Max Born (1882–1970) was a distinguished physicist and mathematician known for his foundational contributions to quantum mechanics and crystallography. He was awarded the Nobel Prize in Physics in 1954 for his work in the statistical interpretation of quantum mechanics. Below is a bibliography highlighting some of his notable works: ### Books 1. **"Principles of Optics"** (with Emil Wolf) - A foundational text in optical theory, discussing both classical and modern optics.
The *Proceedings of the Combustion Institute* is a scholarly journal that publishes research articles and papers related to the field of combustion science and engineering. It serves as a platform for researchers, engineers, and academics to disseminate their findings and advancements in combustion research. The journal covers a wide range of topics, including but not limited to combustion physics and chemistry, combustion processes, emissions, fuel properties, engine performance, and experimental and computational studies related to combustion.
A biogeochemical cycle is a natural process that recycles nutrients in various forms from the non-living environment to living organisms and back again. This cycle involves the transformation and movement of elements and compounds between biological (biotic) and geological (abiotic) components of the Earth.
Biological membranes, also known as biomembranes, are essential structures that form the outer and inner boundaries of cells and organelles. They serve as critical components in maintaining the integrity and functionality of cells. Here are some key features and functions of biological membranes: ### Structure 1.
Biotron, located in Wisconsin, is a research facility that specializes in controlled environment research. It is part of the University of Wisconsin-Madison and is primarily focused on plant and environmental sciences. The facility is designed to simulate various environmental conditions, allowing researchers to study plant responses to factors such as temperature, light, humidity, and atmospheric composition.
Geodetic surveys are a type of surveying that focuses on measuring large areas of the Earth's surface, taking into account the curvature of the Earth. Unlike traditional land surveys, which often deal with small plots of land, geodetic surveys are designed to gather precise measurements over extensive distances. Key aspects of geodetic surveys include: 1. **Earth's Shape**: The Earth is not a perfect sphere; its shape is more accurately described as an oblate spheroid.
Birmabright is a type of aluminum alloy, specifically known for its use in the manufacturing of various components, including railway vehicles and other structural applications. The alloy is characterized by its combination of strength, lightweight nature, and resistance to corrosion. It is often used in industries requiring durable and lightweight materials, such as transportation, automotive, and aerospace.
Black hole greybody factors are a concept in theoretical physics that describe how the radiation emitted by a black hole is modified due to the black hole's properties and the surrounding spacetime geometry. When a black hole emits radiation, such as Hawking radiation, the efficiency of this emission can vary depending on the wavelength of the emitted radiation and the specific characteristics of the black hole.
The Bocca della Verità, or "Mouth of Truth," is a famous ancient marble mask located in the portico of the Santa Maria in Cosmedin church in Rome, Italy. It is believed to date back to the 1st century AD and is often associated with Roman mythology and folklore. The mask is traditionally thought to represent the face of a river god, and it has become a popular symbol in Roman culture.
A bolted joint is a type of mechanical fastener connection that uses bolts to hold two or more parts together. Bolted joints are widely used in various engineering applications, such as in buildings, machinery, bridges, and automotive structures, due to their strength, reliability, ease of assembly, and disassembly. ### Key Components of a Bolted Joint: 1. **Bolt**: A cylindrical rod with a head on one end and a threaded shaft.
The projectively extended real line is a mathematical construction that extends the standard real numbers by adding two points at infinity. This extension is particularly useful in various areas of analysis and projective geometry. In more detail, the projectively extended real line is denoted by \(\mathbb{R} \cup \{ -\infty, +\infty \}\).
Geometric algebra is a mathematical framework that extends traditional algebra by incorporating geometric concepts. It is a unifying language for describing geometric transformations and relationships, merging algebraic and geometric perspectives. Here are some key aspects of geometric algebra: 1. **Multivectors**: In geometric algebra, quantities such as points, lines, planes, and volumes are represented as multivectors.
Boris Chichkov is a notable figure primarily recognized for his contributions to the field of scientific research and technology. He is particularly known for his work in laser technologies and biomedical applications, including the development of techniques related to laser microfabrication and materials science. Chichkov's research has implications in various areas such as optics, manufacturing, and medical devices.
The Born-Oppenheimer approximation is a fundamental concept in molecular quantum mechanics that simplifies the study of molecular systems by decoupling the motion of nuclei and electrons. The core idea is based on the significant difference in mass between nuclei (which are heavy) and electrons (which are much lighter). This mass difference leads to different time scales for their motions.
Bram van Heel is a professional in the field of contemporary art, particularly known for his work in curation and art criticism. He has been associated with various exhibitions and projects that explore themes in contemporary art.

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
