AKRON, Ohio -- Tiger Woods didn't break stride as he walked purposefully from the scoring trailer to the clubhouse at Firestone Country Club about 11:30 a.m. on Saturday.Normally Woods would have been preparing for a round rather than just completing one. And he certainly wouldn't have been flirting with finishing last in a tournament he had won seven times.But this isn't the same Woods who has dominated the World Golf Championships-Bridgestone Invitational. His driver is erratic, his irons lack precision and his putter has been decidedly uncooperative.And come Sunday, it appears more and more likely that Woods' stranglehold on the No. 1 spot in the Official World Golf Ranking -- a position he has held for 269 straight weeks since June 12, 2005 and 611 overall -- will have ended.Phil Mickelson, who is currently one stroke off the lead, needs only to finish fourth or higher -- as long as Woods is outside the top 44 -- to become world No. 1 for the first time in his career. Woods finished the third round 78th among the 80 players remaining in the field."Well, if Phil plays the way he's supposed to this weekend, then he'll be No. 1," said Woods, who declined to stop to talk with the media but did speak with a member of the PGA TOUR communications staff.Woods failed to break par for the third straight round on Saturday, shooting a 75 that left him 11 over. That's the highest 54-hole total in relation to par in Woods' pro career -- eclipsing the 10 over he shot at the 1998 and '96 TOUR Championships.In fact, Woods very well could be headed to his worth finish ever in a four-round event since he turned pro. The previous was a tie for 60th in the 1996 Greater Milwaukee Open -- in his debut.What makes Woods' struggles this week so surprising is his record on the South Course at Firestone Country Club.He has never finished outside the top 5 in 11 starts here dating back to the old NEC World Series of Golf. And Woods has won all but two of the nine Bridgestone Invitationals played at the South Course.And Woods' worst standing through three rounds at the Bridgestone Invitational in Akron? That would be a tie for fourth in 2003 when he went on to finish in the same spot.But this week the beleaguered Woods, who is still looking for his first win of 2010, has looked positively lost..There have been times that short putts haven't touched the cup. He ranks 80th this week in driving accuracy (15 of 42 fairways hit) and 78th in greens in regulation (25 of 54). He's made seven birdies, 16 bogeys and
Q&A: How do you calculate the radius of the penumbra during a solar eclipse?

Question by : How do you calculate the radius of the penumbra during a solar eclipse?
What is the formula to calculate the radius of the penumbra? I'm looking for the pure formula not necessarily in regards to the Earth and the moon.
If it helps, the formula for the length of the umbra can be found here: http://en.wikipedia.org/wiki/Eclipse
Best answer:
Answer by coldfieldgirlYou must know the umbra can fall on Earth's surface, but also it can just not fall on it (it is an annular eclipse then!).
So for your calculation of the penumbra on Earth's surface, the whole distance between Earth and Moon must be taken.
If you suppose:
s = radius Sun
m = radius Moon
N = distance Moon to Sun
D = distance Moon to Earth
then you can do the following:
angle A of one penumbra line = ArcTan ( ( s + m ) / N )
and the radius of the penumbra becomes m + D * Tan ( A )

Longest solar eclipse of the 21st Century. Wow. We were going to camp out in the park, but it was raining. Fortunately, twenty different broadcasting stations were covering the solar eclipse. Quite an amazing experience being in total darkness at 9:36AM. wiki article here because I'm a resourceful citizen: en.wikipedia.org

by de Paula FJ
Question by STAY OFF MY SHIT! C: If you could change the layout of the solar system, which of the following would cause a lunar eclipse to occu
If you could change the layout of the solar system, which of the following would cause a lunar eclipse to occur at least once every month in this hypothetical situation?
Make the Moon orbit Earth twice as fast.
Change the Moon’s orbital plane so it tilts the opposite way.
Relocate the Moon to twice its current distance from Earth.
Change the Moon’s orbital plane so it is in the same plane as Earth’s orbit around the Sun.
Best answer:
Answer by quizzard123If you could change the moons orbit to align with earth's orbit, we would indeed see an eclipse every month (at the time of the full moon)

Andrew Fazekasfor National Geographic News Published December 9, 2011This weekend sky-watchers across most of the globe will have the chance to watch at least some of the last total lunar eclipse until 2014.(See pictures from the previous total lunar eclipse in June The entire lunar eclipse will be visible in East Asia and the far western portion of North America that includes Alaska and Canada's Yukon and Northwest Territories. The spectacle will last nearly three and a half hours, starting on Saturday at 4:45 a.m. Pacific Time.Totality--when the full moon will be completely blocked from direct sunlight--will start at 6:05 a.m. PT and last until 6:57 a.m. PT.Part of the eclipse will be visible in Europe and Africa at moonrise, in the evening, said Raminder Singh Samra, an astronomer at the H.R. MacMillan Space Centre in Vancouver, Canada."Meanwhile, observers across the Pacific region of North America will get to see the sky show low in the western horizon at moonset, in the early morning," he said.Watch a live video feed of the total lunar eclipse from the Slooh SpaceCamera Live broadcast starts at 5:00 a.m. PT on Saturday.Painting the Full Moon RedLunar eclipses can occur only when the full moon, Earth, and the sun are aligned so that the moon crosses through Earth's shadow.Due to the moon's tilted orbit around Earth, lunar eclipses happen only a few times a year, Samra said. The eclipse can be full or partial, depending on how much of the lunar disk falls in our planet's shadow.(Watch a moon facts video Rather than going completely dark, the moon takes on a deep reddish hue during a total lunar eclipse."As the entire moon passes through the Earth's shadow cast by the sun in space, sunlight scattering off our planet's dusty atmosphere and subsequently reflecting off the surface of the moon will make it appear to change color," Samra said.Expect to see the lunar disk go from dark grey during the partial phase to reddish-orange during totality, he said.(See "Lunar Eclipse Pictures: When the Moon Goes Red." Partial Eclipses on the HorizonAfter Saturday's eclipse, sky-watchers are in for a dry spell--the cosmic lineup needed for a total lunar eclipse won't occur again until April 14, 2014.(Take a moon myths and mysteries quiz But the next partial lunar eclipse happens on June 4, 2012, when a chunk of the moon will appear to be gobbled up by Earth's shadow."The next few lunar eclipses that will occur will only be partial ones," Samra said, "so this will be our last chance to enjoy a total eclipse in quite some time."A total lunar eclipse does not need to happen for you to eclipse a friends or loved
