I am proud that my work “Brouwer’s problem on a heavy particle in a rotating vessel: wave propagation, ion traps, and rotor dynamics” has been one of the sources of inspiration for the organizers of the International Young Physicists Tournament IYPT 2014 that took place 3rd till 10th of July 2014 in Shrewsbury, United Kingdom.
