Interesting development.

From BBC News:

Motion-sensitive laptop developed

A motion-sensitive laptop which can be controlled much like a Nintendo Wii remote is under development.

The tablet PC laptop has been adapted to respond to a user when moving the machine up or down, side to side, or forwards and backwards.

It is hoped the BT Balance system can help people with disabilities or the elderly, for whom using a keyboard or mouse can be difficult.

The technology is under development at BT’s research labs in Ipswich….

Adam Oliver, head of BT Retail’s age and disability research, said it could be useful for “someone needing to use their laptop in conditions where trying to type or manipulate a tiny keyboard is tricky or where they are unable to use both hands”.

He added: “It could even be for someone just using their laptop on a crowded train.”

There are essentially two components to BT Balance – a microchip called an accelerometer, which works in much the same way as the balance system in the human ear, and a software interface which interprets the motion data.

The accelerometer is a machine on a chip, known as a Micro Electro Mechanical System (MEMs), which works by detecting changes in the acceleration and gravity of an object compared to the static gravity field of the earth.

What is interesting is how the chip works. The article says:

By measuring the amount of static acceleration due to gravity, the chip knows the angle a device is being tilted at with respect to the earth. By sensing the amount of dynamic acceleration, it can calculate the direction the device is moving.

Accelerometers are used in cars to detect when to inflate an airbag, in devices like the Nintendo Wii controller and in Apple laptops to detect if the computer is being dropped.

With that in mind, I can see a cool direction for some science fiction! It would explain air scooters, for example. It could even stretch to include mind control over objects such as unmanned recon planes or even missiles. Cool.

Stephen Hawking Flies into Zero-G and “Tastes” Space

By A.J.S. Rayl
April 27, 2007

British theoretical physicist Stephen Hawking – whose groundbreaking work on black holes and the origins of the universe has rewritten physics – floated free of his wheelchair in zero-gravity yesterday. Flying onboard a commercial 727 jet especially converted for weightless flights, he experienced for the first time what astronauts-in-training experience on NASA’s KC-135, better known as the “Vomit Comet.”

Hawking, 65, perhaps the most renowned theoretical physicist of his time, has long suffered from a motor neuron disorder called amyotrophic lateral sclerosis (ALS), better known as Lou Gehrig’s disease. Unable to move his hands and legs, he has been wheelchair bound for nearly four decades. In the mid-1980s, he also lost his ability to speak naturally after a tracheotomy following a bad bout with pneumonia….

Yesterday, Hawking escaped the confines of his illness for 4 minutes and experienced a freedom unlike any he’s ever known, becoming the first person with a disability to experience a zero-g flight on this commercial airline.

Before taking off over the Atlantic Ocean, Hawking acknowledged that experiencing weightlessness even for a few seconds would be a welcome change from life in the wheelchair. “The chance to float free in zero-g will be wonderful,” he said through his computer voice synthesizer during a pre-flight news conference. “I want to demonstrate to the public that anybody can participate in this type of weightless experience.”….

Hawking, who was accompanied on his flight by physicians and nurses, announced the plans for this flight earlier this year at his 65th birthday celebration on January 8 in Cambridge, England. Beyond the fun of floating free, he is preparing for a sub-orbital spaceflight on Virgin Galactica, the “spaceline” offshoot of Virgin Airways, slated to begin launches in 2009. Virgin’s founder, billionaire Richard Branson, said he will cover the $200,000 tab for the flight into space.

It must have been one helluva experience for Hawking. I’d do it, if given the chance. To be completely non-weight bearing? Hell yeah I’d do it.

The article also describes the parabolic flight very well. It also has info on the company (Zero Gravity Corporation) that has made the civilian version of NASA’s “Vomit Comet”.

No, not that moron, Shrub. There’s no home there. But for Lonesome George, a Galapagos tortoise.

From BBC News:

Lone tortoise ‘not last of kind’
By Paul Rincon
Science Reporter, BBC News

The giant Galapagos tortoise that became a conservation icon when it appeared he was the last of his kind is not so alone after all.

