  1. Alright, if someone else has had it now and then that's enough to assure me, I just wanted to be certain, no harm in that. I've never had a fully sleeping limb before, only partly. And I actually thought it's due to decreased blood flow, so I thought it might be something with my blood pressure. It's apparently to do with the nerves, though, not with blood vessels. In this case, pressure on the nerves.

    Shadow Optics

    http://www.backgroundscity.net/data/detailthum/4/clouds%20In%20Jamaica.jpg Look carefully. Why is there a "shadow" of this cloud visible?
  3. Everyone's had sleeping limbs, but is it normal if you're completely unable to move or feel a sleeping arm for a full minute? When I got up this morning, for a while it felt as if my forearm felt like it was a plastic attachment to the rest of my body. I shook it, trying to revive it, but for a while it dangled limply from my elbow. It was quite a frightening feeling. Later that day, my fingertips went completely numb due to cold — again, it's normally quite normal, but this time the numbness was complete. What could this signify? I'd been sleeping on my arm, but I'd assume it's still not normal even in that case.
  4. Sorry, I meant "I'm assuming it isn't coincidental" which would have sounded more appropriate. Yes, it can be coincidental, of course, and now you remind me of all the other things that are coincidental, there's really no telling whether it's coincidence or not. Still, even though there are a lot of properties associated with planets, there aren't many that vary in frequency (angular frequency in this case). I remain open to the possibility that there's some abstruse mathematical explanation. Could it have something to do with the hydrodynamics of the proplanetary disc? Obviously, if it's not coincidence, then it must have been caused by some kind of interaction of other, and the only I could think of are gravity and, perhaps, hydrodynamics. Unlike gas, dust does not behave like a fluid, but seeing how gas predominated in the proplyd I would assume it would not distort the hydrodynamics much, at least if the proplyd was dense enough? Was the proplyd at any time dense enough for collisions between the particles to have caused significant mechanical effects? The gas and dust probably already moved in an ellips. Is it possible that the density would have increased at aphelion? I don't want to be associated with Kepler's flights of fancy, though. I'm an agnost, and religion has no relevance here. I just think there could be some mathematics behind it which we can't see yet. Perhaps it might also have something to do with the mathematics of an ellips. You can draw the function of a sinus wave using a unit circle, and a mathematical wave could basically be said to be described by a point on a moving, rotating ellips. Could the globule of gas which would later form the sun have been dense enough that, at least in an initial phase of its collapse, sound propagation was possible? Perhaps the gas' implosion into a star, or the subsequent initial explosions, would have propagated waves through the proplanetary cloud. Since these sounds would be random, it would mostly be a homogeneous noise, but consonant frequencies (ie harmonic notes), which interfere constructively and so amplify one another, might have travelled farther. No idea how to go on from there, though. I'm more writing this to encourage others to try and share their thoughts. If I'm the first to ridicule myself others might not mind as much. Still, of course, it could very well be coincidence. The problem is that unless we can properly observe the orbits of exoplanets, we can't find out, so as yet it's an unsatisfying answer.
  5. http://en.wikipedia.org/wiki/Harmonices_Mundi Why is this? The angular velocities vary in accordance to the distance to the sun, moving faster at perihelion, but what of it? The planets were formed of the same elliptical proplanetary disk, which explains why the ratios correspond so well, but I'm assuming that the approximation to musical harmonies can't be coincidental.
  6. OK, bad wording. I meant I couldn't identify it. Considering how crowded it is here, and how homogenized nature is, I don't think it very likely that I'd stumble upon an insect no one's ever named in the middle of a large city.
  7. I'd like to identify this insect. What species is it? You don't necessarily need to say anything else about it. I can look it up myself.
  8. How is the paratope of an antibody formed?
  9. If there are billions of neurons that might be the one the axon needs to connect to, does this mean that there are billions of different signal cues? And if so, how is this diversity achieved? How about negative signal cues? Where do those come from?
  10. Aha. I had always been under the impression that the neurons actually needed to send forth signals back and forth to simply sustain a memory. I'd first received this wrong information as a child and had since never found any information that explicitly contradicted this. Now it makes a lot more sense. Thank you.
