One way to reduce the damage caused by avalanches in the mountains is to place obstacles in their path. These obstacles can be artificial barriers or natural forests. Knowing how the avalanche interacts with obstacles is ...
(Phys.org) —Results from a microgravity experiment suggest that the rubble and dust covering asteroids and comets can feel changes in force-chains between particles over much larger distances than on Earth, making these ...
