Bro I just watched the ones from the 80s and 70s and this is PERFECT timing. It's so crazy seeing how different things were, and what excited people. Thanks for posting with impeccable timing!

Mum got a microwave oven in 1979 and was replaced 3 years ago. Was still working too. 40 years of usage.

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.

"Let the cat out" as a common phrase died with kitty litter, too.

Many great things are invented by those who don't know they can't possibly work.

Conrad Zusa may have created the first fully programable computer,,,, but he did not invent the computer

Having spent time writing tech manuals under contract to Raytheon during the 1990's JPATS (turboprop) Trainer Program, I have nothing but respect for the technical achievements advanced by that company, and it's employees!

Percy Spencer, never heard that name before now, quite the impressive fella!❕

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.

People should read the autobiography of Edwin Land. He was the picture of outside the box thinking. He coined the phrase -- INPERT .(some one who comes from outside of the generally recognized field. (and doesn't know "it can't be done that way")😊

The invention of the jet engine wasn’t responsible for inexpensive flights.

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.

Thanks for posting this --- very informative & interesting!

Can't help but Wonder if Percy would have had the same opportunity today without the formal education and the politics involved with it

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.

25:02 The University of MassaTUsetts? And all these years I thought it was Massachusetts.

I thought the mechanical calculator was developed to allow ARTILLARY COMPUERS (Men) to do accurate Targeting, during the Great War (or soon there after.)

Yeah, but the modern (and safer) three-point safety belt was invented and "pushed" by the Swedish company Volvo, don't forget that!

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!

A Staff infection saved automotive lives.

The mockups are unrealistic to varying degrees, but the magnetron mockup triggered me to write this comment.

Outstanding and impressive well of superb technical information to each and everyone that one way or another made it possible to bring it to you my most expressive thanks for the information, my gratitude towards you guys, blessings to you and your family, from the endless summer paradise Puerto Rico Jesus Torres.

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.

ADVERTISMENT: i CANNOT FIND ANY GOVERNMENT STIMULUS MONEY FOR OLD PEOPLE (LIKE ME).

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.

26:55 I saw the truck and thought there was a Ford F1 but that is a Mercury made truck. I did not know Mercury made knockoffs of their Ford cousins.

Whittle has an epiphany while considering a Curtis P-40? Puleez. I am consistently disappointed by the silly mistakes that the people associated with too many technology/technical videos don't realize is a silly mistake.

It's the first I've seen it and i found it to be very inspirational.

Earl Tupper had nothing to do with marketing other than paying a woman who was brilliant and excels at it, but he treated her poorly.

Jet engine!!!!! Britts!!!!! Hmmmm food for thought

the A-Bomb and the H-Bomb two inventions that actuary shook the world

The most important invention of the 40s was, without a doubt, the transistor. How did you miss this?

Crazy he had an American accent

18:00 in the video that time travelling Putin in the picture? lol

The subtitles are terribly out of pace with the clip.

This picture is ridiculous. The atomic bomb, it explodes the boundaries of warfare. That's the extent of the entry into the atomic age? Seriously? That's about the most disrespectful and incomplete description of one of the most impactful inventions in human history.

What? You couldn't find actors with English accents to play the parts?

This is a old video saw it long time ago. So whats up with that?

JWIGM!
