Simulation of Newton's Cradle, a device consisting of several steel balls suspended from a cage. Uses the 2D Rigid Body Physics Engine. Each ball acts like an individual pendulum. At rest all the balls are touching.
It was essential to remind people that all the matter around us has one base unit: the atom. Dalton thought it was important to use his system of symbols for the representation of chemical elements because it was helpful to remember exactly which atoms lay at the basic structure of the matter. It was easy for people to use symbols for elements in chemical formulas. He pictured the atoms as small balls and this is the same way that he depicted models of elements and compounds.
Considered to be the father of âmodern atomic theoryâ, John Dalton was also a pioneer of weather forecast and was one of the first scientists to use homemade instruments to make weather observations. Much of his early works and observations using meteorological instruments laid the foundation for the study of weather forecasting. His fascination for the weather and atmosphere lead him to pursue research on âthe nature of gasesâ, which in turn laid the ground on which he built the âatomic theoryâ.
