Interval edge coloring is a concept from graph theory that involves coloring the edges of a graph such that no two edges that share a common vertex (are adjacent) can receive the same color. More specifically, in the interval edge coloring of a graph, the edges are assigned colors in such a way that the colors form contiguous intervals.
A Lyman-break galaxy (LBG) is a class of distant galaxy observed in the early universe, typically characterized by a significant drop in ultraviolet (UV) light at wavelengths shorter than the Lyman limit (approximately 121.6 nanometers). This Lyman limit corresponds to the transition of hydrogen atoms from their ground state to a higher energy state.
MACS J1423.8+2404 (often abbreviated to MACS 1423-z7p64) is a distant galaxy cluster located in the constellation of Virgo. It is particularly interesting to astronomers because it contains a significant number of very distant galaxies, which can provide insights into the early universe. The cluster is notable for the discovery of some of the most distant and faint galaxies ever observed, helping researchers study the formation and evolution of galaxies in the early cosmos.
"From Bacteria to Bach and Back: The Evolution of Minds" is a book written by the philosopher Daniel Dennett, published in 2017. In this work, Dennett explores the evolution of consciousness and the nature of the mind. He presents his arguments about how minds can evolve from simple biological systems, like bacteria, to complex human thought and creativity, exemplified by achievements such as composing music, represented by Bach.
The Sociology of Scientific Knowledge (SSK) is a field of study that examines the social processes and contexts that influence the production, dissemination, and validation of scientific knowledge. It emerged in the mid-20th century, influenced by the work of sociologists and philosophers who were interested in understanding how social factors shape scientific practices, theories, and the acceptance of scientific knowledge.
Optical glass is a type of glass specifically designed to manipulate light in various optical applications. It has unique properties that make it suitable for use in lenses, prisms, and other optical components. The characteristics of optical glass include: 1. **High Transparency**: Optical glass is designed to have minimal absorption of light in the visible spectrum, ensuring that as much light as possible passes through without distortion.
An electric motor is a device that converts electrical energy into mechanical energy through the interaction of magnetic fields and current-carrying conductors. Electric motors operate based on electromagnetic principles and are commonly used in various applications, ranging from household appliances to industrial machinery. ### Key Components of an Electric Motor: 1. **Stator**: The stationary part of the motor that produces a magnetic field. It typically consists of coils of wire wound around a core.
The Lakatos Award is a distinguished recognition in the field of philosophy of science. It was established in 2002 by the London School of Economics (LSE) in memory of the Hungarian philosopher Imre Lakatos, who made significant contributions to the philosophy of mathematics and science. The award is given annually to a research project or a book that makes a notable contribution to the philosophy of science.
"Not even wrong" is a phrase coined by physicist Wolfgang Pauli, often used to describe a theory or idea that is so far from reality or empirical evidence that it cannot even be classified as incorrect. Essentially, it implies that the argument or hypothesis is so misguided that it fails to meet the basic criteria for being considered a legitimate scientific theory; it's not just wrong, but fundamentally misguided.
A Ramsey sentence is a specific type of formal statement used in logic and philosophy to express the essential content of a theory without committing to the specific nature of its unobservable entities. Named after the philosopher Frank P. Ramsey, a Ramsey sentence allows for the formulation of a theory in a way that abstracts away from underlying assumptions about the existence or nature of the theoretical entities involved.
Cruising, in the context of driving, typically refers to the practice of driving a vehicle slowly and leisurely, often in a specific area such as a downtown district, a beach, or a popular gathering spot. People often cruise to socialize, show off their cars, enjoy the scenery, or simply for entertainment. Cruising can take various forms, such as: 1. **Casual Driving**: Vehicles are driven around in circles or along a stretch of road.
Aviation schools are educational institutions that offer programs and training related to the aviation industry. These schools provide a wide range of courses, catering to various aspects of aviation, including piloting, aircraft maintenance, air traffic control, aviation management, and other related fields. ### Types of Programs Offered: 1. **Pilot Training**: - Private Pilot License (PPL) - Commercial Pilot License (CPL) - Airline Transport Pilot License (ATPL) - Instrument Rating 2.
"Portal" can refer to a couple of different things in the context of computers and gaming, but it most commonly pertains to a critically acclaimed video game developed by Valve Corporation. Released in 2007 as part of the game bundle "The Orange Box," Portal is a puzzle-platform game that introduces a unique gameplay mechanic based around the use of a "portals" to solve puzzles and navigate through the game's environment.

The Macintosh operating systems refer to the various versions of operating systems developed by Apple Inc. for its Macintosh line of computers. The most widely known operating system in this family is **macOS** (formerly known as OS X and Mac OS X), which is the current operating system that powers Apple's Mac computers. **Key points about Macintosh operating systems:** 1. **Early Days**: The first Macintosh operating system, known as System Software, was released in 1984 with the original Macintosh.
"The Mote and the Beam" is a phrase derived from a biblical passage in the Gospel of Matthew, specifically Matthew 7:3-5. The verse uses the metaphor of a mote, or a speck, and a beam, or a plank, to illustrate the concept of hypocrisy in judgment.

The Book of Muhammad's Ladder, also known as "The Ladder of Muhammad" or "Mi'raj" in Arabic, refers to a significant event in Islamic tradition that describes the night journey (Isra) and ascension (Mi'raj) of the Prophet Muhammad. This journey is believed to have occurred in the year 620 CE and holds great religious importance for Muslims.
Richard Karp’s seminal 1972 paper, "Reducibility Among Combinatorial Problems," identified 21 specific problems that are NP-complete, which means they are among the most challenging problems in computational complexity theory. Below is a list of these 21 problems: 1. **Clique Problem**: Given a graph \( G \) and an integer \( k \), is there a complete subgraph (clique) of size \( k \)?

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!
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.
