The heart of this course examines the planets themselves, and reveals how they are constructed and how they differ from one another. By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.
"Wow... just wow"
As far as we can see there are countless other galaxies of all shapes and sizes set within an ever-expanding space that was created in a "Big Bang" nearly 14 billion years ago. Along with solutions to old puzzles, however, come new riddles, as most of our Universe appears to be in the form of some kind of unseen "dark matter" and incomprehensible "dark energy" whose natures and origins remain unfathomable.
This course guides listeners through the sights of the naked- eye sky, wherein we directly witness the effects of the turning and revolving of the Earth, the artistry painted by the human mind using the sky and stars, and how the view changes with time and with our place on the planet.
"Not as Good as Professors Kaler's Other Lectures"

But was this great adventure everything he dreamed it would be? Toby Tyler or, Ten Weeks with a Circus is a classic story beloved by generation after generation of children. Author James Otis Kaler actually traveled with the Phineas T. Barnum Circus as a young reporter, and he used his firsthand knowledge to acquaint children with the behind-the-scenes details of what the circus is really like, while introducing the unforgettable character of Toby Tyler.
