Purdy. But I’ve been thinking for a very long time on suit and belt and vest design and on how to improve not only weight distribution but ease and speed of equipment retrieval. I’ve tried some promising designs of my own especially with stuff running the sides of the torso (really quick retrieval but interferes with compactness of body and stealth and causes friction as you move) and need to come up with far better still.
What would really be ideal would be to have at most 7 tools/pieces of gear but each one be light, and multi-functional. And all of those within quick and easy reach. Everything else you could port on your back because you don’t need to access it often.
The real trick I think will be high end-high tech/multi-functional gear redesign, not so much carry redesign.
Ghostly Voices From Thomas Edison’s Dolls Can Now Be Heard
By RON COWENMAY 4, 2015
Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.
The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.
In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.
Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.
Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.
The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.
In 2014, the technology was made available for the first time outside the laboratory.
“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”
Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.
The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.
“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.
The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the Northeast Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.
Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.
Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.
At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.
Recently, the conservation center turned up another surprise.
In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.
Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.
“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.
The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.

An earlier version of this article misstated part of the name of a center in Andover, Mass. that recently acquired the Irene technology. It is the Northeast Document Conservation Center (not National center).
If possible always invent in imitation of Nature. God knows his designs.
By the way I have long considered and have experimented with the idea of a reactive liquid armor that both redirects projectile trajectories and disperses force in spread waves rather than attempts to meet it with direct resistance.
So I found this step forward to be doubly interesting. In construction method, in design, and as a pointer towards improved future capabilities.

Body armor suffers from a core tension: it must be light enough so the soldier wearing it can still fight effectively, but strong enough to actually stop bullets and shrapnel. Durable, shock-absorbing Kevlar is the current standard, but it can definitely be improved upon. What if, instead of making the armor itself a liquid, researchers borrow an armor design from creatures that move through it? A team at MIT, led by mechanical engineer Stephan Rudykh, designed a flexible armor inspired by fish scales.
Scale armor is almost as old as armor itself, with numerous examples found in ancient art from Rome to China. To improve on an ancient concept, the MIT team came up with a single metric for the armor’s value: protecto-flexibility (Ψ). This is “a new metric which captures the contrasting combination of protection and flexibility, taken as the ratio between the normalized indentation and normalized bending stiffness.” Working from a single metric, the researchers were able to greatly increase the strength of the armor while only modestly reducing its flexibility.
The practical implications of the study are hinted at by who funded it: the research “was supported by the U.S. Army Research Office through the MIT Institute for Soldier Nanotechnologies.” In the future, soldiers could have fish-scale suits of armor that are more flexible around joints and sturdier across the rest of the body, adding greater protection where none was before without diminishing any of the value of previous armor.
This armor is still in the early testing stages. “Flexibility and protection by design: imbricated hybrid microstructures of bio-inspired armor” only covers indentation tests, designed to see just how far the scales would bend when forced to. Next stages include trying the armor against bullets and shrapnel. If successful, the future of armor could look a heck of a lot like the past.
Google-owned Boston Dynamics has been making incredible robots long before it was purchased by Google.
Today it showed off its latest amazing robot, Spot – a smaller, more agile version of its WildCat robot.
Then, a BD team member decided to kick it, therefore dooming us all when robots become sentient.
Seriously, doesn’t this guy know that robots will be able to search YouTube in the future? Maybe the robots will just go after this guy and leave the rest of us robot-loving humans alone.
While I’m concerned about a robot uprising, Spot is incredibly impressive and maybe a little bit terrifying. The 160-pound, electrically-powered and hydraulically-actuated robot can walk and trot, so don’t bother try running away. It can also climb up stairs and walk up and down hills.
A sensor on the robot’s head helps it navigate over rough terrain.
While the thought of an army of these approaching you on the street might keep you awake at night, robots like Spot could be used to enter areas too dangerous for humans to occupy, or bring important supplies to destinations too treacherous for regular robots and too wooded for drones.
Plus, robots are cool. Just don’t go around kicking them.
Being an inventor myself I completely agree with the concept of “stripping away complexity” in order to produce light, flexible designs for most commercial and market applications.
Of course once the hoverbike becomes numerous in models and well-received or popular in usage additional complexities will be added back in, covering everything from entertainment, to pilot protections and security, to sensoring capabilities, to GPS navigation systems, to flight control automation and computerization, to running and warning lights, to communications . Just has occurred with cars and motorcycles. But for now, in the developmental and popularization phase, simplicity is the key to superior development.
By the way, back when I was in CAP this was already a Squadron and even a Wing project and I’ve seen several Air Force designs for basically the same kind of craft.
There is a show I very much enjoy watching when I can. It’s called Faith in History. Yes, the guy who conducts the show has a very pronounced sort of stumbling delivery when he speaks, but despite that, which often makes it difficult to follow him, I very much like the guy and the show is superb.
