Our new Indie Games subforum is now open for business in G&T. Go and check it out, you might land a code for a free game. If you're developing an indie game and want to post about it,
follow these directions. If you don't, he'll break your legs! Hahaha! Seriously though.
Our rules have been updated and given
their own forum. Go and look at them! They are nice, and there may be new ones that you didn't know about! Hooray for rules! Hooray for The System! Hooray for Conforming!

The planes designed to fly upside down have symmetric airfoils which have a coefficient of lift at almost exactly zero at zero angle of attack. So, everything is pretty much mirrored on the angle of attack. Look, there are thousands of airfoil designs out there and each have their specific purpose.
I understand the issue, and I am aware that the Bernoulli principle only applies under idealized conditions, after all it can be derived from both conservation of momentum and conservation of energy.
That was a pretty stimulating read, you have good physical intuition. What's your background?
Oh god. So many racist white people in the comments.
Yeah I saw your UPPP thread in H/A.
I had a UPPP done and my uvula was removed. I don't have a uvula! I am uvulaless.
I think there's enough racism to go around for everyone in that debacle.

The liver is a fighter though, it is estimated that a human liver could become 150-160 years old in use - no problem. Partial transplantations of the liver are no problem either, you cut out half of it, wait 5 weeks and both split pieces have grown in to the size of full livers.
Livers are the energizer bunny of the body. They do a lot of tasks too.
Actually the negative view of Satan is a Christian/Islamic thing. Satan does thing we consider bad in the Old Testament, but his role in Judaism is "The adversary", or to be more specific "the opponent." He's like that guy that always questions and challenges, not hates humanity and wants them to suffer in hell.
The needs of a city are impressive too- even if everyone in New York ate only a pound of food a day, that's still be millions and millions of pounds of food.
Actually, the biggest hurdle to longevity is the brain and nervous system. Just about every other part of your body is repairable or replaceable. Not only is the nervous system incapable of being significantly worked upon or transplanted, most studies show that the odds of sustaining a debilitating neurological injury (stroke) or disease (cancer, Parkinson's, tumors) increases to almost 100% along the age curve.
Just about all of your abdominal or thoracic organs (except genitals) can be redacted or replaced and work just as well, and so can your eyes for the most part.
However, people with genetic aberration are basically fucked. Sickle cell disease, cystic fibrosis, DIC patients? Your problems can't be solved with any amount of transplantation. Scientific advancement is your only hope.
She's merely batshit insane and opportunistic with racism as her primary excuse.
This always made me wonder why you couldn't remove part of the liver from someone at high risk for liver damage (say someone who just contracted hep C, or a chronic alcoholic who had not yet developed significant liver damage), freeze or preserve it somehow, then use it for a transplant 10 or 15 years down the line. I'm sure preservation is the limiting factor, but there have been huge advances in tissue preservation lately.
Here's a question similar to the airplane flying upside thing: I'm nearsighted, and I understand that glasses work by changing the focal point of light going through them. Why is it, though, that I can literally turn my glasses around and look through them backwards and still see perfectly fine?
Edit: Also I think the reason for helium in scuba tanks isn't due to anything with breathing but instead because nitrogen and oxygen at high pressures both become supersaturated in blood plasma and bubble out on return to low pressures, while helium doesn't and thus makes a good filler to keep you from breathing in too much oxygen too quickly and therefore getting oxygen dissolved directly in the blood plasma as opposed to just in the hemoglobin.
Probably because your lenses are most likely symmetrical?
That is an interesting question. Yes preservation is most definitely the limiting factor, cutting a liver in two and transplanting one of the parts to someone else is common practice. Not very common but it's done all over the world.
So you could most definitely cut your own in half and save one for later - if we had better ways to preserve it. At this point we can't just freeze organs, cold slows organs down and makes them last longer on their way to a transplantation but we're talking about hours here. Actually freezing organs would cause the cells to rupture and take irreparable damage (freezer burn) because all our cells contain large quantities of water.
Also more to the point is that hospitals generally won't transplant an already infected organ to a person - in your example the patient's better liver-half would already carry the hep C infection. The hypothetical transplant would make him better but he'd still be replacing a damaged liver with a slightly less damaged one. Guidelines differ though, I know that some patients with liver failure here in Sweden can be transplanted with liver grants that carry certain lesser diseases.
Well the lenses are visibly curved, but apparently after reading the curvature isn't important to the lensing effect but is just to reduce distortion.
In regards to the hep c thing, the patient is already infected with hep c so that doesn't really matter, and the consequences of further liver damage is likely small compared to the organ rejection and constant immunosuppressants needed for a graft from another person.
A better preventative measure would be to take a biospy of liver cells early in life and culture it. The liver - due to it's regenerative powers and relative structural simplicity - is a prime organ to be grown in vitro for transplantation, using those tissue-matrix techiques.
Ground-floor health insurance of the next century is totally going to be based on living tissue culture like The Island - just with less murdering sentient lifeforms.
Along this vein: due to the fact the Earth is rotating, the apparent direction of "down" is not toward the center of the Earth unless you're standing on the equator or one of the poles. This also gives rise to Coriolis forces on anything moving relative to the Earth (within the atmosphere, at least). One of the best examples of this is seen when an object is moving for a long time: the Foucault Pendulum is exactly such an object, and was used to demonstrate that the Earth was, in fact, rotating. (This principle extends to anything moving in the atmosphere as well, which is what determines the direction weather systems like Hurricanes rotate.)

