Thanks again for this, Ryan. This is a delightful resource and I'll be keeping an eye out for these birds in my travels.

Far be it from me to impugn the data quality of whoever was scanning finches, but I just don't believe this finch, the "dusky munia" reflects 33% of it's incident light and 75% at peak wavelengths.

Common confusion. Mutual AID stands for "Mutual AI Development" in which you take the time to visit and enjoy the vibe coded websites your mutuals make. In that sense, a datacenter is already a mutual aid center, so the conversion is easy.

I need a concept like convex hull, but that isn't convex. I'm trying to characterize the birds with the most extreme colors. Here I've taken 5 degree angular samples around white, and picked the furthest point within them, but you can see the big gap in the reds.

's color post, you can get a wee taste of expanded color gamuts if you have a modern (e.g., Apple) display with wide-gamut.com/test Just the difference between sRGB and P3 is pretty striking

This is one way that wilderness in the Eastern US mogs the west. We have lots of things out here, craggy mountains, giant trees, canyons, wide open spaces, but we don't have any greens like this.

What are the natural units of a spectrum that make typical physical spectra into a mixture of gaussians? If I'm using linear wavelength units, should reflectance spectra be made of log-normals or normals?

I'm learning that in the laser pointer market, if a product is intended enough for enthusiasts that it specifies its wavelength, it also has enough power to burn things. Low power lasers with a number in nanometers in their specs are very hard to find.

A practical application of the sleeping beauty paradox. If you've been sleeping poorly recently (jetlagged/sick/too much coffee) if you feel yourself waking up you're better off assuming it isn't morning yet and trying to go back to sleep without checking your phone.

It's strange that we accept this sort of restriction on our freedom for drugs or interventions that don't have externalities. Antibiotics, sure, we have a limited microbe evolution budget. Insurance wants a doctor sign off before they pay, makes sense. But if you're paying yourself?

The writing here is sublime. Excellent science writing for the masses carries you along from new concept to new concept, and you never feel lost. At the same time, when you're done you are aware that you learned and also that you know almost nothing! Great stuff, take the time to read it

I didn't include it in the post because it wasn't directly related but I also ranked birds by their variety of color (mean squared chromaticities distance of samples from their mean.) Pictured are the top 4.

Truly amazing I've read and thought about several explanations of what we used to call gamuts in printing. But this is by far the best I have read. Very easy to understand. One of my previous favorite examples of s color that exists but we can't reproduce in print or on screen is the campfire.

In the vote by mail debates a lot of people complain about vote security, but no one mentions how much it improves vote quality. My votes are way more thorough and informed because I can vote at my dining room table. I vote more often, and I vote better, as a direct consequence.

How much of the memetic success of Christianity and Islam over prior pagan religions was a matter of replacing falsifiable boons, peace, plenty, victory, with unfalsifiable ones, paradise in the afterlife? Easy ratchet to replace a god which can visibly fail with one who can't.
