Last Crop Of 2010

Now that the temperature is dropping below freezing, I decided to remove all the tomatoes and jalapenos (and other peppers) from the plants. Made a huge batch of Insane Hot Tomatillo Salsa.


Take this quick quiz. How many tomatoes and peppers are there ? :-)

The Tipping Point



Book Review : The Tipping Point
Author : Malcolm Gladwell
My Rating : 3 out of 5

The complete title of the book is "The Tipping Point: How Little Things Can Make a Big Difference".

When I read "Outliers" by Malcolm Gladwell, I had mixed reactions. I thought the author wrote a very nice to read book but was portraying some great insight which we already know via common sense. Still I was interested in trying his earlier books. After reading "Tipping Point", I hate to say this, but I don't think I will read his other books.

The books have the same format - interesting anecdotes mixed with author's assertions. In "Tipping Point", Gladwell is examining how a certain product suddenly becomes popular, how something becomes a fad - in short how a "meme goes viral".

This is a very interesting investigation. Gladwell classifies the concepts into various labels - Mavens, Connectors, Salesperson, Power of the context, Law of the few, Stickiness factor etc. Gladwell explains his labels well. There are enough interesting people and stories to keep the reader engaged. Gladwell supports his assertions using diverse stories that range from children's shows to religious groups to crime rates in New York.

All this is fine, and the book is easy to read. It did become a big long and repetitive for me by the end. But that could be just me. The real problem is - the whole premise feels unscientific. This is not real new research in any field of study, but it's presented as such. Like "Outliers", Gladwell is just quoting other researchers in this book. He does a good job of connecting their inferences and there is no plagiarism, but there is very little original contribution. And much less in the way of any new insight. Most of it is just common sense deductions arranged in a pseudo-scientific package.

In spite of giving it the 3 star rating, I may be coming off as a bit too harsh and negative. It's not a bad book, it's just that it doesn't deliver what it promises. The superficiality is frustrating. I know that books should be fun read in order to appeal to as much audience as possible, but serious research and original insight can be fun as numerous books have done - like "Freakonomics" or "Guns, Germs and Steel". This book may help you pass an idle evening or have some nice discussions around lunch table. But that's about it. Expect more, and you will be disappointed.

They Really Said It ! [9]

Love him, or hate him, you have to hand it to Peter Schiff on how correct he was and how well he handled all the slander and ridicule he received.

This is a compilation from 2006-2007. Some choicest statement from Peter Schiff's opponent Art Laffer
- US Economy has never been in better shape
- The monetary policy is "spectacular"

The next one have an "expert" proclaiming a return to "only" 10% annual appreciation as that's how the "normal" market works ! Another one shouts "what artificial lending standards you are talking about" and starts laughing at Peter Schiff.

Then we have the famous Ben Stein claiming that the "credit crunch is way overblown" and "subprime problem is a TINY problem". He further advises us as "buying opportunity of the lifetime" when Dow was over 13K. It dropped nearly 50% from there and even today is 15% below his lifetime buying opportunity. Peter Schiff retorts - "The party is over for US". Then everybody proclaims, "Worst is over" and only Pter Schiff says, "the worst is yet to come". Oh, and it gets even hilarious - everyone loves financial stocks - and only Peter Schiff says, "they are toxic".



The following video is just too brutally hilarious. What else can you expect when a Realtor goes against Peter Schiff ?

THE Simplest Recipe for Artisan Bread

Who doesn't like eating fresh, hot from oven bread ? But most people find the entire process of baking bread very intimidating. First you have to use the right ingredients, get the proportions just exact, then knead the dough to a perfect consistency, let it rise and proof for just the right duration and then bake it at exactly for so long at an exact temperature. The amount of parameters that you have to think about make buying a digital camera seem like a child's play.

What's so special about this recipe ?
I have a very simple recipe, based on ideas from a few books and it will give you a very good artisan bread. It won't win you any prizes in bread baking competitions, but what makes it great is

1. It's very forgiving, you don't need to be super-perfect in order to get it right.
2. It uses the minimum possible ingredients, and can be very healthy if you use 100% whole wheat flour.
3. It provides ample scope for your creativity to do variations on the same theme to get very different breads. More on that later.
4. It's very flexible and can be adjusted to meet your schedule. I will cover that later, for now, let's keep things simple.
5. And it's tested. I have used it many times. I have told others about it and they have had great success with it.

