How does magnet fishing work?
You can always trust the Republican candidate to be wrong on all matters of science. Now Trump is opining on magnets. It’s all part of his long history of complaining about magnetic elevators and electronic catapults on aircraft carriers, and it’s just plain stupid.
This guy is the leading Republican candidate. He’s an idiot.
I’m not sure what the “SSAT” label means but I think it’s “Serial sex abuser Trump”?
“This guy is the leading Republican candidate.” He’s just one of many Republican idiots (and a few Democrats as well), not to mention the people who vote for these con men. Apparently Mike Johnson, who just happens to be third in line to the presidency, talks with God regularly and God told him he’s the new Moses. That’s very scary.
I couldn’t even tell WTF he was blathering about. A billion dollar cost overrun on some “magnetic elevators?” What elevators? Where? Is he referencing something in reality, or is it just the worms in his brain pooping out word salad like usual?
And if Biden said those exact words? The press would be all over it like flies on shit. Why does Grump get free idiot passes?
WHAT???
Artor @ #2 — I think it’s in part about this: Electromagnetic catapult. That’s an upgrade to the steam catapults used on aircraft carriers for decades. But as usual, the words spewing from his mouth are a mash up of disparate hobbyhorses as his thoughts bounce around the pinball machine of his brain. Ding ding ding-a-ling.
Artor, he’s blathering about the USS Ford, which uses magnetic elevators, arresting system and elevators. Currently deployed in the Mediterranean monitoring the wars in Gaza, Syria and Iraq. Apparently, Scotty is beaming the warplanes into the air using Harry Potter’s magic wand, since magnets dissolve in water or something.
And those thrusters on various ships, including cruise ships dissolved, compasses for divers and ancient sailors never worked and aw, screw it, he’s good with science because he has an uncle that is a physics professor.
He’s also the same shit for brains that griped about the the Ford while in office, demanding it be fully converted to steam – which would require it to be entirely disassembled, redesigned to install new steam plumbing and well, a steam plant and basically was as brilliant an idea as his brainstorm of nuking a hurricane away.
redwood @ 3, that’s easy. Trump is the god-emperor, so he always gets a free pass, lest he smite someone or something. Or a follower shoot up some press office…
Personally, at his next speaking engagement, I’ll happily bring a bucket of water and cobalt magnets and invite him to to end those magnets. No, I’d better not, I’d probably hit him with the full bucket.
Don’t forget that he’s also the same asswipe that said that, once in office, Biden would hurt god.
Agree, it’s about aircraft carrier launch systems. He prefers the older steam catapult systems since the electromagnetic ones are too complex. In 2017, he said ‘You have to be Albert Einstein to figure it out’.
Since like Einstein he’s a genius…I mean he said so…shouldn’t he be able to figure out these electromagnetic catapults, elevators, and arresting systems? It’s not rocket surgery after all.
Half of the people getting ready to vote for him know that he’s an idiot, a liar, a crook and a fucking liability but they’re going to vote for him anyway, and the other half are deeply impressed by his intellect.
Remember all those warnings about how AI is going to create deepfakes so realistic that we won’t know what’s what? Well, let them try to out-weird this.
Wow, Trump is really going downhill fast, or something.
I remember the 2016 campaign. Hillary’s technical staff had wiped a hard drive (with court approval) using software called BitBleach. In Trump’s short-circuited brain, this became actual bleach. They had dumped the hard drive into a bucket of actual bleach. And then, that wasn’t weird enough. He transformed the bleach into acid, and started saying that they had acid-washed the hard drive.
So Trump’s mastery of technology is not a new thing.
Link, in case you too were busy doing acid in 2016
So, no rail guns for Trump supporters.
Invisible airplanes.
Ummm…what?
I vaguely remember the controversy over electromagnentic catapults on aircraft carriers. I looked it up for the latest.
The steam catapults work but they have their problems as well. It takes something like a quarter of the aircraft crew to run them.
The EM catapults work and they are getting better with time. Slowly.
It doesn’t seem to seriously interfere with the aircraft carrier’s functioning.
The Electromagnetic refers to the type of electric motor that is used to drive the catapult carrier. “The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft.[6][7] ” It isn’t magnets per se but an electric motor that drives the catapult system.
Trump is a magnet for “stupid”, so maybe he should be totally submerged in water for an hour or two?
Reginald Selkirk @ 11, I never figured out why Hillary’s people used that crap, when there was a US government approved wiping software package that was entirely open source and highly effective.
Although, in the end, they ended up having to scrap the drives via the NSA, due to the sheer volume of partial spills of classified content. Clearing mail servers of that mess is a bit of a pain – I’ve had to handle that personally. Have to exmerge it out, purge the data store, restore the data minus purged class, overwrite free space, royal pain. The base I was on when handling it personally averaged one spill per year, which actually was exceptionally low.
Later, if a drive had classified on it, the platters or entire drive was sent to the NSA for literal shredding and disposal. That remains in force today.
raven @ 15, I’ve worked with linear induction motors in the past – high precision versions. When scaling them up like for a catapult, switching timing and hysteresis interactions become problematic and reliability isn’t usually mechanical, it’s switching related, as snubbing counter-EMF in such circuits becomes a lot tricky, due to the variable pulse switching – plus we use an AC system (China’s using a DC system). Personally, I’d have gone with a DC system, lowering some efficiency in favor of simplified filtering, save for that introducing a major operational issue that’d make the entire vessel vulnerable to an entire rather old class of weapons trigger system. With an expensive, but easily implemented counter. All of which is classified, so I’ll not discuss it.
The arresting system, as far as I’ve heard mostly had electromechanical issues, which are eventually simple enough to tame.
Detractors really hate it when I pull out the history of steam catapult systems, as early ones were only partial and for light aircraft – heavy aircraft needed the entire flight deck to rolling takeoff under exclusively their own power and were even less reliable. They were, after all, using live high pressure steam – in an era that finally had tamed boiler explosions – barely.
The irony here being, I know a rather fair amount about these naval systems and I was an old Army knuckle dragger. That was and am still a CET and now, IA type. Starting out working with nuclear weapon hydro-pneumatic and electronics systems.
So, I know enough about live steam to stay the hell away from those systems. And have witnessed with high pressure gas leaks can do to a human body.
The issue with steam is, light aircraft and drones can’t be launched by steam cats, they’ll literally be shredded by the acceleration. The EM cats can and do launch both heavy and extremely light aircraft quite handily.
And being new, like anything else novel, has tons of growing pains. How many Naval railguns do we currently have deployed again? Zero being the number, for the rails wear out after only a few shots.
The new Chinese aircraft carriers have big problems with electromagnetic catapults. Their tech does not seem mature.
Robro @ 1, yes, I learned that from Mano Singham.
We need an abbreviation that also include “narcissist”, “compulsive liar” and “challenged”.
Boris Johnson is also an idiot, but as he was successfully taught some social skills he can mostly hide it.
The same can be said about Liz Truss (she was within hours of collapsing the British economy, when the central bank intervwned).
The new guy in Argentina – the one with the chain saw- may yet turn up to be in a category of his own.
I am told catapults wear out plane fuselages because there are big forces concentrated in a tiny spot. I assume the planes consume far more spare parts than USAF planes.
By contrast, the Sea Harrier was self-catapulting, rolling up an inclined ramp and switching to vectored thrust the moment they rolled over the edge, with the weight shared between wings and jet. The wear and tear was on the undercarriage springs.
I have an idea: let Trump bring a glass of water and stand near a MRI machine… while holding scissors. That will be quite safe as the water will negate the magnets.
Isn’t the real risk with these catapults the problem that all the crew is magnetic now after their covid vaccinations?
@1. robro : “I’m not sure what the “SSAT” label means but I think it’s “Serial sex abuser Trump”?
Yes. Mano Singham has invented and / or uses that acronymn for Trump a lot.
I wonder if supposed stable genius Trump has ever read about the magnietic fields of Ouranos and Neptune?
Source : https://en.wikipedia.org/wiki/Ice_giant#Magnetic_fields
Emphasis added.
@22 “I wonder if supposed stable genius Trump has ever read” there, fixed and shortened that for you. It is clear that he has never read a book in his life, except, possibly, a selection of Hitler’s speeches as a working manual.
Bcw bcw@ 21
Let them have small wings attached to their shoulders and you can launch them in the air, like 1940s superheroes.
😊
Idea:
If you are expecting thunderstorms, tell Trump he will be safe from lightning if he stands on some thick rubber object, like a car tyre lying on the ground.
–Explain to him it is the insulation of the rubber tyres that make cars safe during thunderstorms.
In fact, encourage him to stand on a mountaintop to watch the view of the lightnings, as long as he is wearing rubber boots or something.
He will buy it like a MAGA follower buying a Trump action figure.
bcw bcw @ 21, no, obviously Trump is now working for THEM, for those EM catapults would obviously erase their COVID-19 chipset. Hence, why he remains against them and dismisses the magic of magnets.
nomdeplume @ 23, what amazes me is how far he got into the book of Hitler’s speeches, as to my knowledge, no such book exists that has pictures and bulletpoints.
wzrd1, um, Stephen Miller is the speechificator for SSAT.
(Credit where credit is due)
@26 they all have bullet points….
@6. wzrd1 :
Objects being beamed Trek~style are usually stationary aen’t they?* I guess they can turn engines on and attain flight velocity speeds mid-air..
I presume the USS Ford is named after the former POTUS and not Henry of the model T.. Checks :
https://en.wikipedia.org/wiki/USS_Gerald_R._Ford
Yup. Natch.
Oh and, of course, thinking naval what about magnetic mines and weren’t / aren’t some torpedoes magnetically guided?
Albeit sometimes with some issues as Drachinifel
expalins for the mark 14 here ( https://en.wikipedia.org/wiki/Mark_14_torpedo )
Or are they? What happens if you sneeze or move or wave or something mid transport?
@ 23. nomdeplume : Yup! Good point. ^Another asterisk eaten here I see..
@27.nomdeplume, #26.John Morales, #25. wzrd1 : Maybe Stephen Miller or Steve Bannon, Trump’s klansman father* or someone else read those Hitler speeches to Trump as his bedtime story?

Except Fred Trump was there and was arrested so that’s something even if, yeah, unclear. You could argue that Trump and his subsequent conduct and comments are kinda indicative though circumstantial evidence here and I note we don’t see any evidence of Trump Sr opposing the Klan here either. Certainly Trump seems to parrot some pretty racist things and regard White Syupremacists in an unduly favourable light. (Understatement.)

@birgerjohansson, # 20: It would still be unsafe. Trump run with the scissors, in spite of all the safety warnings not to.
StevoR, get with it.
No. Never.
Also, “beamed” means they are disassembled into their constituent parts and then sent technomagically to a receiver where they are either stored in a buffer until they are reassembled, not that they are sent whole in some sort of carrier beam.
This is all canon. Stupid, but that is what it is.
See, molecules — never mind atoms — are never still, never mind relativity.
Please remember Star Trek is not science fiction, it’s speculative fantasy, it makes no sense internally nor does it correspond to reality either scientifically or historically.
Remember the Eugenics Wars that started in 1992?
(Me neither)
You are positively Trumpian in your grasp of tech.
(Or, by trying to mock him in this way, you are revealing you are just like him. The irony obs escapes you)
Perhaps refer to Einstein’s theories. Or even to mere Brownian motion.
Motion is relative, nothing is static except in reference to itself.
Over the decades I have come close to doing my body weigh in Hallucinogens and never in that time did I mouth something that profoundly weird and wrong.
“Say what you will about the tennets of national socialism but at least it’s an ethos”
StevoR @ 28, the guidance wasn’t magnetic, it was gyroscopically guided, the warhead was detonated magnetically or on contact, but the goal was to use a smaller warhead that’d detonate under the keel. That technique is still used today, albeit with slightly different methodology, due to the far more common practice of ship degaussing. And yeah, the mark 14 was a mess when introduced, took a couple of years for BuOrd to even admit there was a problem, despite the Navy demanding the problems be fixed (such as the magnetic detonator usually didn’t work, save against the launching submarine in at least one case and the contact detonator worked great at 30 knots, broke completely at 46 knots).
Wikipedia has a wonderful article, complete with a shot of the only live fire test of the mark 14, whose first shot happily sailed beneath the target vessel and failed to explode.
Current torpedo guidance is dependent upon the target, so it can be wake homing for surface vessels, acoustic characteristic homing, passive sonar homing or active sonar homing. Again, magnetic homing ain’t in the cards, due to a ship’s magnetic field being quite weak (the early magnetic detonators relied on a difference in field characteristics introduced by the ship being from a different magnetic region, hence having a significantly different field strength than the local environment), more modern types more rely upon higher frequency influence circuitry and other characteristics to determine when the torpedo is beneath a vessel’s keel.
Obviously, keeping the physics down to a minimum, there’s tons of math behind the entire concept.
The failures of the mark 14 were epic though, some shattering quite loudly against Japanese hulls, which obviously attracted some ire toward the launching submarine, blithely sailing beneath the target’s keel, circling unexpectedly back at the launching submarine. Once BuOrd finally admitted there was a problem and finally fixing the damned things, they were phenomenally effective at sinking Japanese vessels, rather than US launching submarines. But, they most certainly did contribute to new submarine sales early on in their career.
Maybe SSAT means surrogate SAT, as we learned from his sister.

birger, just in case you care, be aware that YouTube links specify the video ID with the
v=parameter.Everything else is irrelevant for your purposes. In short, you can strip all that stuff with no loss of sharing functionality, other than for Alphabet (Google’s parent company).
That is, the
&separator allows for other parameters, in this case (@36) information about you and how you got the link. The equals sign in each case specifies the particular parameter type. I’ve noticed you never try to strip all that gunk from links you provide.Basically,
si=identifies stuff about the sharer for analytic purposes — it encodes who, from which page, and how the link was shared. Not that important for readers here, is it?@32. John Morales :
Canon? Huh,. I thought this was canon?
Well, Pachbel’s version of it anyhow..
Yeah, the Trek verse technobabble is that.. The Heisenberg Compensators work very well thankyou but questions still arise..
Ouch. Still I know I’m way out of my jursidiction here and working off vague & fallible memories. Hence my question marks. I mean it ain’t rocket science or local (Mt Lofty Ranges / Adelaide Hills native flora so..) yeah. Or star names ..or 1980’s SF TV cartoons & series so..
