Siddhartha


I read this book a couple of weeks back, but couldn't write anything about it. The book had been written by Herman Hesse who's a well respected German author, who once even won the Nobel prize for literature.

When I saw this book on display in the library I thought it to be a peice of fiction based on the life of Price Siddhartha before he left his palace in search of salvation, a work similar to that of Martin Wickramasinghe's "Bhavatharanaya". But it was not to be so. When I started reading it only did I discover that the Siddhartha referred to in the book is not the same prince Siddhartha who atained enlightenment and came to be known as Lord Buddha, but a different person, a Brahmin's son who lived in India during the time of Lord Buddha.

It's a fairly short story, and the story goes as this Siddhartha along with his friend goes in search of the meaning of existence. And just like the prince Siddhartha we know he goes onto learn different beliefs and practice rituals etc. under different teachers but realizes that they are not the liberation that he's looking for. After some time they both pay a visit to Lord Buddha, who they have been hearing so much about.

However, the story takes an unexpected turn here, and from this point onwards I think Hesse had got it all wrong.

Lord Buddha only appears in this book for a very short time, and at this point Siddhartha's friend decides to stay and become a Buddhist monk. However, the main character of the story Siddhartha decides to move on in search of self-realization. His argument is that there's no point in learning from someone else, but you have to realize the path by yourself alone. This point is not directly in contradiction with Buddhism, which says that you shouldn't believe in something just because someone says so or it's written in some book etc.. but analyse it and after due examination if it's intended to be good towards all others you may take it in. (From Kalama Sutta: but not the exact words, sorry about that) anyway, my point is that this doesn't necessarily mean that you should disregard what all others say.

Anyway, this Siddhartha goes on with life, searching for whatever he's searching for, and gets himself entangled with a courtesian, I think this woman named "kamala" is taken from the character of "Ambapali" in Buddhist texts. For later in the story this Kamala donates her mango grove to the Buddhist monks.

So, Siddhartha gets himself in a lot of different situations and finally one day suddenly ends up realizing that this life is meaningless! And goes in search of self-realization again.

The story I thought was pretty weird. The worst thing about it was that Hesse had to name this character as "Siddhartha". I kept wondering about that all throughout the story. Didn't make any sense at all. Perhaps he expected this character to be a close image of Lord Buddha himself. The introduction to the book was given by a scholar who had been studying Buddhism, and he had mentioned that "Hesse's understanding of Buddhism was not very accurate".

In my opinion, this is a book which is not worth reading, it only leaves you confused. Unless you are one of those people who just love to criticise others work!

Weekend...

Friday night we watched the Sri Lanka Vs India match over the internet. Had a couple of hours sleep before getting up at midnight to watch the match. yeah.. it was not a nice feeling, so only watched the SL innings, then went to sleep at 4am and got up again at around 7, the match was over by that time. So watched the highlights. We are through to the Super 8. I saw a photo on today's online Daily News, a soldier guarding Rahul Dravid's house...hmm.....

On Saturday we went to Marion which is a large shopping centre a little more half an hour's drive from the city. Next went to see a kite festival in one of the beaches. Wasn't as grand as it was advertised I guess.

Sunday at home, the usual household work laundry, cooking, ironing, cleaning etc...
We bought a set of badminton rackets so spent a couple of hours Sunday evening brushing up on our badminton skills, sent the shuttle-cock flying over to a neighbours place a couple of times. However, the weather is getting a bit too cold for outdoor sports now.

Got a new book from the library, Sir Richard Branson's autobiography (the owner of the multi-national Virgin group of companies) titled "Losing my virginity" yeah, it's a weird name, but the guy is weird too. He's one of those people you would have trouble distinguishing between 'genius' and 'mad-man'. I was thinking of just skimming through the book without spending hours, but once I started on it, it just looks too interesting to do that.

We won!

Got up a bit early to follow the SL Vs Bangladesh match on the net. No game, we won by 198 runs on a Duckworth-Lewis decision. It's nice to see all our key batsmen putting up good scores for a change (without the usual one-man show).

Hope they would keep up the good work!

Mysterious vibrations

For the past few days I've been trying to figure out whether my lab setup is stable enough to carry out experiments. I've got a vibration isolated 800kg steel table, which measures about 3m long and 1.5m wide, sitting on a concrete block which is something like 7m long. And this whole thing is pumped up in pressurised air just to isolate it from the ground vibrations.

So effectively my experiment which will be sitting on the table and the concrete block will be completely isolated from any ground vibrations. But when I set up a scheme - an interferometer to check this, the table was very good but the concrete showed a small vibration. It's in the scale of micrometers and nanometers, but in optics that's a big issue. I turned off all AC's, exhaust fans and asked my colleagues to keep their voices down, but still I couldn't get rid of the confounded vibration.

It got my supervisor and the other students also thinking.. but finally we managed to find a work-around to it. The vibrations are still there, but I'm going to set up my experiment so that the vibrations will be compensated.

So that done, I'm sitting here blogging, waiting for my big mirror (1m diameter) to be lifted up and mounted for me. That should be done by today afternoon - hopefully!

No Comments?

I feel like I'm doing all the talking!

Lasers in a nutshell


When someone mentions "Laser" we are instantly reminded of a bright light beam whether it's from a James Bond movie or from a stage display. But what exactly is a Laser?

