Those were some amazing stories. I've seen my fair share of old mechanical exchanges, in the basement of a 100+ year old telco. I worked there years ago. I had heard of wheatstone, but had no idea he created a one wire solution. I listened to every word, fascinated. Just like all your videos. Thanks!
When I think I know the story behind an invention, now common in our world, Mr Gelbart tells me the full story with details I didn't know. I have only recently discovered his channel and am watching as many of his videos as time allows. I've already learned much from listening to him speak. What a great man, I wish I could spend a week chatting to him and learning.
Dan, as always it was a real pleasure watching another of your wonderful videos... your knowledge of all things mechanical and otherwise that you share is most appreciated... I had hope that you would do more after your series of 18 around you shop...Thank You Sir!!!
Thank you very much Mr. Gelbart for sharing these interesting stories and historical exhibits. I really appreciate your effort and enthusiasm in showing them to us. On a sidenote that might amuse you: "Invigorating" trinkets had a short comeback not too long ago in the form of hologram wristbands made from silicone and a mysterious "negative ion powder". That powder being Thorium, Thorium silicates and oxides respectively. It's getting even closer to the case of radium doped jars (albeit way less funny) when you hear about ceramic milk bottles for babies being made with it. Nevertheless please keep it up. Fantastic insights!
Thanks for showing us your amazing collection. I would love to see a video on the history of machine tools and foundations of mechanical accuracy? You seem to have a deep knowledge in these areas as well.
That was a completely unexpected, but interesting nonetheless explanation of many things that I knew about on the surface, but without the colour that your explanations added.
The proper name for the vibrator was actually the "interrupter". As a kid in the late 60s, people would give me piles of those old tube car radios and I would repair them by smacking the vibrator abruptly on the table. This would unstick the contacts after years of sitting and oxidizing. I repaired one of these radios as recently as 1998 for a dear friend. It came from his first car, actually a 1950 Ford pick up truck. He cried when he heard his old car radio again after so many years. Rest in peace, Mark.
Pupins name was Mihajlo and AT&T already had Campbells patent so that story is bunk and I have a strong suspicion that the Carl Bosch letter is also a myth.
The story about Pupin is in the book "Sage in Solitude" by Nahin, a highly regarded biography of Heaviside. It also shows up in other biographies. If I have the time I'll also find you the Bosch letter.
@@dgelbart I would love to read the Bosch letter as I was unable to find it after quite a bit of searching. As for Pupin, the story makes no sense. As previously stated, AT&T already had a competing patent.
@@galileo_rs The Bosch prediction can be found in the book "Enriching the Earth" by a very credible historian, Vaclav Smil, on page 225. In the book it refers to it as a message to his son. Smil cites the source as a book by Holderman (see details in ref 6 p.324 of Smil's book).
@@dgelbart I see by my browser history that I already downloaded this book and unless I'm going senile we already discussed it previously: This states that he foretold the events orally to his son, initial claim was that he wrote a letter. The reference on page 324 is 3 books in German and I don't understand German so I can't check those out.
2020 has been an absolute rollercoaster and seeing the man, the myth, the legend Dan Gelbart bless our YT feed has absolved me of most of my ill will towards this year
I wish you had more time to make videos like this. Just so much to learn. I always thought that there was more to the story then what we are being told. Thank you!!
Sir, thank you for the nice presentation. By your narrative I could feel you do have not only a heart of an engineer, but the also the mind and the soul. Well done!
Your work and knowledge is appreciated and cherished. Thank you for your life's work, and the consideration to share with the world your historical and practical expertise.
I love this man. He has a rare ability to explain only the bits one needs to tell his story. I wish he lived next door. My dad was an engineer and any answer to a science question I asked him started with pulling out his ballpoint pen.
Excellent. 8 very interesting stories. That laser looks like a prized possession, and rightly so. I am struck by how from, say, 1920 onwards, technological innovation has been dominated by corporations employing engineers, not engineers forming corporations, and how bad they have been at their supposed job. You'd think the criticism would be that they fail to understand the technology but are good at monetising other peoples inventions - but your stories involve them being absolutely lousy at understanding what might make money. I mean, I could forgive them only giving Ted Maiman $50k and a year, if they thought the ruby was a dead-end - but because nobody wants a laser?? Or nobody wants a car radio? Market forces may be good for many things, but identifying products of the future isn't one of them. I suppose because the last thing you need to become a top executive is a good grasp of what people might want.
