  1. No. It's a reflex action- like when you put your hand on something hot + pull it away before you even know it's painful. (And that's before we get into the question of whether or not flies are conscious.
  2. Well, that may be true in your opinion, however, in fact, it's not. The reflexes can still happen even in a brain dead individual http://www.sciencedirect.com/science/article/pii/S0041134503012752 The classic "test of reflexes" is this one https://en.wikipedia.org/wiki/Patellar_reflex And if you get someone else to tap your knee just under the cap you will notice an odd effect. You see your foot move before you feel the tap. You can't have made, even an unconscious, decision to move the foot before you felt the stimulus.
  3. They do. https://www.thoughtco.com/do-insects-have-brains-1968477 Similar reactions are found in most animals, including us. https://en.wikipedia.org/wiki/Reflex_arc
  4. Not if you write it badly enough. I take it you actually meant "How many people are there in the White House Science Office?" The trouble is that if you miss bits out, it's impossible to know what you didn't put in. It could equally have been "How many people in the White House Science Office are scientists?" I'm fairly bright, but not psychic- so there's no way I could have known what it was that someone didn't bother to type. It's not very helpful to try to call me out for someone else's failure.
  5. Any minute(man) now, someone is going to reinvent the ICBM.
  6. A martyr could use a suitcase or a back pack (or even a car or truck). And, if he didn't want to die, he could park the car + walk away. So what use would a grenade ever be?
  7. Question: How many people in the White House Science Office (technically The science division of the White House's Office of Science and Technology Policy (OSTP) ) as of Friday close of business?" How many of them do what?
  8. Fundamentally, this is an "odd" question. I can, perhaps, throw a grenade 100 metres. Do I want to be 100 metres from a nuclear explosion?
  9. There are other isotopes with smaller critical masses (though not much) https://en.wikipedia.org/wiki/Critical_mass#Critical_mass_of_a_bare_sphere and these are even less accessible.
  10. How hot is it most nights?
  11. On a related note... Here on Earth, one of the things we do to keep track of our health is to weigh ourselves. NASA and the like are interested in the health of crews on space ships. How do they weigh them?
  12. Open the windows. Maybe put some insect screens over them. Apparently, I am now an international hero. Should I add it to my signature?
  13. If you really believe that the area needed to produce food for someone is some fixed quantity, and not dependent on climate latitude soil condition etc then you have pretty much proved that you have not thought this through and we can discount your opinion.
  14. 1400 years ago biology was not where it is today. 1400 years ago religion was exactly where it is today. That's the problem. Religion can't learn. And, because it can't change it can't get rid of an idea (like creationism) that is known to be wrong.- it just has to lie about it.
  15. Another way to look at the question would be, "if evolution isn't happening, what's stopping it?". We might, in principle, be wrong about the details, but the general idea seems almost inescapable (given a few reasonable assumptions).
  16. Just a thought. What do you propose to do with the cold wet parts of the world where pretty much the only thing which grows is grass? At the moment we use them to raise cattle or sheep (which can eat grass). Here in the rich West we might be able to manage something with heated greenhouses and such. Is your plan for those in poorer parts of the world that they simply starve? Or do you have some other solution?
  17. Swam coolers- or, as they are sometimes called, culture vessels. https://en.wikipedia.org/wiki/Legionella
  18. To be fair, any air flow is likely to help cool the car. However, from my point of view I would have two holes that let the mud, rain and noise in all year so the car didn't overheat on the few days of the year when we get much sunshine. It's not as if the air temp is the only problem with leaving pets or kids in the car.
  19. Web sites about gliding cite large tarmac car parks as good candidates for places where hot air will be rising. Black stuff isn't typically cool in sunshine. So, when you first park, you will be pulling in unusually hot air.
  20. It's common enough that there are jokes about it. https://twitter.com/thepoke/status/653110291249557504
  21. You seem to have made some assertions without any supporting evidence. Do you think that is going to convince anyone?
  22. On Jersey ( one of the channel islands) there's a zoo where there are two sets of climbing frames. One is in the chimp enclosure; the other outside. You can watch the primates (on either side of the fence) watching those on the other side. The symmetry is hilarious.
  23. I was in a hurry, The only VT I ever saw in a computer outside of museums was the CRT screen. In principle, you can go even more "old school" and use relays. You would need a dedicated power station to run the equivalent of a small computer, and I don't know how you could keep it cool. It would also be something like a billion times slower. I'm still not sure what question the OP was asking.
  24. You may want to discuss that with nuns, monks + priests.
  25. Why assume there is anything?
