    Bergkirchweih(Berg)

    A hill with enough Beers for a fortnight! That’s what it is. People from far and near come to this event, the entire city seems to be in hangover from all the alcohol. In short: Good music, Good Beer, Pretty girls in Dirndl and ugly drunk men in Lederhosen all around!

    View from my house

    I too wanted to be a part of this. Primarily because of the fear of missing out (FOMO: a word I recently picked). But I wasn’t even sure I would enjoy it as much I eventually did.

    The thing is, I don’t drink beer and some of my friends had already visited this place. I missed out on joining them on the first two days of the fest. So, finally when I wanted to go, this Monday, there wasn’t much enthusiasm left.

    Fortunately, my apartment mate -Ananya- hadn’t been yet, so I planned to join her and her friends. Also, a friend of mine Felix, who had been there 3 days in a row and is now sick, also agreed to join.

    The Bergkirchweih

    The Bergkirchweih is an annual fest in Erlangen held on top of a hill. It is a religious festival. Or is it a beer festival? After all, Beer is the religion here. So, I guess it is still technically right to call it a religious beer festival. There is a church somewhere on the top – hidden behind thousands of people and liters of beer.

    It lasts 12 days, and place is filled with festive mood. The highlight is the beer cellars in the hill. Historically, beers were stored in it to keep it cool. Today, despite modern refrigerator technology, they remain the most important place of worship.

    This is similar to Oktober fest. But it is a bit older and more local festival.

    The wakeup call

    So, after a heavy lunch, I had fully surrendered to an afternoon siesta, when my apartment mate arrived. She knocked on my door and Anton was with her. I got up a bit grumpy and disoriented.

    I knew I had to get through this evening. I had committed to going to the Berg. Half unwilling, I dragged myself. The biggest fear wasn’t the crowd or beer… it was someone casually saying “You missed all the fun” and silently judging me as “You have failed as a social animal!”

    I told myself, I will return back in 2 hrs or less, just enough to pay my pilgrimage and click a few photos to prove I was there.

    The Walk

    But from that low point the day kept getting better as we moved closer to the hill. It was as if the hill has some magic.

    To begin with, Anton is always a pleasure to talk to. The conversation was already uplifting. With us trying on the caps and him explaining about the festival made me excited to go.

    With him, we took the bus toward the Berg, officially beginning the journey.

    On the way, we met another friend of Ananya at the Erlangen station – Maja. It was very refreshing to meet her. Possibly, the first person I know here who is not studying STEM, which automatically makes her 34.8% funnier.

    From there, we decided to walk towards the Berg together.

    Finally, Felix – late as always – joined us when we reached the Berg. I was glad to have him here.

    Walking Through Berg

    As we walked to the top we hit a T-junction. We started right – the PG version of Berg with rides and games. One ride called the Predator stood out as soon as we saw it. I made a mental note to ride it.

    Then we went to the left of the junction – the 18+ version. This is were all the cellars were – the beers and the music. We found a spot and we enjoyed the music for a long time.

    While we were there, we conducted a small scientific experiment. The Drindl that the girls wear, supposedly indicates if they are single or committed. If the knot on their waist is on the left they are single and if to the right they are committed.

    So, we naturally resorted to counting them for sometime. A bit of a questionable behavior. But since we were a mixed group, I hope it would have passed as a valid science experiment. The findings : roughly 50 – 50. A good news!

    The Ride

    This was the highlight of the day.

    On the way back, we decided to try those rides. So, it was jointly decided to get onto the 85-meter “Aeronaut” chain flier. A carousel which rotates at 85m high.

    I agreed but a bit sad as the Predator was cooler. But Aeronaut with friends anytime beats Predator alone.

    It was genuinely fun and from that height the view was unreal.

    The surprise came after: Maja wanted to ride Predator as well. So now it was Predator with a friend, which obviously meant it had officially leveled up—so I was sure it would beat Aeronaut.

