The ultrarelativistic limit refers to the behavior of particles as their velocities approach the speed of light, \(c\). In this limit, the effects of special relativity become especially pronounced because the kinetic energy of the particles becomes significantly greater than their rest mass energy.
The Chebyshev–Markov–Stieltjes inequalities refer to a set of results in probability theory and analysis that provide estimates for the probabilities of deviations of random variables from their expected values. These inequalities are generalizations of the well-known Chebyshev inequality and are closely related to concepts from measure theory and Stieltjes integrals.
Holmgren's uniqueness theorem is a result in the theory of partial differential equations (PDEs), particularly concerning elliptic equations. It addresses the uniqueness of solutions to certain boundary value problems.
Jensen's inequality is a fundamental result in convex analysis and probability theory that relates to convex functions.
The Picard–Lindelöf theorem, also known as the Picard existence theorem or the Picard-Lindelöf theorem, is a fundamental result in the theory of ordinary differential equations (ODEs). It provides conditions under which a first-order ordinary differential equation has a unique solution in a specified interval.
Sard's theorem is a result in differential topology that pertains to the behavior of smooth functions between manifolds. Specifically, it addresses the notion of the image of a smooth function and the measure of its critical values.
The Fréchet inequalities are a set of mathematical inequalities related to the concept of distance in metric spaces and the properties of certain functions. They are particularly significant in the context of probability and statistics, especially in relation to the Fréchet distance, which is used to measure the similarity between two probability distributions. In probability theory, the Fréchet inequalities express relationships between various statistical metrics, often involving expectations and norms.
Carl Gustav Jacob Jacobi (1804-1851) was a prominent German mathematician known for his significant contributions to various areas of mathematics, particularly in the fields of algebra, analysis, and mathematical physics. He is best known for his work on elliptic functions, theory of determinants, and the theory of dynamic systems. Jacobi was one of the first mathematicians to systematically study elliptic functions and made important advances in the development of elliptic integrals.
The Fermat–Catalan conjecture is a conjecture in number theory that deals with a specific type of equation related to powers of integers.
The Thue equation is a type of Diophantine equation, which is a polynomial equation that seeks integer solutions. Specifically, a Thue equation has the general form: \[ f(x, y) = h \] where \(f(x, y)\) is a homogeneous polynomial in two variables with integer coefficients, and \(h\) is an integer.
It seems like there might be a typographical error in your question or that "Albert A. Mullin" may not be a widely recognized person, concept, or entity based on the information available up to October 2023. There is a possibility you're referring to a different name or topic.
Arjen Lenstra is a Dutch mathematician and computer scientist known for his work in the areas of number theory, cryptography, and the mathematics of computation. He is particularly notable for his contributions to the field of cryptanalysis, which involves the study of methods for breaking cryptographic systems. Lenstra has worked on various aspects of mathematical algorithms and has been involved in significant advancements related to public key cryptography and integer factorization.
Audrey Terras is a mathematician known for her contributions to the fields of number theory and algebraic geometry. She has made significant contributions to the study of modular forms and has worked on topics related to the theory of automorphic forms, as well as mathematical research involving complex analysis and topology. Terras is also recognized for her work in mathematics education and outreach.
Mean sojourn time refers to the average amount of time that a system, individual, or process spends in a particular state before transitioning to another state. It is a concept commonly used in various fields such as queuing theory, operations research, and systems analysis. In the context of queuing systems, for instance, the mean sojourn time can represent the average time a customer spends in the system, which includes the time waiting in line as well as the time being served.
This paper appears to calculate the Schrödinger equation solution for the hydrogen atom.
TODO is this the original paper on the Schrödinger equation?
Published on Annalen der Physik in 1926.
Open access in German at: onlinelibrary.wiley.com/doi/10.1002/andp.19263840404 which gives volume 384, Issue 4, Pages 361-376. Kudos to Wiley for that. E.g. Nature did not have similar policies as of 2023.
This paper may have fallen into the public domain in the US in 2022! On the Internet Archive we can see scans of the journal that contains it at: ia903403.us.archive.org/29/items/sim_annalen-der-physik_1926_79_contents/sim_annalen-der-physik_1926_79_contents.pdf. Ciro Santilli extracted just the paper to: commons.wikimedia.org/w/index.php?title=File%3AQuantisierung_als_Eigenwertproblem.pdf. It is not as well processed as the Wiley one, but it is of 100% guaranteed clean public domain provenance! TODO: hmmm, it may be public domain in the USA but not Germany, where 70 years after author deaths rules, and Schrodinger died in 1961, so it may be up to 2031 in that country... messy stuff. There's also the question of wether copyright is was tranferred to AdP at publication or not.

Ciro Santilli's admiration for Dyson goes beyond his "unify all the things approach", which Ciro loves, but also extends to the way he talks and the things he says. Dyson is one of Ciro's favorite physicist.
Besides this, he was also very idealistic compassionate, and supported a peaceful resolution until World War II with United Kingdom was basically inevitable. Note that this was a strategic mistake.
Dyson is "hawk nosed" as mentioned in Genius: Richard Feynman and Modern Physics by James Gleick (1994) chapter "Dyson". But he wasn't when he was young, see e.g. i2.wp.com/www.brainpickings.org/wp-content/uploads/2016/03/freemandyson_child-1.jpg?resize=768%2C1064&ssl=1 It seems that his nose just never stopped growing after puberty.
He also has some fun stories, like him practicing night climbing while at Cambridge University, and having walked from Cambridge to London (~86km!) in a day with his wheelchair bound friend.
Ciro Santilli feels that the label child prodigy applies even more so to him than to Feynman and Julian Schwinger.

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
