Today I Learned

Today I learned that cleaning a white hat can be done with bleach cleaner, but it’s important to rinse it before wearing it again. I also discovered that "oyster veneering," a woodworking technique from the late 1600s, is experiencing a minor revival despite its labor-intensive nature. Additionally, I learned that the factorial of 23 (23!) equals 25,852,016,738,884,976,640,000, which interestingly has 23 digits, a unique coincidence among factorials. I found out that medical specialists often spend less than 10 minutes with patients, and that watching TV can contribute to weight gain. Other insights included the fact that a kiss can transfer around 80 million microbes, and that bureaucracy can sometimes hinder employment opportunities. The discussion also touched on various trivia, such as the emotional sensitivity of barn owls and the complexities of gravitational lensing around black holes.

I disagree. Septic tanks have some utility.

I think terms for shepherds is a bit harsh
Nothing for physicists or Chemists
Mathematicians is a bit predictable , they could have been more inventive than “set” I think.

"A smear of gynaecologists"... :oldruck:It could be worse: "A bestiality of shepherds"?
[Reference: ancient Dave Allen joke about a ventriloquist.]
Yeah the Gynaecologists seems rather unpleasant, mind you considering the area of expertise I suppose options for something less distasteful are limited.

One could have fun with this
A quantum (I also like entanglement) of physicists
A mole of chemists
An infinity of mathematicians – I would like @fresh_42 view on that
A byte of technologists
A megabyte of programmers
A plasma of particle physicists
A cluster of cosmologists
A manifold of geometers
Engineers?
From experience a Beer of Engineers would be a fit and it also has a ring to it.

Today I learned that the Mission: Impossible theme is in 5/4 time, so the first two notes are a beat and a half long and the second two are a beat long and it kind of sounds like 4/4 with a speed change every second beat.

Apparently the inspiration for the rhythm was that two long beats and two short beats (dah dah dit dit) is Morse for MI.

Hmm. A "Brewery of Engineers" is probably closer to the correct scale.

Or maybe a "Chunder of Engineers"?

Today I learned you can use vinegar in place of fabric softener. I tried it and surprisingly it works. It's the first time my towels have been soft since living in my current place which has no drier.

Vinegar also helps remove the laundry detergent residue and perfume that never seems to be completely rinsed out.

(speculation: That might even be why it softens the fabric.)

Today I learned that you can adjust the step speeds of stepper motors (such as those found in old floppy drives) to make different pitches of buzz. You can probably see where this is going:

Today I learned how to open a tin can without a can opener (the ring pull snapped off in my hand). All you need is a teaspoon.

This man was stung seven times by murder hornets while trying to save Vancouver Island's honeybees

6th Asian giant hornet to be discovered in B.C. found in Fraser Valley
https://www.cbc.ca/news/canada/brit...vered-in-b-c-found-in-fraser-valley-1.5797706

Destroyed 'murder hornet' nest near U.S.-B.C. border contained nearly 200 queens, scientists say
https://www.cbc.ca/news/canada/brit...ornet-nest-washington-bc-200-queens-1.5798631

I know that one or two have been found in Washington State. "In December 2019, WSDA received and verified two reports of Asian giant hornet near Blaine (Whatcom County). These are the first-ever sighting in the United States. Canada had also discovered Asian giant hornet in two locations in British Columbia in the fall of 2019.

In 2020, both Washington and Canada have had new confirmed sightings of Asian giant hornet and in October of 2020, WSDA conducted the first-ever eradication of an Asian giant hornet nest in the United States."

It is claimed that trees did not evolve wood so that they could better access sunlight (than shorter plants).

I am terrified of bees and wasps, I am not sure I have ever seen a hornet. My worst night mare being attacked by them.

Is there a thing with cicadas and primes?
I read on one of Dawkins' books, I think, that long period cicadas tended to have prime periods because things that ate them couldn't emerge on factors of their period and eat something else - e.g. this ten year cicada could be predated by the five-year-cicada-eating-beast that emerges every five years. But a thirteen year cicada can only be eaten (except opportunistically) by a thirteen year cycle creature.

Misleading popsci, maybe.
