Heat as a Force of Nature

Here on Earth, nature comes to life with the „fire” of the Sun—when the Sun’s light is received, heat is created to which, as Sadi Carnot said, „we must attribute the great movements which attract our attention here on Earth; it is to heat that we owe the agitations of the atmosphere, the rise of clouds, the fall of rain and other meteors, the currents of water which channel the surface of the globe, and of which man has thus far employed but a small portion. Even earthquakes and volcanic eruptions are the result of heat.