  11. That's the thing — the activation. What does this activation involve? How are neurons activated, so that we become conscious of them? Unconscious memories, that is, those we are not currently reminiscing and therefore not conscious of, still consist of signals running back and forth between neurons, just as conscious experience. What's the difference? What's the "activation"?
  12. Your teacher probably didn't understand, because the abstracts don't contain a reference to AKG. If those articles do mention AKG, it's parenthetically. Either how, if you're diabetic AKG is no replacement for insulin. "Diabetics who have been prescribed insulin therapy are highly benefitted by AKG. Insulin helps cells to use up glucose for energy production, and AKG enhances the functioning of insulin. Therefore diabetics can maintain their sugar level by taking less external insulin." http://ezinearticles.com/?Alpha-Keto-Glutarate-and-the-Krebs-Cycle&id=1639827 Consult your doctor if you want to change doses of insulin. If you use it for bodybuilding: "Enrichment of a whole-protein–based formula with α-ketoglutarate did not improve protein metabolism or decrease muscle catabolism after major abdominal surgery." http://linkinghub.elsevier.com/retrieve/pii/S0899900702008444 According to this article, it only works when combined with arginine: "AKG supplements (15 grams per day for 5 months) have been shown to improve growth rates in small children. The AKG supplements resulted in elevated concentrations of anabolic (growth) hormones and amino acid metabolites, including insulin-like growth factor 1 (IGF1), glutamine and glutamate. In another study of healthy men, AKG given at 10 grams per day resulted in a 20-30% elevation in insulin (another anabolic hormone), which were not observed with supplementation of either Arginine or alpha-ketoglutarate alone." http://www.ironmagazine.com/review58.html
  13. Bit states? As I understand it, unconscious processes are digital and conscious ones analogue?
  14. My bad. I did read discontinuity planes to mean whatever it is called that I meant, but it was Dutch. Perhaps the term is different in English. They're apparently called plate boundaries. In particular, I wondered if there were old plate boundaries over Siberia, and if there were between England and Norway.
  15. Are there any old tectonic discontinuity planes known to exist, ie, which have stopped playing part in tectonic activity, and if so, where?
  16. Was there any difference in the youngest age the average woman could conceive over the recent millennia? Reading in Shakespeare that "Younger than [14 years old], are happy mothers made," this got me thinking. I had assumed that most cases of pregnancy at a much younger age would be morbid, perhaps even life-threatening. Is it possible that over a mere 500 years there has been evolution in this?
  17. How long does it take for the cell convert glucose into energy once the glucose has entered into the cell? Ie, how much time passes between the glucose molecule's endocytosis and the end of the molecule's electron transport chain?
  18. How many percent of species have become extinct in the Holocene? Ie, how large is the percentage of species that are extinct now that were still extant before the Holocene began?
  19. That's why I wasn't searching for a formula that would cover every possibility, just for examples. What I'm most interested in is, how much energy does a traditional Inuit (clothed) need to keep warm outdoors in Arctic temperatures?
  20. "Even when still…" What if the person is shivering? That way, the body can produce more heat. According to the diagram, at 23 C the body would have to produce at least an additional 70 watts to prevent hypothermia, excluding the unknown value of convection. So that's a total of more than 160 watts. What if it's freezing point? What's the highest number of watts the body can invest into heat while standing still, but shivering? Note that the 90 watts figure is due to the basal metabolism of the body, that is, the basic mechanisms it needs to stay alive: heartbeat, breathing, brain function, muscle tone, etc. This does not include extra heat production due to cold.
  21. How much power does the human body need to keep its temperature constant in different ambient temperatures ("ambient" meaning in the immediate environment, ie, under clothing)?
  22. See those letters in the sun glare? I have two questions: 1) where does it come from and 2) what does it say? It's probably the mirror image of a label somewhere on the camera. Upside down, it says "!R" or "IR" Assuming all letters are capital, the letter before the I is probably an N, the one behind the R probably an U — IRU.
