Why, do you have research to indicate that mental toughness is such an important factor, and that amateur high school kids have more of it than professional runners ?
At any rate, this arbitrary milestone would have been achieved long ago if the wavelength of light emitted by exited caesium 133 atoms were only a tiny fraction of a percent longer
I know, but we're talking about refurbishing an old analog meter and using it today. And it's not just the 1% difference that makes it tricky. Even seeing the difference between 100K and 110K can be tricky on an analog device, since the Ohm scale is usually inverted, and high resistance values are close together.
Wind at the runners' backs, on the other hand, obviates that issue entirely.
Except that for the record to be accepted, start and finish of the race cannot be further apart than 50% of the total distance. That means that at least for part of the race, the wind cannot be consistently from their back (unless it happens to be turning at the right time). In that case, a strong wind is most likely a disadvantage overall.
I am currently refurbishing his multimeter - only because the sockets for the test leads have corroded, nothing wrong with the analog galvanometer itself.
Unless you want to use it to check that your 100K resistor is not a 101K resistor.
Even better than rows of dials would be a simple computer screen that would tell you only the things that are of interest to the pilot. Anything that's in the normal and expected range doesn't need to be shown constantly.
You're comparing old, high quality, analog meters with modern digital cheap shit from China. But that's not really realistic or fair. Nobody's going to manufacture a modern instrument, and install second hand analog meters. Instead, they'll order some cheap, shitty, analog dials from China, made from injection molded plastic instead of brass, and using a printed paper scale glued on by hand.
BCD makes no sense in the real world. It's much easier to process everything in binary, and only do the decimal/binary conversion at the input and output, which is going to be bandwidth-limited anyway.
many cases this adds a lot of cost for little/no added benefit
On the contrary. Precision digital equipment is usually cheaper and simpler than analog. Keeping 120dB SNR in the digital domain is trivial. In the analog domain, not so much.
Actually, the factor 25 is reasonable if you keep into account the shorter life cycle of the methane, and you want to calculate the effects over the next century. After that, the factor gets close to 1, because the methane will be converted to CO2.

I imagine it's quite hard to do a Dr Who marathon in under 2 hours.

You mean: if the Earth rotated a bit slower.

And maybe a couple of comfy seats, and a minibar.

And when they're done with the 2 hr marathon, maybe they can help these guys to design a better website.
Strange. I would expect standard double precision float to be more than sufficient for any reasonable real-world financial calculation.
Nobody cares about clock speed. People care about dollars, watts, and how quickly/accurately they get their result.

buy a used meter of the type I described

So, in your long life with analog meters, I take it there was not a single occasion where you had tap a meter with your finger to correct it ?

The kind of crap known as "significant figures".
Which don't apply here, because this is math. And even if it were a physics problem, "10" still has the same number of significant digits as "13".

A low pass filter can be made in one line of code. Not in any sense more complicated than making a good analog meter.
Sounds like a good plan. We'll be able to enjoy our free time, while our robots do all the nasty work.
Protection doesn't have to be perfect. If it can prevent most of the spread, the virus will die out.
Heh, I knew I wouldn't get a serious answer.
Most likely, that's only a temporary effect. After the gas has been used up, people will go back to burning whatever is left of the coal.
It makes sense to put it into perspective, because that "one region" is an anomaly. It's not like the whole planet is like that.
They fail to mention that "3 times" the normal atmospheric concentration is still only 0.0000054.
At what concentration would you start to worry ?

In a narrow tunnel, the train is going to act like a piston no matter what the front shape is like.
