The Scientific Method. The loop that built the modern world.

Question, hypothesis, experiment, observation, conclusion. Then repeat. It is not a one-time path. It is a loop. Every piece of technology you use today exists because someone ran this cycle enough times. The method does not give answers. It gives a way to test whether an answer is right.

• A hypothesis is not a guess. It is a testable statement. "I think it will rain" is a guess. "If humidity exceeds 80%, rain will fall within 6 hours" is a hypothesis.
• Science does not prove things true. It rules things out until what remains is the best explanation so far.
