    The unknown part of the equation is y(x+Δx), which can be found if we have the data for the initial values. Runge-Kutta methods → it is more accurate than the Euler method. In this method, an initial condition is required: y = y 0 at x = x 0. The problem is to find the value of y when x = x 0 + h, where h is a given constant.

    en.wikipedia.org/wiki/Chinese_remainder_theorem

    In mathematics, the Chinese remainder theorem states that if one knows the remainders of the Euclidean division of an integer n by several integers, then one can determine uniquely the remainder of the division of n by the product of these integers, under the condition that the divisors are pairwise coprime (no two divisors share a common factor other than 1).

    A wavelet is a wave-like oscillation with an amplitude that begins at zero, increases or decreases, and then returns to zero one or more times. Wavelets are termed a "brief oscillation".

  8. Magnetic levitation - Wikipedia

    en.wikipedia.org/wiki/Magnetic_levitation

    In practice many of the levitation schemes are marginally stable and, when non-idealities of physical systems are considered, result in negative damping. This negative damping gives rise to exponentially growing oscillations around the magnetic field's unstable equilibrium point, inevitably causing the levitating object to be ejected from the ...
