About the Lecturer
Mark Whittle
University of Virginia
Ph.D., University of Cambridge
Dr. Mark Whittle is Professor of Astronomy at the University of Virginia, where he has been teaching since 1986. He teaches on the solar system, stars, galaxies, cosmology, and observing techniques. He also gives frequent public lectures, and he is committed to community outreach on all areas of astronomy, particularly cosmology.
Professor Whittle's research centers on various aspects of nuclear activity in galaxies, a phenomenon that arises from gas falling onto supermassive black holes. His most recent work focuses on the properties of jets that emerge from Seyfert galaxies and the role they play in energizing the central few thousand light-years. Professor Whittle uses both optical and radio telescopes for his research, including the Hubble Space Telescope.
Professor Whittle was a Mackinnon Scholar at Magdalen College, University of Oxford, where he obtained his B.A. Honors in Physics, First Class. He earned his M.A. in Physics at Oxford and his Ph.D. in Astronomy at the University of Cambridge.

36. A Comprehensible Universe?

Evidence for the birth of the universe is raining down on you. It's called the cosmic microwave background, and it's had quite a journey. Born in the stupendous annihilation of matter and antimatter seconds after the big bang, trapped in the hot plasma of the expanding universe for 380,000 years, and then suddenly released when the universe cooled to the point that atoms could form, this echo of creation has been on an uninterrupted voyage through space for 13.7 billion years-until it reached you. The cosmic microwave background is just one of the many clues about the history and nature of our universe that make the science of cosmology a wondrous, fascinating, and philosophically profound field of study.
Cosmology: The History and Nature of Our Universe introduces you to the biggest story of all in 36 half-hour lectures that cover the origin, evolution, composition, and probable fate of our universe. This detailed and accessible course, presented by award-winning Professor Mark Whittle of the University of Virginia, incorporates more than 1,700 stunning illustrations.

Описание:
The Perfect Time to Learn CosmologyAn expert on the dynamics of supermassive black holes at the cores of galaxies, Professor Whittle is an astronomer with a gift for making his subject vivid, understandable, and awe inspiring. For example, in explaining the vastness of the universe, he asks you to imagine yourself as a stupendous giant making billion-light-year strides through the cosmos, hour after hour. Even at this ultra-warp-drive pace, you would always find yourself in the middle of a uniform mist of galaxies with no end in sight.
Professor Whittle notes that we are the first generation ever to know in detail just how the universe came to be. Right now is the perfect time to learn cosmology, since researchers have just completed the work on more than a decade of breathtaking discoveries. The picture they have assembled is truly stunning in its richness and coherence and includes such findings as these:
* The universe began 13.7 billion years ago in a hot big bang.
* The geometry of the universe's space is 'flat,' supporting the theory of a cosmic origin in a rapid, inflationary burst of unimaginable speed.
* Ripples frozen in space at the instant of inflation formed the seeds from which galaxies and all later structure grew.
* The universe will expand forever at an accelerating rate.
Take an Intimate Look at the UniverseEinstein famously said, 'The most incomprehensible thing about the universe is that it is comprehensible.' As Cosmology shows, the universe is comprehensible at a remarkably deep level in simple, intuitive terms. As the course unfolds, you are introduced to the major clues that have gone into deciphering the mystery of the cosmos. Some of these clues involve concepts at the cutting edge of astrophysics, such as dark matter, dark energy, and cosmic inflation. Professor Whittle introduces these and many other ideas with inventive analogies and then builds on his explanations.
For instance, one of the most extraordinary aspects of the cosmic microwave background is that it tells us the universe was ringing with sound during its first 380,000 years. It took a satellite measuring minute fluctuations in the microwave background to disclose this property of the early universe. But the story does not end there because scientists can say a great deal about this primordial sound and what it means:
* Was it loud? Variations in the microwave background indicate that the sound was the approximate decibel level of front-row seats at a rock concert. (Professor Whittle picks Pink Floyd as a suitably deafening example.)
* What's the pitch? The primordial sound was 50 octaves lower than the range of human hearing. Just as larger organ pipes make deeper notes, so the universe's 'pipes' are cosmic in size and make extremely low notes.
* Was it musical? As you hear in Professor Whittle's different re-creations of the primordial sound, it had a harmonic complexity with a quality somewhere between a musical note and noise.
* What does it tell us? The primordial sound included pressure waves destined to grow into the largest structures in the universe.
At Home in the CosmosThere is also much to see in Cosmology. In addition to showing magnificent telescopic images, Professor Whittle illustrates his lectures with hundreds of informative diagrams, together with computer animations from NASA and other sources that give a three-dimensional perspective on the universe. You take a tour of our local supercluster, watch galaxies collide, and see 'rivers' of galaxies flowing toward pockets of invisible dark matter, among other compelling simulations. Such a comprehensive, in-depth presentation is only available with this course and not in any classroom, book, or documentary.
Professor Whittle enriches his lectures with a number of simple equations, such as Hubble's Law. But you don't need to follow
