After giving the reader a basis of understanding of astrophysics and particle physics, in chapter 5, Weinberg lays out the makeup of the Universe after its origin in a series of frozen frames. Weinberg shows how the Big Bang can account for the relative abundance of Hydrogen and Helium in the universe. Late in the book...

The desire for a large infrared space telescope traces back decades. In the United States, the Space Infrared Telescope Facility (later called the Spitzer Space Telescope) was planned while the Space Shuttle was in development, and the potential for infrared astronomy was acknowledged at that time.

It may also be used for the kinetic energy or potential energy of a body. Specific energy is an intensive property, whereas energy and mass are extensive properties. The SI unit for specific energy is the joule per kilogram (J/kg). Other units still in use in some contexts are the kilocalorie per gram (Cal/g or kcal/g)...

The Coppersmith method, proposed by Don Coppersmith, is a method to find small integer zeroes of univariate or bivariate polynomials modulo a given integer. The method uses the Lenstra–Lenstra–Lovász lattice basis reduction algorithm (LLL) to find a polynomial that has the same zeroes as the target polynomial but small...

Like crude oil, APG is both a primary energy resource and a primary commodity that enables much of the modern world economy. Statistics from the International Energy Agency show that the natural-gas supplies steadily increased during 1990-2017 to meet the demands of expanding global population and consumerism. APG is n...
