10 Shipwrecks You Can Visit

UNESCO says that there are no less than three million shipwrecks lost beneath the waves, their locations just waiting to be discovered. But for tourism purposes, the most interesting shipwrecks are those we already know about—and can visit. These ten shipwrecks all have intriguing stories, and they’re all places where you can step foot, although in some cases a boat (and possibly scuba gear) may be necessary. Remember: look, don’t touch, since removing artifacts can spoil the chance for valuable archeological research. 

1. Bessie A. White, Fire Island, New York 

The 200-foot schooner Bessie White wrecked about a mile west of Smith Point County Park in 1922 while laden with coal and bound for Newfoundland. The crew escaped, but the three-year-old ship ran aground. When Superstorm Sandy hit Fire Island in October 2012, it revealed the battered remnants of the ship's hull, which had been carried west to a spot near Skunk Hollow in the Otis Pike Fire Island High Dune Wilderness. The National Park Service sometimes leads hikes to the wreckage, whose location over time provides scientists with clues to how the landscape of Fire Island has changed.

2. MS World Discoverer, Solomon Islands

A Danish cruise ship built in 1974 that once carried passengers to polar regions, the MS World Discoverer ran aground in the Solomon Islands in 2000. No lives were lost—all the passengers escaped via ferry after an uncharted rock pierced the ship's hull. As of fall 2014, the wreckage was still a tourist attraction in Roderick Bay in the Nggela Islands, listing heavily on its side against the shore. 

3. Peter Iredale, Warrenton, Oregon 

Now a haunting ruin along the Oregon coast, the Peter Iredale was once a four-masted steel barque sailing vessel owned by British shipping firm Iredale & Porter. In September 1906, the ship left Santa Cruz, Mexico, on its way to Portland, Oregon, where it was supposed to pick up wheat bound for the United Kingdom. But a heavy wind and strong current sent her on to the breakers and she ran aground at Clatsop Beach, with three of her masts snapping from the impact, according to the Oregon History Project. The wreckage became an immediate tourist attraction, and despite being buffeted by the wind and waves ever since, it remains so today. It’s now part of Fort Stevens State Park. 

4. Navagio Beach, Zakynthos island, Greece 

This shipwreck in the Ionian Islands gives the beach its nickname: Smugglers Cove. Supposedly, the Panagiotis, which wrecked there in the early 1980s, was smuggling cigarettes and possibly worse. The rusting hulk of the boat is far from the only thing to see, however; the beach (which is also known as Shipwreck Beach) also attracts visitors for its clear turquoise waters and pristine pale sand. It’s also one of the most popular spots for BASE jumping in the world. (Sadly, it can only be accessed by boat.) 

5. SS Maheno, Fraser Island, Australia

Once an ocean liner that plied the Tasman Sea between New Zealand and Australia, the SS Maheno was also used as a hospital ship for the New Zealand navy during World War I. She was later sold to a Japanese ship-breaking company for scrap, but broke apart in a cyclone on its journey to Japan in 1935. Since washing ashore on Australia's Fraser Island, the ship has become a major tourist attraction, despite not being particularly safe.

6. SS Oregon, Long Island Sound, New York 

Once the fastest liner on the Atlantic, the SS Oregon sunk in 1886 just 15 miles off New York after hitting an unidentified schooner, often thought to be the Charles R. Morse. After an unsuccessful attempt to plug the hole in the hull with canvas, the captain ordered the ship abandoned, even though there were only enough lifeboats for half the ship's 852 passengers. (Fortunately, another ship arrived to save the passengers, and there were no casualties.) Today the wreck is a popular dive site in Long Island Sound. Although the ship's hull and decks have disintegrated over the years, the engine and boilers remain, among other remnants.

7. Uluburun, Bodrum, Turkey 

Granted, it's in a museum, but the Uluburun wreck, which sank off the coast of Turkey during the late Bronze Age, is one of the oldest ships ever found—it dates back 3,500 years. A local sponge diver found the wreck of the Uluburun off the southwestern coast of Turkey in the early 1980s. Archeologists then spent 11 years studying the ship, collecting 20 tons of artifacts, including the remains of fruits and nuts, pottery, jewelry, tools, and weapons. No one knows who built the ship or where it was headed, but judging by the amount of gold onboard, someone rich was involved. The remains of the ship and its cargo, as well as a life-sized replica, are kept the Bodrum Museum of Underwater Archaeology

8. MV Captayannis, River Clyde, Scotland 

Once a Greek sugar-carrying ship, the MV Captayannis has become a de facto home for birds and other wildlife since sinking in Scotland's River Clyde in 1974 during a terrible storm. (The collision with a BP oil tanker also didn't help.) The shallow waters around the wreck make it relatively accessible, and the ship seems likely to stay where it is, since its precise ownership is something of a mystery. 

9. La Famille Express, Turks and Caicos Islands 

Built in 1952 in Poland, La Famille Express served a large part of its life in the Soviet Navy (where it was known as Fort Shevchenko), before being sold and re-christened with its new name in 1999. It wrecked under mysterious circumstances around 2004. It now lies in just a few feet of water, an attractive landmark for boaters in the Turks and Caicos. 

10. Eduard Bohlen, Namibia

This wreck is unusual for being buried entirely in the sand—it's now stranded about a quarter mile away from shore. A 2,272-ton cargo ship that wrecked off Namibia's Skeleton Coast in 1909 in thick fog, the ship since has drifted so far from the water it's now completely land-locked.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

One Bite From This Tick Can Make You Allergic to Meat

We like to believe that there’s no such thing as a bad organism, that every creature must have its place in the world. But ticks are really making that difficult. As if Lyme disease wasn't bad enough, scientists say some ticks carry a pathogen that causes a sudden and dangerous allergy to meat. Yes, meat.

The Lone Star tick (Amblyomma americanum) mostly looks like your average tick, with a tiny head and a big fat behind, except the adult female has a Texas-shaped spot on its back—thus the name.

Unlike other American ticks, the Lone Star feeds on humans at every stage of its life cycle. Even the larvae want our blood. You can’t get Lyme disease from the Lone Star tick, but you can get something even more mysterious: the inability to safely consume a bacon cheeseburger.

"The weird thing about [this reaction] is it can occur within three to 10 or 12 hours, so patients have no idea what prompted their allergic reactions," allergist Ronald Saff, of the Florida State University College of Medicine, told Business Insider.

What prompted them was STARI, or southern tick-associated rash illness. People with STARI may develop a circular rash like the one commonly seen in Lyme disease. They may feel achy, fatigued, and fevered. And their next meal could make them very, very sick.

Saff now sees at least one patient per week with STARI and a sensitivity to galactose-alpha-1, 3-galactose—more commonly known as alpha-gal—a sugar molecule found in mammal tissue like pork, beef, and lamb. Several hours after eating, patients’ immune systems overreact to alpha-gal, with symptoms ranging from an itchy rash to throat swelling.

Even worse, the more times a person is bitten, the more likely it becomes that they will develop this dangerous allergy.

The tick’s range currently covers the southern, eastern, and south-central U.S., but even that is changing. "We expect with warming temperatures, the tick is going to slowly make its way northward and westward and cause more problems than they're already causing," Saff said. We've already seen that occur with the deer ticks that cause Lyme disease, and 2017 is projected to be an especially bad year.

There’s so much we don’t understand about alpha-gal sensitivity. Scientists don’t know why it happens, how to treat it, or if it's permanent. All they can do is advise us to be vigilant and follow basic tick-avoidance practices.
