hypotheses; for whatever is not deduced from the phenomena is to be called a hypothesis; and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy.”
—Isaac Newton (1642–1727)
“The ancients adorned their sarcophagi with the emblems of life and procreation, and even with obscene symbols; in the religions of antiquity the sacred and the obscene often lay very close together. These men knew how to pay homage to death. For death is worthy of homage as the cradle of life, as the womb of palingenesis.”
—Thomas Mann (1875–1955)
