Chemistry, 2nd Edition (Course No. 1012) is a newly updated and expanded version of High School Level—Chemistry (Course No. 111). This revised edition features six new lectures, enhanced visual elements, a new workbook with more than 400 problems and worked-out solutions, and more.

Intended as a precursor to Algebra I, this course introduces math’s basic concepts, as well as the fundamentals that underlie some of its more complicated areas. Let Professor Siegel instruct your student with his knack for explaining both the how and why of key mathematical ideas and techniques, including whole numbers, fractions, decimals, percents, integers, exponents, square roots, and measurements.

Chaos theory—the study of the behavior of sensitive systems over time—affects nearly every field of human knowledge, from the arts to zoology. Journey with Cornell University Professor Steven Strogatz to the heart of this revolutionary field and discover new ways to think about the world. From the surprising tale of how chaos theory was discovered, to the ways it can help us solve mysteries like the nature of consciousness, Chaos gives you a solid introduction to a fascinating discipline that has more to do with your life than you may realize.

In Particle Physics for Non-Physicists: A Tour of the Microcosmos, Professor Steven Pollock translates the language of the remarkable science that, in only 100 years, has unlocked the secrets of the basic forces of nature. You will become familiar with the fundamental particles that make up all matter, from the tiniest microbe to the sun and stars. You will also learn the "rules of the game"—the forces the particles feel and the ways they interact—that underlie the workings of the universe.

Everything we can see with our eyes and with powerful instruments—everything we think of as atom-based matter—is only 5 percent of what we know exists. The rest of the contents of the cosmos is invisible to our current methods of detection—but something out there is holding galaxies and galaxy clusters together, and something else is causing space itself to fly apart. These invisible components are dark matter and dark energy, the most eagerly studied subjects in astronomy and particle physics today.

Professor Noggle's lectures on geometry are exceptionally clear and well organized. He has an evident love for the topic, and a real gift for conveying the elegance and precision of geometric concepts and demonstrations. You will learn how geometrical concepts link new theorems and ideas to previous ones. This helps you see geometry as a unified body of knowledge whose concepts build upon one another.

Albert Einstein: Physicist, Philosopher, Humanitarian examines Einstein's revolutionary innovations in physics, his philosophical reflections on the methods and foundations of science, and his public efforts championing a variety of social causes. By the end of these 24 lectures, you'll have become better acquainted with the whole Einstein—his scientific ideas, his personal philosophies, his thought processes, and his impact on both his time and ours.

The Virtual Tutor Series of training DVD's has assisted people in learning and using ArchiCAD efficiently since Version 6.5. six editions and nearly a decade later the tutorial disks have grown from CD's to DVD's. Tips on how to use the tools, create documentation, render scenes, file management, explanations of environments and general tips all go into each Virtual Tutor.
