In this talk, Zhao’s random walk crossing the borders of experimental physics, applied math, engineering, and art will be sampled. Why striking the top of a beer bottle with a bare hand can shatter the bottom? Our high-speed imaging finds that small cavitation bubbles cause series damage. Why does a dog lift one of its hind legs when peeing against a tree? We found that this is a smart practice that can reduce urine splash back and inspired by dogs, we designed splash-free urinals for humans. Last, we introduce a unique uncertainty quantification technique based on the well-posed analysis of partial differential equations. This technique is suited for non-invasive pressure field estimation based on velocity measurement from MRI, ultrasound, and Particle Image Velocimetry (PIV) in experimental fluid mechanics.
