(*) viscosity and is called his drag.
This scientist co-names a device that measures sunlight intensity using a glass sphere to focus the light to burn a card; he names that "recorder" with Campbell. This scientist and an alphabetically prior man co-name an equation derived from Chapman–Enskog expansion of the Boltzmann equation. A quantity named for this scientist is set equal to the sum of the gravitational and electrostatic forces to determine the fundamental charge in the Millikan oil drop experiment; that quantity equals 6 pi r v times (*) viscosity and is called his drag. This scientist is the alphabetically latter namesake of an equation whose viscous term can be ignored in favor of the inertia term at low Reynolds number. For 10 points, name this physicist who co-names the central equation of fluid dynamics with Navier.
