Where will you be on August 21, the day a total solar eclipse crosses over America for the first time since 1979?

This might be one of the most viewed eclipses of all time since it's not in the middle of nowhere like eclipses usually are.

I want to have a thread on human speech/language pathology and didn't know where else to do it so /sci/ it is

I have been studying linguistics as of late and it's actually very interesting stuff. Does anyone else here give a shit or should I just fuck off back to ®eddit?

Why the focus on removing Africa's carbon footprint?

I've come to notice that a lot of inventions designed for African tribes and other struggling communities that the main focus is things like their carbon footprint, instead of things like their lack of proper health care or manufactory. Like, wtf?

Why focus on making solar equipment for water purification and food cooking and transportation and then say, "It reduces their carbon footprint," when any American driving an automobile already has a carbon footprint at least a dozen times larger than one individual? It'd make more sense to cut the carbon footprint by putting air scrubbers on factories and vehicle exhausts or investing in Hydrogen fuel cells than limiting the abilities of the poor.

Is there a red-pill meme about keeping the poor in their place I'm missing here? It just doesn't make any sense. Using a solar dish to replace bonfires that burn trash and cook food and calling that reducing the carbon footprint when doing absolutely fucking nothing about Chinese industrial pollution or American food production pollution makes no fucking sense.

>A drug discovered more than 100 years ago may hold the key to combating autism symptoms, according to a study.
>Researcher Dr Robert Naviaux of the San Diego School of Medicine gave suramin, a drug first developed in 1916, to 10 autistic boys between the ages of five and 14, and noted transformative results.

>"After the single dose, it was almost like a roadblock had been released," he said. “If the future studies show that there’s continued health benefits, this could be a game-changer for families with autism.”

can an old sub be turned into a orbital launch vehicle? i figure it'd be more economical than trying to make one from scratch where you need a whole team of welders to make the fuel tank. or would dismantling this take as much manpower?

I'm tempted to say to myself, "just work hard bro", but the point of being a high IQ person is that you should be getting the fucking answer, not having fucking difficulties. Being a high IQer means being good at doing, not having a certain amount of knowledge.

This is a brutal feeling. And I got top marks in my high school and university engineering maths courses (I am studying applied maths after finishing university).

Dear /sci/. I almost fucked up royally by letting a mercury lamp almost explode. My supervisor uses it, its worth a few thousand euros. It said in the manual to not let the power go beyond 110 watts. You have to keep checking whether it is close or over this value every few minutes.

What do i do? I turn it on, leave the room, look at memes for about 15 minutes. I come back and lean over to look at the lamps. the mercury lamp is now directly under my head. It feels kind of hot, let me look at the power it is producing.

HOLY SHIT IT'S 115 WATTS!! GREAT SCOTT!
I'm shocked and after some moments being frozen i turn the value down. nothing exploded, no harm done. But i feel like shit, what if the thing exploded. In my face? i would have died, or ended up disfigured for life...

But what if the thing exploded when i was not near, evenm then i would have been majorly fucked. My research gone to shit togheter with any grade i hoped to get.

I still feel like total shit and I needed to vent...

Thanks for reading!

Did the infinite complexity of the universe arise from absolute simplicity? Did this really all come from nothing?

Today I learned what double integrals are and even though in class we only saw really trivial examples (planes) and basically just covered the limit definition, when I got home I got myself some practice problems and learned all the little tricks like changing the order of variable and subdividing the region being integrated over.

And I have to say, doing double integrals makes me feel really good about myself. It makes me feel really smart. I am not sure why it is, but if it is anything then it probably is drawing the double integral symbol, writing dA, and specifying the region of integration under the integral as a set, rather than as an interval. Also when I say the word compact I feel like a big man.

Compact. Compact. Consider this compact set. Consider this family of compact subsets. Consider consider consider. Let A be a partition. I want to fuck a double integral.

And just now I was doing retarded shit as always like jerking off and watching dumb 4chan simulator videos on youtube when suddenly I remembered how good it felt to do double integrals, so I looked for more problems and just did them. It legitimately felt good to do those integrals and now the feeling has stuck in me. I may just see myself in the couple of weeks doing double integrals at the park, at the bus, in my room, in the bathroom while taking a shit. Who knows. Double integrals may be the best concept in mathematics that has ever been invented and no one can deny this to me. And I have felt so good that I have come here to you to preach about the one true god of mathematics: double integrals. Have you done a double integral today? Have you thanked the gentle authors who created double integral problems for us to solve? Thank them or you will go to integral hell, where there are only single integral problems and where compact sets do not exist.

So comfy.
