Slow Light Laser

Slow light

Could this be the basis of quantum computers? Maybe…

Physicists in Australia have slowed a speeding laser pulse and captured it in a crystal, a feat that could be instrumental in creating quantum computers.
The scientists slowed the laser light pulse from 300,000 kilometers per second to just several hundred meters per second, allowing them to capture the pulse for about a second.

Adaptive Optics Produces Ultrasharp Images Of Sunspot

Adaptive Optics

Greg sent this to me:

The Dunn has two high-order adaptive optics benches, the only telescope in the world with two systems, which enhances instrument setup and operations.
This image was built from a series of 80 images, each 1/100th of a second long (10 ms), taken over a period of 3 seconds by a high-resolution Dalsa 4M30 CCD camera in its first observing run after being added to the Dunn. Speckle imaging reconstruction then compiles the 80 images and greatly reduces residual seeing aberrations.

I wonder if any digital camera makers will ever offer adaptive optics on their products. It may not be practical to do the layering of images if your subject is moving, but it might be useful to chart out the lens flaws and build a digital filter to correct them in camera.

Dr. Mabuse

Dr. Mabuse

A few nights ago I happened to see an old B&W German film by Fritz Lang called “Testament of Dr. Mabuse”. It was fantastic! I have long been a fan of German expressionism in films like ‘Metropolis’ and ‘The Cabinet of Dr. Caligari’, the use of light and shadow in these films is just breathtaking.
The story behind Marbuse is one of a sinister and pure evil man bent on social destruction and chaos. He’s not like an evil genius of today where he has some major character flaw or he ultimately wants money or power. Marbuse wants chaos and anarchy. Ordering his men to steal a quarter million Marks worth of gems and jewels in order to buy as many narcotics is one thing. But to also order that the drugs be given away for free to anyone that wants them and thus hooking more of the population is just pure evil.
If you want to own a copy of this great film, pick up the Criterion release. It’s going to be well worth it.