The ingredients :
Generally, bread recipes call for 3 cups of flour. For the first time, use the following measures, and if you want a 3 cup bread, just double everything.

- 1 1/2 (One and one half) cup of flour. You can use bread flour, all purpose flour or 100% whole wheat flour. Whole wheat bread will be denser and heavier, as is to be expected.
- 2/3 cup water - but if you are using 100% whole wheat flour you will need 3/4 cups of water. Don't worry about the temperature of the water, just use regular water.
- 3/4 tsp table salt
- 3/4 tsp yeast (active dry or instant yeast)

Nothing else, this is as pure as bread can be (except of course breads using starters that catch air-borne yeast). Neither sugar nor fat of any kind is needed.

The first thing to note here is, the amount of water is way higher than recipes that require kneading. That's right, there is no kneading in this recipe, in fact so much water makes kneading impossible. We are relying on higher hydration to do the work for us. Apart from eliminating the kneading, high level of hydration will also give us soft, open crumb with big holes - typical of what is often called as an "artisan" bread.
In a large glass bowl (don't use plastic/metal) stir together flour, salt and yeast.

 Add all the water to it.


Using a big spoon, keep stirring the dough for a couple of minutes. You won't be able to do that with your hands. The dough will be very sticky. As you begin, it may feel too wet or too dry, but don't worry. Just work the sides of the bowl to keep the dough in one lump. All you are trying to do is to eliminate any dry spots. It won't take more than 2-3 minutes. That's it. The dough will look like a very sticky lump.


Cover it, and keep it away from sunlight for about 4 hours. Don't worry about the exact duration. The rising won't be done in less than 3 hours, and won't need more than 5 hours. Use the following photos as a guide to decide when it's time to bake.

Halfway during the rising, it will look something like this.
 
When the dough starts looking bubbly like this, it's ready for baking. By this time, the dough would have tripled in size, if not more.

Liberally sprinkle a cookie sheet with flour. You can use a foil to line the sheet, I prefer parchment paper.

Now, very gently pour the dough - which will look like a thick batter - on to the sheet. Just remember to not force the dough, or you will punch it down. We want to protect the air bubbles as much as possible. Tilt the bowl, and let gravity do the work for you. If you have to, just nudge it around edges. But do NOT scoop it out. Do NOT press it. Sprinkle it with flour.


Once it's on the sheet, let it be. Don't try to shape it. Our bread is very similar to ciabatta - which literally means "carpet slipper" in Italian. The only drawback of higher levels of hydration is difficulty in shaping. I would recommend that you don't try to shape it at all. Don't even score it. If you are trying out for the first time, you will almost surely punch it down while doing so. Just keep it simple, avoid the work and as a bonus, you will get a nice bread !

This may look flat - but trust me, you will get a nice oven spring once the dough is in the oven. For first few minutes, the warmth of oven and high water content will send the yeast into a frenzy and before it gives up it's life as the temperature of dough goes over 200, it would have secured you a very airy crumb.

Pre-heat the oven at 425 F. Ovens are different. But you cannot bake it below 400 and anything over 450 is too high. If you have to adjust later based on the result, be within that range.

Put the sheet in oven and bake for about 22 minutes. Again, it won't be done in 20 minutes, and over 25 minutes, it will be almost over baked. Whole wheat may take 25 minutes, but not more.

During baking, the bread will rise and spread. It won't be a super-tall loaf. It needs room to increase its size sideways, so don't bake it like a cake in a pan to give it shape - this needs to be a free standing loaf.

Once it's baked, remove it from oven and let it cool on a rack for at least 20 minutes. It's tempting to just cut it and eat it, but you have to let the steam, that's trapped inside, complete its job.

Use a sharp serrated knife and try not to squeeze the bread while cutting. Best time to cut is when you are ready to eat. This bread will stay for a couple of days, but it will start to dry out once cut - remember there is no oil to keep it soft.

This bread is perfect with an Italian menu and for many Indian dishes like "Paav-bhaji" and "Usal Paav" etc. It will be fresh, homemade, without any chemicals/preservatives and healthy. And very simple to prepare.

If you have any questions or need to make some changes or need variations, let me know.

