It just seems odd that Linear Algebra stresses them exclusively when other non-linear transformations can still be extremely helpful. In stuff like machine learning non linear kernels help us see non linear patterns such as circular, logarithmic, exponential, quadratic, etc. Is there an analogous math to linear algebra that focuses on non linear transformations?
Help! I’m studying for a quiz and I saw this question in my book.
A patient has an infection that, if it exceeds a certain level , will cause the patient’s death. He is given a drug that will inhibit the spread of the infection. The drug acts in such a way that the level only increases by 65% of the previous day’s level. On the first day, the level of infection is measured at 450. The critical level of infection is 1,280. Will the infection reach its critical level?
Hello, I have just been reading about illegal prime numbers and I am not 100% sure I am understanding this correctly,
apparently https://en.wikipedia.org/wiki/Illegal_prime states that ” Its binary representation corresponds to a compressed version of the C source code of a computer program implementing the DeCSS decryption algorithm, which can be used by a computer to circumvent a DVD’s copy protection”
and this is by pure chance? it just happens to represent the binary of this source code in total? Not just one small part of it?
This seems like the chances of this is insanely tiny, how would I work out the probability of this happening? To me it seems almost impossible.

edit: http://primes.utm.edu/glossary/page.php?sort=Illegal it seems the code existed, then someone worked out that it could be translated into a prime number through some various means. But it still seems very crazy that this can work at all.
I thought it’d be fun for people to post their favorite mathematicians, and give some type of story or anecdote about how they became your favorite/why they are your favorite. For me, I’ve always been a fan of Fermat, just because I’m convinced that there is a simple, eloquent proof to his last theorem, as he suggested in one of his notebooks, and that somewhere out there still exists a notebook where he actually wrote the proof out.
