Pictures worth pondering...


The latest report,  known as “Trends in Maternal Mortality”, is jointly released by WHO, the United Nations Children’s Fund (UNICEF), the United Nations Population Fund (UNFPA) and the World Bank
  • Women in developing countries are 36 times more likely to die of pregnancy-related complications than women in developed nations.
  • Developing nations accounted for 99% of all maternal deaths, with 57% in sub-Saharan Africa and 30% in South Asia.
  • The study shows progress in sub-Saharan Africa where maternal mortality decreased by 26%.
  • In Asia, the number of maternal deaths is estimated to have dropped from 315000 to 139000 between 1990 and 2008, a 52% decrease.

Another passport episode

No, this time the experience is not from me, the guy who presumably has no right to speak up against Indian bureaucracy since I live abroad. This is from a successful entrepreneur from Mumbai.

Song and Dance

Have you ever heard a song, liked it and wanted to see the video of the song...? Sometime it turns out to be a mistake! Over the years it happened to me a couple of times. Some of the best songs are poorly portrayed on the screen. This one is the latest for me. I was so impressed by the poetic lyrics of the song, it drove me to hunt for the song on youtube only to become disappointed by the way the song was picturized. I don't know what is the best way to bring on screen a song so beautiful as this one, but it ain't this way. Well, close your eyes and listen to the song first and then watch it the second time, you will know what I am talking about.




If you have any such experience, please feel free to share. I almost feel like we should collect such beautiful songs and remake them just to do justice to the poetic lyrics.

This is what it has come down to now?!

I knew water problem was bad in India. IMHO this is an awful solution to the problem. It makes India more dependent on foreign resources especially such vital resources. This is not a sustainable solution. Instead we should explore cheaper desalination plants to convert sea water into usable water.



""Like so many other commodities, water is going global. A number of recent news articles have described water as "blue gold" and the "the oil of the 21st Century". Entrepreneurs are responding to supply and demand imbalance by seeking ways to transport water from countries and regions with plentiful amounts to areas in short supply," wrote Terry Anderson and Clay Landry of what is now known as the Property and Environment Research Center way back in 1999. "John Hayward, a water expert for the World Bank, commented that 'water will be moved around the world as oil is now.'"

Carnatic music lessons

There are many sites with Carnatic lessons. I find this one to have an excellent coverage of foundational materials.

http://www.ecse.rpi.edu/Homepages/shivkuma/personal/music/varnams/index.html

With materials like this and a local music teacher as a coach, students anywhere can set sail into the world of music.

Speaking of music, here is an excellent analysis of Ilayaraja's contributions to popularizing Carnatic music in films.

Does everyone like you?

everyone...?! Here is a related question. Have you ever been in a position where you have to make decisions for or on behalf of others? Here is an explanation.

'Leading' is making decisions.
Making decisions is choosing between difference choices.
Choosing is rejecting some choices.
Rejection affect people who stand to gain from those choices.
People who lose by your decision usually don't like you! :-)

In an ideal world where everyone is equally smart and appreciate the rational behind decision making, everyone will like everyone else in spite of any loss to their income, prestige, fame, etc. Our world is far from ideal.

So if you are a leader, not everyone likes you. That is guaranteed.

Eating with hands!

Eating with hands is somewhat uniquely Indian. While people around the world invented tools like spoons, forks, chop sticks, etc, we are comfortable eating with our hands. What's up with that? We are bunch of smart people why didn't we invent a tool? We do use different types of spoons for cooking. So why not one for eating?

Last winter I realized an answer to this question. Even if the food is served hot in the plate, when the temperature outside is freezing, very quickly the food becomes cold. If you eat with your fingers in the freezing cold weather, you fingers start to hurt by the time you finish eating! It is pretty uncomfortable. Cold food in mouth goes down without much discomfort. But touching the cold food is not a comfortable feeling. So if you can pick up the food with a tool and drop it in your mouth, that serves as a comfortable meal. In India, we are used to warm weather all around the year. If the food is hot, let it cool for a few minutes and you can pick it up comfortably with your hands to feed yourself. So there is no need to invent a tool!

