This is a mini-series on how revenue sharing and operations research are linked. You might want to read part 1 on the specific business problem I was solving. In this part, I’ll be telling you about the maths behind the business solution. But first, I have to tell you about a couple of maths concepts. […]
Back when I was writing my thesis, I came across this abbreviation: a.e. It took me a while, but I eventually found that it meant almost every. This might have been almost everywhere in measure theory, but I don’t think so. I seem to recall just “almost every”. Almost every what, you ask? Well, I […]
So a blog reader, Michael Gmirkin, sent me an in-depth email about the possibility of the existence of a super equation that can describe any regular polygon. I wasn’t sure. For reference, you might want to check out these 2 blog posts about the equation for a square: question, answer. I was going to just […]
I made this video because I’ve always been skeptical about reports (such as population census and surveys) with the average as the only statistical measurement.
Adrian Colomitchi wrote me an email about an article I wrote. It turns out that I was wrong about the inflection point section. I was trying to figure out what Timo meant by “loop tips”, and I figured it could be an inflection point. So here’s how Adrian describes inflection points: If you drive or […]
John Cook wrote an article on where to wait for an elevator. Where do you wait so you walk the minimum distance to the elevator? Read his article for the full explanation and solution. Here’s a pictorial summary of the solution: The problem was from a paper written by James Handley (and collaborated with others). […]
And here I thought bit shifts were already very simple to understand. I was actually hoping that the video would shed some light on the Udja Eye thing, but it didn’t… oh well.
Pierce Brown created a beautiful infographic on the Fibonacci sequence. It has rabbits, sea shells and sunflowers. Go take a look.
I was reading this post by Dan Meyer on pseudocontext in maths problems. If we invite pseudocontext in our classrooms without condition, it becomes harder and harder to tell the difference between the real and the unreal. Back when I was young, a lot of maths problems made little sense to me. In those days, […]
The 67th Carnival of Mathematics is up. Awesome stuff there, so go check it out. Something caught my attention. James Grime created a video of a math puzzle involving two trains and a fly. Hmm… sounds familiar… Then there’s the video with the solution: That sounds really familiar… Bzzz…
