Why am I passionate about this?

I have taught undergraduate and PhD students physics and biophysics for 36 years, and I never get tired of it. I always look for hot new topics and everyday things that we all see but rarely notice as interesting. I also look for “how could anything like that possibly happen at all?”-type questions and the eureka moment when some idea from physics or math pries off the lid, making a seemingly insoluble problem easy. Finally, I look for the skills and frameworks that will open the most doors to students in their future work.

The books I picked & why

Book cover of So Simple a Beginning: How Four Physical Principles Shape Our Living World

Philip Nelson Why did I love this book?

Elegant, deep—I learned many things here. 

This book will help you develop your own good ideas because the author respects you too much to give a jumble of just-so stories wrapped in glib human interest. Instead, he explains, often with brilliant metaphors from everyday experience. I especially liked the chapters on embryos, organs, the microbiome, and scaling, which are particularly fresh, insightful, and beautifully clear.

Also, unlike so many popularizations, this one is full of graceful but precise illustrations that pull you in and actually clarify key points—not just eye candy. This book will help you have your own ideas by interconnecting physics and biology ideas that are hardly ever mentioned in the same breath.

What is this book about?

A biophysicist reveals the hidden unity behind nature's breathtaking complexity

The form and function of a sprinting cheetah are quite unlike those of a rooted tree. A human being is very different from a bacterium or a zebra. The living world is a realm of dazzling variety, yet a shared set of physical principles shapes the forms and behaviors of every creature in it. So Simple a Beginning shows how the emerging new science of biophysics is transforming our understanding of life on Earth and enabling potentially lifesaving but controversial technologies such as gene editing, artificial organ growth, and ecosystem…


Book cover of Shape: The Hidden Geometry of Information, Biology, Strategy, Democracy, and Everything Else

Philip Nelson Why did I love this book?

A readable, yet profound tour of what math is really all about.

This book will help you have your own ideas because it opens your eyes to mathematical themes that go to the heart of things you care about yet may never have thought of as mathematical. For me, the analysis of gerrymandering was a sobering prime example.

An instant New York Times Bestseller!

“Unreasonably entertaining . . . reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning.” —The New York Times  

From the New York Times-bestselling author of How Not to Be Wrong—himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything.

Book cover of The Joy of X: A Guided Tour of Math, from One to Infinity

Philip Nelson Why did I love this book?

Math is so much more than algebra.

Steve Strogatz is our generation’s poet laureate of math. I could not put this book down because, although I use math daily, I was amazed at how Strogatz connects everything to everyday experience. Just one example: Hardly anyone gets told about “group theory” in high school because it’s “too advanced”—but here we find it beautifully illustrated with the problem of flipping your mattress twice a year.

This book will help you have your own ideas by opening your eyes to a world of things that just make better sense through the lens of careful analysis, the interplay of the visual and the symbolic, and (just enough) abstraction.

What is this book about?

Award-winning Steven Strogatz, one of the foremost popularisers of maths, has written a witty and fascinating account of maths' most compelling ideas and how, so often, they are an integral part of everyday life.

Maths is everywhere, often where we don't even realise. Award-winning professor Steven Strogatz acts as our guide as he takes us on a tour of numbers that - unbeknownst to the unitiated - connect pop culture, literature, art, philosophy, current affairs, business and even every day life. In The Joy of X, Strogatz explains the great ideas of maths - from negative numbers to calculus, fat…


Book cover of QED: The Strange Theory of Light and Matter

Philip Nelson Why did I love this book?

Blew my world apart. 

Without one single formula, Feynman takes you to the heart of quantum theory. The foundations of everything you thought you knew about light get ripped out and replaced by new foundations that cover every success of the 19th-century theory yet offer new vistas. I will probably read this tiny book every year for the rest of my life; each time I get new insights into physics (and the presentation of physics).

After reading it, you will understand the stationary-phase principle better than most Physics PhD students without one formula.

4 authors picked QED as one of their favorite books, and they share why you should read it.

What is this book about?

Celebrated for his brilliantly quirky insights into the physical world, Nobel laureate Richard Feynman also possessed an extraordinary talent for explaining difficult concepts to the general public. Here Feynman provides a classic and definitive introduction to QED (namely, quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles. Using everyday language, spatial concepts, visualizations, and his renowned "Feynman diagrams" instead of advanced mathematics, Feynman clearly and humorously communicates both the substance and spirit of QED to the layperson. A. Zee's introduction places Feynman's book and his seminal contribution to QED in historical context and…


Book cover of The Drunkard's Walk: How Randomness Rules Our Lives

Philip Nelson Why did I love this book?

A thread that ties together so many things.

Throughout science, math, finance, and your personal life… underlying almost everything is the concept of a random walk. I love how Mlodinow builds our intuition for this simple yet subtle idea. Yes, the expectation may be zero, but the variance grows without limit—it took me years of study to truly feel that statement and others in my bones, but Mlodinow shows this and much more through vivid, often hilarious examples. It is no exaggeration to say that after Chapter 6, you will understand conditional probability—where so many of us stumble when we think about real situations—better than you would after a whole course on statistics.

And although this is a science book, I challenge anyone to read the last five pages and end up dry-eyed. Years later, as I reread them, the impact is undiminished.

What is this book about?

Leonard Mlodinow's The Drunkard's Walk: How Randomness Rules Our Lives is an exhilarating, eye-opening guide to understanding our random world.

Randomness and uncertainty surround everything we do. So why are we so bad at understanding them?

The same tools that help us understand the random paths of molecules can be applied to the randomness that governs so many aspects of our everyday lives, from winning the lottery to road safety, and reveals the truth about the success of sporting heroes and film stars, and even how to make sense of a blood test.

The Drunkard's Walk reveals the psychological illusions…

Biological Physics Student Edition: Energy, Information, Life

By Philip Nelson,

Book cover of Biological Physics Student Edition: Energy, Information, Life

What is my book about?

My book focuses on results in molecular motors, self-assembly, and single-molecule manipulation that have revolutionized the field in recent years, integrating with classic results. It also provides foundational material for the emerging fields of nanotechnology and mechanobiology. Instead of offering a huge pile of facts, the discovery-style exposition frequently asks the reader to reflect on "How could anything like that possibly happen at all?" Working through this book will give you an appreciation for how science has advanced.

Additional topics include the physics of diffusion, bacterial motility, self-assembly, entropic forces, enzyme kinetics, ion channels, and pumps, the chemiosmotic mechanism and its role in ATP maintenance, and the discovery of the mechanism of neural signaling.