In plain English, it's only a light source. Just like an ordinary light bulb or sunlight, a laser emits light. So what's so special about a laser? Well, there are a couple of differences, the major one being the high degree of coherence (I'm not going to explain that now since it's going to be very technical) another is the high intensities they can produce.

In some instances Laser intensities can be so high that just by looking at an object illuminated by a laser can burn your eyes for good! So lasers are categorised according to the level of damage that they can cause. Therefore lasers categorised as class 3 and above require wearing goggles and protective clothing.

A description of the importance of lasers is beyond my scope, they range from medical applications such as cancer cell burning and teeth whitening to metal cutting, engraving, and precision measurements of incredibly small distances, (I'm talking in the nanometer range).

I'll write about my research later on, for the moment I'm using a He-Ne laser which is categorised as 3B, that means I have to wear goggles, which can be quite a pain, for it cuts out most of the light and I keep knocking on things in the lab like a blind bat!

What did I tell ya?

In the chain of events following Pakistan's cricket world cup controversy, Captain Inzamam Ul-Haq is retiring from One-days.

....................

Shockers!

Some world cup this is turning out to be!

It all started when Bangladesh beat the daylights out of India over a 5-wicket victory. Even though it was unexpected it was still not unbelievable. Next day some of my colleagues were debating whether non-test playing countries like Netherlands, Scotland, Ireland, Bermuda etc should be given the chance to play in the world cup. After all it's THE world cup, it's a big thing to even participate in it, so teams should fight to get in!

And Voila!! Ireland defeated Pakistan! and threw them out of the tournament! That was a big stunner!!

Next even before that news was digested, came the news that Bob Woolmer, the Pakistani coach had collapsed and died! within 24 hours of Pakistan's defeat. hmm.......I wonder what the next shocker is going to be.

Water

Today we watched the film "Water" directed by Deepa Mehta. I'm not going to go into details about it simply because I'm just too tired after playing cricket with Vishuddhi. Anyhow, the film is about child marriages in India, which is supposedly practiced even today. The film was mostly shot in Sri Lanka and casts a few of Sri Lankan actors like Iranganie Serasinghe and Buddhi Wickrama, and of course the main character Sarala.

Cricket World Cup 2007

The Cricket world cup is here! Not here exactly, it's on the other side of the planet, in the West Indies. And I'm REALLY, REALLY annoyed that the tv stations here are not broadcasting it!!!!!!!!!!! It's the world cup for god's sakes!!!#^%@!&$!!!!

I suspect they are hoping to telecast some of the 'good' matches that Australia will be playing. But that's not fair!!!

I guess we'll have to rely on cricinfo.com for the scores.

I hope Sri Lanka wins! Failing which, anyone but Australia.

For your own safety

Next Tuesday supposedly there are some folks coming from some OHS (Occupational Health and Safety) thing to evaluate the safe work practices in the Physics building. Much to the annoyance of practically everybody!! Well, we are doing quite well without them, aren't we?

The lab wardens and technicians are annoyed since they are required to take care of all safety related actions and be prepared to deal with these folks, because if something goes wrong they will be partly responsible. The supervisors are annoyed since this 'monkey business' is taking up lot of useful time (research time). And students are annoyed because we are supposed to read up and be prepared to answer all sorts of possible questions they could ask, instead of doing our work! And of course this means that the lab warden would not have time to put up my optical table till after next Tuesday!!!@!?@*#&^!!?!

I don't know why we have to go through these stuff. We very well know how to use a Laser, to wear eye safety and not to poke our fingers into a high-voltage outlet! And above all, only authorised persons are allowed in the laser labs, so there is no risk of some curious passer-by getting into one of them. And of course there are those fire drills that goes off every now and then and we have to abandon all our work and go out of the building - just for fun!!! next there are those forms that we are required to fill out every now and then.

All these paraphernalia is just wasting time. I know it's better to be prepared than be sorry, but seriously there should be a limit!!

One of my colleagues actually believe that he will come down with some mysterious illness on Tuesday. And another a pure Australian, hoping to pretend that he's from France and can't speak any English! Well, he wouldn't get further than "Parlez-vous Francaise?" on that, and specially not if one of the evaluators happens to be fluent in French!...hmm......that would be fun!

Anticipating work

Gloomy day....no sunshine at all...and very cold...... seems like the winter is on its way...brrrrr!!!!!!

After a lot of remindings and pressuring, the setting up of my lab has been accelerated. So the whole day the lab warden was busy with that work. a-ha!

And I've been trying to understand "surface enhanced Raman scattering", dozing off......reading wikipedia, raman scattering, answering mails, raman scattering ..... I wish they would finish my lab soon!!

The Whispering Wall........shhh!

Last Saturday we went further north-east of Adelaide to see Gawler, which has been one of the earliest white settlements in the area. Well, it's not that old, just around a century and a half.

The interesting thing around the area was the Barossa reservoir, better known as "The whispering wall". On the outside it looks like just another dam with an arched shape, retaining water on one side and trees and shrubs on the other.

But the funny thing about it is, that when you stand close to the dam wall at one end of the reservoir, you can hear a person talking at the other end (that's about 150 meters afar), as if he's standing right next to you! Spooky!!

The secret is in the shape of the dam. The tall thin concrete dam curved against the pressure of the water had been radical at the time of construction over a 100 years ago and the parabola effect causes sound-waves to bounce so that people speaking at one end of the dam can be heard as if the person is standing beside you ! The wall is one sector of a perfect circle, and the sound-waves bounce in a series of straight jumps along it to the other end. Cool!!
