About John F. Lindner

John F. Lindner was born in Sleepy Hollow, New York, and educated at the University of Vermont and Caltech. He is an emeritus professor of physics and astronomy at The College of Wooster and a visiting professor at North Carolina State University. He has enjoyed multiple yearlong sabbaticals at Georgia Tech, University of Portland, University of Hawai'i, and NCSU. His research interests include nonlinear dynamics, celestial mechanics, and neural networks.

Chemical Wires

With undergraduates Mahala Wanner and Gus Thomas, Niklas Manz and I recently published an article Chemical wires: reaction-diffusion waves as analogues of electron drift in the journal Transport Phenomena. We used chemical reaction-diffusion waves in n… Continue reading

e is Transcendental

Introduction The Euler-Napier-Bernoulli constant [latex]e =2.7182\ldots [/latex] is not just irrational, it is transcendental, as first proved by Charles Hermite in 1873. Inspired by the work of Mathologer (Burkard Polster with Marty Ross), here I offe… Continue reading

My First Patent

In last month’s blog post, I described my second patent, which raises the question, What was my first patent? In 1998, my colleagues and I were issued United States Patent No. US 5 789 961  “Nose- and coupling-tuned signal processor &#… Continue reading

My Second Patent

Today, about six years after beginning the relevant research, my colleagues (and fellow inventors) and I have been issued U.S. Patent No. US 12,450,468 B2, “Physics augmented neural networks configured for operating in environments that mix order… Continue reading

Extreme SI Prefixes

In the spring of 2020, on my NC State sabbatical, during the initial lock-down for the worst pandemic of my lifetime, I stayed busy in part by writing a text called g = 2: A Gentle Introduction to Relativistic Quantum Mechanics. … Continue r… Continue reading

Wooster Physicists

I recently discovered that the College’s yearbooks, The Index, are now online, and I spent several days extracting some physics history, supplemented by the Alumni Catalogue 1870-1925 and several Annual Catalogues, also online, as well as the Physics D… Continue reading

Nimble Neural Networks

Artificial neural networks are increasingly important in society, technology, and science, and they are increasingly large and energy hungry. Indeed, the escalating energy footprint of large-scale computing is a growing economic and societal burden. Mu… Continue reading

Logic with Nonlinear Maps

In 1999, Bryan Prusha ’98 and I wrote an article for Physics Letters A illustrating why logic requires nonlinearity. Recently, with Bill Ditto, I revisited this theme by demonstrating how to encode all 16 binary boolean (true-false) functions in … Continue reading

Barred Warped Wobbly Spiral

Advances in astronomy can rewrite even introductory astronomy textbooks. Although no spacecraft have yet exited our Milky Way galaxy to image it from the outside, the Gaia astrometry space telescope recently completed a dozen years of accurately measur… Continue reading

Weak Prime Number Theorem

As a child, I was inspired by Arthur C. Clarke‘s 1956 science fiction novel The City and the Stars to search for patterns in prime numbers. Chapter 6 begins: Jeserac sat motionless within a whirlpool of numbers. The first thousand … Continu… Continue reading
