TEDTalk by Sir Ken Robinson

Sir Ken Robinson’s TED Talk on education is brilliant and funny. Some quotes that struck me:

If you think of it, children starting school this year will be retiring in 2065. Nobody has a clue, despite all the expertise that has been on parade the last four days, what the world will look like in five years’ time. And yet we’re meant to be educating them for it. So the unpredictability, I think, is extraordinary.

If you were to visit education as an alien and say “What’s it for?”, I think you’d have to conclude, if you look at the output, that the whole purpose of public education throughout the world, is to produce university professors. Isn’t it? They’re the people who come out on top, and I used to be one. (So there!) And I like university professors, but you know, we shouldn’t hold them up as the high watermark of all human achievement — they’re just a form of life.

Wishlist for movies

I watch a lot of movies. Over the last year, I’ve watched over 250 movies (and read 50 books, but that’s another story). Other than making time to watch movies, my biggest problem is figuring out what to watch next.

The IMDb top 250 is a good guideline, and I’m running my way down the list. Twofifty.org has been useful to track what I’ve seen as well. But I have interests outside of the IMDb Top 250, and I need a way of tracking these.

I started a “to watch” Excel sheet. But there were three problems:

  1. I would forget what the movie was about
  2. I wouldn’t know what to watch next
  3. I’d have to manually delete movies I’d seen

So I wrote a program to do this automatically and create a Movie Wishlist. I just write the names of movies I want to see, and the program finds these movies on IMDb, gets their ratings and links them. It also goes through my “seen” movies and strikes out stuff I’ve seen.

So I can just click on the movie to see what it’s about. I can sort by rating or votes to decide what to see next. And I don’t have to manually strike out anything.

Take a look.

Classical Ilayaraja

This is the first of 15 articles titled Classical Ilayaraja appeared on Usenet in the 90s.
I’ve added links to the songs, so you can listen as you read.
You could also try my Tamil song search.

Recently, I watched the movie Chembaruthi on video. One of those unethical, “kuppai” screen printed video cassette, you know, that gives you a vision like that of a “soda-butti” watching TV without his spectacles! Ilayaraja has done a fantastic job in that movie. Though I had heared all those songs many times while I was in India, watching that movie created a reminiscent train of thoughts in my mind, about Ilayaraja, his music, the dramatic change he brought about in Thamizh cinema. I thought that it would be worthwhile to discuss his music, particularly the CLASSICAL aspect! I am aware that it is not possible to write about all his carnatic oriented songs, about how he has handled those raagas, how he has deviated from the classical style etc. But it would definitely be interesting to pour out our ideas once in a while in a random order of the raagas covered by him.

In Chembaruthi there are six songs, out of which 4 are carnatic based. All the songs were “sooper hits”. To a guy who knows carnatic music, the raagas are explicit, and to a non-classical rasika, they are just great tunes! This was one of his specialities, to give the raaga in almost good shape and also make a good cinema tune out of it. And of course, the rhythm should give scope for good dance movements so that the hero and heroine could share their love by dancing! Maybe, many of his tunes have to be branded as semi-classical or light music (even though the raaga form might be pure) only because of this rhythm factor.

Chalakku Chalakku Selai is one good number in Chakravaagam. There is no impurity in the tune (like any anniya swaram). He has confined to classical 16th, Sa Ri1 Ga3 Ma1 Pa Da2 Ni2 Sa. Of course, not to mention, that the lyrics are very bad, fighting to degrade the song from semi-classical to light music. In the charanam the heroine says kalyaaNam aagaama paay pOda vENaam, ennaala aagaadhu aamaam. You know, some good heroines with morality do say such deterrant, anti pre-marital sex things to the always advancing heroes!

