@@piyushagarwal7376 Actually it wasn't Narinder who did it originally. Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the early 1840s. John Tyndall included a demonstration of it in his public lectures in London, 12 years later.[12] Tyndall also wrote about the property of total internal reflection in an introductory book about the nature of light in 1870. In the late 19th and early 20th centuries, light was guided through bent glass rods to illuminate body cavities.[15] Practical applications such as close internal illumination during dentistry appeared early in the twentieth century. Image transmission through tubes was demonstrated independently by the radio experimenter Clarence Hansell and the television pioneer John Logie Baird in the 1920s. In the 1930s, Heinrich Lamm showed that one could transmit images through a bundle of unclad optical fibers and used it for internal medical examinations, but his work was largely forgotten. In 1953, Dutch scientist Bram van Heel [nl] first demonstrated image transmission through bundles of optical fibers with a transparent cladding.[16] That same year, Harold Hopkins and Narinder Singh Kapany at Imperial College in London succeeded in making image-transmitting bundles with over 10,000 fibers, and subsequently achieved image transmission through a 75 cm long bundle which combined several thousand fibers. So really, who was first depends on which stage of development the technology was at. If you're talking about bundled optical fibres then it was Bram van Heel who first did a demonstration of Fibre Optics, and if you still want to say that it was Narinder Singh Kapany who did it first then you cannot mention him without Harold Hopkins. In actuality, it was the culmination of these men which inspired Charles Kao with the help of George Hockham to pioneer modern Fibre Optics by reducing attenuation in optical fibers below 20 decibels per kilometer (dB/km), making fibers a practical communication medium. A vast leap in the technology from simple image transmissions.
@@KnotsOfWonders Wow, just WOWWWWWW, That was truly the best comeback I've ever heard/read. ❤ Thank you so much for that, absolutely amazing and fascinating.!!! 🤯 Have a great 🌙 night or day 🍁🌳🍁 (depending on where you are in the world 🌎 Sending everyone much love from the 🇺🇸
Absolutely incredible to understand these concepts in this time. To invent such machinery, Charles K. Kao is a science pioneer, inventor and his legacy will forever improve our lives
I challenge the social media community to support Dr. Kao's contribution to society by spreading awareness of Alzheimer's disease and supporting his foundation.
This is amazing and fascinating 😳🤯👀 Thank you so 🙏 much for posting this. And as for everyone who argues about who invented it first, who cares!! It's not a competition!! Just about every country in the world 🌎 makes a contribution to science, mathematics, music 🎶 , and culture. Where you come from doesn't matter. People are people. Our insides all look the same, and we all bleed red.
Inventors change the world.
*Thanks to Charles Kao* we can all enjoy the Internet at very fast speed, where such fiber cables exist.
idiot Narinder Singh Kapany did it originally in 1952 google that atleast
India did not work practical in science,work in pretty mouth
proud of hong kong
香港人的驕傲
Without you we are still using 56K network. Thanks for the break-through invention.

Sir Charles K. Kao
Thank you very much for posting this video.
R.I.P. Professor Kao. Hong Kong is very proud of you. We all will very missed you.
Narinder Singh Kapany did it originally in 1952 google that atleast
Rest In Peace Charles Kao 🙏🙏🙏🙏
Wow, what a precious video! Thank you so much for posting this!
RIP Charles Kao
Respect
Rest in Pease Professor Kao.
Rip Charles kao
We will forever miss u
Great video!!!! Thanks
rest in peace😭

Hello, may know where can I watch the whole documentary?
yea rest in peace
heroe.
Im watching this for a school project ok
Narendra singh Kapani... Father of Fibre optics...
Kapani along with Hopkins made the fibre ... kao invented fibre communications which is more important
Tesla Laymans terms this man fiber optics
Nice dude, i hope someday i can get a noble prize for something ....
twilight0111 It''s an award for profoundly changing the world we live in. Not some lucky lottery prize!
Narinder singh kapany father of fiber optics
are you saying that out of hate? do your research first, you dumb fuck.
Kapani along with Hopkins made the fibre ... kao invented fibre communications which is more important

Narendra singh kapani invented optical fibre. But dr kao copy him and got credit this is very bad...

He was a cheater
