Before Einstein, how the universe began was a question for theologians, not scientists. Over a century later, we know much more, but not enough to do more than guess at what happened at the moment of the Big Bang and immediately after. Astrophysicist Dan Hooper, author of At the Edge of Time—a book that explores dark energy, dark matter and other things we don't yet understand—talks us through books about the Big Bang, and questions whether our entire understanding of the universe is about to be turned upside down.

Our experience of time is only weakly related to the fundamental realities of physics, says the physicist and best-selling author Carlo Rovelli. Here he selects five works for understanding the nature of time in its truer sense.

The World According to Physics, theoretical physicist Jim Al-Khalili's latest book, is his "ode to physics". Here, he talks us through the books that inspired his passion for physics, in an updated interview with Five Books.

Quantum physics is deeply confusing and its relation to reality the cause of heated debate among physicists since its discovery. Here, science writer Jim Baggott—who has spent more than three decades thinking about quantum mechanics and written a number of books about it—recommends books for better understanding what it’s about, and explains why how physicists approach it is so crucial to science’s credibility.

What are the best books for getting a teenager into physics? Kate Lee, a physics teacher at St Paul's Girls School, recommends books about NASA, space travel, and the Big Bang—and puzzles over the question of why it is so hard for young women to stay in physics as a profession.

Andrew Robinson, author of a biography of Albert Einstein, picks and talks through the five best Albert Einstein books and discusses the life and times of the 'unique genius.'

In science, the word 'nuclear' refers to anything to do with the atomic nucleus, whether you're using it to generate power or create weapons of mass destruction. Here, physicist and science educator Richard Wolfson recommends five books relating to things nuclear, from a book of graphic nonfiction about the Curie family to how fusion can save the planet.

What is string theory, and why should we bother finding out? Princeton physics professor Steven Gubser, author of The Little Book of String Theory, explains.

Contemporary physics is so complex that no single physicist can be said to have a decent grasp of the full picture. This makes communicating physics a formidable challenge.  Acclaimed popular science writer, Jim Baggott, talks us through this challenge by discussing his favourite physics books.

From Kepler's astronomy to Richard Feynman's quantum electrodynamics, Marcus Chown launches us into the world of cosmology.

David Goldberg, professor of physics at Drexel University, recommends the best books to start learning about cosmology. He explains his choices to high school student, Eric Bolton.

Public understanding of radiation needs to improve if people are to properly assess its benefits and risks argues author and academic, Timothy Jorgensen. From the discovery of radio to a cancer cluster in New Jersey, he chooses highly readable books illuminating different aspects of radiation.

Blaming "the quants" for the 2008 financial crisis is simplistic and short-sighted, says the author of The Physics of Wall Street. He picks five books showing the contribution physics has made to understanding financial markets.

Philip Plait urges us to remember that “science isn’t an encyclopedia of facts to memorise. It's alive." The astronomer and author of the acclaimed Bad Astronomy blog discusses books that can't help but light the fire of interest in all things astronomical. He looks at how we can date the age of the universe, the danger of solar flares, and why Pluto is no longer classed as a planet.

The astronomy professor says the process of scientific discovery can be slow and messy – but that reading about some of the extraordinary personalities involved brings the history alive

Award-winning British physicist, Athene Donald, tells us how to fight preconceived ideas about gender and suggests reading that could inspire women to pursue careers in science.

Best-selling science writer, Dava Sobel, recommends books about the men whose painstaking work changed our understanding of Earth’s place in the universe.

We’re in a “dual energy crisis”, says the author of Clean Energy Nation, and not doing enough about it. He tells us what we must do if we’re to overcome our dependence on oil and limit the damaging effects of climate change

The chief executive of Good Energy says we need to think big if we want to cut our use of high-carbon energy. She tells us about the intersection between business, politics and doing the right thing

The Professor of Astro-Physics at Oxford University selects five seminal books on the workings of the universe. Explains that to appreciate the true beauty of science is to understand its simplicity and universality

The Science Correspondent for the Uk's Channel 4 discusses the magical allure of science. He chooses five great books on subjects ranging from genetics to natural history and astro-physics
