Any aerospace engineers on /sci/?

What do professionals praise more - AIRBUS or BOEING?

As an aircraft mechanic, I find it somewhat frustrating that Airbus insists on using both metric and imperial measurements on their aircraft.

call me a brit-bong,
But i absolutely hate the inperial units
I feel SI units are the real and only way to go

>>7807004
>>7807007

Of course. SI units were created to unify measurements on international projects. Imperial has no place outside very specific local projects (and even then it's not the ideal choice)

If the ans D. Then the bottom 2 shapes in columns 1 & 2 appear to be mirror/transform/reversal (reversal meaning concave to convex).

it really is E.
but what's up with the other pictures then? where's the pattern there?

sci, how can I find x in this equation? e=x^(x) pic unrelated
>>
>you dont
>>
x^x = e^(log(x^x)) = e^(x·log(x))

=>

log(x) == 1/x

and now you gotta check the productlog
>>
why don't you just see where x^x=e in a graph?

Why is $H_{3}O^{+} + HO^{-} \rightarrow 2H_{2}O$ and not $H_{4}O_{2}$?

Bcus energy and entropy and shit.

Basically it's not a stable molecule.

>>7806781
Thermodynamics basically says what atoms click together easiest. Just because the numbers of atoms add up, doesn't mean it's a low/stable energy state.

what's your degree and major /sci/?

Question:
Is convergence in probability

${ plim }_{ n \to \infty } X_n = X$

formally given by

$\forall( \varepsilon > 0).\ \lim_{n \to \infty } Pr \left (d(X_n, X) \geq \varepsilon \right) = 0$

?

And does anyone know Hairers work? I only read one of his paper last year when he got the price, and I get the gist of it - he does a sort of Tailor expansions for super non-smooth objects.
Anyone here working with that?

Why are overdeterminate systems of linear equations always have no solutions?

>>7806680
TM™
>>
>>7806680
you are wrong.
x+y=0
2x+2y=0
3x+3y=0
this overdeterminate system has an infinite number of solutions.
>>
>>7806687
It's not overderminate since the equations are linear dependent.

Well /sci/ I think it's time we talk about the near future of energy. Is CCS worth putting effort into or is it just another scientific brag from the fossile fuels department. Discuss and be friendly.

What ever it is we are talking about, is likely patented or banned. So it's not going to happen.

I read an article on this. So they did a study and determined all of the geoengineering schemes proposed to deal with global warming would be hideously expensive and be totally worthless or would actually make the climate worse. Like irrigating the deserts to create forests on them to sequester carbon could cause the oceans to die and other areas of the world to turn to desert, because there is no more dust being blown off the desert and into the oceans for micro-nutrients and air to form raindrops.

The conclusion was only halting carbon emissions entirely would avert...
