Age-Old Logic

When my present research is over, there will be no more aging.

Obviously I am not proposing stopping people from growing old. We’ll always have older people around, driving slowly in the left lane with the blinker on, saying completely inappropriate things in loud voices, and telling the rest of us that we don’t call home often enough.

But what I can and will change is our age.

Time marches on, minute by minute, day by day, and year by year. Even when it seems like time is standing still, like when you’re in line at the bank counter or you’re sitting next to someone on the train that’s talking on a mobile phone in tedious detail about every one of her children.

Even then, time is racing by, pushing us further toward the cliff of our existence into the chasm of our not. And as the years roll by, they add to our age, one by one. Another birthday cake eaten, another year gone.

Some try to cheat the system by simply telling people the wrong number for their age. But everyone knows. And it's rather sad.

But there’s a better way. Why change the number when we can change the number system?

For millennia, humans have used the decimal system, in base 10.

I suppose this came from our having ten fingers available, but that makes it a cruel joke that we’re taught not to count on our fingers in school.

But haven’t we lived with that system long enough? Don’t you think we’ve gotten smarter in the last couple thousand years?

Did Plato have reality TV? No, he just had reality.

Did Copernicus have the internet? Of course not; he just had the galaxy.

Did Benjamin Franklin have glasses? Well, yes, but they probably looked a lot dumber than today’s designer glasses and certainly cost far less.

And he certainly didn’t have contact lenses that he could lose, tear, and have to replace every few days.

So isn’t it time that we had a shiny new number system, too?

In fact, we should have several to represent the fact that our society is complex, diverse, and horribly bad at math.

My research concludes that, our age can be kept artificially low by increasing the base that we count in.

For example, if you are about to enter your 40th year, then you might tell people, truthfully, that you are 37 (in base 11). Or if you are feeling particularly spritely, you can tell them that you’re having your 28th birthday (in base 16).

Or if you’re feeling young and completely nerdy, you can say that you’re 2A (in base 15).

The system also works in reverse. If you’re only 14 and you feel you really really need that six-pack of beer, then you can tell the clerk at the 'Modern Wines' that you’re 22 (in base 6).

No longer will people have to construct elaborate and pathetic lies about their age; they can simply tell the truth while using the power of Math.

Remember: It’s not how old you are, but how old you feel...

hoping for the best is to realistically consider the worst..

Some doctors will predict the worst possible outcome for their patients.

Whenever I go to my doctor, I try to envision the worst-case scenario for my latest injury. For a neck issue, I went with paralysis.

For my shoulder, I opted for amputation. And I make a habit of telling my doctor that I’ll see her the next time my body falls apart, unless I’m dead.

My doctor seems to find these predictions alarming and rushes to assure me that the surgeon is not going to amputate, or that my cold is not lethal. But I find it comforting to know the worst that can happen and to verbalize it.

Sure, I probably just have a sore throat - but what if it's an early indicator of Bubonic Plague? Or what if that slight headache really is a brain tumor?

The optimist would say that you should look on the bright side. See the positive aspects of any situation and hope for the best. I do consider myself an optimist. To me, the glass is always half full. But I wouldn't drink it because it could be laced with cyanide.

My method of hoping for the best is to realistically consider the worst. Then things can only get better from there. And if things are as bad as I predict, I have the satisfaction of being right, which always feels good.

For example, maybe amputation is an extreme outcome for a sore shoulder. But what if the injury takes a long time to heal? Or what if it requires surgery, which can have risks and complications?

These would be unfortunate to one simply hoping for the best. But in my world, they’re not so bad compared to hauling out the bone saw and hacking off the limb.

With me, doctors will clearly outline the bleakest possibilities for patients. For example, doctor might say, “You appear to have a cough, Mr. Naik. This may just be the cold that is going around, but it could also be the beginning stages of any number of terminal diseases.

You should put your affairs in order just in case. See you next time, unless you’re dead.

Sure, these consultations might be a bit of a shock at first. But imagine, after each illness recedes, how wonderful you’ll feel just to be alive.

Until the last one, of course. Your doctor will eventually be right about the worst case scenario, which will give them that satisfying "I told you so" feeling.

That'll be nice for them.

Doomsday.... and am really excited..

Apparently, the world is coming to an end today.

And I’d just gotten used to the place. It seems worth spending a few minutes preparing ourselves.

I mean, the world only ends once.

