Hey HN

I built NumberMuseum because I love those moments when you discover that a completely ordinary looking number has an extraordinary story behind it.

I really liked the story of 1729, the famous Hardy Ramanujan number. Hardy visited Ramanujan in hospital and mentioned that his taxi number, 1729, seemed rather dull. Ramanujan immediately replied that it was actually very interesting: it is the smallest number that can be expressed as the sum of two positive cubes in two different ways.

I realized there are thousands of stories like this hiding inside numbers. So NumberMuseum is my attempt to collect them. It isn't meant to be a mathematics encyclopedia. Each number is treated more like a museum exhibit, with a story to tell. I'd especially love suggestions for numbers that deserve an exhibit. If there's a number with a great story behind it, drop it in the comments I will turn it into the next one.

    I love this idea and this is a perfect example to demonstrate the concept!

    Hey! This was a great read with lots of cool examples and writing. Thanks

    putting this first — I love this concept and thank you.

    and I always hate to be “that guy” but iirc the 1729 story has a legend to itself, and the common telling may not be wholly accurate. But again, I commend this endeavor!

Doesn't this already exist?

Going through it & really enjoyed it. 2147483647 is a great exhibit. Funny how a number you recognise from debugging has a whole other life in mathematics. A museum for numbers is a lovely idea.

Fun idea, I spent longer here than I planned. How did you decide which numbers get their own room? I'd vote for 60: it's the length of the old East Asian calendar cycle (10 stems × 12 branches), which Korea still uses for things like zodiac years.
