65 = 01000001β
97 = 01100001β
I've done a lot of (very simple) programming, and I've always had to look those numbers up because I could never remember them. π€¦

An infinite set of regular-pentagonal rooms, each connected to five others, one door on each side
The answer to the unit square question is on the boring side, but nudge one of the four vertices even just a little bit, and it becomes far from boring!
24.07.2025 20:45 β π 1 π 0 π¬ 1 π 0How do I come up with "original" (as in, new-to-me) math problems?
It always starts with wondering.
Like: What if a set π β βΒ² had the property that if points A and B are in π, then so is the midpoint of segment AB?
Then I just start wondering things about π.
Curiosity is such a powerful engine.
#TryMathsLive is amazing, and more mathematicians and math educators should participate!

Applies to many tasks, such as:
- putting away groceries
- folding and putting away clean laundry
- cleaning the kitchen
- cleaning pretty much any room in the house

No, no, you've got it. I guess I'm just not clear where the 3/8 is coming from.
21.07.2025 21:17 β π 0 π 0 π¬ 1 π 0Don't A going to B and A going to C both yield a crease that divides the square in half?
21.07.2025 20:10 β π 0 π 0 π¬ 1 π 0Square ABCD is to be folded once so that point A lies somewhere on segment BC, then unfolded, leaving a crease. That crease will divide the square into two pieces.
What proportion of the square's area consists of points that are guaranteed to be on the same piece as A?
Here's 9 consecutive primes that end in a '1':
36539311
36539381
36539401

Are there arbitrarily long runs of consecutive primes that end in a '1'?
#WonderWithMe #iTeachMath #MathSky #math #mathchat
Take the infinite sequence of primes, and reduce them all modulo some integer m>2.
Are there runs of identical terms of arbitrary length in this new sequence?
For example, is there a run of 100 consecutive primes that are all congruent to each other mod 67?
My conjecture: π€·ββοΈ Sure!
Rectangular piece of paper ABCD has a perimeter of 44 units.
If you fold the rectangle once so that point A lands on the midpoint of BC, then the perimeter of the resulting polygon (considering only the exterior outline) is 39 units.
How long is the crease?

15.07.2025 13:11 β π 11 π 0 π¬ 3 π 0Three math ed ideas that have stuck with me and guided me for years:
Dan Meyer: If [math idea] is the aspirin, how do we create the headache?
Francis Su #1: Whom do we allow to see the "secret menu" of math?
Francis Su #2: Does your math class feel like domination, or freedom?
(links below)
Is it possible to start with a polygon, fold it completely over a single crease, and have the new polygon that its outline forms have a perimeter greater than its original perimeter?
