Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.)
This is the second part (chapters 13-24) of a pdf textbook for a one-year introductory physics course. The text was developed out of an alternate beginning physics course at New Mexico Tech designed for students with a strong interest in physics. A broad outline of the text is as follows: Newton's Law of Gravitation; Forces in Relativity; Electromagnetic Forces; Generation of Electromagnetic Fields; Capacitors, Inductors, and Resistors; Measuring the Very Small; Atoms; The Standard Mode; Atomic Nuclei; Heat, Temperature, and Friction; Entropy, The Ideal Gas and Heat Engines.
How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.
Is it a tumor? Magnetic Resonance Imaging (MRI) can tell. Your head is full of tiny radio transmitters (the nuclear spins of the hydrogen nuclei of your water molecules). In an MRI unit, these little radios can be made to broadcast their positions, giving a detailed picture of the inside of your head.
