MEMRESISTOR
Now, change has come in the world of electronics, in the way of a new fundamental quantity.
Basic electronic knowledge (possibly soon to become outdated) posits that there is a trinity of fundamental electronic components, fundametal elements of a passive circuit, namely the resistor, the capacitor and the inductor. These three components are usually juxtaposed (often with helper components) multitudes of ways in various circuits in order to obtain certain varied functions. Three basic components, but about thirty seven (37) years ago, in 1971, an engineer, Leon Chua at the University of California, Berkerly, predicted the existence of a fourth basic electronic component, and he called this a 'memory resistor' or 'memresistor'. He used mathematical formulae and involved equations to show the existence of this element, but at that time, forty years ago, we were comfortable with our three elements, no one was looking to see a fourth one, and electronics had not yet got to its state today - it was not yet the age of nanoelectricity.
Today, we have a group who claim to have discovered this fourth element. Scientists at PC maker Hewlett-Packard led by Stanley Williams have proven that 'memresistance' exists. They have developed a mathematical model and physical example of the memory resistor, which they described in the Science journal Nature. According to Williams, this element is distinct, and no combination of resistor, inductor and capacitor will give you its property.
The memresistor's prorperties are more obvious in nanoscale electronics, one of the reasons why it has remained hidden for so long, the other being the simple reason that no one was looking. talk o the show up in nano.
Williams and his team were working on molecular electronics when they started noticing strange behaviour in their devices. Fortunately, one of the team, Greg Snider had been a follower of Chua's work and this situation, the odd behaviour seemed to tally. Enter the memresistor. Looking through logs of research work, it is evident that many others had discovered such odd behaviour in micromolecules, but no one being the wiser, these had been filed away in the drawer of an irritating headache to be dealt with later.
According to IEEE Spectrum, the magazine of the renowned institute, "The reason that the memresistor is radically different from the other fundamental circuit elements is that, unlike them, it carries a memory of its past. When you turn off the voltage to the circuit, the memresistor still remembers how much was applied before and for how long. That's an effect that can't be duplicated by any circuit combination of resistors, capacitors and inductors, which is why the memresistor qualifies as a fundamental circuit element."
Chua, the one who started this whole memresistance story has called the finding a paradigm shift. He likens the addition of the memresistor to the circuit design arsenal to adding a new element to the periodic table.
For all this to have any value, this property has to have some significant application - and it actually does. Word is already flying around about the computer which will never need to be booted again, a derivative of the memresistance property. The reasoning goes thus: the memory chips of present day computers are volatile. They depend on electric power to retain their information. When this power is off, the information on them wipes away. The memresistor, however, has this inherent property of remembrance. If it is used to make memory chips, they will no longer be dependent on power for their memory. Exit booting of computers. Your computer will always be at the same state where you left it.
Another very important application that has been identified is in the field of neural networks. A neural network is basically a computer system mimicking a human brain: a system of electrical circuits designed to perform in a similar way to the human nervous system. Neural networks address problems that are often difficult for traditional computers to solve, such as speech and pattern recognition. They also provide some insight into the way the human brain works. One of the most significant strengths of neural networks is their ability to learn from a limited set of examples. Neural networks were initially studied by computer and cognitive scientists in the late 1950s and early 1960s in an attempt to model sensory perception in biological organisms. Neural networks have been applied to many problems since they were first introduced, including pattern recognition, handwritten character recognition, speech recognition, financial and economic modeling, and next-generation computing models.
Will the science textbooks a few years from now bear radically different fundamental information? To borrow from Senator Obama's campaign, we shall see over the next few years - rather, we shall keep seeing, as we always have, "The Audacity of Change".

MOTOR PARK BLUES
Lovers have it that quarrels and fallouts strengthen the relationship. One lady even put it to me that a constant happy “at the same level relationship” is tiring and boring and will not stand the test of time. It is true that some partners after a stretch of seemingly equanimous relationship actually act to cause ripples, even if it is in the form of an absolutely unnecessary quarrel. Odd, but true. This applies to all spheres of human existence. I dare-say the human mind thrives on adversity, changes in one way or the other. Had everything been on the same level, with other things being equal, we’d have a swarm of senile, annoying creatures all over the place. This was one of such days that keep the balance.
