Lasers are essential to an incredibly large number of applications. Today, they are used in bar code readers, compact discs, medicine, communications, sensors, materials processing, computer printers, data processing, 3D-imaging, spectroscopy, navigation, non-destructive testing, chemical processing, color copiers, laser "shows", and in the military. There is hardly a field untouched by the laser. But what exactly is so unique about lasers...more
This course introduces the fundamentals of technology entrepreneurship, pioneered in Silicon Valley and now influencing other locations around the world. You will learn the process used by technology entrepreneurs to start companies. It involves taking a technology idea and finding a high-potential commercial opportunity, gathering resources such as talent and capital, figuring out how to sell and market the idea, and managing rapid growth...more
This course is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first- an...more
This course provides a thorough introduction to the principles and methods of physics for students who have good preparation in physics and mathematics. Emphasis is placed on problem solving and quantitative reasoning. This course covers Newtonian mechanics, special relativity, gravitation, thermodynamics, and waves.
The most basic of the math playlists. Start here if you have very little background in math fundamentals (or just want to make sure you do). After watching this playlist, you should be ready for the pre-algebra playlist.
This is a continuation of Fundamentals of Physics, I (PHYS 200), 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. Course Structure: 75 minute lectures, twice per week
Capitalism: Success, Crisis and Reform (PLSC 270) In this final lecture of the semester, Professor Rae gives a summary of major themes, thinkers, and cases covered in the course. He begins by reviewing some foundational ideas, including Adam Smith's invisible hand, Marxist historicism, Malthusian economics, and Schumpeter's notion of creative destruction. Professor Rae also reviews the importance to capitalism of the modern nation state, ...more
Fundamentals of Physics, II (PHYS 201) The double slit experiment, which implies the end of Newtonian Mechanics is described. The de Broglie relation between wavelength and momentum is deduced from experiment for photons and electrons. The photoelectric effect and Compton scattering, which provided experimental support for Einstein's photon theory of light are reviewed. The wave function is introduced along with the probability interpreta...more
Professor Summers, former U. S. Treasury Secretary and former President of Harvard University, in this the first of two lectures in honor of former Yale Professor and Council of Economic Advisors chairman Arthur Okun, offers thoughts on the role of monetary policy in economic fluctuations, past and present. In the "Okun period," ending about when Okun died in 1980, the monetary authorities were very much involved in actually creating econo...more
Fundamentals of Physics, II (PHYS 201) Lecture begins with a detailed review of the double slit experiment with electrons. The fate of an electron traversing the double slit is determined by a wave putting an end to Newtonian mechanics. The momentum and position of an electron cannot both be totally known simultaneously. The wave function is used to describe a probability density function for an electron. Heuristic arguments are given for...more
Fundamentals of Physics, II (PHYS 201) The physical meaning of the components of the wave equation and their applications are discussed. The power carried by the wave is derived. The fact that, unlike Newton's laws, Maxwell's equations are already consistent with relativity is discussed. The existence of magnetism is deduced from a thought experiment using relativity. 00:00 - Chapter 1. Recap—Solving Maxwell's Equations 18:18 - Chapter 2...more
