Of a slate dominated by exam-cram shorts, hashtag spam, and a glossy powerpack marketing reel, this PEwise session is the only candidate that actually teaches a real engineering concept from first principles. The video walks through a conceptual problem on liquefaction-induced lateral spreading — one of the more counterintuitive failure modes in geotechnical engineering, where loose, saturated granular soil temporarily loses its shear strength under cyclic seismic loading and flows downslope, often dragging foundations, pipelines, and bridge abutments with it.

The framing is a "PE Power Hour" — meaning it's aimed at engineers preparing for the Principles and Practice of Engineering (Geotechnical) exam — but the diagnostic reasoning is broadly useful. To get the answer you have to reason about pore pressure buildup, free-face geometry, ground slope, soil density (relative density / SPT N-values), and the duration of shaking, then map those into the empirical frameworks (Youd, Hansen, Bartlett) practitioners actually use.

It's a small channel (16 subs) by a working PE, which usually translates to no-nonsense whiteboard pacing and correct units — exactly what you want when the topic is this technical. Even if you're not sitting for the exam, watching someone diagnose a liquefaction case rather than just define it is a good way to build engineering intuition for post-earthquake site investigation.
