How do I compute range in a likert scale with 0 to 4?

If you use a likert scale with range "never" as 0, 1 is "one to two times", 2 is "sometimes", 3 "often" and 4 "most of the time". How to correctly compute the range? Is the lowest value counted?...

How to correctly describe and model the diffuse reflectance measured from a set of optical fibers in skin?

There are different approaches to diffuse reflectance modeling, most of them based on the solution of the radiative transport equation by the diffusion-based approximation. However, a set of fiber...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