I can break the causative factors in three, and I will do just this:
- The woman who lost her ticket
- The saucy girl at the park
- The park cleaners
These parts might sound a little strange to all those who don’t have the privilege of moving around in rickety, squeaky old vehicles, otherwise known as public transport, but are sadly confined to a few boring people in a little vehicle. (Ah, now, don’t crucify me! I have the right to a little joy, even if I have to twist my logic a little for the trips). Well, in public transport, for the uneducated, you buy your ticket, get into the bus, and then when everyone is seated, someone from the park comes, collects all the tickets and takes back to some administrator of the park for confirmation before the bus can leave. Now, there are a great many variations to this procedure, and some may not even use tickets at all. I use that description because it was the procedure employed by the transport company in question, and it is most relevant to our discourse.
There was this woman on the bus who could not find her ticket while tickets were being collected. This started the disturbances in the vehicle. Everyone began giving his/her own very right opinion, no matter how ill thought out, as to what course to take, (a Proudly Nigerian trademark, of course), the summary of which is that all these varying opinions end up being vectors that will in summation effect no movement – varying forces, varying directions, moving us nowhere. They only succeeded in heating up the bus. Some folks were wondering why this little ticket was so important to the driver, and why he couldn’t just stop wasting our time and come and drive us away. They wanted him to overlook the ticket issue. Of course, that must have sounded like blasphemy to our driver who had procedures to follow. Some wanted the woman to drop and go sort herself out and quit wasting our time, as it was her fault she lost her ticket. Our woman of course was sitting tight and wouldn’t be budged. Eventually, however, as if in a haze, I noticed our hijacker alighting to go see what could be done. “As in a haze" because some new, fresher attention grabber had emerged, in the form of a young lady, a worker at the park, and of course attentions had switched to this new abnormality.
This is another park specific issue, so let me give that intro for the less privileged। At these public transport parks, passengers on board usually fill out their details in a book – name, phone number, contact, the like. In this park, someone brings the book and passes it around the passengers on board to fill out. On our bus, there was this not bad looking young girl to pass the book around. At that point, some folks had not yet filled out their details, and instead of this girl to appeal to these folks to fill out the book, she began threatening –“if you don’t fill this out, you won’t leave here, I’ll see how you’ll leave”-that’s a transliteration, as she was saying all this in the local language, where, of course it sounds much more saucy. My God, did this inflame the passengers! Who was this to tell us that we would not leave the park? This began another round of chatter and quarrel and banter which would drain me to express properly here. Everyone was shouting, and this lady, safe some few feet away from the bus would not be shouted down. Someone on the bus was threatening that he’d make her lose her job for such insolence, and she, with as much gusto was telling him what he could and could not do, and not surprisingly, what he could do was termed “nothing”. Hilarious, absolutely! You need to be there to have felt the energy. The hubbub from all this had not yet died down when all of a sudden, we saw the driver running around outside the bus with someone holding a raised rake chasing after him. My, what a scene, worthy of a proper circus spot. News filtered through that the driver had inflamed the cleaner by obstructing his path, some trivial issue, and so the comic show had to ensue, and our driver was so unfortunate because he was eventually not facing off against just one cleaner, but against the legions in the park. Little wonder he had to run, as he even had a serious handicap – he was unarmed against armed men – lethal rakes. The better sense of people around calmed the cleaners down and saved our driver from apparent mutilation.
To be continued ...
NEW THINGS
The above is a sort of template for our discourse – new, newer, even newer, never newest -
SHELLFISH (wordplay on SELFISH)
IT’S NOT THEIR FAULT!
In a bus one evening, I observed the goings on. Now, this bus is not your everyday town service bus. It was a bus belonging to one of the state transport services, and it seemed the driver wanted to make some extra buck on the side by doing some town service runs. On a normal day, this kind of bus drier has no conductor, and this one did not, but there happened to be someone he knew on the bus, an obviously street savvy young man from the looks of things. He asked this man to help him collect money on the bus. Unlike your everyday conductor, this man politely asked for money, not trying to raise a hubbub with every passenger. This scenario made me think.
I wondered, why can’t every conductor act like this? Talk to passengers like this? And the answer snapped right back at me – ‘do you think that in these cramped bus conditions, with this thankless job, that you’d get up everyday and keep up the smiling, the politeness, the calmness with each set of people boarding the bus day in, day out?’ the conversation continued in my mind, ‘No! humanly impossible! Except you’re some kind of hardwired android or robot. Look for that kind of service only on an air hostess on a flight, or some conductor on an executive bus, air conditioned, not overcrowded, and where you’re parting with some good money to get to your destination. The truth is you pay for the service you receive!
