> When I began to teach 3D vectors two years ago, I realized I first had to teach it to myself, because I’d never actually learned it. My college courses skipped straight to “n-dimensional vectors.”
This sums up why I disliked higher level math classes in college so much. We never actually did anything _useful_ with the math, we never actually applied it to real life, we always just rapidly advanced to the general case ("n-dimensions"), took a test, then moved onto the next topic.
- dash2 5y agoThat's just why some people like it. My favourite review on Amazon, of Rudin's Principles of Mathematical Analysis (https://www.amazon.com/gp/customer-reviews/R23MC2PCAJYHCB/ref=cm_cr_getr_d_rvw_ttl?ie=UTF8&ASIN=0070856133 https://www.amazon.com/gp/customer-reviews/R23MC2PCAJYHCB/re...): > It is not possible to overstate how good this book is. I tried to give it uncountably many stars but they only have five. Five is an insult. I'm sorry Dr. Rudin.... > "The material is not motivated." Not motivated? Judas just stick a dagger in my heart. This material needs no motivation. Just do it. Faith will come. He's teaching you analysis. Not selling you a used car. By the time you are ready to read this book you should not need motivation from the author as to why you need to know analysis. You should just feel a burning in you chest that can only be quenched by arguments involving an arbitrary sequence {x_n} that converges to x in X. >... if you'r a student and find the book too hard? Try harder. That's the point. If you did not crave intellectual work why are you sitting in an analysis course? Dig in. It will make you a better person. Trust me. > Or you could just change your major back to engineering. It's more money and the books always have lots of nice pictures.
