>>7641586 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.
>>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 ).
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.
>>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. What are your achievements math guys? Shitposting on /sci/?
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... Comment too long. Click here to view the full text.
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... Comment too long. Click here to view the full text.
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... Comment too long. Click here to view the full text.
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? >also general robot thread
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...

>>7641106 >>7641108 where am I wrong? I mean obviously it has to get from solid to gaseous form somehow, is this not what heating accomplishes? and obviously the chemicals are not combusted, or they would change into different chemicals.
>>7640898 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.
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...

>>7640669 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... Comment too long. Click here to view the full text.
