I recently got into a debate with an idiot about what makes airplanes fly. He expounded his belief in the correct answer which was completely wrong and despite my constant attempts to disprove his idea and indicate the correct one, he would not believe me. It seems that there is a strongly believed and widespread misconception about what makes airplanes fly. So, without giving away the real answer, I come to /sci/ to ask the general populous here what they think causes airplanes to stay aloft. Who thinks what and why?

Close but no cigar.
We know that hypoglycemia is less 70 mg/dl and hyperglycemia is greater than 200mg/dl. But from what method exactly are we measuring these values because there are several different methods. Capillary blood, glucose fasting, glucose tolerance and glucose 2 hour postprandial. I'm assuming it's the capillary test.
Diabetes is defined as a repeated fasting glucose level of above 7 mmol/L. Venous blood is used for the diagnosis. Capillary blood is only used for self-monitoring by the patient.
The best diagnostic test currently recommended by the ADA is actually an HbA1c.
Other diagnostic tests are an 75g OGTT, an 8hr fasting glucose, or a random glucose >200 in a classically symptomatic pt.

T1 Diabetic here. Are you talking about testing BG for daily care, testing BG for how your overall health is going, or testing BG is see if one is diabetic?

Is this guy a meme?
He does some popularization, but he seems to pride himself on not explaining mathematical concepts in simple language--like an anti-pop sci.
For example, his book , Birth of a Theorem, has pages of raw manuscript with no explanation of what the equations mean.
But then again he dresses like that.
i would say he's a villain
>>7837219
He looks like a pompous ass that weighs about 130lbs and would get ko'd in 1 punch.
So some dinos evolved into birds...
Assuming humanity survives long enough, what might the humans of 100,000,000 years from now look like?
I'm aware we don't know what conditions they might encounter but, let's make some educated guesses.
>>7837205
Like birds, the true master race
It's possible that technology ends evolution. Why fly when we have planes?

This is what humans will look like in 500 years
If Human Beings are supposed to be evolutionary superior to any species on Earth, the ultimate predator, how come we cannot see in complete darkness? How come evolution did not supply human beings with some sort of thermal or night vision? Yes, man invented fire, but before that, we were completely blind at night against other predators. Why do we not have enough Rods in our Retina? This is not a Evolution vs. Creation debate. Just a curious question about Human blindness without a light source.

because the moon exists. Seriously, go somewhere away from city life and you'll be shocked how bright the moon is

So what about when the Moon is in a phase other than full? What if there is cloud cover blocking the light from the Moon?
At what age should one stop smoking in order to avoid serious health problems? I was thinking maybe late 50's/early 60's at the very least.
>>7837010
The best way to avoid serious health problems is to not start in the first place. Failing that stopping as soon as possible is probably the best bet.
>>7837010

Stop today.
Does anyone get annoyed when they see people getting euphoric about things like pic related?
Like they'll post threads with false color images like pic related (which are basically just CGI art by this point) and then have a hippie circle about the "beauty of the universe" for an hour.
I dunno why but this always irritates me.
Like I feel like they might as well be posting only the false color image on the right and then be having a circlejerk about the beauty of Mars
>>7836810
Yeah sure, but on the other hand we used to have those threads on /sci/.
We also used to Celestria/Universe sandbox jerk threads.
Let youngfags be young. At least they aren't doing drugs or worse; listening to rap.
Like http://www.universetoday.com/11863/true-or-false-color-the-art-of-extraterrestrial-photography/ even says from one of the people involved in this that "images are further adjusted to...make a more pleasing picture".

Does anyone on /sci use Ocaml? what's your thoughts about it?
I do. I like it a lot when I'm doing anything heavily algorithmic, or discrete math (I do most of my ProjectEuler problems in OCaml for instance, as well as a big part of the simulations I run for my research).
I don't really use it for anything script-like, or for things with a lot of UI work or IOs. It's not that it can't be done, but in my experience, the benefits it brings are not worth the annoyance.
I don't think it's a language everyone needs to know. I do think however that everyone that codes a lot should learn at least one...

I heard its module system is great.
I think it has no lazyness because Haskell failed that concept.

hi i am going to take algebrage and logarithm courses this summer
could someone give me tips for good boek
At the start of Winter (the first cold day in North Florida) I found a slug-like organism. It basically looked like pic related except it had absolutely no eyes. The back of the thing was very smooth and almost leathery. It was absolutely not a fungus because it moved across my windshield like a slug. It also responded to touch, it curled around my finger. While at work I did a quick little taxonomy check myself and could not find it under any North Florida Slug Identification Guides.

leech?
>>7836275
>it curled around my finger.
Why the fuck would you be stupid enough to let it do that?
You probably had a nice injection of parasitic larvae or some toxin.
So enjoy losing your arm from that you stupid fucker.
>>7836278
not a leech
>>7836279
It looked like it had a topside (Black) and a bottom (yellow) i didn't actually expect it to be a living organism when I first grabbed it and it was also extremely slow
I think it feeds off of detritus, but if this is the case, why did it make its way halfway past my windshield in the middle of dry, cold December?
Hey /sci/, I have an odd question.
Let's say there is a 10 km tall giant and, despite what the square-cube law would say, he is able to withstand his own weight and move like a proportionate human would through unknown means. His density is also somehow similar to that of a normal human.
1 - How much would he weight, assuming he is of average build.
and
2 - How far would he sink into the earth due to his weigh?
Go ask /tg/.

some quick math put our man at 14 billion metric tons.
I'm probably wrong though.
Why are there no green stars?
>>7836024
>Any star emitting mostly green will be putting out lots of red and blue as well, making the star look white. Changing the star's temperature will make it look orange, or yellow, or red, or blue, but you just can't get green. Our eyes simply won't see it that way. That's why there are no green stars.
Stars give off a broad spectrum. If the peak of that spectrum is "green," then it will look white, because green is right on the middleof the visible spectrum, so it will be giving off a lot of red and blue also.
Why are there like no green potatoes, man? How can our eyes tell that we're NOT seeing green, dude? Did you ever think about that, brother man?
I mean, what kind of app you could invent to make better use of our smartphones?
>>7835938
Phones come with a lot of sensors for motion, heat, altitude, etc.
I once got the idea about making an app that would allow a nice interface for all of those devices inside your phone to turn it into a small lab but I decided against that because I'd have to read a fuck ton of documentation and then months and months of refining and design.
As a mathematician (well, student of maths) that is simply not what I am interested so I dropped the idea and kept making dumb phone games because at least that...

>because I'd have to read a fuck ton of documentation and then months and months of refining and design.
I thought the OS did that for you and you get some simple API's as a developer?
>>7835966
It does. What you get are objects from which you can access the devices and the data they collect.
However, to do this you have to know the methods, their parameters and what not to do to fuck everything up.
It is not that much work really, a couple of hours of reading would be enough. You can try it if you want.
