I don’t deal with sound waves but in my field phonons are absolutely a mathematical trick. With some materials, you need more than just a photon to produce the photo electric effect, you also need a phonon which is in this case, a quantized amount of momentum. Phonons are a virtual Particle and therefore aren’t really existing.

Pantone colors aren't just generic colors like red, yellow, or blue. They are very specific and standardized, which makes them useful in color dependent professions like graphic design or interior design. As a commercial architecture an interiors photographer, I have specifically asked my clients for their colors to ensure that the pictures I deliver to them are a perfect match.

The colors can be licensed because they are someone's intellectual property. In fact, they were already being licensed to Adobe by Pantone, but Pantone got upset because Adobe wasn't keeping these very specific colors up to date in their software.

Here's an article from the popular photography website PetaPixel about the issue:

> If the central bank creates money faster than the amount of goods and services is growing, then all prices will rise, in roughly the same proportion.

A small correction here: most money these days is created by private banks, not by the central bank. Part of the idea here is that it makes the money supply more responsive to demand - when there's lots of demand for borrowing, banks will create more money.

Central banks do have the main responsibility for overseeing this though, and can influence the money supply via interest rates and regulation.

Phonons are often used in situations where you're analysing things at a quantum level, where wave-particle duality kicks in - particles can be more accurately modeled as waves, and visa versa, depending on the scenario in question - and for reasons that I don't understand well enough to ELI5 this applies to sound waves, which are therefore also particles.
