I started reading this science book by Neil deGrasse Tyson. It's small but I'm learning plenty. I didn't get everything on The Big Bang. My favorite parts were about these guys in the '40s who took in all this information they had back in the day and try to figure out what the temperature of The Universe is and end up only being 2 degrees off. Amazing. And I read how these guys working for AT&T found Cosmic Microwave Background.
