Instructor : Charles Myles Lee, EunMo Outline of the talk The Harmonic Oscillator Nonlinear Oscillations Nonlinear Resonance Parametric Resonance The Harmonic Oscillator The amplitude of oscillations depend on the driving frequency. It has its maximum when the driving frequency matches the eigenfrequency. This phenomenon is called resonance 2.

He invigorated undergraduate physics education at Cal Tech, where his years of lectures were edited & collected into the 3-volume book The Feynman Lectures on Physics, which has become an inspiration for students of physics ever since. He also published a number of popularizations of physics, including QED: The Strange Theory of Light and Matter.

Nuclear PhysicsFission and Fusion. Nuclear energy is produced in two different ways. Fission: Large nuclei are split to release energy. Is how we get a lot of our energy from (Nuclear Fission Reactors) #1 source of energy = fossil fuels (coal). #2 source of energy = nuclear fission (memory aid: i in Fission = i fall to pieces) Fusion:
