why doesn't baby poop smell bad?
[ "Their GI tract is still colonizing. This is part of why they need certain nutrients more than others, because we get some of it from bacterial metabolism in the gut.

Relativity (also difference between general and special) as well as string theory
[ "Special relativity: The speed of light is the same in all reference frames. You can't accelerate to the speed of light.

Why do some memories get stronger with repeated thinking and some weaker?
[ "Typically, accessing a memory will strengthen it. But there's a catch. \n \nResearch has shown that accessing a memory causes it to be re-written back into our long-term memory.
