  1. This is from the MSDS for Crest toothpaste:
  2. A minor correction: In physics, scientists don't say "deceleration" because "acceleration" is a change in velocity: it expresses both slowing down and speeding up.
  3. That article piqued my interest because it suggested worms might be the very beginnings of intelligence on the evolutionary scale.
  4. You can censor your own choice of forums to view in the New Content page. Go down the left-hand column of the New Content page then select Filter By Forum > Click on the forums you want to view in New Content > Click Save.
  5. Apart from the out-and-out preachers, I ask myself "Why do people want to talk about their faith on a science forum?" and I think it's often because they want to test it.against scientific thought processes. We will hardly ever know the effect on them but I'm sure some go away with new insights, like you say. If there weren't any websites like this one, spreading the scientific view to everyone, and not just the choir, religious doctrine can only continue unabated. I also agree with you that banning religion will only allow it to creep into mainstream stuff like it did before: no point history repeating itself. I hardly post in Religion but it's right that it's there. I'd hate to see this forum become too devout about science and excluding those who challenge it. We wouldn't wish to become like those we oppose would we?
  6. In your neck of the woods, one type of rare worm can grow to 140cm and 11mm diameter.
  7. Yes, it is better to speculate from what is known rather than from fresh air.
  8. I shall most definitely read it. I want to be an oligochaetologist when I grow up.
  9. Perhaps our emotions informs the decision-making process first then it is modulated by our conscious self; if necessary.
  10. Do you know, I thought you mentioned it but couldn't see it at the time. This one is a cleaned up version with no marks on the pages ...probably used OCR.
  11. I don't know the answer but it might help to ask yourself "What would be the evolutionary advantage of having the olfactory pathway so short and direct?".
  12. You can't rep someone in the phone version of the site unless you go into the full PC version ....which is not practical because you would have to zoom the page too large to see the rep buttons on each post.
  13. You can download The Formation of Vegetable Mould by Charles Darwin Gutenberg Press have scanned it and released it for the public in various formats or online viewing. If you want it like .PDF format then EPUB is like that. I use SumatraPDF which will open it as well as PDF and other formats.
  14. It seems you were given ok advice and the reaction products are safe; sodium sulphate, carbon dioxide.and water.
  15. If your ears were wired up to your visual cortex would you still call the stimuli "sound" even though the sensation you perceive will be in some visual pattern?
  16. It's not about solving; it's about addressing what we mean by things. In this instance, is sound an objective phenomenon or is it observer-dependent? What do we mean by sound? It's useful in the sense that it makes one think about the way one thinks and forces us to look at our language and it's specificity.
  17. It would seem that they pull pine needles by the base because that is the easiest way to pull them into their holes. They do this in a tactile manner and will reject it if it is not orientated the right way the first time they pick it up. The function of these objects is to block the holes up in colder weather to stop them drying out due to air-circulation and reduced humidity. They will also strongly tend to pull broad-based leaves by the pointed end. Darwin isolated this tendency using paper triangles for them to go at and the pointed ends tended to get pulled in first. http://www.psychology.gatech.edu/psyc3031/Behaviorism%20Behavior%20and%20Philosophy/1982%20-%20Vol%2010%20No%202/05%20Darwin%27s%20Earthworms%20A%20Case%20Study%20in%20Evolutionary%20Psychology.PDF
  18. You are absolutely being offensive. Just because it doesn't interest you doesn't mean it isn't for anyone else. I used to think simplistically on this matter, like you, but I wanted to explore this more. If it was such a useless, trivial question, why is it so often repeated? As much as you might like to think it, physics doesn't have all the answers.
  19. You may well be right but I took 'synthesizing' as the operative word in his question. Won't be the first time I've barked up the wrong tree. .
  20. You personally, as an individual, can't do it; it involves seriously high energies and equipment splitting or fusing atoms. You are talking about acquiring a fission reactor, fusion reactor (no working model) or particle accelerator. Nuclear transmutation is a government-level undertaking.
  21. I never defined a person in prison as a person who is necessarily causing harm to society or the fact that they are in prison denies them the right to vote. I also never said that it should be held against a person forever: A responsible, pragmatic and considerate panel has to define where the boundary is but I think being a convicted felon is insufficient and unjust, given some of the stupid laws one can finding oneself breaching, as you rightly said.
