The Weinberg angle, also known as the weak mixing angle or the electroweak mixing angle, is a fundamental parameter in the electroweak theory, a critical component of the Standard Model of particle physics. It quantifies the mixing between the electromagnetic force and the weak nuclear force, which are unified at high energies. Specifically, the Weinberg angle (\(\theta_W\)) determines the relationship between the electric charge and the weak isospin of particles.
The upper half-plane generally refers to a specific region in the complex plane. In complex analysis, it is defined as the set of all complex numbers whose imaginary part is positive.
The number 67 is an integer that comes after 66 and before 68. It is an odd number and is a prime number, meaning it has no positive divisors other than 1 and itself.

Vectorette PCR is a molecular biology technique used to amplify specific DNA sequences from complex mixtures. It's particularly useful for isolating and amplifying sequences from genomic DNA when working with certain types of samples, such as those where the target sequence is flanked by unknown or non-specific DNA. The technique involves the use of a "vectorette" — a short, known DNA sequence that is ligated to the ends of the target DNA fragments.
Vector radiative transfer refers to the study of how electromagnetic radiation, particularly light, interacts with matter in a medium where the properties of the radiation can be described by vectors. This is an extension of the classical radiative transfer theory that typically considers scalar radiative transfer, which is simpler but less accurate in certain situations. In vector radiative transfer, the polarization state of light is taken into account, which is essential when dealing with scattering processes involving particles, atmospheric optics, and remote sensing applications.
A "friendly number" typically refers to a number that is part of a pair or set of numbers with a mutual relationship, where two numbers share a specific mathematical characteristic. The term is most commonly associated with the concept of "friendly pairs" or "friendly numbers" in the context of number theory, particularly in relation to amicable numbers.
The Vehicle Routing Problem (VRP) is a combinatorial optimization problem that aims to determine the most efficient routes for a fleet of vehicles to deliver goods to a set of customers. It is a fundamental problem in logistics and transportation and has applications in various industries, including delivery services, food distribution, and waste collection. The primary objective of the VRP is to minimize certain costs, such as total distance traveled, time taken, or operational expenses while ensuring that all customer demands are met.
Pitch class space is a concept in music theory that refers to the organization of pitch classes into a conceptual space where notes are treated as equivalent if they are related by octave. In this context, a pitch class is a set of all pitches that are a whole number of octaves apart. For example, the pitch classes C, C#, D, D#, etc., are all represented in their respective "space.
"Werk 80 II" is an album by the German heavy metal band Atrocity, released in 1999. It is a continuation of their earlier album "Werk 80," which consisted of covers of various songs from the 1980s, reinterpreted in the band's signature style. "Werk 80 II" follows this concept, featuring new renditions of popular tracks from that era, blending metal and gothic elements with the original songs.
Video game platform emulators are software applications or hardware devices that mimic the functionality of a specific video game console or computer system, allowing users to play games designed for that platform on different hardware. Emulators replicate the original system's hardware architecture, enabling games to run on various platforms like PCs, smartphones, or other consoles.
PKCS #7, which stands for "Public Key Cryptography Standards" #7, is a standard for cryptographically protected messages. It specifies a syntax for data that may be encrypted, signed, or both. It is commonly used in various cryptographic protocols and applications, such as email encryption (e.g., S/MIME) and document signing.
A planar surface is a flat, two-dimensional surface that extends infinitely in all directions within its plane. In mathematics and geometry, a plane is defined by a flat surface that is characterized by two dimensions—length and width—while having no depth. Planar surfaces can be represented in various ways, such as through geometric shapes (like rectangles or triangles), equations (such as the equation of a plane in 3D space), or in computer graphics as polygons.
The 106th meridian east is a line of longitude that is situated 106 degrees east of the Prime Meridian, which runs through Greenwich, England.

Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.
