Just uploaded a copy of the software PyTrA I have been writing in python to analyse ultrafast transient absorption data in the Photon Factory. It is a first release and I am still working on making it easier to use but here is the current version.

Go to the blog post to download the files.

Peter the head engineer in the lab built a nice demonstration of wave motion in a multi-pendulum set-up where each pendulum has a different period leading to a 50s cycle. We are planning on building a larger demo which should reduce the frictional effects for the shorter period pendulums.

For a good write up on the physics behind this demo and how to make your own go to this link

A computer generated demo that helps you hear the patterns.

Congratulations to Sarah Thompson from the photon factory for getting into the finals of the 3min thesis competition.
