5:19 AM | Zahlenmystik: welcher Feiertag ist am 3.3.?
Der 11.11. (Martinstag) in Deutschland leitet sich bekanntlich nicht von der Zahl 11, sondern von der Beisetzung Martin von Tours am 11.11.397 ab. Auch sonst sind mir keine deutschen oder europäischen Feiertage bekannt, die sich explizit auf eine Zahl beziehen. In asiatischen Ländern scheinen Zahlen und ihre Symbolik eine größere Bedeutung zu haben. In Korea…

4:55 AM | Short history of iterated prisoner’s dilemma tournaments
Nineteen Eighty — if I had to pick the year that computational modeling invaded evolutionary game theory then that would be it. In March, 1980 — exactly thirty-five years ago — was when Robert Axelrod, a professor of political science at University of Michigan, published the results of his first tournament for iterated prisoner’s dilemma […]

4:18 AM | A Little Geometry for Laying Out a Drawer Pull
I finished building a cabinet a couple of months ago just as the extreme cold arrived, which made my garage shop uninhabitable.. The ten-day forecast is now showing rising temperatures, so I am starting to think about my next cabinet construction effort. Continue reading →

3:04 AM | Can't keep up? 10 Resources to help with Arcs of Circle
A circle seems simple enough, a round plane figure with points on the border an equal distance from the center. If you are teaching arcs of circles, or trying to learn the angles of a circle you understand it can be a difficult task. In this post I will focus on helpful resources for arcs of circles. Here are 10 resources that should help. Circles and Arcs/Regents  This page defines an arc ,gives examples, and goes over the relationship between an arc and the central angle.Central Angles […]

3:00 AM | The Stable Marriage Problem (Gale-Shapley Algorithm) – An Algorithm Recognized In the 2012 Nobel Prize And Used In The Residency Match
I’ve been meaning to post about this for a while now, especially after the 2012 Nobel Prize went to Alvin Roth and Lloyd Shapley for work in matching markets. I have made a video that illustrates the Gale-Shapley algorithm and hopefully introduces many people to this wonderful part of game theory. The Stable Marriage Problem […]

2:58 AM | Things I am thinking about.

2:01 AM | A Fun Problem, and Critiquing the Reasoning of Others
So I’ve got this new thing going where, once a week, we spend class solving a few worthwhile problems. Problems totally independent of whatever unit we’re in, just math that isn’t trivial, but is accessible for as many students as possible, and pushes students to think carefully and reason clearly. The first problem we did […]

12:49 AM | Kicking Some Serious Triangle Booty
The children understand that sin, cos, and tan are side ratios. The children! They understand! They are not making ridiculous mistakes, and they can answer deeper understanding questions like, "Explain why sin(11) = cos(79)." I think right triangle trig is a frequent victim of the "First ya do this, then ya do this" treatment -- where kids can solve problems but have no idea what is going on. There's often not a ton of time for it, and it responds well to memorized procedures (in the short […]

*CHMA set is a Many that allows itself to be thought of as a One.~Georg CantorThe 62 day of the year; 62 is the smallest number that can be written as the sum of 3 distinct squares in 2 ways. (Students might try to find the smallest number that can be written as the sum of 2 distinct squares in 2 ways)In base 10, 62 is also the only number whose cube (238328) consists of 3 digits each occurring 2 timesThe digits 62 occur at the 61st & 62nd digits of phi, φ; AND The 61st & 62nd digits […]

11:47 PM | Comparing and Ordering Decimals
It is always so interesting to me what students take away in terms of strategies for doing various tasks in math class. In this particular case, ordering and comparing decimals. We all did the same shading activities, played the same comparing games, however the way this shading is applied to student thinking is so different […]

Saw this interesting tweet from Tracy Johnston Zager tonight: After going through the post I scrapped what I’d planned to do with the boys tonight and asked each of them to go through Kaplinsky’s three questions. I’m doing a geometry course with my older son this year, so I expected that these questions would be…

11:15 PM | Is Jeffreys’ prior unique?
“A striking characterisation showing the central importance of Fisher’s information in a differential framework is due to Cencov (1972), who shows that it is the only invariant Riemannian metric under symmetry conditions.” N. Polson, PhD Thesis, University of Nottingham, 1988 Following a discussion on Cross Validated, I wonder whether or not the affirmation that Jeffreys’ […]

11:11 PM | Space Diagonal
After 8 years teaching Geometry from this textbook, I finally made the lesson on Space Diagonals more interesting than saying: Do Pythag twice. Sure always do the Space Diagonal Dance, to much laughter, but the PrBL model wins. No, I don't have a video of the dance (that I know of).I happened to have brought donuts for a meeting so I had this box.I made up a story told them the legend of the Prince who made his butler leave the castle on a quest to find a delicious bread stick, the crunchy […]

10:51 PM | Who has? I have!
Have I ever mentioned that I used to also teach history? It has been since 2008, and I have always also taught math, but in my former life as high school history teacher, my classes played a variety of games aimed at learning vocabulary. They don't always translate well to math, but this one does, so long as the problems are short and can be done without paper.Step 1: Make a card set with the same number of cards as students (in classes with varying numbers of kids, some kids will hold two […]

10:30 PM | Introducing shinyStan
        As a project for Andrew’s Statistical Communication and Graphics graduate course at Columbia, a few of us (Michael Andreae, Yuanjun Gao, Dongying Song, and I) had the goal of giving RStan’s print and plot functions a makeover. We ended up getting a bit carried away and instead we designed a graphical user interface […] The post Introducing shinyStan appeared first on Statistical Modeling, Causal Inference, and Social Science.
