Hexaflexagons!

Hexaflexagons are hexagonal folded bits of paper that can be inverted onto themselves to show multiple faces. Watch the video for more information, the reason this phenomenon happens is that the Hexaflexagons are a flattened out folded up Möbius strip. I had a go at this yesterday using patterns I found on the flexagon portal it’s quite simple.

I think these would make for some pretty cool business cards.

Vihart actually posts quite a lot of cool maths related videos, it’s worth checking them out.

Useless Superpower: Selective Telepathy

I had an idea this morning of a super power that would not only be completely useless but would also be a little annoying. What if you were telepathic but the only thoughts you could hear were other people’s earworms?

For the uninformed here is the definition of an earworm from Wikipedia:

An earworm is a piece of music that sticks in one’s mind so that one seems to hear it, even when it is not being played. Other phrases used to describe this include musical imagery repetition and involuntary musical imagery. The phenomenon is common in normal life and so may be distinguished from brain damage which results in palinacousis.

I think it might be an amusing aside to a character in a story, they experience some really weird incident and gain a super power but it’s completely rubbish… Maybe I’ve been watching too much Misfits…

Can anyone see any benefit to this super power? Or can you think of a more rubbish/pointless power?

Feel free to leave comments.
Incidentally the reason I put the definition of an earworm in this post is because when I told one of my colleagues of the idea he thought I was talking about this:
