At the conclusion of Compton's 1923 paper, he reported results of experiments confirming the predictions of his scattering formula thus supporting the assumption that photons carry directed momentum as well as quantized energy.

At the beginning of 2011, Classic Rock magazine gave ten predictions for the year.

At the time, various people had expressed concern with Galileo's ideas about falling bodies, arguing that it would be impossible to discern the small differences in time and distance needed to adequately test Galileo's ideas, or reporting that experiments had not agreed with Galileo's predictions, or complaining that suitably tall buildings with clear paths of fall were not available to thoroughly test Galileo's ideas.

At no other period in history was the margin of dominance of one state over others so extensive, making the traditional application of balance of power theory and predictions of balancing behaviour from secondary powers inapplicable.

At its core are Einstein's equations, which describe the relation between the geometry of a four-dimensional, pseudo-Riemannian manifold representing spacetime, and the energy – momentum contained in that spacetime.

At the start of his derivation, he had postulated an expression for the momentum of a photon from equating Einstein's already established mass-energy relationship of to the quantized photon energies of which Einstein has separately postulated.

At the Fifth Solvay Congress, held in Belgium in October 1927 and attended by all the major theoretical physicists of the era, Louis de Broglie presented his own version of a deterministic hidden-variable theory, apparently unaware of Einstein's aborted attempt earlier in the year.

At the sixth Congress of Solvay in 1930, the indeterminacy relation just discussed was Einstein's target of criticism.

D. At this time, Albert Einstein's then new theory of gravitation, the general theory of relativity, was the subject of much enthusiasm among the graduate students, although the faculty was more cautious, apparently feeling out of their depth.

At standard temperature and pressure, oxygen is a very pale blue, odorless gas with the molecular formula, in which the two oxygen atoms are chemically bonded to each other with a spin triplet electron configuration.

It is also the derivative of the formula for the volume with respect to r because the total volume of a sphere of radius r can be thought of as the summation of the surface area of an infinite number of spherical shells of infinitesimal thickness concentrically stacked inside one another from radius 0 to radius r. At infinitesimal thickness the discrepancy between the inner and outer surface area of any given shell is infinitesimal and the elemental volume at radius r is simply the product of the surface area at radius r and the infinitesimal thickness.
