Superfluids

Superfluid

The definition of a superfluid is:  "a fluid that exhibits frictionless flow, very high heatconductivity, and other unusual physical properties, heliumbelow 2.186 K being the only known example."

From:  http://dictionary.reference.com/browse/superfluid

"We derive the Josephson relation in a superfluid between the condensate density, the superfluid mass density, and the infrared structure of the single particle Green's function by means of diagrammatic perturbation theory. The derivation is valid for finite systems and two dimensions."

Endotherm experiment: By Ansley and Nora

This is Nora and I explaining what we will be doing with our experiment.  There will be another two post of us doing our experiment and then saying what happened and why that did happen.

Last Part of Test 1

It is a little difficult to see in this video but here is me explaining what everything is in our peach pit model by alyssa, elizabeth sexton, and me.
