That was the headline I saw on the front page of a newspaper on Sunday, part of the build-up to the five year anniversary of 9/11. Reading the article, I realized that I don’t know what it means to be ‘safe’, as in the thing we are still not. Does it mean zero risk? If so, we have never been and never will be safe. Does it mean we still don’t ‘feel’ safe? That’s an interesting question for a therapist, but given the irrationality of most people’s fears I don’t think it has a whole lot to do with actually being safe. So what does it mean to be safe, and in particular safe from terrorism?

I thought about this question a lot a couple of years ago when I was traveling frequently to Israel. People would ask me if it was ‘safe’ to go there, given the suicide bombings and such. My response was always the same: have you ever seen the way Israelis drive? The probability of dying in a car accident over there is far, far greater than the chance of being the victim of a terrorist. Interestingly, that would almost always calm my worried friends down. It seems that traffic deaths are, well, too pedestrian to get all worked up about.

So let’s try out the same tactic on America. In the last five years about 3,000 Americans were killed by terrorists. And if you believe our President, the chances of another terrorist attack like 9/11 are lower today than five years ago. Now during that same five year period, over 200,000 Americans died in car accidents. A simple analysis of these statistics shows that the average American is about 100 times more likely to die in a car accident than a terrorist attack.

So are we safe? No, but terrorism is way down on the list of things we are not safe from. If saving American lives was the real issue, we’d be focusing on car safety rather than car bombs. But the anti-terrorism campaign has never been about saving American lives. It’s about trying to eliminate one class of US fatality – death by terrorist. I guess it really is about feeling safe rather than being safe after all.

Those who can’t do, teach. I’ve never liked that old saying, mostly because I like to teach (and flatter myself that I’m pretty good at it). I’m teaching now at Notre Dame, but am also immersed in finishing my textbook, Fundamental Principles of Optical Lithography. I guess a corollary to that old saying might be “those who can’t do, write.” I guess I don’t like that saying much either, but a slightly changed version is most certainly true: “Those who write can’t do.” I can attest to the truth of this statement for one simple reason – writing a book is all consuming. If you really pour yourself into writing, you just don’t have anything much left over to do anything. At least that is the way it is for me. I hope to be finished by the end of the year (already 5 months past my deadline!), so until then I doubt I will get much done, including all the interesting articles I am planning for my web page. Ah well.

BTW, for all the lithographers out there who are reading this, what do you want most out of a lithography textbook? Give me a shout.

I am slowly settling in the South Bend, Indiana – classes at Notre Dame start on Tuesday. While driving up with my dog (my wife and daughter flew up a few days later), I learned a few lessons about cross-country trips – something I hadn’t done since my college days.
* Cell phone coverage in Arkansas sucks – avoid long phone calls while driving there
* The price of gas in Illinois is 5% higher than in neighboring states (why?)
* Never name your dog anything that rhymes with “no” (a lesson taught to me by my friend in Pana, Ill whose disobedient dog is named Mo)
* The only place in America where you can’t get a Starbucks coffee is Pana, Illinois
* Lowell, Indiana is a very beautiful little town
* Even an old guy like me can do a long road trip – provided he has a comfortable seat, cruise control, and a long audio book (thanks, William)

Here are a couple of cool site that I have enjoyed for a while or just discovered.

When I was in college, my favorite reading was the Journal of Improbable Research. While this magazine went through several iterations, editors and sponsors, it is now called the Annals of Improbable Research (AIR). While the journal is not on-line, they do have a website with some really interesting stuff, including information on the Ig Nobel prize. www.improbable.com.

One of my regular blog readers sent me this (I guess I’m assuming that I have more than one regular reader, though I have no proof). It’s a site dedicated to the mid-seventeenth century Jesuit polymath named Athanasius Kircher, a guy who studied everything and wrote down everything he learned in massive encyclopedic works. His life’s work was “chronology”, creating a complete list of human events throughout the entire history of the world. The current blog on their site describes the world’s longest running experiments. Cool stuff. www.kirchersociety.org/blog.

Today is Belgian Independence Day, and I stand and toast my friends in Belgium, inventors of French Fries and fruit beer, with a glass of Chimay White in my hands. Cheers! Salut! Proost!

