Games for people who like to play around with black holes

The great difficulty of relativity theory is that it is so foreign to our day-to-day experience that it is difficult to get an intuitive feeling for its applications. This is especially true when dealing with the extreme conditions existing in a black hole.

Pickover has done an admirable job by describing a journey into a black hole and proving simple programs and equations that enable us to play with these strange and wonderful objects.

"Black Holes - A Traveler's Guide" can be considered a work book for Kip Thorne's "Black Holes & Time Warps". It provides some simple BASIC programs that require no more background than high school algebra to calculate quantities such as the circumference of a black hole and its mass.

Other programs are listed to create interesting "pictures" of black holes. There are 11 full color plates that are based on these and other programs, but take advantage of some very powerful graphic software and hardware.

Since travelling into a black hole itself is not recommended (look up tidal forces in the index if you don't know why), reading "Black Hole - A Traveler's Guide" is possibly the next best thing.
