  1. Oh sure, I guess, I thought I covered that in the first part; a static loss of volume can be overcome, but the dynamic losses cannot The example I gave had only about 3dB of loss, but JBL has measured on average 6dB in large powered systems; there is more than thermal dynamic compression going on, there's also thermal bl compression et al. Partygoers may not be a good example, in that they probably aren't listening for dynamic losses. In fact, I would bet $100 that many people, listening to their low sensitivity system, are unaware of the dynamic losses that are happening. I'd also bet that these same people lament the 'loudness wars' trend of dynamic compression of music and are unaware that their system is responsible for 'built in' compression
  2. That would recover the SPL (until the voice coil adhesive melted), but the dynamic thermal compression would get worse and worse
  3. Discovery, 2000,JAN People who live in developing countries often have parasitic worms in their intestines. On the other hand, they rarely get inflammatory bowel diseases such as ulcerative colitis. Immunoparasitologist Joel Weinstock of the University of Iowa suspected a connection, so he asked six patients with these diseases to quaff a brew of worm eggs. Five of the six went into complete remission within three weeks and stayed symptom‑free for up to five months. The sixth patient, who already had permanent bowel damage, improved significantly. Animal studies suggest the worms modulate an aspect of the body's immune system called the Thi response, which can mistakenly attack healthy tissue. The worms seem to suppress Thi and enhance the related Th2 response, creating a better environment for them‑and for the host. "For all of our existence these parasites have been with us. They need us, and we need them," Weinstock says. He believes the absence of the worms in affluent persons' guts could influence diseases such as multiple sclerosis and rheumatoid arthritis.

  4. That's a different kind of flat than the flat earthers are talking about
  5. Here's the first companion piece. If you've been following super-symmetry/string theory/m-theory (I've been following it since I was a kid, talking with Physicists at Brookhaven national lab in Long Island in the 70's) then much of this will be a refresher; still, they way it's presented is very nice
  6. Nice; looks like they share many ideas with Earle Geddes ? http://www.gedlee.com/Lo Fantastic radiation pattern
  7. The on screen talent looks and sounds like a yoga guru, but the text is about the friendliest to the casual observer that I've heard.
  8. Steve's a very soft spoken guy, that's for sure. It would have been nice if he gave a couple of examples though: Consider two loudspeaker systems with 8Ω nominal impedance and copper voice coils A has a speaker efficiency of roughly 0.4% (99.8% of incoming energy is wasted as heat) B has a speaker efficiency of roughly 2% (98% of incoming energy is wasted as heat) In the case of a static signal (e.g. 1Khz sinusoidal at a steady amplitude) yes, you can bump the volume of speaker A to match level with speaker B In a dynamic case (music), however, things change a bit. First ..... Higher sensitivity means less thermal compression, always In the case of dynamics, therefore, the higher sensitivity speaker will always be superior (JBL has measured the average thermal compression of a high power loudspeaker system to range between 5 and 7 dB)
  9. Right on! That's a perfect example. It's more likely that any given individual will attempt to incorporate an unfamiliar phenomenon into their experience by trying to fit that phenomenon into their existing framework, rather than do the work of comprehending the principles behind the phenomenon (which would expand their existing framework). The square peg approach, and it often is incomplete. In your example above the Astronomer and the Animator are both gifted; the Astronomer realizes an esoteric aspect of what is being modeled that the Animator is probably ignorant of. If you think of the transaction as a conservation of momentum at very high velocity, it becomes more clear that the conversion of the falling mass into kinetic energy will have a spherical wavefront, except at extreme grazing angles That's always a danger when trying to understand something with incomplete information
    My favorite Douglas Adams moment
  10. Yes. As atmosphere gets thinner, a rocket engine's thrust plume spreads wider and vertical force is diminished. Some SSTO (single stage to orbit) vehicles get around this, and the aerospike engine can continuously vary it's plume shape. Back then the Rockets had to be staged. one nozzle shape for higher atmospheric pressures, another for vacuum and a couple for in between
  11. Some of my favorite things contradict 'common' knowledge. e.g. if you remember from school that the angle of incidence equals the angle of reflection, then you might think otherwise..........

  15. Lyrics: And the angel of the lord came unto me Snatching me up from my place of slumber And took me on high and higher still Until we moved to the spaces betwixt the air itself And he brought me into a vast farmlands of our own Midwest And as we descended cries of impending doom rose from the soil One thousand nay a million voices full of fear And terror possessed me then And I begged Angel of the Lord what are these tortured screams? And the angel said unto me These are the cries of the carrots, the cries of the carrots! You see, Reverend Maynard Tomorrow is harvest day and to them it is the holocaust And I sprang from my slumber drenched in sweat Like the tears of one million terrified brothers and roared "Hear me now, I have seen the light! They have a consciousness, they have a life, they have a soul! Damn you! Let the rabbits wear glasses! Save our brothers! Can I get an amen? Can I get a hallelujah? Thank you Jesus This is necessary This is necessary Life feeds on life feeds on life feeds on life feeds on This is necessary This is necessary Life feeds on life feeds on life feeds on life This is necessary This is necessary Life feeds on life feeds on life feeds on life feeds on This is necessary This is necessary Life feeds on life feeds on life feeds on life
  16. Lyrics Thanks a lot, thanks a whole lot. Lulu sends her friends They cover the mouths with one hand Well, I keep waiting here Drifting around in a dark land Envelope unturned « I push the stamp and stick it » Chorus: And I know there's a bell to crack And I know there's a bell to crack Well, I hear crosstalk now Coming through the wire One voice tells me yes The other is a liar Chorus: And I know there's a bell to crack I know there's gotta be one more bell to crack « Click-clack, joint, » this thing is on my sleeve All this mess around and I gotta clean it up Okay, Mister Questions, you tell me, when are we gonna leave? And can you design a heart??a heart that doesn't bleed? Chorus: I know there's gotta be one more bell to crack I know there's gotta be one more bell to crack See the bell, so I crack it You just can't find good bells anymore! Yah! Yah! Sure! Tom Shane's a friend of mine! I really like him??he's in the industry! I know there's gotta be one more bell to crack I know there's gotta be one more bell to crack
