In Praise of “Normal” Engineers

Cars That Think

A version of this post originally appeared in Refactoring , a Substack offering advice for software engineers. I think their existence is what explains the curious durability of the notion of a 10x engineer, someone who is 10 times as productive or skilled as their peers. At one point, I was a pretty good database reliability engineer.

ORNL team performs first neutron diffraction experiments on a running engine

Green Car Congress

Researchers at Oak Ridge National Laboratory (ORNL) have used neutron diffraction to provide noninvasive measurement of lattice strains inside components of a firing engine, thereby enabling the operando study of complex load states and thermal gradients throughout the solid materials. Camera lies along orthogonal 45° plane. Wissink et al.
