please don’t block me but since getting into control theory i’ve grown quite fond of the dot notation. we all live with respect to time here. a little dot never hurt anyone

oh god I'd never block someone over this, it's really a joke opinion above all. hi friend :D

unfortunately I don't think it really makes sense to default to time - really, I don't think any differential operator should "hide" the variable of derivation, including Lagrange notation, but I understand the need for a short-form derivative. However, so many physical functions and relations depend on a change in length, which doesn't always scale nicely to time in my opinion, so can make for some ugly higher-order derivatives.

I will say: haven't learned control theory yet, not sure that I'll cross that path in my degree :( so I don't know how useful it probably is and how amazing a shorthand it is for you lol. do what you like! I just don't like the dot because of the aforementioned reasons, and also because it's really easy to accidentally make an errant dot vs. an apostrophe or d/dx. much love <3<3

a fellow pure math + mathphys person! What are you up to these days?

hello friend oh my goodness!! what a cool and amazing choice of major :)

right now I'm finishing up some more applied math requirements, since I started things off leaning into pure math courses. I'm also trying to compile a good "research pitch" for some research ideas (namely, general solutions for 2nd order ODEs).

how about yourself? any fun courses or side projects?

I've never heard nabla be called del, but my old calc teacher always called the partial del

so is del nabla or is del partial

the internet is being completely inconsistent

my theoretical physics teacher calls nabla del but i've always said nabla

and i swear i've heard someone call partial del??

augh

shoutout to method of undetermined coefficients

"how do I solve this differential equation?"

"uh just guess"

Hot take but my imaginary part is 0.

my main goal in life is to be wrong about quantum physics in ways that make me sound smarter than the other people inevitably wrong people around me

Cauchy sequence? Fort topology? Some weird dream you had, mine was about chasing rabbits in a field. Now get off your bed, our human just woke up and sources say she’ll mix some wet food in with our kibble today

that's not very modern of him

my Relativity and Modern Physics spent 5 minutes complaining about singular "they" in class

because, when he did the class 20 years ago, when making up characters in problems and thought experiments he would make up gender pronouns for them. but now it's all just "they"

i need to email him about neopronouns

A friend at school has a textbook where on one of the pages there are some very intense circling around particular formulas and a couple dried out teardrops at the bottom of the page.

The best part? This page has some of the most important formulas we need for this topic

Tldr, we've started referring to these formulas as "the trauma equations"

After much reflection, I think I have a good plan for shifting my research into the direction of pure mathematics again.
