1:11 AM | The "mini" comics? Good idea or just quick filler?
I didn't get any response to yesterday's mini-comic, but then, I rarely do. (And not to complain because I'm happy to get comments, but it's generally the same 2 or 3 people.) When I did a little analysis of the previous comics and saw that a year was going by before I reached the next 100th comic, I realized something was wrong. It's taking more and more time that I don't seem to have. And unless I want it to turn into a soap opera among the teachers, the jokes are getting harder to write. […]

2:09 PM | Ice Bucket Efficiency
If you have been living on Planet Earth with an internet connection during the past month, then you can't fail to have noticed the precious bandwidth that has been devoted to streaming videos of people being soaked by a bucket of (allegedly) ice-cold water: The [insert chosen charity here] Ice-Bucket Challenge.Dubbia is for WaterIt is one of those extraordinary phenomena that transcends age, race, creed, and sanity. Everybody but everybody is getting in on the action. With the new school term […]

ted: What do leopard spots, striped marine angelfish, and sand dune ripples have in common? Their patterns are self-organizing Turing systems! Discovered by Alan Turing in the 1950s, these repeating natural patterns can be created by the interaction of two things that spread at different speeds, one faster than the other. See how scientists are applying Turing’s theories today. Gifs are from Creative Commons videos by Jonathan McCabe. I knew that name was familiar! Alan Turing is […]

12:30 AM | Introduction to Incompleteness
"Incompleteness is one of the most beautiful and profound proofs that I’ve ever seen. If you’re at all interested in mathematics, it’s something that’s worth taking the effort to understand."  -- Mark Chu-Carroll  Mark Chu-Carroll (of "Good Math, Bad Math") is in the process of re-posting his own splendid discussion/explanation of Gödelian Incompleteness this week. If it's a subject that interests you, or you've always wanted a detailed introduction, his first three posts […]

12:00 PM | Common Core Common Sense: Myths About the Standards, Part 4
In recent months, there’s been a tremendous amount of buzz regarding an educational change called Common Core. And a ton of that buzz perpetuates down-right false information. There’s so much to say about this that I’ve developed a five-part series debunking these myths — or outright lies, if you’re being cynical. This is the fourth in that […]

7:52 AM | Small gaps between large gaps between primes results
The big news last year was the quest to find a lower bound for the gap between pairs of large primes, started by Yitang Zhang and carried on chiefly by Terry Tao and the fresh-faced James Maynard. Now that progress on the twin prime conjecture has slowed down, they’ve both turned their attentions toward the opposite question:... Read more »

5:00 AM | (x, why?) Mini: Potential
(Click on the comic if you can't see the full image.) (C)Copyright 2014, C. Burke.Would becoming purely kinetic be realizing your potential? This is a new thing that I'm trying, (x, why?) minis. "Mini" as in "minimum", so it has a mathematical context, along with "minimum artwork, background and coloring". I thought about calling them "quickies", but that lacked the math connection and, frankly, this wasn't as quick as I would have liked. Happy Joe Burke Day!, the anniversary of my father's […]

This is the current installment of the monthly series “Game Theory in the News.” My hope is to highlight stories that can be used as case studies in the classroom, both so students can see how to apply game theory and so teachers can make class material easier to relate to. You can get these […]

12:53 AM | N-RN.3 (Real Number System) - Irrational Behavior
A short entry for tonight. Moving on to another Common Core Algebra standard brings me to N-RN.3, which reads Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational. The key word here is "explain". Before we do that, let's establish that the rest of the standard is true: if you add two rational numbers, you will get an […]

9:40 AM | "Flawless Harmony" Puzzle
Source: AUSTMS Puzzle Corner 35 Problem: Call a nine-digit number flawless if it has all the digits from 1 to 9 in some order. An unordered pair of flawless numbers is called harmonious if they sum to 987654321. Note that (a, b) and (b, a) are considered to be the same unordered pair.Without resorting to an exhaustive search, prove that the number of harmonious pairs is odd.

ryanandmath: Imagine you wanted to measure the coastline of Great Britain. You might remember from calculus that straight lines can make a pretty good approximation of curves, so you decide that you’re going to estimate the length of the coast using straight lines of the length of 100km (not a very good estimate, but it’s a start). You finish, and you come up with a total costal length of 2800km. And you’re pretty happy. Now, you have a friend who also for some reason wants to […]

Two major highlights of the trip were the flights in the DC-8 and the amazing Sarpians + faculty. So here is an album of the two of them together :)The Don taking a quick nap while his group collects air samplesJ-Pop clearly enjoying his flightHow Kira and Diana became best friendsThis guy rocked!
