ZD_4_06 — Mathematical Sociology and Network Analysis
Mathematical sociology applies formal mathematical models — graph theory, probability, game theory, dynamical systems, and statistical mechanics — to understand social structures, collective behavior, and institutional d
ZD_4_11 — Social Network Analysis — Granovetter, Small Worlds, Influence
Social network analysis (SNA) — the study of social structures through the use of graph theory and network science, where individuals (or organizations, nations, etc.) are represented as nodes and their relationships (fr
ZD_2_01 — Machine Learning Mathematics
Machine learning — the science of algorithms that improve through experience — rests on a rich mathematical foundation spanning optimization, statistics, linear algebra, probability, and functional analysis. The core mat
L_4_03 — Genetic Clocks and Molecular Dating
The molecular clock — the concept that DNA and protein sequences accumulate mutations at approximately regular rates over time — provides a powerful tool for dating evolutionary divergences independently of the fossil re
L_4_02 — Mendel, Inheritance, and the Rediscovery of Genetics
Gregor Johann Mendel (1822–1884), an Augustinian friar at the St. Thomas Abbey in Brno (then part of the Austrian Empire), conducted the foundational experiments in genetics by systematically crossing garden pea plants (
L_4_09 — Selective Sweeps and Positive Selection in Humans
A selective sweep occurs when a beneficial allele rises rapidly in frequency under positive natural selection, carrying nearby linked variants along with it (genetic hitchhiking) and reducing genetic variation across the
L_2_02 — Population Genetics and Hardy-Weinberg Equilibrium
Population genetics — the mathematical study of allele frequency change in populations — provides the quantitative framework underlying evolutionary biology. The Hardy-Weinberg principle (1908), independently derived by
L_3_16 — Genomic Imprinting & Evolutionary Conflict
Genomic imprinting — the epigenetic phenomenon in which a subset of genes (~100–200 in mammals) are expressed from only one parental allele, with the other allele silenced by DNA methylation and histone modification esta
L_5_10 — Neandertal Introgression: Which Genes and Why They Persisted
When modern humans (Homo sapiens) migrated out of Africa ~60,000-70,000 years ago and encountered Neanderthals (Homo neanderthalensis) in western Asia and Europe, the two species interbred — and the genetic legacy of tha
Y_4_05 — Dreams, Dream Incubation, and Oneiric Knowledge
Dreams have been treated as a source of knowledge, prophecy, and divine communication in virtually every civilization. Ancient Mesopotamians maintained professional dream interpreters (šāʾilu) and compiled dream omen com
Y_5_07 — Phenomenology of Pain and Pain Modulation
Pain — defined by the International Association for the Study of Pain (IASP, revised 2020) as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissu
Y_2_03 — Reincarnation Research — Stevenson, Tucker, Past-Life Memories
Reincarnation research — the systematic, empirical investigation of claims that individuals (typically young children) possess verified memories of previous lives — represents one of the most methodologically rigorous pr
Y_2_06 — Dissociation, Depersonalization, and Derealization
Dissociation — the disruption of normally integrated functions of consciousness, memory, identity, emotion, perception, behavior, and sense of self — represents one of the most revealing natural experiments for understan
Y_2_11 — Déjà Vu and Anomalous Memory Experiences
Déjà vu — from the French "already seen" — is the subjective, compelling sensation that a present experience has been previously encountered, despite the experiencer's knowledge that the situation is objectively novel. F
Y_2_08 — Anesthesia, Consciousness, and Awareness
General anesthesia — the pharmacological induction of unconsciousness, amnesia, analgesia, and immobility — is one of the most profound alterations of consciousness that humans routinely produce, yet how anesthetics actu
Y_3_01 — Kundalini and Serpent Energy Traditions
Kundalini ("coiled one" in Sanskrit) describes a dormant serpent-like energy said to reside at the base of the spine, which, when "awakened" through meditation, breathwork, or spontaneous experience, rises through a cent
Y_3_08 — Breathwork and Holotropic States of Consciousness
Deliberate manipulation of breathing patterns to alter consciousness is among the oldest and most widespread human practices, documented in yogic pranayama (circa 500 BCE, Yoga Sutras of Patanjali), Tibetan tummo (inner-
P_3_08 — Pragmatism — American Philosophy
Pragmatism is the most distinctive American contribution to philosophy, originating in the 1870s with Charles Sanders Peirce (1839–1914), developed by William James (1842–1910), and extended by John Dewey (1859–1952). It
P_3_06 — Plato — Forms, Cosmology, and the Philosophical Tradition
Plato (428/427–348/347 BCE) is the foundational figure of Western philosophy, whose dialogues established the frameworks for metaphysics (Theory of Forms), epistemology (knowledge as recollection), political philosophy (
P_4_01 — Death and the Afterlife Across Cultures
Every known human culture has developed beliefs about what happens after death — making afterlife cosmology one of the most universal features of human thought. The major frameworks include: judgment and reward/punishmen
