Kill boredom

"Necessity is the mother of invention" - so goes a saying. Must be true or else the world would not have got so many wonderful inventions. Internet is one such invention which not only kills boredom but also provides a sea of opportunities to learn,earn,network...
When pushed into a sea of boredom, many of us try to explore ways to get out of it. Volunteering, reading, music, gaming, etc etc. Or some of us might end up in internet networking sites. Networking sites are available today in different forms - social networks like orkut, myspace, facebook, professional networks like linkedin, other sites like Shelfari where people share their hobbies, sites like twitter where you let people know what you are upto. Then we slowly move on exploring other arenas. Some hit up with Swagbucks; an upcoming search engine which rewards for your searches. Interesting! With 50,000 fans in facebook, 20000 followers in twitter and much more, the engine is progressing everyday. There are also lot many sites like irazoo which are equally good in rewarding searches.
Another field which pays is online surveys. There are lot of sites like surveyhead, greenfield online,etc which pay for the surveys we take or for clicking the ads displayed on the sites. These rewards may be peanuts but something is always better than nothing...so if you have lot of free time, just give a try .

The stock market swing

A stock market is as enigmatic as a woman's mind ; deep and unpredictable. Even millions of analysts around the world try to predict its movement but have seldom succeeded. At times they rule and drive a country's economy; sometimes bringing wealth, sometimes taking wealth. A game where the money lost by someone is the money gained by another. The size of stock arket is abot $40 trillion, about 40 times the size of Indian economy.

Inspired by the enormous opportunities of wealth creation offered by stock markets, everyday retail investors park their money in stocks. Those who do not have the patience or time to track the market, take advantage of the mutual funds who professionally manage our money by investing in stocks. The recent hullaballoo being SIP (systemmatic investment plans) where every month a fixed amount is invested in stocks by the fund manager. No wonder that these plans received good recognition from retail investors as it takes advantage of the ups and downs of market. The SEBI, as a moderator, keeps changing the rules of the game now and then; latest being abolishment of entry load (a fee for puting money in a mutual fund).Good news for people who have burnt their fingers in the past bear run; analysts have predicted that markets are going to turn bullish again.
Commodities often rule the world economy. Steel, which once commanded the economy has lost its sheen in the current decade and has given way to oil. Oil bonds, which usually shows a negative correlation with equities (high oil price leads to high transportation, producion and operating cost for companies and hence reduced corporate earnings), are showing a positive correlation surprisingly. If we look at the recent bounce back in the market, oil price has also rallied parallely; meaning they both have gone up together. There is also a good demand increase in the market for oil as well as for equities.Hence there is no hard and fast rule in a market; after all if there is one there will not be any losers?
There are different ways to analyse a stock . The most common being:

- fundamental analysis which uses the company's financial,business,market,managerial strength to evaluate the value of a stock
- technical analysis deals with predicting stock movement using charts, graphs and patterns

All these tools will guide and give a fair idea about a scrip's performance; however there is no tool to find the certainity of a stock's movement. Blue chip (popularly traded stocks) are the favourites of low risk preferes, mid caps are preferred by moderate risk takers and small caps are preferred by high risk investors. It is always good not to put all your eggs in one basket but to have a combination of stocks in a portfolio.

Too much of anything is good for nothing; a rule of thumb is that an ideal portfolio is something which has about 15-20 different stocks and not more than that with an ideal mix from various industries, risk level and .
"A rupee earned today is worth more than a rupee earned tomorow". So utilize the magnanomous opportunities offerred by equities in various forms viz. mutual funds, derivatives, stocks and add wealth because higher the opportunity cost, higher will be the returns expected.

Hava Nagila...

