Why the US Navy wanted to communicate using whale language

In the 1960s and 1970s, the US Navy researched whether they could use synthesized whale sounds for submarines to have encoded conversations across long distances underwater. Called Project COMBO, it was a fascinating attempt at biomimicry. The project's culminating experiment even attracted a pod of whales. Alas, Project COMBO ultimately failed, but it makes for a great story. From Cara Giaimo's article in Atlas Obscura:

Positioning themselves off of Catalina Island, 150 feet underwater, they blasted their squeaky, warbly codes through a transmitter. The receiver, placed at varying distances away, plucked the messages out of the noise flawlessly. Another test, in the fall, went deeper down and extended the range. In June of 1974, they sent out a real submarine, the USS Dolphin, which successfully transmitted sounds to a receiving ship—and, in a true vote of confidence, attracted a pod of pilot whales.

After these testing successes, researchers were left with a lot of work to do. Although they had the pilot whale on lock, they wanted to expand their repertoire by inventing “techniques and equipment to synthesize large whale sounds and small whale screams.” They still had to create scalable versions of their tools, including the call generator and the spectrograph-recognizer. Looking ahead, more problems loomed: the researchers figured this was a good enough idea that the Soviets would steal it, at which point American submariners would need to add another skill to their arsenal. “Fleet sonarmen must become more familiar with bioacoustic signals,” they wrote—inspiring thoughts of submarine soldiers, facing long days underwater, taking up sonic seal- and whale-watching.

On the receiving side, submarines were already equipped with spectrographs, which transform incoming sound waves into visual charts. Since the coded pilot whale sounds were synthesized, and therefore identical, receiving and decoding them was merely a matter of recognizing a particular pattern as it came through the machine. A real whale’s call, with its unique combinations of pitch and timbre, would produce a slightly different readout, and could be weeded out as noise with the help of recognition software.

“It was never successful,” writes Dr. Christopher Willes Clark, founder of the Cornell Bioacoustics Research Program, in an email. “The process of projecting coded ‘whale’ sounds out to functional distances is not viable.” Despite the promise of those initial tests, the technological barriers proved too large to overcome, and subsequent attempts in future years also failed.

Sick of people whitewashing Martin Luther King Jr.’s legacy, artist Daniel Rarela created this series featuring quotes from King's “Letter From A Birmingham Jail.” The accompanying images are both historical and contemporary. As Rarela told Mic: “As a graphic designer, I wanted to shatter this false image of a Martin Luther King who everyone loved, never got arrested, was universally popular and made zero privileged people feel uncomfortable or angry enough to want to kill him.”

High school teacher Joe Howard (the guy who made the "How loud would it be if all of the cats in the world meowed at the same time?" video I posted a couple of weeks ago, is back. This time, he shows how to come up with a formula to determine how long would it take a pay-it-forward chain to reach 7.4 billion people

Many people are familiar with the concept of paying forward, but how quickly can it actually spread if we commit to it? This video calculates how many layers of pay it forward would need to happen successfully for the chain to reach everyone on the planet.

Chew toys that last a giant dog multiple rainy days

http://feeds.boingboing.net/~r/boingboing/iBag/~3/2irvU8zt5zM/chew-toys-that-last-a-giant-do.html

http://boingboing.net/?p=505401

I have a giant dog. Nemo is a Great Pyrenees. Finding toys that'll entertain him, without becoming shredded or hazardous, is challenging.

This rainy season we've been trapped inside quite a bit. Nemo gets a bit of nervous energy when this happens, and if I don't channel it into fun toys and distractions I'll be calling a carpenter.

Starmark's Wheeler is the longest lasting and most durable in their Everlasting Treat line. These toys allow a fitted, dense chewable to be inserted into a toy with the idea of making the treat accessible but still require work to chew. Nemo loves the Chicken and Bacon flavored treats, and one of either will last 2 days of chewing at it, or more. After several months of use The Wheeler itself has some small tears, but it has withstood multiple hours of chewing. Nemo frequently carries it around the house with him, keeping the Wheeler close at hand incase he wants to start working on it again.

The Amazon price on the treats is around 60% less than what I was paying at my local petshop.