Changeling

Movie Review : Changeling
Released : 2008
Director : Clint Eastwood
Genre : Drama
Starring : Angelina Jolie, John Malkovich
My Rating : 8 out of 10

Clint Eastwood has established himself as a foremost contemporary director with a distinctive style. With well developed characters, a strong focus on the story and a very deliberate pace, his movies capture our attention and never let it go. Even when the movie is over. "Changeling" is no exception.

The movie is based on a true story. In late 1920s, a single mother (played by Angelina Jolie) is living with her only son, about 10 years old. One day, her son goes missing. Most likely kidnapped. The police claim to have found him. But when the boy is returned to the mother, she claims it's not her son. Why do the police pressure her to accept the boy as her son ? That's not hard to figure out, as the movie shows how corrupt the cops were. But what happened to her real son ? And will the police accept their mistake and find the real son before it's too late ?

That's the real focus of the movie, and hence I won't divulge any further. The movie takes its time in developing the story. But remember, true stories do not have neat fiction like endings. So more than the ending, how the movie reaches there is important. The story progresses on at least 2 lines. The struggle against the corrupt police system, and the real investigation that becomes more and more disturbing as it progresses.

These 2 lines eventually merge together. Neither one is pleasant. Eastwood doesn't take any easy routes and no parent can remain unmoved by what gets discovered in the investigation. This movie is not for the faint of the heart.

Everything about this movie is top class. Great direction, great script and superb editing. John Malkovich does a perfect job in the role of a pastor supporting Angelina Jolie's fight. All other actors perform admirably, especially the alleged kidnapper (played by Jason Butler Harner) is evil personified.

Angelina Jolie received an Oscar nomination for this role, and I happen to disagree with it. She did a good enough job, but I wasn't wowed by it. A role like this offers a lot of scope to the actor to be great. Her acting was very good, but should have been great. That and the length of the movie, stops me from giving it a full 10.

This is correctly rated as R, and kids should be kept away from this movie. For serious movie buffs, this is highly recommended.

My tomato is bigger than yours

Had a nice crop of tomatoes this year. Some of them were quite big. The following is a tomato, NOT a pumpkin - it's bigger than a red delicious apple. Wish they had a tomato competition like they have for pumpkins. Maybe I should carve a tomato for this year's Halloween !

Your next crisis

This century has began with a series of crisis on the economic front. From the dot com bust to the housing bubble to financial crisis and to sovereign defaults.  I think the US Govt debt - as bad as it is now - is dwarfed by the political and economic crisis that will be brought upon us by the financial disaster waiting to happen at state levels.

This is NOT something that will happen in distant future. It's going to happen soon. See this story on Bloomberg ...(emphasis mine)
California, which has the largest U.S. public-pension fund, faces liabilities that may exceed its annual state-tax revenue fivefold within two years unless lawmakers rein in benefits, according to a study.
To keep their promises to retirees, the California Public Employees Retirement System, the biggest plan, the California State Teachers Retirement System, the second-largest, and the University of California Retirement System may have combined liabilities of more than 5.5 times the state’s annual tax revenue by fiscal 2012, according to the study released today by the Milken Institute. Levies are forecast to reach about $89 billion in the year that began July 1. 
... 
This will not be just a financial problem for the pension funds. This will be an economic issue due to tax implications and a polarizing political issue with potential social unrest. Why ? Because every California resident - is either paying for these pensions or receiving these pensions. A neutral stance is unlikely to be available :-(

California is not the only state in this situation. And this hasn't even started catching the attention of the masses. I have no idea how this is going to play out, but I suspect, it won't be pretty.

The "Lara Lappa" girl

This song was played often on TV when I was growing up in India. It's from the comedy movie "Ek Thi Ladki" (released in 1949), but who really was that girl ? The tune is catchy, Lata's voice is very sweet, the lyrics are funny and the actress is cute enough to make you ignore the outdated and forced acting style. But what happened to that beautiful face ? I could never gather much information about the actress herself.



Till man invented internet, of course. I found all the information I was looking for, at UpperStall.
From being the heart throb of India (being known as the 'Lara Lappa girl' at her peak) to begging at a film function in the 1980s in Pakistan for money to marry off her sister's daughters, Meena Shorey's is the classic riches-to-rags story one often finds in the filmline, the world over.

Much more information at the link. Looks like a nice site.

Quants



Book Review : The Quants
Author : Scott Patterson
Released : Feb, 2010
My Rating : 3 out of 5 stars

The complete title of the book is "The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It".