Here are some tips for how to deal with "The End":

• Brush your teeth. There’s nothing like starting on a long journey and realizing your breath stinks. And who knows when you’ll see a tube of Crest again?


• Put a lot of food out for the dog. Hell, just open the rest of the bag out onto the floor. We’re going to be gone for a while.


• Make sure the stove and coffee pot are turned off. Check them twice. Three times. You don’t want to worry about that for the rest of eternity.


• Bring comfy shoes: We always want to look our best, but nobody looks good when they’re hobbling along for miles because of the blisters. And you don’t want to break a heel in all the kerfuffle.


• Pack light: The holy book has never been clear on the baggage rules. Will we be able to check bags? Does the first bag cost $25? Is there enough room in the overhead, or do we have to take up precious leg room for our carry-ons? Better to pack light and avoid the hassle.


• Leave the parka at home and bring a windbreaker instead.


• Take those pills: We don’t know what the travel accommodations will be like, so if you’re at all prone to motion sickness, it’s best take your pills in the morning. Besides, they might help you sleep. It could be a long journey


• Bring something to read. Long flights with no entertainment are so tedious; don’t risk it.


• List your accomplishments: Just in case there’s an opportunity for an upgrade, you might want to list out all of the good things you’ve done in your life. Just for a reminder (they probably know already). If they do have a rewards program, these will probably be your points. And you don’t want to travel in coach if you don’t have to.


• Get some good sleep the night before. It's always more fun to travel when you're well-rested.


• Lock your door and sit on the curb. Like the stove, don’t wonder whether you remember to lock it. And go outside to sit on the curb and wait. Wouldn’t it be embarrassing if they stopped by to get you and you didn’t hear them because you were in the bathroom? Don’t run that risk.

That's all I can think of.

I need to go check the stove and coffee pot.

See you tomorrow....

red wine makes a metal compound superconductive.... I knew it

Yoshihiko Takano (R), professor of Japan’s National Institute for Material Science and researcher Keita Deguchi (L) display a superconductive metal compound, which is seven times higher when dipped in red wine than for ethanol or water at his laboratory in Tsukuba city, suburban Tokyo on March 10, 2011. – AFP Photo

TSUKUBA: Japanese scientists at a boozy office party stumbled across a discovery they hope will help revolutionise efficient energy transmission one day: red wine makes a metal compound superconductive.

The researchers plan to showcase their surprise findings later this year, the 100th anniversary of the discovery of the phenomenon of superconductivity, the zero-loss flow of electricity through certain materials.

The “eureka” moment came when National Institute for Materials Science researchers found that an iron-based compound became superconductive after being soaked in alcoholic drinks such as beer, wine and sake.

Red wine was the hands-down winner in producing the desired physical effect, although no-one is quite clear yet on how exactly it worked, said researchers at the institute in Tsukuba, east of Tokyo.

The ratio at which compounds became superconductive was seven times higher when dipped in red wine than for ethanol or water. It was four times higher for white wine and three times higher for beer, sake and whisky.

“The better it tastes, the more effective it is,” the institute’s lead researcher Yoshihiko Takano said, while allowing that taste is subjective.

“There may be a connection between the substance we humans sense as a taste and the substance that induces superconductivity.”

“It is as if a detective was tracking down the culprit in a suspense story — the guy is in the glass, but we still don’t know if he is acting alone or conspiring with others.”

The team hopes the find will help in the quest to one day unleash the potential of superconductivity to build power infrastructure that reduces energy use and mankind’s reliance on climate-changing fossil fuels.

When an electric current passes through a conductor such as copper and silver, part of the charge is lost as heat, a loss that increases with the distance the charge travels.In superconductivity — first discovered in mercury in 1911 — electrical resistance suddenly drops to zero in some metals when they are cooled to near absolute zero (-273 degrees Celsius, -459 Fahrenheit).

This also produces a strong magnetic field — an effect which has found applications, including in MRI body scanners.

To achieve zero-loss power transmission now, cables encased in tubes can be cooled with liquid nitrogen to make them superconductive — but the complex and expensive technology has not been commercially used on a large scale. Power companies have run only small-scale and pilot projects.

The dream is, however, to one day find materials that can become superconductors at room temperature, which would allow zero-loss transmission of power over vast distances.

“This may sound like the stuff of dreams, but electricity generated by solar power in the Gobi desert (of China and Mongolia) could be transported to the other side of the globe,” said Takano.

“The sun is always shining somewhere on Earth, and the dream is for electricity to be transported to far-away places with no power loss.

