"When light passes between 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 it passes through varying air densities, which are in turn created by varying temperatures and pressures.
In the mid-nineteenth century, German physicist August Toepler invented a photography technique called Schlieren Flow Visualization to visually capture these changes in density."
