Web programming, often referred to as web development, encompasses the process of creating applications and services that run on the World Wide Web. It involves several components, including client-side and server-side programming, as well as database management. Here's a breakdown of the main elements: ### 1. **Client-Side Development:** - **Languages:** Typically involves HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JavaScript.
"The Fool on the Hill" is a ballet choreographed by the renowned British choreographer and dancer, Sir Kenneth MacMillan. The ballet premiered in 1969 and is set to music by the composer and musician, The Beatles. Specifically, it is inspired by the song "The Fool on the Hill," written by Paul McCartney and John Lennon.
The Crystallographic Restriction Theorem is a concept in the field of crystallography and solid state physics that describes certain symmetries in crystalline materials. It states that the symmetry operations of a crystal, such as rotations, translations, and reflections, impose restrictions on the types of point groups that can be realized in three-dimensional space. More specifically, the theorem states that the only symmetry operations allowed for a crystal lattice in three dimensions must be compatible with the periodicity of the lattice.
"Soft Kitty" is a song that gained popularity from the television show "The Big Bang Theory." It is often sung by the character Sheldon Cooper, portrayed by Jim Parsons, as a form of comfort when he is feeling unwell or distressed. The lyrics describe a soft, warm kitten and evoke feelings of coziness and care. The song has become an iconic part of the show's culture and is frequently referenced by fans. The simple melody and heartwarming lyrics contribute to its charm and appeal.
Fuchs' theorem is a result in the field of complex analysis, particularly in the study of ordinary differential equations with singularities. The theorem provides conditions under which a linear ordinary differential equation with an irregular singular point can be solved using power series methods. Specifically, Fuchs' theorem states that if a linear differential equation has only regular singular points, then around each regular singular point, there exist solutions that can be expressed as a Frobenius series.
Abel's binomial theorem is a generalization of the binomial theorem that is used in the context of power series and infinite sums. It provides a way to represent the sums of powers in a more general setting than the classic binomial theorem, which only applies to finite sums.
Komlós' theorem, also known as Komlós' conjecture, is a result in combinatorial mathematics, specifically in the field of graph theory. The theorem deals with the concept of almost perfect matchings in large graphs.
The Denjoy–Young–Saks theorem is a result in measure theory concerning the decomposition of the Lebesgue measurable sets. It is named after mathematicians Arne Magnus Denjoy, John Willard Young, and Aleksandr Yakovlevich Saks, who contributed to the development of this area of mathematics.
Fenchel's duality theorem is a fundamental result in convex analysis and optimization, which establishes a relationship between a convex optimization problem and its dual problem. Specifically, it provides conditions under which the solution of a primal convex optimization problem can be found by solving its dual.
The Malgrange preparation theorem is a result in complex analysis and algebraic geometry that is concerned with the behavior of analytic functions and their singularities. It provides a way to analyze and decompose certain classes of analytic functions near isolated singular points.
The Goldbach–Euler theorem is a result in number theory that relates to the representation of even integers as sums of prime numbers. More specifically, it builds on the ideas of the original Goldbach conjecture. While the conjecture itself states that every even integer greater than 2 can be expressed as the sum of two prime numbers, the Goldbach–Euler theorem provides a more generalized framework.
Trudinger's theorem, often discussed in the context of variational calculus and partial differential equations, refers to a result concerning minimization problems for integral functionals that involve "non-standard" growth conditions. Specifically, it addresses the existence of solutions to certain minimization problems that contain terms with exponential growth.
The Peano existence theorem, often referred to in the context of ordinary differential equations (ODEs), is a fundamental result that provides conditions under which solutions to certain initial value problems exist.
The Remez inequality is a result in approximation theory that provides a bound on the deviation of a continuous function from its best approximation by a polynomial. Specifically, it relates the norm of a polynomial approximation to the maximum deviation of the approximated function over a given interval.
The Hyperbolization Theorem is a result in the field of topology and geometric group theory, specifically concerning the characteristics of 3-manifolds. It states that any compact, orientable 3-manifold that contains a certain type of submanifold (specifically, a “reducible” submanifold or one that can be "hyperbolized") can be decomposed into pieces that exhibit hyperbolic geometry.
Geometric inequalities are mathematical statements that establish relationships between different geometric quantities, such as lengths, areas, angles, and volumes. These inequalities often provide useful bounds or constraints on these quantities and can be applied in various fields, including geometry, optimization, and analysis. Some common types of geometric inequalities include: 1. **Triangle Inequalities**: In any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Theorems about curves cover a vast range of topics in mathematics, particularly in geometry, calculus, and topology. Here are some key theorems and concepts associated with curves: 1. **Fermat's Last Theorem for Curves**: While Fermat's Last Theorem primarily concerns integers, there are generalizations and discussions about elliptic curves in number theory that relate deeply to the properties of curves.
Anderson's theorem, formulated by P.W. Anderson in the context of condensed matter physics, primarily relates to the behavior of disordered systems, particularly in the study of superconductivity and localization effects. The theorem is often associated with the concept of Anderson localization, which describes how wavefunctions (such as those of electrons) can become localized in a disordered medium and thus inhibit electrical conductivity.
The Euclid–Euler theorem, also known as Euler's theorem in the context of number theory, relates to the area of geometry and can be specifically described in two ways.
The Spherical Law of Cosines is a fundamental theorem in spherical geometry, which deals with the relationships between the angles and sides of spherical triangles (triangles drawn on the surface of a sphere). Specifically, it is used to relate the lengths of the sides of a spherical triangle and the cosine of one of its angles.

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.
