When Mae Holland is hired to work for the Circle, the world's most powerful internet company, she feels she's been given the opportunity of a lifetime. The Circle, run out of a sprawling California campus, links users' personal emails, social media, banking, and purchasing with their universal operating...

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 creator of the popular webcomic "xkcd" uses line drawings and common words to provide simple explanations for how things work, including microwaves, bridges, tectonic plates, the solar system, the periodic table, helicopters, and other essential concepts.

This program covers the important topic of conservation of energy (part 1) in simple harmonic motion in Physics. We begin by discussing how in a perfect system energy is neither created nor destroyed. As the object swings, the energy is continually transferred from kinetic to potential forms and vice versa. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis...

This program covers the important topic of standing waves and resonance (part 2) in Physics. We begin by discussing how waves can be made to reflect off of an object and interfere in the opposite direction to the original wave leading to a standing wave. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills...

This program covers the important topic of heat engines and the second law of thermodynamics in Physics. We begin by discussing the theory, which involves how useful work can be done by engines which use expansion or hot gases to move a piston. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual...

Pound for pound, the supercell is the most powerful thunderstorm on Earth. Explore the mechanics of this system, which produces the strongest straight-line winds, the most violent tornadoes, and the largest hail. Close by looking at the formation of a record-breaking hailstone weighing almost two pounds!

Relativity was incomplete until Einstein formulated a general theory of relativity that incorporated gravity. See how this breakthrough demolished the age-old idea of gravity as a force, replacing it with the concept of warped spacetime, leading to strange predictions such as black holes..

Traditional attempts to understand the world assumed that it was regular, simple, periodic, and predictable. But nature surprised scientists, giving them a richer picture of reality through chaos theory, which includes fractal structures. Learn how chaos is not randomness but a previously unimagined complexity within the universe..

Continue your investigation of social reality by looking at the concept of progress. Social optimists and pessimists alike believe that society is progressing, but they see different causes. Evaluate their theories, and explore the idea that Western culture is doomed to collapse under its own weight..
