Abstract:
The paper “Direct observations of the viscosity of the outer core and extrapolation of measurements of the viscosity of liquid iron” by D. E. Smylie, V. V. Brazhkin, and A. Palmer (Usp. Fiz. Nauk179 91 (2009) [Phys. Usp.52 (1) (2009)]) is subject to critique for its proposed approach to estimating the viscosity of the Earth's outer core.
