Medical device R&D day job, STEM+Art education volunteer nights and weekends. Big emphasis on introducing discrete mathematics to K-12 with hands on mathematical art projects.
Like this - Moving to 2" unit cubes for pentomino project. I talk with Minneapolis North HS next week about a collaborative project in art, discrete mathematics and computer science. If all goes well we will publish with Journal of Humanistic Mathematics.

Still haven't got an eyepiece filter but I am figuring out how to take a cellphone pic without an eyepiece mount.

"two old dudes smoking weed" image is too hard to find so - this weird pic. Ad for gummies (I guess) that I didn't click on.

I did try to "vibe code" this with Gemini in Colab-complete incomprehensible mess. YouTube videos were much more helpful. Reading and running example code that used the fundamentals key also.

# with open('data.txt', 'r') as file:
# data = file.read().rstrip()
with open("/content/SampleSolution1.txt","r") as lines:
lines=lines.read().rstrip()
#print(lines)
lines = lines.replace("4","Y").replace("10","N").replace("11","W").replace("12","X").replace("8","U").replace("7","P").replace("9","T").replace("1","Z").replace("2","V").replace("3","F").replace("5","L").replace("6","I").replace(",","").replace("\n", "").replace("\r", "")

Lots more to consider, like just stop using Meta but why leave if I can stay and grind its gears.

This is a light guide fixture I made for testing pulse oximeters. Has a little bit of a flux capacitor vibe.

Perhaps a little off topic but this is my latest "how does YouTube not notice these stupid scam ads." This one isn't as demonstrably porny.

Oops! I always think I have this thought out before I post. Thanks.
I think this is it. F branches to T and X with single square moves. X and T both have two square moves to W. X moves are symmetrical though.

Seems like a reasonable math art abstraction to play with in air dry clay and acrylic paints.
also - I think the pentominoes I sketched in a spreadsheet are the "minimum moves of squares" pentominoes. If you start with "I" anyway.

Hey all my Blue Sky math and more pals. I would not have done this silly bit of pentomino python without your pleasant correspondence on mathematics, programming and being nice person.
I tweaked somebody's(link in replies) pentomino solver to work from unique X piece placements.

It's my birthday season! I made Labor Day - Thanksgiving a special celebratory season for autumn bday folks like me.
Helps with scheduling to have ~90 days available for special dinner/drinks/coffee dates.

I have a similar vibe for the Soma Cube. I love finding the beautiful structure hiding in them.
