HELMHOLTZ, H[ermann von]
I. Ueber die Wechselwirkung der Naturkräfte und die darauf bezüglichen neuesten Ermittelungen der Physik. Königsberg: Gräfe & Unzer, 1854. 8vo. Contemporary cloth-backed marbled boards.
Second edition (printed the same year as the first). This extremely rare paper (On the Interaction of Natural Forces, and Recent Physical Discoveries Bearing on the Same), considered Helmholtz’s most brilliant scientific lecture, was given in direct response to Clausius’ assault of his landmark work, Über die Erhaltung der Kraft (On the Conservation of Energy). In a masterly exposition intelligible to all, he communicates his theory of the sun’s heat based on his first law of thermodynamics. $ 750.00.
