An Electron flies above a metal grating without touching it.
As the electron passes, each groove scatters its electromagnetic near field at a slightly different time. The emissions interfere and produce what's called Smith-Purcell radiation.
This effect is being explored for tunable Terahertz radiation, biomedical spectroscopy, and high-speed communications.
This is a visualization of a Rydberg wavepacket.
In simple terms it is a way of showing an electron in a very highly excited quantum state. The Math comes from the Schrödinger equation for hydrogen where the electron is described by a wavefunction rather than as a tiny ball moving on a fixed path.
The yellow sphere at the centre is the proton, not the electron. The colored 3D surface around it shows places where the electron is more likely to be, i.e. a probability cloud.
You can take your pompous code of conduct and send it into the sun. It was the CoC legalese and weasel language that armed the woke inquisition in the last turning. Never again.
