Progress in Optics is a well-known series of scholarly books that focus on various topics within the field of optics and photonics.
Quasioptics is a branch of optics that deals with the propagation of electromagnetic waves, particularly in the microwave and millimeter-wave frequency ranges, using techniques and principles that are somewhat distinct from traditional optics. While conventional optics typically focuses on visible light and involves the study of lenses, mirrors, and geometric optics, quasioptics emphasizes the wave nature of electromagnetic radiation and often utilizes structures that behave like optical components but operate at longer wavelengths.
An arpeggio is a musical technique where the notes of a chord are played in succession, rather than simultaneously. This creates a flowing, melodic sound, as the individual notes are articulated one after the other. Arpeggios can be played on various instruments, including piano, guitar, and other string and keyboard instruments. In music notation, arpeggios are often indicated with a zigzag line (or a wavy line) under or above the chord symbol.
Summarit is a brand of camera lenses manufactured by Leica. It primarily refers to a series of high-quality, compact lenses designed for Leica cameras, known for their sharpness, contrast, and pleasing bokeh. Summarit lenses are often favored by photographers for their performance and build quality, making them suitable for both amateur and professional photographers. The Summarit line typically includes various focal lengths and apertures, catering to different photography styles and needs.
"Summilux" is a designation used by Leica, the renowned German manufacturer of cameras and lenses, to refer to a specific series of high-quality lenses. Summilux lenses are known for their exceptional optical performance, fast maximum apertures, and build quality. The term "Summilux" typically indicates a lens with a maximum aperture of f/1.4, allowing for better low-light performance and shallow depth of field effects.
A two-color system is a classification or representation method that utilizes two distinct colors to convey information, differentiate categories, or indicate statuses. This system can be applied in various fields, including: 1. **Graphic Design and Art**: Two-color palettes are often used in design for simplicity and striking visual impact. This approach emphasizes contrast and can create a bold aesthetic.
A "list of ornaments" can refer to various types of decorative items used for enhancing the aesthetic appeal of objects, spaces, or individuals. The specifics of the list can vary based on context—such as holidays, interior design, fashion, etc. Here are some general categories and examples that might be included in a list of ornaments: ### Home and Interior Ornaments 1.
Origamic architecture is a creative art form that combines elements of origami (the Japanese art of paper folding) and architecture. It involves the use of folded paper to create three-dimensional architectural structures and designs. This technique allows artists to design intricate models that can represent buildings, landscapes, or fantastical designs in a way that emphasizes both detail and dimensionality.
Paper craft refers to a range of artistic activities that involve creating objects or decorations using paper. This can include a variety of techniques and styles, such as: 1. **Origami**: The traditional Japanese art of folding paper into intricate shapes and figures, such as animals, flowers, or geometric forms. 2. **Papercutting**: A technique where designs are cut out of paper to create intricate images and patterns. This can be done by hand with scissors or using a craft knife.
A paper popper is a simple, hand-held device made from paper or plastic that creates a popping sound when it is quickly snapped or pulled apart. It usually consists of a folded paper design that can be manipulated to create a sudden release of air, resulting in the popping noise. Paper poppers are often used as noise-makers or party favors and can be a fun and engaging craft project for children. They are sometimes used in various activities or events to add excitement or to entertain.
A permutation automaton is a theoretical model in computer science and automata theory that deals with the concept of permutations and their representation using states and transitions. The idea revolves around automata systems that can recognize or compute permutations of input sequences. While specific definitions and characteristics can vary, the general concept includes the following components: 1. **States**: A permutation automaton consists of a finite set of states. Each state can represent a specific arrangement or ordering of elements.
Kaldor–Hicks efficiency is a concept in welfare economics used to evaluate economic allocations and policy changes. It represents a criterion for judging the desirability of an allocation of resources or a policy decision based on the potential for wealth creation and redistribution.
Bogdan A. Dobrescu is a theoretical physicist known for his work in the field of high-energy physics, particularly in areas related to particle physics, supersymmetry, and collider physics. His research often involves exploring extensions of the Standard Model of particle physics and investigating implications of these theories for experiments conducted at particle accelerators like the Large Hadron Collider (LHC).
As of my last update in October 2023, "Chiang Ti Ming" does not reference a widely recognized concept, individual, or cultural term in English or other major contexts. It is possible that it might relate to a specific cultural concept, name, or term in Chinese or another language that is less commonly known or used regionally.
Jocelyn Monroe is an adult film actress known for her work in the adult entertainment industry. She gained popularity for her performances and has built a following in that sector.
Method ringing is a technique used in change ringing, specifically in the ringing of bells. It involves ringing a series of changes (or sequences) in which the order of the bells changes according to a specified method or pattern. Each method has its own distinct pattern of changes, and these are often defined mathematically. In method ringing, a specific set of rules dictates how the bells are to be rung, resulting in a predetermined sequence that can vary in complexity.
"Braids" can refer to a few different concepts depending on the context: 1. **Hairstyle**: In fashion and grooming, braids are a method of weaving strands of hair together to create intricate hairstyles. Common types of braids include a traditional three-strand braid, fishtail braid, crown braid, and Dutch braid, among others. Braids can be used for various looks, from casual to formal.
As of my last knowledge update in October 2023, there is no widely known or significant individual, place, or topic specifically named "Manuella Vincter." It's possible that this could refer to a lesser-known person, a character from a work of fiction, or perhaps a term that has emerged after my last update.
Oreste Piccioni is not widely recognized in public databases or mainstream media as of my last knowledge update in October 2021. It's possible that Oreste Piccioni could refer to a figure in a specific professional field, a local personality, or perhaps a character in literature or media.
Sookyung Choi is not widely recognized in public databases or notable sources, as of my last training cut-off in October 2023. It's possible that Sookyung Choi could refer to a private individual, a specific professional, or an emerging personality in fields such as academia, arts, or business.

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.
