Now looking for volunteers for a color vision study.
We are particularly interested in individuals with color vision deficiency, however all vision types are welcome, ages 20 and up.
If you are interested, or you know someone that could be, please email: [email protected]
Optionally, include answers to this prescreen:

When David Smith, Joseph Myers (@jsm28), Chaim Goodman-Strauss and I posted our paper "An aperiodic monotile" (https://arxiv.org/abs/2303.10798) back in March, we answered the open problem of whether a single shape could tile the plane aperiodically.
Some people observed that tilings by the "hat" used both unreflected and reflected tiles. Although the einstein problem was answered, in some contexts (e.g., tile floors), you'd likely have to manufacture two separate tiles. Our paper left open the question of whether a shape could tile aperiodically using translations and rotations only, with no reflections.
I hate to sound like a broken record, but then, on March 26th, Dave noticed something interesting. (1/n)
A longstanding open problem asks for an aperiodic monotile, also known as an "einstein": a shape that admits tilings of the plane, but never periodic tilings. We answer this problem for topological disk tiles by exhibiting a continuum of combinatorially equivalent aperiodic polygons. We first show that a representative example, the "hat" polykite, can form clusters called "metatiles", for which substitution rules can be defined. Because the metatiles admit tilings of the plane, so too does the hat. We then prove that generic members of our continuum of polygons are aperiodic, through a new kind of geometric incommensurability argument. Separately, we give a combinatorial, computer-assisted proof that the hat must form hierarchical -- and hence aperiodic -- tilings.
There is only one correct response when an organization like @gutenberg_org joins the fediverse (Mastodon in this case):
"Welcome!"
I'm having a hard time dealing with all the bullshit accessibility.
Going down the ableist road to get a couple of views on social media is not the way.
So yeahy accessiblility trendy. Which means a lot of false information and potentially harmful one is spreading.
I'm trying to follow my usual "promote what you love". But at some point, I'm starting to find it hard not to point out all the bullshit. Expect if I do that it will bring it visibility. Loose/loose...
“85 percent of the world’s population has experienced a decrease in freedom of expression in the last five years”
Do you ever get the feeling that you should just take a year out of your busy life and really delve into Maxwell's equations and truly come to a deep and intuitive mathematical understanding of magnetism and electricity? Yeah, me too. It's a feeling we all share.
DysTitles so shockingly bad I can only assume that severe cognitive dissonance is somehow behind it, as in maybe those weren't truffles for lunch, but "special truffles"....
Or something.
Here's what the real actual research says:
1) Dyslexia is a language issue not a visual issue.
2) Dyslexics need good contrast an appropriate white space, not junk pseudoscience crazy fonts.
3) The comparison images are examples of bad design.

IMO, DysTitles is beyond ridiculous.
When people come to visit from out of town, they invariably say “we want to go see the tar pits!“
My respons is “um, why? Here’s a spoiler: it’s a big smelly pit of tar”
Them: “but the dinosaur bones…”
Me, cutting them off: “..are not there”
Wait wut?
The dinosaur bones are at the Natural History Museum, in exposition Park. La Brea tar pit just has a better publicist …
