Have you ever done the cup-in-hand walk, and spilled your drink? It's a common event. The Krechetnikov Fluid Physics Lab at the University of California Santa Barbara usually doesn't focus on this type of problem, but after seeing enough people spilling, they decided to look into it!
Few physics experiments come with greater consequences than those done by a police crash reconstruction team.
From the acidic digestive fluid in your stomach to the dry, cratered surface of Mars, rockets could soon make it possible to explore extreme environments as never before.
Spring has sprung and the batters have swung. Baseball season has officially started. Although the games we watch in the big leagues could be drastically different by changing only one aspect; the bat.
Flying kites and tumbling plastic bags show that wind carries kinetic energy. The purpose of a windmill is to harness that energy. From the earliest versions 2,200 years ago in Persia to the Megawatt turbines today, windmills use physics to harness nature's chaotic fiery for human benefit.
San Francisco and Los Angeles, home to about 7.5 million people and to much of the economy of California, lie close to the infamous San Andreas fault.
In 1665, Isaac Newton recognized that all matter attracts all other matter, but he also recognized that the gravitational attraction of everyday objects for each other was far too small to be measured in his time.
After crossing Florida, Hurricane Katrina headed into the Gulf of Mexico early on August 26, 2005 as a Category One hurricane.
In our everyday world, matter is usually classified into solids, liquids, and gases. But what about dry sand?
