Works & Achievements
A text clearly explaining the geometry of lunar eclipses, based on her experiments with a lamp and a mirror; it challenges superstitious interpretations.
A five-volume work devoted to mathematics, in which she presents methods of multiplication and division in an accessible way.
A rewriting in plain language of Mei Wending's mathematical writings, reputed to be difficult, in order to make them understandable to beginners.
A study explaining the slow shift of the equinoctial points, a complex astronomical subject that she made accessible to the educated public.
A collection of poems and essays preserved in thirteen volumes, in which she addresses science, travel, and intellectual equality between women and men.
A demonstration explaining why people living on the other side of the globe do not fall off, incorporating the contributions of astronomy that had come from Europe.
Anecdotes
To understand lunar eclipses, Wang Zhenyi carried out an experiment in a garden pavilion: she hung a lamp to stand for the Sun, placed a round table on the floor to represent the Earth, and moved a round mirror as if it were the Moon. By shifting these objects around, she faithfully reproduced the geometry of eclipses, which she then explained in a clear text.
Largely self-taught, she learned astronomy and mathematics by devouring the vast library inherited from her grandfather, a high-ranking scholar-official. She supplemented her reading with direct observation of the sky, at a time when women were mainly expected to keep house.
Convinced that intelligence has no sex, she argued in her poems that girls and boys are equally capable of study. This stance was bold in Qing China, where scholarly education remained an almost entirely male privilege.
The writings of the famous mathematician Mei Wending were known to be very difficult. Wang Zhenyi rewrote them in plain language so that beginners could understand them, becoming one of the first popularizers of science in her country.
Having died at only 29, she entrusted her manuscripts to a close friend, Madame Kuai, before passing away. It is thanks to this transmission between women that part of her work, notably her collection *Defengting Chuji*, has come down to us.
Primary Sources
We are made to believe that women are not worth as much as men; but are you not convinced that girls too can be heroic?
When the Earth places itself exactly between the Sun and the Moon, its shadow conceals the Moon: this is the eclipse, which is no omen but obeys a regular law.
Study is not a matter of men or women: all, boys and girls, possess the same reason for learning.
