You can see a bundle of nerve tissue travelling back toward the brain, carrying signals from the eye. Gastropods have wildly varying eye anatomy, from simple light receptors to complex camera eyes.
you’d think they would have been able to get more than 50 undergraduates to do. it doesn’t take a long time and requires answering no surveys
Also, psych researchers have a reputation for lying their asses off to the subjects regarding [what a study is actually about] until after it’s over. I would seriously consider pressing the button once or twice just to see if they were telling the truth about it being a shock button.
(Not sure if I’d *do* it, but I’d seriously consider it, and I would definitely wonder if it was some sort of covert test that I was failing by not pressing it.)

so tonight I’m at synagogue, listening to the Purim Night reading of the Book of Esther, like you do
and near the end of this chapter my brain presents me with the following:
nooooo ooooone plots like Haman calls the shots like Haman plans a genocide by casting lots like Haman
(It only works with the Hebrew pronunciation of Haman, which, like Gaston, is accented on the second syllable.)
By the time we get home my brain has added:
for there’s none so well-favored and kingly yes, we all can be certain of that he’s so rich that his pockets are jingly and he looks really sharp in a three-cornered hat
*face in hands*
Petition to sing this every year at Purim.
I shared this with my dad, and he added:
No one’s spruce as Haman, Nor abstruse as Haman; No one’s half as good tying a noose as Haman! He’ll use gallows in all of his decorating! No one else hangs as well as Haman!
niiiiice
@maryellencarter, here it is, and thanks for the reminder to reblog it this year.

Winter is always this horrific balance. On one hand, it’s too cold to wash a car. You’d have to be stupid to be out there in -20°C, running out of your house with a bucket of boiling water, trying to get to your panels before it instantly freezes solid just from touching the outside air. On the other hand, the city keeps putting road salt down like they own a dividend stake in the abstract concept of salt. You need to wash, and yet you can’t.
Now, I also know what you amateur scientists are going to say. “It can’t rust, it’s too cold for the endothermic reaction of iron oxidation to occur, you’re fine to wait to wash the car when it warms up.” Then it’ll be rusting! Do you also wait for your enemies to wake up before you stab them to death? Don’t answer that. Also, I’m pretty sure I read somewhere that Mars is red because it’s made of rust, and it’s hard to get a lot colder than there, too.
Most “car people” just shrug their shoulders at this problem and buy a cheap winter beater. This vehicle is sacrificial, they say. It does not bother me that it is corroding away before my very eyes, because doing so prevents my nice Lexus from developing spots of rust as well. These people also must have a “parts kid,” just in case something happens to their firstborn, because every car is special and unique and deserves to be preserved. Plus, if they keep buying up and destroying all the $1000 rust buckets, then what am I going to drive?
Last week, I awoke one morning from uneasy dreams to find myself in possession of the answer. I would simply add a sacrificial coating to my vehicle, encasing it in an inch of bulletproof and saltproof epoxy. So far, this method has worked really well. The salt just slides right off it, and onto the car behind me. There’s just one downside: since the doors no longer open, I have to keep the window rolled down all the time so I can get in and out. You might think this is “cool,” like the Dukes of Hazzard, but Bo and Luke never had to deal with trying to get a pregnant raccoon out from the back seat of their Volare.

