How can the ladder operators be used to determine the eigenvalues of the x operator in quantum mechanics?
In quantum mechanics, the ladder operators can be used to determine the eigenvalues of the x operator by applying them to the wavefunction of the system. The ladder operators raise or lower the eigenvalues of the x operator by a fixed amount, allowing us to find the possible values of x for which the wavefunction is an eigenfunction. By repeatedly applying the ladder operators, we can determine the eigenvalues of the x operator for a given system.

What is a Hermitian operator?
A Hermitian operator is any linear operator for which the following equality property holds: integral from minus infinity to infinity of (f(x)* A^g(x))dx=integral from minus infinity to infinity of (g(x)A*^f(x)*)dx, where A^ is the hermitian operator, * denotes the complex conjugate, and f(x) and g(x) are functions. The eigenvalues of hermitian operators are real and their eigenfunctions are orthonormal.

Why time isn't an operator in quantum mechanics?
Associated with each measurable parameter in a physical system is a quantum mechanical operator. Now although not explicitly a time operator the Hamiltonian operator generates the time evolution of the wavefunction in the form H*(Psi)=i*hbar(d/dt)*(Psi), where Psi is a function of both space and time. Also I don't believe that in the formulation of quantum mechanics (QM) time appears as a parameter, not as a dynamical variable. Also, if time were an operator what would be the eigenvalues and eigenvectors of such an operator? Note:A dynamical time operator has been proposed in relativistic quantum mechanics. A paper I found on the topic is; Zhi-Yong Wang and Cai-Dong Xiong , "Relativistic free-motion time-of-arrival", J. Phys. A: Math. Theor. 40 1987 - 1905(2007)
Eigenvalues of an operator are the only experimentally measurable quantities?
Is an axiom of Quantum Mechanics. The implications are extremely subtle and mathematical, so I recommend reading the quantum books by Shankar or Griffiths. Both should be available at any technical or university library.
