Archimedesn.

/ɑːkɪˈmiːdiːz/

Forms: Also anglicized Archimede /ˈɑːkɪmiːd/.

Etymology: Greek proper name.

A philosopher of Syracuse, celebrated for his discoveries in applied mathematics and mechanics, and for his statement, that with a lever long enough and a point to stand upon he could move the world. (Here used connotatively.)
