Lahaina Noon is a phenomenon that occurs in certain tropical locations, notably in Hawaii, when the sun is directly overhead at noon. During this time, which typically occurs twice a year, objects cast little to no shadow because the sun is positioned at a 90-degree angle relative to the ground. In Lahaina, Maui, the term specifically refers to the days when the sun is directly overhead at noon, which generally falls around May 23 and July 21 each year.
Solar irradiance is the power per unit area received from the Sun's radiation, measured in watts per square meter (W/m²). It quantifies the intensity of sunlight hitting a surface at a specific location and time. Solar irradiance varies based on several factors, including the angle of sunlight, atmospheric conditions, and the time of year.
Qsort, short for "quick sort," is a highly efficient sorting algorithm that is commonly used in computer science for organizing data. Here's a brief overview of its features: 1. **Algorithm Type**: Quick sort is a divide-and-conquer algorithm. It works by selecting a 'pivot' element from the array and partitioning the other elements into two sub-arrays, according to whether they are less than or greater than the pivot.
PMUT stands for Piezoelectric Microelectromechanical Systems Ultrasonic Transducer. It is a type of transducer that converts electrical signals into ultrasonic waves (and vice versa) using piezoelectric materials. PMUTs are typically used in various applications, including medical imaging, non-destructive testing, and ultrasonic cleaning, as well as in consumer electronics such as proximity sensors and gesture recognition systems.
A "space hurricane" is a phenomenon that refers to a large, swirling structure of plasma and magnetic fields in the Earth's upper atmosphere, particularly in the ionosphere. This phenomenon was identified in a study published in 2021, which described a space hurricane that occurred in the Earth's atmosphere. The space hurricane is characterized by a cyclone-like structure, appearing similar to the hurricanes we see on Earth but occurring in the space environment.
Solid state engineering is a field that deals with the study, design, and application of solid materials, particularly semiconductors and related components. It encompasses a variety of disciplines including materials science, electrical engineering, and physics, focusing on the properties and behaviors of solid materials at the atomic or molecular level. Key areas of interest in solid state engineering include: 1. **Semiconductor Fabrication**: Designing and manufacturing semiconductor devices such as transistors, diodes, and integrated circuits.
The term "adduct" primarily refers to a type of chemical compound or molecular formation that results from the addition of two or more distinct molecules or species. In chemistry, an adduct is formed when two different substances combine, often involving the sharing of electrons or bonds. Adducts can occur in various contexts, including: 1. **Organic Chemistry**: An example is the addition of a nucleophile to an electrophile, resulting in a new compound.
A chemical transport reaction involves the movement of chemicals from one location to another, often in the context of environmental science, materials science, or chemical engineering. Such reactions can encompass various processes, such as the diffusion of reactants, the transport of pollutants in the atmosphere or water, and the movement of reactive species in different phases (gas, liquid, or solid).
The Pseudo Jahn-Teller effect is a phenomenon observed in molecular and solid-state chemistry, particularly in the context of coordination complexes and transition metal ions. It is a specific type of distortion that occurs in systems that have degenerate electronic states but lack the symmetry required for a true Jahn-Teller distortion.
"Ghost" can refer to various games, depending on the context, but one of the most notable games known as "Ghost" is "Ghost of Tsushima," which is an action-adventure game developed by Sucker Punch Productions and published by Sony Interactive Entertainment. Released in July 2020 for the PlayStation 4, the game is set in feudal Japan during the Mongol invasion of Tsushima Island in the 13th century.
"Order and Chaos" is a concept that often refers to the dichotomy between structured, predictable systems (order) and unpredictable, disorganized systems (chaos). This theme appears in various fields, including: 1. **Philosophy**: Philosophically, order and chaos can represent the fundamental aspects of existence, with order symbolizing stability, harmony, and predictability, while chaos embodies uncertainty, rebellion, and the potential for new beginnings or transformations.
"The Elements" is a song by Tom Lehrer, a renowned American singer-songwriter, and mathematician. It was released in the 1950s and is part of Lehrer's larger body of work that combines humor with educational themes. The song humorously lists the chemical elements known at the time, set to the tune of the "Major-General's Song" from Gilbert and Sullivan's "The Pirates of Penzance.
"The Old Dope Peddler" is a song by the American singer-songwriter and social activist, Tom Lehrer. It was released in 1959 as part of his album "An Evening Wastefully Spent with Tom Lehrer." The song critiques the drug trade and societal attitudes toward addiction and drug use, employing Lehrer’s signature blend of satire and humor.
Stable sorting algorithms are those that maintain the relative order of records with equal keys (or values) when sorting a list. In other words, if two elements have equal values and one appears before the other in the original input, a stable sort will ensure that the one that appeared first retains its position relative to the other in the output.
A Bitonic sorter is a parallel sorting algorithm that is particularly well-suited for hardware implementation and for use in parallel computing environments. It is based on the concept of a "bitonic sequence," which is a sequence that first monotonically increases and then monotonically decreases, or can be rotated to achieve that form.
Bogosort is a highly inefficient and deliberately impractical sorting algorithm, often used as a humorous example of a sorting method. The basic idea behind Bogosort is to generate random permutations of the list to be sorted until a sorted order is found. Here’s a brief outline of how Bogosort works: 1. Check if the array is sorted. 2. If it is not sorted, generate a random permutation of the array.
Cocktail shaker sort, also known as bidirectional bubble sort or shaker sort, is a variation of the classic bubble sort algorithm. It sorts a list by repeatedly stepping through the list to compare and swap adjacent elements. However, unlike bubble sort, which only passes through the list in one direction, cocktail shaker sort alternates directions. This allows it to move larger elements to the end of the list and smaller elements to the beginning in a single iteration.
Comparison sort is a category of sorting algorithms that operate by comparing elements to one another to determine their order. This method relies on comparing pairs of elements and deciding their relative positions based on these comparisons. The most common characteristic of comparison sorts is that they can be implemented so that the sorted order depends solely on the way elements are compared.
Cycle sort is a highly efficient, in-place sorting algorithm that is particularly notable for its minimal number of writes to the original array. It is based on the concept of finding cycles in the array and rearranging the elements in a way that each cycle is sorted correctly with minimal data movement. ### Key Characteristics of Cycle Sort: 1. **In-place**: It requires no additional storage space, making it memory efficient.
In C++, "sort" typically refers to the process of arranging elements in a particular order, usually in ascending or descending order. The C++ Standard Library provides a powerful and flexible sorting algorithm through the `std::sort` function, which is defined in the `<algorithm>` header.

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.
