TTC - My Favorite Universe by Neil deGrasse Tyson 12 lectures of 30 minutes - 175 mb - mp3
Clear Science Teaching to Set the Stage for an Awe-Inspiring Course. Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter.
Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy.
The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe—including its eventual demise—are revealed in stark and often violent beauty. You learn:
how Saturn's rings were formed, and why they will eventually be lost
why low-density conditions are necessary to produce the drama of the northern and southern auroras
why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere
how black holes are formed and the extraordinary way in which they can wreak havoc in the universe
how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized
why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers
how astronomers actually look for new planets,
why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not.
