5:00 AM | Check Your Solutions

(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.Extra for solution sets. The "Eggoids" appeared very early on in the strip when I needed something to be the embodiment of a mathematical formula. I didn't want to have just an equation with eyes and a mouth, or even a talking equation with no facial features at all. I think I've done both in the past near-1000 strips. You know, I did think of doing some kind of "discount" 9.95 joke, but I didn't want to get

I am told the beer scene was completely different in the 1980s. Most places offered Budweiser or Miller. If you were lucky, you could get a Heineken, Sam Adams, or a Guinness. Today, you can get a better selection at a train station. At Chicago’s Union Station you can get at least 10 craft beers, … Continue reading Why Craft Brewers Are Turning Beer Into Wine – Game Theory Tuesdays Case Study

3:15 PM | Loving... Mathematics

For today, just a bit of humor lifted verbatim from Jim Henle's short, delightful, new volume, "The Proof and the Pudding," a fun book which, rather to my surprise, I'm loving (...a review sometime in the future):
"A mathematician was trying to decide: Should I get married? Or should I take a lover? The mathematician consulted a lawyer.'By all means take a lover. The legal complications of

A Long Introductory Note I wrote this puzzle with the characters Alice, Bob and Charlie.

The Baron's last game pitted Sir R----- against him in a duel of dice. At each turn the Baron would add a token to a pile, initially containing four tokens, and he would roll a six sided die and Sir R----- would roll a four sided die. If Sir R-----'s roll equalled or exceeded the Baron's he could remove two tokens from the pile. The game cost Sir R----- a single coin to play and should he have ever exhausted the tokens would have won four coins from the Baron.

11:15 AM | Geometry and Physical Space

Today's 'Sunday reflection' from physicist Carl Rovelli (via John Brockman's "This Idea Must Die")... in which I get to learn the word, "pullulating"!:
"We will continue to use geometry as a useful branch of mathematics, but it's time to abandon the longstanding idea of geometry as the description of physical space. The idea that geometry is the description of physical space is ingrained in us

11:37 PM | Leonard Euler

This week we celebrated Euler’s birthday on 15th and I thought I need to write something about him. In my (almost) 4 years of university I have heard his name a lot of time. And this is a thing especially because at most of my courses the teachers don’t say anything about the mathematicians that […]

5:00 AM | Happy Math

(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.I've done this. No, it doesn't make it better. I've also had some interesting conversations online with people who absolutely hate, despise, loathe, abhor and generally wish to do all sorts of ill deeds to long division of all sorts. And that's just the teachers! Come back often for more funny math and geeky comics.

6:57 PM | Games: for sport or curiosity

I think it's time to write my experiences and insights about gaming (again). As for myself, I like to play with GNU Chess or GNU Go in these days, because mastering these games could lead to success in real life too. As for chess, I do not like that the starting position is always the same, and for this reason, experienced players have a great advantage due to familiarity with the openings. In chess, the actual position can be evaluated by computers quite well, so the position gets a numeric

Stupiti che 1 non sia primo? Scopriamo insieme perché è "solo" l'unità!Abbiamo già visto come, partendo dai numeri primi, si possa sviluppare un discorso più o meno approfondito sulle fondamenta matematiche. Altrettanto fondamentale, però, si rivela provare a rispondere alla domanda su quale sia il numero primo più piccolo. E', infatti, abbastanza noto come il numero 1 sia stato ora inserito ora escluso dalla lista dei numeri primi, ottenendo in alcuni casi lo status di più piccolo tra […]
