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.
