This article at Discover Magazine has nothing to do with the science fiction stories we are so familiar with. Author Sean Carroll looks at time travel as a physicist. He says if time travel were possible (and it might be), there would be no paradox, because we cannot change what has already happened. Ever. Then it gets weird.

Imagine that we have been appointed Guardian of the Gate, and our job is to keep vigilant watch over who passes through. One day, as we are standing off to the side, we see a person walk out of the rear side of the gate, emerging from one day in the future. That’s no surprise; it just means that you will see that person enter the front side of the gate tomorrow. But as you keep watch, you notice that he simply loiters around for one day, and when precisely 24 hours have passed, the traveler walks calmly through the front of the gate. Nobody ever approached from elsewhere. That 24-hour period constitutes the entire life span of this time traveler. He experiences the same thing over and over again, although he doesn’t realize it himself, since he does not accumulate new memories along the way. Every trip through the gate is precisely the same to him. That may strike you as weird or unlikely, but there is nothing paradoxical or logically inconsistent about it.

22-year-old Julia Popova was mugged on her way home from work in Moscow. She struggled with the purse-snatcher and was so shocked by the experience that she didn't realize he'd left a 6-inch knife sticking in her neck at the top of her back!

Her horrified parents rushed her to hospital where surgeons managed to remove the blade without damaging Julia's spine.

"Shock had kicked in and her body prevented her from feeling any pain. She simply walked home without feeling the knife in her back," said one medic.

31-year-old Andi Susanto of Jakarta, Indonesia, received compensation from a tobacco company after a cigarette exploded in his face and knocked out six of his teeth while he was riding his motorcycle.

A spokesman for Clas Mild cigarettes, the brand Mr Susanto had been smoking, said there were no plans for a recall.

"We are communicating with the police and still waiting on the forensic laboratory tests," Iwan Sulistyo told the Jakarta Globe.

Susanto accepted the settlement, and said he was planning to give up smoking anyway. Link -Thanks actor212!

Sisso the swift was found with a damaged wing seven months ago. The little bird has healed, but must learn to fly all over again with some inventive physical therapy. Sisso takes flying lessons suspended from a custom-made sling!

The swift is being treated at an Israeli animal hospital and it is thanks to this ingenious device - which resembles a mobile in a child's bedroom - that he can practise flying.

Fitting snugly into a red tube-like vest made of bandages and gauze pads, Sisso has holes for his head, wings, feet and tail.

A string is fixed to the harness and attached to the ceiling which allows him to whizz around a room at the Ramat Gan Safari Park Animal Hospital without falling to the floor.

However, until the muscles in his weakened right wing become strong enough, he will be kept indoors and in the sling.

Sisso will be freed when he can fly normally again. Link -via mental_floss

On February 2nd of every year, people wait to see if their local groundhog comes out of its winter nest. The superstition says that if the groundhog sees its shadow, it will be scared and run back into hiding, and we will have six more weeks of bad weather. If the groundhog stays out, better weather is on the way. The most famous groundhog in the US is Punxsutawney Phil, who is escorted out of his pen with pomp and ceremony every year. However, PETA doesn't think this is a good idea.

People for the Ethical Treatment of Animals says it's unfair to keep the animal in captivity and subject him to the huge crowds and bright lights that accompany tens of thousands of revelers each Feb. 2 in Punxsutawney, a tiny borough about 65 miles northeast of Pittsburgh. PETA is suggesting the use of an animatronic model.

But William Deeley, president of the Inner Circle of the Punxsutawney Groundhog Club, says the animal is "being treated better than the average child in Pennsylvania." The groundhog is kept in a climate-controlled environment and is inspected annually by the state Department of Agriculture.

Deeley considers this a publicity stunt. http://www.washingtonpost.com/wp-dyn/content/article/2010/01/27/AR2010012701394.html

It's a terrifying scenario you may have dreamed about: falling to earth from a high altitude. A very few people have survived such an event. Popular Mechanics has a survival guide that will take you longer to read than the six mile fall would take.

Things are bad. But now’s the time to focus on the good news. (Yes, it goes beyond surviving the destruction of your aircraft.) Although gravity is against you, another force is working in your favor: time. Believe it or not, you’re better off up here than if you’d slipped from the balcony of your high-rise hotel room after one too many drinks last night.

Or at least you will be. Oxygen is scarce at these heights. By now, hypoxia is starting to set in. You’ll be unconscious soon, and you’ll cannonball at least a mile before waking up again. When that happens, remember what you are about to read. The ground, after all, is your next destination.

This post is not for the faint of heart. http://www.popularmechanics.com/science/air_space/4344036.html?page=1 -via Metafilter

Dark Roasted Blend takes a look at artful and unusual bank notes from around the world, past and present. You thought Zimbabwe's inflation was outrageous when they issued the 100 billion dollar notes? Now they have 100 trillion dollar notes! That kind of hyperinflation is not new, as you'll see in this post. Link

Television programmers have to take chances in order to find the Next Big Thing. Sometimes those leaps of faith fail miserably -and expensively! Personally, I've never seen any of these shows except for The Tonight Show with Conan O'Brien, but that wasn't so much a flop as it was an expensive mistake. Among the rest are some truly weird ideas. Remember Cop Rock?

A police procedural musical would be one of the weirder ideas in television history, but if ABC hadn’t marketed the show and spent so heavily on the production I imagine Cop Rock would be looked at as just another weird flop, one of the probably hundreds in television history. Instead ABC seemed really, truly convinced that a musical cop show was going to work.

The show actually made it 11 episodes, which is still 11 more than I would have expected. I mean really, just for emphasis, this was a musical drama about our nation’s legal system, and it cost $2 million per episode in 1990 dollars.

The Museum of Unintended Use chronicles the way people use things for purposes other than what they were designed for. Some uses are silly, some are stretching the definition of common sense, and some are downright clever, such as this trick to keep cats from bothering houseplants. Link -via the Presurfer

Fifty-nine years ago today was the first time a television audience got to watch an atomic blast broadcast live as it happened. KTLA in Los Angeles hid a crew on the roof of a hotel in Las Vegas, waiting for the top secret Ranger Easy bomb test in Frenchman Flats, Nevada. The blast went off at 5:30AM on February 1st, 1951. Viewers got up early to see their TV screens go white.

We stayed on the air, they waited for the right time, and all of a sudden there was the flash. The people watched it, Gil described it, Lane talked about it, and that was our telecast. That one flash. You just see this blinding white light. It didn’t seem real. We didn’t have videotape. You couldn’t say, “Let’s look at it again.”

A year later, all the networks carried live coverage of nuclear tests. Link

Wired also has a collection of nuclear bomb videos. Link

I collect links to bizarre niche blogs. This one takes the cake for sheer randomness. Selleck Waterfall Sandwich delivers exactly what it says -a collection of images all combining actor Tom Selleck and a sandwich on a background featuring a waterfall. The site even has a theme song, if you can call it a song. The picture here stars a Spam sandwich. Link -via mental_floss
