Description
Quantum mechanics gives us a picture of the world so radically counterintuitive that it has changed our perspective on reality itself. In Quantum Mechanics: The Physics of the Microscopic World, award-winning Professor Benjamin Schumacher gives you the logical tools to grasp the paradoxes and astonishing insights of this field.

The study of motion is not all there is to physics. By the 18th century, scientists were delving into the relationship between the two phenomena. Today, electromagnetism is known to be responsible for the chemical interactions of atoms and molecules and all of modern electronic technology.

Description
One of the most attractive ideas for physicists searching for a theory of everything is supersymmetry, which treats force- and matter-carrying particles as interchangeable. Explore major problems that supersymmetry solves and the shortcomings that convince some scientists that perhaps some other ideas must also be considered.

Description
Along with relativity, Einstein's major contributions to physics include his proof that light is made up of discrete quanta, an insight that led to the quantum revolution. Retrace his route to this key discovery. As with relativity, his genius was to break out of the classical mode of thinking about light and matter, going wherever experiment, logic, and mathematics led him.

The uncopyability of quantum information raises the possibility of quantum cryptography - an absolutely secure method for transmitting a coded message. This lecture tells how to do it, noting that a handful of banks and government agencies already use quantum cryptography to ensure the security of their most secret data.

Description
Taught by physicist Dan Hooper of Fermilab and the University of Chicago, this course focuses on Einstein’s mistakes as a window into his theory-building technique. He was spectacularly effective with relativity and early quantum mechanics, but he also made some missteps by doubting some of the staple concepts of today’s physics, including black holes, the big bang, and the uncertainty principle.

Take a whirlwind tour of nuclear physics, getting a glimpse of the rich array of topics and concepts you will cover in this course. Professor Weinstein explains the constituents of the nucleus; what holds the nucleus together, its role in determining atomic identity; and the nature of isotopes. He introduces two key tools: the periodic table of elements and the table of nuclides.

See how the strong and electromagnetic forces shape the nuclei of all atoms. Focus on the curve of binding energy, which explains why heavy nuclei are prone to fission, releasing energy in the process, while light nuclei release energy by fusing. Visit some classroom lab equipment to explore the principles that govern particle accelerators, which are used to probe the structure of nuclear matter.

Continue exploring time by winding back the clock. Was there a beginning to time? Einstein’s initial equations of general relativity predicted a dynamic universe, one that might have expanded from an initial moment. Einstein discarded this idea, but since then evidence has mounted for a “Big Bang.” Is it sensible to ask what caused the Big Bang and what happened before?

Radiation terrifies many of us, but how scared should we be? Probe the difference between ionizing and non-ionizing radiation, focusing on what high-energy emissions do to DNA. Consider a host of radiation sources - from the innocuous, such as cell phones and power lines, to nuclear explosions and dirty bombs. Finally, learn what to do if you are ever exposed to nuclear fallout.
