Inevitably we’ll get to a point in which we surpass the resolution of the human eye; yes, it will be helpful to be able to have *extreme* zoom, but to our eyes the entire picture will eventually blur the lines between reality and virtuality.

What I do know is that a lot of authors have been copying each other’s references, going back more than 20 years, without ever bothering to look at the original publication.

..and that’s again another interesting observation that can also be found in some more or less obscure literature.

]]>we need to cancel all the primes in the factorization of the denominator

if one could just cancel those damned twos to begin with..

but they keep appearing

So I need 7 x 1 petabyte disks to storage that. Ok this is a mind experiment but anyhow I would love to have it like that. ]]>

exactly one ohm of resistance per foot. 30 gauge is 0.1 ohms/foot, 20 gauge 0.01 ohm/foot and so on. The exact value is 1.049 ohm/foot, but 5% is close enough. So if you’re using 14-gauge wire to run a supply, that’s roughly 0.003 ohm/foot, so 100 feet is 0.3 ohms. If you put 10A through that wire, a common household load, you’ll lose 10 * 0.3 ohm = 3 volts. The wire resistance will then lose 3 volts * 10 amps = 30 watts. ]]>
