This is a continuation of the introductory course on the principles and methods of physics for students who have good preparation in physics and mathematics. This course covers electricity, magnetism, optics and quantum mechanics.
||01 – Electrostatics||The second half of the course begins with a discussion of electricity.||3/31/2011||Free||View in iTunes|
||02 - Electric Fields||The electric field is introduced as the mediator of electrostatic interactions: objects generate the field which permeates all of space, and charged objects in the field experience a force with magnitude proportional to their charge.||3/31/2011||Free||View in iTunes|
||03 - Gauss's Law I||The electric field is discussed in greater detail and field due an infinite line charge is computed.||3/31/2011||Free||View in iTunes|
||04 - Gauss's Law and Application to Conductors and Insulators||Lecture begins with a recap of Gauss's Law, its derivation, its limitation and its applications in deriving the electric field of several symmetric geometries—like the infinitely long wire.||3/31/2011||Free||View in iTunes|
||05 - The Electric Potential and Conservation of Energy||The law of conservation of energy is reviewed using examples drawn from Newtonian mechanics.||3/31/2011||Free||View in iTunes|
||06 - Capacitors||The electric potential is defined for the electric field.||3/31/2011||Free||View in iTunes|
||07 - Resistance||Lecture begins with a discussion of electric potential distribution in conductors.||3/31/2011||Free||View in iTunes|
||08 - Circuits and Magnetism I||After a description of more complicated electric circuits, the basic ideas underlying magnetism are discussed and the relationship between electrical charges and magnetic fields is explored.||3/31/2011||Free||View in iTunes|
||09 - Magnetism II||The mechanism by which electric currents produce a magnetic field (Law of Biot-Savart) is discussed in greater detail.||3/31/2011||Free||View in iTunes|
||10 - Ampere's Law||Ampere's law is used to find the magnetic field generated by currents in highly symmetric geometries like the infinitely long wire and the solenoid.||3/31/2011||Free||View in iTunes|
||11 - Lenz's and Faraday's Laws||The electric effect of a changing magnetic field is described using Faraday's Law.||4/1/2011||Free||View in iTunes|

||13 - LCR Circuits - AC Voltage||The mathematics underlying LCR circuit theory for AC currents is discussed.||4/1/2011||Free||View in iTunes|
||14 - Maxwell's Equations and Electromagnetic Waves I||Waves on a string are reviewed and the general solution to the wave equation is described.||4/1/2011||Free||View in iTunes|
||15 - Maxwell's Equations and Electromagnetic Waves II||The physical meaning of the components of the wave equation and their applications are discussed.||4/1/2011||Free||View in iTunes|
||16 - Ray or geometrical optics I||Geometric optics is discussed as an approximation to wave theory when the wavelength is very small compared to other lengths in the problem (such as the size of openings).||4/1/2011||Free||View in iTunes|

||21 - Quantum Mechanics III||The fact that the wave function provides the complete description of a particle's location and momentum is emphasized.||4/1/2011||Free||View in iTunes|
||22 - Quantum Mechanics IV: Measurement Theory, states of definite energy||It is shown how to extract the odds for getting different values of momentum from a generic wave function by writing it as a sum over functions of definite momentum.||4/1/2011||Free||View in iTunes|

Dr. Shankar Does It Again!
These lectures are related to his previous podcast: but this time it specializes on electromagentism, Maxwell's equations, wave mechanics,geometrical optics, and quantum mechanics. This podcast is a bit more complex than his lectures on elementary physics, since the math is unfamilar and the ideas are more abstract. But Professor Shankar does an excellent job to keep his students and podcast listeners intrigued by explaining complicated technical material to his class using simple English. I am optimistic that the next lectures that Yale University will improve their audio and video content. There are alternatives to this podcast that other universities offers, Walter Lewin and Leonard Susskind are terffic examples; but Shankar lectures are the best on iTunes and it should stay that way.
El contenido esta equilibrado y tiene mucha teoría básica que indiscutiblemente es imprescindible dejar pasar por alto. Es decir en el estudio de esta materia este es un instrumento mas de apoyo, el docente esta experimentado y refleja el contenido de cualquier material didáctico.
Recomiendo escuchar todo el contenido.
Duplicates missing video
This is an absolutely wonderful course, but despite Prof. Shankar's mellifluous voice, the video lectures seem to be audio only, and this is something you must really see. Download the version of this course with over 100 reviews instead please! I had the pleasure of taking this class while he was teaching it, and he really is a master at work. One of the reasons I became a physics teacher myself.
