Yongsheng Gao was born in Jinan, the capital of the Shandong province of China, also the home of Confucius some 2500 years ago. The Yellow River flows by Jinan, the ‘City of the Springs’, with the Mountain Tai nearby.

Unlike most of us at CERN, Hans Peter Beck is a Swiss native. He grew up in places like Weggis, on the shore of Lake Lucerne; Wolfenschiessen, in the mountainous interior of Switzerland; Dietikon, a suburb of Zürich, and finally in Zürich itself. He completed his matura – the Swiss secondary education – at the Mathematical Natural Science Gymnasium, Rämibühl, Zürich. Although he received better marks in chemistry at the time, physics held a much stronger attraction because it delves into matter at its most basic.

Looking back, as he can now, from a position of maturity, Nabil Ghodbane is a little embarrassed about the scene that unfolded when he met Peter Higgs. “At the time, I was maybe a bit naïve,” he admits bashfully, as he recounts a tale of waiting outside the toilets after a Scottish summer school talk to greet Professor Higgs on his way out. “We were like groupies!” he laughs at himself and other students who stampeded the reluctant physics celebrity.

“The first time I came to Munich, I fell in love with the city,” says Sandra Horvat. She was born in Zagreb, Croatia, and her parents and brother still live 20 kilometres from the city, in Samobor. “It's a lovely and cosy place, one of the oldest and favourite recreation places for many Croats. I like it a lot!”

As an ATLAS physicist, it’s not often you get to stand back and look at the bigger picture, according to Richard Teuscher: “Not at all! It’s only really when you get a chance to talk to someone about what you’re doing. Day-to-day, you’re writing software or fixing some part of the detector. But at the end you think, ‘Wow, look what we’ve done!’"

Moscow has been home to Lidia Smirnova for as long as she can remember. She was born in Ukraine, her mother’s region, shortly after the end of World War II. Her father, from Siberia, had served five years in the thick of the fighting, on the Soviet side. “He was wounded twice, but was really lucky to be saved with his life,” says Lidia. He was also very lucky to be stopped in Dnepropetrovsk, Ukraine, on his way from Germany to Japan. In that summer, 1945, he met Lidia’s mother.

Most people at CERN know Claudia Marcelloni as the ATLAS photographer and the exquisite eye behind the ATLAS book, Exploring the Mystery of Matter. But to Claudia, photography is just one tool that she could use to practice her passion: the creative communication of ideas.

Born Jorge in Argentina, George Mikenberg is a man of many aliases. He changed his name to the Hebrew Giora when he settled in Israel, but in English-speaking company, he encountered a problem: “The Anglo-Saxons cannot pronounce it, or rather they pronounce it in a way that means WC in Arabic.” And so he became George, but also Georg for the German-speaking, and Georges for his French-Swiss wife.

For Jochen Schieck, monthly trips to CERN – often spanning just one day – suit him well. The rest of the time he’s based at the Max Planck Institute (MPI) of Physics in Munich.

Particle physics is an endurance sport. The building of ATLAS took nearly two decades of design and construction. In the early autumn, the blast from the first colliding particles will mark the start of a multi-year race to discover new physics. This rhythm of preparation and performance is one that Adele Rimoldi knows well.

Osamu Jinnouchi had never left his native Japan when he first came to CERN, as a summer student with KEK, aged 25. “I don’t quite remember, but it was all impressive,” he ponders. “Everything was different here.”

Mountains are an enduring presence in the life of Marco Aurelio Díaz. “Wherever you are in Chile, the Andes are there, and they make an imprint in your mind that time does not erase,” he explains.

Harry Potter fans can probably sympathise with Helenka Przysiezniak Frey’s initial reaction to being profiled for e-News. “My husband tells me: do it,” she wrote in an email, but her latest reading material had left her with some reservations: “[The Harry Potter] equivalent of ATLAS e-News, the Daily Prophet, says all kinds of lies about Harry and co.”

