    Percy might have technically surpassed Edison for patents, Edison had a league of inventors working for him, Edison took full credit for any work done thru his minions, Mr.spencer, one man show! The Westinghouse documentary disects the topic thourouly, very well done, worthwhile watch.

      Right Edison refused to pay tesla the promised bonus for inventing the A/C electric motor so he left and got the financing from Westinghouse to build the power plant in Niagara New York

      From what I understand Edison was an inventor of some renown but he, as already said, claimed his employees inventions as his own, but also claimed other inventors inventions as his by filling patents before the original inventor could thus claiming as his own, I am not aware how true or untrue that is but I did see it in a documentary about inventors and their inventions, I also understand that it is entirely possible that two independent inventors could and have come up with a solution to a problem but with slightly different results that they would have to argue about who got there first, Edison and Tesla.

    16:30 I believe Zuse's relays came from telephone exchanges rather than telephones themselves. Telephones didn't necessarily contain relays, even if one did, there would likely one be one. Telephone exchange switching equipment, on the other hand, would use hundreds and thousands, more even, depending on just how big the exchange was and how many customers it served.
    Secondly it wasn't an end to moving parts. Relays are moving parts! A relay is a mechanical switch, just like, say, a light switch. Except instead of being operated by a person's finger, an electromagnet pulls on a lever that opens or closes switch contacts. Those switches can then be connected to other components, including more relays! So you can have relays turning each other on and off. Just like the transistors in a modern computer, except those transistors are extremely microscopic, where even a small relay would take a few cubic centimetres of space, larger ones taking cubic inches.
    Relays will have made Zuse's later machines, the Z2 and Z3, more accurate, but more because each relay was itself a well-made, reliable component, made so to the demands of telephone companies, who demanded high standards of reliability.
    They, erm, likely didn't hum either! This part got the most basic facts about Zuse changing from mechanisms to relays correct, but the rest I think are conclusions jumped to by the documentary maker or script writer. They're not accurate. Sure, I don't expect everyone to know the working principles of relays, but they probably should look it up if they're gonna do a documentary feature with them.
    Relays are still used nowadays, btw. Not to compute with, but where you want a smaller, less-powerful circuit to be able to control a more-powerful one. The smaller circuit energises the electromagnet, and the powerful part, perhaps a big motor or heater, is switched from large moving contacts.
    Last thing - Zuse didn't invent binary or binary logic. George Boole, an English mathematician, did, in the 1840s. At least he's thought to be the modern-day inventor. It could have been invented in the past prior to that, it's a subject I haven't researched enough into to speak with authority. Regardless though, it certainly wasn't Zuse.
    Zuse is well-known as part of the history of computing, along with Charles Babbage and Ada Lovelace. He's perhaps not as well-known to the public as some others. So it's nice to mention him, just a shame this video got him completely utterly wrong! If whoever made it has ambitions, they might consider doing that part over again. It would only require re-doing the narration I think, the existing video you could keep.

    The thing about Edison is that he claimed all the pattens made by his associates who worked under him. It is doubtful he made all those inventions himself.

    • @darz3829
      @darz3829 Рік тому +3

      Just as major corporations do today, someone like Edison comes up with an idea and assigns the grunt work to machinists and engineers. And just like today, Edison had the PATENTS filed under his name (sometimes along with those who worked on it). The important part of inventing is making money from an idea - Edison's crew didn't know how to do that. BTW, Nichola Tesla worked for him and eventually died in poverty despite his genius.

    Why is the narrative only a short after thought. I have to go play pause play pause. and the timing of the narrative is completely different than the movie. Is the narrative different than the movie? I'm not sure since the timing between the narrative and the movie is completely offset. I think they are the same just not sure. Also the narrative shows for about 1/2 second and the talking is much longer. Clean this up and re-organize to narrative timing and lengthen the time the narrative is shown. The written dialog is mostly not repeat not the same as the audio??????? Has anyone else figured this out????? Thank you.

      No, I once had a junior engineering technician with a degree in mechanical engineering working for me, but what he had in his head never translated into his hands, I left school with virtually no educational certificates, but I still made the big bucks, but I always felt that the big bosses would rather listen to degree boy than hard worked experience man, so I definitely think the answer is no.

    As usual; American video, collars as much glory for Americans as possible. Re. radar (a BRITISH invention), and microwave ovens. What made airborne, long range, high definition radar possible was our invention of the cavity magnetron in 1940, which made centimetric radar possible, with antennas short enough that you could fit them into an aircraft as small as a Beaufighter or Mosquito (as we did by early 1941). The cavity magnetron was also capable of FAR higher power outputs than its predecessor, the klystron. And you know what adds insult to injury? The fact that the British government GAVE you lot ALL the info and design data for the cavity magnetron in the autumn of 1940 for NOTHING!! (along with all our research on atomic fission and the proximity fuse for anti-aircraft shells) Yet in this video, none of that gets a mention.
    At the end of WWII, an internationally respected American military historian described the device as "the most valuable cargo ever brought to the New World."
    In 1940, the best that US Navy radar sets could manage was 1kW, with very poor range due to a combination of low power and too low a frequency. In a meeting with US Navy officers, one of the British engineers pulled a cavity magnetron out of his bag, put it on the table, and said "That will give you 10kW output, at a much higher frequency, reducing ground effects from sea surface echoes, and with far better definition - and we expect it to be producing 25kW by Christmas." (which it did!)
    As for microwaves; what powers them? The cavity magnetron!

      All respect to British inventors and industry/science. Most people know what you say is true and good. This doc/vid is just TV entertainment with minimal elaboration. Because that is boring. Don't take it hard.
      Will say that the celebration of 'invention' is way over-rated.
      I don't care that some Germans or British built the first ICE cars. They were just toys for the wealthy. Who cares? Henry Ford (an American genius) delivered the technology to the masses. The Model T was the greatest car ever 'invented'. In my mind, he 'invented' the automobile! As we know it, today.
      A truly original idea is usually created by a nut, or a maverick. I consider it natural and good that it requires a second person who understands the concept (and it helps to have money) and brings it to market. Call me an American Capitalist Pig.

  • @allandavis8201
    @allandavis8201 Рік тому +1

    I am slightly confused, the German inventor made the first electro mechanical programmable computer,and Tommy Flowers invented the first electronic programmable computer that also used mechanical engineering to operate, what’s the difference, I am a mechanical engineer by trade and wiggly-amps and binary code means nothing to me, any one care to try and explain it to this old mechanic?
    You have to admire John Staff, he was either the bravest doctor ever born or the most idiotic person ever to risk his own life, but it was his sacrifice that has saved millions of lives indirectly and directly, if it wasn’t for him military pilots wouldn’t have the safety systems that they have today, ejection seats wouldn’t have been as quickly perfected as they are today.

      Early passenger jets were very expensive to operate. He is saying it not the engine that is the key, it is economic forces and design of the plane which delivered our modern world. It is more about time, money, and fuel consumption than the turbine jet engine.

    I don't have a cat but I'll tell you this, kitty litter works great when you're stuck in snow. We just had a blizzard here and I was watching four-wheel drives get stuck because there was ice underneath the snow.
    I got stuck in a four-wheel drive once and I had real good tires I must have been there an hour and a half until somebody brought me some kitty litter. I walked right out.

      You realize almost every truck driver carries from 15 to 100 pounds of kitty litter all winter. In mud, it can work as well. I drove for 42 years, carried a bag of cheap kitty litter and a gallon of cheap bleach. Sometimes bleach can give good traction as well.
