"Numbers: The Universal Language" is a concept that explores the idea that numbers and mathematics serve as a universal means of communication across different cultures and languages. This expression often reflects the notion that mathematical principles and numerical concepts can be understood and applied globally, transcending linguistic barriers. The topic can be explored in various contexts, including: 1. **Mathematical Principles**: Fundamental mathematical ideas, such as counting, shapes, and arithmetic, are understood universally, regardless of cultural differences.
"The Mathematical Experience" is a book co-authored by Philip J. Davis and Reuben Hersh, first published in 1981. The work explores the nature and philosophy of mathematics, emphasizing the human and experiential aspects of mathematical thinking rather than focusing solely on technical details or formalism. The book is notable for its engaging and accessible writing style, aiming to appeal to both mathematical professionals and a broader audience.
"A Mathematician's Lament" is an influential essay written by Paul Lockhart in 2002. In this essay, Lockhart argues that the way mathematics is typically taught in schools is fundamentally flawed and detrimental to students' understanding and appreciation of the subject. He criticizes the emphasis on rote memorization, standardized testing, and the mechanical application of formulas, which he believes stifles creativity and the inherent beauty of mathematics.
A predictive dialer is an automated telephone dialing system used primarily in call centers to increase the efficiency of outbound calling. It works by automatically dialing a list of phone numbers and routing the answered calls to available agents. The main features and functions of predictive dialers include: 1. **Automated Dialing**: Predictive dialers automatically dial multiple numbers simultaneously and connect answered calls to available agents, minimizing wait times.
Skills-based routing is a strategy used in customer service and contact center environments to match incoming inquiries or requests to the most qualified agent or representative based on their specific skills and expertise. This approach ensures that customers receive assistance from agents who are best equipped to address their needs efficiently. ### Key Components of Skills-Based Routing: 1. **Skill Identification**: Agents are assigned specific skills or competencies based on their training, experience, and areas of expertise.
Telemarketing fraud is a type of scam where criminals use phone calls to solicit money or personal information from individuals under false pretenses. This form of fraud can take various forms, including: 1. **Prize Scams**: Scammers inform victims that they have won a prize but need to pay fees or taxes to claim it. 2. **Charity Scams**: Fraudsters impersonate legitimate charities or claim to represent organizations in order to solicit donations.
A virtual queue is a system that allows customers to reserve their place in line without having to physically wait in line. Instead of lining up in front of a service point—such as a restaurant, theme park, or retail store—customers can check in or register through a mobile app or website. Once in the virtual queue, they receive updates about their position, estimated wait times, and notifications when it’s their turn to be served. **Key Benefits of Virtual Queues:** 1.
Dextrose equivalent (DE) is a measure that quantifies the extent of hydrolysis of starch or other carbohydrates into simpler sugars, primarily glucose or dextrose. The DE value indicates the relative degree of polymerization of the carbohydrate. Specifically, it is defined as the percentage of reducing sugars (expressed as dextrose) available in a sample compared to the total carbohydrate content, multiplied by 100.
An electronvolt (eV) is a unit of energy commonly used in the fields of particle physics, nuclear physics, and quantum mechanics. It is defined as the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt. 1 eV is equivalent to approximately \(1.602 \times 10^{-19}\) joules.
Zeroisation is a security procedure employed to eliminate or render inoperable sensitive information stored in electronic devices, memory, or other storage media. This process typically involves overwriting the data with zeroes or random values, ensuring that the original information cannot be recovered or accessed after the operation. Zeroisation is often used in contexts where classified or sensitive data is handled, such as in military or government environments, to prevent unauthorized access in case a device is lost or compromised.
Gram per cubic centimetre (g/cm³) is a unit of density, which measures how much mass of a substance is contained in a given volume. Specifically, it indicates how many grams of a substance are present in one cubic centimetre of that substance. 1 g/cm³ is equivalent to 1,000 kg/m³ in the metric system. The density of a substance can provide important information about its properties and behavior.
The classical electron radius, often denoted by \( r_e \), is a theoretical value that represents a length scale associated with the size of an electron based on classical physics principles. It can be derived from the electron's charge and mass, along with fundamental constants.
The mass of an electron is approximately \(9.109 \times 10^{-31}\) kilograms. In atomic mass units (amu), this is about \(5.485 \times 10^{-4}\) amu. The electron's mass is a fundamental property, essential for understanding various phenomena in physics and chemistry, such as atomic structure and the behavior of electrical currents.
The Madelung constant is a numerical factor that arises in the study of ionic crystals, specifically in the calculation of the electrostatic potential energy of an ion in a crystal lattice. It quantifies the influence of all the other ions surrounding a particular ion on the potential energy of that ion due to Coulombic interactions. In ionic crystals, ions are arranged in a regular lattice structure, and each ion interacts with numerous other ions.
Phonomotor is a term often associated with a concept or technology related to sound and movement. However, it is commonly linked to the field of linguistics and cognitive science, particularly in studies involving speech perception, phonetics, and language acquisition. In some contexts, "phonomotor" may refer to mechanisms or processes that engage auditory stimuli (like sounds or speech) to trigger or influence motor responses.
A physical constant is a quantity with a fixed value that does not change in time or space. These constants are fundamental in the laws of physics and are used to describe the properties of the universe. Examples of physical constants include: 1. **Speed of Light (c)** - Approximately \(299,792,458\) meters per second in a vacuum. 2. **Gravitational Constant (G)** - Approximately \(6.
The Rydberg constant is a fundamental physical constant that characterizes the wavelengths of spectral lines in many chemical elements, particularly hydrogen. It is named after the Swedish physicist Johannes Rydberg, who formulated a formula in the 1880s to predict the wavelengths of the spectral lines of hydrogen.
"Cotyla" could refer to several things depending on the context, but it is not widely recognized or established in common knowledge as of my last update in October 2023. It might refer to: 1. **Biological Term**: In biological contexts, "cotyla" can refer to a shallow, cup-shaped structure, such as a cavity or socket in anatomical terminology.
The Subject Alternative Name (SAN) is an extension to the X.509 specification that allows users to specify additional host names for a single SSL certificate. It was introduced to avoid the limitations of the Common Name (CN) field in SSL certificates. The SAN field can include multiple values, which may consist of: 1. **DNS Names**: Additional domain names (e.g., www.example.com, example.org). 2. **IP Addresses**: Specific IP addresses associated with the certificate.
The "blue hour" refers to the period of twilight after sunset or before sunrise when the sky takes on a deep blue hue. This phenomenon occurs when the sun is below the horizon but still illuminates the atmosphere, scattering the shorter wavelengths of light. The blue hour is particularly favored by photographers and artists because of the soft, diffused light it creates, which can enhance the mood and color of the landscape.

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.
