De Moivre's law, also known as De Moivre's theorem, is a principle in probability theory, particularly related to the distribution of binomial outcomes. Named after the French mathematician Abraham de Moivre, it states that as the number of trials in a binomial experiment increases, the binomial distribution approximately approaches a normal distribution. Mathematically, the law can be expressed in terms of the central limit theorem.
Amber is a fossilized tree resin that has been appreciated for its beauty and durability for millions of years. It often features a warm, yellow to orange-brown coloration, although it can come in other hues as well, including green, blue, and even white. Amber is notable for sometimes containing inclusions of prehistoric organisms, such as insects, spiders, and plant material, which were trapped in the resin before it hardened.
Sky brightness refers to the amount of light emitted or scattered in the atmosphere that contributes to the illumination of the night sky. It is an important factor in astronomy and outdoor activities, as it can significantly affect visibility and the ability to observe celestial objects. Sky brightness can be influenced by several factors: 1. **Natural Light Sources**: This includes light from the moon, stars, and other celestial bodies. The brightness of the moon during different phases can dramatically change the overall illumination of the night sky.

The Teller-Ulam design is a foundational concept in nuclear weapon design that describes a configuration for thermonuclear weapons, commonly known as hydrogen bombs. The design was developed in the early 1950s and is named after its principal architects, physicist Edward Teller and mathematician Stanislaw Ulam. ### Historical Context 1. **Early Nuclear Weapons (1940s)**: The first nuclear weapons, developed during World War II under the Manhattan Project, were fission bombs (atomic bombs).
