I thought a lot about quadtrees and space filling curves and the connections between them during my doctoral work. Google has a great spacial indexing library that uses some of the same concepts :-) 
Google's S2 library is a real treasure, not only due to its capabilities for spatial indexing but also because it is a library that was released more than 4

The students' test distribution doesn't have to look like a bell curve.
http://academia.stackexchange.com/questions/18747/understanding-an-abnormal-grade-distribution
I have three years of experience teaching as part of a team (many teachers, some with more experience, agreeing on a syllabus and preparing the tests together), but this year is the first time I am fully in charge of some courses. After grading the mid-term exam for one of my class, I noticed I had a weird grade distribution: (If this is useful, there are 24 grades, the set of grades is { 1.2, 1.4, 1.4, 1.9, 2.0, 2.3, 2.6, 2.6, 3.4, 4.2, 4.2, 4...

Social scientists working on a decades-long population study have recently concluded that every single living resident of the United States suffers from a condition known as imposter syndrome, a psychological phenomenon in which people are unable to internalize their accomplishments, except for you, an actual fraud who is almost certainly on the verge of being found out by the people who only think they love and respect you any day now.
Everyone suffers from imposter syndrome except for you, the only real fraud left.

Youtube is promoting Geek Week by highlighting popular YouTube Channels to all manners of geekery and nerddom. Today's riddle, according to YouTube statement, features "seashells, pine cones, artichokes, pineapples." All of these naturally found objects have a number of spirals that relate back to...

For maximum efficiency, don't allocate resources until you need them.

Solve puzzles and play games for science! Or for me. Whichever you prefer. :)

I'm doing research on automatic difficulty assessment of puzzle games. For this research, we need data about the difficulty of puzzles as perceived by real players, and we are currently performing a user study. One of my students has re-implemented three popular puzzle games. We need people to play the games, and for each level estimate its difficulty. You can play the games in your browser, either on a PC or a mobile device.

If you would like to help, please follow the link below.

Thanks!

Difficulty Assessment in Puzzle Games. Thank you for participating in the user study for my thesis. The goal of this research is to create an algorithm that automatically rates the difficulty of puzzle game levels. To do this, we first need to know how humans rate the difficulty.

I always have trouble describing what I do to people without a mathematical background. In preparing the introduction for my dissertation, I came across the following paragraph, which I think goes a long way towards explaining what I do in a simple and general way:

Ever since computers are used for solving problems, people have tried to write programs that solve these problems as efficiently as possible. Two types of efficiency are particularly important: (i) the amount of time required for running the program and, hence, for solving the problem, and (ii) the amount of storage required. In the early years of computing, efficiency was generally obtained by "clever" programming and coding tricks. Soon people became aware of the need for systematic methods for solving problems and for a mathematical apparatus for analyzing such methods and solutions. The field of "Algorithm design and analysis" was born.
