Walter Dornberger (1895–1980) was a German engineer and military officer, best known for his role in the development of the V-2 rocket during World War II. He was a prominent figure in the German rocket program and worked under the guidance of Wernher von Braun at the Peenemünde Army Research Center. Dornberger's work contributed significantly to the advancement of rocket technology, and after the war, he was captured by Allied forces.
Color blind glasses are specially designed eyewear aimed at helping individuals with color vision deficiencies (color blindness) to perceive colors more accurately. These glasses use specific filters to enhance the contrast between colors, making it easier for those with color blindness to distinguish between different hues that may appear similar. There are several types of color blindness, with the most common being red-green color blindness.
B. S. Madhava Rao is a prominent figure known for his contributions to education, particularly in the field of management and engineering education in India. He has played significant roles in various educational institutions and has been involved in shaping policies and programs that enhance higher education standards. If you meant something specific regarding him or if there is a different context or aspect of B. S.
A bubble raft, also known as a bubble raft experiment or bubble raft model, is a type of scientific experiment used primarily in physics and materials science to study the properties of materials, particularly in the context of bubble formation and dynamics. In the context of physics, a bubble raft can refer to a two-dimensional system where bubbles (or air pockets) are trapped in a thin layer of liquid or gel.
The Bulk Richardson number (often denoted as \( \text{Ri}_B \)) is a dimensionless parameter used in meteorology and oceanography to assess the stability of a fluid layer, particularly in relation to the vertical mixing of buoyancy-driven flows, such as those found in the atmosphere or ocean. It compares the potential energy associated with buoyancy to the kinetic energy associated with vertical shear.
The Bulletin of the American Mathematical Society (AMS) is a mathematical journal published by the American Mathematical Society. It serves as a platform for research announcements, surveys, and expository articles that provide insights into various areas of mathematics. The bulletin typically includes brief reports on significant advancements in mathematics, as well as reviews of mathematical literature. The publication aims to communicate important developments in the field to a broad mathematical audience, making high-level research accessible to mathematicians who may not specialize in certain areas.
Burchard de Volder refers to a prominent figure in the field of astronomy and mathematics during the 17th century. He was a Dutch mathematician and astronomer associated with the University of Amsterdam, where he made contributions to the scientific community, including work on optics and the study of celestial bodies.
The Burlesque Hall of Fame (BHoF) is a museum located in Las Vegas, Nevada, dedicated to preserving and celebrating the art and history of burlesque performance. Established in 2005, the Hall of Fame features exhibits that showcase the evolution of burlesque from the late 19th century to the present day, highlighting its cultural significance and impact on entertainment.
Quadratic growth refers to a type of growth characterized by a quadratic function, which is a polynomial function of degree two. A common form of a quadratic function is given by: \[ f(x) = ax^2 + bx + c \] where: - \(a\), \(b\), and \(c\) are constants, and \(a \neq 0\). - The variable \(x\) is the input.
Transseries are a mathematical concept that generalizes the notion of series and can be used to analyze functions or solutions to equations that have a certain type of asymptotic behavior. They extend the traditional power series by allowing for non-integer powers and infinitely many terms, accommodating a broader range of asymptotic expansions. A transseries can be thought of as an expression made up of multiple components, combining both exponential-type and polynomial-type growths.
Calculus of variations is a field of mathematical analysis that deals with optimizing functionals, which are mappings from a set of functions to the real numbers. In simpler terms, it involves finding a function that minimizes or maximizes a specific quantity defined as an integral (or sometimes an infinite series) of a function and its derivatives. ### Key Concepts: 1. **Functional**: A functional is typically an integral that represents some physical quantity, such as energy or action.
In number theory, "squares" refers to the squares of whole numbers. A square of a number is the result of multiplying that number by itself. For example, the square of 2 (written as \(2^2\)) is \(2 \times 2 = 4\), and the square of 3 (written as \(3^2\)) is \(3 \times 3 = 9\).

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
