How much does a solar eclipse dim daylight on Mars?

The animation shows 's capture of a solar eclipse by Phobos on March 25, 2019 (Sol 2358). Phobos is small and does not fully cover the disk of the sun, so dimming is noticeable but not comparable to that of a total eclipse on Earth.

This is your reminder that is constantly shilling billionaire ideology like Effective Altruism and is not to be fucking trusted.

Yes, they have cute birbs.

No, that does not exclude them from producing pro-billionaire propaganda that rots your brain.

@phryk@mastodon.social avatar

There's a reason their climate videos for example give completely undeserved weight to Direct Air Capture and other tech-based Carbon Capture "solutions" that are mythical at best.

There's a reason OpenPhilantropy, one of the biggest orgs pushing "Effective Altruism", keeps showering them with cash.

They're shilling out for billionaires.

So.. I think I've given up trying to find an opensource toolchain for setting up lathe operations in . I'm seeing this as an opportunity to learn more gcode and hand write some of the simple operations I want to perform. Here I am exploring arc interpolation G02 and G03 in lathe mode (XZ plane G18).

@chrishuck@fosstodon.org avatar

@concretedog You’re on the right track with the G2/G3 paths. The real trick is the roughing passes. There are lots of ways to do that. Mostly, I’ve seen it done as a bunch of stepped straight passes and then a final arc pass. I suppose there’s no reason it couldn’t be done as a bunch of arc passes? Lots of factors like insert geometry, tool rigidity, chip load, depth of cut, etc..

@mcdanlj@social.makerforums.info avatar

@concretedog I may have missed you saying something about this earlier, but have you looked at inkscape gcodetools? I think it has lathe support.

A lot of this short is in a new style of 3D — a more regularly shaded one than the cel-shaded 3D they usually use. It honestly goes pretty well with the 2D, and I think it'd be fun to see this style in a full video or two. Dunno if it should become a staple of Kurzgesagt's style, but it's def interesting.

I'm gonna ask a question. It's just something I'm curious about and intrigued to see the reasons. Privacy is, after all, up to each individual...

If you don't have a photo of you on your profile... why?

Those shapes look so 'organic'. I wonder what chemical process (other than slime molds) causes the sediment to clump like that?

@65dBnoise@mastodon.social avatar

Although IANAG, erosion seems to be the cause for many of those strange structures, both in large and small scale. On Earth too. Soft material goes first, harder material is left intact for a longer time. Here it all happens in a much weaker gravity, and a much thinner atmosphere.

Call your students co-learners, and tell them that you are learning to teach while they are learning the subject matter with each other. Students take statements from teachers as authoritative. In my experience, learners take to the nomenclature and the notion.

I scaffolded this with a specific statement about how this differs from traditional learning.

You could say, I started reading in 2023.

I didn't read your book. I don't read books.
It has to do with focus and I didn't even read "required reading" in school. I did well at the paragraph level, never beyond a page.

Some of these books were condensed PODCAST or presentations of a series, like Psychology, Philosophy, Astrophysics, etc. Some were novels.

The most I have read in my entire life, in 2023. Three earbuds, three BT Headphones later

@tc_morekindness@c.im avatar

@Rasta Wow. Impressive. Which 3 or 5 were your favorites?

@Rasta@mstdn.ca avatar

Took a break from history to hear a few more

Margaret Atwood - Handmaidens Tale
I never watched it on the TV series, but knew of it, so I listed to the Audiobook all at once.

Robert Louis Stevenson - The Strange Case of Dr. Jekyll and Mr. Hyde
(Missed Childhood)

Agatha Christi - Black Coffee
(Famous author, should know something of them)

Charles Bukowski - Post Office (and others)

What is #Curiosity?
We have 12 open PhD positions, and 2 PostDoc positions to investigate the neural basis and the cognitive concepts of curiosity, starting summer 2024.
Join us in Göttingen!

The Priesemann Lab ( @ViolaPriesemann) is looking for PhD candidates (12 free positions) and PostDocs (2) in a very interesting project investigating the neural basis and cognitive properties of . Start: summer 2024 in

#Curiosity is currently pulling a big wheelie on #Mars, and the drive on Sol 4041 to get a wheel back on solid ground faulted out after moving only a short distance. MARDI is helping turn lemons into lemonade, as the limited motion provided just enough offset for a stereo image. Here's a red-blue anaglyph of the ground under the rover processed from the publicly available raw imaging.
