A particle becomes ionized when it loses an electron.

Candle-Powered Electric Candle. After seeing news reports about Hurricane Sandy and hearing the ordeal that all of my family and friends in New York and New Jersey went through, it got me thinking about my own emergency preparedness.
San Francisco - after all - sits atop some very active fault lines. As local geology fans always like to point out - statistically speaking - we are long overdue for a large quake. This forecast is bad news for me, because I don't think that I am very prepared. I might have a few gallons of bottled water in the back closet, but I was ordered not to look in there until after Christmas... so...
I am really not sure. I have been thinking a lot lately about being more prepared, and what supplies we should have on hand for when the 'big one' hits. After assessing the problem, it became apparent to me that after a few days of constant lighting, all of my batteries will be dead. Do not leave this contraption unattended. Tonight. Tonight’s chart shows Polaris and the Big and Little Dippers for a September evening.
You can use the Big Dipper to find Polaris, which is also known as the North Star. Notice that a line from the two outermost stars in the bowl of the Big Dipper points to Polaris. And notice that Polaris marks the tip of the handle of the Little Dipper. The northern sky is a large clock, with Polaris at its center. The hour hand is a line drawn through Dubhe and Merak, the two pointer stars of the Big Dipper. The Big and Little Dippers: All you need to know EarthSky astronomy kits are perfect for beginners.

The Big Dipper swings full circle – 360 degrees – around Polaris in about 23 hours and 56 minutes. If you’re in the northern U.S., Canada or at a similar latitude, the Big Dipper is circumpolar for you – always above the horizon. What if I jumped into a tunnel through the center of the Earth?" Want to really get away from it all?
The farthest you can travel from home (and still remain on Earth) is about 7,900 miles (12,700 kilometers) straight down, but you'll have to journey the long way round to get there: 12,450 miles (20,036 kilometers) over land and sea. Why not take a shortcut, straight down? You can get there in about 42 minutes -- that's short enough for a long lunch, assuming you can avoid Mole Men, prehistoric reptiles and underworld denizens en route. Granted, most Americans would end up in the Indian Ocean, but Chileans could dine out on authentic Chinese, and Kiwis could tuck into Spanish tapas for tea [sources: NOVA; Shegelski]. Of course, you'd be in for a rough ride. For sake of argument (and survival) let's pretend the Earth is a cold, uniform, inert ball of rock. At the Earth's surface, gravity pulls on us at 32 feet (9.8 meters) per second squared.
