Neil deGrasse Tyson once said that Albert Einstein once said that Marie Curie once said that Isaac Newton once said that science is really pretty neat. The beautiful thing about science is that every answer just brings more questions. Sure, you may know that the earth revolves around the sun, but do you know if T. rexes could play patty-cake? Do dogs realize when we’re naked? Would cats notice if robots replaced us? So, be a deep thinker and do some science in this chapter: put forth a hypothesis, test it, and then let your friends tear it apart. Most days, that’s just life. But today, it’s science!
