what do you think about 2023?
For my person, it was kind of bad, still better than the covid-years but not really good.
What do you expact for 2024? What are you plans?
New Year 2024
Hello all,what do you think about 2023?
For my person, it was kind of bad, still better than the covid-years but not really good.
What do you expact for 2024? What are you plans?

Tea
I love tea. I drink it without milk or sugar, because I'm interested in the flavor. I have a lot of tea leaves lying around, and it's fun to blend new variants. For example, there are breakfast and evening tea blends. The teas used in the breakfast blends tend to come from the India region, as they are stronger, however there is a unique flavor to tea from every region. Recently, I've blended Russian Caravan tea, which is based on the tea that traveled to Russia through the Mongolian steppes. As the tea traveled, it spent countless nights next to traders' campfires, imparting a smoky flavor that is still appreciated today.

It's useful to me, because I forgot basically all the mathematical notations I learned in highschool, but is there any effect to posting with that answer? Are posts with it downgraded in some way? It just seems like a very weird and possibly insecure system, especially since the captcha text next to "I don't know" isn't obscured in any way; it's easy enough for an OCR to read.
About the Captcha
I understand and like the idea of a math captcha, but I don't understand why there's an "I don't know" option.It's useful to me, because I forgot basically all the mathematical notations I learned in highschool, but is there any effect to posting with that answer?

Recommend me a programming language with meta-programming capabilities, strong types and functional features like map, filter, etc. that isn't too verbose and has good execution times.
And a project idea to test the language.

For those of you who don't recognize him, his name is Albert Einstein, famous for trying to apply differential geometry on physics or something.

The prerequisites for this reading course are point-set topology, linear algebra, undergraduate real analysis, and abstract algebra (standard undergraduate maths education). The textbook is self-contained with respect to measure theory, differential geometry, and algebraic topology. Therefore, you do not need to know those three subjects to participate. You are welcome to join.
Instead of discord, we will be using Matrix/Element to communicate. This messaging service offers native LaTeX integration (i.e., you can type LaTeX into a message and it will instantly render).

Winter Course in Geometric Measure Theory
Hello. There is an organized reading course in Geometric Measure Theory being held from 10 Dec to 21 Jan. This will cover sections 2.1-2.6/7 of the textbook "Geometric Measure Theory" by Herbert Federer. Once this session is completed, a new schedule will be determined to continue reading deeper into the text. Problem sets and reading assignments will be posted at the beginning of each week, to be discussed the following Saturday during a group meeting.The prerequisites for this reading course are point-set topology, linear algebra, undergraduate real analysis, and abstract algebra (standard undergraduate maths education).

Quoting one guy in particular:
>[The best study method is] retrieval practice. Read this guy's papers (Jeffrey Karpicke - they're free on his website) and you'll see that it's better than any other method. I suggest starting with his 2008 Science paper
http://learninglab.psych.purdue.edu/publications/
>also here's an interesting lecture that you might enjoy, by his PhD supervisor (who also does research in memory and learning) Henry L Roediger, who is the co-author of pic related
https://www.youtube.com/watch?v=oqae85jbfbE
>Don't want to affirm the consequent, but from anecdotal experience, after reading all their papers, I went from below-average (GPA wise) to 3rd in my year
>[...] retrieval practice works on what is called semantic memory, which is (basically) the memory of facts. If you have trouble remembering things like derivations, formulae, and empirical facts from the natural sciences, then this will help.
>For things like the application of intelligence to solve novel problems, you want to work on your procedural memory (which is basically "cognitive skill"). Here's a paper on how math ability might be related to procedural memory - but note that this area is not yet as deeply researched as retrieval practice.
http://journal.frontiersin.org/article/10.3389/fpsyg.2016.01318/full
>One other thing (this doesn't come from empirical studies, so take it with a grain of salt): A good friend of mine, who went to the international math olympiads in high school (and got silvers all the time) told me the Chinese kids had an excellent way of prepping for the olympiads.
>Any time they would get stuck on a math problem, unable to fix it, and they would be told the answer (or the solution to that particular step) later, they would take a small break and ask themselves "Where should I have figured that out from?" and then written down the explanation. And then they would basically go over the explanation and think about it for the next two or three days, once or twice a day. Basically, just burning into their memory what they should have thought of to solve that step they couldn't manage to solve then.
>And he said they told him it worked pretty well. It would make sense from a crystallized intelligence/procedural memory point of view - you're developing your math skill by constantly reminding yourself where you got stuck and what you should've thought of when you got stuck - so if that happens in the future, you're really likely to remember what you need to do.

Study methods
Don't know where to post this but I thought I'd let my mathchan friends know about this great thread I found on great studying methods https://warosu.org/sci/thread/S9152Quoting one guy in particular:
