G_1_14 — Archaeometry — Physical Science Methods in Archaeology

Archaeometry — the application of physical and chemical science methods to archaeological materials — encompasses a broad range of analytical techniques used to determine the composition, provenance, manufacturing techno

G_1_07 — Stable Isotope Analysis and Ancient Diets

Stable isotope analysis of human and animal remains — primarily the measurement of carbon ($\delta^{13}$C), nitrogen ($\delta^{15}$N), and sulfur ($\delta^{34}$S) isotope ratios in bone collagen, tooth enamel, hair kerat

G_1_17 — Experimental Replication of Ancient Technologies

Experimental replication — the systematic recreation of ancient objects, structures, and processes using materials, tools, and techniques available in the past — is a core methodology in experimental archaeology, enablin

G_1_06 — Paleoproteomics — Ancient Proteins Beyond DNA

Paleoproteomics is the extraction, identification, and analysis of ancient proteins from archaeological and paleontological materials — an emerging molecular method that extends biological identification far beyond the t

G_1_11 — Underwater Remote Sensing — Multibeam, Magnetometry, Sub-Bottom Profiling

Underwater remote sensing encompasses a suite of geophysical survey technologies — multibeam echosounder (MBES), side-scan sonar (SSS), magnetometry, and sub-bottom profiler (SBP) — that enable archaeologists, oceanograp

G_1_09 — Provenance Analysis: Strontium, Lead, and Oxygen Isotope Sourcing

Isotopic provenance analysis has revolutionized archaeology by enabling researchers to determine where an artifact was made, where a person grew up, what they ate, and how far they traveled — all from the chemical signat

G_1_19 — Acoustic Archaeology: Sound Mapping of Ancient Structures

Acoustic archaeology (archaeoacoustics) is an emerging interdisciplinary field that investigates the sonic properties of ancient structures, landscapes, and artifacts to understand how past peoples experienced and manipu

G_3_04 — Schumann Resonance & Frequency Claims

Schumann resonances (~7.83 Hz fundamental) are Tier 1 atmospheric physics — experimentally verified electromagnetic standing waves in the Earth-ionosphere cavity (Schumann 1952, Balser & Wagner 1960). The numerical coinc

G_3_25 — Decolonizing Knowledge Systems: Epistemic Justice and Cognitive Liberation

Decolonizing knowledge systems is a global intellectual and political movement arguing that the dominance of Western-origin epistemology in universities, research institutions, and international organizations is not a ne

G_3_15 — Piezoelectric Effects: Crystals, Geology, and Ancient Technology

Piezoelectricity (from Greek piezein, "to squeeze") is the physical phenomenon whereby certain crystalline materials generate an electric charge when subjected to mechanical stress, and conversely, deform mechanically wh

G_3_21 — Critical Realism: Roy Bhaskar and Stratified Ontology

Critical realism is a philosophical movement founded by Roy Bhaskar (1944–2014) that proposes a stratified ontology — reality consists of three nested domains (the Real, the Actual, and the Empirical) — and argues that s
