That's a good reason, thanks for the info...

This position paper cites a couple of research outcomes regarding health impact of DST https://doi.org/10.1177/0748730419854197. The main argument is based on misalignment between body clock and what they call social clock.

After reading several posts in this thread I wonder how many commenting have kid schedules, and or work schedules, I may be misreading this but everyone does understand that the time changes for everyone not just the school kids... right? The main problem with dst is that the sun pays little to no attention to human clocks, while time changes do concern us and they should, I worked for DuPont, rotating shifts, I changed my schedule every 7 days and the only way I could deal with it was to live like I was on the same schedule as everyone else or to be more precise I had to live like my shift was always 8 to 4, I ate, slept, and worked as though I was always on day shift. I slept, ate, and worked as though every day started at 8am even though it could be 4pm or 12am. If the sun followed DST there would be no problem and no conflicts other than the ones we already have, if not for the Sun's lack of cooperation shifting back an hour should have no problems. Actually changing the time of school, work, or other activities would create problems for everyone... initially anyway. If we really wanted to maximize daylight activities then we would have to actually change the time we start our days and probably on a sliding scale as the seasons progressed. In the past we changed our work schedules with the sun, we got up with the sun and went inside when the sun went down if not go directly to bed, we knew the day length changed as the seasons progressed but we changed with it instead of trying to change the time. It seems to me at this point that DST as we know it now is the lesser of two evils in trying to fix this "problem" all the talk of starting school late or changing work schedules or relying on neighbors to take care of your kids is just not tenable in the real world. I feel you dude, SAD is a big part of winter life for me, I feel like I need to crawl in a hole and sleep for weeks... Goa?

Similar effect allows bacteria to withstand much higher osmotic pressures than eukaryotic cells. In this case, it is the line-square rather than the square-cube law. When you decrease the size by a factor, the ability of a membrane to withstand tear decreases by that factor while the tearing force decreases by the factor squared. Thus, a bacterium that is 100 times smaller than a regular cell can withstand 100 times higher osmotic pressure.

Ants can do this because of something called the square-cube law. When you increase the size of something by a given factor you increase its surface area and the area of its cross-section by that factor squared, and it volume (thus its mass) by that factor cubed. The strength of limbs are dependent on the area of their cross-section. Which, as the size increases increases at a slower rate than the mass/weight of the animal. Increase an ant to the size of a man, and it wouldn't even be able to support its own weight. Conversely, shrink a man down to the size of an ant, and they'd put a ant to shame in terms of strength. So in terms of higher gravity, this just means that smaller animals would generally fare better.

What would be the point? Besides the extra cost, which many people can't afford, the children wouldn't get that hour of sleep: they would have to get up even earlier, be rousted out, rushed through morning chores, and trucked off to daycare in the dark, in time for the parents to get to work after dropping them off - so they're tired even before school begins. What have they gained by eliminating DST in schools? In any case, why should parents and children be required to make sacrifices for the convenience of WWI industry? Just stop screwing with the time of day and let each business and school district decide on their optimal hours of operation.

Just kidding, but assuming Putin to be one of his creditors, and abandoning Trump faster than anyone else.

I remember many years ago, working for a chemical waste disposal company, a young fellow employee and I, had been sent to sample a vessel containing cyanide electroplating solution, at a decommissioned plant, about 4 hours away. We brought all necessary PPE with us, such as impermeable HazMat suits, gloves, boots, and SCBA breathing air with full face respirators, just to be on the safe side. When we got to the decommissioned plating plant, we found about a dozen workers doing the clean-up, on their lunch break , sitting around the open top vessel of cyanide solution, eating their lunch. We decided not to scare the bejeesus out of them; quickly took a few samples, with dip tubes, wearing just gloves, and left. I hope there were no cats in the area.

But now you have the issue of parents possibly not being home at the beginning of the day to see their kids off, unless they, too, adjust their schedules - if their employer affords that kind of flexibility. Younger kids not supervised makes a lot of people nervous - more than when I was young.

This is one of those “why are things the way they are” that physics can't address, because we can only observe how things behave. Bare charges and their electric field come as a set.

I enjoyed that, too. Am sure the Senators favorite part was that she was played by… Scarlett Johansen And one more bc, well, bc snark is how we process modern political pain
