Farewell, Ferney

Packing

When we returned from our Bulgaria trip, we spent 10 days sorting, discarding, and packing our belongings. How did we accumulate so much in 10 months?  Assorted books bought, some clothes purchased, several household items acquired at Ferney’s community-wide garage sale in September, a half dozen black stones laden with fossils picked up from flat dry land (remnants of a prehistoric sea) in Morocco during our Christmas vacation, two diminutive art pieces obtained at Lyon’s Sunday artisan market, miscellaneous French food items that are pricey in California… These acquisitions and others added to the mass of items we had brought to France: suitcases of clothes for 4 seasons for 3 people; books to read and tour guides to use on trips; our computers and cameras; art supplies; Spouse’s bike disassembled and packed in a secure, stout, durable black plastic bike box.  We ended up with 9 suitcases to take with us on the plane, 8 boxes and the bike crate to ship air freight, and 4 boxes of books to be sent through the post.

We made trip after trip to Spouse’s CERN office to store the suitcases and boxes because our apartment lease ended on June 30, and our tickets back were for July 6.  We stayed 5 nights in a hotel.

Our final day in the apartment was sunny, humid, and the hottest of the summer: 35 degrees Celsius, or 95 Fahrenheit.  With no air conditioning, working nonstop to finish packing by 6 PM, then cleaning the apartment, we were exhausted, sweaty, and tired.  But that evening we attended a community-wide festival, La Fête à Voltaire, held on the grounds of Voltaire’s chateau.  Blue, violet, and pink lights shined at different times on the chateau and church (which Voltaire had built).  Different civic organizations from the area sold food and drinks.  Not only could we buy traditional French fare, like crepes or champagne, but we also could purchase food from clubs of immigrants: Ethiopian, Moroccan, Haitian, Spanish, Russian, Tongan, West African and others.  On one stage a group of costumed folk dancers and musicians from Bourg-en-Bresse, the largest city in the département (province), performed and then taught dances to attendees of the festival.  And a community chorus of adults sang a cantata by Jean-Philippe Rameau (1683-1764), a contemporary of Voltaire.  In fact, Voltaire had written a libretto for one of Rameau’s operas, Samson, but it was never performed because Rameau feared that Voltaire’s criticism of the Church would create public discord.

Between “La Fête à Voltaire” on Saturday night – which seemed to be a suitable and sad adieu to Ferney - and our departure the following Friday, we dined with friends we had seen throughout the year and we toured places we hadn’t seen – a cheese factory in the Jura Mountains and a medieval town with an interesting religious history, both of which I’ll write about in the next few months.  

Cheese factory in the Jura Mountains

I drove around Ferney taking last-minute photos of scenes I wanted to remember, such as the statue of nude lovers which is located near the apartment where we lived, on a corner by the main road that connects Ferney-Voltaire to Meyrin, Switzerland.  We passed that statue at least twice a day when I drove Spouse to and from CERN.   Whenever I saw the sculpture, I assumed that Americans would ban from public display such a carving of a couple embracing in the buff, and I thought, “Vive la France!”

The day before we left France we took the boxes and bike crate to an air freight company at the Geneva Airport.

And then on July 6, the three of us, with our 9 suitcases and carry-on pieces, bid farewell to Ferney.

Although we didn’t spend an entire year in Ferney-Voltaire, we are fortunate for having had 10 months to live in France.  CERN Wife, however, will continue to write about French culture, which has been the subject of this blog.  But from now on, the blog posts will be written in Oakland, California.  France from not France.  Now that’s interesting.

Bulgaria - A Travelogue

Cart with flowers in Veliko Tarnovo

Bulgaria is one of those nations that needs a proactive Minister of Tourism to lure Americans and West Europeans (not just the usual visitors from Romania and Russia) into its historic cities and Black Sea resorts.   It’s a country that should be known for more than its yogurt, feta, the wrapper Christo, and the 1978 ricin poisoning in London of the Bulgarian dissident, Georgi Markov.   What most tourists of Greece and Rome don’t know is that Bulgaria was home to one of the most advanced prehistoric civilizations, the Thracians, who 6,000 years ago were the first culture to have created objects from gold, which can be seen in the Archeology Museum of Varna, a city on the Black Sea coast.  With its Roman and Greek ruins, Orthodox churches, mosques built during the 500-year Ottoman rule, summer heat, and outdoor restaurant culture, you’d think you were exploring a Mediterranean country.


