Why The Universe Is Probably Flat
A very interesting presentation describing why the Universe is thought to be flat. Another reason not mentioned is that in a flat Universe the total energy would be zero as gravity can have negative...
The Inside Story Of The Moon Landings by Alan Shepard
Our Recommended Book Of The Moment
When and how did the universe begin? Why are we here? What is the nature of reality? Is the apparent “grand design” of our universe evidence of a benevolent creator who set things in motion—or does science offer another explanation? In this startling and lavishly illustrated book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about these and other abiding mysteries of the universe, in nontechnical language marked by brilliance and simplicity.

It’s Only Rocket Science
Most amateur astronomers – and many of those with similar interests but who are not currently practising observers – have only a sketchy understanding of space flight. This book provides an introductioauty of this book, written by an engineer who is also an accomplished science writer, is that it covers the subject comprehensively, and yet is almost entirely descriptive and non-mathematical. It deals with all aspects of space flight, from how to leave the Earth (including the design of the rocket, mission planning, navigation and communication), to life in space and the effects of weightlessness. The book also includes sections describing how an amateur can track satellites and understand their orbital parameters. mmunication), to life in space and the effects of weightlessness.

A Brief History Of Time
#1 NEW YORK TIMES BESTSELLER
A landmark volume in science writing by one of the great minds of our time, Stephen Hawking’s book explores such profound questions as: How did the universe begin—and what made its start possible? Does time always flow forward? Is the universe unending—or are there boundaries? Are there other dimensions in space? What will happen when it all ends?
Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and “arrows of time.”
