I think his most important invention to society is the hearing aid. He miniaturized the technology and made it possible for the deaf to hear. My mother (and many others) benefited from attending Bell Elementary in Chicago, one of the first schools working with deaf.

Alexander Graham Bell came up with the basic theory of fiber optics?? Mind blown. 😳

My sister and I grew up very close to Graham Bell's home in Brantford, Ontario, Canada. She was a tour guide at the museum there. We were raised knowing about his brilliance. My sister also spent time at his later home in Baddeck, Nova Scotia. One of our great geniuses.

The Alexander Graham Bell in Baddeck Nova Scotia on the beautiful Bras d'Or Lakes is well worth the visit if one happens to be in the area.

Alexander Graham Bell invented Squarespace? He truly was a century ahead of his time.

This may have been the inspiration for R. A. Lafferty's SF short story, "Selenium Ghosts of the Eighteen Seventies."

Bell was absolutely brilliant. Invented so much more than just the telephone

As someone who installs fiber optic cabling, I’m very thankful to the geniuses mentioned in this video. It still baffles me how glass can bend the way it does in fiber

Bell was a great inventor, but he had an eaven greater callings. Bell wrote what is was, and may till be, the greatest patent ever. His wording of the patent for the telephone allowerd is to stand up to countless court challenges by other inventors. With each case, the paptent was found to be iron clad until it eventually ran out.

It's amazing that "modern" technology was actually thought up over 100 years ago... 😲
Btw: fiber cables have come a long way. In the 1990s they had an attenuation of around 10 dB per kilometer. Nowadays fiberoptic cables used in national telecommunication networks have around 0.1 dB per kilometer... ✌️

3:34 No, Mahloon Loomis demonstrated electromagnetic (although he thought it was purely electric) wireless communication in 1865, and voice (using the improved Bell telephone of that year) in 1877.

While Alexander Grahame Bell invented the first telephone, he had no idea as to whether it would work until he invented the SECOND telephone!

[ruthbaker]

Wow. That is so cool. So far ahead of time.
BTW, he invented the metal detector to try to help find the bullet that was lodged inside of President Garfield after he was shot.

San Diego's science museum had (1980's) a whisper phone that was two parabolas positioned on opposite sides of a large room. You'd get your friend to go to the other one and each of you would walk up a flight of stairs where there was a circle you'd whisper into and place your ear towards it to listen to the response. A whisper was sufficient to hear but being children we discovered that yelling into it was more fun, because our shouts could fill the room and teachers would get angry trying to get us down

Wow! Way to go Alexander Graham Bell!

[Alan-pvbi]

I grew up 30 miles from Bells' home in Baddeck Nova Scotia, great museum there!
Everyone should watch both first flights, Write Brothers and the Silver Dart, compare dates and flight paterns 😂

There was a book of electronics project plans going around in the 80s and 90s that had the plans for a laser driven photophone in it. I had a copy that I bought from Lindsey Publications out of Chicago, which was stolen from me not long after I got the thing.

Actually, to make optical fiber work efficiently you have to add specific elements ("doping" it); the result is a less pure glass, but it works better.

This is my favorite channel of yours because you don't play music while you talk. 😘