Although there are only 7.3 million Bulgarians, they have an active physicist community at CERN most of whom are working on the CMS experiment.  One of these Bulgarian physicists, Leandar Litov, invited Spouse to give a series of lectures at a physics summer school he had organized at Primorsko, a Black Sea resort town.  We had met Leandar and his physicist wife, Nevena, in 2004 when Spouse was at CERN on sabbatical; our daughters were eleven-year-old classmates struggling to learn French together at the local collège (middle school).  We had decided then that we would like to visit Bulgaria, and just last month, from June 12-20, we had that opportunity.  We stayed four nights in Primorsko, and then embarked on an exhausting whirlwind 4-day tour of this curious ex-Communist country.

Plovdiv
From Sofia’s airport we rented a car and drove to Primorsko with a Bulgarian physicist from CERN named Alex, and on the way we stopped for a 3-hour lunch and quick tour of Bulgaria’s second largest city, Plovdiv, famous for its Roman ruins, cobblestone streets, and 19th century revivalist architecture, among other things.

Primorsko

The town of Primorsko is just like any beach town: shops selling hats, sunscreen, sunglasses, bathing suit wraps, and floating toys; bars and discos playing loud music late at night; outdoor restaurants; hotels, hotels, hotels.  In my wildest dreams, I never thought I’d ever have the opportunity to swim in the Black Sea, and for me, that was one of the most exciting activities of this trip.  Bathers could walk into the sea for what seemed to be a block or two, being lapped by gentle waves, with the warm and clear water still waist-high. Primorsko’s pristine beach is littered with sunbathers of all ages and sizes.  Men with nine-months-pregnant bellies strut as if they were flaunting seductive six-pack abs, and golden agers in their 70s and 80s are unabashed to lie topless on the sand nearby overweight middle-aged bleach blondes and young women with Barbie bodies.

Nessebar
The physics school held an afternoon’s excursion to the celebrated island-city of Nessebar, a UNESCO World Heritage Site.  Although prehistoric Thracian settlements existed on the island, Nessebar became known in the middle ages for its 40 churches, of which only a few remain, and none are used now for religious services.  A tour guide took us into one 10th century church, St. Stephen’s, and explained the iconography and rituals of the Bulgarian Orthodox church.  I took a few flash-less photos before we were told that no photos were permitted.

Varna

For archeology enthusiasts, Varna is a destination.  Its museum is renowned for exhibits of Thracian gold artifacts and stunning pottery.  But I had another destination in Varna, and that was to meet Mariya Koleva, a Bulgarian poet who writes in English, whom I had become acquainted with through an online writers’ group.  Mariya, her inventor husband Emil, and their endearing 3-year-old daughter, Silviya, met us Sunday morning at the hotel where Mariya gave me the first-ever printed version of her poetry ebook, “Sombre Chapbook” - with artwork by Emil.  They proposed being our tour guides, and escorted us to the Museum of Archeology, to the “petrified forest” of limestone columns, to Pliska, the first capital of Bulgaria from the 7th to 9th centuries, and finally, to Madara to see Bulgaria’s famous landmark hewed out of a high cliff – the Madara Horseman galloping over a lion, followed by a dog.  According to UNESCO (the Madara Horseman is also on UNESCO’s World Heritage List), this relief was carved approximately 710 AD.  Mariya, Emil and Silviya had made that day’s expedition from Varna to Madara impressive and unforgettable.  If only we could thank them by being their tour guides in the San Francisco Bay Area.

Veliko Tarnovo

From Madara we drove to Bulgaria’s San Francisco, Veliko Tarnovo, a city with a long history built on a series of hills that overlook the winding Yantra River.  Veliko Tarnovo was the capital of the Second Bulgarian Empire from the 12th to the 14th centuries, but we had no time to visit its old fortress city and other sites because we had plans to meet friends in Sofia.  So we spent just one night and morning in this charming city with so much to discover that our time there was barely an amuse-bouche.

Sofia



In the capital Sofia – a city teeming with traffic, dotted with parks, packed with communist-era concrete apartment buildings, and alive with new businesses and stylish twenty-first century housing – we visited three religious buildings: the huge medieval-looking St. Alexander Nevsky Cathedral, which was built between 1882-1912 (I had no idea that Alexander Nevsky was a real person; I associated the name with Prokofiev’s opera and Sergei Eisenstein’s film); the authentic medieval and diminutive 10th-century Boyana Church, embellished with extraordinary frescoes (another UNESCO World Heritage Site); and Europe’s third largest synagogue, which was completed in 1909.  Before World War II, Bulgaria had 50,000 Jews.  The Bulgarians, unlike other Europeans invaded by Hitler, saved almost all their Jews from extermination by the Nazis.

