Who cares about the history of science?
The Royal Society
Overview
This lecture explores the purpose and value of studying the history of science, moving beyond simplistic narratives of heroic discoveries. Professor Hok argues that history of science is not merely a collection of anecdotes but a vital tool for improving present scientific knowledge and practice. He distinguishes between 'orthodox' functions, which deepen understanding of current science, and 'complementary' functions, which involve recovering and extending knowledge where science itself falters. The talk emphasizes how historical inquiry can broaden conceptual horizons, reveal the contingency of scientific truths, and even generate new scientific insights by examining neglected or discarded ideas and experiments.

Chapters
- Many people, including scientists, question the practical utility of studying the history of science.
- Popular accounts often present myths or oversimplified stories of scientific discovery, like Newton and the apple.
- These simplistic narratives, while sometimes inspiring, obscure the complex realities of scientific progress.
- The core question is: what is the real purpose and benefit of engaging with the history of science beyond mere storytelling?
Understanding the common skepticism helps frame the subsequent arguments for why history of science is essential and not just an academic indulgence.
The myth of Newton discovering gravity from a falling apple, contrasted with the more complex reality of his work.
- Historians must avoid 'presentism' – judging the past solely by present-day standards and concerns.
- Herbert Butterfield advised seeing the past through the eyes of its own time to achieve true historical understanding.
- However, historians are inevitably situated in the present, and history writing serves the living.
- The purpose of historical understanding must be grounded in its relevance to our present situation and future.
This chapter highlights the challenge of historical interpretation and sets the stage for arguing that history of science must have a purpose for the present, not just for understanding the past accurately.
Herbert Butterfield's warning against 'the study of the past with one eye upon the present' as a source of historical error.
- History of science can serve 'internal' functions, directly benefiting present scientific knowledge and practice.
- Orthodox functions include providing a deeper, more nuanced understanding of accepted scientific concepts and their justifications.
- Studying the history of science can also illuminate the scientific method itself, which is often poorly understood by practicing scientists.
- Historical perspective helps non-specialists grasp scientific methods by examining simpler historical contexts.
These functions demonstrate how history of science can directly contribute to the quality and understanding of contemporary science, rather than being a separate, irrelevant discipline.
Understanding Newton's achievement not just as discovering gravity, but formulating it mathematically and linking it to alchemy and theology.
- Complementary functions go beyond understanding to actively generating new scientific knowledge where current science fails.
- History opens minds to new possibilities by revealing that current 'truths' were once contingent decisions.
- It expands conceptual horizons by showing that past science, though strange, was once rational and can inspire new ideas.
- History allows for the recovery of lost scientific knowledge and phenomena that were valid within their own contexts.
This is the most provocative claim: history of science can be a source of novel scientific discovery and a critical tool for challenging scientific limitations.
James Cushing's work showing how the Copenhagen interpretation of quantum mechanics became orthodoxy due to historical contingencies, not just scientific merit.
- Replicating historical experiments is a powerful way to recover and appreciate lost scientific knowledge.
- Examples include experiments on the radiation of 'caloric' (heat) and early electrochemistry.
- These experiments, though seemingly simple or outdated, can reveal phenomena and concepts overlooked by modern science.
- Such work can lead to new questions and further experimental investigation, extending knowledge.
Demonstrates concretely how engaging with historical scientific practice can yield tangible, new insights and stimulate further scientific inquiry.
The speaker's replication of experiments showing variations in water boiling points based on vessel material and heating rate, and Wollaston's experiment on electricity generation.
- Recovered historical experiments often raise new questions that current science doesn't address.
- This 'extension' of neglected knowledge can lead to novel scientific investigations.
- The speaker's experiments with electrochemistry in salt solutions, for instance, led to unexpected observations about electron behavior.
- These investigations highlight areas where specialized science might overlook fundamental questions.
This function emphasizes the dynamic and ongoing nature of scientific discovery, suggesting that the past holds untapped potential for future scientific progress.
Investigating why silver continued to grow in Sylvester's experiment after the copper was coated, and the unexpected gas production in salt solutions with inert electrodes.
- The internal and external functions of history of science are interconnected, forming a continuum.
- Understanding history helps us use and support science more wisely, addressing its social and economic impacts.
- History of science provides critical awareness to correct harmful scientific developments or applications.
- Studying the history of science is crucial for science education, teaching not just facts but the nature and methods of scientific inquiry.
Connects the academic study of history of science to its broader societal relevance, including policy, ethics, and educating future generations.
James Bryant Conant's post-WWII Harvard program to teach science to non-majors through historical case studies.
Key takeaways
- The history of science is more than just stories; it's a critical tool for improving current scientific understanding and practice.
- Avoiding 'presentism' is crucial for accurate historical interpretation, but history must ultimately serve the present and future.
- Studying the history of science can deepen our understanding of established scientific concepts and the scientific method itself.
- History of science can actively generate new scientific knowledge by recovering and extending neglected or discarded ideas and experiments.
- Replicating historical experiments is a valuable method for uncovering lost knowledge and stimulating new research questions.
- The study of history of science fosters critical awareness regarding science's societal impact, applications, and ethical considerations.
- Historical approaches to science education are vital for teaching the nature of science, not just its current findings, to both future scientists and the general public.
