If you're sending over a single channel (telephone audio, or a radio link, or an optical fibre), then bits/s are natural.
In the simplest cases you send one bit at a time

The early 4004 and 4040 microprocessors were 4 bit devices, so no nibbles were natural there

Also one transition can carry >1 bit. With 4 amplitude levels 1 baud is 2 bits/s.

Claire - if you have a 200mV or better DC range on your multimeter - remember PCB tracks have non-zero resistance. Measure the drop from +5 input along the tracks to see who's drawing all the current...
(Clearly also applies to ground, but harder with a decent ground plane)

Gebco is great - low res, but world-wide. Oh, and it also covers land!
In shallow water keep an eye on vertical datum - different sources used various - and I don't think GEBCO has yet unified them.

There are a few bits of CS that are worth studying (data structures, algorithms and complexity, some of OO) for scientific computing
AFAIK they are also possible to study outside a degree program. Your student need not worry - just read good code and ask "how and why"?

We need expensive, unpopular long-term world-wide actions. That requires a world government with a powerful army and no electors.

Just check that no tasks (e.g firefighting, veh maintenance) require you to be 6 ft tall and 200+lbs - if not then an all-female crew could work. (If so, then recruit some big lassies before you kick us out)
