The absence of darkness is light

My current read is a novel I borrowed from the local library called The Rule Of Four, written by Ian Caldwell and Dustin Thomason. It has been three weeks since I first took it out and I still have not finished reading it. I am perhaps two-thirds done... pretty slow by normal standards but I want to complete it nonetheless.

It is a story about two university students trying to unravel the mystery contained within the pages of a book written by an Italian during the Renaissance period. Quite heavy going sometimes.

Anyway it is not my intention to do a book review. I just would like to share a passage from the book which I found quite enlightening. I was afraid if I wait until I finish reading the whole book, I might forget where the passage is. In this paragraph, the narrator is musing about his room-mate and fellow researcher...

The fact is, Paul has always kept secrets from us. For years he hid the truth about his childhood, the details of his parochial school nightmare. Now he's been hiding the truth about his relationship with Taft. Close as he and I are, there's a certain distance now, a feeling that while we have a lot in common, good fences still make good neighbours. Leonardo wrote that a painter should begin every canvas with a wash of black, because all things in nature are dark except where exposed by the light. Most painters do the opposite, starting with a whitewash and adding the shadows last. But Paul, who knows Leonardo so well you'd think the old man slept in our bottom bunk, understands the value of starting with shadows. The only things people can ever know about you are the ones you let them see.

The Leonardo mentioned above, is of course, Leonardo da Vinci, the genius artist, inventor, mathematician, engineer and everything else. The last sentence in that passage is the one I really like.

I guess I am like that... I don't reveal too much of myself. The surface me does not tell too much of the inner me. Even close friends or family members have different bits and pieces of who I am. If they are to gather around and share information, some of them would probably say, `Hey, I didn't know that about him.'

The only things people can ever know about you are the ones you let them see...

Early withdrawal will lose interest

I think I'll write about an interest subject today... yes, that's right, an `interest' rather than `interesting' subject. Although I do hope the post may turn out interesting for readers in the end.

But first, I have to go back in time a little bit. It was the winter of 1983 and I was in the final year of my engineering degree. One of the toughest subjects in that degree course is Structural Mechanics, not one of my stronger suits. The professor who taught us that subject is Dr. Neil Taylor, a brilliant and aggressive man who's quite unlike any of the other lecturers in our faculty.

Dr. Taylor is slim and tall, sports long hair to his shoulders and keeps a beard and moustache. He normally wears a white shirt with a narrow tie but with collar unbuttoned. Over this he dons a black leather jacket. In fact, he looks more like a rock star than a university professor. His classes are never boring. He speaks in a loud, clear voice and at great speed. You'll never fall asleep during his lecture... or perhaps you dare not fall asleep. He'll pick a bored face among his students in a second and start shooting questions about the subject at hand, just to make sure we all understand what he's talking about. I was always afraid to be caught by him because, as I said, I'm not terribly good at Structures.

He would start his lecture by first talking at length about a particular topic. After that, he would scribble out his notes, longhand, on the blackboard. His notes are copious and he writes like he speaks... at great speed. When he runs out of writing space on the blackboard, he returns back to the earlier section and starts rubbing them out. Sometimes, those of us slow writers would need to hold out our hand and shout, `Whoa! Sir..', and he pauses for a while to give us time to catch up.

It is during such pauses that Dr. Taylor would usually tell a story or share bits of trivia that has got nothing to do with engineering. It can be something about music, movies, sports or current affairs... practically anything. And such interesting stories too... which sort of put the slow-writing students in a dilemma. Do you stop writing to listen to the stories and risk not copying down the complete notes... or do you continue to scribble furiously before he starts cleaning the blackboard and you miss the story being told?

I liked listening to his stories so I trained myself to be speed-writer.

One day, after filling the blackboard with his sprawling handwriting, he paused for a while to allow us some time to finish copying... and then starts to share another trivia.

`Do you know why most of the big time bankers are Jews?' he asks. None of us answer... so he begins telling the story about Christians being forbidden to be involved in usury and that the Jews may not charge usury among their own kind but can do so to others. He said that money-lending first started out as one of the least respected professions and strangely enough today, it is the money-lenders who control most of the world's economy.

`I bet you didn't know that, did you?' he mocks us. `Heck, does anybody even know what usury means?!'

`Yeah,' I immediately quipped. `Interest...'

`Who said that?' Dr Taylor looks around at his students, his eyes wide in disbelief. I sheepishly put up my hand halfway.

`Right, you are!' he said. And with that, he turned around, erased the blackboard and resumed writing his notes.

When the class was over, Dr. Taylor heads out of the room but when he reaches the door, he turns back and walks to where I was sitting. He bends down to my eye level and nodded to me to say, `Usury... that's good.'

From then on, I could no longer remain low-profile in Dr. Taylor's class. But the good thing was that my grades in Structures improved...

Nature at home...

I was doing a spot of gardening earlier today and came across a reptile and an amphibian enjoying their day among the leaves of my plants.

Look before you leap

Today is a special day. It is the first time I am able to put up a post in this blog on a day that comes once in every four years. February 29, 2012.

We all know what a leap year is... but why does it have 366 days instead of the 365 that we get from a normal year? Nowadays, it is very easy to get an answer to this question... just google. But back when I was in primary school, I remember looking for the answer in a thick book in the school library.

It was 1972 and I was in Standard 4. My teacher told me that the month of February in that year has 29 days. When I asked why, she told me to look for the answer in a book that explains about our solar system. I remember looking at an illustration in the book showing the Earth with an imaginary line circling the Sun. The caption below the picture says that the time it takes for Earth to do one complete revolution around the Sun is 365 and 1/4 days. This then equals one year. But then, it would be impractical to have a quarter day at the end of each year... just imagine that there would be a December 32nd that lasts for only 6 hours, from midnight to 6am, and that New Year's Day (1st January) would then start at 6am. Everything would be out of sync.

It was Julius Ceasar who first introduced the concept of leap days when he invented his Julian calendar at around 45 BCE. It was not terribly accurate and was later improved by a new calendar created by Pope Gregory XIII around 1,500 years later. The Gregorian calendar now forms the basis of time tracking and measurement for most of the modern world today. But why do we need to add that extra day every four years? It is because of the seasons. If we don't add the extra day, we lose about 6 hours every year and winter in the northern hemisphere would start to move forward. The recoupment of that 6 hours each year for 4 years ensures that the seasons happen at roughly the same time every year.

While refreshing my knowledge on this subject earlier today, I found out that the Earth's orbit is not exactly 365 and a quarter days. It is approximately 365 days, 5 hours, 48 minutes and 46 seconds... and I say approximately because this duration can vary slightly depending on the relative position and influence of other planets. This means that even adding a day after every four years is not really that perfect if we look at the big picture. But the effect may only be significant in 8,000 years time. That's way ahead in the future for us to worry about... let the people living at that time solve it themselves.

Two weddings and a sunset

It was a packed day today. The first wedding was at Rengit in Batu Pahat while the second one was at Muar. After the second wedding, I headed out to Masjid Sultan Ibrahim by the south bank of Sungai Muar. I had hoped to catch some good sunset pics at Tanjung Emas near the river mouth but unfortunately the clouds were dark and overcast.
