Nanokiwi Best of the Web
Firefox!
My favourite extensions for Firefox:
Adblock: the Firefox essential - only see the ads you want.
Greatly increases the speed of browsing over dial-up
Clusty Toolbar: Very handy addition to searching that hides away neatly in the corner of the Navigation Toolbar. Instant encylopaedia and dictionary clips. Try it to see how well it works.
Forecastfox: Weather for anywhere snuggled into your statusbar.
Gmail notifier: Lets you know when you have new mail in your Gmail account - I love Gmail
Magpie: Tool for gathering images. A must for anyone who collects images from the web. So handy you have to install it to believe it!
Quicknote: Notes, quick.
And its all free!

Has it flown away,
The cuckoo that called
Waking me at midnight?
Yet its song seems
Still by my pillow.
Oh this world of ours-
There is no way out!
With my heart in torment
I sought the mountain depths,
but even there the stag cries.

Nanotubes Make Antennas for Light
Technology Review: Nanotubes Make Antennas for Light
November 15, 2004
An antenna transmits and receives electromagnetic waves at wavelengths that are close to the length of the antenna, and it does so by converting electrical current to electromagnetic waves and vice versa. The electromagnetic spectrum spans radio waves, microwaves, heat waves, visible lightwaves, ultraviolet waves, x-rays, and gamma rays.
Carbon nanotubes, which are rolled-up sheets of carbon atoms that can be smaller than a nanometer in diameter, can act as antennas, but instead of transmitting and receiving radio waves, which are at the longest end of the electromagnetic spectrum, antennas of their size pick up the nanoscale wavelengths of visible light. A nanometer is one millionth of a millimeter. In contrast, radio wave wavelengths are measured in meters.
Researchers at Boston College, the U.S. Army Natick Soldier Center, Mega Wave Corporation and Florida International University have demonstrated the light antenna effect using arrays of multiwalled carbon nanotubes.
The method could be used to convert optical signals to electrical signals in communications equipment, to carry out optical computing, to detect different wavelengths of light including the infrared wavelengths used in telecommunications equipment, and to convert sunlight to electricity in solar energy applications, according to the researchers.
To make the light antennas, the researchers grew arrays of multiwalled carbon nanotubes that were 50 nanometers in diameter and varied in length from 200 to 1,000 nanometers. Visible lightwaves range from 400 to 700 nanometers long from crest to crest, which is about ten times smaller than a red blood cell.
The researchers measured the behavior of the carbon nanotube arrays by recording the lightwaves that the minuscule antennas reradiated.
Practical nanotube antennas could be developed in two to five years, according to the researchers. The work appeared in the September 27, 2004 issue of Applied Physics Letters."

democracy perfected!
"As democracy is perfected, the office of President represents, more and more closely, the inner soul of the people. On some great and glorious day, the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron."
--- H.L. Mencken (1880 - 1956)