How does Borut Kersevan spend his free time? “What free time? is the answer,” he says with a wry grin. But what little he has, he likes to spend on family, travel, and good conversation.

Salsa, singing, sight-seeing and skiing are all high on the list of ways to relax and unwind for up-beat PhD student Laura González Silva. “Dancing, I loved it always. I try to go as often as I can,” she smiles. Back in her hometown of Buenos Aires, Laura was part of a choir too, but in Geneva her vocal talents are mainly consigned to karaoke bars or her shower. “Singing and dancing – they’re a part of me,” she grins. “I forget about everything. And it’s good after spending ten-hours-a-day in front of the computer!”

In his more laid-back free time, Stanislav Němeček enjoys good detective novels and a production about a fictional Czech genius by the name of Jára Cimrman. The legends of Cimrman began in radio shows but later became plays in two parts: a lecture by a “professor” about recently uncovered work by this scientist/inventor/writer/philosopher and a scene played out by actors. The idea of Cimrman has been around since 1966, beginning as sort of a comic, literary protest to Communist rule. New episodes are performed every few years. Though a fictional genius, Cimrman is a symbol of Czech pride.

It was Santa Claus who first introduced TileCal data quality coordinator Andrea Dotti to “serious science”, when he was just 12 years old. “Since I was a small kid, I was more skilled in maths,” he explains. “I never liked to learn poems by heart, history was not my thing…” But the year Andrea received a chemistry set for Christmas he was immediately hooked, his interest fostered by a kind elderly pharmacist who sold him supplies.

You may already know the head of the Secretariat, Connie Potter, but you may not be familiar with all of the women who help keep the ATLAS collaboration running smoothly. Sitting around a table with Petya Lilova (Bulgarian), Kate Richardson (British), Christine Demirdjian (French), and Claire Gibon (French), the team of the ATLAS Secretariat, the first question was: “What work in ATLAS falls to the Secretariat?”

Even after 40 years living between Britain and Geneva, New York is still audible in the voice of Eric Eisenhandler. He grew up in the Bronx – “the North Bronx” he quickly corrects, lest we imagine the violence and urban decay that South Bronx came to symbolize.

Physics, as a discipline, isn’t short of references to symmetry and balance. The tale of Anna and Lucia Di Ciaccio though is almost poetic in the way it weaves. They are non-identical twins, and interviewing them is both slightly surreal and a complete delight.

Anna Kaczmarska is an artistic Polish physicist working as a software developer of the official ATLAS software package designed to detect tau leptons. Since Anna was a teenager, she has loved medieval arts: literature, architecture and music, whose rhythms, she says, help her to program ATLAS software.

“I think the money put in the summer school is among the best ways that CERN has to invest money!” says Jonas Strandberg, a Swedish physicist working on the Muon Spectrometer and Higgs Physics at ATLAS. He is another good example of the power of the CERN Summer School in drawing outstanding students into particle physics; since Jonas first came to CERN in the summer of 1998 as a physics undergraduate student, he always wanted to return.

“I’ve always been an outdoors person,” says Chris Oram, echoing the sentiments of many an Alp- and Jura-hiking CERN physicist. It may come as a surprise that he spent years of study in central London, starting out at Bedford College, London University, which stood in one of the city’s largest parks. He studied physics there and proceeded to Queen Mary College of London for his PhD. However, he did his research in Vancouver, Canada.

For SCT Project Leader, Pippa Wells, thoughts of precision, timing, collaborative working, and getting things to work in harmony are familiar to her both in and out of work. Her passion is playing the violin – specifically in orchestras. “It’s always been playing music with other people that has motivated me,” says Pippa, who picked up her first instrument when she was just six years old.

If the ATLAS detector assembly could be compared to a marathon, then Amelia Maio would be best described as a long-distance runner! This Portuguese physicist and Associate Professor at Lisbon University has been involved in the design of the ATLAS detector since its very conception. In addition, since the late 1980s, Amelia has also been a very active ‘outreach’ physicist.
