Example 1 — tin oxides: Dalton identified two types of tin oxide. One is a grey powder that Dalton referred to as "the protoxide of tin", which is 88.1% tin and 11.9% oxygen. The other is a white powder which Dalton referred to as "the deutoxide of tin", which is 78.7% tin and 21.3% oxygen.
Person/s considered "father" or "mother" Rationale Chaos theory: Henri Poincaré [192] Mary Cartwright [193] [194] Edward Lorenz [195] Poincaré's work on the three-body problem was the first discovered example of a chaotic dynamical system. Cartwright made the first mathematical analysis of dynamical systems with chaos.

John Dalton's union of atoms combined in ratios (1808) Similar to these views, in 1803 John Dalton took the atomic weight of hydrogen, the lightest element, as unity, and determined, for example, that the ratio for nitrous anhydride was 2 to 3 which gives the formula N 2 O 3. Dalton incorrectly imagined that atoms "hooked" together to form ...