Like most Americans, I am woefully ignorant of any independence day other than my own country’s. So after some quick internet research, here’s the story behind the birth of Belgium. After the defeat of Napoleon in 1815, Europe was carved up by the victors with the goal of containing French imperialistic ambitions. What is now Belgium was given to the Netherlands. The French-speaking Catholic population chafed under the rule of the Dutch-speaking protestant king, and simmering tensions came to a boil in the Brussels Opera Riot of August 25, 1830. I’ve never seen an opera that made me want to riot (at least not outside of the theater), but apparently this particularly jingoistic performance excited its crowd to such a point that they left the theater shouting patriotic slogans and quickly took over several government buildings. The Dutch sent in the troops but after several bloody days of fighting in the streets of Brussels were unable to route the revolutionaries. The provisional government declared independence on October 4.

So independence day in Belgium is October 4, right? Well, sort of. The new Belgian government needed a king (don’t all European countries need a king?), and offered the job to one Leopold I, a typical European royal of the day: son of a German duke and a Russian countess, general in the Russian army fighting against Napoleon, etc. Leopold had just turned down an offer to be king of Greece the year before, but apparently the climate or the benefits (or maybe the beer) was better in Belgium. He ascended the throne on July 21, 1831. (Two weeks later the Dutch invaded again in an attempt to regain their runaway province. The French army came to the support of the new Belgians and the Dutch went back home after ten days, averting what could have been the shortest royal reign in history.)

So there are two Belgian independence days. Or one independence day and one national day. Or something like that – I’m not really sure. In any case, it is a good day to drink a fine Belgian beer, and there are many to choose from. And on October the 4th, I’ll do it again. The sacrifices one must make in the name of international solidarity…

It is Wednesday night, so I must be feeling fine. The certainty with which I can predict this mood comes from the regularity of my Wednesday afternoons: from 4 – 6pm each Wednesday I attend an important Symposium.

The word ‘symposium’ comes from the Greek symposion, “a convivial gathering of the educated” and the Latin symposium, “a drinking party”. It’s meaning comes mostly from the title of one of Plato’s dialogs, where a bunch of guys without anything better to do sit around and drink while talking philosophically.

I’ve attended a lot of symposia over the years, including the SPIE Microlithography Symposium for the last 22 years. Most of these meetings have forgotten the true essence of what a symposium means (though I have been know to wax philosophic at some of the hospitality suites at the Microlithography Symposium over the years). My regular Wednesday commitment, however, remains true to it’s Greco-Roman symposia roots. About five to ten people meet at one of my favorite Austin pubs, drink beer, and with no set agenda have fascinating and valuable conversations. The perfect combination of taste bud and brain stimulation. What could be better?

So if you want to catch me in a good mood, get in touch with me on Wednesday night. But if you want to see me on Wednesday afternoon, you had better be attending the Symposium – otherwise you’ll miss me.

My wife’s grandfather just emailed me this joke:

Two missionaries are looking down into jungle clearing at hundreds of natives gathered around a stone likeness of a huge zero.

They strain to hear what they’re all chanting, but finally make it out: “Nulll, nulll, nulll…”.

“My God!” one says quietly to the other. “Is nothing sacred?”

This is cool on many levels. First, I get emails from my 85 year-old grandfather in-law (my dad refuses to even read an email on the screen if you get it up there for him, let alone use the computer to send an email). Second, the emails he sends are most often geek-humor. Granted, he is a chemical engineer so he has earned his right to relate to Dilbert. But it just goes to show you that even if you think the hyper-fast paced internet-fueled information explosion is changing all the rules, some things about human nature remain the same: there are nerds among us, and we like nerd-jokes. There’s comfort in continuity.

An update on what’s going on with me: I have recently accepted a position as the Melchor Visiting Chair Professor at the University of Notre Dame for the Fall 2006 semester. It is a one semester appointment with the electrical engineering department, where I will teach two classes: Semiconductor Microlithography and Data Analysis and Modeling. I love to teach, and Notre Dame is great school, so it should be fun. Besides, they threw in football season tickets. Hard to beat that deal, eh? And besides, if my wife still loves me after 4 months in South Bend, Indiana, we’ll know that our marriage is secure.
