The title says it all. Just a bunch of crazy ideas. From space elevator, to the new ways of playing chess, to making sure, that the apartment does not smell of cat's shit or experiment in trying low-calorie diet.
He tries to give evidence of the possibility for each idea. Not every time did he convince me, but I do not think that the point of the book was in specific idea.
Not, what I took from the book was the new wind in coming up with the crazy ideas. The whole presentation of the ideas in various field make me feel, like maybe I can come up with something smart as well.
It is a good book, and a light reading. The ideas are short, and they are not connected, so the reader can just read the ones, he or she is interested in. good for the summer light reading.
