Shaking a physical system typically heats it up, in the sense that the system continuously absorbs energy. When considering a circular shaking pattern, the amount of energy that is absorbed can potentially depend on the orientation ...

Roughness, the presence of irregularities on a surface, is commonly associated with slower motion and stickiness. This is true at different length scales: at human size (1 meter), it takes longer to walk along a path that ...

Normally, causal influence is assumed to go only one way—from cause to effect—and never back from the effect to the cause—the ringing of a bell does not cause the pressing of the button that triggered it. Now, researchers ...

Feeling empathy for others is deeply engrained into our biology, as seeing another individual in pain triggers an empathic response in the brain of the observer, which allows us to understand and feel what other feels. However, ...
