Temperature progression in a mixer ball mill | SpringerLink

The kind of material influences the elasticity of the collision and the motion of the balls, as shown for planetary ball mills . Thus, it acts on the temperature progression and on the heat transfer from the balls to the wall of the beaker . Young´s modulus for example is insufficient to describe the increase of .

Overview effect - Wikipedia

The overview effect is a cognitive shift in awareness reported by some astronauts during spaceflight, often while viewing the Earth from outer space.. It is the experience of seeing firsthand the reality of the Earth in space, which is immediately understood to be a tiny, fragile ball of life, "hanging in the void", shielded and nourished by a paper-thin atmosphere.
