    Study Notes

    Galileo's Pendulum Experiment

    • Galileo used heartbeats to measure the period of pendulums.
    • The period of a pendulum is directly proportional to the square root of its length.
    • Doubling the length of a pendulum, increases the period by a factor of the square root of 2, which is approximately 1.414.

    Deductive Reasoning

    • Deductive reasoning is a logical process of reaching a conclusion by applying general assumptions, procedures, or principles.

    Polya's Problem Solving Strategies

    • Polya suggests four problem-solving steps: Understand the problem, devise a plan, carry out the plan, review the solution.
    • To understand the problem, you need to clarify information, identify missing information, and define the goal.
    • Developing a plan includes making a list of known and needed information, drawing a diagram, or looking for patterns.
    • Carefully execute the plan and keep accurate records.
    • Reviewing the solution involves verifying its consistency with the problem, interpreting the solution, and considering potential generalizations.

    Problem Solving with Patterns

    • A sequence is an ordered list of numbers, each number is called a term.
    • The first term is the first number in a sequence, the second term is the second number, and so on.
