  1. A flat white cloth sheet, or even white paper, would look better than crinkly, cooking foil aluminium and you'll still get some light. Home Depot do the Gila stuff, Swansont mentioned, and it's called 'mirror privacy window film'. i think that's a common store in the US, isn't it? http://www.homedepot.com/p/Gila-3-ft-x-15-ft-Mirror-Privacy-Window-Film-PRS361/100196546
  2. Is mylar just a trade name for that type of film? i thought it might be different to the stuff used to reflect some of the light off windows rather than all of it.
  3. You can get Mylar mirror roll, which is perfectly flat, but it's opaque, I think.
  4. A white lace-type drape might help a bit, not too dear and shouldn't attenuate the light level too much. I think intensity-wise it will reduce by about a half. i close my curtains on the sunny side to reduce the greenhouse effect.
  5. Panspermia is about origin and abiogenesis is about the process; whether it occurred here or elsewhere, it is still abiogenesis.
  6. Evolution ultimately starts from the inherent behaviour of the atoms in the periodic table and subsequent emergent behaviours arise with each level of increasing molecular complexity and interactions between those molecules. 'Evolution', strictly speaking, is actually the change in the frequency of alleles (traits) over time; this makes it an unassailable fact because that actually happens.
  7. We'll never understand it all but if we keep reading worthwhile stuff we will know more than we did yesterday.
  8. Geons, Black Holes, and Quantum Foam: A Life in Physics
  9. That's the stuff. Yeah, would imagine any potential toxicity will be pretty low and very temporary while it was setting. BPA is used in the production of food containers, including water water bottles. I think the real hazard and precaution protocols is with the raw chemical, when handling it regularly, which is the case with many chemicals that are otherwise safe in exposures experienced by consumers..
  10. There's enough conventional science to keep you going for many years on the subject. I am of the thinking that one should fully understand that before looking for alternative explanations.
  11. IIRC, a friend, who worked with water supplies, used to use a sticky, waxy wrap that you could mould around a leak to seal it.
  12. A 'field' is a set of values of amplitudes of some force distributed over a set of co-ordinates.
  13. What are all the applications it says? Can you link to it?
  14. I know you aren't conversant in the this field but I appreciated the other angle you presented.
  15. Right. Cheers.
  16. Are gravitons visualised as tiny perturbations/excitations in the spacetime field as a means to try to quantise it?
  17. Couldn't gravity be emergent i.e. it didn't exist because other conditions weren't met at that point?
  18. Absolutely, you need a thorough understanding of the core knowledge but that 'germ' of the new idea probably came from some other unrelated knowledge. For example, Einstein was around at the dawn of cinematography, when time-lapse films were avant-garde, and, apparently, that inspired him to ask himself if time actually behaved like that. Thinking about it: we can throw serendipity in the mix as well.
  19. You mean a paradigm change? If so, then the idea might be taken from a completely unrelated field and an association/inspiration made. That's the work of a genius mind.
  20. The more 'pieces' of knowledge you have, the more permutations are possible in creating new combinations of those pieces.
  21. People may have different criteria as to constitutes caring and, therefore, one may, in the eyes of another, be seen to not care. Sometimes, people say they care but it's only a feeling in their heads and never manifests in an actual physical act of caring and, as such, the recipient senses nothing.
  22. Pure imagination without the anchor of knowledge is just vapour.
  23. Isn't 'theoretical' or 'bleeding edge' chemistry more the domain of physics since the underlying or fundamental mechanisms are physical rather than chemical?
  24. You are not yet ready to countenance the finite nature of your life and, so, create other possibilities. It is not an easy task to embrace the former but the realities you will surely experience in the future will make it more desirable.