Recently I happened to watch Usha Uthup's interview in television; what an amazing lady! In a period of classics, she broke all convetional music forms and emerged as a 'pop queen' having sung in all 15 Indian languages and 12 foreign languages. Neither she has a mellifluous voice nor has a professional training in music; yet she managed to twinkle in the world of music through her ever cheerful attitude and a magical smile that brings joy to the listener! However this post is not about her but the song she sang in the interview.
Hava Nagila- the Hebrewian song of joy! If you have seen Tamil movie 'Mozhi', you would have come across the song.Abraham Zvi Idelsohn is believed to have penned the song at the close of World War I to celebrate the British victory over the Turks. The song remained popular only in the Zionist cirles in United States and Europe .Lateron the American musicians who explored new avenues of music, turned to Hava Nagila for folk. Mambo legend Machito was one among them who brought Hava Nagila to American music. But one of the legends who made the world nod their head for Hava Nagila was Harry Belafonte! Following the success of the song in 1950s, he used to sing Hava Nagila always as the closing number for all his concerts and appealed the audience thorughly. However his performance at the Carnegie Hall in 1959 was the best selling record.The song then travelled through various decades, got remixed into all forms like reggae,punk rock, techno all across the globe among the Latinos, Africa, Macedonia...But still the original folk version remains the embodiment of Jewish song of celebration and joy!
So let us all rejoice along with Hava Nagila!

An interesting encounter

It was a cool spring Sunday morn. I had called for a taxi at 9am to downtown. The taxi arrived at 8.45 sharp ; at 8.59 the driver started honking. I am used to starting at Indian Standard Time 9am which is 9.10am. I murmured the impatience of the taxi driver and locked the door.A yellow cab was parked in front of the house. The driver was a man of 60,. He had green eyes and a bald head with strings of snow white hair here and there. He did not show the peace of mellow age; he was rather aggressive. His face and eyes had wrinkles; signs of a long journey in life. He wore brown sun glasses which he took out quite often. I gave him the print out of my destination with the route map. His impatience reflected in the way he sipped a mug of coffee which he carried. We were quiet for some time.

Finally I broke the ice asking about his familiarity with the route. He replied something carelessly and started cursing the traffic with an Arabic accent. I realised that the traffic was the culprit of his annoyance. After moments of silence, he started asking about my native country, how I landed up here,etc...and started narrating his story. He is a Palestinian software engineer, who fought in Yassar Arafat's army, who got sick of wars and homicide, moved to America for a peaceful life. A father of doctor & engineer sons and a daughter who is a teacher. He laughed saying that he had one wife; a surprise!
He was working on the data warehousing platform of a well-known American pharmacy.

Then why become a cab driver? It did not surprise me because in developed countries retired men who own a decent car, work part time as cab drivers and rent their cars. A fixed sum will be paid to the cab company everyday who in turn gives the addresses of callers.
May be these men drive for joy or for a living or for some pocket money or just to be active!

I could see the pride in his eyes when he said he owns a BMW Z4. He gave his card and informed that he will take people in BMW if they call him directly and not through the cab company; at little premium! Not a bad deal!

I was flabbergasted to learn that his father is still alive owning 4 six storied apartment complexes in Palestine. Retired from Palestinian navy, he is currently a maritime agent.

I was perplexed whether to believe him or not but sure he had no intention of lying or boasting his pride. Nor was he narcissistic.I felt truth when he talked about his joint family, beloved wife and children.I was moved by his concern when he gave hand sanitizer and warned about swine flu. He denied the tip I gave, saying that he drives for fun. Nevertheless, he made my journey fun and memorable with his stories.

Eventually he smiled and bid goodbye. He is flying back home for his daughter's wedding. His golden tooth sparkled in the sun.I should call him one day for a BMW ride !

Melakartha Raga index (Continuition to my previous post)

There are hundreds of ragas in Carnatic music.But the 72 Melakartha ragas (மேளகர்த்தா ராகம் ) are the mother ragas from which others are born. Such derived ragas are called as 'Jenya raga' (ஜென்ய ராகம் ). While the melakartha ragas have all 7 swaras, jenya raga may or may not have all 7 swaras.

