I’ve shared a few of Vi Hart’s videos before, they are a gift to anyone who wants to make math fun because they are fun and about math. She made a documentary with ebstudioslive about how she makes he videos then she made a video about how he made that video, and all her other videos.
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.
UPDATE: Not that anyone has been following this but I’ve found the image. I saved it to my iPad and it popped up in Dropbox’s camera uploads when I plugged my iPad in! Woo! Still no idea where I found the image though.
I could spend hours trying to find out what the japanese in this article is trying to say, or I can infer from the imagery that it is trying to teach you the optimal angles for staring up a girls skirt while walking up a set of stairs.
I wish I knew what book or magazine this came from, I’m sure it would be a gold mine…
While I object to the use of the word “nerd” I love the concept of this Nerd Baby Colouring in Book (Yes I spelt “colouring” correctly). If/when I have kids they will be getting a copy of this book by Tiffan Yard it seems to me that there is a whole industry based on selling stuff like this to relatively geeky parents as a couple of days ago I spotted another book entitled Introductory Calculus For Infants by Omi M. Inouye which is available at ThinkGeek:
I reckon there is a huge market for this and I’m going to start work on “The Very Hungry Paramecium” and the “Amoeba Who Was Wfraid Of The Dark” immediately…
