Comprehensive Study Guide: Science, Technology, and Society (STS) and Historical Developments

Fundamentals of Science, Technology, and Society

Scientific Principles and Methods

Etymology and Definition of Science:
- Derived from the Latin word scientia, meaning "knowledge".
- Refers to any systematic body of knowledge or practice acquired through scientific inquiry and research.
- Represents the human attempt to understand the natural world (including phenomena such as gravity, atoms, plants, and animals) with or without concern for practical applications.
- Focuses on discovering facts and relationships to construct coherent theories that explain natural phenomena.
The Scientific Method:
- A set of objective techniques used to investigate natural phenomena and analyze empirical data to reach valid conclusions.
- Sequential Steps of the Scientific Method:
  1. Identify the Problem
  2. Information / Background Gathering
  3. Formulate a Hypothesis
  4. Testing / Data Gathering (Experimentation)
  5. Conclusion
  6. Result Analysis
Case Example of the Scientific Method (Nena's Detergent Selection):
- Problem: Nena wanted to determine which detergent brand sold at the local sari-sari store was the best.
- Background Information: She interviewed local housewives to identify their top choices, narrowing down the options to four brands: Malinis, Maputi, Mabango, and Matipid.
- Hypothesis: Nena hypothesized that Maputi, being the most expensive brand, would perform best.
- Testing/Data Gathering: She used one detergent brand per wash session and recorded observations regarding: duration of product usability, pleasantness of smell after washing, and effectiveness in stain/dirt removal.
- Conclusion & Result: Malinis was proven to be the best detergent because it lasted longer, yielded the most pleasant scent, and removed dirt faster than the other three options. This demonstrated that the most expensive product is not necessarily the best.

Technological Principles and Practical Applications

Etymology and Definition of Technology:
- Derived from two Greek words: techne (skill, craftsmanship, or art) and logos (discourse or reason).
- Defined as the human attempt to alter or manipulate the physical world through the creation and utilization of material artifacts.
- Operates as a human activity on the same societal tier as politics, economics, and art.
- Encompasses tools, techniques, and practical procedures required to execute scientific findings.
Practical Example of Technological Procedure (Chicken Adobo Standardization):
- Ingredients:
  - $1\,\text{kg}$ chicken legs (approximately $9\,\text{pieces}$ )
  - $4\,\text{tbsp}$ soy sauce (or more to taste)
  - $3\,\text{cloves}$ crushed garlic
  - $4\,\text{pieces}$ dried bay leaves
  - $\frac{1}{4}\,\text{cup}$ cooking oil
  - $2\,\text{tbsp}$ vinegar
  - $1\,\text{cup}$ water
  - $\frac{1}{2}\,\text{tbsp}$ white sugar
  - $\frac{1}{2}\,\text{tsp}$ salt
  - Whole peppercorns
- Cooking Procedure:
  1. In a large container, combine soy sauce and crushed garlic; marinate the chicken for at least $1\,\text{hour}$ .
  2. Heat cooking oil in a pan over medium heat.
  3. Sear the marinated chicken in hot oil, browning all sides for approximately $5\,\text{minutes}$ .
  4. Pour in the remaining marinade and water; bring the mixture to a boil.
  5. Add dried bay leaves and whole peppercorns.
  6. Simmer for $20\text{--}30\,\text{minutes}$ until the chicken becomes tender.
  7. Add vinegar, stir, and allow to cook uncovered for $10\,\text{minutes}$ .
  8. Stir in sugar and salt, then extinguish the heat source.

Interconnection Between Science and Technology

Science explores the natural world for the primary purpose of knowing.
Technology explores material resources for the primary purpose of making something useful out of scientific knowledge.
Science drives technology by uncovering fundamental breakthroughs that make new technological applications possible.

