==Mathematics==
The [[Mohist canon]] (''Mo Jing'') described various aspects of many fields associated with physical science, and provided a small wealth of information on mathematics as well. It provided an 'atomic' definition of the geometric point, stating that a line is separated into parts, and the part which has no remaining parts (i.e. cannot be divided into smaller parts) and thus the extreme end of a line is a point.{{Sfn |Needham|1986 | p = 91}}  Much like [[Euclid]]'s first and third definitions and [[Plato]]'s 'beginning of a line', the ''Mo Jing'' stated that "a point may stand at the end (of a line) or at its beginning like a head-presentation in childbirth. (As to its invisibility) there is nothing similar to it."{{Sfn |Needham|1986 | p = 92}} Similar to the [[atomist]]s of [[Democritus]], the ''Mo Jing'' stated that a point is the smallest unit, and cannot be cut in half, since 'nothing' cannot be halved.{{Sfn |Needham|1986 | p = 92}}  It stated that two lines of equal length will always finish at the same place,{{Sfn |Needham|1986 | p = 92}} while providing definitions for the ''comparison of lengths'' and for ''parallels'',{{Sfn |Needham|1986 | p = 93}} along with principles of space and bounded space.{{Sfn |Needham|1986 | p = 93}}  It also described the fact that planes without the quality of thickness cannot be piled up since they cannot mutually touch.{{Sfn |Needham|1986 | pp = 93–94}}  The book provided definitions for circumference, diameter, and radius, along with the definition of volume.{{Sfn |Needham|1986 | p = 94}}
