  1. Vaccine questions It seems the Phizer vaccine may not be the only option upcoming. Any harm, generally speaking, in taking more than one vaccine targeting the same thing? I'm not talking about follow up shots of the same vaccine. I would expect one would not take 2 at once, but spread them out sufficiently to allow time for an immune response. Would taking an early one exclude or delay taking a possibly better future one?
  2. Probably those that might expect the Spanish Inquisition (hint: nobody...)
  3. Ugh...I thought mine was gross!😅
  4. Salute to 2020 Ice Cream Flavour:
  5. +1 iNow https://www.cbsnews.com/news/million-maga-march-washington-dc-trumps-motorcade-passes-supporters/
  6. I guess if they're going to take us for nice walks and pick up our poop...then signal away!
  7. The rich ones get tired of that artificial crap. They await fresh signals from emerging but naive intelligence...
  8. The closest, Hipparcos 43587, is about 41 light years away, so we still have a number of years before the aliens come and eat us.
  9. This seems to be the recommendation when ceiling fans are used. examples: "Rooms where ceiling fans are used should have an upward airflow rotation". http://www.algomapublichealth.com/disease-and-illness/infectious-diseases/novel-coronavirus/covid-19-advice-religious-services-rites-and-ceremonies/ or ï‚· "When using ceiling or portable fans, use upward airflow rotation": .https://www.toronto.ca/wp-content/uploads/2020/02/8d59-Fact-Sheet_Novel-Coronavirus.pdf but no explanation whatsoever as to why... They must have gotten it from somewhere. I would suggest, without knowing their reasoning, that ceiling fans on their own aren't great in either direction without knowing more about the air flow patterns that they facilitate. Upward flow where people tend to accumulate may be better than downward turbulence directed at them (and then heading toward others), but why should the air not be drawn downward as laminarly as feasible and removed or filtered?
  10. Actually his refraining from rolling in the Trump mud and at least seeming to focus on working toward governing for everyone is what has impressed me. Pretty uncrowded territory for the last 4 years...hopefully he can maintain it.
  11. One other possibility, or possibly contributing factor, is that the increased straining forces on the fan blades affect the blades unequally, leading to them being better balanced.
  12. Bumped into this on youtube: Not sure why it came up watching and listening to Helen Reddy (recently deceased), but thought it might be of interest here.
  13. Generally speaking, but we can't do everything outdoors. What we can do is try to improve indoors to reduce the difference.
  14. A good percentage of the time yes, it means you would have survived where you otherwise would have perished. On topic, good ventilation design for Covid risk reduction should reduce risk of Covid spread and subsequent deaths. Eventually of course we'll all be dead, but as long as we are happy it would seem reasonable to delay it as long as possible.
  15. Why wear a seatbelt when you can still be killed while wearing one? Risk reduction.
  16. Also the expansion will affect a change in temperature from ambient, so the reading may change as it settles toward the new equilibrium. Any moisture changing state would also have an effect.
  17. On a more serious note, anyone else been impressed by how Biden has handled himself as President elect so far?
  18. Hi Enthalpy Any English translation of that article? It looks like a good one. Back when I was a kid sailing competitively I remember crossbow setting the record of 26.3 knots and doing rough calculations as to how to beat it (rough calculations was all that was necessary...the trick was stability and control, so making it actually work) We now have ocean yachts that can average that for 24 hours in good though less than ideal conditions.
  19. But will they stand by while the next administration insists on total defunding of every law enforcement agency in America? 😜
  20. At-any-cost is a little strong, but that's a very valid point.
  21. It's not uncommon, for example, to use it to refer to a substance in more than one phase. It is said that the phases coexist. I would think that that would be using the default meaning of the term for physics.
