The campus never sleeps
While most employees and students are heading home, the late shift is just beginning for some. We take a look at a night at ETH Zurich.
“Which 95-year-old announced his retirement from public life today?” asks Brett Stirling. He is in the middle of running a pub quiz in the Alumni Lounge. It is 8 p.m. Many ETH members are rounding off their day with a quiz here on the H?nggerberg campus. While the teams put their heads together to discuss the answer – wasn't it Prince Philip? – restaurant manager Nurcan Inak explains her concept for the Alumni Lounge: “We hope our events will encourage people to spend more time on the campus.” From the autumn semester onwards, there will be a daily programme of events including live music, games evenings, karaoke and exhibitions. The lounge already hosts events several times a month and it is busy on evenings when there is nothing planned as well. “People come here to chat, work and switch off,” says Inak, placing the caipirinha she has just prepared on the bar. “Many of them come after a sports match or training session and stay for a beer.”
Loch Ness next door is a good place for beer too. On this particular evening in May they are holding a beer festival, with 15 beers from 10 different countries available to try. The smell hits you as soon as you walk through the door. It is busy, loud and dimly lit. Tim Kappeler, an architecture student in his sixth semester, organised the party. The bar is run by the AIV (the civil engineering students association), a VSETH association, and is open every Tuesday and Thursday. “Everyone who works here is a student. They work two to three times a semester for free,” says Kappeler. This is no surprise, given that the bar doesn't make any profit with its prices: “This is by far the cheapest beer in Zurich,” says Chris Vinck. He has come straight from the ASVZ gym and has dropped in on his way home.
The gym in question at the H?nggerberg Sport Center is still busy. It is now 9 p.m. It is slowly getting dark and it has started to rain. The people here are mostly men, lifting weights, using the fitness machines and doing sit-ups on the mats. In the sports hall, meanwhile, a handball training session is taking place. “You have to run faster!” shouts the trainer. “Let's go! One more time!” Sweaty and red-faced, the players dart around the court. The ball flies back and forth until: “Yes! It's a goal!”
There's lots still going on in the adjacent rooms as well. Salsa, ballet, taekwondo – all of the courses are well attended. The Sport Center is open until 10.45 p.m. on weekdays. While some people are celebrating, others are still sweating.
Security and order
A 69 bus is driving up to the bus stop. Despite the late hour, it is bringing a good dozen people to the campus. “In the last couple of years, we have seen an increase in the number of events. That has led to more night-time disturbances,” says Christof K?rber from the security service of the Safety, Security, Health and Environment department. He has been working at ETH Zurich for 19 years. Today he's on the late shift. In the HCO car park, he checks the delivery entrance for the Chemistry department. “That needs clearing away,” says K?rber, pointing to empty containers stacked up against the wall. Behind the containers is the emergency shower which is used in the event of chemical accidents. “Otherwise you could lose valuable seconds in a contamination situation.” During his shift, he makes sure that all doors are locked and escape routes are clear. Alarm calls are received by the Emergency Desk first and are then forwarded on to him. Many are of a technical nature – if, for example, the ventilation or another system in a room stops working. In laboratories in particular, this can lead to dangerous situations.
“Hi, this is the ETH security service. We're locking up now, if you could make your way out please.” K?rber comes across lots of people still working in the computer rooms at this late hour. “Before the exams, you notice the nerves in the students,” says K?rber. In the architecture department's drawing studio in the HIL building, you would hardly know it was 11 p.m. Project deadlines are coming up and the room is full of students working on their models. It's a scene of creative chaos. The tables and floor are covered with scraps of paper and tubes of glue, along with crisps and empty drinks bottles. “We'll get the last bus home at 1 a.m.,” says Cilgia Salzgeber, a first-year architecture student. She'll even be pulling a couple of all-nighters right before the deadline. On these occasions, she only has time to go home for a quick shower before it's time to get back to university again.
There are people still working in the HPK basement a few buildings further along as well. In the biology department, the nuclear magnetic resonance spectrometer is working at full speed. The machine, which is around four metres tall, works all year round without interruption. Its job is to analyse tiny samples of substances such as isolated proteins and active components of medicines. “It enables us to study even the weakest signals from atoms and atomic nuclei,” explains Alvar Gossert from the Institute of Molecular Biology and Biophysics. Every few nights, there are doctoral students or other institute members on site. They take the narrow test tubes containing the samples out of the machine and replace them with new samples. They have to make sure that they are not wearing anything metallic before entering the room, because the machine generates the largest magnetic field at ETH. It would stop a watch immediately.
It's the same in other departments such as the Departments of Materials Science or Chemistry and Applied Biosciences – the research never stops. There may only be people on site on rare occasions, but the machines run day and night. The campus never sleeps.
Polyterrasse in the moonlight
It has stopped raining. At 2 a.m., the sky is full of stars. Only the odd light is still on in the student accommodation. The security service patrols both the H?nggerberg and Zentrum campuses all night long. Partygoers finish off one last beer as they make their way home along the Polyterrasse. In the morning, the cleaning staff will have to pick up their rubbish.
The bQm bar closed a couple of hours ago after a DJ set earlier in the evening. The ETH main building is dark and quiet. But there are still a few tables occupied: some students are working through the night to prepare for their exams.
For the staff at the Polyterrasse canteen, the new day starts around 5 a.m. The kitchen crew of catering firm SV spend hours producing takeaway products, baking focaccia, tarts and biscuits and preparing the lunch offering. “During term time, 2,500 people eat here every day in the main canteen alone,” says purchasing manager Mio Grbic. At the same time, the staff in the kitchen under the Polyterrasse also make products for lots of other SV facilities all over Zurich.
Outside, it's getting light. One lorry after another pulls up outside the delivery entrance in the underpass. Some days the men bring a few hundred kilos of food, other days it's several thousand. Today is a fairly quiet day. “The most hectic time is November with ETH Day and the Polyball,” says Grbic as he checks the delivery. The temperature of the frozen berry mix is minus 20.6 degrees. Perfect.
In the main building, Rolf Isaak from the security service is starting the early shift. It was a quiet night. The doors of the ASVZ Sport Center opened again at 6.30 a.m., and the early birds are already back on the exercise bikes. Meanwhile, Isaak patrols the buildings, checking whether any walls have been defaced overnight, making sure the fire brigade access to the Polyterrasse is clear, and checking entrances and exits with his huge collection of keys. He covers many kilometres every day on his rounds.
While Isaak makes his way to the buildings on Gloriastrasse, the café bar in the foyer of the main building has just opened and the first customers have already arrived. They are getting ready for the day ahead with coffee and croissants. One bleary-eyed student gathers together his things and heads for his first lecture. A new day is starting.
