SPACE ELEVATOR WHEN???

>>8340781
Looks good, and there's plenty of margin to work on making the orbital stages reusable.
I've seen a reasonable estimate that this will have a payload to LEO of 70 tons. So they can add 35 tons to the second stage in heat shielding, fins, and landing propellant, and it'll still have 35 tons to LEO capacity.
A 35 ton 3rd stage with a 450s BE-3 engine could propel about 20 tons to GTO. For an 8-ton comsat, that would leave 12 tons for a vehicle with heat shields and propellant to do an aerobrake at perigee (which for GTO, is as low as LEO), use a skip or recircularization to hit their re-entry target, and land.
12 tons is about double the reasonable estimate of the expendable 3rd stage's dry mass.

Well, i guess it's going to be rewritten several times.
What happened to plans of making the medium-size rocket first?

first week of calculus and i solved all the derivative in my head while everyone else was still busy copying them all down
kek some people are born mathematicians, others have to work hard for it.

Hey guys... I'll start with some basic trig:
When solving something like 2sin θ + 3cos θ= 1
why would using the form rsin(θ+a) be used instead of just squaring all the variables and converting either cos^2 x to 1-sin^2 x or vice versa?
so that it becomes [eqn] 4sin^2 (θ) + 9cos^2 (θ) = 1 [/eqn]
to
[eqn] 4 - 4cos^2 (θ) + 9cos^2 (θ) = 1 [/eqn]
and solve the following for:
[eqn] 5cos^2 (θ) = -3 [/eqn]
I know its wrong... but why wouldn't it work?
thanks.

When you square that you get crossed terms: 6sintcost.

So around 2080? Maybe? If it happens, it happens. Enjoy eternity if you can afford it.

What do you mean? Will ageing be reversed? Will it be slowed/medically controlled? All maybes.
3 years ago mice had their age reversed, but they got cancer and bunch of tumors. If that's any hope for you.

What is it about calculus that just makes it feel so different from learning any other math? The fact that there's a Calc 1-3 shows how much importance it holds. There's a different feeling I get when I'm 19 and have mastered differential Caclulus. There's something different about being skilled at calculus in this day and age.

calculus sucks compared to diffyqs and linear algebra
>>
Calculus is very rote, very applied, and resultantly quite mundane. There's really not much to it. It's pretty intuitive and shallow (as it is taught in schools), and that's why people enjoy learning it. It is something that is perceived by others to be a lot more difficult than it actually is, thus boosting confidence and self esteem.

> stupid questions thread
> pic related
The question asks to find the average distance between oxygen molecules at STP. The solution manual describes a solution that assumes oxygen is an ideal gas. Here's the pickle that my autism doesn't understand.
Are the molecules of an ideal gas not assumed to have negligible volume? I thought the individual molecules were assumed to occupy no space as mere points of masses.
Likewise, does the length shown in the solution actually represent the average distance between molecules--or the length across each molecule?

>Are the molecules of an ideal gas not assumed to have negligible volume? I thought the individual molecules were assumed to occupy no space as mere points of masses.
that's just a piece of voodoo magic for simplification of solution
basically, they imply that each molecule resides inside this cubical volume, and on average, it's located in the middle of a cube.
this way, the average closest distance is equal to length of a cube
>Likewise, does the length shown in the solution actually represent the average distance between molecules--or the length across each molecule?
average distance between molecules, given their volume is null

May I ask my own uber-stupid question here?
Why is it that in every textbooks and online equation solvers do
[eqn]\int tanx dx = -ln |cosx| + C[/eqn]
instead of
[eqn]\int tanx dx = sec^2x + C[/eqn]
?

This whole IQ thing is driving me crazy. I ve been doing several online IQ tests to get gifted level and convinced im smart i went to mensa and got an IQ of 99. Can someone please enlighten me if there is hope? Why do i score a 130 online but seem like a hopeless case when i go to mensa. Is IQ real? does it differ between people? How does being smart feel like ?
Please IQ fags and OP enlighten me.

You really are stupid as fuck if you have to ask a question like this. Two things: 1) Virtually anyone can create an IQ test on the internet that have no real psychological basis. 2) Mensa's own online test is made to fool stupid people into paying for their real test.
>How does being smart feel like ?
It feels like being me.

Why don't we have a political party based around scientifically literate politicians, who's position on the major issues is "will this advance humanity, or will it hinder the advancement of humanity at any level?".
I think the closest we have is, what, the Green Party? I don't think that is good enough.

Because parties based around """"intellectuals"""" tend to be out of touch with ordinary people and thus unelectable.

So all the top dogs in technology have spoken out about not underestimating AI. Or to be wary about it.
What exactly is the problem in just keeping AI on the level of mentally retarded people and using them as physical labor for all eternity?
Please no derailing "it will kill off the lower class" posts. That's not important or the question.
Is it really that hard to keep AI in line?

Not at all.
It is really hard to make well functioning AI of any kind. In fact, it is so difficult to make good AI that it is better to skip the hardware and go right to the wet ware.

Is consciousness an illusion created by complex neural patterns?
Doesn't that mean that supercomputer emulated consciousness would be objectively superior to biological consciousness?

Define 'consciousness'.
Define 'illusion'.
If you dont do this you show dishonesty and unwillingness to facilitate discussion.
>>
>>8340860
Terms only exist as the children of other terms brought into existence by an emulation of instinct so if I were to describe both at the root of their meaning.
Consciousness: Agency.
Illusion: The former is a deception.

What is the part that is watching yourself think. The "you" that knows that is just the same for everyone else. The same feeling of self.
Does that come from the brain?