The Major Intellectual and Scientific Revolutions

Nature of Intellectual and Scientific Revolutions

Intellectual Revolution: Historical transformations in thoughts, beliefs, and social institutions driven by the introduction of new ideas and principles. These represent paradigm shifts that challenge widely accepted scientific and philosophical doctrines.
Scientific Revolution: An intellectual revolution where science and technology form the core focus. It also refers to the historical era during the Middle Ages and early modern period when scientific inquiry gained widespread influence over society.
Classical Foundations: Early pre-Socratic Greek thinkers were the first to explain natural phenomena using physical laws rather than supernatural myths involving gods and heroes, establishing the foundational role of mathematics and empirical observation.

The Copernican Revolution

Core Concepts:
- Nicolaus Copernicus, a Polish astronomer and mathematician, proposed the Heliocentric Model of the universe in opposition to the Geocentric Model.
- Geocentric Model: Formulated by Claudius Ptolemy and Aristotle, supported by religious institutions for over $1400\,\text{years}$ , posited that the Earth was the stationary center of the universe.
- Heliocentric Model: Asserted that the Sun is the stationary center of the universe, and the Earth is merely one of several celestial bodies orbiting it.
Societal Impact:
- Shifted societal reliance away from astrology toward astronomy. In medieval society, astrology was viewed as an essential science, and astrologers cast horoscopes to maintain institutional support from the Church.
- Demoted Earth from a supernatural, unique position to an equal status with other planetary bodies.
- Paved the way for subsequent figures including Tycho Brahe, Johannes Kepler, and Galileo Galilei to establish mathematical foundations for celestial mechanics.
- Galileo Galilei's telescopic observations popularized science but resulted in his lifelong house arrest by religious authorities following charges of heresy.

The Darwinian Revolution

Core Concepts:
- Charles Darwin, an English naturalist, authored On the Origin of Species and The Descent of Man.
- Introduced the theory that species evolve over time through the mechanism of Natural Selection, contradicting traditional creationist accounts.
Key Principles of Natural Selection:
1. Variation: Genetic variations exist within a population and can be passed down to offspring.
2. Overproduction & Competition: Population growth leads to resource scarcity and competition for survival.
3. Adaptation: Organisms possessing beneficial structural or functional adaptations are more likely to survive and reproduce.
4. Selection: Over multiple generations, allele frequencies change within the population, leading to evolutionary modification.
Societal Impact:
- Established that human beings are biological entities subject to the natural laws of science rather than unique, supernatural creations.
- Demonstrated biological continuity, placing humans on an equal taxonomical footing with other living organisms.
- Laid the groundwork for evolutionary biology, which was confirmed through Gregor Mendel's discoveries in genetics, giving rise to the modern Neo-Darwinian Synthesis.

The Freudian Revolution

Core Concepts:
- Sigmund Freud, an Austrian neurologist, founded psychoanalysis as a clinical method for treating psychopathology through systematic dialogue.
- Challenged the Enlightenment concept of human absolute rationality, establishing that human behavior is heavily driven by unconscious and subconscious processes.
Topographical Model of the Mind:
- Conscious Mind: Thoughts, feelings, and perceptions currently focused on in the present moment.
- Preconscious Mind: Latent memory stores that can be readily retrieved into conscious awareness.
- Subconscious / Unconscious Mind: Storage of primitive desires, repressed memories, and instinctive impulses.
Structural Model of Personality:
- Id: Operates entirely in the unconscious mind under the pleasure principle; contains Eros (the life/survival instinct) and Thanatos (the death/destructive instinct).
- Ego: Operates under the reality principle across conscious and unconscious states, finding socially acceptable avenues to satisfy the drives of the Id.
- Super-ego: Operates under moral imperatives, enforcing social rules and ethical standards.
Ego Defense Mechanisms:
- Repression: Unconscious filtering of disturbing or traumatic thoughts from entering consciousness (e.g., repression of aggressive impulses during the Oedipus complex).
- Denial: Outright refusal to acknowledge or process painful external realities (e.g., a habitual smoker refusing to acknowledge health risks).
- Projection: Attributing one's own unacceptable feelings, motives, or impulses onto another person (e.g., believing someone hates you when you harbor hatred for them).
- Displacement: Transferring emotional reactions or aggressive drives onto a vulnerable target object or person (e.g., kicking a domestic pet after a frustrating workday).
- Regression: Reverting to behaviors characteristic of an earlier developmental stage under stress (e.g., a hospitalized child displaying thumb-sucking behaviors).
- Sublimation: Converting socially unpalatable drives into constructive activities (e.g., channeling innate physical aggression into competitive sports).
Dream Interpretation:
- Asserted that dreams are direct manifestations of the unconscious mind driven by unfulfilled desires and linked to personal experiences.

