Force spectroscopy is a technique used to study the mechanical properties of materials at the nanoscale by measuring the forces that arise during the interaction of a probe with a sample. It typically involves a sharp tip, often mounted on a cantilever, that interacts with a sample surface. The force exerted between the tip and the sample is measured as a function of distance, allowing researchers to obtain detailed information about the sample’s mechanical properties, such as elasticity, adhesion, and friction.
Forensic engineering is a specialized field of engineering that involves the application of engineering principles and practices to investigate failures or accidents in structures, materials, and systems. The primary goals of forensic engineering are to determine the root causes of failures, gather evidence, analyze data, and provide expert testimony in legal cases. Key aspects of forensic engineering include: 1. **Investigation**: Forensic engineers conduct thorough investigations to gather information about an incident.
MAATAC (Miniature Army Tactical Combat) is a tabletop wargaming system that typically involves player-controlled miniatures representing military units in tactical warfare scenarios. Players create and command their own armies, engage in battles, and often utilize strategy, dice rolls, and various rule sets to determine the outcomes of conflicts. While there are different variations of miniatures games, MAATAC can often be characterized by its focus on realism and tactical gameplay, allowing for detailed troop movements and battlefield strategies.
As of my last knowledge update in October 2021, "TimeLogic" does not refer to a widely recognized term or concept in mainstream fields. However, there are a few possibilities that could relate to the term: 1. **Software or Technology**: TimeLogic could refer to specific software or tools used for time management, scheduling, or logical programming. Various companies may have products named "TimeLogic" that are focused on these areas.
The Chinese Remainder Theorem (CRT) is a result in number theory that provides a way to solve systems of simultaneous congruences with different moduli. It states that if you have several congruences with pairwise coprime moduli, there exists a unique solution modulo the product of those moduli. ### Formulation If \( n_1, n_2, \ldots, n_k \) are pairwise coprime integers (i.e.
Philip Wolfe is an American mathematician known for his contributions to the fields of optimization and mathematical programming. He is particularly recognized for his work on convex analysis and linear programming. Wolfe is perhaps best known for the Wolfe duality theorem, which provides conditions under which a duality relationship holds in optimization problems. He has also made significant contributions to the study of quasi-convex functions and was involved in developing important algorithms and methods used in optimization.
The Titius–Bode law, also known simply as Bode's law, is an empirical rule that suggests a pattern in the distances of the planets from the Sun in our solar system. The law states that the distances of the planets from the Sun follow a specific mathematical progression. According to the Titius–Bode law, the distance (in astronomical units, AU) of the planets can be approximated using the formula: \[ a_n = 0.4 + 0.

Tommy Flowers (1905-1998) was a British engineer and computer scientist best known for his pioneering work in electronic computing. He is widely regarded for his role in designing and building the Colossus, the world's first programmable digital electronic computer, which was used by British codebreakers during World War II to help decrypt the Lorenz-encrypted messages used by the German military.
A photoelectrochemical cell (PEC) is a device that converts light energy, typically from the sun, into chemical energy through electrochemical processes. These cells combine the principles of photovoltaics and electrolysis to facilitate chemical reactions, often utilized for applications such as solar fuel production, including hydrogen generation through water splitting. Here’s how a typical PEC works: 1. **Light Absorption**: The PEC contains a photoactive material (often a semiconducting material) that absorbs sunlight.
The photoelectrochemical (PEC) process refers to an electrochemical reaction that is driven by light, typically sunlight. This technology harnesses solar energy to facilitate chemical reactions, often for applications like water splitting to produce hydrogen or carbon dioxide reduction. Key components and principles of the PEC process include: 1. **Photocatalyst**: This is a material, often a semiconductor, that absorbs light and generates electron-hole pairs when illuminated.
"Forward measure" is a concept used in financial mathematics and quantitative finance, particularly in the context of modeling and pricing derivatives. It generally refers to a particular probability measure under which certain processes, like asset prices or tradeable instruments, exhibit specific properties over time. In mathematical finance, different measures are used to analyze stochastic processes, especially when it comes to pricing options and other derivatives.
Topological defects are irregularities or disruptions that occur in a medium where the spatial arrangement of the constituents is defined by a specific order parameter. These defects arise in various fields of physics, particularly in the study of condensed matter systems, cosmology, and field theory. They reflect a mismatch between the local symmetry of the system and the global properties of the medium.
Foucault's measurement of the speed of light refers to a famous experiment carried out by the French physicist Léon Foucault in 1850. Foucault's apparatus involved a rotating mirror and a light source. In his experiment, light was directed toward a rotating mirror, reflected off it, and then sent to a stationary mirror placed some distance away. The rotating mirror would move slightly during the time it took for the light to travel to the stationary mirror and back.
Photon antibunching is a quantum optical phenomenon that occurs when photons emitted from a source are detected in such a way that they exhibit a reduced probability of being detected in pairs (or bunches) compared to what would be expected from classical light sources. This effect is a key signature of non-classical light and is often observed in light emitted by single quantum emitters, such as single atoms, quantum dots, or single molecules.

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.
