@Amikke it is a different situation from how most public bathrooms work now. there are norms in those situations. they are different in gender-neutral bathrooms, but not everyone has been in gender-neutral public bathrooms before. I'm not saying you have to set up a commission, but explicitly saying "guys, close the door to the stall even if you're just peeing" or "always raise the toilet seat before you pee" is something you should do, even if most guys would work that out on their own. not to mention, people police traditionally gendered spaces pretty severely -- that's not just the flip of a switch to change, but takes a process, even if it's a relatively short one.

as far as sexual misconduct, it still happens in "civilised society". as a relatively obscured space (i.e., closed doors, not visible to passers-by), bathrooms are places where sex-offenders are more likely to make their moves. women in particular are justified in not wanting to be in situations where they could encounter such people, like if they just need to pee, but it's in a place with less traffic -> more chance you're alone with a potential creep.

@mc I rarely use -u because I like the unset-is-empty behavior. you learn to think thru the what-ifs on that and add in the guards where you need em.. also test test test

@Amikke I think there should be separate spaces, generally. it's ok to be primarily gender neutral if you can set up that situation in your community and establish some norms, but, broadly, cis-gendered hetero people probably can't be trusted to act right in these situations

I made up a little demo to play with basic optics (Snell's law and internal reflection). I want to make a little game out of it, but I'm not sure where to take it from here.

@augustus it's weird how he's actually a real person and not a fictional character. life's funny sometimes

" the science performance of #JWST is better than expected. The optics are better aligned, the point spread function is sharper, and the optical performance is more time-stable. The fine guidance system points several times more accurately and precisely than required. The mirrors are cleaner..."

"better sensitivity ... by tens of percent... JWST will
go deeper faster than expected... enough propellant onboard to last at least 20 years."

"The report — Characterization of JWST Science Performance from Commissioning
— is now available; it summarizes the actual science performance of JWST as known on 12 July 2022, and how the actual performance differs from pre-launch expectations. The report quantitatively describes the performance of the spacecraft, telescope, science instruments, and ground system, as well as the overall observatory performance."

#JWST

@readsteven @thomasfuchs @tsturm

Big day for space science! From grand telescope views that #UnfoldTheUniverse, to extreme closeups of #SamplingMars, with rock cores barely the size of a pinky finger. I’ve now collected my 10th rock sample, seen here in the late afternoon Martian sun.

The best thing today was that we all lifted our gaze from ourselves to the universe for a moment.

JWST image 

So, what are we looking at in this image?

nasa.gov/sites/default/files/t

The image is stunning, a huge leap over Hubble (comparison at imgsli.com/MTE2Mjc3 ) and really showcases JWST.

The main target is a cluster of galaxies called SMACS 0723 (or more completely J0723.3-7327). Here's a preprint about the cluster: arxiv.org/abs/2207.05007

0723 is very far away, NASA says 4.6 billion light years. Astronomers measure these big distances as redshift, z. Our galaxy is z=0, 0743 is at z=1.38 to z=1.45

I think all of the spiky bois in the image are foreground stars (in our galaxy), so just a few hundred thousand light years at most.

The really interesting bit, and the reason for imaging 0723, is the stuff that's even farther away -- the gravitationally lensed galaxies, with their light smeared into crescents and whorls as it travels past 0723 towards us. We could see some of this with Hubble, but the added sensitivity with JWST is just spectacular. Those galaxies will be at z=6 and even deeper.
