You should be using a dimensionless vector.
Dimensionless numbers are the opposite of a smell - they are the most pristine, fresh quantities you can get in physics.
You usually want to express everything you possibly can in a dimensionless way. It tends to make the math a lot simpler and to punch to the heart of the problem.
- awill88 5y agoYou talk about math like it’s poetry … can it really be that artistic of a practice? I suppose that’s how I view writing software.. What is an example of dimensionless numbers?

- wyager 5y agoI would put dimensionality more in the purview of physics than pure math, and at that point it might be more reverse engineering than poetry. Fine structure constant, quantum phase, angles, e, pi are all dimensionless.
