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

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