Physics of the Impossible by Michio Kaku.
The cover of this book caught my eye today. Look at the little TARDIS, flying in and out of that wormhole!
I love books that try to explain the science behind sci-fi, and this one explores whether or not it will ever be possible to have phasers, force fields, teleportation and time travel. I flipped through it for a while, and it looks like a really interesting read. But the cover is kind of misleading. Nowhere in index is there any mention of Doctor Who or the TARDIS! There is a whole section on time travel, citing Back to the Future, Star Trek, The Time Machine by HG Wells, and A Connecticut Yankee in King Arthur's Court by Mark Twain, but not word one about a police box that's bigger on the inside.
I feel a little cheated! I wanted to see how Kaku would address the TARDIS and the way Doctor Who handles time travel. Why would they put the TARDIS on the cover of a book that doesn't mention it?*
*I know: to sell books to geeks like me, but come on, not even one mention?
