(1/4) Photos of X-rays. Top shows...
Top: a 47-year-old man without known comorbidities who received one Pfizer vaccine and developed COVID-19 2 weeks after. While he had a runny nose, mild body aches, and mild cough, his chest X ray is relatively normal.

Bottom: a 50-year-old active female patient developed lung damage (all the fluffy white bits that oxygen can no longer reach) and required the greatest amount of life support available, after contracting COVID-19 while unvaccinated.

"Vaccines are ~95% effective at preventing case 2 from happening. Of course there are also mild cases of COVID in unvaccinated Individuals," explained O’Shea.

I like that fact that this article reads as incredibly biased against the pub, but even with the slantiest ever slant, literally all they’ve got is, β€œyeah well the bar manager has some words in their Twitter name. It’s locked now but they did. Honest.”

edinburghnews.scotsman.com/news/politics/…
β€œOk I *did* shout at the manager, but they said a thing I didn’t like”

β€œThe stickers & leaflets in the toilets were Nothing To Do With Us.”

β€œWe kept our thoughts to ourselves. Except the ones on our t-shirts.”

β€œWe’re victims of a Very Unlikely series of coincidences, guv!”

One of my favourite science "facts" is that, by diameter, you can fit the other planets into the gap between the Earth and the Moon.

An argument recently broke out on Facebook about the truth of this, which led me to Check The Numbers.

Ready?
(1/6)
The Moon isn't always the same distance from the Earth. Its nearest point is called the perigee, furthest is the apogee.

The distance between the Earth and the Moon is 356,500 km at the perigee, and 406,700 km at the apogee.

The time-averaged distance is 385,000 km.
(2/6)
But.
Those distances are from centre to centre. So, we should subtract half the diameter of the Earth (6378 km) and half the diameter of the Moon (1738 km). That's 8116 km. So:

Perigee: 348,385 km
Apogee: 398,585 km
Time-averaged: 376,885 km

So, I've reached (atomic no.) 46, which is cool cos it's palladium, Pd - named after the asteroid Pallas, after Pallas, slain by the Greek goddess of wisdom, handicraft & warfare (there's a combo, eh?), Athena.

Shall we have a little palladium thread? Since you insist...
(1/16)
It's a great catalyst & is used in catalytic converters, in cars, which help convert unburned HCs, CO, and NOx-es into carbon dioxide, nitrogen and water. And yes, COβ‚‚ isn't great for the environment, BUT it's not so bad on the ground level. You win some, you lose some.

But it's spendy. More expensive than gold: it costs nearly Β£2k an ounce (~ Β£55/gram). It's dense, too (though the least dense of the Pt group metals) so that doesn't get you far. A cmΒ³ of the stuff weighs about 21.5 g & would cost you something like Β£1200.

It's #WorldCancerDay so, let's talk about some of the utter nonsense that's promoted as cancer cure #quackery. Spoiler: none of them cure any kind of cancer. They might give you other health conditions to deal with, though.
(thread: 1/8)
MMS (sodium chlorite solution) & CD (chlorine dioxide). MMS is sold as "water purification drops" & it does do that. It's also touted as a cure for literally everything, inc. cancer. It doesn't cure anything. It does cause gastrointestinal distress.

Homeopathy: substances so extremely diluted in water or ethanol that no traces of the original molecule remain. In quite a few cases, that's a good thing--because the stuff in question is pretty nasty. Anyway, at best it's just sugar.

β€œWe need you to teach key workers’ children.”

β€œOK.”

β€œAnd set work for, & follow up, all children who’re supposed to be working remotely.”

β€œRight...”

β€œAnd 3-5 hours remote learning.”

β€œWhat’re YOU doing during this?”

β€œGiven an extra Β£10k office costs to work from home. Why?”
β€œMm hm. And what about the children at home who don’t have laptops or internet access, whom you promised you’d help?”

β€œWe-ell. Money’s tight, you know...”

β€œTell me again about those PPE contracts?”

β€œThe Β£1.5 billion that went to Tory donors? What of them?”
β€œI mean,” *gets out calculator* β€œthat adds up to about... oh, about Β£170 per child in England & Wales.”

β€œSo?”

β€œSay a third need help, that’s over Β£500 per child. Easily enough to buy laptops andβ€”β€œ

β€œYes, yes. Anyway. Spot of lunch?”
