Re: [Phys-L] charging a capacitor reversibly (or nearly so)

Cutting down on energy requirements (including cooling
requirements) is always desirable, so there is interest
in "reversible computing" aka "adiabatic computing".

This provides yet another example showing the value of
/interdisciplinary/ work. If you're going to invent
adiabatic computing, you need to know a fair bit about
the application area (chip design), and also a fair bit
of fundamental physics.

Another example of the law of small numbers. Yesterday I read Feynman’s speech transcript in which he discusses reversible computing, cooling, and micro-computers.
