"Lists of moons" typically refer to compilations or tables that catalog the natural satellites (moons) orbiting planets and other celestial bodies in the solar system and beyond. These lists can be organized in various ways, such as by the planet they orbit, size, discovery date, or other characteristics. Here are some common points of interest related to lists of moons: 1. **By Planet**: Moons are often grouped by the planets they orbit.

Back pressure is a term used in various fields, notably in engineering and fluid dynamics, to describe a situation where resistance or pressure within a system prevents or slows down the movement of fluids or gases. It can occur in different contexts, such as: 1. **Fluid Systems**: In pipelines or hydraulic systems, back pressure is the pressure exerted in the opposite direction of the flow. It can be caused by factors such as narrowing of pipes, obstructions, or changes in elevation.

Probability Bounds Analysis (PBA) is a quantitative method used in decision-making and risk analysis that helps assess uncertainty in probabilistic models. It is particularly beneficial when precise probability distributions are difficult to obtain, and instead, one may only have limited information about the underlying uncertainties. PBA uses interval probability distributions to represent the uncertainties and derive bounds on the probabilities of various outcomes.

Fritz Strassmann was a German physicist who is best known for his work in nuclear chemistry and for his role in the discovery of nuclear fission. He was born on February 22, 1902, and passed away on April 22, 1980.

John N. Bahcall (1934–2005) was a prominent American astrophysicist known for his significant contributions to the fields of solar and particle astrophysics. He was particularly recognized for his influential work on the solar neutrino problem, which involved studying the neutrinos produced by nuclear reactions in the Sun's core and their detection on Earth. Bahcall's theoretical predictions about the number of neutrinos expected to be detected were crucial for understanding the processes occurring in the Sun.

In the context of Wikipedia, a "stub" is a small, incomplete article that provides some basic information about a topic but lacks detailed content. A "Mathematical logic stub" refers specifically to a brief article related to the field of mathematical logic that needs further expansion and development. Mathematical logic itself is a subfield of mathematics and philosophy that focuses on formal systems, proof theory, model theory, set theory, and computability, among other areas.

Logical truth refers to statements or propositions that are true in all possible interpretations or under all conceivable circumstances. In formal terms, a logical truth is typically a statement that can be proven to be true through logical deduction and does not depend on any specific facts or empirical evidence. One classic example of a logical truth is the statement "If it is raining, then it is raining." This statement is true regardless of whether or not it is actually raining because it holds true based solely on its logical structure.
