Oh snap, thanks.

If I know the gradient of a function of two variables how do I find the direction of the level curves for any value of x,y?

I know that the level curves must be perpendicular to the gradient, but how can I find a vector perpendicular to the gradient if the gradient is given?

Evolution doesn't happen the way you are implying it does on those kinds of time scales.

You should also read The Man In The High Castle and Valis.

and I think the term is the Planck Time

There's work in consultation outside academia, but not all that much else.

You're doing that right now.

Serious answer, you can take advantage of relativistic effects to slow the passage of time for yourself.

Backwards time travel is impossible without a stable wormhole, and good luck making one of those without negative-mass matter.

>Corporations only cut corners that don't matter or nobody notices (which means they don't matter), that doesn't even apply to this.
>Privatization is good because people trying to make money would come up with the most efficient methods of education so they could get more customers.

Blatantly false. It's like I'm on /pol/ where everyone professes the highest regard for Chicago economics but nobody seems to have actually studied it. In instances where the product being provided has a positive public impact that is not compensated for, you get an externality that causes the market to underproduce. Private schools would only ever meet the market demand for education, but not the social demand (a difference that matter when you're competing in a global marketplace). In these instances, it is more efficient for the service to be provided by the government. This bullshit about liberal brainwashing is unsupported conspiracy theory nonsense.

Then why haven't you done it yet?

Progressive rock, early post-rock, post-punk, post-hardcore, shoegaze, noise rock, some romantic and some modern classical.

So free will is the sensation of free will?

What impact do you think this hydrocarbon fuel-from-air thing will have if it can be done on an industrial scale?

I love this idea, but electronic components, at least the ones that don't require any rare elements, won't be that difficult to print as the technology advances.
