No one can really argue that recreated intellegience as it is in humans, in computers, would be extremely difficult.
I had an idea - there was this Miller-Urey experiment conducted in 1953 -
http://en.wikipedia.org/wiki/Miller-Urey_experiment
where these scientists successfully created organic molecules from inorganic molecules in a primordial-earth-like chamber.
I was thinking, what if you somehow make this supersuper computer that could would keep track of every atom / subatomic particle in a virtual miniworld. Then run the same Miller-Urey experiment, but virtually. This time however, make the computer simulation speed it up as much as possible, and have it run till (hypothetically) it would create living organisms. Eventually organisms with brains and the such would form. Once you get some form of intellegience in this virtual world, all you have to do is copy their atomic code onto another computer, and there you'll have AI. What do you think?

Last summer, my wife and I witnessed unusual lightning during a midwest thunderstorm. It was gold in color compared to the normal white/blue light we'd expect to see. It was also extremely slow in how it struck. We could actually witness it start from the ground (or close to the ground) and culminate in the clouds -- much slower in its development than a normal lightning bolt. The path wasn't very straight, either. However, it was almost smooth in the various twists and turns, rather than jagged.

There was a significant amount in close area and short amount of time. We must have seen a dozen strikes in a very short time, all with these attributes.

I've searched, and can't find anything close to what we saw.

Any ideas? Thanks!

I am currently taking AP Physics and AP Calculus. So far AP Physics B(without calculus) is easy I have an A. However AP Calculus AB I have a B in there. Is physics with calculus in college a combination of the two, say using integrals from calculus and momentum from physics or something similar?
