For some reason the Nobel committee felt it necessary to issue a statement that their prize is not transferable: https://www.nobelpeaceprize.org/press/press-releases/the-nobel-prize-and-the-laureate-are-inseparable

Tarski's semantic theory of truth is often summarised concisely as 'The sentence "Snow is white" is true if snow is white.' Due to the quotation mark removal it is called the Disquotational Principle.

It is hated by teachers because it gives rise to the […]

@eliocamp That's pure aesthetics. Let's leave these details - such as which part of the whole data set should be visible - to the plotting routine 😅

@eliocamp Since the elephant curve coordinates are guaranteed to appear somewhere in the digits of Champernowne's constant, you could even fit an elephant with zero parameters!

[I almost said "in the digits of pi" but wasn't able to confirm Normality of pi in base 10.] […]

"With 4 parameters I can fit an elephant, and with 5 I can make him all fluffy." - John von Neumann

fluffy = 100
x(t) = -60*cos(t) + 30*sin(t) - 8*sin(2*t) + 10*sin(3*t) + sin(fluffy*t)
y(t) = 50*sin(t) […]

@fastness @emorydunn I'm mostly interested in how to get started to make my own, but also keen on seeing more art.

Also made a tiny tryptic on 1x2 inch chipboard panels. Getting the alignment right was annoying and I came close to breaking the nib on a pen.

As a connoisseur of minimalistic black and white generative art I'm really enjoying the #penplotter hashtag.

Can someone in that bubble recommend a good Getting-Started guide for someone looking to explore pen plotting a bit more?

Genuary 2026 - 11: "A Quine"

A quine is a program that outputs its own source code. Below is an attempt to write a quine as an R plot. Here is how it works: Write whatever it says in the image into a single-quoted string variable x (that is, x <- 'y=1:nchar […]

Genuary 2026 10 - "Polar coordinates"

You have probably always wondered what would happen if you kept transforming 2d points to polar coordinates forever. Well, you get an iterated map (x,y) -> (sqrt(x^2+y^2), atan2(y,x)). Shown below are the (smoothly […]

Many people have seen the equality 1+2+3+... = -1/12 and wonder how this can possibly make sense.

It makes sense in the same way as saying "there are square root of pi many ways to shuffle minus half a card" makes sense.

Both rely on taking a well defined […]

Finnish military dude discusses why US army have little chance fighting the rest of NATO in Greenland due to lack of winter gear. They're outmatched by at least a factor 10. Hardly a relief, but interesting analysis nonetheless.

@eve.gd This is a great idea! By hiding a hidden equal sign in the source code you can differentiate which candidates ran a simple piece of code in their head and which pasted it into chatbot. I'll have to remember that trick.

A big downside is the discrimination against visually impaired […]