Ilayaraja has only few Chakravaagams in his account. In the janya raagas of Chakravaagam, he has excellent numbers. Like, Malayamaarutham…. Sa Ri1 Ga3 Pa Da2 Ni2 Sa, Sa Ni2 Da2 Pa Ga3 Ri1 Sa. His first malayamarutham came as a pleasant surprise in Sridhar’s movie (for whom he always had a soft corner) Thenralae ennai thodu. I distinctly remember how the ‘Ananda Vikatan’ magazine wrote in glowing terms about kannmani nee vara kathirunthen song in Malayamaarutham. Yesudoss and Uma Ramanan had done a wonderful job in that song. Ga Pa Da Sa Ni Da Pa Da Pa Ga, Ga Pa Ga Sa Sa Ri. What a wonderful start! The sharp rishabam gave a beautiful colour to this song. Maybe Ilayaraja’s first Malayamaarutham was poojaikkaaga vaazhum in Kaadhal Oviyam. That was a good song too. Deepan Chakravarthi had struggled to keep in pace with that tune (like some violinists get into trouble with Seshagopalan’s pace!). Then came thenRal vandhu muthamittathu in Malayamaarutham in Oru Odai Nadhiyaagiradhu (another Sridhar’s movie). Gosh! That was a fast song too. Krishnachandar and S.P.Shailaja tried their best, but probably spoiled it. Particularly, S.P.Shailaja has sung like the shrill sound you hear when you apply the breaks on a car that you bought for $500! There are two other songs in which he has deleted both Ni and Ma in Chakravaagam. I don’t think that such a raaga exists in carnatic music with any known name. Those two songs are amudhE thamizhae (Kovil Pura), and nila kuyilae (Magudi). They are simply excellent. One should be an artist and play those songs to know their quality. amudhE thamizhae starts like Sa Ri Ga, Sa Ri Ga, Sa Ri Ga Pa Ga Ri Sa, Sa Ri Sa Da Sa… Pulamai Pithan’s lyrics glorified that song. In the charanam he says, if you listen to and speak Thamizh, oon mezhugai urugum, athil ulagam karainthu pogum, such is the beauty of this language! One cannot write any better, about the greatness of Thamizh language. (Those people like Thamizh Vendhan & co, who have no other job other than inundating the S.C.T with meaningless news about Thamizh Ezham, now, have a point!).

I vaguely remember a song “naan irrukka bayam etharkku” (Kuva Kuva Vaathukkal?) At that time, when I had primitive carnatic music knowledge, I had diagnosed that song as “Valaji” (Rishabam deleted in Malayamarutham, Sa Ga Pa Da Ni Sa, Sa Ni Da Pa Ga Sa, you can say that it is a janyam of Chakravaagam too, even though theorists might say ‘janyam of Harikambodi’). Maybe, that song is indeed Valaji. Ilayaraja has few songs in Revathi, another 16 Janyam. Perhaps the best onces are sangitha jaathi mullai (Kaadhal Oviyam) and kanavu onru thonruthe (Oru Odai Nadhiyaagiradhu). But I personally feel that MSV’s melodious use of Revathi is unparalleled in the song manthira punnagai (Manal Kayiru).

So much about Chakravaagam and its janyams and Ilayaraja. In Chembaruthi, two of the 4 carnatic songs, are in Sindhu Bhairavi raagam. They are kaadhalilE ezhumbura alaigaLai and “kadalile thanimaiyil”. Ilayaraja himself has sung the former (thso, thso rendition) and Nagoor Hanifa the latter. Both these songs are excellent Sindhu Bhairavi’s. One in three of all cinema songs are in Sindhu Bhairavi scale (one of the commonest cinema melodies, like the 20th mela Natabhairavi). Ilayaraja has innumerable songs in Sindhu Bhairavi, a variegated population from valai osai kalakala ena to shenbagame shenbagame etc. One cannot list all of them. But, probably MSV’s Unnakenna Mele Ninrai (Simla Special) is the best of Sindhu Bhairavi. In kaadhalilE ezhumbura the lyrics is unusually good. Probably, Muthulingam or whoever was the lyricist, had a strong tea before writing that song! That song goes to tell the pathetic life of fishermen. The lyrisict says in pallavi kadal thaneer karikudu kaaranam irukkudu, meenavar vidugira viyarvaikal kadalile kalakudu… (Sea water is saline because of fishermen’s sweat). Good idea, ain’t it?

