The best clocks now scan a one-hertz-wide sweet spot to find its exact center, plus or minus one millihertz, in every single measurement—despite the Heisenberg limits.
For example, the Long Now Foundation has as its flagship project a mechanical clock that is designed to still be marking time thousands of years hence.
To draw attention to what they see as the time pressure on the issue, campaigners led by Danish artist Olafur Eliasson, have installed twelve mini-icebergs in the shape of a clock in the Place de la Pantheon.
为吸引关注给气候变化问题施加时间压力,由丹麦艺术家埃利亚松领导的活动者在 Place de la Pantheon安置了十二座时钟形小冰山。
