Is it possible for us to estimate the time of our next evolutionary upgrade?

Would it occur at birth (like most of the X-men mutants), or would our bodies and/or minds suddenly go under drastic, phenomenal changes? Would those changes happen to every human at once, or would they be more likely to happen to certain individuals?

Can we predict what kind of changes might happen to us? Have we discovered an evolutionary pattern or something that could give us an idea what changes might be to our species? -- such as perception, fears, etc. of the subconscience or major events of the stimuli?

Also, what would happen to the rest of the species on the planet; do they have their own evolutionary cycle. If so, how have they evolved (if there are any periods recent enough)?

Where are we at?

If the design of an inductor calls for 80 turns of .5mm wire around a 40mm OD iron torroidal core, how do I calculate the inductance in mH or uH?

This isn't a homework problem, I'm building a circuit that calls for this inductor and I want to know what the resulting inductance is so that I don't have to build the inductor myself. I want to purchase one pre-wound.

It drops into a ramp of height h.
The ramp forms a trough that guides the ball upward at an angle of theta with respect to the horizontal. At height n, the ramp ends.
At a distance d, there is a landing pad.

If the landing pad is positioned at exactly the right position so that the ball is only traveling horizontally, what is the height of the landing pad above the end of the ramp (a)?

Here's a picture

Calculate the height if h=4m,n=2m amd theta =45 degrees
use the 9.81m/s^2 for gravity.

i need to know the chemical names of [Cr(H2O)6]Br2 and [CoCl(NH3)5]SO4 and the chemical formula for tris(1,3-diaminopropane)chromium(III) chloride also if you know the structures of the complex [Ru(NH3)3Cl3 or [Co(en)2(NO2)2]+ any of these answers would help out a great deal

I've heard that 7018 rods should be used within 4 hours of opening. I have a tube that has been opened for longer than that and probably exposed to the atmosphere for longer. I don't have a rod oven, but my "home oven" goes up to 500 degrees and I've read that 500 degrees for an hour will do the trick. I am concerned about fumes from the flux, but other than that I see no reason why I should not be able to "rebake" these rods in my home oven.

Please list any sources you find or know of.

Thanks for your help in advance!