    We dashed towards it and took the ride. It was shit scary. I have never in my life have been turned upside down and spun around. The ride was also much longer. But it was worth every penny.

    The return

    Felix decided to stay longer at the Berg. He apparently stayed till they closed and then went to a club. Reached home very late. And that explains why he is sick today!

    Rest of us walked back. On the way back, Maja explained why I get to meet her after 1 semester of being in Germany. Most of my connections come through Ananya. Maja calls herself “top-tier unlock”. In her system, people are arranged like game levels, and you only unlock the higher tiers after enough time, trust, and a few completed side quests. I apparently made it to this level only after a full semester.

    Eventually, it was time to part ways. It was far longer than 2 hrs. But, at this point I was no longer eager to reach home.

    We waited for Anton to board his train back home. Ananya then suggested walking back home and I readily took that option. That at least delayed reaching back home by 40 more mins.

    A day to remember!

  • May Day

    May Day

    Start of May had been exciting – a hike, badminton, pizza and spike ball! That was my how the month started.

    Walberla

    A long weekend was ahead of us. We wanted to do anything but stay home. So, on the suggestion from my roommate, we decided to head towards the Frankonian Swiss.

    This place is called Walberla. These hills are roughly 20 kms and are visible from my high rise apartment.

    The hikes are always interesting with more people. So, we sent out invites. Some were lazy, while a few others occupied as they had their own plans for the long weekend. Finally, we were able to gather 10 people who made up their mind to join the hike. On the day of the hike, however, only 5 turned up.

    The smaller group had its own charm. We could get to know the two new friends better.

    To our delight we chose the perfect day to travel to Walberla. May 1st sees huge crowds arriving to Walberla for Walberla festival. Originally, it was a pilgrimage and church festival at the church at the top of the hill. But like all things in Germany now, it is more about the hike, Beer and food stall.

    Hike

    There was good connectivity from Erlangen to Walberla. I am not sure if it is like this all year round or just this time of the year due to the festival.

    A short train ride from Erlangen to Forscheim followed by another short ride to Kirchehrenbach brought us to the foothills. The train ride took us less than 30 mins and we were teleported to this beautiful landscape straight out of windows wallpaper.

    The hike was easy. We took a slightly longer way to walk around the hill to finally climb the hill. On the way, we could see my apartment. Then there was a huge cross and soon we arrived at our destination.

    There were a lot of beer and food stalls. And A LOT OF PEOPLE. We were surprised to see so many. It has been 6 months since I saw so many people together in one place. This view brought memories from my home country.

    Hidden between these shops was the small church – The church which was supposed to be the center piece of this festival. Now it looked almost forgotten. We also forgot to click take any photos of it 😆

    Food

    After the hike we were getting a bit hungry ourselves. The ice cream stall was very inviting and so we started with it. It was a bit expensive as expected – 1.5 Eur for a very small scoop.

    Then we found a place and settled there. We ate some food that we had brought from our homes. But the highlight was the surprising treat of home baked cake.

    One of our friends in the group teaches math to a German school kid on Sundays. This family had also come to the festival. We met them and they offered some cake that they had baked. Usually, I don’t enjoy sweets but this cake, I liked!

    Sun Burn

    The pleasant warm weather was very welcoming and we spent a long time lying on the grass. We did not realize that the cool breeze was hiding the strong intensity of the sun rays. That, along with the clear skies in Germany makes it notoriously easy to get sun burns.

    None of us had sunscreen on us. The effects of which were felt over the next days. The change in color was quite immediate but the skin only started peeling off after 2 days.

    Yes. Now we have our lessons and our sunscreens.

    Return

    The crowd kept getting denser. People would stay here till late evening. We decided to head back before the trains get crowded with so many people returning.

    I also have been carrying a boomerang with me ever since I got it. This was roughly 5 months back. Finally, we found some space to play with it. There was an open field and we played for sometime.

    We got on a train back and reached Erlangen quite soon. We still had reserve energy left when we were at the station. The sun also wouldn’t set for another 2 hours or more. So we decided to head towards this open space along side the river.

