Henry Holiday refers to an English painter, illustrator, and stained glass artist who lived from 1839 to 1927. He is best known for his illustrations of Lewis Carroll's "The Hunting of the Snark" and "The Adventures of Alice in Wonderland." Holiday's work is characterized by its detailed and whimsical style, which captures the imaginative essence of Carroll's stories.

"In the Shadow of the Dreamchild" is a book written by the British author and scholar, *Jude J. O'Connell*. It explores the life and legacy of Lewis Carroll, particularly focusing on his relationship with Alice Liddell, the inspiration for his famous character Alice in "Alice's Adventures in Wonderland." The book delves into the complexities of their relationship, the impact of Carroll's works, and the cultural and historical context of his life.

The Lewis Carroll Society of North America (LCSNA) is an organization dedicated to the study and appreciation of the works of Lewis Carroll, the author of classic literary works such as "Alice's Adventures in Wonderland" and "Through the Looking-Glass." Founded in 1979, the society aims to promote interest in Carroll's life, works, and contributions to literature, mathematics, and other fields.

Mark Burstein is known as an editor and has been involved in various publishing projects, particularly related to literature and arts. He is recognized for his work in curating and editing collections of writings, and his contributions often encompass a range of genres.

As of my last knowledge update in October 2021, life expectancy can vary over time due to factors such as health care quality, lifestyle, and social conditions. However, I don't have access to the most current data or specific rankings by year. As of 2021, generally, countries in Europe with the highest life expectancy included: 1. **Switzerland** 2. **Spain** 3. **Italy** 4. **Norway** 5. **Iceland** 6.

As of my last knowledge update in October 2021, life expectancy in Mexico can vary significantly by state due to factors such as health care access, socio-economic conditions, diet, and lifestyle. Generally, states with better economic conditions and healthcare services tend to have higher life expectancies. Typically, states like Mexico City, Nuevo León, and Jalisco have been known for higher life expectancies, while some southern states may report lower figures.

As of my last update in October 2023, life expectancy data can vary somewhat based on the source and the year of the report. Generally, the World Health Organization (WHO), the United Nations (UN), and the World Bank are reliable sources for this information. Typically, countries with the highest life expectancy often include: 1. **Japan** 2. **Switzerland** 3. **Singapore** 4. **Spain** 5. **Italy** 6. **Australia** 7.

A lift chair is a type of recliner designed to assist individuals, particularly the elderly or those with mobility challenges, in standing up and sitting down safely. The chair is equipped with a motorized mechanism that tilts the seat forward and lifts the user up to a standing position, making it easier for them to get out of the chair without excessive strain. Lift chairs typically come with various reclining positions, allowing users to adjust the backrest and footrest for their comfort.

A carrying pole, also known as a yoke or a shoulder pole, is a long, sturdy pole or beam used to carry loads, typically by balancing the load at either end. This tool is often employed in manual labor, particularly in agricultural and hauling contexts. The carrying pole is designed to rest on the shoulders of the individual carrying it, with weights or containers suspended from either end of the pole.

The term "Derrick" can refer to several things depending on the context: 1. **Engineering and Construction**: A derrick is a type of crane that is typically used for lifting heavy loads. It consists of a framework that supports a pulley and is often used in construction sites or for marine applications.

An overhead crane, also known as a bridge crane, is a type of material handling equipment used to lift and move heavy loads horizontally and vertically within a facility. It consists of a hoist mechanism, a set of traveling wheels, and a bridge that spans the distance between two supporting structures, such as columns or walls.

There are several fictional characters across various media who possess the ability to manipulate light. Here are some notable examples: 1. **Green Lantern (Hal Jordan)** - In the DC Comics universe, Hal Jordan wields a power ring that can create constructs of light. He can manipulate light to various degrees, using it for offense, defense, and even creating illusions.

Standard illuminants are defined reference light sources that serve as a model for the color of light in various applications, particularly in color science, photography, and visual arts. They provide a consistent basis for comparing the color characteristics of different light sources and are essential for ensuring accurate color representation and reproduction. The most commonly referenced standard illuminants are defined by the International Commission on Illumination (CIE).

Visible Light Communication (VLC) is a wireless communication technology that uses visible light to transmit data. This method leverages the visible spectrum, typically between 400 and 700 nanometers, to send information through modulated light sources, such as LEDs (light-emitting diodes).

A bumpy torus is a mathematical concept that refers to a toroidal surface (the shape of a doughnut) that has irregular, wavy, or non-smooth features instead of a perfectly smooth form. In differential geometry and topology, a torus is typically defined as a product of two circles, \(S^1 \times S^1\).

Color mixing is the process of combining different colors to create new colors. There are two primary methods of color mixing: additive mixing and subtractive mixing. 1. **Additive Color Mixing**: This method involves the combination of light colors. When light of different colors is combined, it creates new colors. The primary colors in additive mixing are red, green, and blue (RGB). When these colors of light are mixed together in varying intensities, they produce all other colors.

The daylight factor is a measure used in architecture and building design to assess the amount of daylight that penetrates a space, particularly in interior areas. It indicates the illumination level provided by natural light compared to the amount of daylight available outdoors. The daylight factor is expressed as a percentage and is calculated by comparing the internal illuminance at a specified point in a room with the outdoor illuminance under overcast sky conditions.

Relativistic aberration is a phenomenon predicted by the theory of relativity that describes how the observed direction of light from an object changes depending on the relative motion between the observer and the source of the light at relativistic speeds (that is, speeds comparable to the speed of light).

Spin angular momentum of light refers to a property associated with the polarization of light waves. In quantum mechanics, photons, the quantum particles of light, possess both orbital and spin angular momentum. 1. **Definition**: - The spin angular momentum of light is fundamentally related to the intrinsic angular momentum of the photon, which arises from its polarization state. While photons are massless particles, they still have spin, which can take on discrete values.

Spontaneous Parametric Down-Conversion (SPDC) is a quantum optics process in which a single photon interacts with a nonlinear crystal to produce two lower-energy photons, commonly referred to as "signal" and "idler" photons. This process is significant in quantum mechanics and quantum optics, as it is one of the primary methods for generating entangled photon pairs, which are essential for various applications in quantum information science, such as quantum cryptography, quantum computing, and quantum teleportation.
