I'd settle for finding intelligent life on our own planet first.

Whiteboards, then blackboards. Smartboards? Absolutely not.

I am particularly fond of the Cayley transformation,\begin{align*}C&=(1-Q)(1+Q)^{-1} = (1+Q)^{-1}(1-Q)\\Q&=(1-C)(1+C)^{-1} = (1+C)^{-1}(1-C)\end{align*}where C is an orthogonal matrix and Q is a skew-symmetric matrix. Why? The right hand side commutes. The forward transformation is the...

May I suggest HTTP 418?

Most programs these days are aerospace engineering, which cover both atmospheric and space flight.

It's probably just the basic projectile motion equations.

Looks like X-47B.

This is what our CS department uses for C++ [0]. It's also since been updated to use C++11 and C++14. As a general reference, having a copy of Stroustrup's The C++ Programming Language can't hurt. [0] My claim to fame for this thread is that Stroustrup's office is 3 floors above mine...

No problem, it gave me a reason to dig out my copy of New Foundations for Classical Mechanics and play with that. :D

I'm late to the party, but the problem is you've defined the transfer function incorrectly. N=[1]; D=[1 w]; will produce\frac{1}{s+\omega_0};to get the desired TF of\frac{s}{s+\omega_0}you need to do N=[1 0]; D=[1 w]; The vectors defining the numerator and denominator of the TF...

\newcommand{\a}{\boldsymbol a}\newcommand{\b}{\boldsymbol b} From the original post I'm going to assume the question is answered, so here are the steps to the final solution for anyone interested (noting that I've only done a bit of work with geometric algebra after seeing a talk by David...

Goldstein is good, are are the books by Greenwald. The books by Kane are worth reading as well; Kane's approach to dynamics, while somewhat procedural/methodical, is still useful for arbitrary systems and multibody systems. For a specific look at nonholonomic systems the classic text is by...

I've had good results with Intel and Samsung drives. I've been running an Intel 520 series (or something like that) in my big ThinkPad and a Samsung Evo 840 in my tablet ThinkPad.

Honestly, passwords are horrible and shouldn't be used. Not sure what the best alternative is though...good luck getting people to use PKI properly.
