correction remark pic synchrotronEdit
Thanks for the suggestions of corrections, I've only changed the spelling as I don't know enough about the subject, please feel free to do it, the description was directly copies from the Science Museum info, I'll ask someone to check it.
Thank you for your nice feedback about lightmill - radiometer animation. The one I used is actually a cheap one with old look from Amazon.com. I had the chance to play with one in high school and bought this one for my daughter since the school lab did not had one and Amazon price was affordable. Although I still own the object, unfortunately I sell the camera I used for high speed (240fps) capture. The camera I own now shoots at a lower speed and resolution. Thank you again.
