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.

It's usually attributed to Churchill, but he himself wrote "it is said that ..." before that quote.

I just thought to have read once a similar one "Democracy is awful but it's the best we've got" and I think they referred to Popper. But I might be wrong.

TIL who is Nigel Farage
Jonathan Scott said:
although I'm inclined to blame politicians in general for the result, encouraging self-interest not in a "win-win" way but at the expense of everyone else, and wildly distorting facts as if there were no possible consequences.

Didn't your C Northcote Parkinson predict that's what bureaucracy will do ? And that by around 2030 100% of Britons would be working for their civil service?
We're certainly headed that way here in US as politicians try to base the economy on paying one anothers medical bills and welfare benefits.

Good Luck to you guys
FWLIW i think you did the right thing.

TIL that for about 300 years, the Immovable Ladder has sat in the same place at the Church of the Holy Sepulchre "due to an understanding that no cleric of the six ecumenical Christian orders may move, rearrange, or alter any property without the consent of the other five orders". :oldeyes:

Nitpick warning...
Do you really mean she knows physics rules better than she knows you? If not, ending with "than I do" would probably convey your meaning more successfully.

I'd heard the name Fermilab before, but just seconds ago learned it is the University of Chicago/DOE's particle accelerator. I'm just pleased with myself that I was able to recognize a particle accelerator from 28,000 feet!

TIL that the "Oregon Chub" is the first and only fish on the endangered fish species list, to be delisted.
Scientific Name: Oregonichthys crameri

Status: Delisted due to recovery

Recent Activity: On February 18, 2015, the USFWS announced the removal of the Oregon chub, and its critical habitat, from the list of Endangered and Threatened Species, and the Oregon chub became the first fish ever to be delisted due to recovery.
[ref: U.S. Fish & Wildlife Service, Oregon Fish and Wildlife Office]

I learned this whilst researching a solution to the mosquito problem that the pre-fair crew is describing at the location of the OCF. The fair starts in 10 days. Tickets are not available at the gate. You must buy them in advance.

ps. I also learned today, that not all hippies are fond of patchouli oil; "Life hack: pouring gasoline on yourself and lighting a match usually keeps mosquitos away. And it smells better than patchouli"

I still don't know what patchouli smells like.

Similar to the smoke of weed. A little bit sweeter.

Huge Helium Gas Field Found in Africa Is a ‘Game Changer’

TIL" the discovery of a huge helium gas field in East Africa is a “game changer for the future security of society’s helium needs” amid a global shortage."

There must be a lot of heavy elements in the region.

I wonder if it were related to the east african rift system, its movements resp.
Edit: I suspect the shortage will be back again as soon as the chinese collider will be cooled down.

But then the news makes me wonder how diet sugar is functionally different from that special sugar they produce. Uhm, maybe a new variant of the same kind but will increasing or changing the physical shape of glucose induce more coming production of CO2 in our blood ? What does our body do with those glucoses that can't be absorbed ? What about statistical data obtained in measuring how this approach is more helpful to patients of diabetes ? etc.
I guess it's all just about "Eat less sugar" then, which is the point of diet sugar sold in most supermarkets.

Oklo is in Gabon, which is on the west coast in Central Africa. Gabon is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. The helium discovery is in Tanzania, which is across the continent on the east coast of Africa. Tanzania is bordered by Kenya and Uganda to the north; Rwanda, Burundi, and the Democratic Republic of the Congo to the west; Zambia, Malawi, and Mozambique to the south; and by the Indian Ocean to the east.

i have tried to read about metabolism of sugar but the chemical names are ever sooo loooong and I'm bad with names anyway...i get lost.
Not everybody metabolizes sugar the same though.

i've been experimenting with my own blood glucose

cut out sugar almost entirely
bought one of those meters and log morning readings on the fridge.
here's April, i haven't scanned May or June yet
i noted what i ate late in the day.

glucoseApril 2016.jpg
In me, starchy food turns overnight into glucose as evidenced by my experiments eating them with or after dinner , shown above
so now I'm eating cauliflower instead of potatoes and pasta .

dropped about six pounds in April
and by late May no longer waking up at night with numb feet

i'm at the age i have to watch what i eat
i have known for years that sugar causes in me craving for more of it
so probably i am diabetes prone.

finally losing the craving to snack in the evenings
and morning BG readings are trending down 108 yesterday .

Slow steady progress i hope, or at least halt the decline.

Please at the soonest possible time tell this to your doctor and show him that chart.

Sounds like an interesting experiment.
I self-diagnosed as "hypoglycemic" about 30 years ago, based on what a doctor on TV said, regarding symptoms, and the cure.
Fixed me right up.
Someone about 10 years ago described the same symptoms, so I told him the story, and the cure.
He told me the next day, that I'd cured him.
Yay!

Ours apparently wasn't a dietary sugar problem, but a dietary protein problem.
cut out sugar almost entirely
I've been slowly cutting down on my salt for the last 15 years.
At one point, I was consuming so little salt in my regular diet, that I had constant cravings for "Cheetos".
I thought that was kind of ironic.
bought one of those meters and log morning readings on the fridge.
That sounds like fun.
Just finished googling the expense of the equipment required.
I would suggest that we should start a new thread, and publish our findings, but I think we'd get in trouble for that. :redface:

meter is $9 at Walmart, Walgreens is comparable
about $15 more for test strips and a spring finger-pokey lance that's well worth it for it's almost painless...

TIL that Lockheed began working on a jet fighter as early as 1939 - Lockheed L133. Nathan "Nate" Price was the principal architect under Clarence "Kelly" Johnson of P-38 and SR-71 fame.

https://en.wikipedia.org/wiki/Lockheed_L-133
https://en.wikipedia.org/wiki/Lockheed_J37

The video shows a German jet with a twin tail that flew first in September 1939. It looks like a Heinkel, or perhaps a Messerschmitt, but it looks like a design of the former.

Today (well, yesterday now) I learned what it's like to play a Broadwood piano from 1846, specifically this one, which is in "The Vyne", an old house near Basingstoke:
https://www.facebook.com/VyneNT/pho...4846597643271/858011557660101/?type=3&theater
Visitors to the house are allowed, or even encouraged, to play it. It has a very light and shallow touch (much lighter than any modern piano), but could play very fast (a feature of the "patent repetitive action"). It was a bit clangy and in need of tuning, but now I feel I have a much better understanding of the sort of piano that Chopin and Mendelssohn would have played.
