Out of curiosity, and related, do you guys tend to hear/use "heat index" or "wind chill" as part of describing the weather?
"Heat index" when it's an increase caused by humidity, "wind chill" when it's a decrease caused by wind.

@mikehurley said in In other news today...:
Maybe it's regional, but in Minnesota we tend to talk about humidity with the dew point. So in general a dew point of 60F starts feeling pretty gross and at 70F that's pretty miserable. Obviously the % humidity is the dew point relative to the temperature so those aren't exact lines in the sand, but it's pretty reliable. So what's considered the equivalent % to those approximate dew points, or at least how I described them?
100% (relative) humidity means the dew point is equal to the ambient air temperature. At 90% relative humidity, the dew point is somewhere around 3-4 degrees lower than the ambient air temperature; @pie_flavor's example of 80°F ambient temperature and 90% humidity would mean that the dew point was 77°F.

Not here in CA. All the time when I was in northern Illinois.

@carnage Whatever Google says. All I know is I had great fun in 80°F at 90% humidity for three weeks, even if I started sweating as soon as I got off the plane and didn't stop until I got back on it three weeks later.
That wasn't sweat, it was the humidity in your clothes.
Did wonders for my skin.

How badly are your railroad lines laid if a 86 degree day warps them? Holy crap.

No doubt! We don't start worrying until it gets into the high 90s. And our track has been converted into single continuously welded tracks.

The bigger the size of temperature differences over the year, the more expansion joint space overall (bigger joints or more of them) you need.
Temperature range, yes, but I think @boomzilla was saying the train tracks wouldn't notice the humidity.

Well. Apparently "low-income" there is nearly 3 times my salary.

Well, that's not true. With high humidity, the tracks rust a bit on the sides of the rail...

@polygeekery How long would it take for an ICBM to fly from the US to the UK. 'Cause we have more nukes than Jolly Old England.

Mmm, my back-of-the-envelope calculations say 20 minutes. (And I've probably ended up on a watchlist for looking up the coordinates for the closest applicable AFB so I could do a GCD calculation.)
Edit: I forgot to account for the distance the target moves during that time and I'm shit at ballistics calculations anyway, so call it 25 minutes.

@benjamin-hall it would be funny if alcoholics were helping to reduce CO2 levels in the atmosphere.

In the mountains of western Colorado I heard "wind chill" a lot, because that could drop the apparent temperature by a significant number of degrees, and the difference between 40°F and 25°F can determine how quickly you would develop hypothermia.

I still remember one winter in the Chicago area where actual temperature was -40F and wind chill was -70F. Brrr. (Schools closed,
Stay Inside
warnings, etcetc) Of course, I went outside for a (very) short cross country skiing slide. Young+Dumb time (just out of college).

Sure it is. But the amount it moves isn't going to matter with a nuke...

Is there any feature on the earth's surface that is considered to be not moving due to plate tectonics?
-
@dkf I'm fairly certain that relativity allows you to pick a moving reference frame and consider it stationary.
-
@mott555 Only when it is undergoing linear movement in spacetime (so under freefall in gravity). Rotating frames of reference are very much detectable as moving.

I'm not sure it's that important when we're talking about a tectonic plate rotating at an inch per century or whatever.

Does some of it become the carbon in the extra fat you start carrying around or is that all from the organics in the beer?

It matters for psychological reasons though. My calculations involved dropping the W78 right on Windsor Castle. :(

I was talking about the rotation speed of the Earth. It's not negligible (it's about 1,000 freaking miles per hour).

London moves ~215 miles in 20 minutes, due to the earth's rotation. Washington, DC moves ~270 miles, because it's at a lower latitude. This motion, as well as the air currents between the launch and target locations, need to be taken into account if shooting an ICBM that distance.
-
@jaloopa Probably. But that's a rounding error. The solubility of CO2 at room temperature & atmospheric pressure is tiny, just enough to give it a small acidic taste (dissolved CO2 forms carbonic acid). At much higher pressures, it increases substantially. So opening the can/bottle (releasing the pressure) eliminates the vast majority (probably 99.9+%) of the CO2 in one burst.
I'm not sure about how well CO2 is absorbed through digestive tissue, but I'd guess most of the absorbed CO2 gets passed into the lungs and exhaled. CO2 is pretty darn stable--it takes a crapton of energy to turn it into long-chain organics. Much more energetically favorable to go the other way (breaking down the long-chain organics into CO2 and water).

Eh, it's close enough. Just make it a manned missile so someone can make the necessary corrections en route.

Didn't realize it was that much... Guess it will matter then!

The air currents are more a matter of final adjustments upon reentry. The missile will spend most of its time outside of any significant atmosphere.

Be careful, you’ll need to be sure your populace is correctly distributed, or you may capsize once the towing starts.

This. Everything is relative to me, since I am my own point of reference. Everything else (including myself) is moving relative to me.
