imagine a flexible strip to rise things into space. Why can´t we do so? Where is the thin spot? Why the force of gravity doesn´t let us to hang things from orbit and such avoid the burning derived from accelerating through the atmosphere, and once in just drop the things with a parachute?

Do you just go out there and do it a few times before you get over this? I'd like to be on Animal Planet when I grow up.

Using the simple formula ( x - y )^2 = x^2 + y^2 - 2*x*y
I have proved that 2 = 4

Here is the proof:-
-8 = -8
4-12 = 16-24 (since 4-12= -8 & 16 –24 = -8)

Now add 9 to both sides
4 – 12 + 9 = 16 – 24 + 9
2*2 - 2*2*3 + 3*3 = 4*4 – 2*4*3 + 3*3
2^2 - 2*2*3 + 3^2 = 4^2 – 2*4*3 + 3^2
this steplooks like the formula x2 + y2 - 2*x*y = ( x - y )2

( 2 – 3 )^2 = ( 4 – 3 )^2
So 2 – 3= 4 – 3
Add 3 to both sides
2 = 4

try to find the mistake in this

When a bird dies naturally in the wild does it sit on a tree limb then die, falling to the ground? Does it die while in flight? And oddly enogh with as many birds as there are I just don't see their equivalent ever lying around dead? I know animals carry off many but that many?

Is there by any chance something analogous to a ratio test, but for covariance matrices instead of variances? I know how to use the F-test for variances, but I would like to compare covariance matrices to see what I can learn about goodness of fit for nonlinear regression, looking at fits using different numbers of parameters (in this case, summing different numbers of exponentials to get my fit function).
