Humans: Monogamy and Parental Care
Humans: Monogamy and Parental Care 1. Monogamy Social Monogamy: Culturally common across many societies. One long-term partner for companionship, parenting, and social structure. Can coexist with extra-pair mating. Sexual Monogamy: One sexual partner at a time. Less frequent across lifetime; varies culturally and individually. Genetic Monogamy (biological exclusivity): Rare in strict sense. Genetic studies show occasional non-paternity events. 2. Courtship & Mating Symbolic a...

Inference Rules with Story Examples
Inference Rules with Story Examples Inference rules are logical rules used to derive conclusions from premises. In propositional logic, they help us move from one set of statements (premises) to a valid conclusion. Here's an explanation of common inference rules using simple story examples. 1. Modus Ponens (Affirming the Antecedent) Rule: If "p → q" is true, and p is true, then q must also be true. Story Example: Imagine you are preparing for a meeting, and the rule is: If the meeting is ...

Logical Equivalences
Logical Equivalences Logical Equivalences refer to the relationships between two logical expressions or propositions that always have the same truth value under all possible interpretations. In other words, two logical expressions are equivalent if they produce identical truth tables. Here are some common logical equivalences used in propositional logic: 1. Double Negation Law ¬(¬p) ≡ p Explanation: The negation of a negation brings back the original proposition. Example: If p is "It is...

De Morgan's Laws – Proof by Story
De Morgan's Laws – Proof by Story First Law ¬(p ∧ q) ≡ (¬p) ∨ (¬q) Story: Let p = "I will bring an umbrella." Let q = "I will wear a raincoat." p ∧ q = "I will bring an umbrella and wear a raincoat." If I say "I will not do both" (¬(p ∧ q)), then it means: Either I don't bring the umbrella (¬p), Or I don't wear the raincoat (¬q), Or maybe both. Thus: ¬(p ∧ q) ≡ (¬p) ∨ (¬q) Second Law ¬(p ∨ q) ≡ (¬p) ∧ (¬q) Story: Let p = "I will watch TV." Let q = "I will play games." p ∨ q = "...

Comparison: Phonetic Symbols vs. Musical Notations
Comparison: Phonetic Symbols vs. Musical Notations The comparison and relationship between phonetic symbols and musical notations reveal interesting parallels in how both fields represent sound. Phonetics focuses on the articulation and qualities of speech sounds, while musical notation captures the dynamics, pitch, and rhythm of music. Below is a comparison and exploration of how the two systems relate. 1. Purpose and Function Phonetic Symbols: Represent speech sounds (phones) in a standa...

Sememe — Definition and Structure
Sememe — Definition and Structure Sememe is the minimal unit of meaning in semantics, analogous to the morpheme in morphology. It represents the atomic semantic content conveyed by a linguistic unit. A sememe is not tied to form (sound or writing), but to abstract meaning. Properties of a Sememe Abstract: Not necessarily a word or morpheme. Semantic unit: Represents a single concept or feature. Can be componential: Combined to build complex meanings. Example The word: “Man” Can...
