The best books for understanding what science and scientists are really all about

Though I have been a scientist for nearly all of my life, as a student and as a professional, not until I read this book did I understand what an amazing human activity science is. I had never imagined a world without the word or practice of “science” or even “scientist,” as I do now because of this captivating book.

Wootton’s book is more than a history of how humankind invented and developed one of its most powerful tools. It also reveals the many simply exquisite workings of that tool over the centuries. After pondering its many remarkable revelations, interconnections, and insights, even as a scientist, my appreciation of the significance of science and scientists in the world has re-blossomed.

When I was a biomedical science graduate student, this book was on my shelf for a couple of years before I read it. I had pulled it out of a classmate’s trash bag when I was helping him move. Later, when I became distressed because my research findings were dismissed as “controversial,” a postdoctoral fellow in my lab told me that what I experienced was actually quite normal for novel scientific findings and I should read this book.

I did, and it changed forever my understanding of science and how scientists often resist accepting from others the very thing they pursue themselves: new discoveries. When I became a principal scientist, I made a gift of this book to every new scientist graduating from my laboratory.

Once I finished reading Kuhn’s Structure of Scientific Revolutions, it wasn’t long before I learned that he had followed it up with a collection of deeper analyses in the realm of the philosophy of science.

His sequel book took me deeper into the minds and conflicts of noted greats of science whose scientific contributions’ acceptance is now taken for granted by most. Yet, in their own day, they, too, often had to contend with the tension of science’s and scientists’ history of preferring what consensus had ordained as settled knowledge instead of welcoming new insights and discoveries.

I don’t remember how this book made it into my hands, but I am so glad it did! This book has made me a better scientist because it taught me scientific humility. Popper rips apart the very fabric of experimental science’s unique and most powerful tool, the scientific method.

When I taught students at MIT how to apply experimental analysis with the scientific method to establish that an observed effect was, in fact, caused by an identified factor, always in my head, I would hear the words of Popper. Past relationships between factors and effects are not necessarily maintained in the future. This understanding of the nature of the universe reveals the imperfections of science, which rarely proves the world’s truths but often does elucidate them.

As a professor at MIT, I used this book to introduce undergraduates in my course in environmental science to the love of statistics. No doubt it is a fun read because students in disciplines like engineering, biology, physics, and mathematics actually read it! I decided to use it for my course because of its entertaining approach to introducing fundamental statistical concepts and methods as it develops the history of the discipline with amusing color commentary about the principal players who starred in it.

Without sound statistical analyses, experimental data are figments of scientists’ imagination. It is a must-read to enjoy how analysis of something as frivolous as whether a lady can tell if the milk or the tea were added first to a cup inspired one of the most powerful statistical methods.
