1:00 AM | {3,3,7} Honeycomb Meets Plane at Infinity
The {3,3,7} honeycomb is a honeycomb in 3d hyperbolic space. It is the dual of the {7,3,3} honeycomb shown last time. This image, drawn by Roice Nelson, shows the 'boundary' of the {3,3,7} honeycomb: that is, the set of points on the 'plane at infinity' that are limits of points in the {3,3,7} honeycomb.

7:35 PM | Real-World Math: Bushels of Fun
Author's Note: I started writing this yesterday (Saturday), but by the time I returned home, there wasn't time to finish it and clean it up. I worked on it this morning, but all references to "today" were really yesterday. There are four pecks in a bushel. I know this because my mother loved me a bushel and a peck. She'd tell me this all the time in song. Okay, so I was never sure what a "peck" was. Something chickens do, right? And those little kisses on the cheek, too. So four pecks would be […]

9:26 PM | How to make a paper spherical panorama
Photos usually only show a rectangular fragment of the scene when the image was taken. Typical panoramic images display more of a landscape, but they still don’t capture the whole picture. Even a 360˚ panorama only captures a horizontal circle, leaving out the ground and sky. What if you have a nice scene that you’d like to convey in full? I’ll show you how to make a spherical panorama, making use of all 4π steradians with software, a printer, and some paper. My example is an […]

2:17 AM | (x, why?) Is In TV-Tropes
As many of you are probably aware(*), there is a website called TV Tropes which details those cliches and shortcuts writers take when trying to add little plot twists or just get to the end of the story quicker. And they cover a lot more than just TV. In fact, they have pages detailing webcomics, and I've made no secret of the fact that I'd love to be listed in there or have my page appear as examples as any of the tropes pages. However, I didn't want to add my own material there. And as of […]

Salt Creek Tiger Beetle – opus 484 – Robert J Lang Origami crease patterns, plans containing intersecting lines, symmetries, and spatial subdivisions, are mnemonic guides of encoded information used to create complex origami forms. The patterns created using partially personalised syntaxes, might also be seen as algorithms. These plans might be further reduced by representing […]

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. […]

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 […]

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 […]

Submitted by TheFrankensTeam: In the model you can change the number of dots and the deviation too. If you set the “type demo” to dynamic it will make possible to analyse how the wave-pattern changes when deviation grows.
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 […]
