Perhaps you should try some spelling variations:
"classical and continuous physics" » "classical and continuous phase", "classical and continuous passive", "classical and continuous posets"
"classical and continues physics" » "classical and continuum phyisics", "classical and centres physics", "classical and constants physics"
"classical and continuum physics" » "classical and continued physics", "classical and continue physics"

Try widening your search to All Fields.

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: (("classical and continuous physics") OR ((("classical and continuum physics") OR ("classical and continues physics")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"classical and continuous physics\") or (((\"classical and continuum physics\") OR (\"classical and continues physics\"))))".
• Removing quotes may allow a broader search: (( classical and continuous physics ) or ((( classical and continuum physics ) OR ( classical and continues physics )))).
• Adding a wildcard symbol may retrieve word variants: (("classical and continuous physics") or ((("classical and continuum physics") OR ("classical and continues physics"))))*.
