27.11.2025 20:47 β π 0 π 0 π¬ 0 π 0TIL the conversion ratio for miles to kilometers is very close to the golden ratio so you can estimate with the Fibonacci sequence: 5mi = 8km, 8mi=13km, etc
26.11.2025 14:40 β π 2 π 0 π¬ 0 π 0Another failed math pangram, although Iβll concede this one for being proper.
26.11.2025 14:36 β π 2 π 0 π¬ 0 π 0I am at an age where βIβm exhausted because I drank too much last nightβ means I drank a root beer after 7pm and had to get up three times to pee.
16.11.2025 16:27 β π 1 π 0 π¬ 0 π 0Yep. I teach 9 hours a week, therefore I work 9 hours a week. It's annoying with family, but a real problem that politicians think this too.

03.11.2025 14:54 β π 0 π 0 π¬ 0 π 0Boring answer, but Cayleyβs Theorem. It was a revelation to me as a student that all groups live in symmetric groups.
03.11.2025 03:55 β π 2 π 0 π¬ 0 π 0Not great to save the porn years for last.

23.10.2025 11:23 β π 0 π 0 π¬ 0 π 0Handy example I dumb-lucked into today as I had to conjure a vector angle problem on the fly: (1,2) and (3,1) make at a 45-degree angle.
20.10.2025 18:55 β π 0 π 1 π¬ 0 π 0This week gave me an idea for a stats problem: determine whether βmissing class for a funeralβ and βthere is an exam in classβ are independent events. I have some data they can use.

17.10.2025 00:37 β π 1 π 0 π¬ 0 π 0I often wonder how much good we could do for the world if we just... didn't mow our damn lawns. Or even just mowed them much less often. Such a waste of gas and time.

Whatβs is happening at this IHOP?
06.10.2025 23:36 β π 1 π 0 π¬ 0 π 0Has anyone had any disgruntled students from their past stir up trouble lately?
I got one from almost a decade ago and I wonder if it's because it's open season on professors right now and he was disappointed that I have no political posts on my socials to report. #teachmath
I feel that. And Iβm hearing a lot more of this lately. I think something has changed.

19.09.2025 01:53 β π 1 π 0 π¬ 0 π 0My current favorite show just triggered my pet peeve: 3.141459... is not some secret code to the universe. If you must reference pi when you make alien contact, use the continued fraction expansion in case they don't have 10 fingers.