Incidentally, we have food like Dosa that is difficult to eat with a standard tool like spoon or fork, especially if it is crispy. Either we have to invent a Dosa eating tool or make bite size Dosas just like mini idlies.

People eat sandwiches here with their hands. So it is not completely an alien behavior. The thing that beats me is why the fast food sandwiches are so big that it never fits in your mouth. Eating a sandwich is a scene. You have to wide open your mouth to take a bite. Restaurants boost showing their sandwiches with a huge stack of stuff layered with some bread or bun on the outside. If I am going to pick up loosely assembled stuff to eat, I would rather pick up a bite size sandwich piece and eat it at once. Oh well.... perhaps we need to modernize our food and eating tools...?! :-)

Wisdom and Instinct

The good and bad in life are not black and white as in the movies. They are shades of grey. It is only after the fact, well into the future, you realize if something turned out good or bad. Randomness influences life in a big way. So conventional wisdom is subjective and sometimes one has to completely ignore it. Here are few examples of how some famous people ignored their stumbling blocks and got ahead to make history simply by following their instincts.


  • "Children just aren't interested in Witches and Wizards anymore." - Anonymous publishing executive to J.K. Rowling, 1996.

  • "Who the hell wants to hear actors talk?" - H. M. Warner, co-founder of Warner Bros. 1927.

  • "There is no reason anyone would want a computer in their home." - Ken Olson, Founder of Digital Equipment Corp., 1977.

  • "We don't like their sound, and guitar music is on the way out." - Decca Records executives rejecting the Beatles, 1962.

  • "You better get secretarial work or get married." - Emmeline Snively, Director, Blue Book Modelling Modelling Agency, to Marilyn Monroe in 1944.

  • "The horse is here to stay but the automobile is only a novelty, a fad." - The President of the Michigan Savings Bank advising Henry Ford's lawyer not to invest in the Ford Motor Co., 1903.

  • "I'm sorry, Mr. Kipling, but you just don't know how to use the English language." - The San Francisco Examiner, rejecting a submission by Rudyard Kipling in 1889.

  • "The Americans have need of the telephone, but we do not. We have plenty of messenger boys." - Sir William Preece, Chief Engineer, British Post Office, 1878.

  • "The world potential market for copying machines is 5000 at most." - IBM, to the eventual founders of Xerox, saying the photocopier had no market large enough to justify production, 1959.

    Fascinating Facts - The floating Earth

    As you may know, Einstein's general theory of relativity completely changed the way we think about space and time. Instead of objects sitting in space as time tics and tocs, objects distort and interact with space and time together. The theory predicts that earth, stars and other galactic objects bend the space around them.


    NASA’s Gravity Probe B satellite proved the theory's predictions.

    Leaf blower cleans dryer vent

    If you understand the title, skip to the second paragraph of this article. Unlike in India where there is abundant sun throughout the year to dry washed cloths outdoor, in the North East United States indoor cloth drying equipments are a necessity. Washing machines and dryers are standard equipments in every household. Natural gas or electricity is used as heating source for the dryers. Hot air is blown in a chamber where wet cloths spin. The air absorbs moisture in the cloths and leave out of the equipment and the house through an exhaust pipe. Duct work to let the hot air exit out of the building is part of standard plumbing. When clothes dry at high temperature most fabrics leave behind fluffy cotton lint in the dryer and the exhaust vent. One of the leading causes of house fire in the U.S is the fire caused by overheated dryer vents.