“Imagine there is a ring of superconductive cables along the equator with solar cells attached at certain places. If there were branches, clean electricity could be dispatched to the remotest rural areas.” Mamoru Mohri, a former astronaut who heads the National Museum of Emerging Science and Innovation in Tokyo, said advances in superconductivity could ring in “an era in which we don’t have to burn as much fossil fuel”.

Takano’s team made their discovery when they put tablets of an iron-based compound called Fe(Te,S) into alcoholic drinks at an office party a year ago.

The team found that after being soaked for 24 hours in red wine or other alcoholic beverages, the compound became superconductive when cooled to about minus 265 degrees Celcius (minus 445 Fahrenheit).

Takano plans to present his findings at a European conference in September in The Hague, near Leiden where Heike Kamerlingh Onnes discovered superconductivity 100 years ago.

Reiji Ogino, power-industry analyst at Mitsubishi UFJ Morgan Stanley Securities, said the hunt for new electricity transmission methods has sped up as the world looks to reduce carbon dioxide emissions.

“I’m looking forward to seeing a technical breakthrough,” Ogino said — but he cautioned that it remains unclear how much it would cost to replace existing transmission networks.

Tomoaki Fujii, who heads equity research at Morningstar Japan, said superconductivity is “a technology with high expectations”, but said that it is “a bit too early” to start buying related stocks just now.

“We haven’t seen superconductivity used for electricity transmission even 100 years after it was discovered,” he said. “And we would have to see how smoothly it could actually be utilised”.

The mystery of antioxidants...

A young lady just rang to ask if I was interested in antioxidants.

“Passionately,” I said, and she told me she was happy to hear it, because she
wanted to tell me about the antioxidants in Nescafé.

“We hear a lot about the benefits of antioxidants these days,” I ruminated, “but there is nobody speaking up for the oxidants. We would, after all, have no need for antioxidants if there were no oxidants, an indisputable fact for which I have always felt that oxidants never receive the credit they deserve.”

“Be that as it may,” she said, “most people do not realise the antioxidant
benefit of coffee in general and Nescafé in particular and...”

But before she could continue, I found myself interrupting somewhat ungallantly, with a thought that had suddenly occurred to me: “If coffee contains antioxidants, does instant coffee contain instant antioxidants?” I asked. “If it doesn’t, I fear it could lead to you making and drinking the coffee before the antioxidants arrive, leaving them turning up late when the cup is empty and being flushed away with the washing up.”

“I’m sure that doesn’t happen,” she said. “In fact, the benefits of the
antioxidants in Nescafé...”

But my mind was becoming absorbed with a topic I had introduced earlier. “It’s a bit like antibiotics and probiotics, I suppose,” I said.

“I remember a couple of years ago when several probiotic foods appeared on the market, the antibiotics were furious. ‘We are performing a valuable function fighting disease’, they said, ‘and our biotic opponents ought not to be allowed to call in a mercenary force of probiotics to support them.’

Outright war was only averted when a probiotic spokesorganism came up with
a peace plan involving the partition of the biotic empire into separate regions
of influence for the antibiotic and probiotic movements.

Of course, if the antioxidants were to join forces with the antibiotics, it could force the oxidants into an alliance with the probiotics, leading to a drastic increase in tension.”

“I hadn’t thought of it like that,” my caller replied, “but I am sure that drinking a cup of...”

“And where, we must ask ourselves,” I interrupted again, “do the antiperspirants fit into all this?

Given the potential power of the antibiotic and antioxidant alliance, they would find it hard not to sign up for a grand, anti-everything league, finally giving up the position of neutrality they have held for so long, thanks to there being nobody specifically marketing perspirants as such.

Come to think of it, with the antibiotic and antioxidant alliance calling themselves the AAA, as they surely will, this seems bound to drive the other AAA, the Amateur Athletic Association, into the arms of the probiotics and oxidants, and since athletics is a highly effective way of producing perspiration, that makes it even more likely the antiperspirants will join the other antis.

Very worrying. I think “I need a cup of coffee.”

“Antioxidant Nescafé?” she offered.

“No,” I said: “I hate instant coffee.” And we left it at that.

Why is India still Turbans & Camels?

Most books on India have a disproportionate number of pictures and stories from Rajasthan.

To outsiders, the idyllic world of camels, cows, colourful saris and handle-bar moustaches seems to convey a more authentic feel that the rest of homogenized India.

