A student society at a university campus decides to create a pool of bicycles that can be used by its mem- bers. Borrowed bicycles can be returned to the resi- dence, the library, or the athletic centre. On the first day, 200 marked bicycles are left at each location. At the end of the day, at the residence, there are 160 bicy- cles that started at the residence, 40 that started at the library, and 60 that started at the athletic centre. At the library, there are 20 that started at the residence, 140 that started at the library, and 40 that started at the athletic centre. At the athletic centre, there are 20 that started at the residence, 20 that started at the library, and 100 that started at the athletic centre. If this pat- tern is repeated every day, what is the steady-state dis- tribution of bicycles?

In quantum mechanics, a Hermitian operator is defined through the operation of the Hermitian adjoint. The Hermitian adjoint of an operator \(\hat{A}\) is termed \(\hat{A}^\dagger\) and is defined by \(\langle \phi | \hat{A} \psi \rangle = \langle \hat{A}^\dagger \phi | \psi \rangle\). \(\hat{A}\) is a Hermitian operator if \(\hat{A} = \hat{A}^\dagger\), or \(\langle \phi | \hat{A} \psi \rangle = \langle \hat{A} \phi | \psi \rangle\). Consider the following operator \(\hat{A}\), \(\hat{A} \phi(x) = \phi^*(x)\). a) Is \(\hat{A}\) Hermitian? b) What are the eigenfunctions of \(\hat{A}\)? c) What are the values of \(\hat{A}\)?
