Perhaps you should try some spelling variations:
"nato science theories b:, physics" » "nato science three b:, physics", "national science theories b:, physics", "nato science theories 3:, physics", "nato science theories 1:, physics", "nato science theories 2:, physics"
"radio science theories b:, physics" » "radio science three b:, physics", "radio science theories 3:, physics", "radio science theories 1:, physics", "radio science theories 2:, physics"
"radio science theories 4:, physics" » "radio science three 4:, physics", "radio science theories 3:, physics"
"nato science theory b:, physics" » "national science theory b:, physics"

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: (((("nato science theories b:, physics") OR ((("radio science theories b:, physics") OR ("radio science theories 4:, physics"))))) OR ("nato science theory b:, physics"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"nato science theories b:, physics\") or (((\"radio science theories b:, physics\") OR (\"radio science theories 4:, physics\"))))) or (\"nato science theory b:, physics\"))*".
• Removing quotes may allow a broader search: (((( nato science theories b:, physics ) or ((( radio science theories b:, physics ) OR ( radio science theories 4:, physics ))))) or ( nato science theory b:, physics ))*.