“Lonesome George” was thought to be the only survivor of a tortoise species native to the isle of Pinta.

Now, the journal Current Biology reports the discovery of a hybrid – the offspring from the union of a Pinta tortoise and another island species.

The “new” animal thus shares about half its genes in common with George.

Unfortunately for efforts to get George to reproduce, this hybrid tortoise, recently found on Isabela isle, is also a male.

Nonetheless, its discovery in a relatively small sample of tortoises raises fresh hope for the future of George’s species (Geochelone abingdoni).

A more thorough sampling of the 2,000 tortoises living on Isabela could yet reveal a genetically pure Pinta tortoise, say the researchers….

Researchers took DNA samples from 89 of these animals and compared their genetic codes with those of other tortoises from the Galapagos that are held in a database.

The database includes DNA from six G. abingdoni specimens held in museums, and Lonesome George.

Genetic analysis revealed that one tortoise sampled on Isabela Island is clearly a first-generation hybrid between native tortoises from the islands of Isabela and Pinta.

“It’s extraordinary. I, and everyone involved with George, always imagined that something like this could happen, but never thought it would,” said Henry Nicholls, who has written a biography of the octogenarian tortoise called Lonesome George: The Life and Loves of a Conservation Icon.

“It is surprising to find a hybrid on Isabela. It raises questions about how it got there,” he told the BBC News website.

I’d like to read that book. Cool title.

With the diverticulitis bout lessening, I am considering, gulp, going healthy.

Anyone try those V8 Fusion drinks? I figure if I sneak the good food into me without me knowing it, I’d be able to make a good start.

I went to see a doc today. Dropped one of the antibiotics and continuing the other. I’ll also see a gut doc and get a colonoscopy done. The best thing about that test is I’ll be unconscious. That’s the only way I’d do it anyway. The really bad news is that I can’t have any sesame seeds, popcorn, or rough stuff. I can have veggies, which is roughage, but no rough stuff. No popcorn? Bummer! Then again, at least he didn’t say no chocolate, although I am no-dairy for a while.

Thank God.

Okay, the vacation started out rocky to begin with.

One of the cats got ill right before we were to leave so we had to put it off a day. Pav spent the all trip at the vet’s. That’s a story for later.

We finally left 1pm Wednesday. It promptly started raining until we were about four hours into the trip.

I was only able to drive for two hours before I was done. My body just can’t do it anymore, dammit. We didn’t even make the trip in one day. We were both so exhausted. The hotel we stayed in was awful. It’s off of exit 205 on Interstate 81. Big name but big suckage.

The rain that we had left behind on day one caught up to us for most of the second day, much to our joy. (insert sarcasm) We got to Lorna’s mom’s place in Boyertown, PA without any more adventures, though.

I stayed there one night and headed to Jersey on Friday, saw Kelli test for and get her first degree black belt. I can’t remember the name of the style they follow but I call it Moo Shoo Duck since it has Moo Duk in it. Anyway, saw Kelli get her belt then went out to a celebratory dinner at a place called Prospector’s. Decent place.

I wasn’t feeling well (truck lag?) and had bourbon salmon. Not bad, but didn’t taste any bourbon. And yes, it was cooked thoroughly. After that, we ran some errands and returned to my brother’s house. I really love my niece and nephew and I had a lot of fun with them. Ryan and I played some Xbox games. Ghost Recon (?) and some sort of race car thing. Kelli had her cousin over so I didn’t see much of her while the cuz was there.

I still wasn’t feeling well but I ate two slices of pizza and, later, some ice cream cake. Ryan and I stayed up late playing with the Xbox and on the computer.

When I woke up Sunday, I felt like crap. What I had to eat the day before violently exited the opposite end. I lay on Kelli’s bed while she told me the names of all her stuffed animals (and she has a lot). I felt so lousy that I had my bro test my blood sugar in case I was crashing from the cake the night before. Nope, ’twas fine. I was supposed to go visit Mom but I just kept feeling worse as the day went on. Finally, when they left for Mom’s, I left for PA and Lorna. All I could think of was getting to Lorna. I feel bad that I didn’t see Mom. I normally would have gone to her and had her fix me but my step-Dad’s brother was in town too and they were having this gathering. I did NOT want to hang with strangers while I moaned, groaned, and pooped my brains out.

