I love Julia language for the seamless arbitrary precision math support and not much else. If we could get that in C I would be all set.

What is old is new again: https://en.wikipedia.org/wiki/S-100_bus > Power supplied on the bus is bulk unregulated +8 Volt DC and ±16 Volt DC, designed to be regulated on the cards to +5 V (used by TTL ICs), -5 V and

> And, in Julia’s defense, this is all spelled out in the documentation, immediately accessible from the REPL. I just never read it carefully enough. My concern is most physicists won't read that either and may not even notice the l

This comes up from time to time with photons. It's usually the result of confusion over the difference between phase velocity and group velocity.

General Relativity has identical solutions for forward and reverse time. The Schwarzschild metric for example is expressed in terms of time squared so time itself can take positive or negative values and give the same result. It also allows

Physics (and more generally numerical simulations) is the killer app for Julia Language. No other language makes it as easy to work with arbitrary precision math. Whatever precision you need/want, just call setprecision(), Initialize v

The ultimate example of this is solar eclipses. If you are fortunate to experience one in person, don't distract yourself with camera equipment or trying to take pics with your phone - unless you already make a living doing that. Just.

I always thought it was weird and unnecessary to use EIRP power limits on 60m vs transmitter output power (before feedline losses and antenna gain) as on every other band. The TX power limits were primarily driven by builder/operator s

NTSC colors were bad - really bad - but wideband bayer filters + sRGB are the source of the mediocre colors we see today. We could have beautiful Kodachrome quality colors If we used narrow-band RGB filters and a wide gamut (Rec.2020, or

It's tempting to blame the inexperienced first officers, their training, or the CRM failures on this flight, but the blame for this crash has to land squarely on the atrociously bad UX of the Airbus cockpit. Sensory overload and no cle
