Biography
John does research in fluid mechanics and its applications, especially on the movement of drops and bubbles, especially if their surfaces are contaminated. He used to teach fluid mechanics, calculus, complex analysis, and related topics.
- Corrections to "The motion of bubbles and drops through liquids" (1972)
- The Coulomb potential of a line of charges (1993)
- Reducing Parabolic Partial Differential Equations to Canonical Form (1994)
- Paleomagnetism (1995)
- Plate Tectonics (1995)
- Bubbles rising in a line: why is the first approximation so bad? (1997)
- The axisymmetric Prandtl-Batchelor eddy behind a circular disc in a uniform stream (1998)
- A bubble rising in viscous fluid: Lagrange's equations for motion at a high Reynolds number (2001)
- Growing bubbles rising in line (2001)
- Stagnant-cap bubbles with both diffusion and adsorption rate-determining (2004)
- Fortran 95 for Fortran 77 users (revised 2007)
- What really is a continuous function? (2007)
- Bubble rise in a liquid with a surfactant gas, in particular carbon dioxide (2007)
- Bubbles rising in line: champagne, lager, cider (2008)
- New diatom taxa from the world's first marine Bioblitz held in New Zealand: Skeletomastus a new genus, Skeletomastus coelatus nov. comb. and Pleurosigma inscriptura a new species (2009)
- Otari and Taputerangi Bioblitzes: diatoms - microscopic algae (2010)
- Electrophoresis of surfactant-free bubbles (2010)
