Perhaps you should try some spelling variations:
"lecture notes in physics graphs" » "lecture notes in physical graph", "lecture notes in physics games", "lecture notes in physics goals"
"lecture notes in physics glass" » "lecture notes in physics class", "lecture notes in physics mass", "lecture notes in physics goals"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"lecture notes in physics graphs\") OR (\"lecture notes in physics glass\"))".
• Removing quotes may allow a broader search: (( lecture notes in physics graphs ) OR ( lecture notes in physics glass )).
• Adding a wildcard symbol may retrieve word variants: (("lecture notes in physics graphs") OR ("lecture notes in physics glass"))*.
