Who invented the compass?
The Chinese. The earliest recorded actual use of a magnetized
needle for navigational purposes is to be found in Zhu Yu's
book Pingzhou Table Talks (è��æ´²å�¯è«�; Pingzhou Ketan) of
1119 (written from 1111 to 1117): The navigator knows the
geography, he watches the stars at night, watches the sun at day;
when it is dark and cloudy, he watches the compass. Thus, the
use of a magnetic compass as a direction finder occurred sometime
before 1044, but evidence for the use of the compass as a
navigational device did not appear until 1119.
The mathematical compass was invented by Galileo
