what is a phenomenological field?

Question

is there such a thing at all?

reply to throw_some_shapes: lol, dont worry about it, it's my fault i didn't pay attention in school lol x

Answer 1

Phenomenology isn't a field in itself. Phenomenology exists within fields. Its what you get when you ask the question:

So what are the implications of our theories in the real world? What phenomenon will we observe?

So there's particle phenomenology (see the link to the particle phenomenology center at U Wisconsin), solid state, plasma, you name it.

Sometimes you'll hear people say stuff like "Grad students today are weak in their phenomenology." What they mean is that the students have their noses so deep in their books and are so up to their eyeballs in equations and mathematical techniques, that they don't see the forest for the trees. They don't understand the real-world consequences of the stuff they are studying.

Philosophers also use the term and may mean something slightly different by it than physicists do.

Answer 2

You probably mean field as in an electric field (as opposed to a field of study like entomology). A phenomenological property in physics is one which cannot at present be derived from first principles, but must instead be determined experimentally. Often the model itself which invokes that property is itself contrived to fit the data. This is generally due to lack of complete understanding or computational complexities required otherwise. A field, meanwhile is a spatial or spatiotemporally distributed property (like density).

An example of a phenomenological field would be the stress tensor of a solid based on a simplified elastic-plastic material strength model that seems to work for that material, and for which the parameters of the model (such as elastic modulus) are simply measured on a bench-test.

Answer 3

i feel rilly bad u always answer my quesions but i never no the answer to urs so cant answer them... but the answer 2 ur question is above and below(apparently) this makes me feel even better stuck in the middle of the answer lol..xx
