Flat Earth on Wikipedia

In a rather bizarre Wikipedia discussion about the flatness of Earth, I found an interesting statement:

– At the scale of less than 10^-9 meters or so, the earth is a space has an undefinable shape.
– From about 10^-9 meters through to about 10^4 meters, the earth is flat.
– From about 10^4 meters to about 10^9 meters the earth is a sphere.
– At the scale of anything greater than about 10^9 meters, the earth is a point.

I guess the morale is that everything is relative.


Georg Hajdu has just released a new version of his Quintet.net performance system.

“Quintet.net is an interactive network performance environment invented and developed by composer and computer musician Georg Hajdu. It enables up to five performers to play music over the Internet under the control of a “conductor.” The environment, which was programmed with the graphical programming language Max/MSP consists of four components: the Server, the Client, the Conductor and the Listener; the latter component enables the Internet/network audience to follow the performance […]. In addition, there is a Viewer add-on for the Client and Listener components.”

Open Sound Control forum

The CNMAT people have made a forum at the Open Sound Control site. OSC is a way of communicating musical information between devices, much in the same way as MIDI, but without all the problems of MIDI (low resolution etc). Although OSC seems to have gained ground in the research community, I think we all have to support it more if it is ever going to be accepted by the commercial industry.

Mirror Neurons

The concept of mirror neurons was discovered at the University of Parma, Italy some years back, and shows how we have the same neural activitiy whether we do a movement ourselves or just watch someone else doing it. NOVA has made an excellent documentary about mirror neurons.
