This is probably just some common knowledge which I am somehow unaware of... but in any case, this is a fun way to look at cotangent with the thinking of @jamestanton ’s circle-ometry.

Had great fun running the Three Colour Tower problem with @mathjamborees!
Together, we explored these questions (& uncovered quite a few more)-

Christmas in Paris!! Loving the Christmas tree at the Galeries Lafayette - the biggest upmarket department store in Europe with a beautifully decorated glass dome consisting of 10 panels with an area of over 1000 square metres. Can anyone tell me where the first photo was taken?
English
@jamestanton Draw a line above the pic, then move it down to the opposite side. One went from having 100% of dots below the line to 100% above. So, there must have been positions where 25%, 50% and 75% were above? This works as long as the line never crosses through >1 dot at any given time?
English
20 distinct points on a page (dots with zero dimension). No matter how the points are placed, is it always possible to draw three parallel lines across the page to divide the page into four regions with each region containing five dots?
English
@jamestanton Unless two dots share the same y coordinates, in which case this might not work… but surely there must be some angle from which you could use this strategy, and it would?
English
@jamestanton Rather than finding a line, my (lazy) brain wonders: a line above the pic=16 dots below the line. If one moves the line down, eventually 16 dots would be above the line. So, there must have been a position where 8 were above & 8 below? Does that work from all directions? Hmm
English
Sixteen points (dots of no dimension) are drawn on a page. Is there, for sure, to be a straight line you could draw across the page that separates the dots into two sets of eight dots, eight on each side of the line?

@tomrocksmaths @StEdmundHall A 127 km run! 🤯 (That is so cool!)

A little something I wrote for the @StEdmundHall Magazine looking back on what I've been up to this past year... In-person school talks are back with a bang, I retake my high school maths exams, and Tom Rocks Maths celebrates 100k subscribers!

Today's date, in US speak, is 11-23. Happy Bee Number day everyone!

Puzzle: Can you explain the appearance of the counts 1, 1, 2, 3, 5, 8, 13, 21,... in the family tree of a bee?

We’re on Instagram! Follow us at math_jamborees, and stay tuned for some exciting announcements coming up! (Notice anything fun about the numbers below?)

@jamestanton I think one can basically use my argument from yesterday, except replacing all of the 4s with Ks? I believe that holds as long as every NxN square with N<K does not contain equal counts of each, which I think will be the case?
English
What's the general result from yesterday's puzzle? [Imagine the infinite square grid colored with k colors in diagonal lines. (Yesterday, k=4.) For which N is an NxN square placed on the grid sure to contain equal counts of cells of each color?]
