The Meandering Path

Pleural Fibroma; A meandering path to surgical removal

A 52 Year old male was admitted with respiratory distress. Radiological examination revealed a large mass in patient's right hemi thorax with mediastinal shift and partial lung collapse. Biopsies previously done conferred the diagnosis of solitary fibrous tumor; however, in order to avoid a surgical resection, patient didn't follow the adviced procedure. After thorough counseling, surgical rese...

Spiral Meandering

The complex, so called meandering, dynamics of spiral waves in excitable media is examined from the point of view of bifurcation theory. A computational bifurcation analysis is made of spiral dynamics. It is shown that spiral meandering is organized in parameter space around a codimension-two point where a Hopf bifurcation from rotating waves interacts with symmetries on the plane. A simple mod...

The statistical mechanics of meandering

2014 We present a simple mathematical model to describe the statistical properties of the meandering of narrow streams on clean and smooth substrates. The model is shown to contain three different regimes, depending on the flow rate : (i) at low rates, the stream path is a timeindependent random walk ; (ii) for intermediate flow rates, static meanders appear. The onset of meandering is found to...

Interdisciplinary Meandering in Science

I was a graduate student in mathematics at Princeton immediately following World War II, 1945–1947. In those days, with veterans of the war inundating universities, there was no option but to earn a Ph.D. within two years. My thesis research was in functional analysis, an area of abstract mathematics. My mentor was Professor S. Bochner, a distinguished contributor to harmonic analysis. My class...
