Reading Journal 1 - Atoms in Motion

This chapter of Six Easy Pieces discusses everything is made from atoms. It emphasizes this theories importance as well. What makes the atomic theory so important? Why would it be the “only one sentence passed on to the next generations of creature?” Why not start at more elementary particles like electrons, photons, protons, neutrons, etc…? Feynman talks about the structures that atoms form in solids and the errors in illustrating atoms. Illustrations of atoms fail to show how atoms never stop moving. Even at absolute zero, the atom still has to jiggle and vibrate. If moving uses energy, then wouldn’t the idea that all atoms are constantly moving mean that everything needs a constant supply of energy? If so, what is the source of energy? Would it be the repulsion and attraction of protons and electrons? Feynman does say that these illustrations are beneficial in their ability to show angles. Wouldn’t you be in able to see the 3rd dimension of angles; making the illustration a failure at demonstrating angles? He also discusses how water evaporates and the equilibrium that is established between the air and the liquid. If by blowing these air away alters the equilibrium to push more liquid into water vapor, couldn’t you cool mass amounts of liquid with a fan blowing the top of it? There is also a brief discussion on the task assigned to chemists in naming compounds. Feynman clearly believes that physics is the superior science, however I believe that chemistry is just a different, equal form of science. It does not require less brainpower to do chemistry; it is simply a different skill. If that is the case then what about the other forms of science (biology, engineering, astrology, psychology, etc…), are they also inferior to physics because they require different skills?
