AI Thread Summary
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.

No!
It's supposed to mean; "I know nothing".
I guess it's my fault, as I broke one of my own rules:
1. No googling
2. Must be learned from a speaker of the language.​

This phrase, was relayed via a friend from his father.
The only phrases my friend knew, off the top of his head, were; "Aba ab dawd", and "Sho macha tori".

How do you say; "I am a failure". :headbang:

I purposely never post foreign phrases, such that they can be googled.
And always, a bit off, phonetically.
You can catch googling "fakers" much easier that way.

Sometimes it means "I know nothing about that subject", so I guess that was correct!

"I am a failure."= "Man yek bazande am"

Today I learned that average hair grows half an inch per month.
So that means if I shave my head, hopefully it will grow back very soon:approve:

Funny - I looked up exactly the same thing yesterday. But if your head has to grow back after shaving it, I don't think you're doing it right.

I learned that if I accidentally take some frozen food out before turning the oven on, and the food is not supposed to be defrosted beforehand, it's okay. I don't have to put it away, the food will still be quite frozen by the time the oven heats up.

I also learned if you have a cardboard box you're trying to shut, one of those ones like pie box that the lid folds down and the sides of the top half have to fit in under the sides of the bottom half. Well I was having trouble shutting it and I noticed it was getting stuck on the contents of the box. So I shut the box one side at a time, each time tilting box away from that side so the contents shifted away. So I learned how to close this box. Actually that was yesterday.

Shaved heads look clean.
I learned that we shouldn't shave our pubic hair because our skin around our genitals may lose its membrane which is good for warts or bacterial infections. http://www.ncbi.nlm.nih.gov/pubmed/22362688

Today, I learned that Opossums have 13 mammary glands.
I learned this, because I saw a video, of what I initially thought was some Sarah Mclaughlinesque mangy mutt rescue video. But it turned out,



that it was just a very healthy looking Opossum, with, IMHO, way too many babies.

Not having been aware of odd numbers of mammary glands, I was unable to picture where the 13th should be. I of course, googled that.

12 are in a circle, and the 13th, is in the middle.

That is interesting and just think, the babies can find all 13 without any instructions. :D

Without goggling I have no idea what all that meant :oldconfused: so now I have some study ahead and I'm not sure why I would want to know, other than Om said it, What's wrong with my life at this stage ??:oldfrown::oldsurprised::D

Today I learned that when my computer screen all of a sudden looks like I have been bumped off line, all I have to do is put the cursor on the internet explorer logo and click. All of a sudden it is all back and I haven't even lost what I was typing. OK so what are the keys I am inadvertently dragging my numb fingers over. I learned today that the space bar is one of them.

Is it the punishment that I deserve for using internet explorer?

The appearance of Bandersnatch here prompted me to finally look up the term. I have never read any Lewis Carroll stuff. So today I learned that, all linguistic cues to the contrary, a "bandersnatch" is not in fact a chastity belt. I now take my leave.

If you're using Windows 8 it can happen if you move your cursor to the bottom right corner of the screen.

Today I learned that

Code:
\usepackage[hidelinks]{hyperref}

doesn't work in Polish. Despite already having

Code:
\usepackage[utf8]{inputenc}
\usepackage{polski}
\usepackage[polish]{babel}

chapter title links don't support all Polish national characters, only some of them. To get them displayed correctly you need

Code:
\usepackage[hidelinks,unicode=true]{hyperref}

Awkward if you ask me.

Today I learned that the Cleartune app on my Samsung Galaxy SIII mini phone is accurate enough (over most of the range, anyway) for me to tune the three piano strings for the same note separately so that they don't have an audible beat when played together. I'm surprised it's able to give results that accurate.

Tuning my piano is not easy even for the experts. I'm on my third piano tuner, as the others found it too frustrating. It's a Young Chang G-157; sounds good but somehow eats its way through the steel strings in the second-from-highest octave; they get a notch where they run under a bar, which gets caught during tuning, causing it to tend to lock into a specific pitch even if it isn't quite right, then eventually breaks there.

i looked up what the ok sign means on my avatar.
http://en.wikipedia.org/wiki/A-ok
apparently, in the buddhist context it is the transmission of buddhist teaching,
while in the christian context it is seen as 666, the number of the beast.
arabs consider it a threatening "youll see"
and in spanish countries, it means anus or homosexual
learn something new every day lol
personally i tried finding a lotus position first, but couldn't find a good one.

Today I learned, that math still works.
My newly found cousin seems to believe that on January 5th, a planetary alignment might make her kind of weightless. She's not really sure.
It kind of reminded me of the "The Earth floats in space because it's filled with helium" theory.
Anyways, I did some recreational mathematics to see what kind of alignments would result in weightlessness, and the consequences.

Scenario 1: Another Earth perched on her head.
Acceleration of the two Earths towards each other: 2.45 m/s2
Result: flat cousin in less than 2 seconds

Scenario 2: Earth moved closer to sun.
Distance from surface of sun: 3,000,000 km (as a comparison, Mercury is 70,000,000 km from the sun)
Solar insolation at that distance: 2,300,000 watts/m2 (we receive about 1000 watts/m2 here on Earth)
Result: severely sunburned cousin (This is just a guess, based on the fact that Mercury has a maximum surface temperature of 800°F, and lead melts at 620°F)

I also offered a "definition" inspired option:
Scenario 3: Jump! (Which is actually what the article said she had to do on that day, so I mentioned that it was half right.)
Result: momentary weightlessness, without all the nastiness. :)

Moore told scientists that they could experience the phenomenon by jumping in the air at the precise moment the alignment occurred. If they do so, he promised, they would experience a strange floating sensation.
:D :DD :oldlaugh:

Jeepers Creepers - written for a movie in 1938, performed by Louis Armstrong who in the movie was a horse trainer and sang the song to a horse...named jeepers creepers. Also in the movie...Ronald Regan.

"The phrase "jeepers creepers", a slang expression and minced oath euphemism for Jesus Christ, predates both the song and film." Wiki