    Recently, I was reminded of a house fire of a colleague because of clogged dryer vent. It was time to cleanup the dryer vent since I haven't done that ever. There are ton of products out there that are meant to clean the dryer vents. I picked up one of those and found it was pretty inefficient. Brush attached to a long flexible cord goes hardly two feet inside the vent. Beyond that it is impossible to push the brush since there is no strong hold and the cord bends instead of pushing the brush inside the vent. Then I tried using the vacuum cleaner. Again I could clean up about two feet on both ends of the vent, but much of the lint is in the middle around the bend of the vent, I could see it with a flash light. After much frustration, I was about to give up.

    In a flash of thought, it occurred to me to try using my leaf blower from one end. Viola! That worked like magic

    The blower pushes the lint in the vent from one end and moves it out through the other leaving the vent nice and clean. The job was well done in few seconds. Not knowing how efficient this will be I ended up having to vacuum the inside of the house near the dryer where the dirt piled up. Next time I am planning to tie a plastic bag or something on the dryer end of the vent to reduce the mess. Or perhaps I should try blowing air from the dryer end.

    Well, turns out Leaf blowers are much more powerful compared to the dryer fans. Long time back I learned that with the right tools, any work can get done with much less effort and incredibly well. Apparently, sometimes we have to find the right tool ourselves.

    Winter and Ear Infection

    Right from the childhood I have suffered from ear infections during winter. Had my tonsils removed long ago. Yet, I had to suffer through every winter at least once, sometimes more than once when the temperature remains below comfortable level. I have knocked the doors of many a specialists, internal medicine, ENT, family practice, etc. Once an ENT specialist wanted to eliminate the possibility of a tumor growth inside nostrils and subjected me to a thin tube insertion with camera and light on one end to look inside. Nothing came up out of norm. One treatment option went like this. We should put a hole in the ear drum and fix a pipe to drain the fluid that builds up around your sinus during cold temperature. This tube will be a permanent artificial fixture inside the head and prevent ear infections! Well, I wasn't sure I wanted to go for that. An internal medicine doc prescribed a nasal spray that you point in an oblique angle inside the nose and spray twice a day. A side effect of that was that it makes you addictive to using it for ever. Other than that I didn't see it work at all. And the worst of all, every time I suffered from the ear infection, I had to be on one full dose of Antibiotics that ran for 30 days a course. That means, for more than half of winter every year I was on antibiotics! The antibiotic is not a preventive medicine; it did not reduce the pain, it just helped prevent further infection, I guess. So, this gave me one more reason to hate winters!

    Early this winter, I was at a local Target (a supermarket chain) and spotted a ear muffler. It looks something like the figure shown.

    Every time I went out, I wore the muff. It worked like magic! Apparently, my body is sensitive to cold air getting inside the ear canal and reacts by pushing the ear drum from inside. The pressure develops into prolonged pain, redness in the inner ear and thus infection. As soon as the ear muff blocked cold air from getting inside the ear canal, it relieved me of my long lasting problem! What a simple world, that we complicate by over thinking. For the first time in many winters, I am free of ear infections this year and it happened just by pure luck! I am so thankful I found this little contraption that has improved my quality of life tremendously.

    Can death be treated?

    Can we treat someone out of death? Granted we don't know when the moment comes. But when an individual is old, lived a full dignified, happy life, laboring in the last moment of life, should the individual be "treated" with ventilator, dialysis, blood transfusion, CT Scans, heavy dose of medications, etc.? The cardiologists, the neurologists, the nephrologists and other specialists give their expert opinion on the condition of the individual body part heart, brain, kidney etc., Life inside is fighting back to make an exit..Unfortunately this situation is not unique to our honorable leader Mr. Jyothi Basu who is in his death bed right now.

    A Doctor comments the following on the condition of Mr. Jyothi Basu in The Times of India forum.
    "He is 96 years old. The life expectancy of someone born in India in 1914 would have been less than half of that, and almost 100 years later, most Indians (and most humans) don't live that long. While the media is reporting all the "heroic" efforts the doctors are making, and all the technology they are throwing at a frail elderly man, nobody seems to care to ask if he would have approved of his body being put through all this invasion and indignity. He has multiorgan failure over age related decline in organ function. An elderly person in this condition is unlikely to recover his previous cognitive and functional status. Isn't it time to allow natural death?"

