BASIC PHYSICS

  • Nucleus consist of two kinds of particles, protons and neutrons, almost of the same weight and very heavy.
  • The protons are electrically positive charged and the neutrons are neutral.
  • An atom has a diameter of about 10^-8 cm. The nucleus has a diameter of about 10^-13 cm.
  • If we have an atom with six protons inside its nucleus, and this is surrounded by six electrons , this would be atom number six in the chemical table, and it is called carbon.
  • So the chemical properties of a substance depend only on the number of electrons.

"A good idea should be like a girl's skirt; long enough to cover the subject and short enough to create interest."

Richard Phillips Feynman (May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.
