Questão de Língua Inglesa

What time is it? That simple question probably is asked more often today than ever. In our clock‐studded, cell‐phone society, the answer is never more than a glance away, and so we can blissfully partition our days into ever smaller increments for ever more tightly scheduled tasks, confident that we will always 5 know it is 7:03 P.M. Modern scientific revelations about time, however, make the question endlessly frustrating. If we seek a precise knowledge of the time, the elusive infinitesimal of “now” dissolves into a scattering flock of nanoseconds. Bound by the 10 speed of light and the velocity of nerve impulses, our perceptions of the present sketch the world as it was an instant ago—for all that our consciousness pretends otherwise, we can never catch up. Even in principle, perfect synchronicity escapes us. Relativity 15 dictates that, like a strange syrup, time flows slower on moving trains than in the stations and faster in the mountains than in the valleys. The time for our wristwatch or digital screen is not exactly the same as the time for our head. Our intuitions are deeply paradoxical. Time heals all 20 wounds, but it is also the great destroyer. Time is relative but also relentless. There is time for every purpose under heaven, but there is never enough. Scientific American, October 24, 2014. Adaptado.