    With the help of modern medicine, we take extraordinary measures to prolong life at all costs. Our hospital Intensive Care Units (ICUs) have made death invisible even to the closest family members. The patient almost always has no say on how they want to pass. As a culture, we are growing ignorant of letting go our near and dear gracefully and with dignity.

    Tamil poet கவிப்பேரரசு வைரமுத்து (Vairamuthu) in his collection of poems "இந்த பூக்கள் விற்பனைக்கு அல்ல" writes as follows in the poem "வேண்டுவன"

    "...
    கடைசிவரை
    சுயமாய் நீர் கழிக்கும் சுகம்
    உறக்கத்தில் உயிர் பிரியும் வரம்"

    (The wants - Being able to urinate without aid; to die in sleep)

    Even if one is not lucky to pass while asleep, wouldn't it be wonderful if one remains conscious, meets with all loved ones to say that they love them and they forgive them, labor through the dying process, just as it happens during birth and finally depart?! Wouldn't it bring a sense of closure on a life, not only to those who die, but also to those who live to remember them? Is there is a better way to end a great journey of life? Should a life go in the dark, alone, unconscious and surrounded by strangers? I have seen one too many to go the same route. Now we see the drama being played out in the media for Mr. Jyothi Basu. May him rest in peace when the time comes. India will miss a great leader of the people.

    Decibels and Octaves

    Happy New Year everyone. It has been a while since I blogged last. Sometime back I started learning Piano. That was my first introduction to world of music - theory and composition. As you may know already, a Piano has several white keys with black keys spread between them. The arrangement has a repetitive symmetry to it, even a casual observer would notice. Little did I know that there were fundamentally just 12 keys - 7 white and 5 black - collectively called as an 'octave' and this set is 'kinda' repeated over and over throughout the piano. Not quite repeated, but a key in one octave will emit a sound of frequency exactly twice as that of the corresponding key in the previous octave. And as for the relationship between keys within the same octave - it is quite simple - since you do not want an abrupt transition when you go from one octave to another, the 2nd key in an octave has a frequency (f2), that is the frequency of the 1st key (f1) multiplied by 12th root of 2. i.e. f2 = f1*(2^-12). This is so that automatically when we reach the first key of the next octave, which can be referred to as (f13), we have f13 = f1*(2^-12)^12 = f1*2 - Thus 1st key of next octave has frequency twice as much as that of the 1st key of this octave - therefore no abrupt transitions in frequency and at the same time an octave is doubled in frequency as it is repeated over.

    Since the intention of this blog is not to give you a lesson in music, let me get to the point. When I first heard the term 'octave' while learning Piano, I didn't think about it too much - but it did ring bells in my subconscious mind. One day I was working at my office dealing with a measurement which used log2. When I was comparing one value with another one, I was writing down in my record book, "2nd measurement is one octave higher than the 1st one" - oops, 'octave'!! Now I remembered - in engineering like we use 'decibels' as units when we refer to a log10 value, we use 'octaves' when we use log2. The etymology of 'decibel' is known - it is from Graham Bell, an unit often used to measure sound as Graham Bell invented the sound device of telephone. But in college I always wondered where 'octave' came from - because what has log'2' in common with number 8 ('oct'ave)? Well it is all clear new - every '8'th white key in a piano will belong to the next 'oct'ave, that will have a frequency 'twice' as much as the 1st white key. In other words, if we take two white keys of frequencies fx and fy and compared them logarithmically, and if log2(fy/fx) = 4 then one white key is 4 'oct'aves away from the other. Well, people were measuring sound long before they even heard of electricity - I guess they used the same units they used for sound, which they were familiar with, when they started measuring electricity first.

    After all that being said, I still have no clue why an octave contains 12 keys (why not, say, 14?). It might hit me someday!
