UNITARY GROUPS: REPRESENTATIONS AND DECOMPOSITIONS
An elementary account is given of the representation theory for unitary groups. We review the basic definitions and the construction of irreducible representations using tensor methods, and indicateExpand

Hooke, orbital motion, and Newton's Principia
A detailed analysis is given of a 1685 graphical construction by Robert Hooke for the polygonal path of a body moving in a periodically pulsed radial field of force. In this example the force variesExpand

Thermal effects of laser radiation in biological tissue.
A theoretical model is presented that simulates the thermal effects of laser radiation incident on biological tissue. The multiple scattering and absorption of the laser beam and the thermalExpand

Calculated fusion rates in isotopic hydrogen molecules
COLD fusion occurs when two nuclei with very small relative energy tunnel through their mutual Coulomb barrier to initiate a nuclear reaction. The phenomenon is well studied in muon-catalysedExpand

Essay Review: The Mathematical Principles Underlying the Principia Revisited: The Key to Newton's Dynamics: The Kepler Problem and the Principia, Newton's Principia: The Central Argument
In the Preface of the Principia Newton outlines one of his main goals: "that from the phenomena we may investigate the forces of nature, and then from these forces we may demonstrate the rest of theExpand

Max Planck and the birth of the quantum hypothesis
Based on the functional dependence of entropy on energy, and on Wien's distribution for black-body radiation, Max Planck obtained a formula for this radiation by an interpolation relation that fittedExpand

Conical tip in frozen water drops
A theory is presented for the formation of a conical tip in water drops that are frozen on a flat surface below freezing temperature. For the known ice to water density ratio r = .917, the angle ofExpand
