2:45 AM | Viral Exam Question, Killer Robots, And Greece- Game Theory News
Welcome to this month’s “game theory in the news” post that helps students, teachers, and everyone connect game theory with current events. This month’s most popular story featured an exam question that went viral. Unfortunately the media coverage was horrible, and even the professor who asked the question slightly misinterpreted the incentives of the game. … Continue reading Viral Exam Question, Killer Robots, And Greece- Game Theory News

If you can manage to choose u and v such that u = v =x, then the answer is just (½)x^2, which is easy to remember. Oh, and add a ’+C’ or you’ll get yelled at. [xkcd]

12:15 AM | Divisibility By 7 Test Using A Graph. Why Does It Work? Sunday Puzzle
How can you tell if a number is divisible by 7? Follow the arrows in this graph! Here’s how it works. Place your finger on the circle labeled “Yes.” Then move a number of black arrows equal to the first digit (leftmost) of the number. Then move one green arrow to get to the next … Continue reading Divisibility By 7 Test Using A Graph. Why Does It Work? Sunday Puzzle

11:00 AM | Noise Riddle
For Sunday reflection: "There is an old riddle that vividly demonstrates just how noise can interfere with thinking, even when that noise is information. Imagine you are a bus driver. At the first stop of the day, nine passengers get on your bus. At the second stop, two people get off. At the third stop, four people get off, but three new people get on. What color are the bus driver's eyes

fouriestseries: Wave Equation The wave equation is a partial differential equation that describes the propagation of various types of waves. The equation appears throughout many fields in physics, including acoustics, fluid dynamics, electromagnetism, and quantum mechanics. With some modifications, it can even describe the spread of traffic jams on busy highways! The one-dimensional equation was first discovered by d’Alembert in 1746 as he studied how vibrations propagated through a […]

7:30 AM | An "Unholey" Magic Square
7/25/2015An "Unholey" Magic Square is a take off of "Unholey Primes": primes which only use digits that do not have "holes" in them: 1, 2, 3, 5, and 7.  In this one I used only the digits 1, 2, and 3 because there are 81 ways to write 4 digit numbers using only 3 different digits, and as I mentioned before a 9 x 9 Magic Square has 81 block to fill.An Order 9 "Unholey" Magic Square: […]

I'll be away and I don't know what access I'll have nor what (computer) tools I'll have available. And no one else knows how I operate any of the websites to run them in my absence.
