30.3.10

this is how the end of the world looks

Hairs fly, speed of light,
Crunch crunch crunch through huge machines.
Science is reborn!


First:
http://twitter.com/cern (Henning notes that inside the 10 minutes around the first collision, CERN on twitter gained 4000+ followers)
http://webcast.cern.ch/lhcfirstphysics/ (the main webcast is really slow right now due to high demand ;))

At around 13:00 today (Geneva time), the LHC recorded its first collisions at 7TeV!
Happy physicists

Pretty events
Woohoo, us!

2.3.10

darmstadtery & the like

Xynthia's blowin'
My kite up in the sky, now
Push the big button!


The LHC is go, my friends!  And any time you want to know, just check out lhcportal.com or meltronx.com.  They've got the lowdown.

Today I got a tour of CERN's Control Centre, which is located in a big room on the secondary campus.  There are 4 "islands" where people control every accelerator at CERN, and there are a lot of accelerators.  There's a map on the wall in the conference room that shows how they're all hooked together.

Fun things:

  • The LHC runs a "beam" which is comprised of 2800 smaller beams
  • Each small beam is 20cm long and has 10¹¹ particles in it
  • There are 3 metres between beams
  • The magnets that steer the beams are kept at 1.7K (that's -271.3C or -456.34F... damn cold)
  • It takes 4-6 weeks to warm the magnets up or cool them down for repairs and stuff
  • The LHC tunnel is 27km long, 100m underground
    • It was previously used for an accelerator called LEP
  • The guys who maintain the physical equipment like to get around underground on bicycles
  • There is a big box with lots of red buttons in the control room
The dude who gave us our little tour knew what he was talking about, and I learned a lot from it.  :D  He also offered to lead tours of any friends who may show up, so if you guys are thinking of coming to Geneva any time before April...

Other than that, I had a weekend!  I went to good ol' Deutschland to spend it with Olex and Julius: my friends from my days at TU Darmstadt.  We went to a snowboarding and skiing tricks competition, ate food, drank beer, played Risk, played Left 4 Dead 2, cooked food, watched movies (Meet the Spartans, The Book of Eli), played Jugger, and flew a kite.  I also finally had an opportunity to upload more photos: you can see them in my Picasa album or on Facebook.

There was a huge windstorm this weekend: it's been named Xynthia, and I guess it killed several people in Western Europe (particularly France).  It also closed all the train stations in Hesse (the German state that Darmstadt is in) for about 15 hours, so instead of leaving on Sunday afternoon, I took a train at 6am on Monday.  Uuuggghhhhhhh... going to work with no sleep is the worst.  Flying a kite in gale-force winds is the best.

But that's nothing compared to the earthquake that happened in Chile, I guess.  8.8 on the Richter scale, and it shifted the earth's axis 8cm and shortened the day by 1.26 microseconds.  Sure, you won't have any occasion to notice those things, but Earth is flippin' big.  It's amazing that it managed that!

This week has a few things I'm excited about, too:
  • Pub Quiz yesterday!
  • CERN Control Centre tour today!
  • D&D tomorrow!  (Well, okay, it's some knockoff of D&D from Germany, but it is reputed to be just as fun :D)
  • Board games Friday!
  • Zürich Saturday/Sunday?  (Looking for anyone else who might want to go?)
  • Joe arrives on Sunday!
Hooray!  ^_____^

cern mysteries

Particles! Bang, crash!
A silent spinning circle
Metres below me.


There are some weird things about CERN.

The silverware in our cafeteria is magnetised.

We have the Internet in a yellow tube.

There is a button in my office which is labelled "LHC on->* off->*".

The light in the main auditorium is actually two switches. One switch is flipped for the light to go on. The other is flipped for the light to go off. Either way, doesn't matter.

There is a floor design near Restaurant 1 which seems to represent the accelerators at CERN, but no one seems to know how: relative size? Shape? Connectedness?

Just try walking around there. Just try it. If there wasn't a big, thick, black line on the floor from the front door to practically my office, I'd never have a shot at getting to work.

hourly comic day

For those of you who might not know, Hourly Comic Day is 1 February.  Some people like to do this sort of thing.  I figured I'd try it this year.

In case they are impossible to read...
0,0: "Oh, shit.  It's hourly comic day." (me) and "Google Reader, HOURLY COMIC!" (screen)
0,1: "What the hell is that?" and "What if it takes 2 hours to draw?" and "Not many people seem to do this." and "Coffee?" and "Okay."
1,0: "I pledge allegiance to the flag..." (me) and "You really have to say that every day?" (Henning) and "American coffee + culture lesson" (bottom)
1,1: "Your passport is like a picture book!" and "Oooh!  Is that a story on top?" and "Why's there RFID in that?"
2,0: "Don't forget to bring your comic to lunch." (Piotr) and "I will just do with when I get back." (me) and "That's not very hourly." (Piotr)
2,1: "I just spent $16 on this salad and sandwich." (me) and "Welcome to Switzerland." and "Coffee?" and "We code like girls and are proud of it!" (my shirt)

