When I was a mechanical engineer, 70% of the information I needed was in that book. I used it literally every day. It's no more expensive than IntelliJ, and 1/10th or less of the price of the software packages we were using. It's an absolute must have for a professional. Not to mention you use it in about a half dozen college classes. Used copies are probably cheaper, and the information hasn't changed in any meangingful way in ages.