While relative proximity to the nation's capital has helped, I feel that the Rajasthan theme is rather overworked and it is time that writers and cameras moved on. Simply being drawn to the visual appeal of Rajasthan is rather superficial.

To me, local culture in other regions is equally rich. Reflecting on William Dalrymple's essay on the oral tradition of Rajasthan titled "Homer In India" (The New Yorker, Nov 20, 2006, Issue 38), I feel I might need to alter this view.

A young Harvard classicist named Milman Parry had a brilliant theory that Homer's works, the foundation upon which all subsequent European literature rested, must have originally been oral poems, and that they contained certain recurring formulas that he thought were a product of traditions of oral transmission.

He believed that to study Homer properly you had first to understand how oral poetry worked, and that since Yugoslavia was the place in Europe where such traditions had best survived he caught a ship to Yugoslavia in 1933 to prove it in the field. Parry was described as a sort of "the Darwin of oral literature".

He writes:

While I was staying at Rohet, I heard about what seemed to be the most remarkable survival of all: the existence of several orally transmitted epic poems. Unlike the ancient epics of Europe--the Iliad, the Odyssey, Beowulf, and the Nibelungenlied (the basis of Wagner's "Ring Cycle")--which were now the province only of academics and literature classes, the epics of Rajasthan were still very much alive.

They were preserved by a caste of wandering bhopas--shamans and bards--who travelled from village to village, staging performances.

It is perversity that the most backward, conservative regions are often culturally the richest? More than any other part of the country, large chunks of Rajasthan remained under the authority of the local hereditary rulers. It was only after the abolition of the privy-purses in 1971 (Thanks to Indira Gandhi) that the age-old feudal structure started to really erode. This raises a difficult moral question.

Moreover, the Gujars are very often illiterate, and illiteracy seems an essential condition for preserving the performance of an oral epic. It was the ability of the bard to read, rather than changes in the tastes of his audience, that sounded the death knell for the oral tradition. Just as the blind can develop a heightened sense of hearing, smell, and touch to compensate for their loss of vision, so it seems that the illiterate have a capacity to remember in a way that the literate simply do not.

This was certainly the conclusion of the Indian folklorist Komal Kothari. In the nineteen-fifties, Kothari came up with the idea of sending one of his principal sources, a singer from the Langa caste named Lakha, to adult-education classes.

The idea was that he would learn to read and write, thus making it easier to collect the many songs he had preserved. Soon Kothari noticed that Lakha needed to consult his diary before he began to sing. Yet the rest of the Langa singers were able to remember hundreds of songs--an ability that Lakha had somehow begun to lose as he slowly learned to write.

In the Yugoslavian case the recordings survived, but the actual oral tradition did not. Death of oral tradition takes along with it an entire subset of culture, leaving behind only a skeleton of words preserved in mummified form on CDs.

Sad, but can it be preserved in a living form? If it can, then what about the moral implications as suggested above?

I agree that it is a bit of a leap to generalize from oral tradition to culture in general; but, are more developed regions of India culturally shallower than more backward regions like Rajasthan?

Local culture in other regions are equally rich, but not as well preserved. If so, then I should not begrude Rajasthan's pre-eminent position on the covers of those books.

When I read about traditions dying, I feel that I am personally responsible in a way.
Yet, culturally we are relatively better off as this paragraph from the essay suggests,

Anthony Lane noted in this magazine in 2001, in the aftermath of the attacks on the United States, that the people of New York again and again compared what had happened to them to films: "It was like 'Independence Day' "; "It was like 'Die Hard' "; "No, 'Die Hard 2.' " In contrast, when the tsunami struck at the end of 2004, Indians were able to reach for a more sustaining narrative than disaster movies: the catastrophic calamities and floods that fill the Mahabharata and the Hindu tradition in general.

But then, we might have much more to lose too.

Signal acquisition module targets audio and vibration testing

Hot swappable 2-channel 2-wire multiplexer with bus buffers

Linear Technology’s LTC4312 is a hot-swappable 2-channel 2-wire bus multiplexer that allows one upstream bus to connect to any combination of downstream busses or channels. An individual enable pin controls each connection.

The LTC4312 provides bidirectional buffering, keeping the upstream bus capacitance isolated from the downstream bus capacitances. The high noise margin allows the LTC4312 to be interoperable with I2C devices that drive a high VOL (> 0.4V).

