Comment: won't this zero out? (Score 1) 201

the vacuum is electrically neutral; the virtual charged particles
created by quantum fluctuations will be in oppositely charged
pairs (e.g. electron / positron). Won't this drive send these pairs
in opposite directions? So the whole thing will have zero thrust

this thought is the product of complete ignorance of how this
drive is actually supposed to work however :)

Libel/slander laws do not limit speech. They can only be applied after the fact. So you can be held responsible for what you say or write, but you cannot be restrained from saying it in the first place.

This doesn't make sense. Laws forbid you to utter slanderous statements. Other laws forbid you to utter "fire" in a theatre. In both cases, I can commit the offense. So either slander laws *do* limit speech or the "don't shout fire in a theatre" does *not* limit free speech. Which is it?

The point is that either you have reasonable basic liberties, or you don't. If you think an adult ought to be able to decide what they will or will not ingest, then how do you get from there to the authorities stepping into that decision using coercion? If you don't think an adult ought to be able to make those decisions for themselves, then I can't have a meaningful conversation with you.

I think you mean an adult can ingest anything he wants so long as it does not harm
others (suppose I ingest substance A and B which together form a powerful explosive,
right beside YOU. Do I have the right to ingest A and B. I think not).

Now, we should have a *meaningful* discussion of whether **some** drugs are such
that there consumption harms others to a sufficient degree to warrant prohibiting their
ingestion.

I think it is completely obvious that marijuana poses no such risk; not so sure
about crack cocaine (and, from another angle, potential cognitive enhancers,
steroids for athletes etc.)

there are two papers: the Van-Gheem et.al. paper you cite and then there is the
one the slashdot article is about, which is:

Use of laptop computers connected to internet through Wi-Fi decreases human sperm motility and increases sperm DNA fragmentation. by Avendaño C, Mata A, Sanchez Sarmiento CA, Doncel GF.

The authors are the Argentineans which the linked article mentions.

It's (to be) published in Fertility and Sterility.

So I basically don't know what you're going on about ...