    After 2 long hours of chit chat it was finally time to head home. I decided to walk back home. That was another 40 mins and finally I made it home at 9. A bit tired but excited about badminton the next day.

  • Phew!

    Phew!

    One semester down! Last few months were very busy and I see that the last time I posted was in January. A lot has happened in the meantime and I might write about those in the coming days.

    Let me begin with writing the things that I remember the most. The exam period! One of the most hectic exams that I have answered in my life.

    The Timeline

    The lectures ended on the first week of February. I also had the first of my 6 exams in that first week. The last exam ended three days ago on 9th Apr.

    In between these 3 months there was a “Break” of 1 month. But it is hard to say exactly when it was. It was somewhere between the mid of Feb to the mid of March. I know I had 2 exams before the break 3 after. I think 1 was during the break. And there was a week of Labs during the break.

    During these months, the weather changed from snowy to warm and pleasant. That is from -10ish to 20ish.

    The Grind

    Looking at this long timeline one might feel there is sufficient time to study for exams even if one hadn’t started before. But I strongly disagree.

    Coming from India, the exams feel really hard. They are very challenging and unless one understands the concepts clearly, one can’t pass. This is what I was told on my first days here. It is 100% true and I can also vouch for it and say it to the next batch.

    Roughly, we had 2 weeks on an average between each test. Except for the first exam which we started studying in January and that gave us 1 month.

    The days were extremely boring sometimes. During this time we tried to study in group. The group study time was something to look forward to in a day. That was a time to discuss what was studied, try to solve questions together and most importantly gossip a bit. The banter with friends made the days bearable.

    The study consisted of going through the lecture notes, tutorials (solved numerical examples) and solving old question papers. During this process we understood that they teach us A, B, C, D.. in class. Make us practice writing sentences in the tutorials and in the exam they expect Shakespear out of us. (Not my wordings, I borrowed it from some acquaintance I met in bus! But I can’t say it better.)

    The confidence level during the process starts high when you know the lecture notes. Then it drops slightly when you try to remember the tutorials. And crashes and goes underground when you start solving the exam questions. Finally, after 15 or so question papers you feel you are in a position where with enough god’s will there is a chance to pass. In that final state you answer the exam.

    The Exam

    Every time on the exam day the mental state was more or less the same. You wait for your friends to join you at the exam center. If the exam is after lunch then we met earlier at the Mensa (the canteen).

    The tutors enter the exam hall first and generally make markings, which lets us know where we are allowed to sit. The halls are huge and everyone is spaced apart. When the time comes we are allowed to enter the room. There is no dedicated place and we could choose the seat freely.

    Then comes the announcement. It reminds me of the first time when I took the flight. The flight attendant reads out the instructions about the emergency doors and life vests. I listened so intently thinking I might really need it if the flight crashes.

    Similarly, here the tutors read the same instruction before every exam. Some interesting instructions were: if anyone is feeling sick then you must tell now and you can leave and get a medical certificate. If you get sick after the question paper is distributed then you can only get the medical certificate from the doctor that the university suggests!

    The way they explain it, getting sick before the exam is a medical issue; getting sick after the paper is distributed is apparently an academic offense.

    My performance

    Answering exams after a long time comes with some challenges. I noticed I have forgotten the exam answering skills. I constantly made silly mistakes, like for example copying a different value from the calculator to the notebook or changing + to – etc.

    These mistakes aren’t new but earlier I was better at catching them early. With time and constant use of computers, I realized I have lost this skill. This has hurt me the most through the exam.

    Most exams also allowed carrying cheat sheets or textbooks. As I was not used to using these, I wasn’t very effective at using these. Also my handwriting doesn’t help either.

    Most results are yet to come and I hope to pass the exams.

    End and the Beginning

    We celebrated the end of the exams by visiting the Volksfest. I performed a hard reset with a ride called “Brake Dance”. Then, the beautiful fireworks marked the beginning of the new semester. It was a wonderful evening with friends.

