Follow car terminology and be done with it. Also follows marking of all bike shifters.
Full range achieved, going from fastest to slowest works (downshift), but going from slowest to next slowest (upshift) fails. Limits are good, B-tension screw didn't help
- bicycles.stackexchange.com/questions/66811/rear-derailleur-does-not-downshift-properly-shifts-up-smoothly likely good question but with wrong up vs down terminology
It is true, something Ciro Santilli often things about. One likely reason is that the world is broken and most cyclist are speed maniacs willing to put the time in. Unlike Dutch people where everyone cycles.
The images you have to have in mind are:
Yes, Sheldon he has separate American and British English versions of pages!!!
For example, Kross bicycle (2017) had a Schwalbe tyre with markings:When inflated, the tires were about 3.5cm wide as measured with a ruler.
42-622 (28 x 1.60, 700x40C)
And the Mavic A319 rim had markings:
622x19C
In this:
- ISO (Etrto): 42-622. So:
- 42 is the inner rim width. The actual inflated tire is going to be even wider.
- 622 is the bead seat diameter. The actual inflated tire is going to be even wider.
- imperial: 28 x 1.60
- French: 700x40C:
- meaning of the "C" asked at: bicycles.stackexchange.com/questions/16190/what-does-the-c-in-bicycle-tire-size-mean
- www.sheldonbrown.com/tire-sizing.html#french says A is larger than B which is larger than C, and C means 622 mm

What Elon Musk's 42,000 Satellites Could Do To Earth by Tech Insider (2020)
Source. Good primer. The main difference from older systems is that they fly closer to Earth, and are not geostationary. As a result, you have better latency. But you also need a bunc of them to have continuous coverage of an area.They actually carry atomic clocks in them.

- too much local power
- republican/democrat partition means federal projects start in one government, get killed on next