The trip back to Boyertown from Riverside took much longer than it should. I pulled over at a rest area off the turnpike and slept for about 45 minutes. Then I continued on. I got to Boyertown, caught Lorna up on the black belt thing and bits of the trip, then I went to bed. I got up a few hours later and hurled what little was in my stomach.

We went to the doc Monday (yes, I was feeling that bad) and he confirmed what we were afraid of: another bout of diverticulitis. And a bad one. He prescribed liquid diet and two antibiotics.

Tuesday morning, Lorna says she’s not feeling well and then she gets sick too. We think it was either a 24hr bug or a combination of too much licorice and bad Lebanon bologna. By Wednesday morning she is feeling mostly better and we finally leave Boyertown Wednesday afternoon, drive until 7ish, stay overnight, then continue the drive today.

Lorna’s feeling better, although wiped out, but I’m still puny. I managed to eat a baked potato a short while ago so if it stays in, I’ll be able to eat more tomorrow. This morning we stopped at Cracker Barrel where I had some cereal and banana. It didn’t stay put very well, though.

The dogs are thrilled we are home. Sam is in Lorna’s lap in the recliner. The others are stretched out around us. Jo and PopCorn are on the bed, declaring they are Queens of the House. My fish are doing great, although I see less shrimp, I think.

And so, we are home, at last.

bookmark_borderMother Tree, Part 7

(a bit of the manuscript was clipped ’cause it stank)

“I’m afraid of the dark.” One child spoke, her voice quivering.

“Why?” The priest asked her.

“I don’t know what is out there.”

“Ah. I will tell you what is out there and tomorrow you will see it. There is nothing to be afraid of, nothing at all. We are inside a circle of tall stones, each of them at least twice my height. Where we are is dirt and grass but where the stones sit is a circle of rock underneath them. This is sacred place from a long time ago.

“The stones are gray and silver and some black, swirled together. None of them have moss although they are weathered by the world as it passed them by. Once there were words and drawings on them but they cannot be seen anymore. Those words and drawings were for the people of that time, not this one.

“Beyond the stones are trees almost as old as the Mother Tree herself. They are tall and proud, almost too proud at times. Some of the trees have grown together to form what looks to be one tree, but it is not. After the Mother Tree chose her first two priests, she told the trees here to make her a temple.

“Five trees leaned toward each other, their branches and trunks entertwining. The Temple to the Mother Tree is made from those trees. The Temple is alive and we must treat it as such. Other trees leaned together so their branches formed a ceiling over an area where the priests live. No rain or snow falls on the ground they protect, even now. Yet still more trees adjusted themselves over the years to provide sunlight where it was needed to allow the priests’ crops to grow.

“All of this is to our right and behind us. In front of us is another clearing, quite large. This is where a village once stood and now will stand again. That is where you will make your new homes. So there is nothing to be afraid of, children, for the trees are commanded by the Mother Tree herself to protect and take care of you.”

As the priest had spoke, most of the children lay down and fell asleep. By the time he was finished, only the young carpenter was awake. “Is it true? Did the trees actually move themselves to form the Temple?”

“It is true. In the morning you will see for yourself.”

“Uncle, I am a carpenter. I use wood for my craft. How am I to do this here? I would feel as if I am murdering the relatives of my protectors.”

“Beyond these trees is the usual forest. There are wind felled trees as well as branches and trunks broken during the winter. Those are what we use. To return to the earth, they feed the other trees. To be used by the priests is to serve the Tree. Either way, they do not mind in the least.”

“I see. Still, I feel as if the trees are watching me, as if they know the names of every tree I have helped cut down.”

“They may be watching you, yes, because they can sense what your trade is. But the trees you cut down did not have names. They had no spirit in them and therefore were not truly alive. Not all trees have a spirit, a sense of self. The closer to the Mother Tree, the more that do.”

The young man was silent. “So just as one tree is harder than another, so can one tree have a spirit and another not. I will sleep on this, Uncle.”

