Document Summary
How to measure progress in science: theory, hypothesis, test and gather evidence, empirical validation. Building a knowledge base: search for empirical regularities, find theoretical explanations, test explanations, accumulate laws. What to do when laws contradict each other: Intellectual honesty is key; admit that not all laws are perfect and infallible. Karl popper aggressive falsifiability be rigorously skeptical: weed out theories via testing only theories that continuously withstand falsification can be considered true adopt logic of null hypothesis.
