Van Jacobson is a notable figure in computer networking, renowned primarily for his contributions to the development of network protocols, particularly in the areas of TCP (Transmission Control Protocol) and congestion control. He is perhaps best known for the "Jacobson congestion control algorithm," which introduced techniques for managing network congestion. His work in the late 1980s and early 1990s led to significant improvements in the performance and reliability of TCP, particularly in handling packet loss and managing throughput in network communications.
The term "anxiety of influence" was coined by literary critic Harold Bloom in his 1973 book **"The Anxiety of Influence: A Theory of Poetry."** Bloom's concept revolves around the idea that poets and writers experience a deep-seated anxiety stemming from their awareness of the influence of previous authors on their work. This creates a tension between the desire to be original and the inevitable impact that earlier literary figures have on their writing.
Dirk van Dalen is a prominent Dutch mathematician and computer scientist known for his work in the fields of logic, computer science, and particularly in the area of proof theory and type theory. He has made significant contributions to the development of the logical foundations of computer science, including the refinement of typed lambda calculus and contributions to the study of proof assistants and formal verification. Van Dalen is also recognized for his efforts in promoting the field of logic and mathematics through various educational initiatives and writings.
Ethical intuitionism is a philosophical position in meta-ethics which suggests that individuals have a natural ability to perceive moral truths through intuition. This view holds that moral knowledge is not derived solely from empirical evidence or rational thought, but instead comes from an innate sense of right and wrong. Key features of ethical intuitionism include: 1. **Moral Intuition**: Proponents argue that moral judgments are often immediate and intuitive rather than the result of conscious reasoning.
The PEG ratio, or Price/Earnings to Growth ratio, is a financial metric used to evaluate a stock's valuation relative to its earnings growth rate. It is calculated by taking the Price-to-Earnings (P/E) ratio and dividing it by the expected growth rate of the company’s earnings (typically over the next 5 years).
Return on Equity (ROE) is a financial metric that measures the profitability of a company in relation to shareholders' equity. It indicates how effectively management is using a company's assets to create profits. ROE is an important measure for investors and analysts because it shows how well a company is generating returns on the equity invested by shareholders.
Time to Value (TTV) refers to the duration it takes for a product, service, or solution to provide tangible benefits or value to a customer after they have made a purchase or engaged with it. This concept is particularly important in various industries, including software as a service (SaaS), where customers expect to see results quickly after implementation. A shorter TTV means that a customer can realize the benefits of their investment sooner, leading to higher satisfaction and potentially improved retention rates.
In Occitan literature, a "tornada" refers to a specific poetic form that is characterized by a structured, often repetitive pattern. It typically consists of a series of stanzas that include a refrain or recurring line, similar to what is found in other lyric poetry traditions. The term is most often associated with the medieval troubadour tradition, where poets (troubadours) would compose songs with intricate rhyme schemes and melodies.
NGC 2626 is a bright emission nebula located in the constellation Carina. It is noted for its striking appearance and is part of a region of active star formation. The nebula is often associated with a young, massive star that ionizes the surrounding gas and dust, causing it to emit light. As an emission nebula, NGC 2626 glows due to the excitation of its gas, primarily hydrogen, by ultraviolet light from the nearby hot stars.
IC 2177, also known as the "Lizard Nebula," is an emission nebula located in the constellation Monoceros, which is also known as the Unicorn. This nebula is part of a larger complex of clouds and is situated relatively close to our solar system, at a distance of approximately 2,000 light-years.
Cygnus OB9 is a region in the constellation Cygnus that is notable for its association with a group of bright, massive stars known as an OB association. OB associations are collections of stars that are primarily composed of spectral types O and B, which are the hottest and most luminous classes of stars. These stars are typically short-lived, burning through their nuclear fuel relatively quickly compared to cooler stars like the Sun.
Cygnus X is a prominent area in the constellation Cygnus, known for being one of the most important and studied regions of the sky in terms of high-energy astrophysics. It is primarily recognized for containing a series of X-ray binaries, which are star systems that emit X-rays due to the interaction of a neutron star or black hole with a companion star.
"DR 6" could refer to various things depending on the context. Without specific context, it's hard to determine its exact meaning. Here are a few possibilities: 1. **Disaster Recovery (DR) Plan**: In IT and business continuity, "DR 6" might refer to a particular stage or version of a disaster recovery plan.
The Omega Nebula, also known as Messier 17 (M17) or the Swan Nebula, is a bright emission nebula located in the constellation Sagittarius. It is one of the most actively studied star-forming regions in the Milky Way. Here are some key features of the Omega Nebula: 1. **Distance and Size**: The Omega Nebula is approximately 5,000 light-years away from Earth and has a diameter of about 15 light-years.
NGC 6164/6165, commonly referred to as N44, is an emission nebula located in the constellation Dorado, which is part of the Large Magellanic Cloud (LMC), a nearby galaxy to our own Milky Way. N44 is notable for its striking appearance and significant size, encompassing an area that is approximately 1,500 light-years across.
LH 95, also known as "LHS 95," is a star system located in the constellation of Octans. It is notable for having a confirmed exoplanet, LHS 95 b, which is a Super-Earth that orbits its star. The system is of interest in astronomical studies due to its characteristics that are often compared to those of our own solar system and the potential for studying exoplanet atmospheres.
NGC 2264 is a notable open star cluster located in the constellation Monoceros, which is often referred to as the Unicorn. It is distinguished by its two primary components: the Cone Nebula, a prominent dark nebula, and the Christmas Tree Cluster, which contains several bright, young stars. NGC 2264 is approximately 2,600 light-years away from Earth and is known for its rich star formation activity.
NGC 281 is a bright emission nebula located in the constellation Cassiopeia. It is sometimes referred to as the "Pacman Nebula" due to its distinctive shape, which resembles the character from the classic video game. The nebula is an area of active star formation and contains a cluster of young stars known as IC 1590, which illuminate the surrounding gas and dust.
NGC 346 is a young and actively forming star cluster located in the Small Magellanic Cloud (SMC), a satellite galaxy of the Milky Way. It is situated in the constellation Tucana and is known for being one of the most prominent star-forming regions in the SMC. NGC 346 contains a significant number of young, hot stars and is surrounded by a nebula rich in gas and dust, which serves as the material from which new stars can form.

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.
