Prayag

Sunday, August 23rd, 2009

The Harish-Chandra Research Institute is located on the banks of the Ganga, within sight of where the Yamuna flows into it. From its magnificent gardens you can see the sand bank that marks the confluence of the two most sacred rivers of Hinduism. Everyone-mythical figures such as Rama and Krishna, poets such as Kalidasa and Gurus like Vivekananda- has been at the Sangam. Today I got to see it up close. After a trip to the city of Prayag that has existed at this point a few thousand years.

Allahabad, as it is now known, is a small city but with an exceptional influence on India’s history. Half of its Prime Ministers are from here. Of course, three of them are lineal descendants of Nehru, whose house here we visited today.

This is in the heartland of India. And people here are large hearted. If you can avoid the moneygrabbing priests at the makeshift temples, everyone is laid back and seem generally happy. A few dollars go a long way. We saw no tourists, unlike at Varanasi. This ancient land exerts a pull, a yearning to reconnect with the past that is not rational and all the stronger for it.

My Name Is Khan

Sunday, August 16th, 2009

Shah Rukh Khan, the hero of many Bollywood movies, was detained by US immigration for two hours because his surname popped up on a watch list. Khan is the most common last name among South Asian Muslims; there are more Khans in the world than Smiths. Even in the US, it is the 665th most popular name.

Khan was an honorific title of Mongol tribes, and eventually was adopted as a surname by many people who are descended from a Khan or wanted to be associated to the name. Indeed, 0.5% of all men in the world carry a genetic marker believed to be passed on by Genghis Khan. There were strong selective pressures to help propagate the Khan name when the Mongols dominated the whole of Asia.

One among the hundreds of millions of people with the surname Khan is a very bad guy: AQ Khan, the man who built the Pakistani atom bomb and sold nuclear secrets to Libya and North Korea. But the surname alone has very little value in identifying a person in this case: US immigration should have known how common it is.

On the other hand, Indians tend to be overly sensitive in such matters. Only a month ago there was a furor because Indian employees of Continental Airlines frisked former President Kalam. This was considered an indignity: all Indian airports post a list of VVIPs (Very Very Important Persons) who are exempt from security procedures, a list that starts with the President and former Presidents. Indian culture accepts such special treatment for celebrities and retired politicians. (more…)

The Entrance Exam Frenzy

Wednesday, August 12th, 2009

Here in Kerala, the teenagers are the busiest people. They start their day at 7:00 in the morning with classes to prepare them for the brutal competition in the entrance examinations to publicly run colleges. 9:30 to 3:30 is school. Then its off to classes again. Often till 9 pm. Weekends are even busier. Classes the whole day. Then homework.

Mechanics In One Dimension

Friday, August 7th, 2009

Finally I post something about physics. Here are notes from lectures on mechanics to freshmen at the IISER-TVM. I didn’t have time to edit it. Any corrections ( spelling mistakes, algebraic errors etc.) are welcome. It usually takes me a few iterations to get everything right.
