and now for something completely different…
In the USA and other countries, turning your glass upside-down might indicate that you do not want any more to drink. In Australia (so I’m told) it might signal that you can win a fight with anyone present.
Authentic signal exchange between Atlantic convoy escorts during WWII:
(A) commence hostilities with Japan immediately
(B) request permission to finish breakfast first
A topological space is connected if and only if the only non-null subset which is both open and closed in T is T itself.

lauramarlane, the arm span thing is only for some people. My arm span is 6’6" and I’m about 5 and a half inches shorter than that :slight_smile: Yay genetics.

Tritone: Its the canker sore one. Its almost the same virus, but the one that 85% of hte people have has a mutation in its gene coding for its envelope protein (think a cell membrain but for viruses, allows for protection and increased infectivity). Its actually really cool… At some point a specific batch of nerves are infected with the simplex virus but they mutate. Now its a latent infection (the cells stay infected, but don’t die (either from viral release or from the immunesystem)). The nerves that are infected are painreceptors in your mouth and gums, when you’re immune system is suppressed (stress, other illnesses and what not) the virus is able to produce a SMALL amount of infectuous particles, the virus travels down the nerve pathway and infects the tissue in your mouth!

There is a danger with this virus however: The nerves that are typically infected are VERY close to some nerves running to the eyes, and in .01% of the cases (or even fewer, can’t remember anymore) an eye infection can result, which may lead to blindness.

Apparently the drug to treat genital herpes outbreaks also works with the mouth sore version.

And I don’t buy the 80% of fecal mass is bacteria.

My useful tidbits:

Using ethanol to disinfect surfaces only works on enveloped viruses and bacteria. Since ethanol disrupts lipid bilayers.

If you try to dilute raw ethanol with water, say making a 75% ethanol solution out of 750 mL of 100% ethanol and 250mL of H2O, your final volume WON’T be 1liter! If I had actually gone to any of my chemistry classes and stayed awake I’d remember why. It has something to do with hydrogen bonding…

In chemistry there are rare reactions that are cyclic. A goes to B goes to A goes to B… The energy for activation for both is similar, and very little or no substraight is lost in the reaction. There’s a cool one where you mix stuff up and its red, add a stir bar and start it stirring and it’ll suddenly go from red to blue, let it go longer and it’ll go back to red. I’ll keep doing that for a while.

There is an old test to determine the properties of a compound to kill living cells where you take a vial of blood diluted with PBS then you add teh compound. You then hold the vial up to a page in a book and when you can clearly read the text through the vial. The amount of time it takes until you can read the text tells you how good of a lytic agent it is.

Okay, here’s something marginally useful.

How to Fake Talent in Writing Poetry

My mom taught me this a few years ago, and it’s worked in every single Creative Writing class I’ve ever taken.

  1. Write a sentence.
  2. Remove all punctuation (commas, dashes and quote marks are optional.)
  3. Throw in a couple of line breaks at random places.
  4. Repeat if necessary.

Works like a charm. Try it.

Little known historical fact:

Julia Child was an OSS agent in WWII, and infiltrated into German-occupied France to work with the French Resistance.

Here’s one from anatomy-for-artists: Lay your forearm on a flat surface, palm down. Keeping the elbow firmly planted, turn your palm up. Turn it down. Do this over and over with the realization that your ulna and radius are actually crossing over each other. Try not to puke. :smiley:

Calf’s-foot jelly is the forerunner of the now innocuous Jell-o.

Your home will be more susceptible to forest fires if you put it at the crown of a hill or ridge, as hot drafts travel upwards.

NO! You’re telling me my micro lecturer LIED to me??? AAAAAARGH! If he lied about that, then maybe he lied about other stuff too… like how to treat Neisseria meningitidis, and the non-pyogenic complications of Strep. pyogenes infections, and and and…
Finagle, I really don’t need that kind of doubt so close to exams…

Oh, and CRorex, according to my sources (no, not the lecturer quoted above!) about 85% of people have the HSV-1 (coldsore-causing) type of Herpes simplex, but a good few (around 40% of sexually active adults in Western societies) have HSV-2 (the genital one) as well. Treatment of genital herpes is with acyclovir, valaciclovir or famciclovir, but these are generally only given as short-term courses to control attacks. I’m not sure whether it’s possible to eradicate the virus completely; suppressive therapy requires long-term use of antivirals.

Cool about the cell mutation, though!

No, Inky-, absolutely not!

beegirl13, I originally read that in a Bathroom Reader. That, or a book of weird facts. But I do remember seeing that in Voyager as well.

More little known historic facts:

In the olden days many dutch bakers had a little room in the back where clients could “meet” the girl (usually the baker’s daughter) behind the counter.

When Tsar Peter the Great visited Amsterdam he spend a considerable amount of time at bakery van Schoorl.

Those crazy licentious Dutch, prostituting their daughters at the drop of a hat! Do you have any kind of a cite for this?

To be honest no I haven’t.

It’s from a book I once read about the 17th century writer Jeroen Jeroense who travelled around holland and collected sayings and writings on signs and plaques. Some of those plaques had some rhymes that alluded to this fact, and so did the writer.

In fact If anyone knows the book I’m talking about I would much obliged, but for now you’ll have to regard unsubstantiated.

Sorry :frowning:

This came from my doctor a little while ago. We decided it was just the surgery on my shoulder, but I stocked up on liverwurst just to be sure.

If your blood test comes back saying you’re anemic, you can get a diagnosis (or a first cut at one anyway ;)) from the size of the red blood cells.

Small: Lack of iron (or poor absorption), or a genetic disorder called thallasemia.

Large: Vitamin B12 deficiency, formerly called ‘pernicious anemia’.

Normal size: Loss of blood, one-time or ongoing. Mmmmm! Liverwurst!

bannana is not actually a tree, it’s the world’s largest herb

The song “Amazing Grace” can be sung to the tune of the “Gilligan’s Island” theme song AND the old Coca-Cola jingle.

Every single poem by Emily Dickinson can be sung to the tune of “The Yellow Rose of Texas.”

“The Star-Spangled Banner” was not set to music originally, and has a crapload more verses that most people don’t know about.

Here’s another way to measure the height of a building, or other tall thing (a tree for example):
Get a mirror, a tape measure, and something to write with. Stand some distance from the object so that you can see its top. Place the mirror on the ground so that you can see the top of the object in the mirror. Now measure and record the distance from your feet to the mirror, the mirror to the base of the object, and the height of your eyes from the ground. The proportion of the object’s height to the distance from the mirror is the same as the proportion of your eyes’ height to your distance from the mirror.

How to tell the amount of time until the sun sets. I think this probably only works from mid-afternoon on, but I don’t know this for a fact.

Make a fist.
Count how many fists fit between the bottom of the sun and the horizon.
Each fist length equals one hour (or a finger is 15 minutes).

This will approximate the time til sunset.

The New Zealand Moa was the tallest bird in the world. There were 11 species of Moa, ranging from the size of a large chicken to over 2 metres tall. The Maori killed-off the Moa before Europeans arrived in New Zealand.
It is estimated that the Maori killed-off 50% of all bird species before trying to conserve them, then Europeans came and killed many more.
Before Maori arrived in New Zealand (about 800 years ago but under dispute), the noise of the birds must have been deafening!

There are no native land-based mammals in New Zealand.
