October 3, 2011. In search of a counterexample to the Lovász conjecture. It is a celebrated result of John Dixon, ( The probability of generating the symmetric group,. Subscription) Math. Z. 110 (1969), 199 205.) that if one choose two random permutations in the symmetric group. Uniformly (i.e. each with probability. And independently, the probability that the two permutations generate the whole group tends to. It is clear that this probability will never be greater than. Since there is a. Another approa...

Glimpses of Benoît B. Mandelbrot | mathematical musings
https://matthewkahle.wordpress.com/2012/08/21/glimpses-of-benoit-b-mandelbrot
August 21, 2012. Glimpses of Benoît B. Mandelbrot. The AMS Notices has an article this month. With personal recollections about Mandelbrot; mathematical recollections will be saved for another article. He comes across as deeply curious and knowledgeable about almost every subject imaginable. Mandelbrot gave the closing address of the 2006 International Congress of Mathematicians. He congratulated Werner. Also I wonder who he had in mind as the third Fields Medalist?

March 18, 2013. I was having fun browsing the 3D Printing marketplace Shapeways. And then I stumbled across this. Rubik’s Cube by Oskar van Deventer. And my brain exploded a little bit. Van Deventer has designed an impressive collection of cube-like puzzles. Which can only be made by 3D printing. I have an older puzzle by him called Topsy Turvy. Cube), but I like Topsy Turvy as mathematical art, and especially as a “faithful embedding” of the Mathieu group M12 in physical space. And tagged head exploded.

Abel prize for Szemerédi | mathematical musings
https://matthewkahle.wordpress.com/2012/03/27/abel-prize-for-szemeredi
March 27, 2012. Abel prize for Szemerédi. Hungarian mathematician Endre Szemerédi. Has been awarded the Abel Prize. Here is a nice interview with him. Translated to English by Zsuzsanna Dancso. Original in Hungarian here. I think Szemerédi’s sense of humor comes across well in the interview. I would like to modify my opinion — now I only regard the Fields medal and the Wolf prize as the most prestigious. This entry was posted in uncategorized. One thought on “ Abel prize for Szemerédi.

Is Benford’s law really less true now than ever? | mathematical musings
https://matthewkahle.wordpress.com/2011/10/13/is-benfords-law-really-less-true-now-than-ever
October 13, 2011. Is Benford’s law really less true now than ever? Jialan Wang, an assistant professor of finance at Washington University, has posted a fascinating note. About the observable departure from Benford’s law. Over time. I am trying to imagine any other explanation of this other than widespread fraud (or as she puts it more tactfully, “decreased reliability of accounting data). Please chime in with your own alternate explanations in the comments. This entry was posted in uncategorized. Typica...

December 12, 2011. Sneak preview: art at the Joint Mathematical Meetings. Thanks to Mikael Vejdemo-Johansson for pointing me to the online preview of mathematical art. Which will be shown at the Joint Mathematical Meetings in January 2012. Note in particular Mikael’s fantastic laser-etched Hyperbolic Coasters. I also really like these by Vladimir Bulatov.
