Unlike the rest of life on the planet (as far as we know), humans have evolved with an insatiable desire to make sense of the world around us. Our senses are not equipped to see the universe as it is, and routinely let us down in that quest— the world appears flat, the stars seem fixed in the heavens. That is why we invented math and science— the ultimate toolkit to explain how the world really works.In this book, mathematician Hannah Fry and geneticist Adam Rutherford investigate everyday mysteries (does your dog love you?) alongside the burning questions of time, space, and the origin of the universe. What will the end of the world look like, and when will it happen? What is time, and where does it come from? Approaching these questions and more with science and math rigorous and playful, Rutherford and Fry celebrate the weirdness of the cosmos, and reveal its secrets along the way.
