Model railroad museum

I visited the SD model railroad museum to begin my new year. The museum has elaborate models of rails set within the industrialized settings of early 20th century. What I found immensely fascinating were the little models of shops, people, cars, bicycles etc. which formed the setting within which the trains were plying. I presume that the models represented some form of reality which must have existed 60 years ago. The deserted roads, the old beetles, an afterthought of a graffiti on the wall, little kids playing soccer, a wedding scene, all with a moving train in the backdrop.

Through the years of writing on this portal I have witnessed reality bleed into my words, its hard edged, metallic backdrop bluntly shining behind the thin gauze of my thoughts and imaginations. I have let the silent cozy infinite expanse of the bluegreen Pacific with its silvery surface in the distance and its faint purpleorange reflections seep into the pores of my words during times of both joy and distress. And many a times I have stopped to catch my breath beneath the shades of its plangent melancholy as the mighty orb of orange rolled to its end and extinguished in its infinite moistness. I have often found myself at its shores, amidst its swirling sand patterns and have wondered whether in its jagged surface of many footprints and many swells, in its bleak reflections and its elongated shadows, there are metaphors to be found for my own experiences of life. I have often juxtaposed its limitless expanse against the neat little ribboned box of life and have found myself overcome by the comparison. Those beautiful cloud patterns through which shoot arrows of gold and those immense puddles of lights on its surface, that clockwork of the waves which weave the skirt of the ocean with white cottony frills and crawl up to the headlands only to vanish among the billions of little motes of sand. There is something immense and and infinitely intricate about it and it's only natural that it acts as a certain foil to life and I have often found myself being drawn to this contrast. The reality of my time near the Pacific, its amorphous essence, has bled into my thoughts and stained its fabric with an indelible hue. And as I raise that fabric and look at the world through it, I see metaphors and juxtapositions, comparisons and ironies emerge from the subconscious and take me by surprise. I thus stand endlessly amused.

Could of, would of and should of

I have been coming across a strange linguistic twist lately which has piqued my curiosity. I have been noticing an increasing usage of phrases like 'could of', 'would of' and 'should of' instead of 'could have', 'would have', and 'should have' respectively. I can hazard a guess as to why this change is taking place and it has to do with a destructive force in language which is geared towards economy of effort. As time passes, words in any language coalesce together, lose their stresses in various parts, and morph in different ways to strive towards more and more efficiency of expression and communication. This is a very well documented phenomenon and is a major source of linguistic change. It is, therefore, not surprising that a sequence of words like 'could have', which occurs commonly together and is often pronounced like 'could've' due to the efficiency of expression, has now morphed to the altered spelling 'could of' (see Elision).

I wondered if there was a way by which I can verify whether this relatively new phenomenon is gaining ground. I thought that an obvious first step would be to check what Google trends says about the phrase "could of". Here is the result:

Apart from the weird peak the plot above shows a general increase in the number of searches for the phrase 'could of' since 2004. The plot below shows the Trends results for the phrase 'would of':

which again shows a general increase in the number of searches of the emerging phrase. But these plots only show that the awareness for the new terms is increasing. They don't necessarily mean that the usage is similarly increasing. To find out if the actual usage of, say, 'would of' is increasing, I did a simple Google search for the phrase and restricted the results over calendar years from 2004 to present. The results showed the number of pages in which the new phrase 'would of' was mentioned. Apart from the first few results which invariably were about how 'would of' is a misuse of the phrase 'would have', the overwhelming majority of the results were actual usages. What I mean to say is that the number of pages returned by Google for a search query 'would of' is very indicative of the relative popularity of the expression. Obviously this number by itself doesn't mean anything since the total number of pages indexed by Google each year is continuously increasing. Therefore, I normalized the number of pages returned by Google containing the phrase 'would of' in a certain year by the number of pages returned by Google for a very simple search query like 'have' in the same year. This normalizes the results and gives us a pretty good description of how the popularity of the new phrases are increasing. Here are the results for the phrases "could of', 'would of', and 'should of':

Very informative isn't it? The trends are clear and if there is something to be learned from the above then it is the fact that we are witnessing a small transition in the English language and the day may not be far when the traditional forms of the phrases discussed above remain no longer in vogue. It seems ridiculous now that somebody could have spelled could have as could of. Really, they should of more brains than that!