We had dinner (and breakfast before our flight back to Geneva) at our friends’ tree-shaded apartment in Sofia.  These friends - Nevena, Leander and Michaela - had kindled our interest in their country when we met them in France almost eight years ago.  They were responsible for our being in Bulgaria this year, and for suggesting which sites of their captivating country to see during our lightning tour.  Merci beaucoup!  

Leandar, however, wasn't at home the two days when we were in Sofia.  At the conclusion of his Primorsko physics summer school, he flew back to CERN for two weeks of meetings. Nevena, who is engaged in an interesting non-CERN physics research project about medical imaging, remained in Sofia.  I never told her, but I think that she is also a CERN Wife...

Higgs Boson


Enthusiastic physicists crowded the lecture hall, now an ersatz overflow assembly room.  The main auditorium had been packed by early morning with students and postdocs who had lined up before 5 AM on July 4 to procure a spot; other seats had been reserved for VIPs. They weren’t going to a rock concert.  Better than that, they were going to hear the results of two CERN experiments about the elusive Higgs boson.  

Overflow crowd in the lecture hall


Two non-physicist observers - CERN Wife and CERN Daughter - found seats by the wall in the lecture hall, and like everyone else in the room, sat facing a screen where two images from the main auditorium were posted: 1) a CERN logo noting "Higgs research update" and 2) views of the crowd in the main auditorium (where everyone in the overflow hall wanted to be).

Like the scientists in the room, we too were excited to witness the "Higgs research update" announcements from the CMS and ATLAS experiments.  Although we might not have grasped everything explained by the two spokespeople - Joe Incandela of CMS and Fabiola Gianotti of ATLAS - we knew that the results of finding either the Higgs boson or a Higgs boson-like particle were extraordinary contributions to scientific knowledge of the natural world.

The Higgs boson is the particle that is believed to be responsible for giving mass to other elementary particles.  It is the last unidentified piece of the Standard Model, which describes all of nature at a fundamental level, except for gravity and dark energy.  The Standard Model has withstood concerted attack by experimentalists, who for 40 years have been trying to find ways of disproving it.  But they couldn’t.  If this discovery turns out to be the Standard Model Higgs boson, the Standard Model will have been proven correct yet again.  If it turns out not to be the Standard Model Higgs boson, further questions about the natural world would arise, which for physicists is even more interesting.  At least, this is what Spouse has told me.

So there we were, listening to the two spokespeople's reports about some of the most expensive, exciting, and exhilarating experiments in recent physics history.  Although CERN Wife and CERN Daughter needed further clarification to understand the talks and the graphs, the crowd's contagious enthusiasm needed no explanation.

What, though, is a “boson” and why a “Higgs” boson?  A boson is a subatomic particle that has particular symmetries.  The name “boson” was coined by the theoretical physicist Paul Dirac to commemorate the contributions of the Indian mathematical physicist, Satyendra Nath Bose (1894-1974).  “Higgs” refers to the English theoretical physicist, Peter Higgs, who hypothesized the existence of this boson in 1964.  Although 5 other physicists (Robert Brout and François Englert from Belgium, and the Americans Gerald Guralnik and C.R. Hagen with Tom Kibble from England) wrote papers on the same topic at the same time as Higgs, the boson responsible for mass is named after Higgs.  Was that because his name is the easiest to pronounce?

And then there is the connotation of the Higgs boson being called the “God particle”.  This epithet comes from a popular book published in 1993 by physicist Leon Lederman and science writer Dick Teresi: The God Particle: If the Universe is the Answer, What Is the Question? Lederman wrote that the Higgs boson is key to understanding the structure of matter but is elusive.  However, he originally wanted to call it the “Goddamn Particle” because of its “villainous nature” - but the publisher wouldn’t let them use that term.


When Spouse had forwarded me the CERN press release several weeks ago about the July 4 seminar to update the scientific community regarding the Higgs boson search, I knew that I wanted to be at that colloquium, even if I needed to take Physics 101 again.  This was going to be a momentous announcement, and as an anthropologist, I wanted to be part of that audience and experience their exhilaration.  But I’m still a little unclear about term “boson.”  I agree with my cousin Nancy (a professor at Stanford University): considering how physicists name things like hard probes and hot quarks, wouldn’t a Higgs bosom make more sense?
