I am interested in superfluid ^{3}He because it is
one of a small number of systems that satisfy all the following
conditions.

- It exists in nature.
- One can study it experimentally. The experimental results can be reproduced.
- It shows nontrivial phenomena. In fact, there is a great number of them.
- There exists a powerful theory which provides quantitative understanding for most experimental results and predicts many phenomena. This is the quasiclassical theory of Fermi liquids.

Note that this is my personal view, and Grigory Volovik has a somewhat different emphasis in his research.
