  1. Certainly. Tough doing that when you're pretty much alone doing it. We are all wired to try to survive, and Putin and his ilk know how to exploit that. Hopefully the ones on the sidelines start showing up, in numbers Putin can't control. Noteworthy though that when Ukraine was attacked many expatriates came back to help.
  2. They seem quite willing to support the atrocities...having to take partin them with their own lives on the line...not so much...
  3. Is there any space where no electromagnetic radiation exists?
  4. Where does the video make that claim? As far as I can tell it assumes a constant flow in the pipe, and with it a difference in pressure due to the different velocities in different diameters. In practice this is true except for a loss of pressure downstream due to friction, which Bernoulli's principle doesn't account for.
  5. Generally speaking, it doesn't. That old explanation has long been debunked. https://www.grc.nasa.gov/www/k-12/airplane/wrong1.html (seems others have already pointed this out over a week ago) Bernouilli's principle is somewhat straightforward, but complex with regard to wings as it is incomplete. Shear forces (especially affecting boundary layers and turbulence) are not taken into account. +1 You can also fly an asymmetric wing plane upside down, though less efficiently. The Bernoulli effect is still there despite the curvatures, as it is with the flat plate. The air still gets accelerated on the upper side. Ultimately it comes down to Newton explanation, with air deflected downward and/or ground effects. (Not the explanation of Newton himself...he thought the lift was from the air hitting the underside of a wing where it's primarily from the reduced pressure on the top when the wing is not in stall) You might have trouble getting it in the air. Once at speed a flat plate can be quite low drag, relative to a typical airfoil assuming the same planform. (but as John pointed out...not the best structural profile.
  6. Hopefully, in some small way, some minor portion of his brain is a little embarrassed meeting up with Xi after his recent war results...maybe feeling a little "special" with his special operation.
  7. Yes. Think higher prices might decrease demand? Yes. If granny and the children are flying in their private jets they can pay the increased prices and the extra taxes can go to other's grannies and children who can barely afford to heat their homes.
  8. +1 to the OP. If they knew what they were doing, and had the gonads to do it, they would put significant taxes on energy (or at least fossil fuels...aka carbon taxes) and use the taxes to help those who could least afford it, with no requirement for them to use any energy at all. So essentially increase the price of energy, and encourage conservation, rather than subsidize the use of it by holding the prices down.
  9. LOL. Like your myopic one-sided perspective fits in every employer/employee relationship.
  10. Maybe Trump simply wasn't aware he wasn't allowed to keep and store top secret information. Maybe he just saved it in case he needed it to extort someone to his advantage or for some other good purpose. It wasn't like he would use it to hurt his vision of America. Maybe he thought people just needed locked up for mishandling emails... The American people didn't make him President because they thought he was some kind of legal expert.
  11. Inquiring minds want to know?
  12. Have they check in Hunter Biden's briefcase?
  13. Apparently it's complex enough for you to have yourself confused. Are you, or are you not, employed by the government?
  14. Agree. And I didn't use it in that incorrect context.
  15. Yes. Correctly. I correctly used target as a verb. https://www.britannica.com/dictionary/target 1 : to aim an attack at someone or something The missile attacks targeted [=were aimed at] major cities. = The missiles were targeted [=aimed] at major cities. Thieves often target tourists. drugs that target cancer cells He has frequently been targeted by the media. [=he has been the target of frequent attacks by the media] 2 : to direct an action, message, etc., at someone or something The commercial is targeted [=aimed] at children. government programs that are targeted at low-income areas = government programs that target low-income areas
  16. Who negotiates with your employer, on behalf of yourself and fellow Union members? You quoted the bold and replied:
  17. Public service unions...the ones that negotiate with governments...because that's the source of the money they run on... ...their cash cow... ...their bread and butter... ...or choose your term with the connotation you prefer...
  18. Follow the money...if you can't trace what government unions get paid back to government money...I can't help you. LOL. So words matter, but you feel free to attribute words I didn't use, to ones I did. Give your head a shake Dim.
  19. It seems Trumps team is slowly uncovering the truth for all the world to see. The US has been writing fake-laws since as early as 1917!
  20. LOL. From the political humour thread. (too good not to be included here as well)
