we're just one stage removed from animals and we're still trying to throw off our bestial nature.I agree - most human problems are internal, at their basis.
We've invented ... science and a host of other things that make us more civilisedThe real explosion since Galileo has been in the "hard" sciences - physics, astronomy, chemistry, geology, medicine, imaging, mechanical, civil, electrical and aerospace engineering, etc. This has been assisted (and enabled, in many cases) by rapid developments in computing.
What I would like to know is what would ACTUALLY happen if you had a thimble's worth of Neutron Star material here.Leaving aside the minor difficulties of mining a thimble of neutron star stuff, lifting it off the star against enormous gravity and safely transporting it to a soft landing on Earth....
s = 0.5 a t^2 where s = distance, a = acceleration and t = time (you did that at school, surely?)
Minimum transit distance is probably 10^11 meters. Put a = 20 m/s^2 (a bit more than 2g) then t^2 = 10^10 so t = 10^5 seconds, just over a day.
[The glass] was to be perfectly flat. However during the heating phase, it was heated unevenly and it became parabolic.Early telescope mirrors were cast as a flat disk, with some blocks in the back that are removed later to make the mirror lighter.
Almost all that are familiar with the crazy weapons and prototypes at aerospace plants understand the parabolic effect.In 1970, one crazed man went berserk, using a 9mm pistol and hammer as weapons in an attempt to destroy the primary parabolic mirror of the McDonald telescope.
Got to start somewhere. If even 10 people reply and all of them have masturbated safely in this position then there is evidence to suggest that it is not inevitably dangerous.
As with any type of radiation, microwave EM radiation drops off with the square of distance.This is true of "far-field" electromagnetic radiation which has been emitted by the device and will propagate away to infinity (if it isn't absorbed by someone standing too close).
The glass window prevents you for getting too close to the holes where the field is slightly stronger.
