Some More Math Fun

As an answer to George Hart's Möbius Bagel, Serious Eats has constructed a Möbius Doughnut


Then I saw a picture on Wired Science and thought that somebody had knitted a mathematical equation in 3-D.

It turned out that it was a Mandelbulb, a 3-D visualisation of a fractal called a Mandelbrot set. After seeing some videos like the next one, I still think that this is just like a cool knitting work...

Here is an example from a Finnish knitting blog nekkisneuleet. Using different patterns, someone could really knit a visualisation. Too bad I am not good in designing...


Finally Makezine led me to some really impressive polyhedra made of playing cards, again by George Hart

When Your Math Papers Come Alive

Last night I was listening The Drill Down, a podcast which is well known among the Diggers. I don't much listen to it nowadays live after they changed the time they send the podcast. Now it comes out in the middle of the night for me (1.00 am Monday morning) and if I have to work the next day, I don't want to to stay up that late. Anyway my TV was open on the background and it was on The Voice TV Finland, playing some music videos. Suddenly one of the videos caught my attention even though I had my headset on for listening to the podcast. The video is just so fascinating and the song is not bad either. My papers live also their own life but usually the other way around. Numbers and calculations start crawling among the other text and pictures :)

Puzzles and Nokia N900

I am a fan of all kind of gadgets and I am not very good in texting or surfing the web with my mobile phone, Nokia E90, which I bought last year. When Nokia announced the new model N900, I decided I want to have it.

I just love the phone. Web pages open fast and I have multiple desktops to save the applications and favourites I use. Everything I need I can choose with my fingertip. I am still learning to use all the features, but one of my first was to check Conceptis website. The start was a bit tricky but with persistence I finally got a result:

Now I have learned to adjust the size of the screen and to use the pen which came with the phone and I started solving a Hitori. The puzzle was a small and easy one, and I got it finished in less than 5 minutes!

What is special about this? I don't need any applications. I can go to my best website and solve the puzzles there. The trick is the Adobe Flash™ 9.4 support my phone has. The prevoius one did not show even the thumbnails of the puzzles.

Inspired By Mathematics

As in honour of my Christmas holiday I found two mathematics inspired items yesterday.

This ring is inspired by the Fibonacci sequence 1,1,2,3,... The pattern of the beads is the beginning of the sequence.
