Richard Swineshead (or Suiseth or Suisset, fl.1340-54) was a mathematician and natural philosopher, and a member of the Oxford Calculators at Merton College.

The incipit of Liber calculationum (c.1350) calls it a very useful golden book on calculations which can be applied to all the sciences . Swineshead presupposes an Aristotelian/Neoplatonic physics, and searches for a logically adequate, mathematically precise account of it . He considers imaginary, physically impossible cases as long as they are not logically contradictory (Longeway, p.468). The 12 chapters begin by analysing the degrees of qualities (intension and remission), e.g. heat, according to whether their degree is uniform or not uniform; rarity and density (I.e., the proportion of quantity of matter to volume ); the power of an action (maximum and minimum) and of resistance when a body interacts with another; the movement of a body towards the centre of the
