Amazingly Vivid Dino Illustrations Reveal a Brutal Prehistoric World
Over its lifetime, Earth has hosted countless species. But some of those species, like the dinosaurs, have managed to claw their way into a special place in our imaginations. Now, a new book illustrates the dinosaurs — and many of the beasts of millennia ago — in beautiful, spectacular and vicious style. In one illustration, tiny Utahraptors tear at the flesh of a much larger creature. Another shows a rather unlikely but fanciful encounter between giant megalodon and funny-looking platybelodon. A more serene image depicts a well-camouflaged little dinosaur sleeping beneath a tree in a lush, green forest.

What Does Sound Look Like?
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 as it passes through varying air densities, which are in turn created by varying temperatures and pressures.
In the mid-19th century, German physicist August Toepler invented a photography technique called Schlieren Flow Visualization to visually capture these changes in density. The setup is a bit hard to explain in words (watch the video above for a full explanation) but it allows scientists and engineers to see things that are normally invisible: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze.
