(Click on the comic if you can't see the full image.) (C)Copyright 2014, C. Burke.Have you ever known anyone who just does the chant waiting for someone to jump in with the words. Have you ever been that person? Flowcharting: a lost art. It doesn't have to be complicated, but ti shouldn't be too "clever", either. Mostly, it should be readable so people in your audience can understand it (not everyone involved in a project is an expert coder). Readability, and easy understanding, are why I […]

For example, along the row beginning with the letter "h", the darkest hue, represents the highest probability (47.42%), is for the letter that most likely follows, which is "e".The most likely letter to follow "d" is "-", indicating that the most likely choice is no single letter, but instead "nothing". So that "d" most likely is at the […]

(Click on the comic if you can't see the full image.) (C)Copyright 2014, C. Burke.I may make a poster of this even if my students get neither the math nor the TV reference. They need to learn about both. As far as the math goes, there are two points on the co-ordinate plane to start. Let's call the first one Point A, with coordinates (-5, 2). The other point we'll call Point B, was at (2, 4) -- so it wasn't a rotational image of Point A. Point B has up and moved itself, which points don't […]

Unrolling these circles gives fills a triangle with base 2 π r and height r (where r is the radius of the filled disk). Such a triangle has area π r2. This does not serve as a complete proof for why this is the area of a circle, but can give you some intuition for why it should be. [code]

mister-wunderkammer: Counting in binary Instead of counting up to five on each hand, a binary system can be used to count up to 31 on one hand, and up to 1023 on two hands. This is done by using your fingers to represent increasing numbers, multiplying by two each time. Once the numbers 1, 2, 4, 8 and 16 are assigned to the fingers, as above, different numbers can be represented by raising or tucking in the fingers. A raised finger represents its number being “on”, whereas a lowered […]
