Perhaps you should try some spelling variations:
"mathematician" » "mathematical", "mathematics"
"mathematicians" » "mathematicals", "mathematicss", "mathematics", "mathematical"
"mathematicals" » "mathematical", "mathematically", "mathematics"
"mathematicans" » "mathematiciens", "mathematics", "mathematical"

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