In Verne's book “From The Earth To The Moon”,characters reached the moon in a capsule shot from shot from an enormous cannon. Although this idea would not work, Tsiolkovsky proved-in theory- that rockets could generate enough force to reach outer space. He Also suggested the use of liquid rocket fuel to increase a rocket's range. For his vision and careful work, Tsiolkovsky is known as the father of rocket theory.

Using the word TEMPERATURE instead of of words such as COOL or WARM avoids confusion. Scientifically, TEMPERATURE is a measure of the average kinetic energy of the particles in an object.
