Whenever I asked my late father-in-law about what he wanted for his birthday, he would always ask for a “time stretcher.” He wanted to have even one more second of life to enjoy and treasure. He also wanted even one more second to get things done. So, he hoped to stretch time.
Well, today is leap-second day. An extra second is added just before midnight. What will you do with your extra second?
Leap seconds were not needed for most of humanity. We could not tell that the Earth’s spin had been slowing down until we had something more precise than an astronomical clock. It probably wasn’t even important until we had really precise atomic clocks. Now, these clocks are out of sync with our astronomical clock. Hence, we add a second.
Does anyone care? CNET says that we should consider the camera developed by MIT researchers that is so fast it can actually capture a trillion frames per second, allowing scientists to track the movement of actual photons. We have to account for it.
What does it matter to you? Well, my father-in-law would have cherished his extra second.
