This print is about how movements in art can be connected with contemporary #math & #physics. Specifically, the way #Cubism breaks from a single favoured perspective or absolute frame of reference & breaks down subjects into geometrical shapes from multiple points of view can be tied to advancements in non-Euclidian geometry in math & special relativity …

According to Bon Jovi's "Living on a Prayer," Gina and Tommy will make it and, in the chorus, they are half way there.

Then, when the chorus plays again, they are still half way there, that is, 3/4 of the way there. And so on.

This is called "Zeno's dichotomy paradox" and I am sorry to tell you that, no, they won't ever make it, unless they learn calculus.

Quanta: Emmy Murphy Is a Mathematician Who Finds Beauty in Flexibility

"When you came out, you chose the name Emmy, which instantly rings bells for mathematicians because of the famous early 20th-century algebraist Emmy Noether. Did you have her in mind?

So, yes, it is because of Emmy Noether. But at the time I chose the name, I was planning to leave #math. I was thinking about it as something that’s a reminder of what this previous life gave to me. She’s an inspirational figure, but a pretty obscure touchstone if you’re not in mathematics. If I’d known that I was going to stay as a #mathematician, I certainly would not have done that, because it’s pretty big shoes to fill."

@remi Using this for multiple tags and users would turn #Mastodon into a #vectorspace (linear combination of different feeds) where you can dial in your exact position of interest. "I need to #mastoart a little to the left and #math a little more towards to Z axis"

So, there is this. #Dyscalculia. Are fellow #autistics / #ActuallyAutistics. I think this also falls under #Neurodivergent?

(Long)

I don't think I fall under this entirely, at least based on how it was described in this Wikipedia article.

However, I do have the following issues:
1. I'm very poor with mental computations, ever since.

2. It takes time for me to memorise a sequence of numbers, like a 6-digit phone number (I will more likely mix it up, or forget after a few hours or a few weeks).

Pi? I can only tell you, 3.1416, and when I checked online (just now), 3.1416 is rounded. LOL

3. I'm bad with measurements, distance, volumes. Ask me how long a meter, an inch, and so on, I have no idea. I can't visualise it unless I use a reference that I already measured before. Volume? Same thing. I need a reference, and of course, it only works if the container shape are similar.

For example, I know how far 5 km is if I use a reference that I know is 5 km apart. And that also depends on if it's in a direct line, or road-based measurement.

4. When I see a die, what I see is the shape of the dots, then I know which number landed. So, say, if most people can quickly identify 9 birds sitting on pole lines, I have to literally count it.

This is why I amaze, sometimes in doubt, whenever people give estimates on crowd attendance just by looking. It doesn't make any sense to me how they did it. And whenever I check the real count, their estimates are very close!

5. And because I'm bad with mental calculations and I mix numbers, I have to repeatedly do calculations to check if I got it right (and sometimes still get it wrong).

YET, I was good at mathematics during my school years.

* Grade 6. I was a sub-teacher for our class whenever our mathematics teacher is called for other school duties (since she had multiple roles other than a math teacher).

I actually talked to our teacher privately and declined, because I already know my limitations. But, our teacher saw something in me and knew I can do it. So, I did. AND, I learned to love math.

* 4th year High School. I enjoyed a friendly competition with my classmate in speed computations.

YET, I have low major exam scores. LOL. What's even funnier, our mathematics teacher told me to teach another classmate. Guess what? He scored higher than me in that same exam. (He took it late.)

My math teacher can't help but laugh. Haha. And me, dumbfounded. She also saw something in me, and knew I can teach math. Of course, I also learned why I'm always getting low scores in major math exams, but not in daily tests. It was the whole point, she asked me to teach math to my classmate for that same major exam.

* College course: B.S. Mathematics

Going back to the article, I'm good at:

a. Logic
b. Spatial reasoning
c. Time

This is interesting. LOL. I have no idea about Dyscalculia until today.

I can't stop messing around with this new aperiodic tile that is the coolest new #math result I think I can remember in my lifetime. I love that it can be divided into the same 30-60-90 right #triangle over and over. or 4 tilings of that weirdly shaped pentagon each made up of 4 copies of the same triangle.

We need to spare OURSELVES the hypocrisy of hyper-polarized elected politicians in a country where the vast majority of people are CENTRISTS!

We can DO that IF we learn how to #PrimaryFromTheCenter !

Hello folks, my name is Jesse, and I moved here from mastodon.lol since that server is closing in May and recently the its been very unusable. Let me give you guys a quick #introduction .

I am a Romanian American currently in my 3rd year of university. I am a #trans woman using she/her pronouns. I am currently studying #compsci and #math , and I have a separate account for the latter linked on my profile (which I hope to get more active in soon). I also play video games, especially strategy games like 4X games.

Looking forward to my stay here!

"Le symbolisme est utile parce qu'il rend les choses difficiles (ceci n'est pas vrai pour les parties avancées des mathématiques, mais seulement pour les débuts). Ce que nous voulons savoir, c'est ce qui peut être déduit de quoi. [...]" – Bertrand Russell (1872-1970)

As a retired teacher, I can assure you that I would give partial credit for this answer.

A student shows a series of steps trying to solve a challenging mathematical equation. During the final attempted step, the student scribbles out the work in frustration. The student then draws a comical figure hanging from a square root sign.

Question for the #typography -minded people here: Why not put “z” with a line across the middle - or have “2” with a loop-d-loop instead?
I get that context makes it clear most of the time - except for those of us doing math on paper. I’m needing to decide so my Z’s and 2’s don’t look the same. Just curious about the typography as I consider this.

Example of Z and 2 from an American/English language math textbook. These characters look almost identical.
