Logical form refers to the abstract structure of statements or arguments that highlights their logical relationships, irrespective of the specific content of the statements. It serves to represent the underlying logic of a statement or argument in a way that clarifies validity, inference, and logical consistency. In linguistics and philosophy, the notion of logical form is often used to analyze natural language sentences to reveal their syntactic and semantic properties.
Truth value is a concept used in logic and mathematics to determine the veracity of a statement or proposition. In classical logic, a statement is assigned one of two truth values: 1. **True**: The statement accurately reflects reality or the conditions it describes. 2. **False**: The statement does not accurately reflect reality or the conditions it describes. Some logical systems have more than two truth values.
The Axiom of the Empty Set is a fundamental concept in set theory, which states that there exists a set that contains no elements. This set is called the empty set, denoted by the symbol ∅ or {}. Formally, the Axiom of the Empty Set asserts: There exists a set \( \emptyset \) such that for any element \( x \), \( x \notin \emptyset \).
The Axiom of Infinity is one of the axioms of set theory, particularly in the context of Zermelo-Fraenkel set theory (ZF), which is a foundational system for mathematics. The Axiom of Infinity asserts the existence of an infinite set. Specifically, the axiom states that there exists a set \( I \) such that: 1. The empty set \( \emptyset \) is a member of \( I \).
The Axiom of Pairing is a fundamental concept in set theory, particularly in the context of Zermelo-Fraenkel set theory (ZF). It is one of the axioms that helps to establish the foundations for building sets and functions within mathematics. The Axiom of Pairing states that for any two sets \( A \) and \( B \), there exists a set \( C \) that contains exactly \( A \) and \( B \) as its elements.
The Axiom Schema of Specification (also known as the Axiom Schema of Separation) is a fundamental principle in set theory, particularly in the context of Zermelo-Fraenkel set theory (ZF). It is one of the axioms that govern how sets can be constructed and manipulated within this framework. In essence, the Axiom Schema of Specification allows for the creation of a new set by specifying a property that its elements must satisfy.
The "Wholeness Axiom" is often associated with the field of mathematics, particularly in discussions around set theory and certain formal systems. It posits that a collection of objects, or a set, is considered whole if it contains all the elements of interest without exceptions or omissions. In a broader philosophical or conceptual framework, the Wholeness Axiom can be interpreted as asserting that a system is complete when it encapsulates all necessary components or properties within it.
The Association for Logic, Language and Information (LLI) is an academic organization that promotes research and collaboration in the fields of logic, language, and information. It aims to foster interdisciplinary connections and the exchange of ideas among researchers and practitioners from diverse areas including linguistics, computer science, philosophy, cognitive science, and artificial intelligence. The LLI often organizes conferences, workshops, and other events where scholars can present their work, exchange ideas, and discuss current trends and challenges in these fields.
In the context of mathematics, "Set theory stubs" typically refers to short articles or entries related to set theory that are incomplete or provide a minimal amount of information. This term is often used in collaborative online encyclopedias or databases, such as Wikipedia, where contributors can help to expand these stubs by adding more detailed content, references, and examples. Set theory itself is a fundamental branch of mathematical logic that studies sets, which are collections of objects.
In the context of decision trees or certain types of graphical models in machine learning and statistics, the "honest leftmost branch" typically refers to a branch or decision path that is made based on the most straightforward or direct criteria without embellishment or bias. Here's a basic breakdown of how this concept might apply: 1. **Decision Trees**: In decision trees, branches represent decisions that lead to outcomes.
SOBER-128 is a stream cipher that was developed as part of the SOBER family of cryptographic algorithms. It was designed for high-speed encryption and decryption, particularly in environments where performance is critical. The "128" in its name refers to the size of the key, which is 128 bits.
Melvin Fitting is a notable figure in the field of mathematical logic, particularly known for his work in model theory and the philosophy of logic. He has contributed significantly to the understanding of how logical systems can be applied to various structures, as well as the relationships between different logical frameworks. Fitting is perhaps best known for his development of the "Fitting semantics," which pertains to the study of non-monotonic logics and their applications.
A stream cipher is a type of encryption algorithm that encrypts data one bit or one byte at a time, rather than encrypting blocks of data as in block ciphers. In a stream cipher, plaintext is combined with a pseudorandom key stream to produce ciphertext. This process is typically achieved using techniques such as the XOR (exclusive OR) operation.
Takeuti's conjecture is a hypothesis in the field of mathematical logic, specifically related to set theory and the study of ordinal numbers. It was proposed by the Japanese logician Genjiro Takeuti in the context of the properties of the ordinals and their representations.
William Lane Craig is a contemporary Christian philosopher, theologian, and apologist, known for his contributions to the philosophy of religion and the defense of theism. He was born on July 23, 1949, and has been influential in discussions surrounding the existence of God, especially through his formulation of the Kalam cosmological argument. Craig holds a Ph.D. in Philosophy from the University of Birmingham and a theological degree from Talbot School of Theology.
Albert Wohlstetter (1913-1997) was an influential American economist and strategist known for his work in the fields of nuclear strategy, defense policy, and international relations. He was a prominent figure in shaping U.S. strategic policy during the Cold War and is best known for his advocacy of a robust and flexible nuclear deterrent. Wohlstetter served as a consultant and advisor for various U.S.
Whitehead's theory of gravitation refers to the ideas developed by the philosopher and mathematician Alfred North Whitehead in the early 20th century. While he is primarily known for his work in philosophy, particularly process philosophy, he also made contributions to the understanding of physics, including gravitational theory. Whitehead's approach to gravitation is distinct from the more widely known theories of gravity, such as Newton's law of universal gravitation and Einstein's general theory of relativity.
Pinned article: ourbigbook/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.
