A summary of the posts issued in 2015. I hope you enjoyed them all.
First of all, I want to thank you for being there one more year.
In this 12 months we have practised some new mathematical issues. I hope you have enjoyed them.
Here you have a list of the posts of this year 2015:
We started the year in Greenland, among seals and bears, with a puzzle about modular arithmetic in which we discovered the Flavius Josephus problem.
A galactic prize.
Later we traveled to the far west, to try to build enormous numbers with a few figures. This entry was rewarded with the first prize of the mathematical Spanish contest "Edición 6.2 Número Pi" del Carnaval de Matemáticas.
The awkward question.
We went to Guanzhong, in China, where we learnt some mathematical methods to ask questions about awkward issues.
Sabotage in the stores.
We returned to Madrid, to face a problem of simplification.
Spirals and roulettes.
And to close the season, we take a quick look at the spirals and helices at Monaco.
I hope that next year you'll also visit my blog. And that you will enjoy my new issues. Thank you very much. I wish you a happy 2016!
