Sometimes intersection points come to my hometown!!

Remember how one evening, while spending a few idle hours with my inlaws in our backyard, I realized that Bidisha is a relative of mine? Bidisha being the person that we got to know regarding a nanny and while my family has met her, I have never met her. Of course, since she is my new found relative, I had figured that I would meet her next time I was in Dallas.

Last night, after 1:30 am (I am sure too much drinking was involved 🙂 ) I got a message from Amitesh that her husband was in our town. He (Amitesh) was able to get the three of us together for lunch on my way to the airport.

That was a great hour. He is a SMU professor. Most of the discussions were around the fallacy of prediction methods – from biases in selecting independent variables to faulty assumptions in correlation methods to the almost impossible problem of finding discontinuous functions mathematically (unfortunately, real life does not work in a smooth curve). It was a very intellectually stimulating discussion. The yellow curry at Thai Spice was not bad either!!

Now I have two more books to read, thanks to Neil Bhattacharya!!

Another random shot from last evening : Southwest plumes

From the colors, this is a Southwest plane. Here is funny part. Southwest does not fly this equipment out of Atlanta. They fly the equipment from their purchased airline company AirTran. So the nearest airport that this plane could have taken off from is Birmingham, AL. Which would mean it was at least 25,000 feet high if not already in its cruising altitude of 30,000+. Very good clarity for a 300 mm lens. The absolutely clear sky helped a lot. The naked eye would have had difficulty locating the plane if not for the plumes and the sound.

Speaking of the plumes, it is interesting how they seem to originate from the tail. In reality, it is the water vapor coming out of the two engines under the wings condensing and most likely crystallizing immediately in those sub zero temperatures. The microsecond time gap of the colorless vapor crystallizing to white ice particles (white because of the air trapped in them) is just enough to create the illusion that it is the tail that is generating the long plumes!!

Wish every weekend evening was like this..

Another hectic week. Another weekend. If I had my way, every weekend would be like this. Sitting outside with all the necessary ingredients – Sharmila, her parents, Pinot Noir, the citronella lamps, the camera and iPhone to capture the moments and songs from the iPhone. As you can see from the last picture , everybody listened to songs well into the night….
