Need Einstein’s theory explained? How about an evaluation of Sir Isaac Newton’s contributions to physics?

Sean Carroll’s your man. His new book, “The Biggest Ideas in the Universe,” offers up equations, history and some basic math principles but seeks to do it in an easy-to-understand manner.

But then you may already know about Carroll. He’s written a number of books such as “From Eternity to Here” and “The Particle at the End of the Universe” as well as accumulating over 4 million views on his YouTube series where he routinely explains mind-boggling concepts.

Carroll decided on a career in physics at the tender age of 10, reading books at his local library on black holes and the Big Bang Theory. “I thought that was the most interesting stuff in the universe,” he told Steve Tarter.

Now a professor at Johns Hopkins University, Carroll has some counsel for those of us who have stressed about the concept of eternity or the miracle of life. “I understand it can be disturbing to contemplate some of these ideas but nature doesn’t care,” he said.

As a frequent consultant to Hollywood, Carroll said he understands the primary purpose of a film is entertainment “but when things obey the laws of physics, the reality can get people more immersed in the movie,” he said.
