ACS Applied Materials & Interfaces is a peer-reviewed scientific journal published by the American Chemical Society (ACS). It focuses on the study of materials science and engineering, particularly in the context of materials applied to interfaces. The journal publishes original research articles, review papers, and technical notes that address various aspects of applied materials, including their synthesis, characterization, and applications in areas such as electronics, optics, energy, and biomedicine.
During World War I, the concept of unmanned aerial vehicles (UAVs), while not fully developed as we understand them today, began to take shape with several experimental designs and projects. The British, in particular, explored various forms of these early UAVs, primarily focusing on either remote-controlled aircraft or drones intended for specific military applications, such as reconnaissance or bombing.
Diary studies are a qualitative research method used in various fields such as psychology, anthropology, user experience (UX) research, and other social sciences. In a diary study, participants are asked to regularly record their thoughts, feelings, behaviors, or experiences over a specified period of time, often in relation to a particular topic or research question.
The Carolingian monetary system refers to the currency and economic practices introduced and promoted during the Carolingian Empire, particularly under the reign of Charlemagne (reigned 768-814) and his successors. This period was marked by a significant effort to reform and standardize monetary practices across the empire, which included much of Western Europe.
"Discoveries" by Guy Soulié is a work that typically involves exploring various themes, ideas, or concepts, but specific details about the publication are not widely available.
Bcrypt is a password hashing function designed for securely storing passwords. It is designed to be computationally intensive, which helps protect against brute-force attacks and is resistant to rainbow table attacks. Bcrypt incorporates a few key features: 1. **Adaptive Cost Factor**: Bcrypt allows you to specify a cost factor that determines how computationally expensive the hashing process is. This factor can be increased as hardware improves, allowing the algorithm to remain secure over time.
Robert Boyle (1627-1691) was an Anglo-Irish philosopher, chemist, physicist, and inventor who is often referred to as one of the founders of modern chemistry. He is best known for Boyle's Law, which describes the inversely proportional relationship between the pressure and volume of a gas at constant temperature. His work laid the groundwork for the scientific method and emphasized experimentation and observation.
A gravimeter is an instrument used to measure gravitational acceleration or the strength of the gravitational field at a specific location. Gravimeters can detect small variations in gravity caused by geological structures, density changes within the Earth's crust, or even changes due to human activities. There are different types of gravimeters, including: 1. **Absolute Gravimeters**: These measure the gravitational acceleration directly by dropping a mass and measuring the time it takes to fall.
Owen Flanagan is an American philosopher, known for his work in philosophy of mind, ethics, and the philosophy of consciousness. He is a professor at Duke University and has made significant contributions to discussions about the nature of consciousness, the self, and moral psychology. Flanagan is also known for his writings that explore the intersection of philosophy with cognitive science and neuroscience.
Ana Paiva may refer to several individuals, but without specific context, it is difficult to provide a precise answer. There could be notable people named Ana Paiva in various fields such as academia, art, or sports, among others.
Nikolay Bogolyubov may refer to a few different things, but he is most notably known as a prominent Russian and Soviet theoretical physicist and mathematician, recognized for his contributions to statistical mechanics and quantum field theory. Born in 1909 and passing in 1992, he made significant advancements in various areas of physics, including the theory of superconductivity and the theory of collective phenomena in many-body systems.
A Quincunx matrix refers to a specific arrangement of points or elements that resemble the pattern of a quincunx, which is a graphical representation typically characterized by five points placed in a square or rectangle, with four points at the corners and one point in the center. However, the term can also relate to real-valued matrices used in specific mathematical contexts, such as statistics or probability.
Max Picard (1888–1965) was a Swiss author and philosopher, best known for his reflections on the nature of existence, language, and the human condition. He was particularly noted for his works exploring themes such as solitude, silence, and the spiritual aspects of life. His most famous book, "The World of Silence," delves into the significance of silence in relation to human experience and thought.
In the field of harmonic analysis and representation theory, a **Gelfand pair** is a specific type of mathematical structure that arises when studying the representations of groups. More concretely, a Gelfand pair consists of a pair of groups (typically a group \( G \) and a subgroup \( H \)) such that the algebra of \( H \)-invariant functions on \( G \) is particularly "nice" for some representation theory considerations.
An **affine connection** is a mathematical concept used primarily in differential geometry and the theory of manifolds. It provides a way to define a notion of parallel transport, which allows one to compare vectors at different points on a manifold. The affine connection also enables the definition of derivatives of vector fields along curves in a manifold.

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.
