![]() If, however, I started travelling towards you, so that each day that I travel knocks a day off the postage time, then at some point you will receive five letters from me all on the same day. After an initial delay of five days you will receive my first letter, and after that the letters will arrive daily, as each takes the same time to travel to you. To see why it works this way, suppose I lived a long way from you, and wrote you a letter every day, the letters each taking five days to arrive by post. Clearly the real tick-rate of the clock does not change. If you turned round and started moving away from the planet, the clock would seem to be running slow. If you are moving towards a planet and you were able to study a clock on it through a powerful telescope as you approached, the clock would appear to be running fast. Interview on We-make-money-not-art.The Doppler effect relates to the rate at which events appear to be happening when viewed from some distance, rather than the rate at which they are happening, and the difference between the two rates is caused by the time it takes for the information about what is happening to travel from the source to the observer.

In this way their genes will become dominant in the water flea populations and a “contra-natural” selection will occur. What can be considered to be a survival strategy in natural circumstances – blue light indicates clear open water and hence potential detection by fish – has quite a different meaning in this set-up: it is exactly those water fleas that do not swim away from the blue light that survive and reproduce. However, fish are residing in the lower sections of the aquaria and most of the water fleas are immediately wiped out. The water fleas are repelled by this color of light, flee downwards and pass through holes in a false bottom in the aquaria. Whenever a visitor approaches the installation and passes a wall-mounted sensor, blue spotlights on the top of the aquaria are activated. The water fleas are strongly attracted to this light and swim in close proximity to it, near the surface of the water. When the system is in standby, yellow lights illuminate the aquaria from the top. The whole system is designed in such a way that visitors drastically induce a gradual microevolution of the – genetically determined – light-responsive behavior of the water fleas. Using single-cell algae, water fleas, fish and water snails, a compact aquatic community is set up in the exhibition space. The project was originally conceived for the exhibition ‘Hot Re-Strike’ (curated by Stef Van Bellingen) in the De Warande arts centre in Turnhout, Belgium in 2005.īlue Shift is an interactive installation with a living model ecosystem at its core.
