Notes & Reactions

• “Normal science” is the day-to-day puzzle-solving that happens inside an accepted paradigm — and most science is this, not revolution.
• A paradigm doesn’t fall because it’s disproven; it falls when a better one is available to replace it. Anomalies pile up first.
• The “invisibility of revolutions” chapter is the sneaky one: textbooks get rewritten after a shift, so the discontinuity disappears from the record.

Quotes

The transfer of allegiance from paradigm to paradigm is a conversion experience that cannot be forced.

Normal science does not aim at novelties of fact or theory and, when successful, finds none.

Bibliography / Sources

Works this book is in conversation with (linked where I have my own notes):

• Fleck, Ludwik. Genesis and Development of a Scientific Fact (1935) — Kuhn credits this as a forerunner.
• Popper, Karl. The Logic of Scientific Discovery (1959) — the falsificationist view Kuhn argues against.
• Polanyi, Michael. Personal Knowledge (1958) — on tacit knowledge in scientific practice.
