Light and sound and some thinkwork

In a city there's light everywhere. Sometimes it's dim, in a dark street corner, yellow light from the light pole. A broken fluorescent light that flickers before it goes totally dark. The way too bright light in the city trains, that shows how tired all the people are in the evening when coming from work. The light in the stores, that leaves no shadow behind.

For this post I want to talk about sound and light. Because the artists that I'm going to talk about use light or sound in an exceptional way. But before that we have to go down to the very basics of sound and what it is.
This is taken from Wikipedia: ( ^ The American Heritage Dictionary of the English Language, Fourth Edition, Houghton Mifflin Company, 2000, archived from the original on June 25, 2008, retrieved May 20, 2010 )  Shortly, but clear;

"Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations."

And what is light? Some scientists have found now also that some neutrinos have possibly moved even faster than the speed of light! That is something and if it's true it will turn everything in to a new order. Here's a link to the news: http://news.nationalgeographic.com/news/2011/09/110923-neutrinos-speed-of-light-particles-cern-physics-einstein-science/ Also from Wikipedia ( http://en.wikipedia.org/wiki/Light ):

"Light or visible light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has wavelength in a range from about 380 nanometres to about 740 nm, with a frequency range of about 405 THz to 790 THz. Inphysics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarisation, while its speed in a vacuum, 299,792,458 meters per second (about 300,000 kilometers per second), is one of the fundamental constants of nature.

Light, which is emitted and absorbed in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics."

So light can move in a vacuum, so not needing any substance to move in.

Sound needs something to move in.

So now, when we know bit more I want to present you Finnbogi Petursson, he's Icelandic sound/installation artist. He has created many pieces with interesting search what kind of patterns different sound wavelengths give and how the sound can feel in space. Listen these with headphones on.

"Deep 2010"

"Pendulum 1993"

"Circular Cubes 2002"

You can check more of his work here: http://www.finnbogi.com

Finnbogi Petursson will be performing in Rewire festival in Den Haag 4-5.11

Optical Machines creates soundscapes with amazing visuals. They are a Dutch duo: Rikkert Brok and Maarten Halmans. They create the sound and the visuals on the spot so you can actually see how it all works. They have amazing video online that you have to listen with headphones on and from a big screen!

And still something very awesome. I have never seen it live but this video tells a lot. Watch also headphones on and from a big screen. It is a 3D projection, put that in youtube search or "3D projection on building" and you'll find out more.

And some think work for everybody. Both links from Wikipedia:

Fibonacci number. Which explains everything in the nature:

"They also appear in biological settings, such as branching in trees, arrangement of leaves on a stem, the fruit spouts of a pineapple, the flowering of artichoke, an uncurling fern and the arrangement of a pine cone."

Golden ratio:

Flower of life, found also everywhere around the world:

One thing that explains everything? Isn't it a beautiful idea?
