That’s an EPS-12V 8-pin power connector (usually goes to the motherboard). The GPU wants more power than a single PCIe 8 pin will deliver on its own and it may have come with a splitter that takes the EPS connection and converts it to 2 PCIe 8-pin connections. support.exxactcorp.com/hc/en-us/art...

8. Speaking of white balance (or more accurately: color constancy), you can trick this system with various illusions like these butterflies. They’re the same color, they only look different because they’re on different color backgrounds.

5. Ultra fast eye tracking and something called Adaptive Optics has made it possible to take high resolution pictures of the retina in a person’s eye, and label (false color) the red, green and blue cones. These pictures are amazing and I want one of my retina really badly… #soon

Friday morning timeline cleanse: Seattle sunset at Green Lake from earlier this week.

Some of my favorite signs from yesterday’s #standupforscience rally in Seattle. Incredibly heartening to see the whole scientific community come together like this 🥲

#standupforscience Seattle!

I have a lot going on right now (lots good, some bad) and I find myself feeling super grateful for the refuge of art. My partner got me back into pottery last year, and it’s played a huge role keeping me sane and happy. Being a scientist is amazing, science+art is greater than the sum of its parts.

Welp, TIL Bluesky doesn’t support GIFs when uploaded directly from your phone. Here’s a screen recording of the animated version:

What’s one way you show people your research is actually super duper cool actually?

Innocent bystander: what do you study?

Me: I’m looking at potential retinal contributions to color constancy… *sees eyes glazing over* … uhhh … look these butterflies are the same color, they don’t actually change!

This is the difference between full Deuteranopia (dichromacy), and a severe Deuteranomaly (anomalous trichromacy) where you have blue cones and two variants of the red cone that are only VERY slightly different from one another:

This can make a BIG difference in what you see. We created a simulation in the lab a couple of years ago to show this difference. So if we take this balloon image:

When someone says they’re color blind, they probably mean they failed a color vision test that looks like this one (called the HRR) at school or their local optometrist’s office.

Haha I feel like “XKCD did it” is the sci-com equivalent of “Simpsons did it” at this point. There’s always a relevant XKCD comic.

I still think of this one any time someone mentions computer vision
