Hello and welcome, I’m Nima Amini the author of this mélange.
This blog is intended to collect a set of short (and hopefully interesting) mathematical discussions mainly accessible to an audience possessing basic mathematical literacy (broadly interpreted).
The blog mainly features mathematical puzzles that I have come across and felt necessary to write out somewhere for them not to get lost. Like good jokes, puzzles like to travel by word of mouth and cannot always be traced back to a published source (although for some reason quite a lot of nice puzzles tend to originate with Martin Gardner who wrote the Mathematical Games column in Scientific American from 1956 to 1981).
Most of the puzzles you will see here require no more knowledge than high-school mathematics, but it doesn’t necessarily mean they are easy to solve and will sometimes challenge common intuition.
For puzzles see e.g
The Laser Gun
Games of Chance
The blog also contains various other “puzzle-like” discussions that may not be directly posed as problems, but perhaps came about after watching a movie or randomly browsing the internet.
The Futurama Problem
Not That Good, Will Hunting
Lowest Unique Bid Auctions
Most solutions are my personal so if you spot any mistakes or would like to see any clarification please do let me know (virtual chocolate bars will be awarded). Likewise if you know any puzzles that you think should be on here don’t hesitate to drop me a comment and I’ll look into it.
Thanks for visiting, I hope you enjoy.