“That is not difficult, Nephew. I am old. I need assistance with the upkeep of the Temple. The Mother Tree only accepts children as her keepers.”

“How many did you see in your dream?”

“I did not count them. Perhaps there were twelve. Perhaps less, perhaps more.”

The villagers murmured amongst themselves after the announcement. To the side sat the scions. There were twenty of them, two of which would be of the age of consent within a season. The two older boys would be given the choice to stay with their village or go with the priest. The villages’ elders would also have the choice about the others.

“We do not want to give up the orphans for the sole reason they are a burden. They are not. They are as loved as any child.”

“Some villages are burdened. The harvest has been too small. The game animals are leaving to find better food themselves.”

“Our village has five orphans due to the illness last spring. We are short on those old enough to help with the harvest yet have many to feed.”

When they were done, fifteen of the orphans would go with the priest. Some villagers were crying, others were emotionless. Some seemed relieved.

The elder left the priest’s tent and went for a walk alone. He thought of the villagers left at home. Most of them were either too old to make the trip or unmarried. Every child had been brought to the presence of the Mother Tree. He turned and walked toward the group of tents from his own village. As he approached, he heard the sound of children laughing. He changed his direction to go see.

He found a large group of children playing the game of Hunt and Prey. Some ran low, others ran and leaped about. Others remained in place, reaching out to grab someone as they went by. It was a game that built strength and encouraged group thinking.

He saw that all the children bore the mark of their village. Did the priest’s dream meant they were to lose all the children? His heart skipped a beat at the thought of any village without the sound of children playing. He continued to watch, trying to understand what the dream meant. He watched a boy run fast and leap over a log. He was the grandson of another elder. He not only wore the mark of the village, but the mark of his family. Both were embroidered bands of cloth around the thigh. When the child reached the age of consent, the cloth would be exchanged for a tattoo, his first of many.

He watched the boy who was the hunter after the other. He didn’t leap over the log but ran around it. He cut across the circle, always staying close to his prey. The elder watched the boys’ legs as they ran. Then he saw it. The hunter wore only one mark: the one of his village. He didn’t wear one for his family. The elder stood straight and looked at everyone’s legs. Most wore two, but there were some that wore only the mark of their village.

Scions, the orphans of the villages. Lacking any family, not even a distant cousin claim them, they were children who had no family tree. The village was the rootstock to which they would be grafted.

Scions were taken care of by their village and lived in a communal hut or lodge. Each family was obligated to donate food from their own supply; the more scions a village had, the harder it was for the village as a whole.

Food had been scarce in the past several years. It was why there had been only seven children for the ritual. If the priest took some of the orphans, the burden would be less for each village and there would be more food for each family and more to put into storage for the harsh winters.

But the secret of the sacrifice—the fact that no child was actually killed—needed to remain a secret. So how to explain the scions’ departure with the priest?

“Nephew, I had a dream last night.”

“Was it a good dream, Uncle?” The elder sat on the dirt in front of the priest.

“I do not know. Let me tell it to you. I think you can help me with it.” In the priest’s arms lay one of the babies. She drank from a leather teat, her little hands clutching it. The other lay nearby, playing with the fringe from his leather vest.

“In my dream, I returned to the Temple to find a village of tents. Everyone was young, from these infants to as old as just starting a beard. Each had the markings of their home village, and there were many represented. They were building a new lodge from wood from the Mother Tree. They were laughing and playing as they worked. Older ones were up high while the younger ones were down low. They took turns watching over those too young to help. Once the village was built, we all went to the Mother, who accepted the blood of everyone and everyone changed their village markings to one similar to the mark of the Temple.”

“Has their never been a village around the Temple before?”

“Not in many lifetimes. We sometimes found the stones of a foundation.”

“And everyone was children?”

“Yes. Some were just reaching the age of consent.”

“I do not understand how I can help you with this.”

The priest shifted the baby to his shoulder where he began patting her back. “Do you not know of a group of such children and youth?”

“With the markings of all the different villages? No, I do not.”

“Go and think on it.”
