The old Copenhagen interpretation of quantum mechanics associated with Niels Bohr is giving way to a more profoud interpretation based on the idea of quantum entanglement. Entanglement not only replaces the obsolete notion of the collapse of wave function but it is also the basis for Bell's famous theorem, the new paradigm of quantum computing, and finally the widely discussed "Many Worlds" interpretation of quantum mechanics of...more

This course is a first-semester freshman physics class in Newtonian Mechanics, Fluid Mechanics, and Kinetic Gas Theory. In addition to the basic concepts a variety of interesting topics are covered in this course: Binary Stars, Neutron Stars, Black Holes, Resonance Phenomena, Musical Instruments, Stellar Collapse, Supernovae, Astronomical observations from very high flying balloons (lecture 35), and you will be allowed a peek into the...more

In this lecture, Professor Donald Kagan explores the earliest history of Greek civilization. He demonstrates how small agricultural enclaves eventually turned into great cities of power and wealth in the Bronze Age, taking as his examples first Minoan Crete and then Mycenaean Greece. He also argues that these civilizations were closely related to the great monarchies of the ancient Near East. He points out that the Mycenaean age...more

This lecture focuses on George Washington and the combined qualities that made him a key figure in Revolutionary America, arguing that the most crucial reason for his success as a national leader was that he proved repeatedly that he could be trusted with power - a vital quality in a nation fearful of the collapse of republican governance at the hands of a tyrant.

The disintegration of the Soviet Union resulted from a number of different factors. Three important ones are nationalism among Soviet satellite states, democratic opposition movements, and economic crisis. Along with these elements, the role of Mikhail Gorbachev should not be discounted. Although his attempt to reform communism was rejected, his reformist positions as Soviet premier helped open the way for full-fledged political...more

Doppler Effect, Binary Stars, Neutron Stars and Black Holes. Doppler shift is introduced with sound waves, then extended to electromagnetic waves (radiation). The Doppler shift of stellar spectral lines and/or pulsar frequencies provides a measure of the line-of-sight (so-called radial) velocity of the source relative to the observer. Combined with Newton's law of universal gravitation, this can lead to the orbital parameters and the mass...more
