This module combines four elements of modern physics as follows:
Special Relativity
Lecturers: Professor C. Patterson
Duration: Hilary Term, 12 lectures
Description:
Frames of reference and relativity principles. The Michelson-Morley experiment. Einstein's postulates, simultaneity, the Lorentz transformations, the Fitzgerald-Lorentz contraction, time dilation, transformation of velocities. Relativistic dynamics - mass, energy and momentum.
Quantum Physics
Lecturers: Professor J. Pethica
Duration: Hilary Term, 12 lectures
Description:
Origins of quantum physics. Black body radiation. Photoelectric effect. Compton Effect. De Broglie's Postulate. The Uncertainty Principle. Atomic spectra. Bohr model of the atom. Correspondence Principle. Steady-state Schrödinger equation. Particle in an infinite square well. Finite square well. Simple harmonic oscillator. Particle at potential step. Tunnelling through a barrier. Quantum theory of Hydrogen atom.
Nuclear Physics
Lecturers: Professor E.C. Finch
Duration: Hilary Term, 12 lectures
Description:
Scattering. Cross-sections. Rutherford scattering. Nuclear force. Nuclear binding. Nuclear masses. Mass defect. Mass dependence of binding energy per nucleon. Beta decay. Electron, positron emission. Electron capture. Decay chains. Alpha decay. Heavy element decay chains. Barrier penetration mechanism. Gamma decay. Radioactive decay law. Analysis of parent-daughter activity relationships. Nuclear fission. Liquid drop model. Fission products. Induced fission. Nuclear reactors. Neutron moderation. Control and delayed neutrons. Reactor types. Environmental and other concerns. Fuel cycle. Nuclear fusion. Fusion reactors.
Observing the Universe
Lecturers: Professor B. Espey
Duration: Hilary Term, 12 lectures
Description:
Basic astronomical definitions. The Earth and Moon in space; co-ordinate systems. The Sun and stars, basic stellar information (distance, luminosity, life cycle). The structure of our Galaxy and other galaxies, variable and exploding stars as 'standard candles' for measuring the distance of galaxies. Our place in the Universe; the origin and fate of the Universe.
