2015 summary

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:

• Flavius Josephus and the puisi-nanoq game.
  
  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!
