They built this with substandard parts. No wonder it collapsed.

People joined the bumptious fray early and dynamically, even before they/we were critters who were later named Homo sapiens. But I think the issues about naming relevant to the Anthropocene, Plantationocene, or Capitalocene have to do with scale, rate/speed, synchronicity, and complexity.

How flourishes the King of Clubs? I always observe its mensiversary in my fancy.

There are actually three sweet spots on a racquet's face. Each sweet spot measures a different physical characteristic of your racquet. The sweet spot that most of us think of is the place on the strings where the ball rebounds with the most power, or, technically, the post on the racquet with the maximum coefficient of restitution. The second sweet spot is where the least amount of shock is given to your hand and arm. This is known as the center of percussion. The third sweet spot is the node or place where the least amount of vibration occurs after the initial ball impact. Normally all three sweet spots do not occur in the same location.
