I’ve just added the new Mathematics Category which covers basic arithmetic, algebra, some geometry and of course calculus.
While obviously the science of math has progressed quite a bit since the 1800s and early 1900s I suspect that few, if any of you, unless you were a math major in college have a set of math textbooks sitting on your shelves. While ideally it would be nice to have such a set it’s not something most of us think of in the realm of “survival Books”. we’re more likely to be thinking food, shelter, security, etc.
When you look through the other categories in the Library such as Engineering, Sailing, Navigation, steam Engines and so on it quickly becomes apparent that many of them depend on a solid grounding in Math. Hard to perform calculations to navigate a ship if you don’t understand geometry and trigonometry.
hard to do much on the field of chemistry or electronics without an understanding of the calculus.
So this provides a range of introductory material from some of the basics aritmetic. An introduction in algebra. Some trigonometry and geometry and finally a fair amount of calculus.
While you may never need them it’s nice to have them on hand.
If you find yourself in a situation where you have to teach children basics such as reading, writing and arithmetic these cover the basics and a good bit beyond.
Another way to think of it is this… if you canteach your children what’s in these books or even a fair percentage of it they will be far beyond the overwhelming majority of both children and adults in our existing “technological” world.
