Course 3, Session 2

When we look at the world around us, we see motion. If you were to examine a still object close enough, you would see that it too is constantly in motion. Sight is the most predominant sensory perception of most animals. If you can see something, its detection is keener in one’s mind than if it were sensed otherwise. Light is the basis of visual detection and warmth. (Heat is a form of electromagnetic energy.) If there were no heat, there would be no life or molecules. Since heat is light when at a certain wavelength, light is the most fundamental and important component and factor in allowing life to exist. Since light allows the motion of material phenomena, then there must be a relationship between the existence of light and the motion of objects.

Earlier, we discussed how light is created. An atom exists as a set of nucleon(s) that are surrounded by electrons. Things tend to take the path of least resistance. This is because phenomena tends to work at coming to rest or at least “trying” to expel the least amount of energy that it can. Look at people, they tend to try to do things in the easiest manner that they can. This is because when a person or a thing conserves energy, it has less of a tendency to be disorganized and thus this person or thing finds more stability. If something is more stable, then it is in less of a state of disorder. Disorder is entropy. Although entropy allows for important changes, such as melting, it also causes things to eventually fly apart. Look at your room. The more disorder it’s in, the more things get scattered. Life requires order, since it’s composed of a general organization of certain molecules. This is why life tends to try to stay at rest, and thus find more stability. Other material phenomena acts the same general way, since stability and thus the condition of staying at rest helps the phenomena. So, these obey the same general rule that of previously described. So when an electron finds a chance to exist with less energy in such a manner that it does not have to meet up with any undo resistance then, naturally, that electron will do what it takes to go to the general location that provides it with the opportunity to be more at rest. This entails an electron dropping an energy level in order to then have less energy, although maintaining mass at least for the most part. At this point, it releases that energy, since everything goes somewhere. This energy organizes in order to be a specific thing and is called a photon. Photons in the surrounding area come together in whatever number accompanies the direction in which these are propagated. Remember, the basic energy and wavelength of photons are discrete units. Depending on the combination of photons that form a single wavelength of a given type of light, that light could be whatever form of electromagnetic energy this would describe. Since light is key to existence, and is also a key residue of it, the very nature of light’s movement is key to the motion of all other physical phenomena.
