Is "scientific illiteracy" really a problem or have we been meme'd by wannabe scientists trying to sell books?
Are you >imblying neuroscience isn't science ?

it's a problem when scientific illiterate kongressmen/taxpayer pull the plug on important research just because they don't understand why it's important.

It began with the Big Bang.

From nothing
How the fuck does "Common Core" work? What is this fuckery?
consider the following:
solve 15 - 11.
1) 11 + 1 = 12
2) 12 + 1 = 13
3) 13 + 1 = 14
4) 14 + 1 = 15, which is exactly what we wanted
adding up 4 of the 1's we get 4, hence 15 - 11 = 4.

So that's what that fucking lecturer was doing. Some intro maths lecturer at my Uni was trying to show something like that and everyone was confused as fuck. Didn't help that the guy was ESL.
Seems slow and pointless.

Common core is written mental math for retarded people that can't into mental math by themselves ( and generally it just ends up confusing them just as much if not more, as their retardation is genetic and not due to a flawed teaching method ).

why did human body decide to just let the top of your hair disappear?

There isn't, bald people just still kept getting laid (likely before they started balding)
It shows how beta you are. Women find it disgusting and you end up killing yourself. Better hair genes gets more pussy.

these are the requirements on the official website
Applications doesn't mean they will send you to pluto right away. If you had even a tiny bit of surgery that can cause a health risk, or any condition that can even remotely cause you to risk the health or lives of the crew members, they will disqualify you immediately.

I actually don't want to be an astronaut and don't even know why people would want to be one. I might fail to see the appeal. Or it's just an american meme that survived the "end" of the cold war.

What Chemtrails are, and why they're real
Coming to Face the Facts
I, like any denizen of the internet, have come across the cornucopia of crazy conspiracy theories, from the plausible to the ridiculous, to the type that are so nonsensical that one can’t be sure they’re not a parody of the ridiculous. One of these, which I’d classified as the second category (clearly ridiculous, but obviously not a parody as people seriously believe it), was that of chemtrails. In short, “They” are spraying chemicals from commercial airliners (which typically cruise around 35,000 feet above sea level) for various nefarious purposes, ranging from mind control to mass-sterilization.
I chalked this up to being ridiculous because, to put it simply, it never really made sense to me. First, what chemicals would be sprayed, and how they’d be at all good at being distributed across populations when delivered over six miles above the populations they’re supposed to be affecting. Second: what these chemicals are supposed to be doing; the sterilization thing is obviously not working. And third: just how big is the conspiracy. Are all airliners in on it? The pilots? If so, how has it been kept so secret for so long?
After I got my private pilot’s licence, I began to have doubts. I learned more about planes, and realized that the conspiracy not only doesn’t have to be that big, but it actually is happening. Not only that, but I now can say with some certainty which chemicals are being used!
2/3
Chemtrail Composition
Chemtrails are, as the name suggests, trails of chemicals, in this case specifically those left by high-altitude aircraft. Some chemtrails may linger for hours, while others seem to vanish within minutes. However, even those that visually disappear to not actually disappear; it’s just that the majority of chemicals released are colorless and odorless, but no less dangerous.
The primary component of chemtrails is hydric acid, which, like the other ingredients I’ll talk about, has the worrying ability to dissolve completely in water. Hydric acid is special in that it’s what is visible in the contrail, as it’s triple point—the temperature and pressure at which it can exist as a solid, liquid, and a gas—is close to normal atmospheric temperature and pressure. In its solid form, hydric acid is reflective, which is why chemtrails appear white.
Hydric acid has odd properties, and was used extensively by the Nazis, who mostly studied how long it took people to die when exposed to lethal amounts of it. It’s corrosive, to the point of being able to dissolve rocks, and is a greenhouse gas, though you won’t often hear it talked about because it’s effects are deemed minor and inconsequential.
Another major component is carbonic anhydride. Carbonic anhydride is acidic and corrosive when dissolved in water. It’s deadly to humans (when present, it prevents the lungs from absorbing oxygen), and when placed in seawater it has been shown to bleach choral and even dissolve the shells many marine creatures produce to protect themselves.
Finally, I’d not be doing my job without mentioning that carbonyl, a highly toxic chemical, is also present in chemtrails. Like the others, it’s colorless, odorless, and tasteless. Remember: just because you can’t see it, smell it, or taste it, doesn’t make it any less dangerous!
3/3
Why Chemtrails?
Here, I can only enter the realm of speculation, based on the aforementioned three deadly ingredients of this toxic soup. Because carbonic anhydride and carbonyl are both deadly, with the former being heavier than air (and thus tends to sink to the ground), one possibility could be a mass extermination campaign. However, the primary ingredient seems to imply ulterior motives.
My theory is that chemtrails are a form of chemical geoengineering. After September 11, 2001, when all air traffic across the US was grounded, studies showed that the lack of chemtrails actually changed the weather patterns from what, until then, had been considered natural! It’s probably not a coincidence that airplanes release the cocktail when at high altitudes, where hydric acid becomes reflective (though even when not reflective, it’s still a potent greenhouse gas!).
So I hope you learned something from this whole thing. Hopefully soon the public at large will be educated enough about these things to be able to make informed decisions about the quality of our air.
have people been dying in significant numbers of anomalous poisoning from toxic chemicals, such as those mentioned?
No?

Dunno, hardest I've used is R t
Assuming complicated, but not unnecessarily complicated, I would go with assembly language. Otherwise, I would go with Arnould-C.
what the hell does hard mean in this context? tedious? then probably x86 or one of those gimmick languages like chef
Is getting a programmable robotic arm worth it? I figure it would be a good hobby. I have a strong background in hydraulics/electronics, so would the programming part be hard to pick up?

so i was being a smartass the other day, and told my friend who vapes that even though its called "smoking", you never actually want to burn what you're trying to smoke, even cigarettes, marijuana, etc. he doesn't believe me at all, so i figured you guys could settle this.
my reasoning is that burning (ie combustion) will destroy nicotine/THC/cocaine/meth/opium or whatever youre trying to smoke, chemically, and that smoking a cigarette actually works by burning a small amount of material and paper in order to get the solid phase nicotine right next to it to vaporise into gaseous phase and go into your lungs. and vaporisers do the same thing, but they use electricity to heat it enough to vaporise, thus excluding smoke.
its seems like chemically sound reasoning to me, am i right or wrong?
>inb4 calling me autist/smartass/asshole for correcting someone
its just a fun fact chill

I had an argument over on 420chan a few years back with some idiot who thought that candle's don't burn, but rather, they vapourize
