I give a short summary of my trip to San Luis Potosi, Mexico. Over the past 20 years, several students from San Luis Potosi have completed our Ph.D. program at Notre Dame, and many of them have been in my classes. Of those, many are now on the faculty at their home institution, Universidad Autonoma San Luis Potosi. This week their electro-mechanical engineering department is celebrating its 50th birthday, and they invited me to participate in their festivities.
So, grateful that my colleagues Bill Goodwine, Sam Paolucci, and Mihir Sen agreed to teach some classes of mine at Notre Dame, I set out on my journey to the South on Wednesday afternoon, October 24. I took the South Shore train to Chicago and checked into the Silversmith Hotel in the Chicago Loop. Around 7, I met college chum Paul Link for a good dinner and conversation in the nearby Berghoff restaurant. I had the bratwurst and sauerkraut with potato salad, washed down by a Berghoff beer. We had a fine talk.
The following morning, Thursday 25 October, I got on the Blue Line CTA train and made my way to O'Hare Airport. There a fine breakfast of spinach omelette and hash browns was procured, and I got on the 9:15 American Airlines flight to Dallas. The Dallas airport is fancy and largely empty this day, with a very good internal train system and luxury shops abounding. Around 2:30, my American Eagle jet departed for San Luis Potosi. The fellow behind me turned out to be a physician who knew my cousin, Dr. Robert Toohill, of Milwaukee, Wisconsin. I was met at the San Luis Potosi airport by my former student and colleague, Dr. Antonio Cardenas, who is now the department chair. We had a snack at my hotel. Later, I joined Antonio and met some old Notre Dame contacts along with some new friends at the university's performing arts center, where we heard an address from a faculty from U. Washington who has used good science and engineering to start a large business in San Luis Potosi. He gave a fine talk. Pictured below is the atrium of the performing arts center.
I finished the evening with a snack at the hotel with Prof. Terry Chambers, of U. Louisiana-Lafayette who has had many interactions with the faculty here. He was the other external faculty invited by the department for the celebration. It turns out Terry is a good friend of my former graduate student Keith Gonthier, at LSU.
The following morning, Antonio picked up Terry and I, and we went to a lecture hall where we heard a good talk from a local leader. Below is the logo for the 50th party on display in the lecture hall.
Then we recessed to a classroom, where first Terry, then I, delivered our talks on our research to the graduate students and faculty of the program. After a meeting where the San Luis Potosi faculty discussed their own research, we recessed for lunch at a nearby Italian restaurant. Below are the lunchees.
Next, a former ND student Gilberto and his wife Irma gave Terry and I a tour of the town. San Luis Potosi is an old silver mining town founded back in the 1500s. The university was founded by the Jesuits in the 1600s, and its main building is pictured below.
The old city center is dotted with churches, plazas, and lovely Spanish colonial architecture. Below is a facade at the Church of el Carmen.
Here is a street vista in the city center, followed by a church and plaza.
Gilberto, Irma, Terry (all pictured below), and I had a nice enchilada supper with fancy artisan beer outside the Franciscan church and plaza.
Soon after, we returned to the hotel to prepare for an early morning trek to the famous pyramids of Teotihuacan, near Mexico City.
So, Saturday, we were met at 6:00 AM in the hotel lobby, and a group of seven of us piled into a university van for the four hour drive to the pyramid site. Our route was down El Camino Real, now a superhighway, but built on the path of the old royal road from Mexico City to Santa Fe, New Mexico. When living in Santa Fe, I was housed about 100 yards from the terminus of El Camino Real. We had some snacks and rest breaks along the way, and arrived late morning at the site. Below is a residential area for the old-timers.
Here is a kind of side alter, likely for things that didn't merit appeal to the facilities of the magnificent pyramid of the moon, which we climbed, or the pyramid of the sun, which we also climbed. As opposed to my other two visits here in the 1970s, you can no longer climb all the way to the top.
The pyramid of the sun, below, invites the sun, and so I repelled the sun with my trusty hat, which has also done duty at the China's Great Wall and Forbidden City. This was accompanied with Titanium-based sunblock all of which gave me a ghostly pallor.
We retreated to a nearby cabana where cervezas y pollo were procured topped off by cinnamon-spiced coffee at the end. Here is our crew.
The long ride back had some sleeping and lots of talk.