The financial collapse of 2008, has generated a lot of information on many facets of Wall Street via books, news articles and TV documentaries.  This book focuses on the secretive world of "Quants", or hedge funds primarily using quantitative analysis as their investment strategy.

The people who run these funds are not in the tradition of Warren Buffet, rather they are Math wizards. They depend on their statistical analysis skills and a deep understanding of probability theory to manage huge sums of money. Their models are built on massive number crunching, rather than fundamental economic analysis.

How different it is than traditional investing philosophy ? How did these funds come to manage such huge sums of money ? Who are these people ? How did they do it ?

The book tells us, that it all started with Ed Thorpe. He literally wrote the book on winning in blackjack, "Beat the dealer". He then extended those ideas about using probability, computer modeling and statistical analysis to beat the stock market - the grandest of all casinos.

Calling Wall Street a casino, is not just a cliché. Many of these quants are very good poker players. Peter Muller has won many poker tournaments. They are obsessed with gaining a complete control over risk, not in just managing it. Understanding probabilities and positioning for various outcomes is what they excel at. In that sense, there is a lot of common mathematical ground on which strategies for both poker and trading can be built on.

This is a fascinating story to say the least. Part history, part rough biographies, and part commentary - the book presents a lot of information in a very reader-friendly style. In spite of the heavy sounding title, this book makes for a very light entertaining read - the target audience is general public like you and me.

The author, Scott Patterson is a journalist, and that style is obvious. Very readable, but often time feels very superficial. There is a lot of research done on the historical aspects, no doubt, and it's very informative. On the other hand if you are interested in finance/investing, you will most likely not encounter anything new on that aspect. I also found the order of presentation a bit distracting. It's almost chronological, but shifts back and forth between different people and the transitions are not smooth.

I can definitely recommend this book to everyone. But it left me wanting for more, and only half satisfied. Is the author blaming the quants for the financial collapse ? Of course they played a part in it and the over-reliance on models is one of the main culprits. But how much blame goes to quants ? What about the over leverage in the entire system ? And outright fraud at all levels starting from borrowers to mortgage originators and to all the steps in securitization. Not to mention the bad regulation (repeal of Glass-Steagall) and failure of Federal Reserve. This context is not mentioned at all.

If you keep that in mind, I think you would enjoy the book.

Movie Review : The Trigger Effect

Movie Review : The Trigger Effect
Released : 1996
Director: David Koepp
Genre : Thriller
Cast: Kyle MacLachlan, Elisabeth Shue
My Rating : 6 out of 10

While browsing the TV Guide, I came across this movie - it had an interesting enough synopsis, that perked my curiosity enough to record it on the DVR and watch it later.

Which movie would you prefer to watch about some Aliens attacking planet earth ? Is it "Independence Day" or "Signs" ? (Maybe for you the answer is "neither", but that's beside the point !) Do you prefer loud action ? Or do you prefer to see how ordinary people would react to extra-ordinary circumstances ? That answer should decide if you want to try "The Trigger Effect" or avoid it.

The situation in this movie is not post-apocalyptic, but has certain resemblance to it. Here a mysterious power outage throws a family's life in disarray. The movie does not explain why exactly the outage happened, and that's fine by me. What it tries to do is to show how common people would try to cope up with complete lack of electricity, no telephone, no radio/TV, no communication of any sort. This is 180 degrees opposite of "Mad Max 2". People in this movie are close to a breaking point and there are indications that if power is not restored, there will be anarchy. But everyone's trying his or her best to hang in there.

This is the kind of treatment I like. And if the movie is willing to go off a beaten path, I am more than willing to take a tolerant view of it. So while such a movie may seem boring to some, I am drawn to any such attempt of "new treatment". In spite of such biases, the movie was not entirely satisfying to me.

Generally this happens because of a hasty, contrived ending. The problem here is quite opposite. The latter half of the movie is quite tense and well crafted. The issue I have is with the setup. It takes forever for director David Koepp to establish the characters and their relationship. And even then, we don't really learn much about them. So chances are many viewers would start yawning and switch off before the 1st quarter of the movie is over.

Fortunately, there is no preaching about how over-dependence on the technology is bad. The movie is far away from being a Sci-Fi. I think the movie is incorrectly labeled as a "thriller", and "drama" would be a better genre for it.

