going back to a capsule design?
why did NASA decide to go back in time?

It works. I guess. I feel that trying to further improve the shuttle would be beneficial, but ...no funding? I guess. Idk.

If there are trig functions for circle and ellipse does that mean you can make any trig function out of any closed function?

Paul Dirac was dating Jane Russell. They went out for a walk, and tripped. He fell on top of her, and someone said, "Hey, look at Dirac on Jane Russell."

To Canadians, British, Irish, Australians, New Zealanders, Jamaicans, anyone else from an english-speaking country with ties to the crown: What units do you THINK in, imperial or metric? What about older people that you know? Even if you have an intuitive sense for both units, you must be more comfortable with one or the other.
I was under the impression that none of these groups used imperial at all anymore (except colloquially/informally), but my brother (we're US native) recently visited a far-off relation in rural England and told me he was surprised to see some road signs in miles. Our relative told us that many people still consider imperial units to be their first nature, although young people in urban areas don't. I'm wondering what others think. Is it similar in commonwealth/other english speaking nations?

Canadian here. I think in imperial because that's just what everyone around me used. That's what they used when I did carpentry.

Why and how are pi and nested square roots of 2 related? How to derive Vieta's formula from this for example, or vice versa?
Please give insight.

I think both stem from iterating sin- and cos- relations to each other.

the last squareroot is unclear to me. it says sqrt(2 + ... + sqrt(2)). what happens at the "..."?
>>
Pi is the arc length of the curve y = sqrt(x^2 + 1), so you take an arc length integral to get this interesting thing as an intermediate step if you work the integral in a certain verbose way.

Ive got a giant inflatable cloud I'm trying to get 15ft into the air with a 20-40lb payload capacity. the balloon has a total interior volume of 5,660ft^3. how much helium do I need to fill it with? the material its made of has 4mil perforation. any of you balloon or blimp experts?
pic related, similar design but mine is larger.

why would ants need to lift 20-40lbs?
At any rate, do as professional ballooners do and just fill until it is doing what you want. You're going to end up having to fudge your numbers anyway because things like ambient temperature and insolation are going to fuck up your calculations anyway.

>>9151153
I need to know how much helium to order.
>>
>>9151157
1.) look up typical carrying strength of a common weather balloon
2.) look up how much helium is used in a typical weather balloon.
3.) use more or less, depending on carrying strength of weather balloon.
research is important.

Anyone have experience with DIY transcranial stimulation devices?
Ive just completed one and I think I did everything like I was supposed to. A bit nervous to try it out on myself though.

Looks like he intends to fry his brain. OP skipped past the part of the instructions where they warn people to never try stuff like this without some serious engineering experience. And I see waaaay too much tape to indicate any sort of serious engineering experience.

Want to see if it makes me less depressed
is it possible to have better than 20/20 vision with contacts?
for example if my prescription is -3.00 (assuming this gives me 20/20), will bumping the prescription to -3.25 give me better vision?
Or will bumping the prescription give me better far vision but it will make my closer vision blurry?

Take a look at how contact lenses work and it will answer your question.
>>
>>9151102
Yes.
>>
>>9151102
or glasses or lasik, yes. But your eyes are lazy fuckers and will adjust to not needing to focus as hard so you'll have to keep upping the prescription until you can't see a damn thing.

>tfw you realize that it's impossible to be a decent mathematician unless you were a child prodigy
Literally anybody with a three digit IQ can be an experimental scientist or a code monkey. But the really interesting stuff is inaccessible to us brainlets. We will never truly understand mathematics the way that Gauss or Ramunujan did. They are gods in comparison to the average man.
