  1. Here's a 24kWh battery for cars. It's about $14000. It's probably got about 4000 18650 batteries in it. Think about the problems of getting rid of the heat in the middle of that box. It's a serious engineering exercise.
  2. Best we can hope for is to have an intersubjective consensus.
  3. They do in electric vehicles; there's a few thousand single Li-ion cells in them. I've no idea on the specifics.
  4. I think your error is in your conception of the mechanism of the BB as an explosion from a point, out into a pre-existing space. Wherever you are in the universe, evidence from the BB is moving towards you. The BB, and expansion itself, is happening everywhere where gravitational attraction is weaker than the force of expansion.
  5. A fundamental property of absolute truth, I would think, is that it is constant in all cases.
  6. Keeping on the relativity them - which we know to be true - it would seem to me that the absolutes (universal truths) could be those properties which are invariant in all frames.
  7. Truth is relative. I'm going to write a paper: On the Relativity of Truth.
  8. People want to know so that they can respond appropriately.
  9. Yes, it's about 'how', not ''why'.
  10. AFAIK the casimir effect is all around the plates, it's the difference in pressures between the plates - which is less in between - vs around them. As you decrease the distance, the longer wavelengths won't fit which creates a pressure deficit relative to the outside.
  11. Added to my shopping list.
  12. Wild Assed Guess... one is talking out of ones bottom.
  13. Yes, I think you only need a couple of ounces of complete protein a day. Mine mainly comes from milk but I do have chicken 2 or 3 times a week. AFAIK eating any more than that just gets deaminated into glucose and waste products by the liver.
  14. What size compressor have you got? I want the smallest I can get away with for a 16 gauge 2" nailer.
  15. On making mistakes: "A master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell." I'm asking myself: do I need a finish nailer?
  16. He certainly knocked it out of the park when it came to persevering in the face of adversity.
  17. There's a sizable bunch of clever people doing woodwork. Some luthiers, to name one group, can talk science with the best of them.
  18. The trouble with vegetarianism, with no animal sources, is that you have to fanny about making sure all your nutrient bases are covered, otherwise you could end up with deficiencies.
  19. i hope the momentum can be sustained long enough in the the younger US population, so it impresses them for long enough, that in a couple of decades they will be the lawmakers to make that change.
  20. i've come to realise that the NRA are the doormen of the gun industry. The gun industry pay the NRA to keep people off their backs. Notice how the arms manufacturers never speaks? Protesters need to get them out in the open and start making them speak. Interestingly, .pre-1960, the NRA supported gun safety and control. The fact is, whatever gun control laws are enacted will hurt gun sales.
  21. I think you'd have to look into epigenetics.
  22. Strange answered.
  23. Gravity, so far, is the outlier in a quantum description.
  24. Noted, but notice it does say "Often", which allows for exceptions. If I was doing something long-term, I would be drilling my GP or the NHS Helplinefor contraindications... I wouldn't be asking here unless I wanted some particular academic detail.
