The verticalvibrationof a rigid circular footing resting on a single-layeredsaturatedground is studiedby employing the method of Hankeltransformandintegralequation.
Although the theory that describes the interaction of quarks and gluons is on a firm conceptual footing, it is so complicated in practice that it can take years to make a single calculation of something like the shape of a proton even using the most powerful supercomputers.
