Pinned, entropy augmented, digitally normal distribution, of no particular work-related use and thus perfectly suitable for today. Code in R: iters = 1000 sd = 2 precision = 20 results = rep(0,it...

A couple days ago I noticed a fun piece of R code by Allan Roberts, which lets you create a digital snowflake by cutting out virtual triangles. Go give it a try. Roberts inspired me to create a w...

Fantastic map which shows the location of every death on US roads from 2001 to 2009. Go take a look then come back and tell me…. What location did you zoom in on first, and why?

Imagine a unit square. Every side has length 1, perfectly square. Now imagine this square was really a fence, and you picked two spots at random along the fence, with uniform probability over the...

Last night, while playing Boggle, we ended up with a board without a single vowel. Not even a “Y” or “Qu”. This seemed fairly unusual, so I wondered what the chances were of such an occur...

What if you wanted to randomly place objects into a field, and the more objects you had, the more they rejected newcomers placed nearby? To find out, I setup a simulation. The code, shown at the ...

Coded as follows: x = seq(.001,50,.001) par(bg="black") par(mar=c(0,0,0,0)) plot(x,sin(1/x)*rpois(length(x),x),pch=20,col="blue")

$100 to the first person who can figure out how I created this plot and replicate it. Some hints: It was done in R. There is only one underlying probability distribution involved (one “rdist()...