I have very mixed feeling about recommending this movie. It's rated 'R' and is not for kids. It's definitely not a waste of time, but I don't see any compelling reason to go out and rent it either.

if Furlough then Salary++ ;

The Law of Of Unintended Side Effects, strikes again.

California Watch reported that :
Rather than receiving a 15-percent pay cut as intended, hundreds of state managers and other high-level workers brought home more money than usual during some furlough weeks thanks to an obscure federal labor law, a California Watch review of state records has found.
During furlough weeks between February 2009 and April 2010, state departments paid at least $1.6 million in overtime to salaried state workers who are not typically eligible to receive it, according to data provided by the state controller's office. At least 14 employees took home more than $10,000 in overtime payments during that period.
The payments were allowed because during furlough weeks, federal law requires the state to temporarily classify most salaried workers as hourly employees so their pay can legally be reduced.
But that shuffle has a side effect: It makes employees who are typically exempt from overtime rules eligible for a rare opportunity to collect the extra cash.
Ironically, the department that paid the most was EDD !
Of the three-dozen departments that paid at least some overtime to exempt workers, none shelled out more than the Employment Development Department, which paid more than $488,000. The department is charged with running California’s unemployment programs, which have been swamped in the down economy.
Department spokeswoman Loree Levy said demand for unemployment benefits and information technology projects within the department led to the overtime, which she said was closely monitored and approved.

Be happy, your tax dollars are working overtime !

Raavan

Movie Review : Raavan
Released : 2010
Language : Hindi
Director : Mani Ratnam
Starring : Abhishek Bachhan, Aishwarya Rai, Govinda
My Rating : 1 out of 10

My only reaction to "Raavan" by Mani Ratnam, is "Hey Raam !"

I have loved many of Mani Ratnam movies. "Bombay" is on my list of best movies. So it makes me very sad to say that, this movie is not worth writing any review. Simply avoid it and send your ticket money to Mani Ratnam as a "retirement gift" and hope he gets the message.

Eureka Man



Book Review : Eureka Man
Author : Alan W. Hirshfeld
My Rating : 2 out of 5 stars

The complete title of the book is "Eureka Man: The Life and Legacy of Archimedes".

I visited Nehru Science Center as I high school student. I still remember my astonishment after seeing the "Archimedes Screw" to get water up from a low point. The simple ingenuity made me wonder, how could he think of that trick ? That was but one small achievement for the genius mind of Archimedes, who is considered along with Newton and Gauss as the greatest mathematicians ever.

But he was much more than a mathematician. Among many other things, he was a physicist,  the greatest engineer of antiquity, an inventor and also a defense strategist for his native country Syracuse. His siege engines against the Roman army made him a legend for centuries. Galileo called him a super-human, Newton used his geometric diagrams to draw geeky graffiti, and countless other geniuses were awe-struck by the achievements of one man's mind.

So, when I saw a book on him, I had to pick it up and read. Unfortunately I was sorely disappointed.

The book has 2 parts. First part, talks quite dryly about the life of Archimedes and some of his achievements. Of course, the Eureka incident is mentioned, along with his work on levers, value of pi etc. His war engines and historical context also get a decent coverage. Little else is covered. Neither parabola, nor the spiral gets any mention. There are some nice pictures and photographs. The explanations here are OK, but what's missing is the passion.

A much bigger second half talks about the discovery of the Palimpsest - the copy from antiquity of Archimedes' original book. As interesting as the story is, it's way too much detail for me. For someone who is interested in the story of historical documents, this may be fun. Just maybe, as although it is informative, it's hardly gripping. I was bored.

It's a short book and it simply fails to respectfully treat the greatest polymath we have known. It's a shame.

Is it all about Euro ?

Today the market broke many key levels (including the "devil's number") and is "officially" in the correction mode, at least according to CNBC.  Every journalist is saying the reason to be the trouble with Euro - which not so long ago was touted as the new reserve currency of the world. And once in a while, you would hear the mention of the cute acronym PIIGS. But is it really just about the ClubMed countries ? How about ...

1. UK and US having similar debt burdens ?
2. A very real possibility that China may crash ? How many empty cities can you build to pump up the economy ? The commodity prices (see copper and oil for example) have gone down - and it's not because of Europe, but concerns about China.
3. Most states in US are effectively bankrupt, and personal debt levels still very high.
4. The entire multi-trillion dollar web of interlinked derivatives still needs a lot of unwinding.

