Wrong, but Useful episode 41
We discussed the idea of some numbers being ‘nicer’ than others. This really is a bit a weird topic and hard to describe but I think we all have an inner feeling of which numbers seem nice. You may have heard someone say, “ooh, let’s make it a nice, round number” for example. Alex Bellos has written about how people have favourite numbers and that the most popular choice is 7. My current favourite number is Belphegor’s Prime:
3s, 6s, and 9s
I also talked about taking a string of 3s (or 6s or 9s) and squaring it. See what happens.
33333² = 1111088889
We talked about when 15 = 16 or when 15 is a square number:
Some questions that came from twitter:
- What are bounds for the radius of a kiev?
- What’s the minimum number of kievs you might get in a bag?
- How can they be so precise about the amount of salt in a kiev that seem to vary in size?
- If the * is a power, what does it equal?
- What percentage extra did I get?
- How many chickens were harmed to make this bag?
A game or two (Two. It’s definitely two.)
