Reason, observation, and experience; the holy trinity of science.

Summary

This quote highlights the fundamental pillars of scientific inquiry: reason, observation, and experience. Reason refers to the logical and critical thinking required to formulate hypotheses and make deductions. Observation involves gathering empirical evidence through careful scrutiny of the natural world or laboratory experiments. Experience involves learning from past discoveries and applying accumulated knowledge. Together, these three elements constitute the "holy trinity" of science, as they guide scientists in the pursuit of knowledge and understanding of the world around us.
