Perhaps you should try some spelling variations:
"during popular science" » "using popular science", "during ocular science", "doing popular science"
"during polar science" » "during color science", "during power science", "during polymer science", "during solar science"

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: "((\"during popular science\") OR (\"during polar science\"))*".
• Removing quotes may allow a broader search: (( during popular science ) OR ( during polar science ))*.
