The Teaching Company 是一家制造全美国顶级教授演讲录音及录影的公司。这些教授在华盛顿特区外的一家特别的工作室录制这些课程，然后课程被转制成磁带、CD、DVD、MPEG-4、MP3等格式出售。http://www.thegreatcourses.com/greatcourses.aspx The Teaching Company公司由Thomas M. Rollins先生创建于 1990 年，Thomas M. Rollins先生是美国前参议院委员会劳工及人力资源首席顾问，毕业于哈佛大学法学院。他在学习过程中注意到，使用录像带学习很有效率。于是他开始尝试发起一个政府项目，为公众制作磁带，但是由于法律的限制而无法实践。当他离任时，他抱着这个想法而开始搜寻顶级教授来制作课程，并且销售给公众。 截至2007年，这家公司共提供了超过260门课程，内容总时长达3000小时，跨越9门不同学科，分别是：商业学和经济学、艺术和音乐、古代史和中世纪史、近代史、文学和英语、哲学和思想史、宗教、科学和数学以及社会科学。 课程的目标是提供成人教育和终身教育，大学本科非专业的典型知识的教育；不仅如此，他还有一系列为高中生提供的课程。每一门课程都包括一些印有大纲、推荐书目、教授简介以及思考问题的补充小册子。此外，课程还提供全文的文本。 课程有多种不同的载体。起初，仅有磁带或是VHS录像带。后来，逐渐出现了CD及DVD版本，而现在也能下载到MP3版本。 2006年10月2日，这家公司被一家私募股权投资公司Brentwood Associates收购。

Imagine coming upon Earth as a traveler from another galaxy. It wouldn't take you long to discover Earth's fascinating variety. The combination of continents, oceans, and atmosphere makes it unique among all the planets in the solar system, and perhaps in the galaxy. These features also create the conditions for life in all its diversity. But where did the land, water, and air come from? And how do these systems work together to produce the complex phenomena that are evident everywhere on this beautiful planet? Consider these cases: * The steady, slow decay of radioactive elements deep inside Earth provides the heat that keeps our planet at a slow boil, moving massive amounts of mantel rock in a cyclic pattern of convection and creating plate tectonics. * A mid-ocean ridge system snakes around Earth like the seam on a baseball. The slow drift of Earth's tectonic plates—moving at the rate that hair grows—splits the ridges apart, pulling rock up to fill the gap. * One of the most energetic environments on Earth is where land and ocean meet: the seashore. Waves crashing against the coasts of North America can be heard as background static on seismometers located at the center of the continent. An Astonishing Journey How the Earth Works takes you on an astonishing journey through time and space. In 48 half-hour lectures, you will look at what went into making our planet—from the big bang, to the formation of the solar system, to the subsequent evolution of Earth. You will 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 around like so much froth on the surface of a pot of soup. Earthquakes, volcanic eruptions, and tsunamis are byproducts of our planet's ceaseless activity, and you will focus on specific examples of each to learn why and when they occur. Volcanic activity has produced the atmosphere as a side effect, and you will learn how this sea of air functions at the global scale. Earth's surface is mostly water, and you will explore the cycling of this vital substance throughout the planet, along with its role in climate, erosion, plate tectonics, and biology. Not only are humans at the mercy of our planet's natural forces, but we ourselves have also become agents of change. We are altering the Earth's land, water, and air faster than any other geologic process. This will be another theme of your journey: how humans have transformed watersheds, leveled mountains, changed the balance of gases in the atmosphere, and caused the extinction of enough species to hasten the end of the 65-million-year-old Cenozoic era. It is vitally important that we understand the nature of our geologic powers, if we are to have any hope of controlling them. Your Guide: A Scientific Sherlock Holmes 作者近照：

Professor Michael E. Wysession is the ideal guide for this expedition. A geophysicist with a specialty in seismology, he has developed techniques for using seismic waves from earthquakes to deduce the three-dimensional structure of the interior of the Earth. Like a scientific Sherlock Holmes, Dr. Wysession uses this approach to “see” into a realm that was previously more mysterious than galaxies billions of light years away. As a leader in geoscience education, Professor Wysession has wide experience teaching Earth science to students from high school through the advanced graduate level. For this course, he assumes no prior background in science and introduces all the concepts you will need to understand how the Earth works—from basic physics, chemistry, astronomy, and biology to the fundamentals of geology, mineralogy, hydrology, and atmospheric science. Each lecture builds upon preceding ones to deepen your understanding of key concepts. For example, Professor Wysession spends the first four lectures laying the groundwork for the introduction of plate tectonics in Lecture 5. Almost everything he discusses thereafter relates in some way to this revolutionary theory, which is as instrumental to Earth science as the Copernican theory is to astronomy. How the Earth Works is the perfect complement to The Teaching Company's in-depth geology series, Nature of Earth: An Introduction to Geology. Taught by Professor John J. Renton, that course covers Earth's minerals, rocks, soils, and the processes that operate on them through time. How the Earth Works also touches on these subjects, but it ranges farther afield to investigate Earth as a system, as one might study a complicated machine. Such a focus makes this course truly a user's manual to the planet. Whether your interest is geology, cosmology, biology, climate science, or even human history, Professor Wysession shows how these perspectives fit into the comprehensive picture of our planet. Fitting the Pieces Together You don't have to travel far to realize that we live in a world of startling contrasts—in landforms, natural resources, flora and fauna, climates, vulnerability to natural disasters, and other characteristics. Professor Wysession shows that these different features are like interlocking puzzle pieces. Learning how the different pieces fit together gives you insight into some very interesting questions: * Why is there gold in California and coal in Indiana, and not the other way around? * What does the tilt of Earth's axis have to do with the evolution of deciduous trees? * Why are volcanic eruptions predictable, but earthquakes (so far) are not? * What is the link between the shape of Earth's orbit and the size of mammals? * How does the movement of Earth's tectonic plates affect climate change? * What does the mid-ocean ridge environment have to do with the origin of life? Get "Under the Hood" of Earth How the Earth Works includes many simple activities that make concepts clear. Whether through illustrating the viscosity of magma with day-old oatmeal or showing how a laptop computer can double as a seismometer, Dr. Wysession believes learning works best when you demonstrate and describe basic principles. You will marvel at the lessons he can impart—and that you can do yourself—with a chocolate bar, modeling clay, an orange, and even a piece of Afghan flatbread (which nicely reproduces the complex faulting seen along the mid-ocean ridge system). He also brings in intriguing rock samples with wondrous stories to tell about the history of our planet. In addition to giving you the pleasure of looking under the hood of Earth and understanding how it is put together and how it works, this course provides a new context for understanding contemporary events and issues such as natural disasters, climate change, resource scarcity, and renewable and nonrenewable energy sources. You may also be surprised to learn the central role that Earth's ceaseless activity has played in historical events, from the origin of civilizations to the fall of Rome and the voyages of Leif Eriksson. Finally, think back to that traveler from another galaxy. The space voyager's first impression of Earth would doubtless be of its sheer beauty: its intensely blue oceans, brilliant white polar caps, tan deserts, and deep greens of rainforest, overlain by graceful swirls of clouds. How did it all come about? What was it like in the past, and what will it be in the future? What is the role of life in this intricate system? Prepare to investigate the miracle and mystery of the amazing planet that nurtures us all. Available Exclusively on DVD Due to the visual nature of the subject matter, this course is available exclusively on DVD. It features many graphics to aid your learning, including animation, videos, and approximately 800 images. Professor Wysession performs several entertaining demonstrations to illustrate his discussion. About the Professor Michael E.
