Although he doesn't know anything about the subject (at first), he is eager to learn, and takes information that he gets from the world's leading experts and explains it to us in a way that makes it exciting and relevant.

Curiosity stirs the soul of every human. Who has not wondered about how the human body works? Can we drown from drinking too much water? What is a black hole? Can black holes allow us to time travel? Is spontaneous human combustion possible? Do identical twins have the same fingerprints? How do scientists age dinosaur bones? How does gravity make things fall? Why do sunflowers always face the sun? What about a man flying with wings? How big would those wings have to be? How tall can a human grow? Why are tennis balls fuzzy?

Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day - and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History", the most exciting new approach to understanding where we have been, where we are, and where we are going.

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

Richard Dawkins, the world’s most famous evolutionary biologist, presents a gorgeously lucid, science book examining some of the nature’s most fundamental questions both from a mythical and scientific perspective. Science is our most precise and powerful tool for making sense of the world. Before we developed the scientific method, we created rich mythologies to explain the unknown. The pressing questions that primitive men and women asked are the same ones we ask as children. Who was the first person? What is the sun? Why is there night and day?

In Firmament, atmospheric scientist and science communicator Simon Clark offers a rare and accessible tour of the ins and outs of the atmosphere and how we know what we know about it. From the workings of its different layers to why carbon dioxide is special, from pioneers like Pascal to the unsung heroes working in the field to help us understand climate change, Firmament introduces us to an oft-overlooked area of science and not only lays the ground work for us to better understand the debates surrounding the climate today.

I don’t think many people know that the moon is not actually a perfect sphere; it is in fact shaped slightly like a lemon with bulges on both sides. Or that a day on Mercury lasts longer than a year.
