We demonstrate the Doppler Effect where a traveling transmitter excites spherical waves in fixed time intervals. While a frequency increase in the direction of travel is observed, a reduction of frequency occurs in the opposite direction.

Why Do Physicists Believe In These Particles That DON'T Exist? Quasiparticles by Parth G
The answer: these "Quasiparticles" make physics much easier to study! In this video we'll be studying 3 quasiparticles (sometimes known as collective excitations). They don't actually exist, in that they are not fundamental particles themselves, but can be thought of as mathematical simpl

Ahlfors-Bers 2014 "Rigidity of Teichmüller space"
Kasra Rafi (University of Toronto): We study the large scale geometry of Teichmüller space equipped with the Teichmüller metric. We show that, except for low complexity cases, any self quasi-isometry of Teichmüller space is a bounded distance away from an isometry of Teichmüller space. Our
