Free logic is a type of logical system that is designed to handle the semantics of statements that may involve non-existent objects. Unlike classical logic, which typically assumes that every term in a statement refers to an existing object in the domain of discourse, free logic allows for the possibility that some terms may not refer to anything at all.
Probabilistic Logic Networks (PLNs) are a type of statistical model that combines principles from logic programming and probabilistic reasoning. They are designed to handle uncertainty in knowledge representation and reasoning, allowing for both deterministic logic and probabilistic inference to coexist. ### Key Features of Probabilistic Logic Networks: 1. **Logical Structure**: PLNs typically involve a set of logical statements or predicates that represent knowledge about a domain. These predicates can be true or false, similar to traditional logic programming.
The "Battle of the Sexes" is a classic example in game theory that illustrates a coordination problem between two players who prefer different outcomes but still want to coordinate their actions. The game highlights the tension between individual preferences and the benefit of cooperation.
The Centipede game is a classic arcade video game that was originally developed by Atari and released in 1980. It combines elements of shooting and strategy and is well known for its colorful graphics and fast-paced gameplay. In the game, players control a small shooter located at the bottom of the screen and must shoot at a centipede that descends from the top of the screen down towards the player.
A coordination game is a type of game in game theory where players benefit from making the same choices or coordinating their strategies. In these games, the players have a common interest in achieving a particular outcome, meaning their success hinges on their ability to align their actions with one another. Key characteristics of coordination games include: 1. **Multiple Equilibria**: Coordination games often have multiple equilibria, meaning there are several outcomes that players can coordinate on.
In game theory, a deadlock is a situation in which two or more players (or agents) are unable to reach an agreement or make progress because each party is waiting for the other to take action or make a concession. This concept is often used in the context of strategic interactions where competing interests prevent resolution. A classic example of a deadlock can be observed in negotiations, such as labor disputes or political negotiations, where each party holds firm on their position, leading to a standstill.
A sequence motif is a short and recurring pattern of nucleotides in DNA or RNA, or of amino acids in proteins, that has a biological function or significance. In molecular biology, motifs can be thought of as recognizable sequences that may indicate the presence of specific structural or functional characteristics.
The Lewis signaling game is a theoretical framework developed by philosopher David Lewis in his 1969 paper "Convention." It models communication and the development of meaning in language through the interaction of individuals in a simple game structure. The game illustrates how agents can create a convention for communication despite having no inherent understanding of the signals they use. ### Key Components of the Lewis Signaling Game: 1. **Players**: There are typically two players in the game: a sender and a receiver.
The Public Goods Game is a standard economic experiment used to study cooperation and social dilemma situations in game theory. It involves a group of participants who have the option to contribute to a public good, which benefits all players regardless of their individual contributions. Here's how the game typically works: 1. **Participants**: A fixed number of players, often ranging from 4 to 10.
Fission products are the nuclei that are produced when a heavy nucleus undergoes nuclear fission. During the fission process, a heavy atomic nucleus, such as uranium-235 or plutonium-239, absorbs a neutron and becomes unstable, leading it to split into two or more smaller nuclei. This splitting releases a significant amount of energy, along with additional neutrons that can further propagate the fission reaction.
A "truel" is a term used to describe a situation involving three participants who are attempting to shoot each other, similar to a duel, which typically involves two. In a truel, the participants engage in an interaction where they each take turns trying to eliminate one another, often with varying levels of skill or intent.
"Tit for tat" is a strategy used in game theory, specifically in the context of repeated games, such as the Iterated Prisoner's Dilemma. The strategy involves players responding to each other's actions by reciprocating in kind. If one player cooperates, the other player will also cooperate in the next round. Conversely, if one player defects or betrays, the other player will do the same in the next round.
The term "American physicists" refers to individuals from the United States who study or work in the field of physics, which is the branch of science concerned with the nature and properties of matter and energy. American physicists have made significant contributions to various areas of physics, including theoretical physics, experimental physics, condensed matter physics, astrophysics, and more.
Nuclear fallout refers to the radioactive particles that are released into the atmosphere following a nuclear explosion or accident. These particles can settle on the ground, contaminate air and water, and have significant effects on ecosystems. Here are some of the primary effects of nuclear fallout on ecosystems: 1. **Radiation Exposure**: Organisms exposed to high levels of radiation can experience acute health effects, including radiation sickness, and long-term consequences such as cancer, genetic mutations, and reduced reproductive success.
Extended Irreversible Thermodynamics (EIT) is a theoretical framework that extends classical irreversible thermodynamics to better describe systems far from thermodynamic equilibrium. Traditional irreversible thermodynamics, as developed by figures like Lars Onsager and Ilya Prigogine, typically operates under the assumption that systems are near equilibrium. In these cases, transport processes (such as heat conduction and diffusion) are linear and can be described effectively by linear differential equations.
Nikos Kyrpides is a prominent scientist and researcher known for his work in the fields of microbiology, bioinformatics, and systems biology. He has contributed significantly to the understanding of microbiome research and environmental genomics. One of his notable roles was as a program director at the U.S. Department of Energy's Joint Genome Institute, where he has been involved in various projects related to microbial ecology and the analysis of genome sequences.
Loschmidt's paradox is a thought experiment associated with the second law of thermodynamics, which states that the total entropy of an isolated system can only increase over time. The paradox is named after the Austrian physicist Johann Georg Loschmidt, who raised a significant question regarding the nature of molecular motion and the irreversibility of thermodynamic processes. The core of Loschmidt's paradox lies in the behavior of microscopic particles governed by classical mechanics.
The Second Law of Thermodynamics is a fundamental principle that governs the behavior of energy and entropy in physical systems. It can be stated in several ways, but one of the most common formulations is that in any energy transfer or transformation, the total entropy of an isolated system can never decrease over time. Instead, it will either increase or remain constant in reversible processes.
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.
