Energy is neither created nor destroyed; the illusion of Grief.

Richard Feynman, a physicist, was one of the most intriguing people of the 20th century. He helped construct the atom bomb, won the Nobel Prize, wrote numerous books, sought every fundamental force, was a loved teacher, pseudoscience myth buster, and a well-respected public intellectual.

When Richard lost his wife, he started writing letters and storing them away in 1946, a year and four months after Arline died.

"Feynman — a scientist perhaps uncommonly romantic yet resolutely rational and unsentimental in his reverence for the indomitable laws of physics that tend toward decay — penned a remarkable letter to a physical nonentity that was, for the future Nobel-winning physicist, the locus of an irrepressible metaphysical reality".

If nothing else, this letter encourages us to understand that incredible scientists aren't machines. It's easy to visualize a lone genius contemplating our world without looking into life's details.

We discover here that this belief is misconstrued through his letter.

It's okay to be sad, it's ok to grieve, and it's okay to do things that don't make sense to feel better. It's ok. Feynman admits that he thought "there was no sense to writing."
