5 Insane Ways Words Can Control Your Mind On some level we already know that language shapes the way we think. We're automatically more afraid to fight a guy named Jack Savage than somebody named Peewee Nipplepuss, even if we've never seen either of them before. It's totally illogical, but you probably run into an example of that every day, and don't notice it.

7 Man-Made Substances that Laugh in the Face of Physics The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive.
