It's been a long time since I've seen a reference to Shepard tones. I used this, along with another (novel) auditory illusion, as the basis of an auralization technique to complement visualization of computational fluid dynamics data, which became my dissertation research.
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
In "A Universe from Nothing", Lawrence Krauss posits that the negative energy associated with gravity can exactly cancel the positive energy of the rest mass of all the particles plus their kinetic energy.
What state do you live in?
Thanks for all the replies, folks. That's fascinating.
Ugh. I forgot to log in first before posting that. I was wondering why I suddenly had to pass a captcha test.
is performed by the complex circuitry of neurons in the retina.
Really? Not in the visual cortex of the brain? It's actually done in the retina itself?
I You get changing flux from a changing electrical current, or from a moving magnet.
How about (iron-rich) blood *moving* past a stationary magnet?
There are less than 2^33 people in the world. Most of them probablly don't use google but lets assume that they do. Further lets make a wild ass guess that each one has 2^17 files in googles database (from some googling i'm pretty sure this is an overestimate). That would mean a total of 2^40 files.
Check your arithmetic.
Can a single photon turn into an electron/positron pair? I didn't think this was possible because a photon has no rest frame, whereas an e-/p+ pair always would. Thus, in the inertial frame in which the pair has no momentum (the "center of momentum" frame), the photon would still have momentum. Thus, momentum would not be conserved. You need two photons moving in different directions for the pair of photons to have a center-of-momentum frame in which their momenta cancel each other out.
"Music and film" is too restrictive. I prefer "Multiple Art Form Industry Association of America". Same acronym.
This was the plot of an episode of The Partridge Family (except for the jail part). Shirley eventually solved the problem by mailing the collector a check for $0.00.
That's the stupidest thing I've read all year.
Statistics. That unforgiving bitch no one asked to be invited that tries to manipulate all of our lives.
Statistics don't manipulate people - people manipulate people.
I'm the ASA. And I vote.
I'm glad my beloved grandfather and great uncles are gone, they fought against fascism in WWII and this kind of gestapo shit would disgust the hell out of them. I could probably wrap his body in some copper wire and run my entire neighborhood from all the revolutions he's turning in his grave.
I wish I had a chance to know your beloved grandfather and great uncles. You know, back when they were walking magnets.
If you pay for something and they don't deliver, can't you just call your credit card company and dispute the charge?
