It's Joever For Your Math Book Investment

The ultimate mathematical tragedy: buying a book about "The Largest Known Prime Number" only to have it immediately rendered obsolete by a new discovery. This poor soul just purchased what's essentially a mathematical history book now! The new Mersenne prime (2 13627984 -1) took six years to discover using specialized GIMPS software and GPUs, making this book buyer's timing spectacularly unfortunate. Nothing says "money well spent" like owning documentation of the second-largest known prime number.

How To Spot An Outdated Textbook

Nothing dates a chemistry textbook faster than an incomplete periodic table. This one's showing just hydrogen, helium, lithium, and beryllium—making it about as current as a stone tablet with "fire = hot" scribbled on it. The modern periodic table has 118 elements, but apparently this book went to press when the universe was still in beta testing. The joke about being published "half an hour after the Big Bang" is particularly brilliant because the first elements actually did form within minutes after the universe began. So technically, this textbook is only missing... *checks notes*... 114 elements and about 13.8 billion years of scientific progress. No big deal.
