Watching a PhD mathematician struggle to get 17^2 was reassuring.
-
*Sees first two primes don’t follow his rule *Calls them sub primes.

I like how hard it was for him to do the math in his head. It reminds me of the saying "the more math you know, the harder it is to do math"
-
4:31 Matt received weapons of math instruction
-
Video starts with Matt trying to Parker square 17.
-
0:58 I love how he rewrote the 139 to make it read 289 after he scored out that calculation so he could say "Dammit I was right". Parker convincing.
-
It amazing how matt did all the mental maths perfectly and then said 170 +70 AND 49 is somehow less than the original
-
I like how the four categories from your proof also show up in the "easier" proof. Either the multiple of 4 is above or below the prime, and either the multiple of 3 is above or below the prime, giving four possibilities that directly correspond to your categories.
-
17^2=139 I think I just witnessed Parker Squaring.
-
3*3 is one more than 8, 1/3 of 24. 2*2 is one more than 3, 1/8 of 24. Pretty neat!
-
Matt: There is a pattern with prime squares, they are all multiples of 24 plus 1. All? Matt: Almost all. So it's a parker squares pattern then...
-
Nice sneaky edit of the 139 on the paper
-
“I like to argue that 2 and 3 are not real primes” Goodbye, fundamental theorem of arithmetic
-
Only three things are certain: Death, Taxes, and Parker Square jokes.
-
That second proof gave me chills down my spine when I saw where it was going, you might even say it was an Amazingly Satisfying Mathematical Result
-
I just love your guests, every one of them. Listening to them is such a treat. Thanks
-
17²=139, nice to start the video with a parker equation!
-
17^2=139. C'mon. Now you're just begging us to make a Parker Square joke.
-
I am currently doing my degree in maths and one of the things we need to prove is that all primes squared (above 3) are one more than a multiple of 6, and I know how to prove it because of your video. love you matt!!!!
