Easy to construct, 18×18 magic square.
If you take the decimal expansion of 1/19, 2/19… up to 18/19, and write out the first 18 digits of the decimal expansion of each, you get:
0 5 2 6 3 1 5 7 8 9 4 7 3 6 8 4 2 1 | 81 1 0 5 2 6 3 1 5 7 8 9 4 7 3 6 8 4 2 | 81 1 5 7 8 9 4 7 3 6 8 4 2 1 0 5 2 6 3 | 81 2 1 0 5 2 6 3 1 5 7 8 9 4 7 3 6 8 4 | 81 2 6 3 1 5 7 8 9 4 7 3 6 8 4 2 1 0 5 | 81 3 1 5 7 8 9 4 7 3 6 8 4 2 1 0 5 2 6 | 81 3 6 8 4 2 1 0 5 2 6 3 1 5 7 8 9 4 7 | 81 4 2 1 0 5 2 6 3 1 5 7 8 9 4 7 3 6 8 | 81 4 7 3 6 8 4 2 1 0 5 2 6 3 1 5 7 8 9 | 81 5 2 6 3 1 5 7 8 9 4 7 3 6 8 4 2 1 0 | 81 5 7 8 9 4 7 3 6 8 4 2 1 0 5 2 6 3 1 | 81 6 3 1 5 7 8 9 4 7 3 6 8 4 2 1 0 5 2 | 81 6 8 4 2 1 0 5 2 6 3 1 5 7 8 9 4 7 3 | 81 7 3 6 8 4 2 1 0 5 2 6 3 1 5 7 8 9 4 | 81 7 8 9 4 7 3 6 8 4 2 1 0 5 2 6 3 1 5 | 81 8 4 2 1 0 5 2 6 3 1 5 7 8 9 4 7 3 6 | 81 8 9 4 7 3 6 8 4 2 1 0 5 2 6 3 1 5 7 | 81 9 4 7 3 6 8 4 2 1 0 5 2 6 3 1 5 7 8 | 81 ------------------------------------------------------+ 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81 81
The sum of the rows, colums, and it turns out, the main diagonals is 81, which means that it’s a magic square. It’s not hard to see why the rows and columns are sum to the same, but the diagonals are a bit trickier. Anyway, just something to think about.
I suspect the world would be better if that percentage were even greater.
Apparently 15% of all web traffic is cat related. There's no reason for Brainwagon be any different.
Thanks Mal! I'm trying to reclaim the time that I was using doom scrolling and writing pointless political diatribes on…
Brainwagons back! I can't help you with a job, not least because I'm on the other side of our little…
Congrats, glad to hear all is well.
