The Longest Increasing Subsequence (LIS) is a well-known problem in computer science and mathematics that involves finding the longest subsequence of a given sequence of numbers where the elements of the subsequence are in strictly increasing order. A subsequence is a sequence derived from another sequence by deleting some elements without changing the order of the remaining elements.
Canister shot is a type of ammunition used in cannons and artillery that consists of a container filled with small projectiles, such as iron balls or metal shards. When fired, the canister breaks open and disperses its load over a wide area, functioning much like a giant shotgun blast. This makes it particularly effective against clusters of enemy troops, unarmored vehicles, or for close-range engagement.
A crossbow bolt, also known as a quarrel, is a projectile designed specifically for use with a crossbow. Unlike traditional arrows used with longbows or recurve bows, bolts are typically shorter, heavier, and have a thicker shaft, which allows them to withstand the high velocity and tension produced by crossbows. Key features of crossbow bolts include: 1. **Length**: They are generally shorter than traditional arrows, usually ranging from about 16 to 22 inches in length.
Impact depth generally refers to the depth of penetration or the degree to which an object impacts or affects another object or a surface upon collision or contact. The term can be used in various contexts, including physics, geology, and engineering, and its specific definition can vary depending on the field of study.
A pellet in the context of air guns refers to a small projectile designed to be used with air rifles and air pistols. Typically made of lead, though sometimes constructed from materials like alloy or plastic, pellets are engineered for accuracy and consistency. They come in a variety of shapes and sizes, the most common being: 1. **Diabolo Shape**: This is the most popular type, characterized by a narrow waist and expanded head, which helps stabilize flight and improve accuracy.
Round shot refers to a type of projectile that was historically used in cannons and artillery during the 18th and early 19th centuries. It is a solid, spherical projectile made of iron or other metal, designed to be fired from smoothbore cannons. Unlike explosive shells or canister shots, round shot does not contain an explosive charge; instead, it relies on its mass and velocity to cause damage upon impact.
Alfred Msezane is not widely known in popular culture or history, so there may be limited context available regarding him.
Bill Price is a physicist known for his work in the field of experimental physics. He has made contributions to areas such as quantum mechanics, solid-state physics, and other related topics. However, there might not be extensive public information available about him compared to more widely recognized figures in physics. For specific achievements or publications, further context or details about his work would be helpful.
Charles H. Townes (1915-2015) was an American physicist best known for his pioneering work in the development of the laser and maser (Microwave Amplification by Stimulated Emission of Radiation). He shared the 1964 Nobel Prize in Physics with Nikolay Basov and Alexander Prokhorov for their contributions to the field of quantum electronics.
Henry Fox Talbot was a British scientist, inventor, and photography pioneer, best known for his contributions to the development of photography in the 19th century. Born on February 11, 1800, Talbot was one of the first to create a method for producing photographs using a chemical process. In 1834, he developed a technique called "calotype," which involved the use of paper coated with silver iodide to create a latent image that could be developed into a negative.
Isidor Isaac Rabi (1898–1988) was an influential American physicist best known for his work in the field of atomic and nuclear physics. He was awarded the Nobel Prize in Physics in 1944 for his invention of the method of resonance, which is a technique used to measure the magnetic properties of atomic nuclei. Rabi's contributions also played a significant role in the development of magnetic resonance imaging (MRI) and various applications in quantum mechanics.
Janina Kneipp is a contemporary figure known for her work in the field of wellness, particularly in relation to natural healing and holistic health practices. She is often associated with the Kneipp philosophy, which is based on the principles developed by Sebastian Kneipp, a 19th-century priest and naturopath. These principles focus on water therapy, herbal remedies, nutrition, exercise, and balance in life.
Joseph von Fraunhofer (1787–1826) was a German physicist and optical engineer who made significant contributions to the field of optics. He is best known for his work in the development of high-quality optical instruments, particularly telescopes and microscopes. Fraunhofer is especially renowned for his discovery of the Fraunhofer lines—dark lines in the solar spectrum that result from the absorption of specific wavelengths of light by elements in the Sun's atmosphere.
Lucia Reining is a physicist known for her work in the field of computational materials science and quantum mechanics. She has contributed significantly to the understanding of electronic structure methods, particularly in the context of many-body systems and the application of advanced computational techniques in materials modeling. Reining's research often focuses on developing and applying methods to study properties of materials at the atomic level, including phenomena related to electronic correlations and excitations.
Michael Morris is an oceanographer known for his research in marine sciences, specifically in the areas of ocean circulation, climate dynamics, and the impact of environmental changes on marine ecosystems. He may be involved in various studies related to oceanographic data collection, modeling, and analysis. His work can contribute to our understanding of climate change, ocean health, and the interconnectedness of ocean systems.
Philip Bunker is not widely recognized as a prominent public figure, historical person, or concept based on the information available up to October 2023. It's possible that the name may refer to a specific individual who is not widely known, or it could relate to a context that has emerged after my last update.
Richard J. Saykally is a prominent American physical chemist known for his research in the areas of molecular spectroscopy and the study of water. He has made significant contributions to understanding the structure and dynamics of water molecules and has been involved in advanced studies of the molecular interactions in various environments. Saykally has been a faculty member at the University of California, Berkeley, where he has taught and mentored many students.
Robert G. Greenler is a notable figure in the field of optics and spectroscopy. He is known for his contributions to the understanding of light scattering and the development of various optical instruments and techniques.

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.
