Introduction to Science

• Science employs a systematic and organized methodology to comprehend the natural world through observation, experimentation, and analysis.
• It is composed of a diverse array of disciplines, each dedicated to examining distinct facets of the universe.
• The scientific method serves as a fundamental element in scientific investigation.

Scientific Method

• Observation involves a scientist beginning with observing phenomena in the natural world.
• Hypothesis involves formulating a testable explanation to explain observations.
• Experimentation involves designing and conducting experiments to test the hypothesis.
• Analysis involves the data collected being analyzed to see whether it supports or refutes the hypothesis.
• Conclusion involves drawing conclusions based on analysis, the hypothesis may be revised or refined.

Branches of Science

• Natural Sciences focus on the physical world and include fields like physics, chemistry, biology, and earth science.
• Social Sciences study human society and behavior, including disciplines like psychology, sociology, economics, and political science.
• Formal Sciences involve abstract systems and logic, such as mathematics, computer science, and statistics.
• Applied Sciences apply scientific knowledge to practical problems and technological advancements, including engineering, medicine, and agriculture.

Physics

• The study of matter, energy, and their interactions.
• Classical Mechanics deals with the motion of macroscopic objects under the influence of forces.
• Thermodynamics studies the relationships between heat, work, and energy.
• Electromagnetism investigates the interaction between electric and magnetic fields.
• Quantum Mechanics explores the behavior of matter and energy at the atomic and subatomic levels.
• Relativity encompasses Einstein's theories of special and general relativity, which describe the relationship between space, time, gravity, and the universe.

Chemistry

• The study of matter, its properties, composition, structure, and how it changes.
• Organic Chemistry focuses on compounds containing carbon, primarily found in living organisms.
• Inorganic Chemistry deals with compounds that do not contain carbon, including metals, minerals, and other non-organic substances.
• Physical Chemistry applies physics principles to study chemical systems, including thermodynamics, kinetics, and quantum chemistry.
• Analytical Chemistry involves the identification and quantification of substances.
• Biochemistry explores the chemical processes within living organisms.

Biology

• The study of living organisms, their structure, function, growth, origin, evolution, and distribution.
• Cell Biology studies the structure and function of cells, the basic units of life.
• Genetics investigates heredity and the variation of inherited characteristics.
• Ecology focuses on the interactions between organisms and their environment.
• Evolution studies the processes by which populations of organisms change over time.
• Microbiology examines microorganisms, such as bacteria, viruses, and fungi.
• Botany is the scientific study of plants.
• Zoology is the scientific study of animals.

Earth Science

• The study of Earth, its structure, composition, processes, and history.
• Geology studies the Earth's solid materials, structures, and processes.
• Meteorology focuses on the atmosphere and weather patterns.
• Oceanography explores the oceans, including their physical, chemical, and biological aspects.
• Environmental Science examines the interactions between humans and the environment.
• Paleontology studies prehistoric life through the examination of fossils.

Social Sciences

• Psychology is the scientific study of the human mind and its functions, especially those affecting behavior in a given context.
• Sociology is the study of the development, structure, and functioning of human society.
• Economics is the study of how societies allocate scarce resources to satisfy unlimited wants.
• Political Science is the study of the theory and practice of politics and the description and analysis of political systems and political behavior.
• Anthropology is the study of human societies and cultures and their development.

Formal Sciences

• Mathematics is the abstract science of number, quantity, and space; it may be used in its own right (pure mathematics), or as applied to other disciplines such as physics and engineering (applied mathematics).
• Computer Science is the study of the principles and use of computers.
• Statistics is the practice or science of collecting and analyzing numerical data in large quantities, especially for the purpose of inferring proportions in a whole from those in a representative sample.

Applied Sciences

• Engineering is the branch of science and technology concerned with the design, building, and use of engines, machines, and structures.
• Medicine is the science or practice of the diagnosis, treatment, and prevention of disease.
• Agriculture is the science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products.

Scientific Theories and Laws

• Scientific Theory: A well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experimentation.
• Scientific Law: A statement that describes an observed regularity or relationship in nature.
• Theories explain why something happens, while laws describe what happens.

Technology and Innovation

• Science drives technological advancements by providing the foundational knowledge upon which new technologies are built.
• Innovation involves the application of scientific knowledge to create new products, processes, and services.
• Technological advancements often lead to new scientific discoveries by providing scientists with new tools and techniques for exploration.
