The first book I read on an ereader was
Death by Black Hole: And Other Cosmic Quandaries by Neil deGrasse Tyson.
Spoiler:
...in which the famed
* astrophysicist tackles such pressing questions as why aliens will never hear our AM radio shows, what color the universe is (a light shade of beige), why the science in the movie "Independence Day" sucked ("the alien mothership must have been powered by the same release of Apple Computer's system software as the laptop computer that delivered the virus"), what the chances are that your tombstone will read "killed by asteroid" (about the same for "killed in an airplane crash"), and others. There are useful tidbits of knowledge, such as the fact that electromagnetic forces are so much stronger than gravity that "a child's magnet easily lifts a paper clip off a tabletop in spite of Earth's formidable gravitational tug", what are the chances that Earth will be hit by the asteroid Apophis in 2036 (stay tuned—it all depends on the exact trajectory it takes when it passes between between the Earth and our moon on (gulp!) Friday the 13th, April, 2029!), why intelligent design should not be allowed in science textbooks, and why "it's always best to avoid things that decompose the molecules of your flesh" (such as UV rays).
BIG NEWS! EXTRA! EXTRA! READ ALL ABOUT IT!
It was announced earlier this month that
Tyson will be hosting a new television sequel to Carl Sagan's Cosmos in 2013!