Future of Education

When I started thinking about how education would change in the future, I was instantly faced with the classic difficulty which a specialist faces when he tries to answer a general question. If you are into science and if you've ever tried to paint, you would know, in analogue, what I am talking about. While sketching, the technical training that I have received forces me to be lost in the minutiae with the result being that I lose the bigger perspective of the scene. Similarly in life, I feel that my professional training is often a hindrance when it comes to general ideas. Being general invariably means that there would be exceptions and inconsistencies in my assertions and my small life in science has taught me not to tolerate them. But let's try something different here. Let's try to conjecture, in general terms, how education is going to change in the future, and look the other way if it doesn't turn out to be so. Let's ignore the texture of the road for its infinite expanse, for our resources are limited!

Prediction is always fraught with difficulties and is often wrong but there are some general trends which appear consistent through history. One such trend is consolidation. Beginning from small hunter gatherer communities, humanity has undergone successive consolidations in all its endeavors. In geopolitics, there have been eras of skirmishes which were eventually followed by larger entities. These larger entities which initially suffered from an unstable equilibrium finally gave way to more peaceful societies within them. The new skirmishes were larger and took place between these larger entities, eventually resulting in even larger ones. Perhaps the single most important reason in this cycle of skirmish and consolidation was technology. With new means of transport and warfare, societies could seek to influence larger geophysical areas. Under the umbrella of technology, therefore, we have the crude chisel of social evolution.

Now how does this model apply to education? There must have been a time when education was much more personal than it is now. It also must have been very different from what it is now. Its form must have consisted of two distinct parts: training and philosophy. Training would have consisted mainly of 'tricks of the trade' passed from one generation to another, like knowledge about farming or selling merchandise. Philosophy would have consisted of all thought geared towards figuring out the world around with little or no immediate tangible benefit. The means of imparting education would have consisted of small intimate groups and oral communication.  This process suffers from some obvious handicaps. First, it makes education a rare commodity and it would surely have helped in creating rigid boundaries in any society. The caste system in India is a relic but the same thing must have existed in Western societies with the monopoly of the Church over knowledge and education in the dark to the middle ages (you only have to notice that most of the great poets and scientists before the 18th century were either wealthy or from a noble lineage to realize that education was for elites). The second problem with such a system is that any given teacher may not have been the most knowledgeable on his subject.

This would have changed with the invention of the Gutenberg press which allowed the wide dissemination of printed materials. Teaching would have become more codified so that it could be imparted to more people. Furthermore, books written by specialists would have solved the second problem as well. Now there could be regional centers which could provide reasonably good education based upon the more concrete nature of it: the advent of the modern university. Now at this point it is worth remembering a major pitfall of these changes. While on one hand they led to many more people getting educated, on the other they also led to a dilution of the very education that was being imparted, a dilution that continues to this day. Since in society there always exists a need to distinguish individuals based upon various factors, the all pervasive nature of the current educational climate makes it essential that there must exist a different kind of hierarchy: the hierarchy of degrees and of schools. The rigid compartmentalization which resulted from the rare nature of early education has morphed into a compartmentalization that is now fueled merely by a different kind of rarity.

Anyway what does all of this tell about the future of education? In simple words! I think that we are on the cusp of another monumental change which is being driven by the technological breakthrough of the Internet. The future is getting clearer and it looks similar to the past, at least metaphorically. We are already witnessing the seeds of change in the form of online learning initiatives like edX and Coursera. I imagine that there would be many more such initiatives and at least for some more time the field of online learning would appear analogous in spirit to the Wild Wild West with many competing players. But it would eventually simmer down into a more consolidated platform where very competent professors from around the world would contribute their lectures and videos and course materials to an organization which would probably span many different universities. The nature of the Internet would make it available to millions of people across national boundaries. We would have both another consolidation and also more widely available access to education of much higher quality. It appears inevitable that the competencies gained through online learning would one day command the same legitimacy that the traditional educational degrees currently have. This would lead to a financial incentive which would lead to a very fundamental change in the concept of a university. Since no single university would be able to offer what a conglomerate of universities would be able to offer, we would perhaps witness a dissolution of the current heavyweights.  We would most certainly see a devaluation of the reputation and clout of universities which cling to the old order. In fact we may start witnessing that within the next decade. High quality education would be accessible to many more people around the world and it would be much more uniform and standardized than it is now.

