one math phd, 3000 likes, and ZERO JOB OFFERS
apparently being overqualified is an actual thing why didn’t i believe them
playgirI garvi@garvvee
the best time to start a phd is right now. the worst time to start a phd is 5 years ago.

The mathematician's lazy path: principle of least action in action.
Oxford's Philip Maini drops the truth bomb: "To be a really good mathematician you have to be lazy."

@AlexAndBooks_ Sentence so good I have to take a picture or screenshot it for later, despite knowing it will be lost in the unorganized mess of my gallery

One of the best feelings from reading is when you find a sentence so good that you have to close the book and stare at the wall for a minute.

Never underestimate how much time and effort you can waste by trying to automate a process you do not understand manually.

@TaliaRinger Intuition guides Theory vs Theory guides Intuition is the "Which comes first, the chicken or the egg?" of Mathematical Learning.
English
I think these things helped give some high school kids intuition but my brain just panicked because I still couldn't unpack what they actually meant. Until Real Analysis in college which I found very easy. Got a C- in AP Calc BC and an A in Real Analysis I and II

Some meaningless phrases from calculus: -integrals are just areas under curves -derivatives are slopes -a continuous function is one that you can draw without lifting your pencil -limits are about getting arbitrarily close to a value

@abdimoalim_ How many people will get stuck re-inventing Boolean Algebra?

Only a few individuals would be able to reconstruct a computer from first principles in the event of a civilizational collapse.

People often say mathematicians are not afraid of anything—except one thing: the Collatz Conjecture.
It is one of the most famous unsolved mysteries in mathematics.
Here’s how it works:
Pick any positive number.
If the number is odd, multiply it by 3 and add 1.
If the number is even, divide it by 2.
Now repeat this process again and again.
For example, start with 7:
7 is odd → 3×7 + 1 = 22
22 is even → 22 ÷ 2 = 11
11 is odd → 3×11 + 1 = 34
…and so on we get:
7 → 22 → 11 → 34 → 17 → 52 → 26 → 13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → 1
The surprising claim is this: no matter which number you start with, you will always eventually reach 1.
It sounds simple, but no one has been able to prove that it is true for all numbers. That’s why it remains a mystery.

@zermeloztt @AngusMacnamara @SokobanHero @mathandcobb A guy who found a way to interpret arithmetic with only 0s, 1s, and basic logic was overlooked because it seemed meaningless. Skip forward 100 years, it became the core of bitwise and the computers we use now. Boolean Algebra came almost 90 years before we used it for anything.
English
@zermeloztt @AngusMacnamara @SokobanHero @mathandcobb I enjoy finding and trying to explain connections between fields in whatever I can, but some people doing their own thing without care is important, and forcing people to rigidly work only for the benefit of 'real world' discovery sucks ass.

NOW: 🇺🇸 US HAS STARTED REFUNDING $175,000,000,000.00 IN TARIFF REVENUE.
Consumers paid the tariffs, but businesses are getting the refunds.

100 MHz was more than adequate to run a GUI. At 100 fps, we had a budget of 1 million cycles per frame.
At 4 GHz with 8 cores, no UI task should ever take more than 1 ms. We have 320 MHz per frame available.
What the actual fuck is Microsoft doing these days?!

I worked on the XP run dialog. I'm a grizzled old man now, barely recognizable in the mirror, but even I think 94ms is a long-assed time to wait for a dialog to open.

@Ken_Stonger @Fintech03 Honestly, this is just a large percentage of people in math. I remember going to a conference and a guy was handing out a custom magic square worksheet. I tried it and listened as he happily explained them more in depth until talks started, he was super passionate.

Feynman once walked into the math department at Caltech & challenged the mathematicians to a duel.
He asked them to name any theorem, no matter how complex, & promised he could explain it using common sense & basic physics.
They gave him the Banach-Tarski Paradox (which says you can cut a ball into pieces & reassemble them into 2 identical balls). Feynman looked at it & dismissed it because no such material exists in nature. To him, if the math did not describe an asset in the real world, it was just accounting fluff :))

@rossiadam Teacher did wrong by not providing any feedback on the specific wrong # or the correct answer for review. This was setting up adding 0 and/or splitting a number up to achieve something in context. 2 of the correct numbers, 8 and 2, are already there, just 9 should have been 7.

For those of you that are new to following we here on X…
I wrote this note on my son Nick’s homework when he was a student at Nysmith Elementary years ago.
The teacher took a pic and posted it. It has been shared across social media millions of times.
It will long outlive me.

This is stupid. Just add the damn numbers or memorize it. What are we even doing?

I realized nobody actually knows what they’re doing. Everyone is just figuring it out as they go . You don’t need permission, qualifications, or expertise -you can just do things.
