HOW IT WORKS: Lasers (720p)

Love how dramatic and cinimatic old-school documentaries are .

Love the music too.

I recently saw a documentary where a teenager went to the year 2015! But I don't see hover boards or flying cars anywhere! What gives? Maybe I got the year wrong.

HOW THEY WORK?????????????????????????

Whew! It takes determination to view this video. Horrible music and a sluggish pace and a monotone are brutal. Thanks, however, for the video. Lots of good info.

these was good

nice

any details on this documentary? like date publisher and whos narrating?

Why were they called MASERs?

Interesting that nearly all the predictions they made for the laser back then came true. Lasers for welding… Check! Lasers for surgery… Check! Lasers for communications… Check! Lasers for lunar range finding… Check! Yet even they knew the full potential of this incredible device would not be realized until long into the future.

why are the videos so crap back then LSD must have been ripe

"Yet this narrow pathway of light leads surely to tomorrow" light is awesome…!

and yet the communication between man and woman is as bad as ever lol

Its been decades, where's my fucking ray gun!?

I like these old school documentaries with their mysterious music.
