I used to get mad at myself and hit myself in the head. I started getting headaches and now I wobble a bit when I walk after about a year I got over it, but now a year later, I'm mad at myself again, only now I hit myself in the chest. What kind of health problems can I expect? I've been working out lately, should I stop working out my arms before I become strong enough to hurt myself beyond repair?

I'm a poor Amerifag so I can't afford a fancy doctor or shrink.

Buy a punching bag, and depending on where you hit yourself you could do some damage but that applies to everything.

If by "viable" you mean "pays for itself" then not very. The moon has no resources nor strategic significance in the near future. Even scientific goals can be mostly accomplished by much cheaper rovers.

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?

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.

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.

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.

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.

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.

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.

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.

We also used to Celestria/Universe sandbox jerk threads.

Does anyone on /sci use Ocaml? what's your thoughts about it?
17 posts and 2 images submitted.
>>
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 heavily functional language, but any would do. If you word with a lot of discrete math or theoretical computer science however, knowing a bit of OCaml or another ML language is probably a good thing.

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.

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?
