Study Notes
General Knowledge: Science
Fundamental Concepts
- Scientific Method: A systematic approach to inquiry involving observation, hypothesis formulation, experimentation, and conclusion.
- Hypothesis: A testable prediction based on observations.
-
Theory vs. Law:
- Theory: A well-substantiated explanation of an aspect of the natural world.
- Law: A statement that describes an observable phenomenon.
Major Branches of Science
-
Physical Science:
- Focuses on non-living systems.
- Includes physics (study of matter and energy) and chemistry (study of substances and their interactions).
-
Life Science (Biological Science):
- Focuses on living organisms and life processes.
- Includes biology (study of life), ecology (study of interactions between organisms and their environment), and genetics (study of heredity and variation).
-
Earth Science:
- Study of Earth and its components.
- Includes geology (study of the Earth’s solid materials), meteorology (study of the atmosphere and weather), and oceanography (study of oceans).
-
Formal Science:
- Deals with formal systems and logical reasoning.
- Includes mathematics, statistics, and computer science.
Key Scientific Principles
- Energy Conservation: Energy cannot be created or destroyed, only transformed.
- Cell Theory: All living organisms are composed of cells; the cell is the basic unit of life.
- Evolution: The process through which species change over time through natural selection and genetic variation.
Notable Scientists
- Albert Einstein: Developed the theory of relativity, revolutionizing physics.
- Marie Curie: Pioneered research on radioactivity, first woman to win a Nobel Prize.
- Charles Darwin: Formulated the theory of evolution by natural selection.
Important Scientific Tools
- Microscope: Allows for the observation of small objects and organisms.
- Telescope: Used for observing distant celestial objects.
- Spectrometer: Analyzes the spectrum of light to determine properties of substances.
Recent Advancements
