A worm-like chain (WLC) is a theoretical model used in polymer physics and biophysics to describe the conformational properties of long, flexible polymers. The model helps in understanding the behavior of macromolecules such as DNA, proteins, and synthetic polymers. Key characteristics of the worm-like chain model include: 1. **Continuous Chain**: The worm-like chain is often represented as a continuous chain of tangent segments, where each segment maintains a certain angle with respect to its neighbors.

An Enriques surface is a specific type of algebraic surface that has several interesting geometric and topological properties. They are named after the Italian mathematician Federigo Enriques, who studied these types of surfaces in the early 20th century. Here are some key characteristics and properties of Enriques surfaces: 1. **Classification**: Enriques surfaces belong to a broader classification of surfaces in algebraic geometry, which includes other types like K3 surfaces, rational surfaces, and so on.

Not everything is perfect.

One big problem of many big open source projects is that they are contributed to by separate selfish organizations, that have private information. Then what happens is that:

Another common difficulty is that open source maintainers may simply not care enough about their own project (maybe they did in the past but lost interest) to review external patches by people they don't know.

This is understandable: a new patch, is a new risk of things breaking.

Therefore, if you ever submit patches and they get ignore, don't be too sad. It just comes down to a question of maintenance cost, and means that you will waste some extra time on the next rebase. You just have to decide your goals and be cold about it:

Writing documentation in an open source project in which you don't have immediate push rights is another major pain due to code reviews. Code code reviews tend to be much less subjective, because if you do something wrong, stuff crashes, runs slower, or you need more lines of code to reach the same goal. There are tradeoffs, but in a limited number. Documentation code reviews on the other hand, are an open invitation to infinite bike-shedding, since you can't "run" documentation through a standardized brain model. Much better is for one good documenter person to just make one cohesive Stack Overflow post, and ping others with more knowledge to review details or add any missing pieces :-)

MISRA C (Motor Industry Software Reliability Association C) is a set of software development guidelines and coding standards specifically designed for the C programming language to promote safety, portability, and reliability in software used in automotive and other critical systems. The guidelines were established in 1998 and have undergone several revisions since then, with the latest version being MISRA C:2012.

"Rigour" generally refers to strictness, precision, and thoroughness in processes, thinking, analysis, or application. The term is often used in various contexts, including: 1. **Education**: Refers to the depth and quality of learning experiences. A rigorous educational program challenges students with demanding coursework, promotes critical thinking, and requires substantial effort and mastery of subjects.

"Atomic Spy" is a historical non-fiction book written by the journalist and author Gina McKinnon. The book details the life of Klaus Fuchs, a German-born physicist who became a key figure in the development of the atomic bomb during World War II. Fuchs was also a spy for the Soviet Union, passing critical information about nuclear weapons to the Soviets, which had significant implications during the Cold War.

From the abstract:Ciro Santilli couldn't agree more... notably students must have a flexible choice of what to learn.

"The Big Bang" is a book by Indian author and historian of science, Dr. A. P. J. Abdul Kalam. The book explores not only the scientific concepts surrounding the Big Bang theory but also delves into the philosophical, cultural, and historical aspects of how humanity has come to understand the universe's origin. In the narrative, there's typically a mix of scientific explanation alongside personal reflections and insights from the author.

"Einstein's Unfinished Symphony" is a term often used to refer to the ongoing quest to unify the fundamental forces of nature in physics. It metaphorically draws upon the image of an unfinished musical composition to highlight the incomplete nature of our understanding of the universe, particularly in the context of theoretical physics.

Howard Wilson is a physicist known for his contributions to research in areas such as condensed matter physics and materials science. His work often involves the study of electronic materials and their properties. However, specific details about his research, achievements, or professional background may not be widely known or documented in popular literature.

There are apparently two methods:

"Physics and Beyond" is a book written by the renowned physicist and Nobel laureate, Wolfgang Pauli. Published posthumously in 1994, the book is a collection of essays and lectures that explore not only the fundamental principles of physics but also the philosophical implications and broader contexts of those principles.

Madge Networks, founded in the early 1990s, was a technology company known for its networking solutions, particularly in the field of local area networks (LANs) and wide area networks (WANs). The company specialized in providing products and services related to connectivity and network infrastructure, including bridges, routers, and network management software. One of Madge Networks' notable contributions was its work with token ring technology, which was an important networking standard before the widespread adoption of Ethernet.

The traffic is designed for cars, which makes many red stops for bicycles completely stupid.

In a bicycle you just have too much more control and awareness than in a car, so if the way is completely clear, you should be allowed to stop, look if the way is clear, and then run reds.

Of course, this does increase the chances of hitting pedestrians a little bit. But the risk change feels so little that it would be worth it. Studies quoted by Wikipedia corroborate. It just feels extremely unintuitive to make cyclists stop in certain places when the street is clear.

"Priest of Nature" is a term that can refer to a few different concepts, depending on the context. In gaming, specifically in the context of tabletop role-playing games like Dungeons & Dragons or similar settings, it may refer to a character class or archetype that specializes in nature-based magic and abilities.

The only thing that matters is that students aim towards the goals described at explain how to make money with the lesson.

Any "homework for which the student cannot use existing resources available online" is a waste of time.

The ideal way to go about it is to reach some intermediate milestone, and then document it. You don't have to do the hole thing! Just go until your patience with it runs out. But while you are doing it, go as deep and wide as you possibly can, without mercy.

This is actually how Ciro Santilli learns new subjects he is curious about, even as an adult! Some examples:
