Yes, light speed can be slowed to 1 m/s using the Bose–Einstein condensate
But (theorically) nothing can go faster than light because the same light can't travel faster than its speed, infact:
The speed of light emitted by an object in moviment can be only less or equal than the C value, and not major

Ok, so if they change the metre around to match the speed of light, what made them choose 299,792,458 in the first place? Why not 300,000,000 and just change the metre to match that?

Because it doesn't sound as geeky as 299,792,458

winkwakr: That is actually quite a good question. I would guess that it is either:

a) Because there are other measurements which are rounded nicely as such with the meter as it is.
b) Because when the meter was first defined they were unaware of the speed of light.

A metre is defined as the distance light travels in 1/299792458 seconds in a vacuum. This reduced uncertainty in the vacuum wavelength, the medium's refractive index and the laser count of the interferometer.

Because the metre is an International Standard and changing it means change (about) all the measures for all the things.
Also it means change all metre derivative measures (areas, volume, density,...)

This job is too expensive!

But the first definition of the metre is the lenght of a iridium-platinum bar stored in paris

- what is horse power?
- horse power is a power, produced by horse with height 1m and weight 1kg!
- where did you see such horse?
- it's not easy to see it! it is stored in France, in Palace of measures!

; Mr. Green says:
   I'm into the palace of measures in Paris...
   Where's that horse???
; Mr. Blue says:
   It's hard to see!
   It's a kind of INVISIBLE horse and you can't find it.
; Mr. Green says:
   So, where can i go? What can i do?
; Mr. Blue says:
   Go to Britain and ask for it

   ..... TRAVELLING ....

; Mr. Green says:
   Here i am, in Britain!!
   Hey guy, what's about HORSE POWER?
; Someone says:
   You're looking for the Horse Power?
; Mr. Green says:
   Yes, where's my horse?
; Someone says:
   Here is a power horse that is 
   "the power used to move 75 KG of matter over 1 Metre in 1 Second"
; Mr. Green says:
   That's not my horse!
; Someone says:
   mmmh... Your horse.... Where do you come from?
; Mr. Green says:
   I'm from a far island
; Someone says:
   Maybe you lost your horse there...    

To be continued Very Happy

Here is good article about Intel's latest chip: Lynnfield. It give some small insight into the types of trade-offs and decisions that have to be made when making chips. The first part is the most informative, after that it gets boring into graphs and numbers that are meaningless unless you have the exact same setup that the testers had.

BBC Horizon: 1977-1978 Now The Chips Are Down

The first twenty minutes gives some more insight into the production and design. Then follows the public impact and some predictions. See if you can spot how many of the predictions were correct and how many were wrong.

The Extreme Physics Pushing Moore’s Law to the Next Level

A little bit of self promotion for ASML but still gives some insight into some of the challenges involved in making those tiny transistors.
