{{BloomIntro}}
Archaeology is the study of human history and prehistory through the excavation of sites and the analysis of artifacts and other physical remains. It is the "detective work" of the past. While history relies on written documents (which can be biased or incomplete), archaeology relies on the material reality of what people left behind—their tools, their homes, their garbage, and even their bones. By piecing together these fragments, archaeologists can reconstruct the lives of people who lived thousands of years ago, revealing the rise and fall of civilizations and the long journey of human evolution.

* '''Archaeology''' — The study of the human past through material remains.
* '''Artifact''' — An object made or used by a human (e.g., a spearhead, a piece of pottery).
* '''Ecofact''' — Organic material found at a site that has archaeological significance (e.g., seeds, animal bones).
* '''Feature''' — A non-portable part of an archaeological site (e.g., a wall, a hearth, a burial pit).
* '''Excavation''' — The systematic digging and recording of an archaeological site.
* '''Stratigraphy''' — The study of the layers (strata) of soil and debris; older layers are usually at the bottom.
* '''Survey''' — The process of finding and mapping archaeological sites from the surface.
* '''Radiocarbon Dating (C14)''' — A method for determining the age of organic materials by measuring the decay of carbon isotopes.
* '''Lidar''' — A remote sensing method using laser light to map features hidden under dense forest or soil.
* '''Assemblage''' — A group of artifacts found together in a specific context.
* '''Site''' — A place where evidence of past human activity is preserved.
* '''Midden''' — An ancient trash heap (one of the most valuable sources of info).
* '''In Situ''' — An object found in its original place of deposition.
* '''Context''' — The exact position and relationship of an artifact to other artifacts and features.

== <span style="color: #FFFFFF;">Understanding</span> ==
Archaeology is about '''Context''', not just "Treasure."

'''1. The Law of Superposition''': In an undisturbed site, the stuff at the bottom is older than the stuff at the top. This allows archaeologists to create a "Timeline" of how a culture changed.

'''2. Cultural Materialism''': Archaeologists look at "The Stuff" to understand "The Mind." If a grave contains gold and servants, we know the society was stratified. If we find fish bones in a desert, we know there was a trade network or a change in climate.

'''3. Types of Archaeology''':
* '''Prehistoric''': Studying societies before the invention of writing.
* '''Classical''': Studying the civilizations of Greece and Rome.
* '''Underwater''': Excavating shipwrecks and sunken cities.
* '''Historical''': Studying recent periods where written records exist (e.g., Colonial America).

'''Archaeology is Destructive''': Every time you excavate a site, you destroy it. Therefore, archaeologists spend 10% of their time digging and 90% of their time recording and analyzing. If the context is lost, the artifact is just a "pretty stone."

'''Modeling 'Radiocarbon Decay' (Dating the past):'''
<syntaxhighlight lang="python">
def estimate_age(carbon_percentage):
    """
    C14 has a half-life of ~5,730 years.
    """
    import math
    half_life = 5730
    # Formula: Age = (ln(perc/100) / ln(0.5)) * half_life
    if carbon_percentage <= 0: return "Infinite age (too old for C14)"
    
    age = (math.log(carbon_percentage / 100) / math.log(0.5)) * half_life
    return round(age)

# Found a piece of wood with 25% C14 remaining
print(f"Estimated Age of sample: {estimate_age(25)} years")
# This is how we know 'exactly' when a site was occupied.

; Iconic Discoveries
: '''The Rosetta Stone''' → The key to deciphering Egyptian hieroglyphs.
: '''The Terracotta Army''' → 8,000 life-sized statues protecting the tomb of the first Chinese Emperor.
: '''Pompeii''' → A Roman city frozen in time by a volcanic eruption, providing a "snapshot" of daily life.
: '''Göbekli Tepe''' → The world's oldest known temple (12,000 years old), challenging our ideas about the origin of civilization.

'''The Concept of "Processual" vs. "Post-Processual" Archaeology''': 
* '''Processualists''' see archaeology as a hard science (looking for laws of human behavior).
* '''Post-Processualists''' see it as more like history (focusing on the individual's experience and the symbolic meaning of objects). Analyzing this debate helps us understand that "The Past" is always something we construct in the present.

== <span style="color: #FFFFFF;">Evaluating</span> ==
Evaluating an archaeological claim:
# '''Contextual Integrity''': Was the object found in a clean layer, or has the soil been mixed by roots or looting?
# '''Methodological Rigor''': Was every bucket of soil screened for tiny seeds and beads?
# '''Ethical Responsibility''': Did the researchers consult with the modern descendants of the people they are studying (e.g., NAGPRA in the US)?
# '''Conservation''': How will the artifacts be preserved once they are removed from the ground?