I always thought it was funny that while hurricanes and typhoons pretty much always rotate in the proper coriolis direction from where they formed, tornados will occasionally spin the wrong way just out of spite.

Just the idea of an earthquake, though, is terrifying. I've never been in one, but I'd probably shit myself.

I'm kind of the same way with hurricanes, nothing less than a high cat 4 or cat 5 really worries me these days
What about a blizzard that leaves 3 feet of snow on the ground?

I learned that if you live in the dorm that gets power back 2 days before the others, you find out you have a lot of friends you didn't know about who want a hot shower.
My mom and dad got to spend over a month without heat afterwards, though. It's a good thing they had the dogs to keep them warm.
Now they've got a generator wired straight into the grid for the house in case it happens again.

I'm the same way (re: just a fact of life) with wildfires and, to a lesser extent, earthquakes.
But, you know, lolCalifornia
Maybe this doesn't apply exactly, but I recently learned that some doctors are questioning treatment for Hep C because it works on paper, they can get the viral load to near nil, but patients aren't living any longer.
For years, I pronounced "melancholy" as "me-ann-cho-lee". Learned it was "melon-collie" at an advanced age.
And apparently "victuals" is pronounced "vittles". I assumed it should rhyme with "rituals".
But those are just words, and someone else's idea of how to pronounce them. Shakespeare had like 8 different ways of spelling his own name. In the long run, consensus wins.

I used to think this until I took a meteorology class, but I blame Mr. Wizard.
He did a demonstration where he had a tub of water with a drain plug and put it on a playground merry-go-round. He spun it in one direction, and the water drained clockwise. Other direction—counter-clockwise. I missed the part where the merry-go-round represented Earth.
Wait for real?
Makes no sense, but whatever.
And here I had the exact opposite problems. I've only ever heard it pronounced, so I've always assumed it was spelled (and I've written it this way a couple of times) "vittles".
Huh, I didn't know this. That's not a word I would normally ever use in speech, but I've always subvocalized it as sort of like "rituals" as well.
Here's one most of you guys are probably getting wrong even as you read it: "dissect". It's pronounced like "dis sect", not "die sect", although the latter (wrong) pronunciation is gaining a lot of momentum simply as a result of how many people screw it up. It really is the prefix "dis" and the root word "sect"; the prefix "di" and the root word "sect" would together mean the same thing as "bisect", which would be pointless as that's already a common word. Also, it'd be spelled "disect" in that case.

Seriously, Z is reserved for special occasions. I don't believe people actually use it as much as microzoft demands. Ostrasising for instance.
That's just an American thing - you guys tend to lengthen the first vowel in any word you can get your hands on.

De-lurk activate. OK.
This is a nit pick but I think it's somewhat important: Coriolis force certainly does act on water swirling down a toilet bowl. It arises from being in a rotating reference frame. Any rotating reference frame. The Coriolis effect from the rotation of the Earth (which has a relatively slow angular rate) just gets fucking dominated. Typically by the geometry of the basin or initial flow conditions.
You increase the angular rate, as in the Mr Wizard demo, and you can bring the dominated effect out of the shadows and into the limelight. (I didn't know that term was from lamps that actually used EXTREMELY HOT lime--calcium oxide--as the light source).
Wait a second, how do other people pronounce titan then? Isn't that the root word for titanium?
It is indeed, but root words often have very little effect on pronunciation - consider logo versus logarithm, the omikron being turned into a long O in logo, but retained correctly in logarithm.
