SUMMERTIME IS SHORTER TIME THAN YOU THINK IT IS

 

Summertime: there's never enough summer and never enough time. Everyone rushes; to the stores, to the ferry. Lines are long, flip flops are sweaty, kids are rude. Nostalgia rises up slowly from the porch, it greets you like an old hound in hot sun. It remembers slower times, fewer crowds, and lost smiling gentle folks, who were polite.

Today's pressure is not entirely imaginary. To be on time today, you have to be early. Even the ferry leaves early and if you don't want to miss it, you'd better arrive early. The ferry leaves at least 5.74 microseconds early, to be exact.

You can blame all this change on the fact that days aren't what they used to be. Because of recent earthquakes, days are shorter. There's less time in each day. I am not kidding.

As explained by Dr. Richard Gross, at NASA's JPL (Jet Propulsion Laboratory), recent quakes made our planet spin faster. The percentage of sunlight and darkness every day doesn't change but our days are shorter.

In 2004, we lost 2.68 microseconds because of the undersea tsunami. In 2010, we lost 1.26 microseconds because of the earthquake in Chile In March of 2011, we lost 1.8 microseconds because of the Japan Tohoku earthquake and tsunami. All this adds up.

A GPS station located directly in the epicenter of the Japan quake proved that Earth's splitting widened Japan by thirteen feet (13 feet). A group of JPL scientists, investigating for other major large scale effects, calculated and verified that Earth's rate of rotation had increased to the point that our days are now 1.8 microseconds shorter than before.

Redistribution of sufficient mass causes an axial shift , and the axial shift changes the moment of inertia. (mass's resistance to spin). When you redistribute enough mass around Earth, you cause a shift in the earth's axis, changing Earth's moment of inertia (resistance to spin). Because of conservation of angular momentum, changes in inertia result in changes in rotation rate, and changes in Earth's rotation rate are changes in the length of Earth's day.

The situation is analogous to a spinning ice skater pulling in her arms to increase her spin rate. Changes in inertia result in changes in rotation rate.

When a skater pulls in her arms, she decreases the radius distance between her body axis and her arms (and all the atoms in her arms). Angular momentum is the measurement of that distance; pulling in her arms changes her angular momentum measurement. The total angular momentum stays constant, no matter what, so unless she moves some other part of her body as compensation, she can't keep moving at the same speed. She speeds up when she pulls in her arms because she reduced the distance between her arms and her body, and ALSO didn't move another body part to compensate for the reduced distance amount. This process, called the Law of Conservation of Angular Momentum, says angular momentum stays constant , no matter what. The skater pulls in her arms, her angular velocity decreases, her moment of inertia increases, and she spins faster. And vice versa. When angular velocity increases, the moment of inertia decreases to keep the angular momentum constant. Recent quakes moved around enough mass on our planet that our planet now spins faster, and our days are shorter.

When everyone is in a hurry, we need more courtesy and patience, not less. Give yourself extra time to do chores, because to begin with, you had less time for them. Be early when it comes to "making the ferry". Today you have even less time to be on time and to plan your time accordingly. And this is not as silly as it seems.


We hope this information is helpful to you. Thanks for reading. Merci de votre visite.
