Well, it's what I have been telling you about all along. And I do know how to turn a flashlight on and off.

No Corkscrew Required

[FreeKeys]

Cool!

Science ping.

[rightwingreligiousfanatic]

I hear this guy invented the original prototype!

[RightWhale]

if you could freeze an ordinary beam of laser light, you would see a neat series of waves, crest following trough following crest.

Kidding, right?

From spinning dust motes to Photon drive.
We see history happening before our eyes.


This could be the humble beginning.

Since the photons are taking a helical path, does it take more time then a straight path?

"If you say to people, there's a device we haven't built yet, based on untried technology, using physics you've never heard of, but I assure you it's going to work...well, it's much better to demonstrate it to them."

Heck, 3 years ago, if you put a dot com on the end of it and had a good sock puppet mascot, they could have gotten a couple of billion in venture capital.

All the cool stuff is going to start happening when I'm dead.

I did see the moon landing though. And my grandmother was alive for the Wright's flight and the moon landing.

"Unlike polarisation, which is restricted to just two states (clockwise and anticlockwise), orbital angular momentum can take on an unlimited number of possible states."

I was thinking circular polarization as in microwave until I came upon this.

My brain just exploded trying to understand the article.

ping...

Thought y'all might find this interesting if you hadn't seen it before.

[neuron2]

No graphics and no link to the original article. Shame! Back to Posting 101 for you.

[Talking_Mouse]

bump to read several times and try and understand

[philetus]

But, will it corkscrew the other direction in Australia?

[GOPJ]

Beam me up:

If you could stand on a wave crest and walk around the beam, after one complete circuit you would find yourself standing one wavelength away from where you started.

Circular polarization.

Fire a beam of its laser light at the dust sitting on your tabletop and the dust motes will begin to dance around in circles. Fair enough, that's not quite a killer application.

Spoken by someone who's never seen the dust on my desk.
