How does a kettle know when the water is boiled? When a kettle is plugged into an electric outlet and switched on the electric current flows through a metal coil, which is situated either within or under the water. Because a kettle is a sealed unit, the temperature rises quickly within and pretty soon the […]
What does discretization mean?
What does discretization mean? : the action of making discrete and especially mathematically discrete. Why is discretization needed? Discretization is required for obtaining an appropriate solution of a mathematical problem. It is used to transform the initially continuous problem which has an infinite number of degrees of freedom (e.g. eigenfunctions, Green’s functions) into a discrete […]
