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.
>>7641565
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 ).
What's the evolutionary purpose of baldness?
why did human body decide to just let the top of your hair disappear?
>>7641523
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.

why aren't you an astronaut yet
>baaah it's too hard
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'm not an american
>>7641502
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.
Ivan Zelich, 17 years old boy, has done something groundbreaking and his discovery is going to change the world drastically. This kid is the real deal, not Jacob Meme.

Lol. Butthurt you'll never have an IQ that high, OP? Its alright, maybe people smarter than you will discover a way to cope with living as a dummy :)
The first person to accurately decode this 17 digit cipher will get a $50 Steam Gift Card.
I just want to see if you can do it.
Good Luck Anons.

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...

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...

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...

have people been dying in significant numbers of anomalous poisoning from toxic chemicals, such as those mentioned?
No?
In terms of how the commands work and what they do

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?

They come in kits these days, pretty easy from any angle you come at it.

He look like real good looking monkey in this photo. must because of it's nasty long beard and hair.

yes
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...

That's wrong

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

You can keep an object moving straight forever in a 0G vacuum due to inertia
Impossible.

That's not infinite energy though. If the system doesn't have continuous net output it's not a "perpetual motion machine."

I don't see why they can't whip one up and strap it to a satellite or some kind of fairly simple probe and give it a test run
Like keep testing it sure, but multiple of these things have been made (since multiple places are testing them) so surely it would be worthwhile to actually field-test one and see if it holds up outside of a laboratory setting.

wow pleb
What does /sci/ think of timed tests? I think they are bullshit.
My chemistry professor gives us a timeframe on our exams so we have about one minute per problem. Now, I understand everything conceptually, but math is not my strong point, so I need time to set up full dimensional analysis or work through calculations in a formula a step at a time, and doing this I get most of the practice and homework problems right, but I only get low B's and C's on exams cause with the time limit not only is feeling rushed working against me, but he expects us to know immediately...

there is a difference between solving the problem in 1 minutes and 10 minutes. you challenge yourself to work faster. whats wrong with that ?
I agree with you, but what are you going to do, fail? Man up and get gud. Become exceptional.
>>7640804
Their is no math in chemistry that should take longer than a minute. You don't know the concepts

How bad is glyphosate?

About as bad as people's comprehension of basic ecology, evolution, and glyphosate's degradation rate. Have fun dumping on more and more to combat an increasingly resistant population. Have fun with that soil accumulation.
Round-up ready is garbage, laughable, infantile engineering. Genetic engineering has potential as of yet far untapped. This fucking irresponsible joke is not something to applaud, it's a disgrace. It's banal. It's shameful.. Unfortunately, real innovations like won't...
