Breaking in a new vehicle is really about the engine. The break-in — or mechanical run-in — period is designed to begin to wear the engine evenly and smoothly with low, consistent pressure, normal operating temperature and smoothly flowing oil. The goal is to get the engine's piston rings, which expand, contract and flex, to seat properly on the cylinder walls. If there are imperfections in the pistons or the cylinder walls from the manufacturing process, working the engine too hard and too soon can wear down those imperfections too quickly. That leads to "hot spots" within the engine's cylinders, which can cause problems in the years to come. … [Read more...] about Do You Have to ‘Break In’ a New Car?

That's in part because in July 2017, a Japanese university announced the opening of the world's first international ninja research center. Mie University is located in Iga, in Mie Prefecture, about 40 miles (64 kilometers) southwest of Kyoto, where the first and most famous ninja "school" may have existed in the 16th century. The new research center will house not only historical documents related to the ninja, but also hundreds of novels, movies and cartoons that have helped to forge the modern image of the black-clad assassin. … [Read more...] about Research Center Seeks to Separate Ninja Fact From Fiction
It's a system that's been around since ancient times. "The idea of celestial coordinates does assume that the sky is a sphere that surrounds the Earth. This is the idea that traces back to the early belief that the Earth was the center of everything," Christopher Palma, a teaching professor and associate head for undergraduate programs in the Department of Astronomy and Physics at the Pennsylvania State University, says in an email. "Even though we now know that to not be true, it is still true that the sky appears to be a sphere surrounding us, so we can use spherical coordinates to identify any location on the sky." … [Read more...] about How Do We Find Things in the Blackness of Space?
