World Quantum Day is celebrated every 14 April, with the numbers taken from Planck's constant, 4.14 × 10⁻¹⁵ electron-volts per second. This constant is central to understanding how energy behaves at microscopic scales, governing everything from atomic interactions to light absorption.
At first, it all seems more like a physics lesson. However, quantum mechanics has become more than that, which is why it has now gone as far as being included in public discussions.
