Scientists make light travel backwards, very fast

Physics stuff to make your head hurt...


I like this part:

Boyd, along with Rochester graduate students George M. Gehring and Aaron Schweinsberg, and undergraduates Christopher Barsi of Manhattan College and Natalie Kostinski of the University of Michigan, sent a burst of laser light through an optical fiber that had been laced with the element erbium. As the pulse exited the laser, it was split into two. One pulse went into the erbium fiber and the second traveled along undisturbed as a reference. The peak of the pulse emerged from the other end of the fiber before the peak entered the front of the fiber, and well ahead of the peak of the reference pulse.

FTL Star drives; Time machines anyone?

Interesting, but I don't see how it relates...

to my original post.

Two examples of man taking charge of natural forces, I suppose.

it made me think of the apod link. Incredible discoveries, their magnitude and final use way beyond my kb.

LSD was a good thing. Happy

For awhile, we had a little program that let us know when a we had a call, but that still wasn't acceptable to me.

Okay. Just make sure you don't call your service provider...
by EdH / May 14, 2006 1:08 PM PDT

and tell them you want to discuss payment for your LSD.

I've talked to them referring to the service

as my LSD service.

The problem with this faster than light stuff is that it

cannot be made to carry data. The data gets scrambled along the way, so you can't use it to communicate. Theres some very high powered math that goes along with that explanation which I comprehend not at all.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
