Bests & Worsts Reviews from Amazon

We're living in this crazy world where some people don't believe in vaccinations, climate change, or evolution... for those that do, these books are a great basis to get your kids started early. Sure, there are some slight cognitive leaps ("now the ball is quantized!"), but generally, I have very few complaints about these books. They totally beat a lot of the mindless garbage, or worse, anti-science propaganda that's out there.
