#5958: The old and the new

Og stopped by to assist me with a little project, so I had him snap this for me:



Which is the 2017 version of this photo from 1972:



...and damn it, we forgot to close the garage door first. Oh well. It's something I've wanted to do for months and finally got done!

So, let's talk about what happened down in Texas yesterday.

The leftists can't wait to dance in the blood of the victims. But of course the leftists remain silent on the carnage in Chicago (due to gangs) that racks up such huge body counts weekly. (And incidentally, 96% of all crimes in NYC is committed by blacks and hispanics. Go figure.)

And as usual the left's compassion is reserved only for its adherents, not anyone else. Example: "let's face it: we're glad it wasn't educated people we care about who got killed. these are Trump voters, fuck 'em," tweeted one paragon of leftism. As Porretto observes:
These are people who utterly lack empathy--what Adam Smith called "fellow-feeling." Yet they say we in the Right are "uncompassionate." They're perfectly happy with the murders of those who disagree with them politically. Yet they call us "fascists." They seek to confiscate our instruments of self-defense and grant the government a monopoly of all weapons. Yet they accuse us of "paranoia." They have made politically founded hatred into their religion. Yet they call us "haters," and our contrary opinions "hate speech."
It's all the left has. What do you expect?

Ultimately, though, it turns out that the shooter had been either been dishonorably discharged, or received a "bad conduct" discharge, from the Air Force. Depending on which it is, and the circumstances of his discharge (for domestic violence) such would automatically bar him from legal ownership purchase of firearms. (Even in Texas.) He was an atheist.

And he was stopped by a citizen with a legally-owned firearm. As soon as someone showed up with a gun to stop him, the shooter turned tail and ran.

Speaking of pusillanimity, we have the NFL. NFL is stepping on its own dick with this "take a knee" crap, and instead of fixing the situation they took their foot off their dick long enough to put on their cleats and stomp extra-hard on it.

Oh well.

Science!

Quark fusion is energetic stuff. In my SF world there are things called "subnucleon weapons" which are basically bombs that generate a quark-gluon plasma. The plasma is only briefly confined--a few nanoseconds, while the detonation completes itself--and then it explodes. Okay, imagine what kind of damage would be done by about a kilogram of gas at a temperature of 7,000,000,000,000°F. I'm a bit rusty on the whole "gas law" thing but allowing that plasma to escape will result in a very hot and fast shockwave. Naturally it will cool as it expands, but as it cools suddenly the quarks and gluons are coalescing into fast-moving particles, and now you've got to deal with heavy ionizing radiation....

Main point: not a good idea to be in the neighborhood when one of those things goes off.

The idea of subnucleon fusion (ie quark fusion) had not occurred to me. That it's many orders of magnitude more energetic than nuclear fusion does not surprise me. Ditto for the fact that it's many of orders of magnitude more difficult.

And VLF radio is fascinating.
We live in an electromagnetic soup, bombarded by wavelengths from DC to daylight and beyond. A lot of it is of our own making, especially further up the spectrum where wavelengths are short enough for the bandwidth needed for things like WiFi and cell phones. But long before humans figured out how to make their own electromagnetic ripples, the Earth was singing songs at the low end of the spectrum. The very low frequency (VLF) band abounds with interesting natural emissions, and listening to these Earth sounds can be quite a treat.
In that Hackaday post there's a video which is worth watching, because among other things it talks about the VLF signal which inadvertently ended up embedded in Tubular Bells. With the right software, you can actually extract Morse Code transmitted from a VLF station at the time the studio recording was done. Which is damned cool.

The propagation of RF is essentially black magic, anyway. Earth is a giant electromagnet, with a dynamo spinning in its core to generate a pretty strong magnetic field, and that magnetic field interacts with our Sun's magnetic field in weird ways. The result is variations in how radio signals propagate depending on whether it's night or day, and a lot of other stuff.

If you click on one link in that article, click on the one saying "very much like its avian namesake", and listen to it. That's the radio sound of a sunrise.

We live in an incredible world.

Well, I've got lots to do, so I'd better get back to it.
