RESOURCES

·         WWW resources:

·        A useful internet guide to many ideas of modern physics is Physics 2000.

·        Read about Newton and Maxwell, chaps who laid the foundations of Classical Physics (Mechanics and Electromagnetism).

·        Planetary features that refute geocentric model, Jupiter, Venus, Moon.

·        The medical technique of MRI (Magnetic Resonance Imaging) uses solenoid magnetic fields and electromagnetic radio waves to detect water content in the body.

·        CT (Computerized Tomography) scans use 3-dimensional arrangements of X-rays to reconstruct images for medical diagnosis.

·        Read about Einstein, the creator of Relativity.

·        Light clocks at rest and in relative motion

·        Particle accelerators move elementary particles close to the speed of light. An old one (0.99c) and the latest one (0.99999c) at CERN laboratory in Geneva.

·        Aircraft routes follow geodesics, the shortest path between two points. This is not a straight line because the Earth is not flat (even in Kansas). 

·        Gravity bends the path of light, producing gravitational lensing of galaxies and black holes

·        Our galaxy, the Milky Way.

·        The Hubble space telescope has verified many of the predictions of General Relativity in recent years.

·        Microwave radiation from the Big Bang fills the expanding universe.

·        Quantum Mechanics is so weird, it took many scientists to piece together the model – Planck, Einstein, Heisenberg, Bohr, Born, Schrodinger, and more..

·        Two sources of waves will produce an interference pattern which can also be realized as probability of particle detection.

·        Microscopes that use electrons instead of light can see smaller things.

·        Electron `waves’ imaged inside an atomic corral

·        The line spectra that exist within the spectrum of colours due to absorption of special wavelengths by atoms.

·        Development of the LASER as an example of a cooperative Quantum phenomenon.

·        Nuclear reactions combine Quantum Mechanics & Relativity to release enormous energy, such as in `atomic bombs’, Crossroads Baker (fission), Tsar Bomb (fusion).

·        Michael Frayn’s play Copenhagen, explores philosophical and political consequences of quantum mechanics in World War II.

·        Unsolved Mysteries of Physics beyond the Standard Model (final PowerPoint lecture)
