What is the very smallest thing you can think of? A grain of sand? What about an atom? Every object and every living thing--from the biggest star to a speck of dust--is made of atoms. But even atoms are made up of smaller particles, and inside those smaller particles, you'll find quarks! Quarks are the smallest thing there is, but they make a big impact on our universe. From the Big Bang, supernovas, and black holes to the chips inside your computer, quarks have seen it all. In this fun, accessible book teeming with fascinating facts and full-color illustrations, Christopher Edge and Paul Daviz lead a journey beyond the science classroom and into the quantum universe to explore what quarks are all about.
