Definition of Science and Technology

Science

  • Origin of the word from Latin "scientia," meaning knowledge.

  • A systematic method involving observation, experimentation, and reasoning.

Technology

  • Derived from the Greek "techne" (art/skill) and "logia" (study).

  • Application of scientific knowledge to create tools, systems, and solutions.

  • Example: The Lycurgus Cup (Roman Empire, 4th Century CE)

    • Changes color based on light angles, an early example of nanotechnology.

Ways Science is Viewed

  1. As an Idea: Theories and explanations about natural phenomena.

  2. As an Intellectual Activity: Systematic study and experimentation.

  3. As a Body of Knowledge: Organized discipline of scientific understanding.

  4. As a Personal/Social Activity: Tools for real-world problem-solving and improving life.

Antecendents

  • comes from the latin word “antecedens” meaning going before or precedinging.

  • refers to earlier discoveries

  • Example: The Atomic Theory

Key Scientific Concepts

Hypothesis

  • An educated guess formulated as an "if-then" statement.

  • Tested with data to be accepted or rejected.

Theory

  • A well-substantiated explanation from repeated observations.

  • Example: The Theory of Evolution explains species changes through natural selection.
