agricoltura | info | prezzo | dati | produzione
http://www.ted.com In 1998, aircraft designer Paul MacCready looks at a planet on which humans have utterly dominated nature, and talks about what we all can do to preserve nature's balance. His contribution: solar planes, superefficient gliders and the electric car.

por que manter o nome do tradutor e do revisor o tempo todo no video. Que coisa feia e metida. ........... estragou o video e dificultou a vida de quem teria interesse em com ele evoluir. Uma pequena amostra da pequenez humana

Does anyone know where I can get a good resolution image of the graph he shows at 2:08? It is one of the most sobering figures I have ever seen.

FUCK THIS AUDIO!
-
Audio's out of phase
-
weird stereo sound effect is kind of disorientating!
-
@twochaudio also, fuck you. He's not a doomsayer, he saying "these are all the horrible things we're leading to if no one does anything about it, and here's what I'm doing about." What are you doing about it? The people who've lived through most of the 20th century have a hell of a lot more perspective of the direction of human intent and ability than a few fucking youtube pundits.
-
oh 20th century, how funny you were, back when even people at tech conferences can't get the damn projector to work.

And what it means physically, is that when the left speaker cone is moving forwards, the right speaker cone is moving backwards, and vice versa. These movements correspond to increased pressure - when the cone moves forward, and decreased pressure - when the cone moves backwards. It sounds (and feels) strange because one ear is experiencing an increase of pressure while the other is experiencing a decrease of pressure.
Swap the cables on one speaker to fix the sound.

The left and right audio channels are out of phase by 180 degrees.
If you've ever wondered what people mean when they say that audio is 'out of phase', you are now hearing it. It sounds very strange and it puts what we call a 'hole in the middle', between the two speakers. If you are not hearing a problem with the audio, then your speakers may well be wired out of phase (i.e. black to red on one speaker). There is also a harmonic feedback issue, but most people probalbly don't even notice that.

I can also hear the audio fine. I have powered speakers, and they're not up very loud... but it sounds like the left and right channels are out of phase...
-
The only thing I can hear at max, is my computer fan :(

Hi TogieTung.
I just googled his name.
From Wikipedia:
"Paul B. MacCready, Jr. (September 25, 1925 - August 28, 2007)"
Great guy, very sad.
-
ya man.. cant hear a shit.. i maed out the volume and it still sounds a little soft..
-
I can hear it fine... Do u have powered speakers or are you on a laptop?
-
... or if you can't speak up, can you arrange for that friggin' TED fanfare at the front end to be QUIETENED DOWN for crysake?!
-
Can you repost this video with audio?
-
yea but lets not waste billions of dollars cutting co2 emisstions when the whole concept is on less than solid ground.
-
Even if it is, we still need to develop better tech. Sooner or later we are gona leave this rock. Might as well as develop it asap, so we can be less dependent even on earth materials but, that won't happen still for awhile.
-
the audio is very faint.
-
no audio... to bad :(
