This promotional video for NOMOS Glashütte is delicate, detailed, quiet, and fascinating. Master craftspeople assemble the mechanical timepiece’s gears, hands, and other tiny parts with precision as we Look Over the Watchmakers’ Shoulders.
From the BBC’s Ocean Giants documentary, watch this incredible clip to hear the extraordinary and mysterious song of the Humpback Whale. Why do they sing (or hum)? Does it serve a purpose? Are they making music for pleasure? Are they talking?
When light travels through areas of different air density, it bends. You’ve probably noticed the way distant pavement seems to shimmer on a hot day, or the way stars appear to twinkle. You’re seeing light that has been distorted as it passes through varying air densities, which are in turn created by varying temperatures and pressures.
Schlieren Flow Visualization can be used to visually capture these changes in density: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze … even sound.
