Visualizing our solar system is one of those third-eye treats that never grows old. The Sun and its gravitationally bound planets, asteroids, etc. are in constant relative motion, and thinking about ...
Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
Development of a relative velocity factor comparing inlet flow rates of gas pipeline tees can predict the maximum erosion position inside the tee. A simulation model combining the k-ε turbulent and ...
