About World Quantum Day
This Doodle celebrates World Quantum Day, an annual celebration that improves understanding of quantum physics and technology. The date, April 14th, represents the first three digits of Planck’s constant, which describes the relationship between the energy and frequency of a quantum of energy (such as a photon): 4.14×10−15 eV·s
The artwork featured in today’s Doodle shows a thaumatrope, a tool and optical toy that consists of a disk with two different pictures on either side. When spun rapidly, our brains superimpose both images so they appear to combine and form one image. The thaumatrope helps illustrate the concept of quantum superposition: when a particle exists in multiple states at once.
