Geoengineering

Geoengineering involves changing our environment to suit human needs better. This article looks at ways geoengineers have thought about reducing global warming by not reducing greenhouse gasses, but by proactively doing something about it. Some pretty far out ideas, such as floating white plastic islands in oceans, space mirrors and lacing the atmosphere with sulphur are brought up. Science is starting to look at these options more seriously and trying to get funds for them at a small scale.

Wireless FM transmitters

This is a device you attach to your mp3 player, either through a port or via the headphone output, which then allows you to select a frequency and transmits the music on FM on that frequency. This allows you to tune your radio to your mp3 player.
In the Netherlands they are finally legal (since about one month) so I decided to get one.
Walking through town I couldn’t find any, except iPod dedicated units (which use the port, so are only iPod compatible). There are 2 Apple versions: one which only works for a dedicated model (eg. only for the nano) and one which works with all iPods except the very first model (and presumably any model they release in the future). These both look slick and work with the ipod seamlessly. Unfortunately they are expensive and iPod only.

If I’d had time I would have gone for the Linex FM transmitter, which connects via the audio jack. It’s bigger than the iPod thing, but it’s around a third of the price.

Computers reading emotions

Our faces express our emotions – apparently there are around 20 key facial movements expressed around 24 facial feature points, which betray our emotions. By scanning these points intelligently, and detecting things such as facial form, computers can read the emotions of those using them.
Ideas posited in the article: websites advertising products directed at the emotional state, detecting boredom or sleepines in cars and helping people with Asperger’s syndrome (difficulty in recognising emotions and facial expressions).

Measuring gravitational waves

2 gravity wave detectors have been switched on, trying to prove and discover waves posited by Einstein as part of his theory of general relativity.

The Americans have a huge isolated lab called LIGO (Laser Interferometer Gravitational-Wave Observatory) run by a few people from the LSU and California Institute of Technology in the middle of Livingston Parish, LA.

Britain and Germany have their Geo 600 Detector in Hannover, run by scientists from Glasgow, Cardiff, Birmingham and Hannover Universities.

Apparently there’s also a similar experiment in Japan, but I couldn’t find the links to that.
