Paysages Mathématiques<p>"It is important to point out that the mathematical formulation of the physicist’s often crude experience leads in an uncanny number of cases to an amazingly accurate description of a large class of phenomena.

Kinda like graph cellular automata but more the basic operations. I want to think about code AST transforms but would like to learn about general purpose graph transforms first. Boosts appreciated.</p>

Hi! This is my #introduction post here on absturztau.

I'm a lover of
#math (I have a video essay on the cardinalities of the naturals and the reals, as well as a complex function visualization tool), #computerscience (it's my major plus have a ton of side projects on my GitHub), and, of course, #gamedev (I was part of the gamedev student group in university and am currently developing a commercial game on my own).

I still have an active account on
mathstodon.xyz/@wqferr, but I was told I was really missing out on sharkey (and honestly my prev instance's emotes kinda suck).

These artworks are based on a generalization of Lucas sequences for complex numbers, defined as:
Z(0) = 1
Z(1) = 1 or i
Z(n) = shrink( e^(iθ)·Z(n-1) + Z(n-2) )

Where shrink() is a function which decreases a complex number into the two-unit square or the unit circle centered at the origin. In these works I use three different versions, based on taking out the integer part of the real and imaginary parts (or the integer part minus 1), or of the modulus of the number in polar form.

Figure 1 depicts the 128 values walk using θ = π/5 and Z(1) = i, and the shrinking function which takes out the integer part of the real and imaginary parts.

In the three artworks that follow, the lines connecting successive values toggle between being drawn or not. See the alt text for more information related to the artworks.

Dear mental calculators,
Here is a new hectoc challenge for you:

129843

The goal is to combine the 6 numbers to a total of 100. You can use the mathematical operations + - * / ^ and the parenthesis ( ). Numbers can be combined, but you have to use all 6 of them and are not allowed to change the order. See hectoc.seism0saurus.de for an example. Please use CW "solution".

Have fun! Your hourly hectoc bot

'The overall results, the most conclusive to date, suggest it’s time to shelve explanations based on biology or bias. Instead, it appears there’s something about early math instruction that produces gender disparities. '