Lastly,there is one song in Kaappi raaam in Chembaruthi: chembaruththi poovu (after decades, Banumathi Ramakrishna sang a tail piece of this song). His other Kaappi are ada maappiLLai (Siva), hei paadal onru (priya). As far as I know Ilayaraja is the only one who used Kaappi in cinema. All of them are good. He starts ada maappiLLai like, Ma Ga3 Ga3 Ma Pa, Pa Ma Ga3 Ma Ni2 Pa Ga2 Ri Sa Ni3 Sa Sa. Wonderful start! To start Kaappi in madhyamam and use its key phrase ‘Ga3 Ma Ni2 Pa Ga2 Ri Sa Ni3’ at the very beginning is an excellent approach to the tune. This is one of the instance in which his classical ‘vidwat’ was manifest. Even in chembaruthi poovu he uses the bashangam of Kaappi, in the very beginning, like, ‘Pa NI2 Ma Pa Ni3 Sa’. Why did he choose to score tune in Kaappi for both these above situations in which the bride and the groom are humoured by the ‘thozhan’ and ‘thozhiyar’ on the occasion of their betrothal. Is their any definite pattern that he follows in scoring tunes for situation? Maybe.

Return on effort

If you have a bunch of projects you could do, and want to decide which ones to take up, I was taught a rule: if a project has positive net present value, do it.

That is, find out how much money you have to put in (& when), and how much you’ll get out (& when). Adjust for money today being worth more than money tomorrow. If it makes a profit, just do it.

There are 3 aspects to this calculation, of which two are usually ignored.

  1. Time value of money. Money today is worth more than money tomorrow. People usually don’t adjust for this — either because they don’t know they should, or because they’re not sure how much to adjust by. It’s usually OK to ignore this. The difference is not often much. Your estimations of cash flow are likely to be off by more than this adjustment anyway.
  2. Cash flow projection. This is tough too. People batch these together into two groups: what you put in and what you get out.
  3. Investment and return. This is the often used part. You put in money (over time), and you get money out (over time). Do you get more than you put in? How much more?

In other words, I’ve seen Return on Investment (RoI) used far more than Net Present Value (NPV).

NPV vs ROI

In my MBA classes, I was taught that this is wrong. That you need to worry about RoI only if you’re budget-constrained. If you have enough money (and organisations can always borrow), you should do all profitable projects.

I can’t tell for sure if organisations are budget constrained or not. Departments do have budgets. But whether they stick to it or not depends on the department head’s risk aversion and political power. It often has nothing to do with projects.

But I’ve seen a bigger complaint cited more often: people don’t have time. Time is a bigger constraint than money.

This works in two ways. You don’t have staff to execute a more projects. Or you don’t have management time to pay attention to new projects.

If you’re constrained by money, it makes sense to maximise return on investment. But if you’re constrained by time, maximise return on effort.

BTW, effort is not the same as time. Outsourcing, for example, increases return on effort, but probably not return on investment. Vendors take money without taking up staff time (except a bit of management time). If you’re manpower constrained, and not money constrained, use them as much as possible. Similarly, investing in assets rather than in hiring improves return on effort.

When at BCG, there was a whole theme around this called Workonomics. Like Economics is about maximising return for money, Workonomics is about maximising return from your workforce. Powerful concept. It’s a pity I’ve never seen it applied where it’s really needed.

Economics vs Workonomics

The most important thing is: at any point, you have only one constraint. Maximise return on that constraint. If it’s money, maximise RoI. If it’s staff, maximise productivity. If it’s customers, maximise share of wallet. And so on.

You only eat plants

UTSUNOMIYA, Japan, Dec 1998. I was on a project with Honda R&D at Utsunomiya, Japan.

And I’m vegetarian.

The next day, Yoshioka-san — our counterpart at Honda — took us to the canteen and introduced me to the chef. Knowing that “vegetarian” in Japan includes eating fish and birds, I took the chef aside.

“I’m vegetarian,” I emphasised.

“Hai. Vegetarian.”

“I don’t eat fish.”

“Ah, so. No fish.”

“I don’t eat chicken. No birds.”

“Ah, so. No chicken.”

Pause. He looked puzzled. Just to be sure, I added, “I’m vegetarian.”

He thought for a long while, and then said,

“So, you eat only plants?”

P.S. I was finally served rice with brocolli. I ate it with pepper.
