The world is heavier (let’s say), and/or being dept chair for 2 years (which is making “getting away” impossible).

This semester, yes. Never been more mindless and crashed out. Previous semesters, not so much.

This is one of those weeks when one is more likely to receive referee reports, as reviewers finish their semesters and then want to clear their to do lists and desks.

Putnam day! Good luck to all who play.

Thanks!

Perfect for one of the things. Thanks

I might have a $150 budget to buy games for a math student lounge. (Like chess board various puzzles). Undergrad students. Maybe 15 use it, mix of 1st-4th year students.

For those who have recent experience with this:
What works really well for this type of thing?

Is that your first time for Poutine??

Yeah it’s possible I did one at school or such as a kid but just don’t remember. Think you may have been up CN tower one more time than you think. 1979, summer, was when I went up.

I guessed the stampede correctly (I also had a chance to go but did not go) but thought you had been to a territory. Guessed Inukshuk was your other one.

I’m guessing the two that you’re missing are both in the 2nd column, one near the top and one near the bottom

Maybe a couple more. In Banff, I avoid horned (and horny) very large beasts at close range. Probably all elk. It’s possible I did one of the others without realizing or remembering, I’m so old…

Cool. I’m only 17.

Or the authors tried to get it published, perhaps multiple times, and by way of bad luck (ignorant referees), the paper was always rejected.

Or there are multiple authors who no longer like each other and one is sabotaging the rest by refusing to allow it to be submitted.

A mathematician who transforms an extremely hard problem into several other problems that are also extremely hard, but each one slightly easier possibly, has had a great day.

Thank you!!

Pleased with this result, although technical :) kwnsfk27.r.eu-west-1.awstrack.me/L0/https:%2F...

Bought a bunch of high quality PPC and PPE (protection) in case these items are about to become more difficult to obtain (or at least much more expensive) in the near future….

If they attempt to enter your home or your workplace, ask for a warrant. Sometimes they will try to use other, non qualifying paperwork. They need a warrant.

You have the right to remain silent. Assert it. You have the right to a lawyer. Ask for one.

Hello maths/physics community at bluesky 👋🏻

My name is Viktor, and having been frustrated by the countless hours I spent studying and deciphering math from long, linear, exhausting paragraphs of text, I am now pioneering spatial writing to make studying and reading much friendlier for our brains.

Glad you’re feeling better!

“Happy New Year” is an annual exercise in modular arithmetic.

Further proof that everybody LOVES Mathematics.

I am excited to announce the opening of the Mathematical Art Digital Exhibition at Queens College. The exhibition features the work of 27 mathematical artists representing 10+ countries. View the exhibition at math.qc.cuny.edu/made-gallery and see the artwork, artist bios, and links to learn more.

Verify that both sides are 36x^3+66x^2+42x+9. Using x=166 as example.

Solution (2 of 2). The other key point is, with d the number of digits in x (choosing x from 1, 16, 166, 1666, etc) the right sides are:
(x)10^{2d}+(1/2)10^{2d}+(2x+1). But 6x+4=10^d. So the right sides are
(x+0.5)(6x+4)^2+(2x+1).

X^3+(2x+3)^3+(3x+2)^3 with x=166 as an example. With d the number of digits in our preferred choices of x, 10^d=6x+4 and 10^{2d}=36x^2+48x+16.

Solution. (Part 1 of 2). A key point is that the left sides of the equations have the form:
X^3+(2x+3)^3+(3x+2)^3. Also, for the x we are using (x=1, 16, 166, etc), 6x+4 is a power of 10, and therefore, so is (6x+4)^2.

Numerical pattern: 1^3+5^3+3^3=153. 16^3+50^3+33^3=165033. 166^3+500^3+333^3=166,500,333. And so on.

Testing alt text to make sure I can do it. I saw this on another social media site. If it looks like alt text works for me, I’ll post the answer in 2 replies. A picture in each reply. The other site does not have an alt text option that I know about.

I agree with this except I’ve tended to use “proposition”* for technical things that may not be of interest elsewhere. But yes, lemma is ideally a reusable neat tool. And vibes. Mostly vibes.

*I almost never use proposition.

Reviewer 1.5?

I remember in the late 1980s, my prof coming to Putnam practice and laughing about how every calc book uses trapezoids, and a Monthly article had just pointed out how rectangles using midpoints are more accurate.

I must have the wrong ap. I press “@“ at the top and nothing happens. Will probably settle here anyway so it’s not worth working on it.
