Rutherford scattering cross-section is strongly peaked around zero degrees, and yet has nonzero values out to 180 degrees. This formula predicted the results that Geiger measured in the coming year. The scattering probability into small angles greatly exceeds the probability in to larger angles, reflecting the tiny nucleus surrounded by empty ...
Allowing Social Security to slash benefits would likely plunge an untold number of seniors into poverty. And Medicare cuts could be devastating in their own right, whether they come in conjunction ...
The Cyrus Cylinder is an ancient clay cylinder, now broken into several pieces, on which is written an Achaemenid royal inscription in Akkadian cuneiform script in the name of the Persian king Cyrus the Great. [2][3] It dates from the 6th century BC and was discovered in the ruins of the ancient Mesopotamian city of Babylon (now in modern Iraq ...
Material: vellum: Size: ≈ 23.5 cm × 16.2 cm × 5 cm (9.3 in × 6.4 in × 2.0 in) Format: One column in the page body, with slightly indented right margin and with paragraph divisions, and often with stars in the left margin; [12] the rest of the manuscript appears in the form of graphics (i.e. diagrams or markings for certain parts related to illustrations), containing some foldable parts
An enacting clause is a short phrase that introduces the main provisions of a law enacted by a legislature. It is also called enacting formula or enacting words. [ 1 ] It usually declares the source from which the law claims to derive its authority. In many countries, an enacting formula is not considered necessary and is simply omitted.
Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, electric and magnetic circuits. The equations provide a mathematical model for electric, optical, and radio technologies, such ...
The Keys to the White House. The Keys to the White House is a prediction system for determining the outcome of presidential elections in the United States. It was developed by American historian Allan Lichtman and Russian geophysicist Vladimir Keilis-Borok in 1981, adapting prediction methods that Keilis-Borok designed for earthquake prediction.
The Andromeda Galaxy is known to harbor a dense and compact star cluster at its very center, similar to our own galaxy. A large telescope creates a visual impression of a star embedded in the more diffuse surrounding bulge. In 1991, the Hubble Space Telescope was used to image the Andromeda Galaxy's inner nucleus.
