His contributions have been significant, particularly regarding the understanding of Earth's shape and its gravitational anomalies.
Atira asteroids, also known as Apohele asteroids, are a group of asteroids that have orbits entirely within the orbit of Earth. This means that their maximum distance from the Sun is less than that of the Earth's average distance from the Sun, which is about 1 astronomical unit (AU). Atira asteroids are named after the first discovered member of this group, 163693 Atira, which was identified in 2003.
The "List of named minor planets: X" refers to a compilation of minor planets (or asteroids) that have been designated with names that start with the letter "X." Minor planets are small celestial bodies that orbit the Sun, and many of them are named after various figures from mythology, history, literature, and other cultural references.
The List of minor planets from 125001 to 126000 is a compilation of numbered asteroids and minor planets that have been cataloged by the International Astronomical Union (IAU). Each minor planet is assigned a unique number and often has a name that is either descriptive or honors a person, place, or cultural theme.
Jupiter LXVII, also known as S/2011 J 1, is a small natural satellite of Jupiter. It is one of several moons that orbit the gas giant and was discovered in 2011. Like many of Jupiter's smaller moons, it is irregularly shaped and belongs to a group of outer moons that are thought to be captured asteroids or debris. Jupiter LXVII has a diameter of approximately 2 kilometers (about 1.
S/2022 J 2 is a designation for a small moon of Jupiter. It was discovered in 2022 and is part of the group's moons that also includes several other small, irregularly shaped satellites. The designation typically follows the format where "S/" refers to "satellite," followed by the year of discovery and the letter "J" for Jupiter. The number "2" indicates that it is the second moon discovered in that year for Jupiter.
The list of minor planets numbered from 543001 to 544000 includes a range of asteroids and other small celestial bodies that have been identified and cataloged in the Minor Planet Center's database. Each object is assigned a unique number and may also have a provisional designation or a name. This segment of minor planets typically consists of discoveries that have been made primarily in the 21st century, as the numbering system continues sequentially.
Albiorix is one of the moons of Saturn. It was discovered in 2000 and is classified as a small, irregular satellite. Albiorix is part of the Inuit group of moons, which are a collection of moons that share similar orbits and characteristics. Albiorix is approximately 38 kilometers (about 24 miles) in diameter and has a somewhat elongated shape, typical of many irregularly shaped moons.

SOGIN (Società Gestione Impianti Nucleari) is an Italian public company responsible for the management and decommissioning of nuclear facilities and the handling of radioactive waste in Italy. Established in 1999, SOGIN's primary mission is to ensure the safe and secure dismantling of nuclear power plants and the proper management of radioactive materials that result from this process. The company also works on waste management and disposal strategies, ensuring compliance with national and international safety standards.
United Nations Security Council Resolution 1874, adopted on June 12, 2009, addresses the issue of North Korea's nuclear weapons program. This resolution was enacted in response to North Korea's nuclear test conducted on May 25, 2009, which was widely condemned by the international community.
The Landau Institute for Theoretical Physics is a prominent research institute located in Chernogolovka, Russia. It was founded in 1965 and is named after the renowned physicist Lev Davidovich Landau, who won the Nobel Prize in Physics in 1962 for his work on condensed matter physics. The institute focuses on a wide range of topics in theoretical physics, including areas such as condensed matter physics, statistical mechanics, quantum field theory, and many-body physics.
GE Infrastructure, a division of General Electric (GE), was focused on providing a broad range of services and technologies for critical infrastructure in various sectors. Although the precise name "GE Infrastructure" may not be used as prominently in recent times, historically, the division encompassed several key areas such as: 1. **Energy**: This involved products and services related to power generation, including gas turbines, wind turbines, and other renewable energy technologies.
The MGM-5 Corporal was an early U.S. Army surface-to-surface missile developed in the late 1940s and early 1950s. It represented one of the first operational ballistic missiles and played a significant role in the development of guided missile technology during the Cold War era.
Sputnik 1 was the first artificial satellite to be launched into space. It was a Soviet spacecraft that was successfully launched on October 4, 1957. The satellite was a spherical object, approximately 58 centimeters (about 23 inches) in diameter, and weighed around 83.6 kilograms (about 184 pounds). Sputnik 1's launch marked a significant milestone in the Space Race between the United States and the Soviet Union.
In Physics, in order to test a theory, you must be able to extract a number from it.
It does not matter how, if it is exact, or numerical, or a message from God: a number has to come out of the formulas in the end, and you have to compare it with the experimental data.
Many theoretical physicists seem to forget this in their lectures, see also: Section "How to teach and learn physics".
Quantum field theory by Ciro Santilli 37 Updated 2025-07-16
Theoretical framework on which quantum field theories are based, theories based on framework include:so basically the entire Standard Model
The basic idea is that there is a field for each particle particle type.
And then those fields interact with some Lagrangian.
One way to look at QFT is to split it into two parts:
Then interwined with those two is the part "OK, how to solve the equations, if they are solvable at all", which is an open problem: Yang-Mills existence and mass gap.
There appear to be two main equivalent formulations of quantum field theory:

Quantum Field Theory visualized by ScienceClic English (2020)
Source. Gives one piece of possibly OK intuition: quantum theories kind of model all possible evolutions of the system at the same time, but with different probabilities. QFT is no different in that aspect.

Quantum Field Theory: What is a particle? by Physics Explained (2021)
Source. Gives some high level analogies between high level principles of non-relativistic quantum mechanics and special relativity in to suggest that there is a minimum quanta of a relativistic quantum field.

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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
