Izeki Tomotoki (井関 知辰) of
Osaka publishes Sampo-Hakki (算法発揮), in which he gives the
resultant and the
Laplace expansion of the
determinant for the n×n case. At about this date, Tanaka Yoshizane (田中 由真) also describes and applies the resultant, in Sampo-Funkai (算法紛解).
French physicist
Denis Papin, while in
Leipzig and having observed the mechanical power of atmospheric pressure on his 'digester', builds a working model of a
reciprocatingsteam engine for pumping water, the first of its kind, though not efficient.