This would  lead to another cycle of dilution and if, just if, we try to look far enough into the future, we can perhaps conjecture about the nature of it. I feel that degrees and specializations would eventually lose their conventional meaning in the world of online learning. It made sense to compartmentalize education based on our current scheme in the times of industrial revolution. We live in times of a digital revolution where it is not required for people to have core competencies even to do highly specialized  tasks. For example it is beneficial but not required for a mechanical engineer to know the Navier-Stokes equation in order to find out how a fuselage responds to air turbulence (in fact it doesn't help much!). And that benefit is already running thin. I think that the educational future would be one which would be respectful and cognizant of its digital tools. But we shall leave the rest of the conjecturing to some other time.

Digressions - 1

Several years ago I came across a TED talk by a famous physicist called David Deutsch and I thought that it was the best talk that I had ever seen. He talked about our place in the universe in the context of how humans figure out new knowledge about our surroundings and then he went on to connect his talk with the current problems facing the human race and what's the right way to go about figuring out the solutions. I went ahead and bought his book called "the fabric of reality" and was immensely impressed by the ideas presented in the book.

In his book, he tried to put forth the case that four of our current theories, put together, may already suffice well enough to serve as the theory of everything. A critique of his claim is beyond both the scope of this post and perhaps even my intelligence but one of the theories that he talks about is Karl Popper's theory of the growth of human knowledge. I was very intrigued by Popper's idea that the process of new scientific advance is deductive as opposed to inductive. This means that revolutionary new scientific understanding almost never comes from observing nature but simply by a process which, for all practical purposes, is the same as guessing. Obviously verification and fine tuning are still within the domain of observing and learning but the seed of new science is basically just a hunch. I came across this concept yet again in a YouTube video of a physics lecture that Feynman gave in Cornell (highly recommended again). But it was only recently that I got the chance to read Popper's original paper which first presented his theory. He presented it in the context of the philosophy of the pre-Socratic Greek philosophers.

The great Carl Sagan begins his TV series Cosmos, which to me is the greatest TV series ever made, with an introduction to the philosophies of such names as Thales, Anaximander, Democritus, Heraclitus and more. These people lived around 500 BC in the geographical region which now constitutes parts of southern Italy, Greece, and western Turkey and they wondered about the deeper questions of life. Specifically, they tried to explain the inner workings of the world around them. By modern standards, their explanations would appear ad-hoc and childish but it is easy to see that their ideas must have been groundbreaking in their time. They presented a distinct break from the anthropocentric Greek legends and they tried to give a mechanistic explanation of the world. And by criticizing each other and building upon each other's theories, they laid the foundation of the Western scientific tradition. It is also fascinating to see how 'far out' their explanations are and it is evident that their understanding is more guesswork than studied induction.

It takes a special society to tolerate such imagination and creativity, especially when the creative energies are focused towards the deepest questions that there are. It was not before long that this frail tolerance was lost to dogmatic views of the world with the advent of Plato and Aristotle. While western science finally recovered from the dark ages with Galileo, and the western thought with the beginning of Rennaisance, it is interesting to note that this success was never repeated anywhere else. I'm sure that the ancient Indian philosophers asked the same questions that the Greeks did and I'm sure that their answers were equally insightful and beautiful. I'm sure that there existed a time when the philosophers were merely feeling their way in the dark and their theories and thoughts were open to severe criticisms. But today the Bhagwad Gita, for example, is used to ensure that witnesses do not lie in court, thereby imparting to it a rigidity which would have been anathema to the philosophers who contributed to the great work. Other religions have similar stories but I find it odd that the Hindu equivalent of Bible and Koran is the Gita.

