It's a little old, but has never been posted here.

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!

[Lurking Libertarian]

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?

Science list Ping! This is an elite subset of the Evolution list.
See the list's description in my freeper homepage. Then FReepmail me to be added or dropped.

Flying pancakes. Bunny rabbits.

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


This could be the humble beginning.

[longshadow]

can you say "circular polarization"?

How is this any different?

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.

[tet68]

Kind of interesting, does it take the same time but go farther, or does it go the same distance but take longer.

Or is everything constant?

My head is spinning.

Must be the Dirac field.

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.

[stylin_geek]

I'm stuned.

[Darksheare]

Not my fault!
