-====== Quantum matrices ======
+===== Quantum matrices =====
 I'll push a bit further with mathematics because there is another important way to describe quantum states: using matrices.\\
 \\
-In the previous chapter we discovered the quantum state with the equation:
+The quantum state <m>delim{|}{psi}{}> = alpha delim{|}{0}{}> + beta delim{|}{1}{}></m> can also be defined with the following matrix:
-;#;
-<m 15>delim{|}{psi}{}> = alpha delim{|}{0}{}> + beta delim{|}{1}{}></m>

-This same state is also defined with the following matrix:
 ;#;
 <m 15>delim{[}{matrix{2}{1}{alpha beta}}{]}</m>

+===== A little detail concerning amplitudes ... =====
+There is a little joke concerning amplitudes: they are complex numbers...No don't leave!!!\\
+It is not a big deal because the most of the time we are using them as normal numbers. \\
+\\
+I wanted to indicate this detail because it shows how crazy quantum world is.
