Perhaps you should try some spelling variations:
"classical and continue physics" » "classical and continuum physics", "classical and continuum phyisics", "classical and cone physics"
"classical and continue his" » "classical and continue till", "classical and continue _"
"classical and continue a" » "classical and continue _"

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