Definition and Branches of Science

Study Notes

Definition of Science

Science is a systematic body of knowledge about the natural world, developed using the scientific method.

Branches of Science

Natural Sciences: Include disciplines like Biology and Physics, focusing on physical universe laws.
Social Sciences: Examine human behavior and societies, with Sociology as a key example.
Humanities: Investigate aspects of human culture, including philosophy and history.

Examples of Disciplines

Biology: Encompasses Zoology (study of animals) and Botany (study of plants).
Physics: Covers fields like Chemistry (study of substances) and Astronomy (study of celestial bodies).

Origin and Study of the Universe

Origin of the Universe: Investigated primarily through Astronomy.
Origin of Planets: Explored using Geology (study of the Earth) and Meteorology (study of weather).
End of the World Scenarios: Considerations include Nuclear war, pandemics, and ecological collapse.

First Scientific Revolution

Key Figures: Notable scientists include Galileo Galilei (telescopic innovations), Nicolas Copernicus (heliocentric model), and Charles Darwin (theory of evolution).
Contributions: Their work laid foundational principles for modern science.

Scientific Inquiry

Process: Involves forming observations, hypotheses, testing, and data analysis.
Hypothesis vs. Theory: Hypotheses are testable, while theories are comprehensive explanations.
Hypothesis Testing: Uses experimental and comparative methods to ascertain validity.

Steps of Scientific Inquiry

Problem Identification: Define a specific issue to investigate.
Research: Collect relevant data and background information.
Hypothesis Formation: Create predictive, testable statements.
Testing the Hypothesis: Execute experiments and evaluate outcomes.
Conclusion: Decide whether to accept or reject the hypothesis based on evidence.
Communication: Share findings and solicit critical feedback.

Technology

Definition: Practical implementation of knowledge in fields like industrial arts and manufacturing.
Technology Process: Encompasses identification, conceptualization, production, and application phases.

Development vs. Innovations

Innovations: Transform prototype inventions into commercially viable products.
Development: Converts research discoveries into new materials, devices, or processes.

Classification of Technology

First Wave Technology: Characterized by pre-industrial, labor-intensive practices.
Second Wave Technology: Features industrial, capital-intensive methods rooted in classical principles.
Third Wave Technology: Represents a post-industrial phase, reliant on contemporary scientific knowledge.

Society

Definition: A community of individuals living together with shared objectives.
Evolution of Societies: Societal development has progressed from hunter-gatherer groups to complex manufacturing and processing systems.
