In his introduction to a revolutionary theory of the cosmos, Martin Bojowald shows how the big bang theory may give way to the big bounce theory, which describes our universe as an eternal series of expansions and contractions, with no beginning and no end. In 2000, Bojowald, then a twenty-seven-year-old postdoctoral student at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology, or LQC, was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.

Did you know that for every pound of people on earth, there are 300 pounds of insects? Or that millions of years ago some of these bugs actually weighed that much? Well, during prehistoric times, before dinosaurs ruled the earth, bugs did; and just like today the seas, skies, and lands were covered by these creepy-crawlers. There were dragonflies with wings that reached a yard across in length, and millipedes that grew to over six feet long! But what is even more fascinating is the fact that all of these creatures in some form or another learned to adapt and survive to become the insects and sea beasts of today. In this fully illustrated picture book, readers will be captivated by the detailed information of prehistoric insects, arachnids, and their relatives. Chock-full of facts about fossil formation, insect evolution, flight theories, and geologic time, Bugs Before Time will mesmerize entomologists of all ages. Author Cathy Camper's absorbing text, and artist Steve Kirk's extraordinary paintings combine to re-create a world where giants reigned.
