Britain's most famous mathematician takes us to the edge of knowledge to show us what we cannot know. Is the universe infinite? Do we know what happened before the Big Bang? Where is human consciousness located in the brain? And are there more undiscovered particles out there, beyond the Higgs boson? In the modern world, science is king: weekly headlines proclaim the latest scientific breakthroughs and numerous mathematical problems, once indecipherable, have now been solved. But are there limits to what we can discover about our physical universe? In this very personal journey to the edges of knowledge, Marcus du Sautoy investigates how leading experts in fields from quantum physics and cosmology, to sensory perception and neuroscience, have articulated the current lie of the land. In doing so, he travels to the very boundaries of understanding, questioning contradictory stories and consulting cutting edge data. Is it possible that we will one day know everything? Or are there fields of research that will always lie beyond the bounds of human comprehension? And if so, how do we cope with living in a universe where there are things that will forever transcend our understanding? In What We Cannot Know, Marcus du Sautoy leads us on a thought-provoking expedition to the furthest reaches of modern science. Prepare to be taken to the edge of knowledge to find out if there's anything we truly cannot know.

Lifelong best friends and next-door neighbors Hannah and Emory have never gone a single day without talking. But now its senior year and they haven't spoken in three months. Not since the fight, where they each said things they couldn't take back. They're aching to break the silence, but those thirty-six steps between their bedroom windows feel more like thirty-six miles. Then one fateful night, Emory's boyfriend, Luke, almost dies. And Hannah is the one who finds him and saves his life. As Luke tries to make sense of his near-death experience, he secretly turns to Hannah, who becomes his biggest confidante. In Luke, Hannah finds someone she can finally talk to about all the questions she's grappling with. Emory just wants everything to go back to normal -- the way it was before the accident. She has no idea why her relationship is spiraling out of control.