So what's the point of this post? Digressions!

Galaxy Note 2

This post was handwritten (not typed) on a Galaxy Note 2 screen.

-----------------

The first laptop that I bought after coming to the US was an apple iBook. It was made out of white plastic, had 512MB of RAM, 40GB of hard-disk space, and a 12 inch screen. In a world infested with gargantuan and sad looking black laptops, it screamed coolness as I took it everywhere from the library to the beach and to the coffee shops. It wasn't very useful though and it became apparent very quickly. Its lack of serious computational capability meant that very soon it became outdated in terms of the software that it could run. This, in addition to the already limited ability that the OSX suffered from when it came to useful scientific software. While Apple has since produced great and fast hardware, I cannot imagine its OS being very useful in a scientific setting. In fact, as has been said time and again, Apple produces beautiful products with a very high degree of craftsmanship, but which are only mildly useful when it comes to productivity.

This meant that the next laptop that I got was a screamer of a Windows machine. 8GB RAM, quad core i7 processor, a TB of storage. It didn't look nearly as good as an Apple machine looks but it runs pretty much anything that you can throw at it. And in addition to its computational brawn, since it runs Windows it is also capable of running the simulation softwares that I end up using sometimes.

The reason I am mentioning all this is that a similar transformation has occurred in the area of smartphones. I began with the beautiful iPhone but soon realized that it was too constricting as an OS. This prompted a switch to Google's Android operating system in the form of the awesome Nexus S. The phone had better and more powerful specs than my first laptop and the operating system seemed to provide additional capabilities which the iPhone never did. But such is the pace of technology that a phone with a 1GHz processor and 1GB of RAM soon started stuttering when faced with prospects of all that was expected of it. This made me finally decide to get the last word in mobile technology, something that I do not think would get outdated in the next few years. And what a phone it is!

Samsung Galaxy Note 2 is a behemoth of a phone with a positively monstrous 5.5 inch screen, a speedy quad-core processor, 2GB RAM, a battery which lasts 2 days on a charge, and the most important addition of them all - a stylus coupled with software that Samsung must be proud of. For instance, I am so incredibly impressed by the handwriting recognition capabilities of the phone that I decided to 'write' this whole post on the phone's screen, and I did it with minimum corrections. The recognition is so good on this phone that it is now a legitimate form of input and one which may even be faster than typing on the keyboard. Google's voice input is pretty amazing but it is still much less consistent than this brilliant handwriting recognition system. I must confess that I am a technophile and I am simply amazed by the march of technology. Obviously there are both pros and cons to it but it has provided us with options which never existed before. Seeing what the mobile computation devices of today can accomplish is both stunning and a little disconcerting. Samsung Galaxy Note 2 is just such a gadget which makes you wonder if the future has arrived prematurely!

Portland to San Francisco

I got the chance to drive from Portland to Oregon and what a great road-trip it was. The stunning greenery of Oregon coast is matched well with the majestic wilderness of North Californian coast. Click for full panorama:

Elements of a good cafe

At this present moment I am sitting in a quaint little coffee shop called Grendel’s café at the intersection of NE 8th Ave. and East Burnside in Portland Oregon. The weather is brisk out with the sky gray and moist in patches but the Sun managing to shine through the patchwork, reflecting off of the black wet asphalt of the street ahead. It’s 9 in the morning and bleary eyed men with thick stubbles and grayblack hoodies walk through the pale yellow wooden door of this café to have their cup of the house blend or the French press. Portland seems to coffee shops everywhere. While walking through the streets for about a mile yesterday I counted at least 15. This speaks well of the city to me since one of the prime indicators of how interesting a region is is how seriously it takes its coffee shops. In fact I wouldn’t be surprised if there exists a correlation between the intellectual output of a region and the existence of places where people from different walks of life can get together, relax over a cup of beverage, and talk about different things. Bars do not qualify because there is nothing relaxed about them and often they are too loud to have any conversations more interesting than the cringeworthy mating ritual. Despite what they are made out to be I feel that bars in the modern society are engines of isolation whereas places like coffee shops bring people together. Moreover, a communal place is very much defined by the kind of people who visit it and bars, by their very nature, attract a certain demographic which tends to be more shallow and superficial than interesting. It’s a generalization which probably fails every now and then but it’s definitely more true than it is false.

