This course begins with the challenge of defining intelligence for scientific study. Savants show one aspect of specific mental abilities, but there is also strong evidence that all mental abilities have a common general factor of intelligence-- called "g". Measuring "g" and other factors of intellegence depends mostly on IQ-type tests, which the course will explain, including what these tests do and do not measure.

Calculus is the greatest mathematical breakthrough since the pioneering discoveries of the ancient Greeks. Without it, there would be no spaceflight, skyscrapers, jet planes, economic modeling, or accurate weather forecasting. One of the most powerful problem solving tools ever invented, calculus is a skill that can be learned. Its techniques are used to analyze situations involving change, to calculate optimum values, and to measure complex shapes....

"Learn how to reduce the threat of misinformation from local, national, and international sources and ensure the validity of the information you share."--Container

Hollywood has gone to elaborate lengths to recreate the violence and mayhem of ancient warfare in movies, but what were ancient battles really like? What weapons, tactics, armor, training, and logistics were used? What were the crucial factors that could turn the tide of battle, giving one side victory and consigning the other to slaughter, capture, or, at best, escape to fight another day? These lectures examine some of the most notable battles fought...

"Calculus II is the payoff for mastering Calculus I. This second course in the calculus sequence introduces you to exciting new techniques and applications of one of the most powerful mathematical tools ever invented. Equipped with the skills of Calculus II, you can solve a wide array of problems in the physical, biological, and social sciences, engineering, economics, and other areas. Success at Calculus II also gives you a solid foundation for the...

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...

Explores the continuous series of brutal surprises and shocks that the first example of a "total war" brought, a conflict not limited to armies, but pitting entire societies against each other in mortal struggle. An estimated 70 million men were mobilized and approximately 9 million died. The civilizational impact of an industrial slaughter on this scale was so significant that World War I set the 20th century on its violent course, culminating in...

A former award-winning middle school science teacher provides tips on study skills for high school students to improve their academic achievement. Parent participation is also discussed.
