The wave-particle duality is one of those essential pillars. Physics courses devote weeks to just introducing it – but there are still important aspects that can be covered in a short article.

Prolate Spheroidal Wave Functions (PSWFs): Special functions optimised for representing band‐limited signals, providing an orthogonal basis with excellent time–frequency localisation.

Meteorologists are constantly monitoring "tropical waves," but what exactly is a tropical wave and why are they watched so closely? We know from experience tropical waves seem to precipitate ...
