Yep, you have to be very careful when printing with aluminium powder. An unfortunate example: "Two Workers Killed and Two Injured in Explosion at 3D Printer Plant"…
Reminiscences of a Stock Operator is from 1923 and is considered an investing classic. It is a good read (and still relevant) if you are remotely interested in trading.
I found the Stumbling Robot list of math books to be a bit better. It lists multiple books for a number of topics and explains the differences / difficulty. http://www.stumblingrobot.com/best-math-books/
