Quantum gravity is a field of theoretical physics that seeks to unify quantum mechanics, which describes the behavior of particles on the smallest scales, and general relativity, which describes the gravitational force and the structure of spacetime on larger scales. The primary goal of quantum gravity is to develop a coherent framework that explains how gravity operates at the quantum level, where both the effects of quantum mechanics and gravitational effects are significant.

Whole-body counting is a technique used to measure the amount of radioactive material that is present in the human body. This method is primarily used in fields such as nuclear medicine, radiation safety, and health physics to monitor individuals who may have been exposed to radioactive substances, either through occupational exposure or accidental ingestion/inhalation. The process generally involves the use of specialized detectors, such as gamma cameras or scintillation counters, that are sensitive to the specific types of radiation emitted by radioactive isotopes.
Alpha-emitting materials are substances that release alpha particles (helium nuclei) during radioactive decay. These materials can be found in various applications, including medical treatments, smoke detectors, and industrial gauges. Here is a list of some well-known alpha-emitting materials: 1. **Uranium-238 (U-238)**: A common isotope of uranium found in nature, used primarily as fuel in nuclear reactors.

A remote control locomotive is a type of model train or full-scale train that can be operated wirelessly using a remote control device. These locomotives are equipped with a receiver and other electronic components that allow them to respond to signals sent from the remote control, enabling the operator to control movement, speed, and sometimes other functions like lights and sound. **Types:** 1.
Secular equilibrium is a concept in nuclear physics and radiochemistry that describes a situation in a system with multiple radioactive isotopes, where the activity (rate of decay) of a parent isotope is equal to the activity of its daughter isotopes over a long period of time. This occurs when the half-life of the parent isotope is much longer than that of its daughter isotopes.
Civil defense Geiger counters are radiation detection devices specifically designed for use in civil defense and emergency management scenarios. These instruments are utilized to detect and measure ionizing radiation, including alpha, beta, and gamma radiation. Their primary purpose is to help identify radioactive contamination following nuclear accidents, radiological dispersal device (RDD) incidents, or during nuclear warfare events. **Key Features of Civil Defense Geiger Counters:** 1.
An extinct radionuclide refers to a radioactive isotope that was once present in significant amounts in the solar system or on Earth but has now become completely non-existent due to radioactive decay. These isotopes have short half-lives compared to the age of the solar system, leading them to decay completely over time.
Metamictisation is a process that occurs primarily in certain minerals, especially zircon and other uranium-containing silicate minerals, where the crystalline structure becomes disordered due to the accumulation of radiation damage over time. This damage typically results from the decay of radioactive isotopes present within the mineral, such as uranium and thorium. As these isotopes decay, they emit alpha particles and other forms of radiation, which displace atoms in the crystal lattice, leading to a gradual breakdown of the ordered structure.
Particle radiation refers to the emission of particles that are energetic and can carry significant amounts of energy. This type of radiation is typically composed of charged or neutral particles, including: 1. **Alpha Particles**: Consisting of two protons and two neutrons, alpha particles are relatively heavy and have a positive charge. They are emitted during radioactive decay of heavy elements like uranium and radium.
Stanford E. Woosley is a prominent American astrophysicist known for his research in the fields of stellar evolution, supernovae, and nuclear astrophysics. He has made significant contributions to the understanding of how stars explode and the processes involved in the formation of heavy elements in the universe.
Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This process results in the transformation of the original atom (known as the parent isotope) into a different atom or a different isotope of the same element (known as the daughter isotope). Radioactive decay can occur in several forms, including: 1. **Alpha Decay**: The nucleus emits an alpha particle, which consists of two protons and two neutrons (similar to a helium nucleus).
David Jenkinson is a common name, so it could refer to various individuals in different fields such as academia, business, sports, or the arts. Without additional context, it's difficult to pinpoint which David Jenkinson you are referring to.
E. L. Moore, or Everett Lee Moore, was an influential American mathematician and educator known primarily for his work in topology, particularly in the area of general topology and the theory of compact spaces.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
