@rnanclares I’m not asking about light emitted by the sun specifically, and consider that (say) Jupiter doesn’t have a sharp surface either, but does have a reasonably well defined (though variable) reflectance from its outside.

What’s the surface spectral reflectance of the sun? I know it’s approximately a black body radiator, but clearly it doesn’t follow that it’s pure black. So what is it?

Today, we salute Thomé de Gamond, early Channel Tunnel proponent, who had to figure out the geology of the seabed first. https://m.gutenberg.org/files/66685/66685-h/66685-h.htm

etymologically, the opposite of “analemma” is “cathedral”

The #ParkFire event is, once again, re-writing the record books and "filling in the gaps" between recent extremely large wildfire footprints. This is California in the Pyrocene, and a couple of mild fire years (2022/3) don't alter that long-term trajectory. #CAwx #CAfire [2/2]

I feel like the one of the lowest level human internet problems we haven’t solved is how to be around millions of people, many of whom vocally disapprove of at least some of our thoughts and actions, without letting our hyper-social status-sensitive primate brains either melt or devote themselves to arguing that all our positions are the right positions for everyone.

Like yes, some algos are bad, but we also just built structures we can’t quite handle and are perma-mad at each other about it.

@kjhealy He’s more of a popularizer and apologist of modern conservative thought, though. To get it at its source, they turn to burkedecor.com/collections/sof

When I scheduled this live session yesterday to discuss Western North American wildfire situation, neither catastrophic fire in Canadian Rockies town of #Jasper nor dangerous #ParkFire in California had yet occurred. I will discuss both today @ 3pm PT. https://www.youtube.com/live/B5wskkRpadg

@kissane Erin! Hi. Uh, I just got an urgent message that you’re urgently needed offline again. Yeah, sorry, weird, right? It said it was urgent, though.

I am hilariously bad at going on vacation, but I was on the west coast and so I went to Cabo Pulmo, in Baja California Sur, to go scuba diving in the marine reserve. It’s kind of an incredible place — in 1995, the village (pop. 100 then, 150 now) worked together to get it declared a protected area. It’s now a UNESCO site and an absolutely thriving ecosystem, with careful ongoing oversight.

@thisisaaronland reading a lot of history books >> reading no history books > reading only one history book

@migurski Thank you, but we got through it with a big freezer bag. All set now.

A great way to save on those summer energy bills is to simply have your fridge break.

#PPOD: NASA's Curiosity rover ran over a rock and found crystals inside! They're pure sulfur. Elemental sulfur is something we’ve never seen before on Mars. We don't know much about these yellow crystals yet, but the team is already at work to figure it out! Credit: NASA/JPL-Caltech

An old friend is visiting, and we were walking through Berkeley. He pointed at an old restaurant and said “Hey! St Jude¹ took me to lunch at that Burmese place once! She was really nice.” and I felt very connected to a past that is not remembered well enough.

@brennen If I were doing this, and I’m not saying this is how a sensible person would, I would make an SVG and georeference it in QGIS.
