  1. Read this, might do the job.: http://www.specialistaggregates.com/bentonite-clay-natural-granules-p-1677.html
  2. This Wiki on concert pitch may help to answer your question. Prior to 1859 - when France set it at 435Hz - it was quite arbitrary within quite a large range of that. The act of tuning an instrument to itself, or with other instruments, is about minimising the sonically unpleasant destructive interference that can occur when out-of-tune notes are played together, so it can be done without a numerical standard, which started to get figured out about 1830.
  3. Go halfway and consider cyanobacteria which are the precursors of plants and photosynthesise.
  4. I found something similar and it had nylon in it and preserver; I think the nylon is what holds it together I Would imagine it is basically non-toxic otherwise there would be warnings about handling it. The stuff is waterproof - not penetrated by water - so I would think, at best, only a small limited amount of preservative residue from the exposed surfaces will go in the surrounding water which will dilute it to insignicance. If it were me I'd be happy to try it.
  5. He is trying to deliver verbally that which can only really be understood mathematically. AFAIK Richard Feynman has few peers in explaining very difficult ideas in layman's terms and if you can't understand him you are in a difficult place.
  6. It is a perfectly fine question to ask and have a light-hearted chat about. Some people need to learn to censor themselves and protect others from their more mardy moments.
  7. Neodymium magnets are the strongest. If you pursue that route again, and if you haven't used them yet, then they might be worth a look.
  8. Just throwing out there, but what about a magnetically-coupled stirrer - no need to make any holes? Basically you want a motor with a magnet on a spindle and the another magnet inside your sample.
  9. These two are pretty mainstream. Bear in mind, all the news about the conventional research projects are just 'snapshots' of the current state of things and may later turn out to be inaccurate but you do get a general feeling, after a while reading, where things are heading. http://www.sciencedaily.com/news/ http://phys.org/
  10. The BB hasn't been considered the beginning, starting from an infinitely dense point, for a number of years; it was a new epoch in the universe's evolution..It is consistent with a universe with no beginning.
  11. I don't think we know what any of the forces or fundamental components are ontologically. Scientists attempt to model things in a way that has a classical analogue i.e. that makes sense via our limted senses.
  12. Yes, true, and there's some astronomical telescope observers as well who are very good at direct drawing. I suppose it's more of lack of ability to make clever artistic abstractions that gets the idea across in an eye-catching and interesting way; graphic-design skills really. Studying advertising images might be good training.
  13. Artistic sensibility and science are disparate disciplines on the whole so the lack of artistic maturity is not surprising imo. Unfettered Imagination is not exactly nurtured in science is it?
  14. Geocentrism = Egocentrism
  15. A forum, such as this one operates, on more than one temporal level. To those who frequent it daily or so it's more like a chat site but to casuals its a long-term static resource. I often find myself looking at long-dead conversations in other forums in pursuit of information. We regulars find it annoying because it's 'old', but actually, If it's being necromanced it's a good sign that people still find it useful.
  16. OK. Thanks for the correction.
  17. Coke is mechanically homogenised coal so I don't think it has a natural crystal structure.
  18. If you'd asked questions you would have got educative responses but when you put up an idea that challenges the mainstream it will be subject to critique. Everyone goes through it, regardless of expertise or seniority. It's why the scientific method is trusted.
  19. Tar Birth of a Nation.
  20. I meant we can only do our best and we can't be the final arbiters of what was the right thing to do; we haven't got the benefit of hindsight. Also, it is by thinking forward, looking back, we may help to ensure our continued existence into the future. We need to keep our eyes on the wood as well as the trees.
  21. I don't think you appreciate the potential consequences of militarily engaging with Russia. It is imperative we pursue diplomatic solutions first before we dig our heels in. When and if historians look back at any conflict that may have happened in this era between NATO and Russia, it is important we are seen as having acted responsibly and without undue haste.
  22. A game is an activity with a challenging or competitive objective; whether against onself as a personal challenge, against others or against some device. Vacuuming a carpet can be a game; one may challenge onself against the clock or attach challenging conditions on how it must be done, which may test ones ability in some way.
  23. Why do people hate Einstein and Maths so much? it's a fairly constant theme I've noticed.
  24. The formation of the filamentous nature of the universe is modelled, like this following series, in a section about 140 million light years cubed. The bigger the scale the more stuffed with matter it appears; the gaps between the filaments are actually humungous if you can visualise it in 3D. There are animations of it in this link and more information if you care to look. The Lambda Cold Dark Matter Model suggests that this is how the universe is distributed in all directions. If you are asking what the universe looks like from some hypothetical external birds eye view of its entirety in terms of shape then I don't think scientists have sufficient data to extrapolate that to any high degree of confidence. This is a wide-angle sky survey image.
