Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

In a study published in Physics of Fluids, the researchers used the Navier-Stokes equations—the bedrock math of fluid flows—and a few experiments to investigate the behavior of thin liquid films that ...

"This is among NASA's largest and most complex experiments for fluid physics research," Mudawar said. "We have published more than 70 papers on reduced gravity and fluid flow since the project's ...
