@shawnpeters1982.bsky.socialMathober Day 12 - Reciprocal Prime Constant
The reciprocal prime constant, or Merten's constant, is the sum of the reciprocal primes minus ln(ln(n)), as n approaches infinity. Merten's constant has an approximate value of 0.2614972128.

@steckl.esI continue to find a bit of time each day to produce a zine for #mathober! Today's is about the Reciprocal Prime Constant, which is nicely related to a thing I already knew about, but M is new to me. PDF: https://katiesteckles.co.uk/mo12
@fractalkitty.comI found a big sulfur shelf at the park yesterday to doodle today's #mathober - Problem of Points

@johngolden.bsky.socialAt the end of #mathober I usually draw calaveras for our beloved dead. Is there someone from our community who passed this year that you want remembered?
@shawnpeters1982.bsky.socialMathober 11 - Problem of Points
The Problem of Points is an exercise in fairness and probability. If two people agree to play a number of rounds to win a pot of money, and the game is interrupted, how can you best distribute the pot?
@steckl.esIt's the 11th of #mathober and today I have made a little zine about the Problem of Points, which I'd never heard of but has quite a cool story! (PDF to follow later when I'm near a scanner.)

@steckl.esToday's #mathober prompt is Simple Pole, and I've done a little maths zine explaining what one is. (PDF to follow when I get near a scanner).
@daniel.colquitt.xyzAt these concentrations, nitrate isn’t a particular concern. I’m more interested in establishing how much accumulates between water changes, particularly as the new plants become established.
Next measurement in a week.
@daniel.colquitt.xyzWith 10 panda corydoras, 7 platies, 2 honey gourami and an increasing number of plants, I’m interested in the balance between feeding, nitrate production and plant uptake.
@daniel.colquitt.xyz@daniel.colquitt.xyzThe previous measurements had pushed the estimates upwards. Today’s results have pulled them back down.
From a #fishkeeping perspective, the lower readings are encouraging.

@shawnpeters1982.bsky.socialMathober Day 10 - Simple Pole
Starting with a Mondrian-inspired pattern of coloured rectangles, this sketch illustrates a simple pole using the function f(z) = frameCount/z, distorting the original image over time.
@fractalkitty.comToday's #mathober - k-cyclic graph. I did polygons (1-cycles for my code and desmos) and a few with mycena fungi in the doodle.

@shawnpeters1982.bsky.socialMathober Day 9 - K-Cyclic Graph
A K-Cyclic graph has a closed walk of length k. In a fish graph, the graph can be cycled in 7 steps.
Using wobbly sine functions as a background, fish graphs swim through the sketch.

@steckl.esAnd I've found time to do a quick zine for today's #mathober prompt, k-Cyclic Graphs. Here's a photo, and I'll add a link to the PDF when I'm near a scanner. Graphs!
@steckl.esYesterday's #mathober prompt, PARABOLIC ROTATION, led me to a fun yet mysterious function! (No scan just yet as I'm on the road, but will add links later)