Good coffee shops, therefore, must attract the right sort of crowd as well. This means that it’s always hard to find good coffee shops in financial centers like downtowns. I apologize if I appear to mean that people working in such fields as finance and marketing are not interesting, but it’s the truth isn’t it? Posh looking coffee shops with sharp dark interiors and high glass windows looking on to 5th avenues and Broadways which charge 5 dollars for their cappuccinos to jetsetting managers in black suits and shiny leather shoes must not be worth any reasonable man’s time. Similarly a café trying too hard to be alternative and on the edge just ends up inviting the wrong kind of clientele - the kind which is always on the lookout for the new, the hip, and the happening. A good café is, therefore, almost always to be found in a semi-urban kind of setting where it can generate a consistent following among the locals. Most people who visit it see it as a part of their daily lives. They know the baristas by name and have consistent orders. Most don’t see it as just a place to get coffee but as a place to sit and perhaps read a book or have a little chat with people whom they have come to know there. A good café is an extension of home and work for many of its patrons and it achieves this by providing a warm and cozy environment, a safe temporary little haven from the rush and bustle of the world outside. The good-natured charm of a nice café is infectious and just like most simple things in life it is often a matter of the stars lining up right for it. What it is not exclusively about is the quality of its coffee. That is almost secondary to what goes into making a great café! So here are the ones that I like in San Diego (in no particular order):

Lazy Hummingbird in Ocean Beach, Pannikin in La Jolla, LeStats in Normal Heights and University Heights, Mystic Mocha, Art of Espresso in UCSD, Peet’s in La Jolla and Hillcrest, Bird Rock coffee roasters, and above all, the most awesome Bassam café near my place.

The curious philosophy of Wilde

When I consider Oscar Wilde's writings I am forced to admit the existence of very deep seated contradictions within myself, which is weird because by his own admission he was an aesthete - a person mainly concerned with the superficialities of life. He extolled youth above experience and flamboyance above seriousness. He placed life as being secondary to art and traditional morality as mainly the preoccupation of the fogey whose best years were behind him/her. His prose is resplendent with clever paradoxes and his philosophy, at least on the surface, is the philosophy of the jaded super-intellectual who, despite being bored with the world around him, doesn't want it to change lest it might take away the pleasure that he derives by sneering at its incompetence. And this curious dichotomy of an extremely intelligent person both repulsed and morbidly dependent on his environment is not clearer anywhere than it is in his great novel 'The Picture of Dorian Gray.'

Dorian Gray is a young man who has it all. Wealth, social position, beauty and most importantly youth. What he doesn't have is much intelligence. In fact he has just the wrong amount of intelligence. Just enough to be swept away by the deviously clever logic of Lord Henry. Henry is an extreme cynic and is the mouthpiece of Wilde's philosophy in the novel. He likes Dorian for what he represents - the easy success of flamboyance and beauty and youth. He speaks eloquently and leads Dorian astray and convinces him that the only things worth having in this world are those which he already has. Dorian is eventually seduced by Henry's arguments and really believes in the idea that a life based only on pleasure and self-interest is a life worth having. Given his material success and his beauty Dorian can afford such a life too. In the middle of the novel Dorian even figures out how he can sustain his youth for eternity. The novel thus centers around a person who can have all the pleasures that he wants and for as long as he wants - a perfect Wilde ideal - and then asks the question whether all this really makes him happy.

