"The Secrets of Mental Math, his exciting new 12-lecture course, guides you through all the essential skills, tips, and tricks for improving and enhancing your ability to solve a range of mathematical problems right in your head"--The Great Courses website.

Course covers the making of our planet from the Big Bang, to the formation of the solar system, to the subsequent evolution of Earth. Travel to the center of our planet and out again, charting the geologic forces that churn beneath our feet to push the continents and seafloor.

Thirty six half-hour lectures that cover all the major topics of a full-year calculus course in high school at the College Board Advanced Placement AB level or a first-semester course in college. Includes crystal-clear explanations of the beautiful ideas of calculus, frequent study tips, pitfalls to avoid, and hundreds of examples and practice problems that are specifically designed to explain and reinforce major concepts. -- Publisher.

520 Everyone loves to see the beauty of the star-studded night sky, but how many of us understand what makes stars shine, where Saturn's rings come from, or why galaxies have their distinctive shapes. Observational astronomy excels at cataloging celestial objects, but it takes a more rigorous discipline to come up with physical explanations for them. That field is astrophysics, which uses the laws of physics to investigate everything beyond Earth....

The world of mathematics contains some of the greatest ideas of humankind--ideas comparable to the works of Shakespeare, Plato, and Michelangelo. These mathematical ideas can add texture, beauty, and wonder to your life, without being a mathematician! This course explores the fourth dimension, coincidences, fractals, aesthetics, the allure of number, geometry, and how great mathematical ideas arise, along with learning to think abstractly, to grasp...

"Understanding genetics is like sitting down to work a massive puzzle. With each piece you examine, think through, and solve, you glean a new and amazing insight into humanity. Put several pieces together, and you can treat or cure a disease, save a developing fetus from a fatal birth defect, catch a criminal, or reunite a family...Each lecture begins with a helpful story that illustrates the importance of genetics. The course explicitly outlines...

Discusses discrete mathematics, a subject that is off the beaten track that most of us followed in school but that has vital applications in computer science, cryptography, engineering, and problem solving of all types. Focusing on three of discrete mathematics most important fields (combinatorics, number theory and graph theory), presents a selection of problems, proofs, and applications.

"This course takes you to the world's most spectacular geological wonders, explains the forces that have formed them, and tells you the stories that have grown up around them."--page 1 of course guidebook.

You live with it 24 hours a day, but how well do you really know it? This course is an owner's manual to a remarkably complex, resilient, and fascinating structure: the human body. Using detailed color illustrations, life-sized models, and, even a video shot during surgery, this course examines the major systems of the body, explaining exactly how things work and why they sometimes don't. Each lecture concentrates on a particular organ or organ...
