Newcastle MathsJam February 2012 Recap
February’s MathsJam was loads of fun! We had a record attendance of 14 cheery people who just about managed to fit around the biggest table in the Charles Grey.
After last month’s puzzlocalypse, which left me for over a week unable to count the toes on my feet, I wanted to have a nice relaxed evening.

Alex the parrot could count to eight
The Nature News Blog reports on a new addition to the non-human numerism literature:
Even in death, the world’s most accomplished parrot continues to amaze. The final experiments involving Alex – a grey parrot (Psittacus eithacus) trained to count objects – have just been published.
They show that Alex could accurately add together Arabic numerals to a sum of eight and three sets of objects, putting his mathematical abilities on par with (and maybe beyond) those of chimpanzees and other non-human primates. The work was just published in the journal Animal Cognition.

Interesting Esoterica Summation
I feel like it’s time to do another summary of my recent additions to the Interesting Esoterica collection.
A reminder of what it’s all about: every now and then I encounter a paper or a book or an article that grabs my interest but isn’t directly useful for anything. It might be about some niche sub-sub-subtopic I’ve never heard of, or it might talk about something old from a new angle, or it might just have a funny title. I put these things in my Interesting Esoterica collection on Mendeley.
In this post the titles are links to the original sources, and I try to add some interpretation or explanation of why I think each thing is interesting below the abstract.

MATH PROBLEMS?
Maths in the City posted this on twitter:
In order to make a number we can call, we need both of \[n=(10x)(13i^2)\] and \[m=\frac{\sin(xy)}{2.362x}\] to be integers.