Today at lunch my youngest daughter and I sat down to watch the latest recorded episode because it was about George Washington Carver (and lately she had requested that she be allowed to study African history, which I’ll get back to in a moment) and although Carver is as American as peanut butter he was black and he was in my opinion the second greatest native inventor this nation ever produced (shy of Edison), and the very greatest bio-chemist (bar none) and one of the very greatest scientists this nation ever produced.
(Being particularly partial and interested in the biological, chemical, and genetic sciences myself I really like Carver and his work. He was brilliant, and well ahead of his time.)
Plus, I very much agree with his approach to invention, which I’ll recount later, as it is the closest parallel to my own method of invention that I have ever encountered in history.
Anyway it was an extremely good episode on Carver, dwelling upon both his scientific achievements and his personal life and faith.
My daughter seemed to enjoy the episode quite a bit, and as we watched it we would stop the show at various points and discuss science, God, technology, history, invention, writing, politics, and so forth. As is our wont when watching or discussing anything educational.
As for Carver’s methods of discovery, experimentation, inspiration, and invention they closely parallel my own, as he described in numerous letters, and in this speech:
“God is going to reveal to us things He never revealed before if we put our hands in His. No books ever go into my laboratory. The thing I am to do and the way of doing it are revealed to me. I never have to grope for methods. The method is revealed to me the moment I am inspired to create something new. Without God to draw aside the curtain I would be helpless.
Locking the door to his laboratory, Dr. Carver confided:
Only alone can I draw close enough to God to discover His secrets.”
The closest other two parallels I can name are found in the methods of Newton and Archimedes, both of whom I also seek to emulate when it comes to scientific discovery and invention. Archimedes in particular, and perhaps one day soon I will discuss the Agapoloid techniques I employ, which are derived to a large extent from Archimedes’ internal and mental mathematical and geometric laboratory.
After that and as we were cleaning up from lunch my daughter asked me if she could begin two independent courses of study.
My oldest child began her independent courses of study (that is to say she would choose two out of six curriculum areas to study in a self-directed fashion) at the age of 17 but my youngest wants to start now, at age 15.
Knowing now what I do about how advanced my children are and having loosened up a good deal over time with my second child I agreed and asked her to make me a list of what she most wanted to study.
Independent Areas of study are, of course, courses of study she chooses for herself, based upon her own interests, and in which she will do detailed research and work at the college level. Of course she’s been at college level in all her subject areas for a while now, but I mean detailed enough to write a collegiate term paper.
Her list was as follows:
1. Germany (pre-Nazi war era – my oldest daughter is a WWII history nut, as I was at her age, but my younger daughter seems to prefer much earlier time periods. Ancient, Classical, and Medieval.)
2. Africa (I am going to suggest to her that she begins her in-depth studies of Africa with either Egypt, or with Cush or Nubia or Ethiopia, as I have already done my own in detailed archaeological and historical studies of these ancient areas and kingdoms/realms as research for my novels. So I am already familiar with some excellent research materials. Plus those kingdoms were either advanced or relatively advanced. I’m also going to suggest she make an entirely separate study of ancient Alexandria. But in the end it will be up to her, those are just my suggestions.)
3. African Wildlife, Biology, and Geography
4. English Grammar (yes, being a writer this pleases me, but the girl actually loves grammar, English and Latin – I love language and primarily vocabulary and philology, but she loves grammar)
5. Italy (I’ve yet to ask her if she means ancient Italy, such as Etruscan/Roman eras, of if she means Medieval or Modern Italy, prior to World War II. If it’s ancient Rome that’s good though she just finished the Decline and Fall of the Roman Empire and if Medieval Italy I’ll suggest studying Florence and Naples and Venice as city-states, and as commerce hubs. As a matter of fact just last year I finished a superb set of lectures on Florence, her naval power, and her trade that she should really enjoy.)
Lastly now that my older daughter is working and preparing for college my youngest daughter and I spend much more time together. The other night we were watching Agent Carter together and I was commenting on how much more clever the general level of conversation, formal or colloquial, was back then (in the Forties to early Fifties – language started declining in the mid-Fifties). That the language was snappier and more ironic than it is today, the level of conversation was far more clever, plus it was filled with universal cultural references and idioms.
“But,” I said, “I don’t care much for the décor or architecture of that time period. And I could have never walked around all day in a monkey suit.”
“Dad,” she said, “you must be crazy! I love the décor, the architecture, the clothes, and especially the cars and airplanes from that time period. I love almost everything about the Forties and I’d love to go back and live in that time period, minus, you know, the whole segregation and suppression of women things.”
“Yeah, I guess there is always that,” I said.
“But otherwise the Forties are for me!”
She’s a throwback to my Old Man. He grew up in that time period and always loved it too.
