Astronomy Physics

Einstein's special theory of relativity made time travel to the future a possibility, and later his general theory of relativity showed us that loops in spacetime could exist, meaning that we might be able to bend time backwards, too. But what are the practicalities of making time travel possible? What do we still need to know? How do we deal with any paradoxical twists in time - and could quantum physics hold the answer?

Forty-four science articles using the Rational Scientific Method of Inquiry. These subjects are covered in the book Curious Chain of Events, and this is the first in a series of Rational Science books.

Neil deGrasse Tyson, a former star, amateur wrestler at Harvard who went on to become an award-winning astrophysicist, might be the most well-known science communicator in the United States since the late Carl Sagan. Tyson, who has served as the director of the Hayden Planetarium in New York City since 1996, had published a dozen books prior to Astrophysics for People in a Hurry; all of them have been aimed at a popular audience. In spite of that, Astrophysics for People in a Hurry is probably his most accessible and scaled-down work to date.

A collection of chapters from the previous five volumes in the Rational Science series. We discuss the difference between objects and concepts, hypothesis and theory, and science and technology. We learn about light, time, and mass, the Big Bang Theory, black holes, and Mach’s principle. We find out about dinosaurs and why they were so big. We look at a couple hypotheses on planetary and solar system formation. From atom to sun, we learn to think about reality in new ways.

A fascinating piece of historical scientific writing, written in 1913 by E. Walter Maunder (F.R.A.S.), the superintendent of the Solar Dept. at the Royal Observatory in Greenwich. The book is a snapshot in time showing the evolution of thinking on the solar system and cosmology. The author considers, in fine detail, the plausibility of life on other planets within our solar system, the requirements for such life, and the barriers that life faces.
