Like I have done once before, here are a few chosen links I have stumbled upon over the last few weeks. The only requirement for the links is that I found them interesting and they relate to math or science somewhat.

Emotional Perils ofMathematics –ย A short article on the life of a mathematician.ย On one hand, I think the author sounds a bit whiny, on the other hand I think he is right. When I first read it, I thought “uh, scary. I am glad I am only an engineer”. But reading it again, I don’t think this should scare anyone away from the field though, you should just be aware that most people probably feel that way once in a while, and you are no different. Unless of course you are the first grade mathematical genius.

A Nerdโs Way to Walk Up the Stairs – Tanya Khovanova has made a short blog post on how to walk up stairs, so you can estimate the number of step in the staircase…. I haven’t tried it…. but it works rather well in practice as well.

Ablaze – Can’t really tell you what it is all about, since I don’t really know. But it creates some visually stunning figures. The algorithm works by moving a set of particles through a path with some random component to it. If two particles are within a certain distance of each other a line is drawn between them. You can control the parameters for the algorithm. Useless but absolutely stunning.

Last but not least, I have found a population model that models a population size given a set of parameters, such as birth rate and mortality. It was spawned from the question whether you could find a formula for the number of shrimps you should have to have a stable population in an aquarium. I don’t think there is a closed form formula, but this model shows how difficult it is to get a stable population. It usually grows or declines.

Nothing hardcore math this week, but I hope you enjoy it anyway.

I’m definitely trying this on the stairs here at work.

Did it work? ๐

I think it did. But it probably needs training if you don’t want people to stare at you while you’re standing in the middle of the staircase thinking.

I couldn’t help laughing at that comment, keep it up and don’t let it hinder you. I know everything about making people stare ๐

I will. ๐