And this brings me to my final point. I think the novel Dorian Gray is special in the Wilde canon because it is the only one which gives both sides of the story. It presents most of Wilde's philosophy through Henry and it also presents its ramifications through Dorian. Therefore, the gravitational center of the story is neither Dorian nor Henry but Wilde himself. This is the clearest that Wilde ever spoke of what he thought of his own curious take on life. Henry is Wilde and Dorian is what Wilde always hoped for but could never be. In fact if you really consider Wilde's writings in their totality you would find a curious undercurrent. His main characters are sharp gentlemen with biting wits and they all display little patience with the banalities of society but they are all fairly conventional people with conventional marriages. Dorian Gray is his only character who lives what Wilde philosophizes and he is the only central character to not have the intelligence to come up with that philosophy himself. Henry who comes up with Wilde's philosophy is intelligent enough not to follow it and thus has a very safe and conventional life.

So we finally come to this contradiction which I mentioned earlier. To some his (or Henry's) take on life is shallow but it is not to me. I think his seemingly ridiculous and shallow generalizations always have a deeper hidden truth, a concise acerbic little social comment by one who is much more intelligent than most. In fact, he is sufficiently intelligent to also understand that acting upon his philosophies would end up in disaster. This is a tacit approval of the very society that he mocks and therein lies the apparent contradiction. Now one may feel betrayed by Wilde's implicit volte-face but this backdoor compromise is the mark of someone who thought deeply. After all, both conformists and rebels in this world are a dime a dozen!

Mechanical watches

It's an understatement to say that I have become fascinated with watches, especially mechanical watches. There is something about the precision engineering of a well made piece, its pulsating mechanical harmony, its artistic idea that satisfies the engineer, the scientist and the artist (to whatever degree it exists) in me. Because a mechanical watch really is a work of art since as an object of utility its pretty useless when compared to a simple quartz watch. Following is the story of the mechanical watch in a nutshell.

As I mentioned in my last post on the topic, all clocks and watches have a timekeeping source. In the grandfather clock it is the pendulum and in the mechanical wristwatch it's a balance spring. The Europeans (especially the Swiss and the English) had a huge headstart in designing and making precision mechanical wristwatches with the 2 towering figures of the field being Abraham Louis Breguet and John Arnold. Between the two of them they pretty much invented every important nuance of watchmaking. Everything was hunky dory for the Europeans before the Japanese entered into watchmaking in the 1960s. It was discovered that rather than using a balance spring as a timekeeping source, a quartz crystal can be used instead. Watches made using a quartz crystal would not only be much more simple to make but they would also be extremely cheap and much more accurate than the traditional mechanical watches. Swiss initially decided not to go the way of the quartz and got almost wiped out by the Japanese (Seiko, Citizen) and the Americans (Texas Instruments, National Semiconductors). The Swiss finally caught up in the quartz race through the formation of the Swatchgroup but they also repositioned the traditional mechanical watch as less of a utilitarian timekeeper and more of a thing of beauty.

Master watch-makers would toil away in the Vallée de Joux with their tweezers and their lenses, with their lathes and minuscule files and produce after months and sometimes years of hard-work a single mechanical watch, a stunning piece of craftsmanship and a true labor of love. These watches would have hundreds of microscopic moving parts, precision machined gears, elaborately patterned surfaces (Guilloché), jewel bearings to minimize friction, and automatic self-winding mechanisms. Since it is much more difficult to add additional functionality to a mechanical watch than it is to a digital watch, adding complications became a way to exhibit the artistry of an accomplished watchmaker. And with all those complications and all those gears ticking away in harmony, sometimes the watchmakers make the back and front transparent (Skeleton watch) and the beautiful clockwork of a well made mechanical watch takes its rightful position as a work of art. And you can be sure that horology of mechanical watches is more art than engineering by its vocabulary. It includes fine elegant French sounding names for different complications (Tourbillon, Sonnerie, Rattapante) and the famous watchmakers do their own versions of them. It's like Horowitz performing a Chopin piece or Van Gogh's doing a 'still life'.

And the result of all this is that even though these mechanical watches are not nearly as accurate as a quartz watch that you can get for 20 dollars, they can easily command prices in the high six figure range! And what do you get for all that? The following, for example:
