Pappus's chain is a geometric construct that consists of an infinite sequence of circles, each of which is tangent to both a common line and the previous circle in the sequence. The chain is named after the ancient Greek mathematician Pappus of Alexandria, who is credited with studying such arrangements. In more detail, the construction starts with a given circle tangent to a line. The next circle in the chain is drawn such that it is tangent to both the line and the first circle.
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.
CatSper4 is a protein that is part of the CatSper (Cation channel of sperm) family of ion channels, which are critical for sperm motility and fertility in many animals, including humans. These channels primarily facilitate the influx of calcium ions (Ca²⁺) into sperm cells, which is essential for various physiological processes, including sperm activation, movement, and the ability to fertilize an egg.
KCNQ4 is a gene that encodes a potassium ion channel, which is part of the KCNQ (Kv7) family of voltage-gated potassium channels. These channels are important for the regulation of electrical activity in various tissues, particularly in the nervous system and the inner ear. KCNQ4 specifically plays a critical role in the auditory system, where it helps to control the membrane potential of hair cells in the cochlea.
TRPM2 (Transient Receptor Potential Melastatin 2) is a member of the TRP (Transient Receptor Potential) ion channel family, which is known for its role in various physiological processes, including the sensation of temperature, pain, and other stimuli.
F2 propagation refers to a type of radio wave propagation that occurs in the high-frequency (HF) band, particularly in the ionosphere. The F2 layer is the highest region of the ionosphere, typically found at altitudes between about 200 to 400 kilometers (approximately 124 to 248 miles) above the Earth's surface. It is characterized by high electron densities, which can facilitate long-distance radio communications.
Fast Atom Bombardment (FAB) is a technique used in mass spectrometry for the ionization of samples, particularly those that are non-volatile and thermally labile. Unlike traditional ionization methods, FAB allows the analysis of larger biomolecules, such as proteins, peptides, and other complex organic compounds. In the FAB process, a sample is typically dissolved in a suitable solvent and then bombarded with a beam of energetic atoms, often xenon or argon.
Laser diode thermal desorption (LDTD) is a technique used primarily in analytical chemistry and mass spectrometry for the desorption and ionization of sample analytes. This method utilizes the focused energy from a laser diode to heat a sample material, causing the analytes to desorb from the surface of a solid or liquid matrix into the gas phase. ### Key Components of LDTD: 1. **Laser Diode**: A laser device that emits light at specific wavelengths.
Matrix-assisted laser desorption electrospray ionization (MALDI-ESI) is a mass spectrometry technique that combines two powerful ionization methods: matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization (ESI). This hybrid technique is utilized to analyze a wide range of biomolecules, including proteins, peptides, and other large biomolecular complexes.
The Kennelly–Heaviside layer, also known as the E layer of the ionosphere, is a region in the Earth's upper atmosphere that is characterized by a high concentration of ionized particles. This layer is located approximately 30 to 100 kilometers (18 to 62 miles) above the Earth's surface and plays a significant role in radio wave propagation.
"Waleed Al-Salam" appears to refer to a specific person or concept that may not be widely recognized outside of a particular context. It's possible that it could be a name associated with a public figure, an institution, or a cultural reference. However, without further details, it's difficult to provide a precise answer.
"Irish relativity theorists" typically refers to physicists or researchers from Ireland who have made contributions to the field of relativity, which includes both the special and general theories of relativity developed by Albert Einstein in the early 20th century. While there isn't a formal or specific group known by that name, several notable Irish scientists and mathematicians have worked in the fields related to theoretical physics and relativity.
Edmund Edward Fournier d'Albe was a notable figure in the fields of physics and astronomy. He was born in 1865 and passed away in 1933. D'Albe is often recognized for his work on various scientific topics, particularly in the study of celestial mechanics and the physics of motion. One of his notable contributions was related to the analysis and understanding of comets. He made several predictions regarding their trajectories and behaviors, which garnered attention in the scientific community at the time.
Irrational rotation refers to a concept in mathematics, particularly in the field of dynamical systems and geometry. It typically involves rotations by an angle that is an irrational multiple of \( \pi \), meaning that the rotation angle cannot be expressed as a simple fraction. ### Key aspects of irrational rotation: 1. **Continuous Rotation**: When an object (like a point on a circle or a plane) is rotated continuously by an irrational angle, it never returns to its original position.
The Paducah Gaseous Diffusion Plant (PGDP) is a facility located in Paducah, Kentucky, that was primarily used for the enrichment of uranium for use in nuclear fuel.

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.
