are not we "banging" our "sisters and brothers" ??
wtf is that ??
are they stupid or something

I once asked a biologist if it were possible for a species to propagate from just two members (male & female). She said that there was a mathematical proof that showed it is possible to create a viable gene pool in a finite number of generations, despite the incest. You end up with a lot of $#%^#ed up people/animals/specimins along the way, but if they don't breed, you get a viable gene pool with enough diversity that the recombiant recessive genes are not an issue. In other words, wait enough generations, keep the messed up specimins from breeding, and eventually you have enough genetic diversity that the people are genetically not like "brothers and sisters," despite common ancestry.

Now I'm a scientific type of person myself. And I have created mathematical proof of the existence of the _immaterial_* soul. For this I had to assume free will - that is that it is not given nor random what I will do in the next moment. "I have choice" implies "I have a soul". If you're interested, I can try explaining the process of implication here :). It's probably gonna be long in text...
*immaterial - not immortal. That I do not know and cannot know, therefore a quantum superposition of states as in the Shroedingers cat theoretical experiment.
Jack2000:
free will...
the free will is the natural *next step* in evolution
there is nothing supernatural to it...

This has been know about for hell of a long time and is what happens in radio wave propagation, it's a long time since I did this so here goes:
With a 1/2 wave dipole antenna:
An E-field (electric field) solely exists near the aerial then further away (1/2 wave length I think) it's matched by an equal H-field (magnetic field) at 90 degrees to it.
The reverse is true with a 1/2 wave folded dipole.
An H-field (magnetic) solely exists near the aerial then further away (if I'm right 1/2 wavelength again) it's matched by an equal E-field.
This only applies to alternating electric and magnetic fields, which consist of both electric and magnetic fields. A steady state E-field (for example (a balloon with a static charge on it) or an H-field (like an electro magnet) always remains the same since its wavelength is infinite.

Umm, NO. Radio/light wave propagation is something completely different than what I was talking about, and the statement that a steady-state E or H-field never changes is just plain wrong. It changes with the velocity of the frame of reference.
A steady state E-Field looks like a combination of an E-Field and an H-Field from another velocity. Likewise a steady state H-Field at one velocity looks like a combination of a steady state E-Field and H-Field at another velocity. This is because E and H fields are not really separate entities, but are physical manefestations of one tensor quantity: the electromagnetic field tensor. The parts of the field tensor you "see" depend on your frame of reference.
So your statically charged balloon? It looks like it is emitting a magnetic field as well as an electric field if you are looking at it while travelling at relativistic speeds with respect to the balloon. Likewise, your magnet has a static electric field under the same conditions. It's wierd. That's relativity.
Look at the nutshell version from Wikipedia. It really doesn't go into enough information about relativisitic tensor transformations, but it's a start.
