Perhaps you should try some spelling variations:
continuous particle » continuous martingales, continuous parameter
continuous physics » continuum physics, continuous phase, continuous passive
continuum » continued, continues

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((continuous physics) OR (continuous particle))) OR ((continuum OR continue) physics)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((continuous physics) or (continuous particle))) or ((continuum OR continue) physics))".
• Adding a wildcard symbol may retrieve word variants: ((((continuous physics) or (continuous particle))) or ((continuum OR continue) physics))*.
