Fayman was born in Manhattan in 1918, who had a successful career in physics inspired by his father. His father instilled him to ask questions to have unorthodox thinking, while his mother gave him a never-ending sense of humor. He went to MIT, but later graduated at Princeton; when at Princeton he was encouraged by a fellow physicist at Princeton, Robin Wilson, to take part in the Manhattan project which he later participated in. During this time he visited his hospitalized wife on the weekends until her death in 1945. After the success of the project he worked as a professor at Cornell University, which he was unhappy at, leading to his career at the Institute for Advanced Study at Princeton where Einstein was working at the time. He accomplished some of his best works here such as weak decay, quantum electrodynamics, and physics of the superfluidity of supercooled liquid helium; he also created diagrams which aided in calculating and conceptualizing interactions between particles, named after himself. From the 1950s and onward he was a professor of physics at Caltech where he was tasked with teaching undergraduates; with three years of educating undergraduates via lectures, which led to fame, he won the Orested medal for teaching, for which he was always proud of. He wrote many books and was one of the first physicists to realize the possibility of quantum computers. He was married twice after the death of his first, once to a quickly failed marriage and another who he had a child with, adopted another, and stayed with until death. He had an instance of cancer which quickly receded with surgery, which later returned a year later that was actually worsened by surgery; he died on the 15th of February in 1988.

The atomic hypothesis, is the hypothesis that "all things are made of atoms-- little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one another". Atoms are in all existing things, and if you look at anything close enough there will be particles in either a static or unfixed state; this depends on the state of matter such as solids will have their vibrating particles barely noticeable and in fixed positions, gases will have their few particles moving at quick rate, while liquids have their particles moving little in comparison to gas, but are not in fixed positions such as solids. If the density is low enough between particles that there is very little, such as in gases, the pressure is proportional to the density. Temperature directly relates to the speed of the moving particles. With high temperatures, the particles become so jittery and dense that they will eventually be of the gas state, while with very low temperatures they will slow down and eventually become in fixed positions such as the solid state. When the temperatures are high the atoms will hit each other harder due to their increased speeds; this also causes more occurrences in which they hit which will, in turn, result to increased pressures, which increases the speed as from each collision the speed will increase. Due to this knowledge, we can conclude that all atoms in a select area will and have picked up speed; this means that during compression the temperature increases and during expansion the temperature decreases. As said before, in the solid state particles are apparently static (although they are indeed in motion), the array in which they are fixed is named the crystalline array. Most substances (bar type metal and water) expand when melting and sometimes apparently shrinks, such as the case with ice melting. The solid is melting when the temperature
