  1. You can probably make a room shake by sheer volume, without resonance. If you can download a "chirp" (a varying frequency from say....20 Hz to 200 Hz), to a disk, and assuming you have a speaker (or other transducer) that will recreate the frequency, you could do some experimenting. If you play the chirp, and if anything is is self resonant, and depending on the Q of the circuit, you'll get a large peak at the resonant frequency, not in volume, but in the vibration. But be careful, if it's a series resonant circuit, with infinite Q, you may bring down the entire house.
  2. I guess most minds can't picture it, but for the mind that can visualize it, probably understands it. Maybe the holes are real and imaginary....like impedances.
  3. I've never watched "west wing"......but I guess I can understand a moderate pro-choice Republican getting the lead role on the ticket, but I seriously doubt you'd ever see a pro-life Democrat on a ticket. After all, Kerry had to announce he was a pro partial birth abortionist to secure his far left base.
  4. As John said, it's the irony. If an oil tanker had accidentally hit the reef, Green Peace would have ripped them to shreds and demanded a 10 million dollar fine.
  5. Why wouldn't it be nationalistic, since the Americans were in a race with the USSR ?
  6. I AGREE IMO, A country without citizenry patriotism is vulnerable from "within" or "outside". And IMO, impartiality, or in some cases aversion and antipathy can lead to defeatism, capitulation and/or fleeing.
  7. On the political spectrum, CNN is left, and FOX is right. Do we need to go to Aljazeera ?
  8. Wouldn't it be better to compress the rubbish into little singularities about the size of a pea?
  9. I can understand the confusion. Sound waves must travel through a medium. Electromagnetic waves can travel through a vacumn. the power lines (U.S.) operate at 60 Hz and are electromagnetic waves, however, it you attach a speaker to them, you can convert them to sound waves.
  10. Talking about selective breeding, A decade or two ago, Jimmy "the Greek" Snyder, former TV football color man, was fired and severely castigated for his comments on how Blacks were better athletes that whites, because in the slave days the white owners specifically bred the big strong males with the big strong females.
  11. That's a big fella, cute too. I wonder if Ms Hominid Lucy had one for a pet.
  12. Good post Mokele, but I'd put "environment" at about 5% on the list of reasons why Blacks are better at certain sports.
  13. But you'd have to program it so it knows what to learn, and you don't know what it should know what to learn.
  14. I stand corrected Ecoli.........'chewing on humble pie.'
  15. Bettina and Eon_rider Yeah, it's interesting, visualization is the key to understanding.
  16. What we *do* know, is that every terrorist act against the U.S., from Pan Am/Lockerbie to the world trade center was commited by Islamic peope.
  17. I had read once that Einstein was not much of a mathematician, but he had a unique ability to visualize, he could visualize what would happen if he was riding a beam of light. When I'm doing a calculation (engineering), I find it important to be able to visualize the answer.
  18. C'mon Pangloss, you know better than to ask that.......
  19. That's probably true, but for every black in the urban areas, there's 8 or 9 whites from indiana practicing just as hard. And if only 1 of those 8 or 9 whites make a team, that would make the basketball team 50/50. But on some teams, it 100/0. Hey, Larry Bird was great, only because he had eyes in the back of his head, but Doctor J. floated through the air like a butterfly....what a player.
  20. Of course they do. they're also the best long (marathon) and short distances runners in the world. IMO, it's genetic. Given that Blacks are roughly 13% of the population, and given that whites practice (and like) basketball as much as blacks, the odds of fielding an all Black starting 5 basketball team are astronomical.....unless they're better than whites.
  21. Yeah Bettina, given that some of the radical Islamists want to rid the world of all infidels, there's cause to be concerned.
