You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the universe, and none is destroyed. You want your mother to know that all your energy … every wave of every particle that was her beloved child remains with her in this world…. There may be a few fanning themselves with their programs as he says it. And he will tell them that the warmth that flowed through you in life is still here, still part of all that we are, even as we who mourn continue the heat of our own lives. And you’ll want the physicist to explain to those who loved you that they need not have faith; indeed, they should not have faith…. The science is sound…. According to the law of the conservation of energy, not a bit of you is gone; you’re just less orderly. Amen.