Nemo's other favorite rainy day distraction these days, aside from barking, is his trusty old XXL KONG Extreme. I've only had to buy one. This sucker lasts, and lasts. My smaller dog, Pretzel, is the second generation of Cavalier King Charles Spaniel to chew hers. These toys have not even got teeth marks on them, after years of abuse. The KONG is one of the easiest toys I've found to distract a dog for 30-45 minutes. Slime some peanut butter (and bacon bits) into it, and away the dogs go.

William Onyeabor, Nigerian funk music pioneer, RIP

William Onyeabor, the Nigerian musician who pioneered African electro-funk in the 1970s, has died. He was 70-years-old. Onyeabor's music experienced a resurgence in recent years thanks to the Luaka Bop label's reissues of his deeply groovy albums. From Luaka Bop:

It is with incredibly heavy hearts that we have to announce that the great Nigerian business leader and mythic music pioneer William Onyeabor has passed away at the age of 70. He died peacefully in his sleep following a brief illness, at his home in Enugu, Nigeria. An extraordinary artist, businessman and visionary, Mr. Onyeabor composed and self-released 9 brilliant albums of groundbreaking electronic-funk from 1977-1985, which he recorded, pressed and printed at Wilfilms Limited—his personal pressing plant in southeast Nigeria.

For people in his hometown of Enugu, Nigeria, Mr. Onyeabor was simply referred to as "The Chief”. He was known for having created many opportunities for the people in his community. In his early 30s, he traveled the world to study record manufacturing, so that he could build, "the greatest record manufacturing business in all of West Africa." After those successful years as an artist and record label President in the 1980's, he opened a flour mill and food processing business. In 1987 these new business ventures saw him awarded West African Industrialist of the Year—just two years after the release of his most successful song "When The Going is Smooth and Good", and what should have been the height of his musical career. He was given the honorary title "Justice of the Peace"—a local judicial position elected by the community to provide independent legal ruling. In the early 1990's, he became the President of Enugu's Musician's Union and Chairman of the city's local football team, The Enugu Rangers. Despite all of these extraordinary achievements, his biography was always shrouded in mystery—some claimed he had studied filmmaking in the Soviet Union, while others placed him in France or Great Britain. To his great amusement (and ours too for that matter), this mythic image was at times so deeply ingrained, that we often encountered people who were convinced that he didn't actually exist. Whenever we shared this with him, or would ask him a question about his past, he would just smile and say, "I only want to speak about God."

After five long years of painstaking waiting, negotiating and intense research, we were finally able to release “Who is William Onyeabor?” in 2013 and his music and story took the world by storm. The release was featured in major newspapers, radio and television stations around the world. Time Magazine listed him as number 4 on a shortlist of that year’s best albums. In 2014, the film documentary “Fantastic Man” followed, as well as the “Atomic Bomb! Who is William Onyeabor?” live shows, which travelled to the most regarded festivals and music venues worldwide-starring over 50 special guests from many diverse generations, genres and backgrounds.

Still, William Onyeabor would never speak about himself and for a long time refused any of the many interview requests that came his way. For an artist that had never performed live in his entire life, he repeatedly, and very sadly, would always decline our invitations to take part in any of the joyous celebrations that were created in his honor. Having become Born Again in the latter part of life, he had turned his back on the music from the earlier part of his life.

As one of the absolutely smartest people we ever encountered—William Onyeabor was always in charge, whatever the situation may be (and even though he was living in a fairly isolated part of rural West Africa). As can be heard in many of his songs, he looked at the world from a bird's eye view. He would watch American, Chinese and European news simultaneously, so he could learn about the different points of view from around the world. In his later years, he was still conducting business as usual. Whenever we visited him in Nigeria, he welcomed us warmly into his home. Whether it be at his palace outside of Enugu or via crackly phone lines to America, he always made us laugh. As is also very evident in his songwriting—another example of his true intellect and originality—he had the greatest sense of humor. His life and accomplishments will never cease to astonish us. More than anything, and still to this very day, his music continues to live on—nearly 40 years after it was originally released.

Chief William Ezechukwu Onyeabor is survived by his wife, children, and four grandchildren. We would like to send our deepest condolences to his family and thank each and every one of you who has helped share the love for his music around the world.

In the short and wonderfully intense nine years that we came to know him, he changed our lives in many ways. If he hasn't yet, we hope he will affect you too, one day.
