Naturwissenschaften – Erste Ausgabe. - DSB VIII, 261 - 262 - Leslies Hauptwerk legte mehrere grundlegende Gesetze der Wärmestrahlung fest: dass die Emissions- und Absorptionsfähigkeit jeder Oberfläche gleich sind, dass die Emissionsfähigkeit einer Oberfläche mit zunehmender Reflektivität ansteigt und dass die Intensität der von einer Oberfläche abgestrahlten Wärme proportional zum Sinus des Winkels der Strahlen zur Oberfläche ist. Das Buch spielte zudem eine wichtige Rolle in der Debatte zu Beginn des 19. Jahrhunderts darüber, ob Wärme eine Form der Materie oder eine Bewegungsart sei. Leslies Experimente zeigten, dass Wärme im Gegensatz zu Licht nicht direkt durch transparente Festkörper übertragen wurde. In Kapitel 19 beschreibt Leslie einige der Geräte, insbesondere ein Photometer, die er bei seinen Experimenten verwendete. - Teils etwas braun- bzw. stockfleckig.

Natural Sciences – First edition. - Leslie's magnum opus established several fundamental laws of thermal radiation: that the emissivity and absorptivity of any surface are equal, that the emissivity of a surface increases with increasing reflectivity, and that the intensity of heat radiated by a surface is proportional to the sine of the angle of the rays to the surface. The book also played an important role in the early 19th-century debate over whether heat was a form of matter or a mode of motion. Leslie's experiments showed that, unlike light, heat was not transmitted directly through transparent solids. In Chapter 19, Leslie describes some of the instruments-in particular, a photometer-that he used in his experiments. Half leather with spine label (worn, joints torn, capital letters with missing parts). - Some pages are slightly browned or have stains.
