SUMMARY

This discussion revolves around the concept of daily learning, where participants share various facts and insights they have recently discovered. Key topics include the woodworking technique "oyster veneering," the mathematical fact that 23! equals 25,852,016,738,884,976,640,000, and the medical terms "hyperacusis" and "diplacusis." Participants also touch on humorous observations about life, such as the impact of television on weight and the emotional sensitivity of Barn Owls.

PREREQUISITES
  • Understanding of basic mathematical concepts, specifically factorials.
  • Familiarity with woodworking techniques, particularly historical methods like oyster veneering.
  • Knowledge of medical terminology related to hearing, such as hyperacusis and diplacusis.
  • Awareness of cultural references, including the significance of historical events and figures like Muhammad Ali.
NEXT STEPS
  • Research the historical context and revival of oyster veneering in woodworking.
  • Explore advanced mathematical concepts related to factorials and their applications.
  • Investigate the medical conditions hyperacusis and diplacusis, including their causes and treatments.
  • Learn about the emotional behaviors of animals, particularly Barn Owls and their sensitivity.
USEFUL FOR

This discussion is beneficial for woodworking enthusiasts, mathematicians, medical professionals, and animal behaviorists, as well as anyone interested in the quirky facts of daily life.

This kind of crazy?



Today, I learned to stay off the north jetty of Humboldt Bay(coordinates: 40°45′53.06″N 124°14′05.01″W), when the National Weather Service issues a High Surf Advisory for Northern California after overnight measurements indicated a surf height of 27 feet.

Sure that crazy is the appropriate adjective here?

Just Wow!

hmmmm... Are you implying that it's going to be crazier?
Could be.
But my imagination only goes so far, and the next 4 years is only a week old, and many of us are already... :oldfrown::oldmad::oldeek::oldsurprised::oldsurprised::oldsurprised::oldsurprised::oldsurprised:

We may need a new adjective.

That is not crazy, that is a suicide attempt.Today I learned: There was never a proper randomized double-blind trial on whether parachute use prevents death when jumping out of airplanes.

More likely skewed results from those who couldn't report back the failure of their jump.

Today I learned that just because Windows Update has been saying "Checking for Updates" day and night for 18 days (with the Windows Update service under svchost.exe showing 100% CPU for all of that time) that doesn't necessarily mean it's not making progress!

This morning, I found it had just applied 40 updates and had two more ready to install, after which it now reports it's up to date.

This is a Windows Vista system that I hadn't used since July, when I tried but failed to update it to Windows 7 (which it claimed should be compatible), getting some extremely obscure error in "specialization" processing after it had all apparently installed fine, probably due to the hard disk having been replaced a couple of years ago by someone who didn't do the right incantations to initialise the new disk correctly for Windows. Or perhaps the disk controller doesn't support the new disk properly. Or it's a side-effect of a known bug in the original CD version of the Windows 7 Update package to do with RAID controllers. Or something. Or something else. Grrr.

Yeah, my bet is it's your last suggestion, "something else". It's ALWAYS "something else" with *&#^@%%# Windows.

TIL about Göbekli Tepe while reading Sapiens: A brief histry of Humankind by Yuval Noah Harari.
It “is an archaeological site atop a mountain ridge in the Southeastern Anatolia Region of modern-day Turkey, approximately 12 km (7 mi) northeast of the city of Şanlıurfa.”
What is fantastically unusual about this site are the very large carved monumental structures built there

about 9500 BCE by hunter gathers rather than by farmers who archeologists have determined have built all other similar kinds of structures found so far.

Heh. I've actually been there.

Also, why it isn't a TIL, I would like to ask you lot: How do you "learn" all those things? For example I learn something every day, but forget in a few days/weeks. Do you write them down too? Or just not care whether you'll remember?

If we all used spaced repetition we could remember all those facts almost forever!

Hi @Nugso:
I generally bookmark or download stuff I learn. Most of what I learn day-by-day is that I have problems understanding what I am learning. I don't post about those things as a TIL item, but very occasionally I actually come to understand something, or at least I am pretty confident that I have, and then I post about that. When I learn something I don't understand, I sometimes start a thread to seek someone who can explain it to me.

Regards,
Buzz

Previously IL that some fish can communicate via their farts!

I wasn't aware fish were farters, so that's kind of a 2 for 1 deal there...

On the other hand I'm not sure I want to remember this one.

I see. I'm currently taking notes of what I'm learning every day such as Nuremberg Trials and hCG. Would be good to remember them forever!

Today I learned what might be the loneliest job in the world.

https://sputniknews.com/art_living/201702021050289083-austrian-town-loneliest-job/
The local community in Saalfelden, Austria, offers one of the loneliest jobs in the world. The locals are looking for a hermit, who is expected to live in a hut in the mountains without any modern facilities.
The person who will be chosen for this position will have no access to electricity, heating, internet or even a salary.

The applications are being received by a local priest, Alois Moser. Several applicants have already demonstrated their interest in the vacancy.
