"Het Luitboek van Thysius" (translated as "The Lute Book of Thysius") is a collection of lute music that is attributed to the 16th-century music theorist and lutenist, Michael Thysius. The manuscript contains a variety of works, including dances, arrangements of songs, and original lute compositions, reflecting the musical style of the Renaissance period.
Confidential incident reporting refers to a process or system that allows individuals, often within an organization, to report incidents, concerns, or violations without revealing their identity. This can be particularly important in settings where employees may fear retaliation, stigma, or disciplinary actions for speaking up about issues such as safety violations, harassment, fraud, or other unethical behavior.
The quasi-geostrophic equations are a set of mathematical equations used to describe the dynamics of large-scale atmospheric and oceanic flows in the presence of rotation and stratification. These equations are an approximation of the full Navier-Stokes equations, focusing on flows that are geostrophic, meaning that the Coriolis force (due to the Earth's rotation) balances the pressure gradient force.
The "degree of anonymity" generally refers to the extent to which an individual's identity is concealed or protected while engaging in activities, particularly in online environments. It can be understood in several contexts: 1. **Online Activities**: In the digital space, the degree of anonymity can vary based on the methods and tools used for online interactions. Some platforms may allow users to operate under pseudonyms, while others may require real identities. Technologies like VPNs, Tor, and encryption can enhance anonymity.
Like the rest of the Standard Model Lagrangian, this can be split into two parts:
Video 1.
Deriving the qED Lagrangian by Dietterich Labs (2018)
Source.
As mentioned at the start of the video, he starts with the Dirac equation Lagrangian derived in a previous video. It has nothing to do with electromagnetism specifically.
He notes that that Dirac Lagrangian, besides being globally Lorentz invariant, it also also has a global invariance.
However, it does not have a local invariance if the transformation depends on the point in spacetime.
He doesn't mention it, but I think this is highly desirable, because in general local symmetries of the Lagrangian imply conserved currents, and in this case we want conservation of charges.
To fix that, he adds an extra gauge field (a field of matrices) to the regular derivative, and the resulting derivative has a fancy name: the covariant derivative.
Then finally he notes that this gauge field he had to add has to transform exactly like the electromagnetic four-potential!
So he uses that as the gauge, and also adds in the Maxwell Lagrangian in the same go. It is kind of a guess, but it is a natural guess, and it turns out to be correct.
TODO find a concrete numerical example of doing calculus on a differentiable manifold and visualizing it. Likely start with a boring circle. That would be sweet...
It gets the job done, but cannot make a large codebase DRY without insanity.
As of 2020, C is like Latin, and we are in the Middle Ages, where it has become a lingua franca.
It is interesting to note how late C appeared: 1972, compared e.g. to Fortran which is from 1957. This is basically because C was a "systems programming language", i.e. with focus on pointer manipulation, and because early computers were so weak, there was no operating system or many software layers in the early days. Fortran however was a numerical language, and it ran directly on bare metal, an application that existed before systems programming.
Examples under c.
Itai Benjamini is likely a reference to a person associated with a specific field or context, but without additional context, it is difficult to provide precise information. Several individuals share the name, and they may be known for different contributions in areas such as academia, business, or other domains.
The Hollerith Electronic Computer, often referred to as the "Hollerith machine," usually refers to a type of early computer system associated with the work of Herman Hollerith. Hollerith was an American inventor who developed a mechanical system for processing data using punched cards, which he introduced in the late 19th century. His technology was pivotal in the development of data processing for the U.S. Census and laid the groundwork for the future of computing.
Hungarian biophysicists refer to scientists from Hungary who specialize in biophysics, which is an interdisciplinary field combining biology and physics. Biophysicists study biological phenomena using the principles and methods of physics, often focusing on the molecular and cellular levels to understand the physical mechanisms that underlie biological processes. Hungary has a rich history in the sciences, including notable contributions to biophysics.
"Hypercolour" is a song by the band **Sick Puppies**, released in 2023. It showcases the band's signature blend of alternative rock and post-grunge sounds. The song features themes of personal transformation and the contrast between darkness and light, reflecting a journey of self-discovery and empowerment. The band's energetic instrumentation and catchy melodies complement the introspective lyrics, making it resonate with a wide audience.
Isle of the Dead is a small island located in Port Arthur, Tasmania, Australia. It is historically significant as it was used as a cemetery for the convicts and staff of the Port Arthur penal settlement during the 19th century. The island is approximately 1.5 hectares in size and contains around 500 graves.
Idiopathic short stature (ISS) refers to a condition in which a child has a height significantly below the average for their age and sex, but no identifiable medical cause can be determined. In other words, despite extensive evaluations, including growth hormone levels, genetic tests, and assessments for chronic illnesses, a reason for the short stature cannot be found.
The IEEE Transactions on Electromagnetic Compatibility (EMC) is a peer-reviewed scientific journal published by the Institute of Electrical and Electronics Engineers (IEEE). This journal specializes in research related to electromagnetic compatibility, which is a field that addresses the interaction between electronic devices, systems, and their electromagnetic environment.
The Independent Lubricant Manufacturers Association (ILMA) is an industry trade organization that represents the interests of independent lubricant manufacturers in the United States and elsewhere. Founded in 1948, ILMA provides a platform for its members to network, share knowledge, and advocate for policies that support the lubricant manufacturing industry. ILMA's members include companies that produce, blend, and package lubricants and related products, as well as suppliers and service providers to the industry.

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
