in order to use the chinese remainder theorem, the moduli of the congruences must be coprime. is there either 1. a way to solve multiple congruences which share a factor other than crt, or 2. a way to convert the congruences which conflict into ones which do not? submitted by /u/jacoberu [visit reddit] [comments ..read more

Hi everyone! I'm planning to apply for master's programs in pure mathematics with a bachelor's degree focused on applied mathematics, statistics, and physics (Bsc stats with phy and math as minors). Is it possible to transition from an applied mathematics background to pure mathematics at universities? If not, would it be advisable to first apply for applied mathematics master's programs and then shift towards pure mathematics later? Any advice or insights would be appreciated. Thank you! (P.s. I have completed essential algebra, calculus and other similar courses in my coursework and I am al ..read more

Hi everyone, I'm a second-year university student, and so far, I've taken an abstract algebra course and went through most of Hungerford / Dummit & Foote / Atiyah & MacDonald. I enjoy the difficulty and elegance of algebra, but I am also interested in theoretical cryptography for the content of the theorems. Even simple theorems about the infeasibility of perfect secrecy are very interesting to me. Here's the problem: as far as I can see, although theoretical cryptography employs and blends many different fields, it uses most of these on a surface level. The algebra used in cryptograp ..read more

Just recently I asked ChatGpt to solve some physics question, I just wanted to check my answer. Everything started very well. He understood the problem correctly, used all the necessary formulas and eventually combined the final expression that was the same as what I got. All he had to do was simply substitute the values into this expression and give the answer. But the answer was completely different and not even close to mine. I spent quite a lot of time trying to find my mistake until I finally decided to regenerate his response once again. He gave a slightly different approach and… a comp ..read more

Dear Logicians, I'm Sharing "NSO and GSSOTC: A Two-Pager for the Logician," authored by Ohad Asor. The work dives into two sophisticated logical frameworks: Nullary Second-Order Logic (NSO) and Guarded Successor Second-Order Time Compatibility (GSSOTC). These frameworks aim to address classic limitations in logic, like Tarski's "Undefinability of Truth," and extend the capabilities of logic systems in handling self-referential and temporal statements. Here's a brief outline of the key ideas: 1. NSO: This framework abstracts sentences into Boolean algebra elements, avoiding direct syntax acces ..read more

I know this is commonly talked by people studying math. But I want to know your idea. The first until fourth postulate was defined as something under euclidean geometry. Why combine the fifth postulate together with this 4 if the last postulate is applicable on hyperbolic and spherical geometry? submitted by /u/Short_Finding2070 [visit reddit] [comments ..read more

Hi. I've got an interview coming up with Brighterly, and I'm curious to hear from anyone who has already gone through the application process or worked with them. What was your experience like?
