Why build a Foucault pendulum?
The idea to build a Foucault pendulum on our school arose at a visit in Magdeburg in Germany. In an exhibition of famous scientific experiments, Jahrtausendturm, among other things a Foucault pendulum was built.
The pendulum at Carlsund from the beginning was aimed to be built within the frame of the syllabus for a special project course. The idea was that the different programs in the school should co-operate to build a Foucault pendulum. The project was to be divided into different under-projects in a natural way. Unlike many projects this project would leave something lasting, that is, a pendulum. Carlsund is a school with possibility to learn about industry-, electronics, building and technical science.
This is the way it was aimed to be:
Unfortunately it was not possible to make a project within the frame of the project course, but the pendulum that today hangs at the entrance of Carlsund is constructed at the industry and electronic programmes.
It took about a year to make a working electronics that adds some energy at each swing to make the pendulum keep on moving. With a working electronic the project could start in real, drawings with details could be constructed and thereafter the production could get started.
The result of the project was a fantastic Foucault pendulum that works exactly in accordance with theory. I will recommend this experiment to everybody who has an opportunity to do something like this. It is the most fascinating experiment I have ever made. It is a work of art and at the same time a classical, conspicuous experiment.
