  1. All theories are constantly evolving, that's why scientists don't think of them as absolute truths or laws. Thinking of them like this keeps their mind open to change. This is the fundamental difference between science and religion. It actually appears to be 20m/s and conduction time over 2.5cm cochlear nerve length is 1.25ms. That equates to a maximum possible firing rate of 800 impulses/second, although I'm sure there will be a short latency for recharging making it a bit less ...likely the 600 I mentioned earlier.
  2. Here's a couple of interesting bits that support what's been said: Temporal Theory (hearing) Volley Theory N.B. A 'theory' in science is the best you'll ever get.
  3. Yes, but you can see the principle? That's right.
  4. No, it doesn't matter how long the 'information' (within reason) - which is the 1000 leaves - is carried to the bin by 1000 snails. There are 29 000 snails waiting for for next load of leaves.
  5. No criticism was inferred. There is a specific aspect that the OP is trying to grasp and I'm trying to help him zone in on that. How the information is coming and how it's captured.
  6. Where does the planet end and nature begin?
  7. ms is millisecond. I would suggest you stick to learning human hearing first, and diregard other animals, otherwise you might be comparing apples to oranges and mess your learning up. The problem is that the 'bottles' going into the ear canal aren't backing up, they are being taken as fast as they arrive because there is always a nerve cell - out of the 30 000 - waiting to fire.; that's where the staggered microphone analogy comes in.
  8. It can be more fruitful sometimes to consider that there is no thing in the universe that is absolutely stationary that one can measure everything else against; it must always be relative to some arbitrary reference. If you are sitting on a small rock in space with nothing else around you, how fast are you going? If you are moving in a straight line with a constant speed you will consider yourself stationary.
  9. Yeah I learnt something too about the history. Obvious, in retrospect, really when you think about it why they were called 'Brussels' innit? Just a happy accident as well.
  10. On the subject of Brussels: see if you can glean anything useful from this article by the UKs Royal Horticultural Society.
  11. The more acidic, the better for me. The sweetness should be a minor counterpoint to the acidity. I love acid-tasting things.
  12. How is it not a pudding? You put custard on it. The trick is to balance the amount of sugar with the acidity in the rhubarb to your taste.
  13. I think this analogy illustrates rhe resolution issue nicely and was trying to think last night how to express it; to no avail. Interesting subject.
  14. I look forward to it. Here's that article.
  15. This might seem counter-intuitive, but the faster something is sampled the slower it will seem, subjectively, compared to something that has a lower sample rate. Think about when you are in a fearful situation, everything seems to slow down, because your senses and brain are processing faster.
  16. Yes it will sound the same, but the sound will reach him four times faster. To illustrate this: if the underwater speaker sends a series of short single-frequency pulses, one second apart, the first pulse would reach hime FOUR TIMES quicker than in air BUT the rate of the pulses will STILL be one pulse per second. No, because the received oscillations will still be a 1000 cycles PER SECOND, regardless of the transmission speed of a nerve. Kilohertz is frequency over time, and time or frequency does not change just because the medium, sample rate or nerve transmission speed does.
  17. Something cannot come from nothing, hence, it was always thus.
  18. I think this is not correct. The cochlear is the exact equivalent of the retina. Think of the sum total of vibrational perturbations in the cochlear-fluid in any instant in time - this is the aural 'picture'. All the cilia register information about those perturbations in concert with each other simultaneously. The speed of sound is 4 times (1500 metres/second) in a fluid than it is in air, so it can propagate and be registered faster at the cilia than it is coming in.from outside the cochlear. Propagation of Sound in Fluids. (PDF download) . Density of the medium the wave is travelling through.
  19. If I have seen further, it is because I have stood upon the shoulders of giants. - Newton. He didn't just make stuff up from nothing, he built upon existing ideas. Your idea doesn't do this.
  20. Even if you could the driver would have to be made of photons too, otherwise his mass will constrain the maximum speed.
  21. I don't know the rate of fission at critical but in the Little Boy bomb each piece was 2/3 critical which brought it to super critical..
  22. I wondered how many adjacent sun-sized stars might span the diameter of a 50 000LYR galaxy and I got 339 057 572 254 suns. No wonder we can't see them individually in the halo in a picture.
