Perhaps you should try some spelling variations:
"radio science theories 1:, mathematics, physics and chemistry" » "radio science three 1:, mathematics, physics and chemistry", "radio science theories 3:, mathematics, physics and chemistry", "radio science theories 4:, mathematics, physics and chemistry"
"radio science stories 1:, mathematics, physics and chemistry" » "radio science studies 1:, mathematics, physics and chemistry", "radio science series 1:, mathematics, physics and chemistry", "radio science stories 14:, mathematics, physics and chemistry", "radio science stories 12:, mathematics, physics and chemistry", "radio science stories 10:, mathematics, physics and chemistry"

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: "((\"radio science stories 1:, mathematics, physics and chemistry\") OR (((\"radio science theory ii:, mathematics, physics and chemistry\") OR (\"radio science theories 1:, mathematics, physics and chemistry\"))))".
• Removing quotes may allow a broader search: (( radio science stories 1:, mathematics, physics and chemistry ) OR ((( radio science theory ii:, mathematics, physics and chemistry ) OR ( radio science theories 1:, mathematics, physics and chemistry )))).
• Adding a wildcard symbol may retrieve word variants: (("radio science stories 1:, mathematics, physics and chemistry") OR ((("radio science theory ii:, mathematics, physics and chemistry") OR ("radio science theories 1:, mathematics, physics and chemistry"))))*.
