Springer made a bunch of books available for free, these were the direct links

Let's solve the following physics problem using Symbolism, a computer algebra library for C#.

One strategy in a snowball fight is to throw a first snowball at a high angle over level ground. While your opponent is watching the first one, you throw a second one at a low angle and timed to arrive at your opponent before or at the same time as the first one.

Assume both snowballs are thrown with a speed of 25.0 m/s.

The first one is thrown at an angle of 70.0° with respect to the horizontal.

Moved

Now located at https://github.com/JeffPaine/beautiful_idiomatic_python.

Why it was moved

Github gists don't support Pull Requests or any notifications, which made it impossible for me to maintain this (surprisingly popular) gist with fixes, respond to comments and so on. In the interest of maintaining the quality of this resource for others, I've moved it to a proper repo. Cheers!
