Hello,
Something I've wondered about for some time is what happens to units once we pump them into a exponential or log function.
For example in neutron attenuation
I(x) = I_0 * exp(-Sigma * x)
I feel like this something I should know, but I just don't get it.
I suspect what's happening is that the units stay the same since basically all the function is doing is changing the magnitude of the scalar quantity associated with the unit, and not necessarily what the unit measures.
If that's so is there a word I can use to describe a function that does change a inputs unit (such as the aformentioned) and one that does not?
