The peak rate of flow for blood appears to be well under 1 m/s, even in the largest vessels. No, you won't get a noticeable effect.

"How long" isn't the question, but "how fast". You should be accelerating it to a few kilometers/sec, then reversing its velocity when it's a few millimeters from your scalp. You should probably do this in a vacuum, to avoid confounding influences from shockwaves.

No, not spinning, reciprocating -- moving in and out.

You know, like the ones in that Insane Clown Posse song that everyone keeps quoting.

Wow. That's an impressive body of work.

You're on the right track, but I think you'd still be short on power by several orders of magnitude. Even if you strap it directly to your head, your subwoofer's still only good for causing headaches and annoying bystanders.

It's the rate of change of magnetic flux that does the trick. You get changing flux from a changing electrical current, or from a moving magnet. So maybe if you loaded the magnets into a shotgun, then fired them through your brain, you'd notice an effect.

These are magnetic pulses. No, strapping magnets to your wrist/ankle/belly/tinfoil-hat still won't accomplish anything.

This is very interesting, and maybe that's good enough. But isn't there some evidence of what method they might have used? Wood fragments? Tracks? Tools?

I'm asking this as a completely naive onlooker. I'm sure there is research on this spanning hundreds of years; anyone want to provide a quick summary?

This would seem to present a compelling case for buying a telescope on the used market.

Wait, I thought you got double points for those!

I'm intrigued. This project seems like a more engaging and worthwhile use of my time than the crowdsourced editing of Slashdot summaries.

Take a quick look at the Wikipedia entry for stenotype to see why using a stenographic keyboard for coding is such a laughable idea.

Stenography relies heavily on a highly-trained stenographer to do the recording, and on a similarly highly-trained individual to turn the record into recognizable English. Trying to use that for writing code, where you don't have the redundancy and patterns of English, is a bit like trying to use Swype to transcribe telephone numbers. Wrong tool for the task, period.

...you obviously haven't been hanging around here for long.

Interesting, and thanks for posting this.

Apologies for the uninteresting followup, posted to remove an accidental down-moderation. I suppose it would be too much to hope that the next version of Slashdot will not let you mis-moderate simply by releasing the mouse when it's one pixel off from the intended target.
