What does that even mean? And why does TMQ feel compelled to start off with horse racing metaphors?
After the jump, this week’s TMQ (which you won’t be able to read in its entirety unless you subscribe to “All Predictions Wrong”, which is the actual title of Gregg Easterbrook’s Substack)…
(Also, if you feel like it, I’d encourage you to throw a few dollars at Damn Interesting. They’ve missed their goals for the past couple of months and I’m a little worried about the continuing viability of the site.)
The bomber seems fairly clever. But not clever enough: they got DNA, they got location data from his cellphone, and they got video from a neighbor’s doorbell camera.
I hate to link to Crimereads two days in a row, but this is another one of those articles I feel like I have to link. Especially since it lets me tick off multiple categories from my list:
According to reports, none of the injuries are “life-threatening”.
FotB RoadRich can correct me if I’m wrong, but I have a memory of APD’s bomb squad telling us (when we were going through the Citizen’s Police Academy) that the most dangerous thing a bomb squad does is…disposal of fireworks. I don’t know if that’s because they do more fireworks disposal than anything else, because people get blasé around them (“It’s just fireworks!”), or if because fireworks are more volatile than anything else they deal with.
Edited to add: Lawrence sent over this tweet from CBS LA: their helicopter was directly overhead when…
WATCH: Sky9 was overhead when police attempted to detonate a stash of illegal fireworks that ended in an explosion in the 700 block of East 27th Street in South L.A. https://t.co/KpWiAEoyqvpic.twitter.com/UbIXLDoZjh
His family owned the Champion Spark Plug company, so he had family money. He got a PhD in physics, and spent a lot of time doing physics in the late 1950s.
Going back for a minute, if the Woody Creek Tavern rings a bell with you, yes, that was Hunter S. Thompson’s hangout. Mr. Stranahan and Hunter were close friends.
This is also the last entry in MilHisMon. Sort of. It’s complicated.
Somewhere in my collection of books on leadership, I have a thin little pamphlet that I picked up at the National Museum of the Pacific War: “Arleigh Burke on Leadership”.
“Saluting Admiral Arleigh Burke”, circa about 1961 (around the time he retired, after three terms as Chief of Naval Operations).
Bonus #1: This might be the last chance I get to do one of these. Plus: CanCon!
“Canadair CF-104 Starfighter”.
Bonus #2: And as long as I’m taking last chances…”Secrets of the F-14 Tomcat: Inflight Refueling” from Ward Carroll.
As a side note, which I learned from Mr. Carroll this past weekend, did not know previously, and don’t really have a good place to stick it: one of Donald Trump’s final pardons was granted to Randall “Duke” Cunningham.
Bonus #3: A documentary about “Operation Blowdown”.
“Operation Blowdown”? Yes: back in 1963, the Australian military decided to simulate a nuclear blast in a rain forest, just to see what conditions would be like afterwards. Because, you know, why the heck not?
A device containing was detonated to partially simulate a ten kiloton air burst in the Iron Range jungle. The explosives were sourced from obsolete artillery shells and placed in a tower 42 metres (138 ft) above ground level and 21 metres (69 ft) above the rainforest canopy. After the explosion, troops were moved through the area (which was now covered in up to a metre of leaf litter), to test their ability to transit across the debris. In addition, obsolete vehicles and equipment left near the centre of the explosion were destroyed.
There’s someone on the ‘Tube who has a channel, “Demolition Dave Drilling and Blasting”. I think he’s ‘stralian, mate.
In this video, Dave reviews a Chinese generator.
How do you say “Harbor Freight” in Australian?
Mike the Musicologist sent me this: it is a little more recent than I’d like, and I think I’ve seen it linked on Hacker News, but I still think it’s worth highlighting here.
“What Really Happened at the Oroville Dam Spillway?” from Practical Engineering.
Finally, here’s something that’s just about 25 minutes long, and that I think some folks will enjoy: “The Unfortunate History of the AMC Pacer”.
“There’s a fine line between uniqueness and strange.”
There have been a couple of incidents recently involving old guysfalling off boats into the water and dying.
I’m not making fun of them: mad props to these guys for being out there. But, as Lawrence put it: “Important safety tip: try not to fall off the boat.”
From the National Safety Council, circa 1972: “Find a Float”.
Bonus #1: in honor of the late Bobby Unser, “Hazards of Mountain Driving”.
Bonus #2: “Blasting Cap Danger” brought to you by the “Institute of Makers of Explosives” circa 1957.
I remember when I was young and reading “Boy’s Life”, every now and then they’d have a public service advertisement depicting various types of blasting caps and warning young Boy Scouts not to mess with them. My question was: why? Was there a real problem with people just leaving blasting caps lying around for kids to find?
I was hoping to find some good Pi related videos on YouTube. Instead, I turned up a lot of crap about something called “Pi Coin”, which sounds to me like a scam cryptocurrency. (Is “scam cryptocurrency” redundant? In any case, I’m putting my money into DogeCoin.)
I thought about posting some pie related videos, but I can’t quite stretch my definition of science that far.
So maybe a grab bag of science randomness?
“I Make Guncotton (Nitrocellulose) With Hardware Store Ingredients, Again.” Never know when this might come in handy.
Bonus #1: “The Rocket: Solid and Liquid Propellant Motors”. Vintage 1947, and a nice explanation of how solid and liquid propellant rockets work.
Bonus #2: This is a little on the darker side, but I feel like there’s at least one person (besides me) who might find it interesting: “A History of Nerve Agents” with Dan Kaszeta, the author of Toxic: A History of Nerve Agents, from Nazi Germany to Putin’s Russia (affiliate link, but since this is from Oxford University Press, it’s a bit on the pricy side).
