I would like to thank all those that contributed to the Turing Centennial series: all those who wrote posts, for sure; but also all those who spread the word about this, on blogs, twitter, facebook, and in real life; those who came to read them; and those who wrote lots of thoughtful comments. In a community where discussions over conference organizational issues or over the importance of matrix multiplication algorithms can become very acrimonious, I am impressed that we could have such a pleasant and troll-free conversation. This goes to show that in theory has not only the smartest and most handsome readers of the whole internet, as was well known, but also the nicest ones!

We will definitely do this again in 2054, to mark the centennial of Turing’s death.

A few days ago, I was very saddened to hear of the death of Sally Ride. A Stanford Alumna, Sally Ride became to first American woman to travel in space, she served on both the investigative committees after the two Shuttle disasters, and dedicated the past decade to the goal of getting young kids, and girls in particular, interested in science and technology. She cofounded, and directed, a non-profit foundation to further these goals, and wrote several books. After her death, it was revealed that she had been in a 25-year relationship with another woman, who was also the coauthor of her books and a partner in her foundation.

I think it is significant that a person that certainly had a lot of courage, determination, willingness to defy stereotypes, and to be an inspiration for people like her, felt that she could not be publicly out during her life. (In interviews about their books, Ride and her partner Tam O’Shaughnessy referred to each other as “friends”.)

Let’s hope that in 2054 it’s not just computer science professors in the West that are confortable being out, but also astronauts, movie stars, professional athletes, and so on.

[Leaving the best for last, here is Ashwin Nayak's post. Unlike the other posts in this series, Ashwin does not just talk about events, but he also gives us a view of his inner life at several critical times. What can I say to introduce such a beautiful essay? I got this: congratulations Ashwin! -- L.T.]

(Some names have been changed to protect privacy. Some events have been presented out of chronological order, to maintain continuity in the narrative. The unnamed friends in Waterloo are Kimia, Andrew, Anna-Marie, and Carl. I would like to thank them, Joe, Luca, and especially Harry for their feedback on a draft of this blog post. Harry offered meticulous comments, setting aside a myriad commitments. Most of all, I would like to thank my sisters and my parents for graciously agreeing to being included in this story.

For those not in theoretical computer science, FOCS is one of the flagship conferences on this subject. Luca is a professor of computer science at Stanford University, and Irit at Weizmann Institute of Science.

A prelude: I was born into a middle-class family from the South-West coast of India. I am the youngest of three siblings, and grew up in cities all over the country. My father served as an officer in the Indian army, and my mother taught in middle school until she switched to maintaining the household full-time. I went to IIT Kanpur for my undergraduate studies when I was 17. At 21, I moved half-way across the world to Berkeley, CA, for graduate studies. In 2002, after a few years of post-doctoral work in the US, I moved to Waterloo, ON, to take up a university faculty position.)

We were walking through art galleries in San Francisco when Luca brought up the Turing centenary events that were taking place around the world. None of the events celebrating his work referred to Turing’s homosexuality. Luca wondered whether the celebrations would be complete without revisiting this aspect of his life. As a response, he was thinking of having a series of guest blog posts by contemporary gay and lesbian computer scientists about their experiences as gay professionals. How would they compare with those in Turing’s times?

I wonder how much of my attention was on the art in the next few galleries. Would I write a post? What would I write? For me, sexuality is so deeply personal a matter that I’ve talked about it only with a handful of people. Why would I write about it publicly? Something Luca had said stuck in my mind: “The post could even be anonymous. That would be a statement in itself.” It took me back to my first relationship: I dated Mark for over three years and no one other than his friends knew. Times when I was on the verge of telling a friend about my relationships flashed by. I remembered the time I discussed with my immediate family why I would not get married (at least not the way they imagined). Times when students recognized me at events for gays and lesbians resurfaced, as did conversations with friends and colleagues grappling with openness. I would write a post, I told Luca.