The LTC4312 supports level translation between 1.5V, 1.8V, 2.5V, 3.3V and 5V busses. The hot-swappable nature of the LTC4312 allows I/O card insertion into, and removal from, a live backplane without corruption of the data and clock busses.

If both data and clock are not simultaneously high at least once in 45ms and DISCEN is high, a FAULT signal is generated indicating a stuck bus low condition, the input is disconnected from each enabled output channel and up to 16 clocks are generated on the enabled downstream busses.

A three state ACC pin enables input and output side rise time accelerators of varying strengths and sets the VIL, RISING voltage.

Upper Airway Stimulation device offers hope for sleep apnea sufferers

Loud snoring is not just a tiring irritation for partners but can also be a sign of sleep apnea.

The National Institutes of Health reports that more than 12 million Americans suffer from the most common of the three varieties – obstructive sleep apnea, where the upper airway is repeatedly blocked during sleep.

There are a number of treatment options already available and Minneapolis-based Inspire Medical Systems is about to add a shocking new addition to the treatment options on offer.

The new system – which is about to enter clinical trials – electrically stimulates the nerve at the base of the tongue to keep it from blocking the air's journey to and from the lungs, and so offers the patient a good night's sleep.

An apneic can experience a cessation of airflow for more than ten seconds, but is generally partly awoken to take a breath. Even so, this lack of sound sleep can lead to other problems.

Persistent oxygen starvation often results in daytime fatigue, lack of concentration and decreased alertness and can go on to increase the risk of heart attack and stroke. Depression, muscle pain, inefficient metabolism, diabetes, impotence and a host of other ailments are also associated with sleep apnea.

One of the main causes of the most common variety of the condition – obstructive sleep apnea – is caused by the tongue and throat muscles becoming too relaxed and blocking the airway. Most sufferers are treated using a system known as continuous positive airway pressure (CPAP), where air is blown through the nose throughout the night and which can be very effective if used all the time.

But such a system is not for everyone and studies have shown that the technique is often abandoned by a significant percentage of sufferers.

Using well-established technologies from the fields of cardiac pacing and neurostimulation, Inspire Medical Systems has developed a system specifically to help those who are plagued by that troublesome tongue. The Upper Airway Stimulation (UAS) therapy designed by Inspire Medical Systems stimulates the nerve that controls the base of the tongue with a small electrical pulse during sleep, to keep it toned and in place.

A pacemaker-like device is implanted under the skin, near the collarbone, and a wire is fed to the problematic twelfth cranial nerve. A sensor detects when the sufferer takes a breath and instructs the implant to stimulate the nerve.

The system is adjusted so that the tongue receives just enough current to keep it from blocking the airway but not enough to disturb sleep (or result in any rude mid-snooze gestures) and a remote allows the patient to activate and deactivate the system. A timer can also be set so that the zapping is delayed until after the user is asleep.

Inspire Medical Systems' hypoglossal nerve stimulation technology has just recently been given the all-clear for Stimulation Therapy for Apnea Reduction pivotal clinical trials by the U.S. Food and Drug Administration (FDA) and will soon be heading to key sites throughout the U.S. and Europe.

However, sufferers reading this might like to note that only those who tick all of the right boxes will be accepted into the trial, so cases where some other tissue causes the problem will not make it through. The results of the study will form the basis of a pre-market approval application to the FDA.

Haptic exciters simulate mechanical key movement and act as audio drivers

HiWave Technologies PLC (formerly known as NXT), a provider of electronics solutions for audio and haptics, has announced combined haptic touch and audio exciters for touch panels and screens used in industrial, home automation, automotive and consumer electronic products.

Applications include pad computers, hand-held and integrated displays and controllers.

When used with HiWave driver modules, a pair of NXHX14C exciters disperses bending waves evenly over the surface of touch panels so that users experience the sensation of depressing mechanical keys when they touch the panel surface.

The simulated mechanical movement enhances the human interface, enabling faster and more accurate keystrokes.

The same transducers also convert the touch screen into a flat panel loudspeaker with nominally flat response from 200 Hz to 15 kHz.

This eliminates the need for separate loudspeakers and amplifiers, enabling more compact products with fewer components. It also reduces bill of materials and manufacturing costs.

The exciters are designed for use with touch screens up to 19” and are available in 1-W and 2-W (RMS) versions with nominal drive impedances of 4, 8, 16 or 32 ohms.

Each exciter consists of a 14-mm diameter voice coil mounted on plastic suspension. Overall height is just 11 mm.