All this points to deflation and almost no growth prospects, which means P/E ratios for US equities are still very high. That's the reason IMHO for the on-going crash. Of course you will not hear this on CNBC - which can only tell you to buy on the dip so that their real masters can make you the bagholders.

Anand retains the crown !

Today, Vishwanathan Anand won the 12th and final game of the match against Bulgarian Topalov, to retain the crown. This was an incredible match and deserved the dramatic finish it had today.

It didn't start that well for Anand. He first had trouble reaching the venue in Sophia, Bulgaria as the volcano eruption in Iceland had stopped all the flights. Then he lost the very first game due to a blunder. He bounced back immediately by winning the next game and equalizing the match. That was followed by very high level complicated chess by both the players - undoubtedly the 2 best players in the world today.

The match was tied before today's game. Anand won it as black. Today, he was definitely helped by Topalov, who committed a crucial blunder. But it wasn't all easy after that and Anand had to play precisely.

Overall, both players played terrific chess. The result is fair, as Anand definitely played better both technically and psychologically. His match strategy was generally better than his opponent. Even today, he avoided a draw in an equal position and kept on playing, applying pressure. This battle of nerves was over just 10 moves later, when Topalov self destructed himself. Then a desperate attempt to save the game simply did not work against the calm genius of Anand.

It's been 20 years since Anand has been at the top of the chess world. It's a phenomenal achievement. In the first half, he was second only to the greatest player in the history of chess - Kasparov. After Kasparov peaked and retired, Anand has been the overall best player. Kramnik and Topalov have had their peaks, but Anand's the only one to have the continuity.

The revolution he has caused in Indian chess is no less remarkable. He did it on his own, without any help from Indian Government, against the mighty coordinated schools of Soviet and Eastern European players, in spite of the dirty politics at the top of the chess world. And still, he is the same humble player with easy manners – which has won him fans all over the chess playing world. Just because of the inspiration provided by him, India now has a growing base of talented chess players. This game does not require strong physique and ton of money, like most other sports. It's all in the brain, of which there is no shortage in India. So one day, it's quite possible that India becomes the dominant country in chess. If that happens, Anand deserves the lion's share of the credit.

Mendeleyev's Dream



Book Review : Mendeleyev's Dream
Author : Paul Strathern
My Rating : 4 out of 5 stars

The complete title of the book is "Mendeleyev's Dream: The Quest for the Elements", and frankly it's a bit misleading. This is neither a biography of Mendeleyev (that's how author chooses to spell his name) nor is it any introduction to the periodic table. It's a history of Chemistry that begins of course with Greek philosophers, takes interesting detours and ends abruptly without really talking about the periodic table.

As a book on history of Chemistry, it's quite fun to read. In a relatively short book, the author manages to cover many famous scientists, their life stories, their achievements and their impact. Most of it is touching and captivating. The personalities cover a wide range of spectrum. From many famous scientists like Lavoisier, Cavendish to not so well known (at least to a layman) Paracelsus and Scheele. The anecdotes about them range from weird to tragic. The zigzag development of theory covers "Earth, Fire, Air, Water", alchemy, phlogiston to near modern chemistry. This is a very broad scope.

In addition there is a lot of trivia packed into this book, and I mean a lot. I tremendously enjoyed these additional tidbits of knowledge thrown at me.

For good or bad - (and IMHO more bad than good) - there is a lot of opinionated commentary thrown in. I cringed many times while reading the book. Some views get dismissed as religious hocus-pocus, while some are branded as "the biggest blunder in human thought" ! These are admittedly shallow comments. It's akin to dismissing ancient thinkers as stupid, because they thought the universe was earth centric. Without proper understanding of the prevailing social context, available tools for scientific experiments etc. it's simply wrong to make these judgments.

Another drawback is the lengthy detour about scientific revolution. I would have preferred a shorter discussion and more attention to actual periodic table, which was the topic suggested by the book's title !

Overall, this is a very fun book to read. It's also a very good book for high-school students who are really interested in Chemistry and want some historical context.

Pleasanton Murals

I pass this mural in Pleasanton every day on my way to work. There are always cars parked in front of it. On a Sunday morning, I got a chance to take a few photos of the complete drawing - just at the same time, when someone else was also taking a photo :-)


Look closely ..



The mural without the 3-D illusion effects is nice on its own ..