Now, some dissenting voices may start out now, ‘you have to treat your customers well, …!’ Now, these are the very same ones who with just a little pressure at work would flare up and threaten the equilibrium in a place. Might just be you. Put these people in the shoes of that conductor, and they’ll probably fare a hundred times worse.
This is the problem I always see with Nigerians. So many Nigerians only look at issues as it will benefit them; no one looks at the big picture, cause and effect, parochialism threatens to destroy us. Open up your eyes, your mind and look at the big picture.
Truly I tell you, I do not blame the bus conductor. Circumstances have made it so he has to be hardened to survive his environment, and also the bites of those very customers, who themselves are hardened against him already. It is this eternal search for someone to blame that makes us blame the customer. Can’t you look further and see there are more salient issues to the matter? It is a vicious cycle, and it goes on and on and on. The problem is if you keep looking, the pond gets larger and larger and larger and you can’t find someone to pin down, so why not absolve your mind of that need to blame and carry on with an open mind.
Now, this is definitely extremely difficult, but if people can get to this point, using the case of the bus conductor, we will all find that he will have no one to defend against and his behavior will subsequently moderate. ‘Who will go first?’ we ask. Nobody is ready to give in.
We have been on this theme of the conductor, but this problem shows up in every aspect of our relationships. It is commonplace to hear talk like ‘this lecturer is wicked’ from students, it is common to hear MTN bashing, etc. Everyone sees the problem from somewhere else. I tell you, do not deceive yourself! The basic problem is you! You don’t want to hear that, but solve yourself and you’ll see. Other things will just have to fall in place.
Why is the lecturer wicked? He is wicked because he made sure the students sit comfortably with enough space around each one in the exam hall. Just that. This is a time when the students want to sit all jam-packed, they don’t mind being sardines for the few exam hours. Fifty six people on a desk is the way to go. If this lecturer had done what he was mandated to and reported cheaters to the malpractice board, then he would be the father of the devil. Doesn’t it look all twisted? It’s just reminiscent of the rot, the decay in our society, our highly religious society. Wrong is official right, and vice versa. MTN is bad because they make it difficult to get free airtime. Their cards are not easy to hack ... What kind of twisted logic is that? But that is what flies around. Is it not a sorry situation?
Nigerians seem to face the wrong problem and end up with disastrous results. Now look at yourself, disabuse your mind of other issues that eat up – yes, all that prejudice eats up and gives illnesses - you can build yourself to a level where you don’t have to enter these buses any longer, that problem is gone, or you won’t have to bother that MTN cards are not easy to hack, and that they don’t grace you with free airtime, you’ll comfortably afford to have your phone filled at all times, and even move up to more expensive data plans.
The student who says ‘the lecturer is wicked’ can prepare from the beginning of the semester and be ready for the exams. The need to seat close to someone for purposes of malpractice is obviated. Are these not better alternatives? The petty evils fall to the side and become inconsequential. I do not claim to be insulated from these problems, I do not claim Puritanism. I have failed quite my own share of courses in school, which is really bad, but I did not complain about the lecturer. In fact, I was taking it out on myself for not preparing well. Next time, if you do not want to fail, do what you should before the exam. Conquer yourself and everything else will fall under control.
LIVE - FOR TODAY, OR TOMORROW
Now, being neither a sociology major, nor an anthropologist, not being an academician or some sort of researcher, I’m feeling my way on the presentation of this discourse. It might not have all the structure of a thesis paper, but I will do my utmost to make it concise, logical and of maximum clarity.
A really serious occurrence of this issue is in the world of religion. Various religious groups forfeit certain things generally regarded as ‘pleasures’ with an aim in mind, usually an afterlife in a beautiful state, as the seeming pleasures could hinder attainment of that positive afterlife. This is why we routinely hear phrases such as ‘the pleasures of sin’. The Bible has it like ‘pleasures of sin for a moment’ – the now, today. Specifics, I believe are not really necessary in this case, as it should be all too evident.
Balance seems to be the key to this world – enjoy some today, leave some for tomorrow. Free will means you are free of course to fight it out with yourself, draw your own conclusions.

Well, it's good to feel like that sometimes, even when it's unwarranted. I deleted my show desktop icon, and just now saw how to restore it on tipmonkies. Was I happy! Well, it's back there now. I also saw the keyboard short cut. logo key + D. Everybody knows we're talking windows here. Must ave come across it before but, somehow went pop.
Thinking. It seems better to put up smaller posts basically for readability. Better that way. no?
Excuse to stop here.
