Matrix
[tex]
\left[
\begin{array}{rr}
1 & 1 \\
0& 0 \\
\end{array} \right][/tex]
is not symmetric. When we find eigenvalues of that matrix we get ##\lambda_1=1##, ##\lambda_2=0##, or we get matrix
[tex]
\left[
\begin{array}{rr}
1 & 0 \\
0& 0 \\
\end{array} \right][/tex].
First matrix is not hermitian, whereas second one it is. How it is possible that some operator is hermitian in one basis, and is not in the other one. Second matrix is also a projector, and the first one it is not. How that is possible.