I think if you look at the founders of most of these enormous corporations you will find your engineers more than financiers at their start and that often when the high echelons are purged of the progenitors they tend to lose impetus and melt away. In Dan's story about Carl Bosch also recall that in 1925 Bosch helped found IG Farben, and was the first head of the company and from 1935, he was chairman of its board of directors. It was the largest company in Europe and the largest chemical and pharmaceutical company in the world until broken up after WWII. [Wikipedia]
Wow. Such a great story teller. I could listen to this man read me the ingredients on the back of a cereal box and be just as captivated. Thank you Mr. Gelbert for sharing some of your collection and the interesting stories behind them. I'd love to see and hear about more of your collection of inventions and their inventors!!
@Dan Gelbart Many thanks for taking the time and effort of making and sharing Your excellent videos. I find them both educational and entertaining, and it's content of this kind that makes RUclips worth while in my humble opinion. Best regards.
Yes, there certainly have been some 'unusual and suspect' Nobel Prize decisions, both in prizes given and not given. I once read that when it comes to the Nobel Prize in physics, you don't get it so much for being brilliant but rather, for being right. Ted Maiman got it right when many others, brilliant as they may have been, got it wrong. Considering how important the laser is to science and to society in general, Maiman certainly deserved the Nobel for his accomplishment.
I have been to this wonderful place twice, but I'm too busy running a company right now. I try to see all the science and technology museums in the world as they will all close down (many already did) because of low attendance.
ODDLY - it turns out that radioactive water (well low level exposure to radiation) IS healthy for you! funny that. but they did not know this at the time!
Thanks for the video. I'm in the process of restoring an Edison Standard Phonograph. I've completed the main unit but it is lacking the horn. Your video gave me a good idea of the size, style, and structure of the original. A little disappointed that you didn't get round to the Curta calculator you had on the desk. I have one that was issued to one of the designers of the UK's first atomic power stations. Curta's story is fascinating.
Fantastic, I really look forward to new videos from you Dan. I re-watched the spot welding episode over breakfast and coffee yesterday. I appreciate you taking your time to make these and share with us! I would love to spend a day with you learning and chatting!
Thank You Dan, for the wonderful backgrounds and insights to these inventors and inventions. I won't forget these now. I've always felt it's important for us to realize the origins of things and get a feel for the creative geniuses who came up with them. Also, really appreciate seeing your collection and perspective. In reference to the latter part on fraud, I'm Curious about your insights into Royal Rife. Thank you again for what you bring to us!
wonderful video full of history i will watch again with my son. it is really interesting to know how strangely life works for everyone including great minds. great to see you again dan. take care ps loved the humor too :)
Great video! Thank you for sharing your vast knowledge. Please make more! If your lathe ever needs a new home give me a holler. LOL Still dreaming about that thing 5 years later....
I remember when the Telephone Central Offices were full of "automatic" electro-mechanical switches, (they were called 'Step Switches'). The clatter of hundreds of these switches all operating at the same time was something to behold. It sounded like you were in a tin shed during a hailstorm, but it went on all day. In the modern Electronic Switch Telephone Central Office the whir of the cooling fans is about all you hear. I was in a Telephone Switching Office on Edwards AFB California the day President Reagan was shot in 1981, and the electron-mechanical switches went crazy. It sounded almost like an explosion, and a Sergeant with me said, "Something important has just happened". We exited the building and turned on a portable radio, (the thick reinforced walls of the building made radio reception very difficult), and found the President had been shot and wounded.
Yes indeed. Charles Wheatstone is known both of his contributions to musical instruments and to electricity: Wheatstone bridge, Wheatstone 5 needle telegraph, single wire telegraph and more.
@@dgelbart Awesome, I love that brass and wood artifacts, and the history of it, as a musician, I just love all of this. And I forgot, thank you for the Prototype making series!!! Big fan of your videos 😊 I get a lot of knowledge every time.
@@dgelbart And the Stereoscope I believe ~ I also collect electrocution and plasma based quackery - such fun. The "Haber" presentation was quite haunting. Some terrific artifacts there.
Where to start. A great collection expertly curated. You are an excellent communicator with intellect and an obvious sense of humour. Your anecdotes about Maiman were to me especially interesting.
