  1. For an average individual the medical community seems to suggest a healthy resting systolic blood pressure of no more than 120 and diastolic blood pressure no more than 80 and a resting pulse pressure (the difference between systolic and diastolic)be no more than 40. So given a slightly elevated resting systolic pressure of say 130, what would they like the lower number to look like? And why?
  2. I can sympathize with the apparent helplessness felt by the Russian families, but I would have more respect as well as sympathy for them if they condemned the Russian invasion rather than suggest it be done in a different manner. “They are prepared to serve their homeland but according to the specialization they’ve trained for, not as stormtroopers. We ask that you pull back our guys from the line of contact and provide the artillerymen with artillery and ammunition.” https://www.cnn.com/2023/03/12/europe/russia-mobilization-putin-protest-wives-mothers-intl-hnk/index.html
  3. Right. Makes sense given the weight, dimensions, and airspeeds involved. I thought the Ukrainians themselves were experimenting with wings to extend their target range. I'm not sure where I heard it but IIRC it was mentioned as a possible explanation for a fairly recent bombing beyond HIMAR range. I would provide a proper link but can't remember where I came across it. Edit: their current HIMAR range
  4. I suspect their families have much less influence at the Kremlin as well, and they probably have much less access to non Russian controlled information. Fits nicely into Putin's playbook.
  5. Maybe Putin and company care about the lives of their soldiers after all...as long as they are of a certain ethnicity or come from certain regions such as Moscow:
  6. Do they not do both? Control flight plus add range or payload? https://airwingmedia.com/news/2012/boeing-adding-wings-to-jdam-bombs-to-triple-weapons-glide-range/
  7. I think it comes down to how much lift is actually needed, and more about the drag, or drag to weight (though weight would affect the lift requirement). Baseballs have been thrown significantly further. A low aspect ratio shape of the same scale would likely have less drag, especially given the range of Reynold's numbers involved and the fact that the low aspect would yield an effectively higher Reynold's number. Interestingly with regard to the war in Ukraine, this subject would reflect on the use of the wings being added to bombs to increase their range, the weight, scale and speeds involved affecting the designs. Another thought is that higher aspect wings would require more drag at the tail to control any yaw and for directional stability. Something lower aspect or swept designs do more inherently.
  8. As the Special Operation (AKA war) approaches the one year mark it's interesting how both Putin and Prigozhin are indulging themselves in their to each unique combination of lies and "see what you made me do" blame of others for their mistakes and incompetence. It would be hilarious if not so tragic for both Ukrainians and the Russians they are responsible for.
  9. Fair enough. I'm satisfied that Newtonian Gravity is Galilean. Less so that Galilean gravity is the same as Newtonian Gravity. It seems to imply that Galileo got there first, and he really didn't come close, even while making a substantial step toward it.
  10. So any model of gravity under investigation, correct or not, that meets those criteria is Galilean gravity?
  11. So Newton is famous for coming up with something a guy who died before he was born already knew? Galileo recognized that different masses accelerated at the same rate. Newton went further and recognized the distance effect of the inverse square law which explained orbits.
  12. Correct me if I'm wrong but wouldn't "Galilean gravity" not recognize the inverse square law postulated by Newton, but simply be a close approximation locally just as Newton's was more broadly to Einstein's relativity? Don't we utilize all 3 today?
  13. Arguably the vice tax on cigarettes helps pay for the extra public health care required. Though of course not directly.
  14. +1 but 4 minutes in had to turn it off. The Russians, as a people, are as responsible as Putin for what's going on. Respect to the brave ones that speak out against, but the rest not at all, and the worst need to be held accountable. I don't get the asymmetry in the rules of this war. Give Ukraine the weapons and let them use them against any military target that targets them. That, or bow down to Putin and admit his threats work, and stop funding the war.
  15. Looks like Trumps former campaign chair S. Bannon is heading to jail. https://www.cbc.ca/news/world/dc-bannon-sentencing-congress-1.6623755
  16. ...and potentially the extra deaths and suffering of course back in 1945 and beyond (just in case anyone not knowing you misreads that) Agree the next guy could be worse. Most of the "bravest" (cowards in this case) willing to speak out in Russia against how the "special operation" is going seem to be pushing a harder stance against Ukraine, and the Kremlin seems to have far more tolerance on that side than moral stances against killing Ukrainians, civilian or otherwise.
  17. Maybe frontreal or backreal...certainly not sidereal.
  18. You don't believe in a Suntanman God do you? You're better than that... No one needs moonscreen. (full disclosure: no idea what Sensei is on about)
  19. Like you he calls them the way he sees them. That's why they call it the Dyer straights...
  20. I'm worried the grannies would get to me first. I'd get the last laugh though...I haven't rotated the foodstuffs in my bunker since November 1962.
  21. LOL. (fortunately no one heard me) Now you have me picturing a bunch of settlement idiots preparing for a professional tryout.
  22. It seems like the retreat from Lyman was delayed due to the Russian command structure...possibly even waiting for the pomp and circumstance celebrations in Moscow to end so they could consider getting out of an area they just claimed to have annexed. I wonder how many Russian soldiers that cost them?
