Comment Re:a microscopic black hole won't hurt you (Score 1) 148

Are you sure? ISTM that it would initially prefer either electrons or protons, and when it had swallowed a couple of them it would repell any more. (Electrons are smaller, so it might prefer them, but they are also more uncertain as to their position, so it might prefer a proton.)

So say it swallowed an iron nucleus. This would give it a strong positive charge, so it would repell any additional nucleus. The question is could it also swallow electrons, or would they go into orbit around it?

*My* guess says that it would need to be sufficiently larger that gravitational effects would dominate over electromagnetic effects. OTOH, since 6 picometers is around 1000 times the size of an iron nucleus perhaps I'm overestimating the problem. That said, what's going to slow it down? This is an accelerator, so even if it created something with the mass of Mt. Everest, it wouldn't be at rest, and would, in fact, be moving far above escape velocity.

Comment Re:View from a patent holder ... (Score 1) 87

Given how bad many issued patents are, I feel that it's the presumption of validity that is the mistake. And that the baby being thrown out is a baby predator...which we would be vastly better off if it were killed.

There actually *is* a good case to be made for certain patents, but for such a small percentage that with the current system even eliminating all patents would be a net gain.

Comment Re:Creationism (Score 1) 445

Sorry, but you fall afoul of the problem of "What constitutes reasonable proof?" This is a serious problem, as if we are Bayesian reasoners, then what consititues reasonable proof is highly sensitive to our priors. It is also provable that for certain sets of priors there is *NO* evidence that could possibly switch one from one set of beliefs to the other.

You outline what you are currently considering a set of proofs, but that means that you think they would suffice to convince anyone. This is not true. And "Creationist" is not a single set of priors, but rather several such sets, so even if an argument would suffice to convince one particular "Creationist" it might well fail on others. Now flip this around. Would you really change your opinions if they produced what they considered was good evidence? I truly doubt that. You are just certain that they can't produce what *YOU* consider good evidence. But be aware that you, also, cannot produce what they consider as good evidence.

What we call "reality" isn't what we sense, it's what we believe about what we sense. And that's all the reality we can ever know. And this is mathematically provable if you assume that we are Bayesian reasoners. (It's probably true anyway, but you can't prove it without the assumption.)

Sargon was significant as the tale of Noah and the flood was an edited steal from Babylonian myth...and they (probably) got it from the Sumerians. (IIRC, Sargon was also found floating in a small boat by a princess, like Moses...but I suspect the Moses story came from Egypt rather than from Akkad.)

Higher energy photons are distinct from lower energy photons in having a shorter wavelength. They both travel at (about) the same speed. Presumably in a true vacum they would travel at exactly the same speed.

Thus blue light is more energetic than red light, and has a shorter wave length. You measure the energy of the photons by absorbing a certain number and measuring the change in velocity or temperature of the thing that absorbed them. (Usually this is done by some sort of photocell arrangement were the absorbtion translates into electron volts, and that's what you actually measure. I believe that this has been done down to the single photon level, but I'm not sure.)

Comment To the editors (Score 4, Interesting) 53

If you are going to have a story like this it would be good form to remember the H, aka HOW from who,what,when,where, why and HOW of a journalism article. At some point in the past this was a site oriented to the technical community, most of whom are very interested in the how. You might even think that for the most part the when, why, where and who are all at the who cares level. (Mars being an exception)
