Take the average debate on TV about the Iraq War (now with Syria and Iran) and it looks like, Should we bomb them now or later? The debate has been framed; excluded are the ideas of not bombing Iraq at all, or removing our military bases from all around the world, or diplomacy, or or or Same, too, it seems to me happens in the world of science. Therefore, How would you interface with the screen? Another interesting point to consider is that in addition to acting like a resistor, the epidermis acts like a capacitor if placed in contact with a piece of metal (the underlying tissue is like one plate of a capacitor and the metal surface is like the other plate - the dry epidermis is the less-conductive material or "dielectric" in between) .
