Relativity and quantum physics touch the very basis of physical reality, altering commonsense notions of space and time, cause and effect. Both have reputations for complexity, but the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. The essence of relativity in a single sentence: The laws of physics are the same for all observers in uniform motion. Relativity and quantum physics are the gateway...

Dr. Carroll explains the subject of dark matter and dark energy in 24 lectures. He explains why scientists believe we live in a smooth, expanding universe that originated in a hot, dense state called the Big Bang. He describes the features of the infant universe that led to the large-scale structure we observe today. He takes you through the standard model of particle physics and shows how it provides the framework for understanding the interaction...

Professor Sargent begins the course with a series of lectures that orient you to the nanoscale and then cover some of the most significant developments in electronics that have made use of nanotechnology in computers, communications, and imaging. Then Professor Kelley delivers a sequence of lectures on her specialty: the biological applications of nanotechnology, especially to medicine. Since the biology of life happens at the nanoscalein proteins...

In 24 clear and easily accessible lectures, Professor Wolfson combines his academic expertise and his lifelong vocation as an electronics hobbyist to examine how these remarkable devices work, bypassing much of the higher mathematics without sacrificing functional and theoretical understanding. Whether you're an aspiring engineer, an enthusiastic tinkerer, or simply intellectually curious, this course will demystify the behavior and inner circuitry...