A raga is defined by its aarohanam (ஆரோஹணம்) and avarohanam( அவரோஹணம்) which is nothing but the boundary of the raga from its lowest to highest swara.

E.g. Mohanam is defined as:

Aa : Sa Ri Ga Pa Dha Sa (Lowest to highest swara)
Ava: Sa Dha Pa Ga Ri Sa (Highest to lowest swara)

It is not necessary that aarohanam and avarohanam needs to have same swaras in the reverse order.

The following table shows some numbers assigned for each Sanskrit syllable.






If you closely look at each row, they follow the similar pattern in our Tamil/Hindi alphabets.

Row 1: ka, kha...til nya
Row 2: ta,tta till na...so on and so forth

So this is known as "KaTaPaYa"dhi Sankhyay( கடபயாதி ஸாங்கியை named after the first syllable in each row.

Now,

1.Pick out a melakartha raga from the list below E.g. Nattabhairavi
2.Refer திindex value of its first two syllables in the above table. For Nattabhairavi - 0 for Na and 2 for ‘tta’
3. Now interchange the numbers assigned to the syllables. It is 20 in this case; hence the raga’s number is 20!

So meet you soon in my next post with another interesting topic!

Some mathematical gimmicks in Carnatic music

Legend Dr.Balamurali Krishna once beautifully described how Carnatic music got its name. In Sanskrit, “Karna" means ear and "Ataka" means something which is amusing/pleasing.Therefore Karnataka Sangeedham aka Carnatic music is the music which is pleasant or amusing to our ears!

‘Sruti matha, laya pitha’ is the crux of Carnatic music .It means the drone and rhythm are mother and father to music. Subduing sruthi and laya is required to master the art.Carnatic music expresses these two by the way of Raga and Tala respectively.

Raga:

A Raga is a sequence of swara/sound. There are 7 swaras in Carnatic music known as Saptaswara ("Sapta" means seven in Sanskrit) which stand for:

  1. Sa -Satjamam
  2. Ri - Rishabam
  3. Ga - Gandharam
  4. Ma - Madhyamam
  5. Pa - Panchamam
  6. Dha - Dhaivadham
  7. Ni- Nishadham
While Sa and Pa are constants, the swaras Ri,Ga,Ma,Dha,Ni have further variants.
*Ri & Ga have 3 variants which are indexed as R1,R2,R3 and G1, G2, G3. Similarly Dha & Ni have 3 variants - D1, D2,D3 and N1,N2,N3. (Each variant has tongue twisting sanskrit names which I have ignored here for the sake of convenience)


*1-3 being biggest to smallest sound
*Ri,Ga,Ma,Pa,Dha,Ni are in ascending order of sound

Group I :R1,R2,R3, G1,G2,G3
Group 2: M1,M2
Group 3:D1,D2,D3,N1,N2,N3

*(Ri-R,Ga-G,Ma-M,Dha-D,Ni-N)

Each raga has the following qualities:

1.It has all 7 swaras
2.Within a group, the succeeding swara cannot have a smaller sound than its predecessor. E.g. N1 cannot follow D2 or D3. Likewise G2 cannot follow R3.
3.The swaras have to follow the regular sequence – Sa Ri Ga Ma Pa Dha Ni Sa and Sa Ni Dha Pa Ma Ga Ri Sa
4.Each raga can have either M1 or M2

And so,

Group I can possibly have 6 combinations:

(i)D1, N1
(ii)D1,N2
(iii)D1,N3
(iv)D2,N2
(v)D2,N3
(vi)D3,N3

Similarly, Ra & Ga will have 6 combinations.

Putting all these together,

1 (of Sa) x 1 (of Pa) x 6 (1 of the 6 combo of Ri & Ga) x 6 (1 of the 6 combo of Dha & Ni) x 2 (1of M1& M2) = 1x1x6x6x2=72 melakartha ragas