That night, I got little sleep. Memories that I thought had slipped into oblivion loomed large. Read the rest of this entry »

[Martin Farach-Colton is a professor at Rutgers, in the gayest computer science department in the country. He is well known for his work on algorithms and data structures. In the Fall of 1998, I was a post-doc at DIMACS and I lived in New York; since we had the same commute, I would sometimes get a ride from Martin. I was still quite new to the US, and I remember thinking it strange that Martin was the only person driving normally, while everybody else was going so slowly. Martin is the dean of out theoreticians, and he has written a very interesting post. I wish he hadn't given up so easily on the theme of sexism vs. homophobia. -- L.T.]

When Luca asked me to write a guest blog post on “Putting the Gay Back in the Turing Centennial”, I was happy to say yes. But I had a problem. If I were to write about being gay in the theory community, what could I write about? I’ve always been quite comfortable being openly gay in the theory community, and that doesn’t make for a very interesting story, does it?

But first, some context: I grew up in South Carolina, in an Argentine family. Both my family and my surroundings were deeply homophobic. When I moved away from home to go to medical school, I found myself in yet another very homophobic environment. Nonetheless, in 1986, I decided it was time to meet Mr. Right, and the first step was to come out to all my friends and family. Within 6 months I was living with Andrew. We’ll be celebrating 26 years together in a few months, as well as 9 years of marriage. Our twins are 12.

I wasn’t fully out at medical school, but when I started my PhD in Computer Science, I threw open the closet doors and was totally out from Day One. It would be years before I met another openly gay or lesbian computer scientist, and even more years before I knew of another LGBT theoretician. Yet I have found that being gay was no big deal within the theory community. Practically no one seems to care, and that’s the best kind of acceptance there is.

Remarkably, I felt this kind of open atmosphere at the very first FOCS I attended back in 1989. The world has changed a lot for gay people in the last 23 years, but the theory community changed earlier. Sure, people have said some homophobic things to me, but these were almost all minor incidents, and I’m also sure that those people would now be mortified by what they said 20 years ago. More often than not, when gay issues come up with my theory colleagues, they are mostly interested in topics like a technical analysis of how the fight for marriage equality is going. (I’ve been involved in this fight both here in the US — where there’s still plenty of work to be done — and in Argentina, which now has the most progressive LGBT laws in the world.)

What can explain the culture of the theory community? I turned to some of the women of my academic generation to see what it’s been like for them. After all, it seems that homophobia and sexism go hand in hand. Right off the bat, one of them torpedoed my premise. She pointed out that there have been plenty of gay men who are acknowledged as great geniuses. There is no stereotype to overcome with respect to being gay and being good at math. Indeed, in addition to Turing, Hardy was famously gay, as were Komogorov and his partner, the topologist Pavel Alexandrov. I’m not placing myself in such exalted company but merely pointing out that perhaps I had it easier than women in the field because I had fewer stereotypes to overcome.

I found general consensus that, although the theory community is not free of prejudice and stereotype, it’s a comfortable place for a lot of people. Perhaps it’s not just theory. My own department had, at its high-water mark, four openly gay faculty, two of whom were recruited as a couple. I also found Google very gay-friendly when I worked there in the early ’00s.

So, really, I feel like I have nothing substantive to say on the subject. And maybe the best news. To paraphrase Tolstoy, happiness is dull.

Two more posts are coming soon. Meanwhile, here is a wonderful interview with Robert MacPherson, which is part of an interview series by the Simons Foundation. Although the interview does not mention Turing, it does mention Kolmogorov.

(via Not Even Wrong)

From this New York Times article:

Researchers found the home test accurate 99.98 percent of the time for people who do not have the virus. By comparison, they found it to be accurate 92 percent of the time in detecting people who do. [...]

So, while only about one person in 5,000 would get a false negative test, about one person in 12 could get a false positive.

It is late Spring in 2000, and I am to have lunch in New York with Ran Canetti and Ronitt Rubinfeld. Ronitt is already there, and Ran arrives a bit late and asks what we are talking about. “I told Ronitt that I am gay” I say. “Oh…” says Ran “Congratulations!
