Daniel Kish: How I use sonar to navigate the world

31
5



Daniel Kish has been blind since he was 13 months old, but has learned to “see” using a form of echolocation. He clicks his tongue and sends out flashes of sound that bounce off surfaces in the environment and return to him, helping him to construct an understanding of the space around him. In a rousing talk, Kish demonstrates how this works and asks us to let go of our fear of the “dark unknown.”

  1. Omg. Parents could learn a lot from this guy. Parents need to put their kids freedom first instead of instilling fear.

  2. This is why I have a hard time writing 'see' to explain something. "We 'see' that" doesn't mean a person who can't see is ignorant. It means those around him failed to understand the world without a sense they put so much faith in

  3. I saw Daniel in action on the BBC America program "Wonderstruck" and had to investigate. It was amazing to see him riding a bike down a trail. I'm glad to know he has an organization to help others learn this amazing skill of echolocation. He's an eloquent speaker and explains things very well.

  4. Not any words I can think up to describe this man. I know my common sense tells me he on purpose or not has developed his hearing to be much greater than most of us. Super impressed here.😉

  5. Lol I remember discovering this when i was s kid. I used to like to click my tongue when i was younger, and eventually realised my clicks sounded different when I was near an object. Years later, I realised I was echolocating. Im obviously not good at it like he is, but I can close my eyes and tell if im about to run into a wall, or how large a room is. You can sorta hear the emptiness of a large room, your click sounds softer.

  6. One of the most inspiring and interesting ted talk, i've been coming back here again and again for weeks… this is very interesting

  7. At least he doesn’t have to blind. He has no real eyes to give off the sensation to moisture his eyes.

  8. TED talks are great, but nobody should ever use them as a substitute for a basic, scientifically-based education lol these people are sharing their own, subjective experiences.

    And those experiences are quite unlikely to apply to many others, if anyone else at all.

    (I'm just sayin') 👍

    We've all found ourselves in a debate, or a straight-up argument lol in a forum or a comment section with someone who thinks that, because they saw a TED talk on a subject, they have an intellectual, "edge," over everyone else.

    Distinguishing between subjective truths and objective facts is fundamental to maintaining an informed society.

    Scientifically literate populations are the engines that will drive the world's economy, and when that process begins to slow down, you may as well be going backwards because that's what you look like to the rest of the world.

    There is something very satisfying and even fulfilling about some of these TED talks, they offer inspiration and there's obviously nothing wrong with that lol don't get me wrong!

    I'm just sayin' a TED talk doesn't make anyone a foremost authority on any subject, with one exception; the person who's doing the talk.
