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

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 ("mathematicss" OR "mathematicals")).
• Removing quotes may allow a broader search: ( mathematician or ( mathematicss or mathematicals )).
• Adding a wildcard symbol may retrieve word variants: ("mathematician" or ("mathematicss" or "mathematicals"))*.
