    Study Notes

    Introduction to Science and the Scientific Method

    • Science is a way of thinking and a method for acquiring knowledge
    • Science aims to understand the universe, from the subatomic to the cosmic realm
    • Science progresses through the accumulation of knowledge across various disciplines like physics, biology, psychology, and astronomy
    • The essence of science encompasses not just finding answers but also formulating questions to drive exploration and inquiry

    Nullius in Verba

    • Nullius in Verba, a motto of the Royal Society, translates to "on the word of no one"
    • This represents a commitment to verifying statements through experimentation and appeals to facts
    • It emphasizes critical thinking and a rejection of accepting authority without independent verification

    Objectives of Science Study

    • Articulate the methods and content of science
    • Describe the objectives of basic and applied science
    • Compare inductive and deductive reasoning
    • Demonstrate and apply scientific attributes

    Science as a Maxim

    • "Nullius in Verba" means trusting scientists' words, relying on rational thinking, doubting authority figures (pastors or priests), and questioning everything.

    Essence of Science

    • Science is more than equations or facts; it's a way of thinking and a process to acquire knowledge
    • Science explores the mysteries of the universe, from the atomic to the cosmos
    • Science is a dynamic process that evolves with accumulating knowledge
    • Science encompasses diverse disciplines, including physics, biology, psychology, and astronomy
    • Science values asking questions just as much as pursuing answers

    Chapter 1: The Essence of Science

    • The Latin word "scientia" gives us the term "science," meaning knowledge
    • The methodical understanding of the natural world, using observation, experimentation, hypothesis testing, and evidence-based conclusions, emerged during the Renaissance and Enlightenment
    • Science's impact on society has grown significantly, propelled by technological advancements.

    Chapter 2: The Nature of Science

    • Science is a method of studying the natural world through observation, experimentation, and exploration
    • Science involves: empirical (based on observation), objective (unbiased), non-dogmatic (not unquestionable), self-correcting(open to change), systematic(organized), and transparent (open to scrutiny) approaches

    Transparent and Open to Critique

    • Scientific knowledge is disseminated through peer review and publication where other scientists anonymously critique the work.
    • This process ensures that only good science gets published by weeding out invalid methods or incorrect conclusions.

    Attributes of Science

    • Objective, self-correcting, non-dogmatic, critical, and transparent are attributes of scientific practice

    1.2: The Process of Science

    • Basic Science: Focuses on advancing knowledge, regardless of direct application (e.g., cell biology, genetics).
    • Applied Science: Solves practical problems using scientific knowledge (e.g., medical technologies, agricultural advancements).

    1.3: Inductive vs Deductive Reasoning

    • Inductive Reasoning: Starts with specific observations, leading to generalizations about a broader concept.
    • Deductive Reasoning: Starts with a broad generalization, leading to specific conclusions

    Examples of Inductive and Deductive Reasoning

    • Inductive: Observing many swans to be white, and generalizing to say "all swans are white" .
    • Deductive: All men are mortal. Socrates is a man. Therefore, Socrates is mortal.

    The Scientific Method

    • A structured approach to investigating the natural world, involving questioning, researching, constructing a hypothesis, testing it via experimentation, analyzing data, and drawing conclusions.

    2.1 Steps of the Scientific Method

    • Observe or ask a question
    • Research the problem (e.g., gathering information, observing more closely)
    • Develop a hypothesis (a testable prediction)
    • Experimentation (testing the hypothesis)
    • Analyze data and draw conclusions
    • Communicate findings (e.g., publishing results, giving presentations).

    Variables in Experiments

    • Variables are factors that can change during an experiment
    • Independent variable: Manipulated; the factor you change or test.
    • Dependent variable: Measured; the factor affected by the independent variable.
    • Controlled variables: Remain constant; factors that are kept the same in all parts of the experiment

    Chapter 4: Current Challenges in Science and Society

    • Climate Change: A significant challenge, caused by greenhouse gas emissions, leading to rising temperatures and environmental problems.
    • Artificial Intelligence (AI): Rapidly advancing technology with potential benefits but also concerns about job displacement and weaponization
    • Genetic Engineering: Modifying genes has potential to cure diseases and improve food production, but raises concerns about designer babies and the impact on the environment
    • Inequality: Uneven distribution of scientific and technological benefits, affecting social equality
    • Misinformation and Fake News: The spread of incorrect or misleading science information compromises public trust and decision-making.
