Advertisement for a new blog

With a newer station in life, and increased responsibilities, I have decided to modify and curtail my blogging habits. This is the address of my new blog:  http://anindianinisrael.wordpress.com/
The title and the intro line are pretty self-explanatory, and from now on the bulk of my blogging will be  about my work and life in a new country. I promise to spare any readers that I might have, the moping and whining that I often poured into my blogs - a blog cannot and should not have to, I have decided, reflect my raw, untamed thoughts or emotions of the moment. I might occasionally get bored of reality and journalistic impressions though, and resort to fiction, which will from time to time continue to be published in this  old blog. I wish you all, the people who have read, followed or commented on my blog over the last three years, the very best in your respective lives and endeavors, and post my last post here for a while hoping for the outside chance that you might read it one day and take a look at my new blog.

Cautiously optimistic misanthropy


Reason is too much to hope for: this world is after all populated by filthy, hairy, primates. These nauseating creatures like to label things and themselves. They like to classify, compare, give names to things, and distinguish them from others. Their categories always come in pairs of mutual opposites.  One such dichotomy is between the liberal and the conservative.  The former likes to leave everything to the individual's judgement, and assumes that as long as it doesn't directly harm someone, anything goes, emphasis of course on the "directly".  These misguided fools live in abject denial and find themselves trapped in an amoral universe of confusion and conflict - what the Vedic philosophers would have called "bhrama".  The other type believes that things are for a reason, though it is not for us to question why, not because we are filthy dumb primates but because we are little children possibly designed by some abstract benevolent force, who has also designed the rules by the way. So there should be no reason to change anything, rules, customs, and traditions - since they are preordained for our own good, and because change is uncomfortable.  These fools would stick with the basest of customs as part of 'tradition' and curb individual rebellions with punitive action.  The illusion that the system was designed perfectly and following some pre-ordained rules will solve all problems: "Bhrama" here too.

What then are we to make of this civilization of filthy primates, whose members are torn between one of two, equally unappetizing extremes?  In fact as the existentialists would say, there is not much sense to look forward to  in the first place.  Yet the primate tendency to order, organize and structure things in the mind, which later led to agriculture and city life, must have its own merits, one of which being that this is one of the few redeeming things about the primates. That this desire to instill order, to plan ahead, to infuse structure, is often frustrated by ambient circumstances, makes it quite a pathetic desire. Evolution and mate selection clearly do not favor the desire for "order", while material success in a modern economy relies almost squarely on the later.  Certain traits  possibly unfavorable to evolution, such as the tendency to over-analyze and look for order amidst an otherwise chaotic turn of affairs,  are however assets in a modern society.  This "social evolution", so to speak, gives us some hope for the future that the crude, instinctive, beast would be replaced by a more sapient, rational human.  
This will perhaps lead to a better understanding of things, will rescue them from the morass of "bhrama", and things might seem more meaningful then.

The power of solar energy

The world consumed energy at the average rate of 10^13 W in 2011 (the figure is probably increasing at a global average of 10% a year).  This like keeping 100 billion 100-Watt bulbs switched on at the same time.

I am not sure how much of this energy consumption is in the form of electricity.  We do consume a lot of energy in other forms, such as food, or gas, and I am assuming this wikipedia estimate takes everything into account.

A quick calculation shows that the earth receives about 10^17 Watt of energy from the sun on an average. Of course how much reaches the ground depends on local factors, like if there's a lot of cloud cover there would be a lot less solar radiation reaching the earth. But the amount of energy reaching the outer layers of the earth's atmosphere is fairly constant, because the Sun has been burning brightly at about the same level of brightness for many million years now, and is expected to do so for quite a while now. This so-called "solar constant" is the power reaching a unit surface area of the earth's atmosphere, and is estimated to be about 1400 W/m^2.  Multiply that by the earth's surface area which is about 10^14 m^2, and we get the above quoted figure of 10^17 W.

Of course a large percent is absorbed by the atmosphere, but if we built solar panels to cover 1% of the earth's surface area (that's a lot but let's suppose we can do it by covering every house rooftop, several deserts, and even have some floating on the ocean whose energy can be channeled offshore using underwater cables.) , and extracted energy from it with a humble efficiency of 1%, we would still have 10^13 W of power production.  This is equal to the planet's total energy consumption! We could reduce that by a factor of half given that the solar panels are not working at night time, but we still have a lot more energy than is consumed as electricity.

There is no reason then not to invest in solar energy technology. The Sun is here to stay in the foreseeable future of the human race.  The efficiency of light-to-electricity conversion can only get better. So will the other technological aspects such as energy storage and transport. Even as we speak, many research groups around the world are developing better photodiodes (that efficiently convert light to electricity) and better batteries (to store this energy).  All things taken together, the costs will come down, and the rates of production will increase.  This is what countries in the European Union, such as Denmark or Germany have been doing....investing in clean, renewable and non-hazardous sources of energy.  The US, the usual suspect, lags behind on this front. I live in the "Sunshine state" of Florida and have rarely seen houses fitted with solar panels, much less people talk about it.  The vibes I get from the media are also negative. Obama was heavily criticized for investing in a solar company that failed (the weird laws of market economics always find a way to stand in the common-sensical laws of physics).

These estimates are all some amateurish off-the-top-of-head quick and dirty estimates, the product of one morning's "research" on wiki. So i might have missed a lot of important points or nuances, but you can't argue with these numbers.  I wish I lived and worked in a place where people talked more about these things, so that some of it rubbed off on me. One of the strengths of people with an education in the physical and mathematical sciences is that we can make these estimates and play with numbers to get a good big picture in most things - be it energy, biology or economics. I am itching to flex that muscle on such matters of social import, rather than just some esoteric stuff (which is what I currently do and somewhat enjoy). Maybe I will go to such a place next.

Noir Comics

"Sometimes it's luck that saves them.....sometimes it's fate"...said in a deliberate,  deep, hoarse, masculine, American voice while you see a dark alleyway, somber faces, blonde damsels in distress with twisted sides, and sink into the general mood of pessimistic, masochistic, machismo... the mind craves some noir comics. Right about now. A visit to the bookstore might be in order soon.

Ode to Madame Cama


Madame Bhikaji Rustomji Cama
was no mere queen of drama
In 1907 she did unfurl a flag
which the British rulers did nag.
She talked and moved with a prance
and went to live in Paris, France
before old age dulled her vehemence
'n she was thrown on a Tower of Silence.
