DeForest had a degree in physics and didn't understand how his triode worked.

Are you sure? Was that true for all his life, or just the day of discovery? Why is that significant at all?
To solve the space charge around a heated cathode, and fields in a symmetric cylindrical-electrodes geometry, is a nontrivial problem. If you don't know how to solve a diffusion equation, and second-order differential equations, it's arguable that you don't understand how a triode works.
DeForest didn't start with a well-designed triode, just an amusing effect, worth publishing.
The patent for warp drive has already been abandoned! Definitely a potential investment opportunity here...
It's significant that he discovered the triode by fiddling with basically a flame detector in a jug. He thought that gas was the amplifying element.
JJ Thompson was deflecting electron beams with electric and magnetic fields. Others before him observed electric and magnetic deflection of "cathode rays". It seems to me that a deflection-based amplifier and oscillator should have been obvious after that. The gridded triode should have been obvious too. Maybe the scientists weren't interested in applications.
Don't be a jerk. Nobody likes a jerk.
Neither Edison nor Flaming nor DeForest did that math.
More than amusing. Worth patenting.

The applications probably weren't that obvious circa 1895; long-distance CW radio transmission hadn't been invented yet and the moving-coil loudspeaker hadn't been invented yet.
I don't think the "intellectual concept" of voltage/current/power amplification was well-understood at that time it's hard to invent something to do something when you don't even know what you're looking for it to do.
It wasn't until the early 1920s apparently, what like 40 years after the invention of the dynamic microphone when they figured out "oh you can use the same principle and run this deal backwards with power amplification and produce sound as well as transmit it"

Super smart people I admire have met with Trump privately. They were blown away. They say the man's brilliant.
I'm amazed at the level of his opposition's ignorance. PBS' Newshour's Mark Shields and David Gergen, for example.
Easing obnoxious regs and lowering the marginal corporate tax rate have re-ignited half the country (or more).
Cheers, James Arthur
I wasn't being a jerk, I was asking what the sphinx-like phrase "didn't understand" referred to. Thanks for the clarification, jerk.
By the way, gas IS a kind of amplifying element in breakdown, that's why neon lamps make such good surge protectors. A gas-amplifier model wasn't far wrong. Trigger electrodes in a thyratron make a kind of triode based on that principle.
You've got to be seriously dim to think that. Trump is on Trump's side, and nobody else's. He'll say anything to get people on his side, but he's been a serial liar all his life, and you have to be as dim as John Larkin to be unaware of this.
They does include quite a few of the people who keep society running, but the college indoctrinated folk play their part in that as well.
Growing the food that you eat is part of the process of getting it onto your plate. John Larkin has enough sense to realise that if it isn't grown in the first place it won't get onto his plate, but has no idea how complicated the rest of the process is.
The Senate was a good idea - not original, but good. Subsequent constitutions have copied it. The Electoral College was a bad idea, and nobody has copied it. Minority presidents have been fortunately rare, and remarkably unimpressive. Trump is a particularly depressive example.
Depends on the unorthodox idea. Continental drift was unorthodox when Alfred Wegener championed it in 1912, but when the evidence for it started to accumulate it finally made it.
The idea that stomach ulcers were caused Helicobacter pylori bacteria in the stomach was equally unorthodox, but had better evidence and got adopted \very rapidly.
Most genuinely new ideas are genuinely bad idea, and need to be suppressed.
Max Planck didn't much like the content of Einstein's four 1904 papers, but he really liked the quality, and didn't bother getting them peer-reviewed before publishing them.
John Larkin hasn't got a clue about observational science. The observations required to validate continental drift took a long time to accumulate, but once they'd got published the theory got to be very respectable.
The nice thing about experimental science is that you can choose what to observe when you want to observe it. Quite a few sciences don't have this luxury.

She won the popular vote handily, by about three millions votes. The Russia n intervention was concentrated on what turned out to be the three crucial states, where Trump's winning margin was some 70,000.
He hasn't got enough sense - nor a long enough attention span - to listen t o expert advice. He may have a will to win, but doesn't know enough about w hat he's doing to translate that into effective action.
So far he's been lucky enough to get away it.
Betting the long term future of your country on him isn't exactly clever.

Everything is obvious after somebody has explained it. In patent law the dictum is that everything is obvious to the Supreme Court, because all teh explanation have been refined in the lower courts.
John Larkin knows all about that
Edison certainly hired mathematicians to do that kind of stuff for him. He had that kind of money.
If people skilled in the art don't find an idea obvious, it's worth patenting.
One of my three patents looked perfectly obvious to me, but after I'd had to explain why it was obvious a couple of times I realised that I'd better put in a patent query.
Inventors - and De Forest was definitely an inventor - are rather more enthusiastic.

Read "Shattered." Great fun. Bill did warn them - WJC has political instincts, like DJT - but they were too smart to listen.

Yeah, if you come here and sit on a bar stool, you'll also find a good dose of racism. (I'm thinking NFL at the moment. blacks who earn a lot of money are hated.) T knows just how to tweak his base. Rather than being presidential, we now have reality TV Prez. (live in T's reality, or else.) I'm mostly fear we'll have another four. Amy K. my only hope.
I'm mostly disappointed in the Senate, they've been breaking their old rules (filibuster-wise) for a while now. (both sides) And I fear it will continue.
I heard from someone (Pogo :^) that because we don't have an outside enemy, we are fighting ourselves.
Yeah, I heard a suggestion it might be better with one editor... but still anyone with a stick in the game will have some vested interest. (I'm re-reading this short bio of Newton... wars with Hooke.. He (Newton) mostly just kept his ideas to himself.
My laser diodes came in today. These things are tiny! How big is the output facet? (Tiny is good!) If this works I'm going to want little fiber coupled PD's (and fast!) I've got these photo diodes that look huge in comparison.. BPW34 (I think I can tape 'em off to make the optical size smaller. (there will be a little shadow effect on the sides) There're some parts of optics... maybe a large part.. that I don't understand so well. George H.
Good grief, force yourself to read the Sunday New York Times. It's all Trump, Race, Trump, Global Warming, Trump, and Trump.
The small biz tax cuts will pay off bigly, but slowly.

I think that's mostly undecidable. Nothing in his communication style is designed to expose actual information. It's more like sleight-of-hand.
Perhaps you'd have had to see this in real life for it to make sense? It's schematically described in David Mamet's "Glengarry Glen Ross", in an intentionally obscure manner.
I've worked for a couple guys like that.
There is no puppeteer.
Of course we do - it has massive efficiencies at a cost in information loss.

Trump is loved here. I've never seen anything like it. (I'm ~60) I see no such enthusiasm on the left. And much as I like Joe Rogan, if Bernie was the D nominee.. I'd be hard pressed to vote for either he or T.
I try to listen to as little news as possible. Sports and weather are OK. Except for my below average hockey team.
Yeah more deficit spending. If you can borrow at ~zero interest it seems silly not to... but it's not what I would do.
