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 vibration, every Btu of heat, every wave of every particle that was her beloved child remains with her in this world. You want the physicist to tell your weeping father that amid energies of the cosmos, you gave as good as you got.And at one point you'd hope that the physicist would step down from the pulpit and walk to your brokenhearted spouse there in the pew and tell him that all the photons that ever bounced off your face, all the particles whose paths were interrupted by your smile, by the touch of your hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by you. And as your widow rocks in the arms of a loving family, may the physicist let her know that all the photons that bounced from you were gathered in the particle detectors that are her eyes, that those photons created within her constellations of electromagnetically charged neurons whose energy will go on forever.And the physicist will remind the congregation of how much of all our energy is given off as heat. 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. Let them know that they can measure, that scientists have measured precisely the conservation of energy and found it accurate, verifiable and consistent across space and time. You can hope your family will examine the evidence and satisfy themselves that the science is sound and that they'll be comforted to know your energy's still around. According to the law of the conservation of energy, not a bit of you is gone; you're just less orderly. Amen.
And when I look around the apartment where I now am,—when I see Charlotte’s apparel lying before me, and Albert’s writings, and all those articles of furniture which are so familiar to me, even to the very inkstand which I am using,—when I think what I am to this family—everything. My friends esteem me; I often contribute to their happiness, and my heart seems as if it could not beat without them; and yet—if I were to die, if I were to be summoned from the midst of this circle, would they feel—or how long would they feel—the void which my loss would make in their existence? How long! Yes, such is the frailty of man, that even there, where he has the greatest consciousness of his own being, where he makes the strongest and most forcible impression, even in the memory, in the heart of his beloved, there also he must perish,—vanish,—and that quickly.I could tear open my bosom with vexation to think how little we are capable of influencing the feelings of each other. No one can communicate to me those sensations of love, joy, rapture, and delight which I do not naturally possess; and though my heart may glow with the most lively affection, I cannot make the happiness of one in whom the same warmth is not inherent.Sometimes I don’t understand how another can love her, is allowed to love her, since I love her so completely myself, so intensely, so fully, grasp nothing, know nothing, have nothing but her!I possess so much, but my love for her absorbs it all. I possess so much, but without her I have nothing.One hundred times have I been on the point of embracing her. Heavens! what a torment it is to see so much loveliness passing and repassing before us, and yet not dare to lay hold of it! And laying hold is the most natural of human instincts. Do not children touch everything they see? And I!Witness, Heaven, how often I lie down in my bed with a wish, and even a hope, that I may never awaken again! And in the morning, when I open my eyes, I behold the sun once more, and am wretched. If I were whimsical, I might blame the weather, or an acquaintance, or some personal disappointment, for my discontented mind; and then this insupportable load of trouble would not rest entirely upon myself. But, alas! I feel it too sadly; I am alone the cause of my own woe, am I not? Truly, my own bosom contains the source of all my pleasure. Am I not the same being who once enjoyed an excess of happiness, who at every step saw paradise open before him, and whose heart was ever expanded towards the whole world? And this heart is now dead; no sentiment can revive it. My eyes are dry; and my senses, no more refreshed by the influence of soft tears, wither and consume my brain. I suffer much, for I have lost the only charm of life: that active, sacred power which created worlds around me,—it is no more. When I look from my window at the distant hills, and behold the morning sun breaking through the mists, and illuminating the country around, which is still wrapped in silence, whilst the soft stream winds gently through the willows, which have shed their leaves; when glorious Nature displays all her beauties before me, and her wondrous prospects are ineffectual to extract one tear of joy from my withered heart,—I feel that in such a moment I stand like a reprobate before heaven, hardened, insensible, and unmoved. Oftentimes do I then bend my knee to the earth, and implore God for the blessing of tears, as the desponding labourer in some scorching climate prays for the dews of heaven to moisten his parched corn.
