on religion

Last night I went out to meet some friends, and there was this dude who was complaining about how expensive tickets are to the east coast. It turns out that unfortunately he would need to fly out on 1-2 days notice for his grandmother in-laws funeral soon. And as he explains his wife was very close to her grandma, so she really wants to go to her funeral.

This is absolutely mind boggling for me, because first of all, we are talking about 1 day and possibily $1000. But naturally I wonder why he doesn’t want to fly out now to say proper the goodbye. The answer I got was that he doesn’t have the vacation, and that his grandma may have the entire month to live. It blows my mind completely. You can’t take the time to say a proper goodbye when that person is alive, but yet you care about someone so much that you HAVE to attend their funeral, AFTER that person has passed away? Isn’t it backward?

Apperantly it is his religious practice that you want to show God the you respect the person after they passed away, and that according to him, is more important than showing ther person that you care when he is alive. I am not in any position to question any religious believe. People I am close friends with like Tracy and Ronnie are very religious person too. They would allow religion to influence their value system, but never to a point so ignorant that you blindly follow what the book say. I would expect someone with a college education to have the basic intelligent to pick the religious practice that make sense.

Caring someone ONLY after they passed away, is clearly not in my book.

technical specs

I am currently reading this book called Brunelleschi’s Dome. The book is a story about the construction of the dome in the cathedral commonly known as Duomo in Florence. The more I read it, the more I was amazed by the ingenuity that people came up with to achieved what seemingly difficult even today, given the simple and premative tools they have back then. Brunelleschi was what we’d call today the structural engineer of the project. With the official job title as the master carpenter, he is responsible for overseeing the construction of the project.

Being a geek that I am, let me explain the problem space. The dome has a pointed semicircular shape (think of a really stift breast) that’s made of 8 different panels. To get a taller dome, the curvature of each panel is more gentle than such at the circumference of the base. The center of curvature therefore are 8 different point away from the center of the dome and slightly below the base of the dome. First he surveyed the center of the dome which spans 70 feet with just a couple of ropes and a lead weight. From that, he marked the position of every brick and constructured the base of the dome. Up till this day, no one clearly knows how he managed to find the center of curvature for each of the panels on an imaginery base with the tools that he has. It is assumed that with that a support extending the 130 feet radius of this imaginery circle is built. And as the support rotates, it serves as a guide for each and every brick in the panel. And all has to be done with the accuracy that they will meet at the top at the same point. An inch of error on the measurement of the center of curvature, or the length of the support would be magnified to more than 6 inches at the point where the six panels are supposed to meet.

So that gave him a nice little problem to work with. And on top of that he is in charge of a crew of 100 stone masons, who are mostly illiterate at that time, who works on a daily pay schedule. Imagine the detail that his specification needs to get to. He has to go the length to allocate a 1/2 sq miles space so he can have life size sketches and guides everyday of the brick layouts so his stone masons can follow. This just amazes me the attention to detail one has to go through.

Compared to the technical specs that I produce for my projects, it’s nights and days of a difference. It is true in general that the more you learn about a subject, the more you appreciate its complexity. Things like the dedicated power filter for an audio amplifier, the temperature regulator on Vivace’s coffee grinder, the sharp edge on the tourneau curve on the Omega Retrograde; all are results of people who pays great attention to detail to achieve near perfection in the work that they do.