    I start my first class for the new semester tomorrow. Here are some photos and videos from the festival

    Wrap up : 2025

    Many years ago I had read an article about Abraham Lincoln. In some context, it mentionend “Rolling stone gathers no moss”. The phrase has stuck to me. I feel that phrase has quietly shaped my outlook and nudged me into being a bit more experimental in my life – sometimes intentional, sometimes by poor decisions.

    This year has come to an end, and it too has brought so many changes in my life. The transition from professional to student has been illuminating. It taught me an important survival skill – cooking. I am also getting more disciplined with time, just like so many other students here, who juggle between studying, feeding themselves, working and enjoying.

    But fear not. I will spare you the details. The rest of the blog is about the last month – The Christmas and the new year here in Germany.

Mercedes Museum

My winter break was between 20 Dec to 6th Jan. The first weekend was about meeting my friends from India who had come here. There is something deeply comforting about meeting known faces in a foreign land – it instantly drops homesickness by 37.5 % (They also bring be spices from India)

After a five hour journey, I met my friends in Stuttgart. As always, DB did not disappoint me. It gave my journey an adventurous start with new constructions and diverted trains.

Our first destination was the Mercedes Museum. It was bigger than I expected. The three hours that we spent in the museum did not do justice and I will have to visit again to understand it.

The museum takes you through a timeline, from the oldest to the latest cars. The tour starts on the 9th floor and one has to walk your way down. Every level advances you through the timeline.

I am not a car enthusiast so I don’t know the details of the cars but I can definitely say I can never buy one of those. Some are out of stock others out of range.

Christmas Markets

Christmas Markets are temporary markets that are setup for 1 month before the Christmas. It is about colorful shops, games, drinks, food and lot of people. I tried visiting a number of markets because each market has a different theme and energy.

Stuttgart

I tried the Glühwein (It is a wine which is hot and mixed with spices).

Esslingen

This market was themed like medieval period. The people were also dressed in that theme. Unfortunately, I did not get photos with them. But I have photo with my friends!!

A small hike in the city brought us to this amazing view of the city. The steep hike, on the other hand, led us to collectively scolding the person whose idea it was in the first place. You can try to guess whose it was from the picture. (Comment below and I will tell you if you are correct)

Fürth

This was another Christmas market which was also fashioned as a medieval theme. I enjoyed the most here. I was with a friend, had more time and there was music and axe throwing.

Nürnberg

I was alone here. So, I just made a quick round. It was OK! Not bad, not great.

New year’s Eve

The new year evening sounded suspiciously like the Indian Diwali with fire crackers everywhere. Like even on the streets.

I started watching the crackers go at 6 PM from my room in Erlangen. But the real fun began at midnight. Me and my friends went to the neighboring city of Nurnberg, expecting more action.

The city did not disappoint us.

We emerged out of the train station at Lorenzkirche 15 mins before 12. It welcomed us with a complete chaos and madness.

There were rockets bursting everywhere. I always thought Germany was a rule following, human life and safety critical country. But this one hour made me question everything.

Every 20 meters or so, there was a guy lighting a rocket from the hand. If you weren’t careful you might just get launched along with the rocket being lit next to your leg. Nobody even warns you!

This loud madness of rockets on the sky, ground and everywhere continued for 1 hr. The rockets kept hitting the buildings along the street and residents watched the rockets calmly as it approached their faces – protected by the closed window. They clearly were expereinced in this annual ritual.

Post new year

The shortest day passed on the 21st Dec. The shortest day was just 8hrs long. So the days could get only longer now. I was thinking it only gets better from here.

But I learned that earth takes longer to thaw. And it gets colder in January.

The first week of this month has been very cold, averaging around -2 deg and going as low as -10. With it, it also brought lot of snow which I enjoyed. Especially, given the fact that I did not have to step out of the house.

Things will change tomorrow when my university starts again. So I will walk in the cold.
