Please try to include the following

• main points understood, and expand them - what is your understanding of what the points were.
  • expand these points by including many of the details the class discussed.
• main points which are not clear. - describe what you have understood and what the remain questions surrounding the point(s).
  • Other classmates can step in and clarify the points, and expand them.
• How the main points fit with the big picture of QM. Or what is not clear about how today's points fit in in a big picture.
• wonderful tricks which were used in the lecture.

What is the big picture? Why do we do the math?
<math>\chi_+</math> = <math>$\begin{pmatrix} 1\\ 0\end{pmatrix}$</math>
<math>\chi_-</math> = <math>$\begin{pmatrix} 0\\ 1\end{pmatrix}$</math>
<math>|“m”| =< l</math>
S_e,p,n,q,nu = 1/2 is an intrinsic property that doesn't change. You can just say S_z,m_s,m = +/- 1/2 <math>\hbar</math>.
