Days getting Shorter?


Once again another thought provoking story from Yahoo!

The massive 8.8 earthquake that struck Chile may have changed the entire Earth's rotation and shortened the length of days on our planet, a NASA scientist said Monday.
The quake, the seventh strongest earthquake in recorded history, hit Chile Saturday and should have shortened the length of an Earth day by 1.26 milliseconds, according to research scientist Richard Gross at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
"Perhaps more impressive is how much the quake shifted Earth's axis," NASA officials said in a Monday update.
The computer model used by Gross and his colleagues to determine the effects of the Chile earthquake effect also found that it should have moved Earth's figure axis by about 3 inches (8 cm or 27 milliarcseconds).
The Earth's figure axis is not the same as its north-south axis, which it spins around once every day at a speed of about 1,000 mph (1,604 kph).
The figure axis is the axis around which the Earth's mass is balanced. It is offset from the Earth's north-south axis by about 33 feet (10 meters).
Strong earthquakes have altered Earth's days and its axis in the past. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami, should have shortened Earth's days by 6.8 microseconds and shifted its axis by about 2.76 inches (7 cm, or 2.32 milliarcseconds).
One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond. It increases in the winter, when the Earth rotates more slowly, and decreases in the summer, Gross has said in the past.
The Chile earthquake was much smaller than the Sumatran temblor, but its effects on the Earth are larger because of its location. Its epicenter was located in the Earth's mid-latitudes rather than near the equator like the Sumatran event.
The fault responsible for the 2010 Chile quake also slices through Earth at a steeper angle than the Sumatran quake's fault, NASA scientists said.
"This makes the Chile fault more effective in moving Earth's mass vertically and hence more effective in shifting Earth's figure axis," NASA officials said.
Gross said his findings are based on early data available on the Chile earthquake. As more information about its characteristics are revealed, his prediction of its effects will likely change.
The Chile earthquake has killed more than 700 people and caused widespread devastation in the South American country.
Several major telescopes in Chile's Atacama Desert have escaped damage, according to the European Southern Observatory managing them.
A salt-measuring NASA satellite instrument destined to be installed on an Argentinean satellite was also undamaged in the earthquake, JPL officials said.
The Aquarius instrument was in the city of Bariloche, Argentina, where it is being installed in the Satelite de Aplicaciones Cientificas (SAC-D) satellite. The satellite integration facility is about 365 miles (588 km) from the Chile quake's epicenter.
The Aquarius instrument is designed to provide monthly global maps of the ocean's salt concentration in order to track current circulation and its role in climate change.

NBC say what???

ept_sports_oly_experts-539821375-1267415145.jpg


Clearly NBC needs to work on their Public Relations and Networking skills. How could they think that the millions of viewers watching the NBC coverage of the 2010 Winter Olympics closing ceremonies would want to be rudely interrupted to watch their new reality show? It almost felt planned, like they thought hey, we have a million or so people watching our channel right now, lets just plug in our new reality show in the middle and see what people think, who care about world unity when Jerry Seinfeld has a new show coming out? Anyway here is the full story found on Yahoo! Enjoy and let me know what you think.

How did NBC choose to end its 865 hours of Winter Olympic coverage? By barely acknowledging that said coverage was ending.

In a bizarre conclusion to its telecasts of the 2010 Vancouver Games, NBC awkwardly cut away to air the premiere of the much-hyped reality show, "The Marriage Ref." Viewers were abruptly informed that coverage of the Ceremony would continue at 11:30 p.m. ET.

Here's how it went down: At 10:29 p.m. ET, the network abruptly cut to commercial after singer Michael Buble finished a swinging, Sinatra-like rendition of "The Maple Leaf Forever". After a few ads, NBC cut back to a wide shot of the ongoing Ceremony (there were a number of inflatable animals on the floor at BC Place, making it look like an indoor version of the Macy's Day Parade) and viewers heard Bob Costas say:

"We're back in an hour with the Closing Ceremony party from Vancouver. Nickleback and Avril Lavigne are among the acts that will be performing. But right now we take you to the premiere of Jerry Seinfeld's new series, 'The Marriage Ref.' "

And then, suddenly, coverage of the Olympics was over and the intro to Jerry Seinfeld's show began.

All that NBC does in over-dramatizing the Games and that's how they choose to end coverage for a vast majority of viewers? (Because, let's face it, most people aren't tuning in for the 11:30 p.m. coverage.) No Costas sign-off? No end credits? No cheesy summation of the triumphs of the Olympic spirit? Where's our closure?

PMYi stands for Peak My Interest. I started this blog so that I could have a platform to give my thoughts on the the news of the world. I am a communications major at BYU-Idaho and am fascinated with how organizations, new networks, and people communicate. This site is purely my opinion and I don't own any of the logos, images, or quotes that may appear on the site.
