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

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.

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

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

1:58 AM | What Makes the Golden Ratio so Golden?

Now that I’ve concluded my Golden Ratio-themed comic serial, I wanted to get into a little what the Golden Ratio actually is. Just saying that it’s some number that’s approximately 1.618, doesn’t quite do it justice. What’s so special about that number? And what makes that a ratio? Second point, first. A ratio is a comparison of two numbers, so it can cause confusion if only a single number is written, even if “to 1” is implied. What makes it so special is what is being

11:47 PM | A Little Bit of Fibonacci ...

Today's column isn't going to happen the way I wanted it to, so I'll try it for tomorrow. In the meantime, I'll leave you with this: I just finished posted a series of comics with crazy numbers in the titles after the word "part", instead of the normal "Part 1/10, Part 2/10, ..." etc. This is because those numbers were intended to be ratios, and not just any ratios, but Fibonacci number ratios. As you might have guessed from the first episode in that sequence, I would be working with
