I didn't know who discovered electrons and I didn't know the name of Dr. Hawking's book. And i will dispute your answer on #17. The Volume is the measure of the space an object occupies and the volume of an object of a specific mass will be determined by its density. Or if the density is fixed, the volume will be determined by the mass of an object. But other than that, Nice Quiz and a Thumbs UP!
