They didn't "allow" him to anymore than anyone else in New York State. He was elected democratically to make those types of decisions. Hindsight is 2020...at best. In this case it looks like that was a mistake, but we still don't fully understand all we would like to know about Covid 19.

That's the circumference. The area is pi X r squared, or (pi X diameter squared)/4. cross posted with Swansont

try pi X diameter squared /4

I seem to recall there was a plan to have Australia and New Zealand maintain the same restriction zone rather than each country restricting everyone.

True...but I did hear on TV that there are a lot of cases where people don't get sick, or only mildly get so. So I guess some of it is true?

Hi Studiot I understand what you are saying (makes sense) but for most purposes there is very very little difference...to the point that they are commonly interchangeable. The gravitational gradients we generally deal with are pretty small relative to the objects we normally consider in mechanics, and any reorientation of the object does insignificantly little to change any difference...they pretty much move together. When someone says COG they usually mean COM.

It's common to take the moment of inertia of a body about an axis running through the center of gravity. It represents the inertial resistance to accelerating the body rotationally about that particular axis, and can depend on the choice of axis. I'm not sure that is what you are after though.

Surely you're joking... ...Mr. Joigus

But first note that Curious is from the UK... To the OP" They will have the same velocity upon release...assuming they both start accelerating with the same initial velocity... Both "going at the same acceleration" doesn't tell you that on it's own. Assuming that's the case it comes down to how the extra mass effects drag. If it's linear then they go the same distance. But it could readily be greater or lesser than linear with the mass, depending on your conditions. Using Curious' example on a hard surface a soccer ball travels further than a beachball. Same example on a surface that will yield easily to weight and the beachball goes further while the soccer ball "digs in". For something sliding on a wood floor it depends (mostly) on how the coefficient of friction is affected by the extra weight. If it's the same they stop at the same point. (air resistance aside)

We have focused more on mechanical ventilation. Here is a WHO publication to natural ventilation for health care settings if you are interested. https://apps.who.int/iris/bitstream/handle/10665/44167/9789241547857_eng.pdf;jsessionid=39488D09F98E3FB5C175C9CC2225AD4B?sequence=1

Nothing technical, but here is an interesting article based on some Canadian Engineers considering the problem. There does seem to be some disagreement as to how much the spread is airborne, other than immediately from droplets being probably most significant, but they are primarily concerned with the control that ventilation can improve on: https://www.thechronicleherald.ca/news/canada/covid-19-likely-spread-by-building-ventilation-say-canadian-researchers-working-on-an-hvac-fix-442278/

One thing that is generally accepted with respect to avoiding airborne viruses is that being outside is considered better than being inside most buildings. Obviously a big part of that is ventilation by somewhat random dilution typical of outside conditions. So more of the same and more make up air might help. The key is to make sure that it does .

My concern is with the ones in between. Unless there is reason to believe droplets that size are acceptably safe, and I can't see how that is likely. Good point with respect to evaporation. I think that is considered in the duration of the risk from airborne droplets. https://onlinelibrary.wiley.com/doi/full/10.1111/j.1600-0668.2007.00469.x

Enough is enough. I'm not sending INow any more photos.

I guess if I had an infinite amount of time I might keep it, just in case I might run out of things to read. If it turned out to be worthwhile I certainly would be glad I kept it.

To win the Primary or the the election? Both? I'm not sure what an old entitled codger like myself misses out on. (missing out on any consideration for Yang, possibly) My pick based on personal preference for Biden's VP would be Gabbard. To borrow a quip from CY on Warren: Of course Tulsi was one of the candidates with the most integrity. As you know that basically means low electability. But hopefully there was some young girls (and boys) paying attention...

Thanks (I wasn't really comfortable with "isn't", unless I left out the "they")

On that subject, should Biden have announced that he was committed to choosing a female running mate? My personal belief is that he should not have, and simply chosen who he thought was the best candidate. However, if he was going to do that (choose a women regardless), should he not just have kept that to himself, and picked a woman as running mate as presumably the best choice available?

It's easy to underestimate people. Moreno seems to have been convinced themself that people of Papua New Guinea are quite talented, and apparently they isn't from there...so maybe there's hope for them. Seem OK? Or should "isn't" be "aren't"?

That works. I use "they", and "them" alot for singular. What should I have used here? "them" still doesn't seem right in that sentence.

It's easy to underestimate people. Moreno seems to have been convinced himself (herself?) that people of Papua New Guinea are quite talented, and apparently isn't from there...so maybe there's hope for him.

It should have been obvious to her not to overplay her hand...nevertheless, she persisted! She would have been the oldest POTUS on day of inauguration if she had won this time. (though as she famously pointed out...youngest ever female) But she certainly is younger, and seems far healthier, than Biden or Sanders. Understood. But I still believe that is presumably the excuse...if her accusation is completely honest.

Exactly...the type of losing identity politics excuse that is simply too easy for grownups to see through. I hope all those young girls come to understand that. Warren ran a faulty campaign and wasn't deprived of the nomination by straw men.

Possibly POTUS earlier... I'm skeptical at least to the point that I would not hold it against Biden. I would neither believe or disbelieve her story at this point, and not have it affect my vote either way if I had one. The onus of proof is on her for that particular purpose, regardless of how fair that may seem to some people. Presumably due to the MeToo movement, there is less of a stigma attached to coming forward. That isn't a bad thing, but it doesn't oblige us to take any accusation at face value. Agree. Being a woman in the Democratic Primary was an advantage Warren badly overplayed.

With all due respect to the point you are trying to make, we have no idea how intelligent Gauss' mother was.
