• •Nature uses complex numbers in Schrödinger’s equation and quantum ﬁeld theory. This is not a mere mathematical convenience or sleight-of-hand, but in fact appears to be a built-in feature of the very equations describing our physical universe. Why? No one knows. •Conformal maps, which come up in purely geometric applications where
• In particular, I like Liboff's discussion on good/bad quantum numbers and the matrix representation of quantum mechanics. The corresponding discussion in Griffiths is really lacking. My main complaint regarding Liboff is that some sections seem to be out of context, in particular the last few sections in chapter 7, 8 and 11.

• In hydrogen atom, the permissible energy level is described by four quantum numbers – principal quantum number, angular momentum quantum number, magnetic quantum number and spin quantum number. According to general law of nature, a physical system has maximum stability in its lowest energy state.

• Quantum numbers may be defined as a set of four numbers with the help of which we can get complete information about all the electrons in an atom. It tells us the address of the electron i.e., location, energy, the type of orbital occupied and orientation of that orbital.

Quarks have the additive baryon number 1/3, antiquarks -1/3. Table 14.1 gives the other additive quantum numbers (ﬂavors) for the three generations of quarks. They are related to the charge Q (in units of the elementary charge e) through the generalized Gell-Mann-Nishijima formula Q = Iz + B +S+C+B+T 2, (14.1) where B is the baryon number.