#anything that makes me laugh this much deserves a reblog #unreality cw #this probably deserves some other warning tag but I am not sure what
it was a fucking house phone that i was so stoked to have because it was mine that i kept in my own room and i cannot believe technology has progressed at the speed of FUCKING light to the point where this is a hilarious artifact to have had in like 6th grade and now theres kindergarteners with iphones
each button made a different tone so the numbers you dialed a lot became a subconscious melody in your head and if you hit the wrong button by accident it would sound like a wrong note in a song you know by heart
Do you notice how the question says “how did you know if you dialed the right number” *full stop*, but the *answer* is specific to “numbers you dialed a lot”?
Yeah, dialing numbers you *didn’t* dial a lot–which was just about all of them if you were a kid! it’s not like kids have much reason to talk on house phones, not being in charge of coordinating any appointments and not having had much time to accumulate friends-no-longer-in-physical-proximity!–was *exactly* as anxiety-ridden as it sounds. It’s such a relief to have screens to double-check with. Even *dumbphones* like the phone at work have screens now.
(Plus phones with screens *also* make the button tones, as a second layer of defence. Do y’all not have the button tones on your smartphones? Did you turn them off?)
I’m not sure if the button sounds on my phone defaulted to off or if I turned them off by choice, but I have never felt any need to turn them on. This probably relates to the fact that I can’t remember a melody without words and that phone numbers do not adhere to the melodic principles of Boethius anyway (okay, I never actually made any sense of Boethius, but he was the “Great Book” cited on Why Music We Don’t Like Is Objectively Bad and as a side note Stop Liking Pentatonic As A Scale It’s Unchristian) uhhh where was I. Right. I can’t remember numbers anyway, I can’t remember the little tune associated with the numbers, so they just all sound wrong. It occurs to me though, and the deficiencies of my auditory memory may be assessed by the fact that I’m not actually sure, but in the part of my day job that involves helping set up brand new phones and then telling the person “now please dial our test call number which is such and such”, I don’t think I usually hear dialing beeps before the announcement. Maybe new smartphones come with the dialpad beeps off by default.
There is a distinct possibility that smartphone button tones are opt-in, and my family is just in the habit of switching them on. As it happens, my first-ever SIM card† is currently in the mail, so I guess it will soon be time for me to investigate a phone app’s settings myself.

@sigmaleph [link], there’s still the part where you’re waiting for them to pick up! And it’s been my experience that often *somebody else* will pick up the phone, and then you have to sort out whether this person is sharing a phone line with the intended person or whether they’re completely unrelated.

1. Since coronaviruses, being dependent on an envelope, are generally one of the easier viruses to destroy, my baseline initial assumption was that standard disinfectants work. I know there *are* some bottles of ammonium-chloride-based disinfectant sprays at the grocery store now advertising themselves as “approved for use against COVID-19”, though I haven’t looked into the details of such approvals myself.
(Also, if you replace store-bought quat wipes with homemade quat wipes, any change in effectiveness will not be because of problems common to all quat-based cleaners.)
2. I gather that SARS-CoV-2 fomites aren’t a big deal, except maybe under extreme circumstances like caring for COVID patients: it’s the airborne stuff you gotta worry about.
This is mostly a general zeitgeist thing and I don’t have many links on hand, but off the top of my head there’s the argument-from-salad-bars [link].
The main reason to disinfect stuff is to prevent COVID *scares*. All else equal, catching a cold during a pandemic is worse than catching a cold under normal circumstances, because now you have to worry about whether it’s actually the plague. Plus if you catch a *really* bad flu and end up hospitalised, that’s one step closer to overwhelming the hospital (and god help you if they’re *already* overwhelmed).
—
I personally haven’t been disinfecting my respirator (I wash my hands after touching it if it’s been out in the last 3 – 4 days; if possible, I also wash *before* touching it), but OTOH I have 15+ years’ experience with tracking potential-fomite statuses in my head and exercising caution in what I touch accordingly. For people who haven’t trained on that until it becomes second nature (perhaps because they didn’t have the threat of horrific colds to motivate them [link]), disinfection often makes sense.
(Plus ULine was out of stock when I bought my filters, so I have the pink-circle ones. There’s only so much disinfection I’d be able to do.)
I *do* disinfect my smartphone after every outing, but I was already in the habit of doing that before COVID-19. (Note that I have a screen protector and a case, though you *might* still be able to get away with it without those.)
—
P.S. Since apparently we’re talking about quaternary ammonium in more than just an aside now, while we’re at it: *don’t* use ordinary cotton for your homemade disinfectant wipes! [a source]
P.P.S. Oh, also, I just noticed the term “handwash” in your ask. That might have something to do with it, since you’re not supposed to use quaternary ammonium as hand sanitiser: it’s a mild skin irritant. (To be completely honest I occasionally end up doing it anyway at work, but that is part of why I use shitloads of moisturiser.)
