BTW, I'd really like to know why the Debian people decided to rename NodeJS to just Node. It took me quite a while to figure out why NodeJS didn't exist after having installed the package. Renaming the main executable for no damn reason will do that!
The Node.js folks also call the executable node, so, um, maybe they use Debian too?
Newton didn't get the energy part.
Einstein (as I understand it) and the rest of the physics world had a problem in that Maxwell's Equations did a really good job of describing electromagnetism. However, the wave equation that pops out does not account for the velocity of the observer. This implied that the speed of EM radiation (light) is constant for ANY observer: oh dear. Einstein (and Lorentz) hypothesized that time didn't have to be the same everywhere, and came up with Special Relativity to describe it. And, remarkably, SR was shown to be accurate. It's also how energy gets mixed in with mass.
A handful (nearly two hands full) of years later, Einstein published General Relativity as a description of why acceleration looks the same as gravity. (Inspired by Newton's F=(constant)*Ma=GMm/(rr).) He did this by hypothesizing that distance is not the same everywhere. And, remarkably, GR was shown to be accurate. (He needed some help from other mathematicians, because the math is hard for warped spacetime.)
Maybe the above is not quite kid-friendly, but Einstein challenged the ideas of classical physics (time and space being "flat"), and got it right. Or at least the next-level-of-right.
I bought gold-plated optical cables at Fry's last week. It was the cheapest option. And, yes, there really was a tiny gold-colored ferule around the fiber. I'm sure the photons are much happier and crisper now.
I was testing some components (class D amplifier) and wanted a quick signal source, so I hooked up my phone. I was quite surprised (and concerned) to discover that my LG G6 is pumping out a VERY LOUD signal at 50kHz. I can't hear that high (I stop at about 12kHz now), and earbuds will attenuate it quite a bit, but I imagine it could still cause hearing loss. (BTW, I was looking for ~250kHz noise in the amplifier, but that component was attenuating correctly. It faithfully reproduced the 50kHz whine, however.)
I won't be listening to music on this phone... now I have to test my other phones.
