f you can crack the code above, congratulations — you’re the first person to do so. And you may be helping solve a murder case in the process.

On June 30, 1999, a 41-year-old man named Ricky McCormick was found dead in a field about 15 to 20 miles northwest of St. Louis, Missouri. McCormick was unmarried but had at least four children. He was unemployed on and off for years. He had previously been convicted of statutory rape but was out on parole. He had chronic lung and heart problems and, five days prior to his death, was in a hospital in St. Louis getting a checkup. (He left the same day.) At the time of his death, he had multiple home addresses in the area.

The FBI investigated his death and found virtually no answers. McCormick’s body was badly decomposed (the FBI identified his body via his fingerprints), preventing authorities from determining the cause of death. McCormick’s whereabouts for the days between that doctor’s visit and the discovery of his body were, and remain, unknown. How he got to this field is also unknown, as McCormick didn’t know how to drive and public transportation did not service the area. There were no known people who would have the motive to kill him, nor any signs of suicide.

But while there were few answers, there were some clues. Two, in fact. In McCormick’s pockets were two notes, one above and another seen below.

 

note2

 

In March of 2011 — more than a decade after McCormick’s death — the FBI disclosed that these potential clues existed. The Bureau’s reason for not disclosing this sooner isn’t known, but its reasons for doing so then are. The FBI was stumped, and wanted help. They set up a webpage, here – still active, as of this writing — asking the world to assist in deciphering the messages. Despite the “outpouring of responses” to the call to action (the FBI had to set up a separate page solely for the gathering of theories), the code remains encrypted.There is, of course, the chance that McCormick (or whomever wrote the note) simply put gibberish to paper.

Have any ideas? You can let the FBI know via this link, but don’t expect to be showered in money if you do — there’s no reward being offered.

Bonus fact: The CIA has an uncracked-code mystery of its own. As reported by Wired, in 1988, the Agency commissioned the creation of a sculpture named “Kryptos” which contains four encrypted messages. Three of them were solved (here are the solutions) after its dedication in 1990, but the fourth one remains unsolved to this day. The creator of the sculpture, an artist named James Sanborn, asserts that there is, indeed, a real message hidden within, and has given a clue or two to its meaning.

Monkey Island

Dan Lewis continues to provide us with interesting facts.

Cayo Santiago is a small island about half a mile off the southeast coast of Puerto Rico. Shaped like an upside down L, the island is only about 140,000 square meters in area and has a population of zero.

Unless you count the 900 or so monkeys living there, that is. (And apparently, they bite.)

In 1938, a team of researchers relocated 409 Rhesus monkeys from India, hoping to build a wilderness preserve for them so that Western scientists could study the monkeys in something akin to their natural habitat. Nearly seventy-five years later, the experiment continues, successfully. Accounts vary, but there are currently between 850 and 950 monkeys, all descended from those imported in 1938, living in the wild on Cayo Santiago — now, colloquially, also referred to as “Monkey Island.”

Roughly a dozen researchers from mainland Puerto Rico visit the island daily, observing and interacting with the army of primates in hopes of gathering data and gleaning insight into their society. Some researchers — ethologists — observe the monkeys, staying out of sight if possible. But others look to interact with Cayo Santiago’s residents. One of these researchers, Laurie Santos, is an evolutionary psychologist from Yale University. Her studies focus on the something called “theory of mind” — how humans can infer what others are thinking based on their behavior, even if the people (or animals) being observed are not speaking. For example, our body language and facial expressions send signals which most other people can rely upon to figure out, with typically solid accuracy, what is going on in our brains. That skill, Santos believes, developed somewhere along the way, and the Cayo Santiago monkeys may have unique value. As she told Smithsonian magazine, ”if you see something in a primate, you can use it as a window into the evolutionary past of human beings.” Being able to interact with a large number of monkeys has led Santos to conclude that “the gap between human and animal cognition, even a chimpanzee, is greater than the gap between a chimp and a beetle.”

That cognitive gap probably explains why Monkey Island is closed to tourists. The monkeys can be vicious, lacking even the most basic regard for human visitors. Even the researchers need to take caution while visiting, eating their lunches in a chain-link fence-enclosed area to prevent the animals from stealing a snack. And as the sign above suggests, the primates are not ones to give much thought as to what they stick their teeth into.

Slinky Magic

Do try this at home!

Take a Slinky or a generic version thereof — the bigger, the better. Find a balcony or window a few stories above ground, making sure that outside, there aren’t any passersby coming. Dangle the Slinky out the window until it is mostly still. You’ll want the other end of the Slinky to be about half way to the ground — if it isn’t, go up another few stories. If you have the required distance, count to five and let the Slinky go.

The top will fall. The bottom will wait until the top gets there.

Don’t have a Slinky handy? Or can’t get to a third story window? Watch the video below (or check out this animated gif):

See? The top falls. The bottom waits.

What’s going on here? The Slinky comes with a small, barely visible jet pack which allows– no, wait. It’s just physics, even if counterintuitively so.

Let’s start with gravity. Drop something — a ball, your cell phone (which certainly happens all too often), a Slinky, or anything, and gravity will start to pull it down. That’s pretty straightforward. It’s why the top of the Slinky immediately falls once released, and it’s why we expect the rest of the Slinky to fall as well. But that’s not the only force acting on the Slinky. There’s also the tension in the spring.

From the perspective of the Slinky’s bottom, the tension is an upward force. Literally, the tension is pulling the bottom of the Slinky back up toward the top. When you are holding the top end of the Slinky, tension is what keeps it from unraveling entirely and falling to the ground as it stretches and dangles. When you drop it, the spring’s tension doesn’t just disappear, It’s still there and, in this case, pulling up at the same rate that gravity is pulling it downward. So the bottom stays in place as the Slinky compresses.

But in the end, gravity wins. When the top and bottom meet, the tension goes to zero, and the bottom of the Slinky joins the top in its descent back to the ground.