The Information Revolution

Core Concepts:
- Represents radical shifts in the social, economic, and political structures of human society driven by developments in information acquisition, processing, and dissemination.
Historical Phases:
1. Invention of Language: Provided the primary evolutionary differentiator for early humans, enabling complex social cohesion.
2. Invention of Writing: Enabled record-keeping, law enforcement, and the formal rise of urban civilizations.
3. Invention of Printing: Allowed mass reproduction of scientific, philosophical, and religious texts (e.g., Copernicus' De revolutionibus orbium coelestium and Gutenberg Bibles).
4. Digital & Computing Era: Electronic computers automated complex mathematical calculations, optical fibers created high-speed communications, and digital networks established the modern Internet.
Socioeconomic Impacts:
- Workplace Flexibility: Introduced telecommuting (remote work using computers, telephones, and electronic mail), allowing flexible work hours and reducing physical geographic constraints.
- Information Risks: The rapid spread of information can be exploited to disseminate incorrect data, fake news, and propaganda, causing public misinformation.

- Invention: Bamboo/Leaf Letters ("Pamatid")
  - Details: Messages carved into bamboo scrolls, banana leaves, or tree bark, rolled up and bound with natural fibers. Tribal communities also used pamatid (knotted strings) to convey specific messages.
  - Antecedents: Lack of paper pulp materials and the need to send messages across mountainous regions and rivers.
Food:
- Invention: Rice Terraces of the Cordilleras
  - Details: Built by the Ifugao people on steep mountain slopes, these stone and mud terraces rely on intricate irrigation systems fed by mountain forests. Designated a UNESCO World Heritage cultural landscape site in 1995, featuring five clusters: Batad and Bangaan (in Banaue), Mayoyao (in Mayoyao), Hungduan, and Kiangan.
  - Antecedents: The necessity of sustaining rice production in steep, mountainous terrain.

- Invention: Kalesa
  - Details: A two-wheeled horse-drawn carriage constructed from local timber and bamboo, serving as primary urban transit during Spanish and American eras.
  - Antecedents: The need for short-distance transport suitable for narrow, cobble-paved streets.
Trade:
- Invention: Pre-Colonial Barter System & Maritime Ports
  - Details: Direct trade exchanging indigenous goods (gold, pearls, spices, natural timber) for foreign goods from China, Arabia, and India. Pre-colonial trade terms included palit (to trade goods), bakas (business partner), gasa (discount), and tunay (cash purchasing).
  - Antecedents: The archipelagic geography of the Philippines, which required maritime trade network connections.
Adaptation:
- Invention: Bahay Kubo (Nipa Hut)
  - Details: An indigenous stilt house built using bamboo, nipa palm leaves, and cogon grass, featuring raised living quarters above flood level.
  - Antecedents: Frequent typhoons, heavy monsoon flooding, high humidity, and the need for low-cost, repairable housing.
Protection:
- Invention: Kampilan
  - Details: A double-handed, single-edged cutlass sword featuring a flared blade tip and carved hardwood pommel depicting a buaya (crocodile), bakunawa (sea serpent), kalaw (hornbill), or kakatua (cockatoo).
  - Antecedents: Inter-tribal warfare, coastal piracy, and the need to defend local coastal settlements (barangays).
Entertainment:
- Invention: Tinikling Folk Dance
  - Details: A dance where performers hop and step between rhythmically clapped bamboo poles accompanied by stringed Rondalla music. The dance movements imitate the tikling bird dodging traps in rice paddies.
  - Antecedents: The need to unwind after hard agricultural labor, build community, and preserve cultural stories.
