This ebook is a word problem with a story-like narrative. It covers multiple subjects besides math, such as social studies, science, and reading. The Island of Relativity is a metaphorical illustration of Einstein’s theory, addressing the question of why it’s impossible to travel faster than the speed of light. It is in two parts, each one taking place on this island. Part of the island represents space, and part of it represents time. In the first part, Einstein, himself, makes an appearance. The second part is based on The Tortoise and the Hare. Light races a neutrino, which was briefly thought to be faster than light. Throughout, there are questions involving math, analytical reading, and grammar.