Again, in case...
0,0: valkyrie@asgard:~src/cds-invenio/modules$ git commit -a -m 'tarball harvester works and the extract plots thing has been modified to be more robust in the case of friggin pathological brace placement'
0,1: "Yup that is actually all I did" (me)
1,0: "Rock Musik - Victor", "Rock Musik - Henning", "Rock Musik - Piotr", "Classical - Roman"
1,1: "earbud cord" (with arrow) and "It is okay, Travis plant.  I do not have headphones, either." (me)
2,0: "My life is boring.  I have done nothing to write about this hour." (me)
2,1: "DARTS" and "I am bad" (pointing at the scattered darts) and "We have one in our office" (pointing at the dart board wall)

30.1.10

work is play

Sitting down, sifting
Through, sending chats, emails, too,
Work is play.  It's true.


The European work ethic is not a joke.  We really do take a full hour (sometimes more!  gasp!) for lunch, with coffee breaks of half an hour or so in both morning and afternoon.  We arrive at 9 or 9:30 and leave at 5:30 or 6.  My first week, I would come in to an empty office at 8:30 and sit by myself for an hour before anyone else arrived, and they were all convinced that I was a crazy, workaholic American.  I wonder why we condition ourselves that way in the states?  It varies from industry to industry, too.  I know at Google we had a really great environment that encouraged people to be happy... and to stay as long as possible at the office, working.  I was on campus for more than 14 hours some days; after work, why not just stay for Frisbee, dinner, pool, a movie, and some Rock Band?  It was especially tempting for interns: we didn't have apartments that were furnished in particular, and getting to the City took an hour, so...

But the atmosphere at work is amazing for other reasons, too!  Maybe it's just because I'm new here and haven't had the chance to make many other friends, but the people I work with are definitely more than just "the people I work with."  We go skiing on the weekends, out to shows (we went to see "The Importance of Being Earnest" by Oscar Wilde last night, which I highly recommend!), out for drinks, etc.  This weekend some of the guys are having a LAN party.  I get to talk to Joe a lot of days.  His boss takes him rock climbing, and keeps tabs on my apartment search (which, I do believe, is at an end now, finally).  We spent an afternoon building a snowman and having a snowball fight when CERN was buried under inches of the fluffy white stuff.

I guess I think the best work comes from happy people.  There's no shortage of intellectual stimulation; hell, the tables at Restaurant 1 are covered in visualisations of results from some of the experiments (ISOLDE, etc.).  There's a club for nearly everything: skiing, ballroom dancing, boxing, scuba, tai chi... dang.  Everyone uses personal email and work email interchangeably for communication; we sit in chatrooms with our GMail accounts and send event invites from our CERN accounts and... well, heaven only knows.

Well, in other news.... what.... I have an apartment to live in (14 Rue Jean Dassier, 1er étage), which I will be signing for tomorrow, assuming that I can acquire a legal paper that states that I am a Good Person.  That's kind of weird, but it's fine, I guess.  Today I'm planning to get a tour of the UN if I can: my roommate right now is a UN intern working at the German consulate.  Pretty awesome.

Still working on that camera thing.  It's really a shame that xD is incompatible with Linux.  I'll find someone with a Windows laptop and a card reader as soon as I can... eeps.

hunting and gathering

Basking in the glow
Of SCIENCE, mes amis, one
Can stand to learn much.


So the whole someone-else-will-get-an-apartment-for-me thing seems to have fallen through, and I'm neck-deep in French and English websites, trying to find a damn room for four months.  If you know of anyone who is looking for a temporary roommate, do let me know.  Interesting fact: roughly 80% of the people who live in Switzerland rent their homes/apartments because it is so damn expensive to buy them.

I am learning more and more about CERN during my time here (surprise!).  There's a lecture tomorrow morning about the LHC that I'm thinking I'll go to.  The LHC is definitely off right now; my team and I were talking about it at lunch, and I guess just that machine draws 20% of Genève's power, so it is off until springtime when human beings don't need energy for doing things like... heating their houses.  What else... oh, yesterday I got to see CERN's server farm, including the backbone of the Internet (for this region of Switzerland)!  That's pretty sweet.  It's a bunch of fibre-optic cables in a really obnoxious yellow case.  There are huge cooling units in the room with all those servers, and one of my friends who works there said that if the cooling units go down the temperature can rise 1 degree Celsius per minute.  That's hot!

One of my lovely coworkers, Jan, has offered to lend me one of his bikes for the time I'm here.  I got to ride to the grocery store!  It's super fast!

I also got my first letter from home today.  Hoooooooray.  Seriously, y'all, feel free to send things to my desk.  Or, if you want a postcard from lovely, mountainous Suisse, send me your address.  :)

13.1.10

how much snow does it take to shut down a black hole?

We are serious
Scientists.  LOL, J/K.
We built a snowman!


First, thanks to Venus for the post title, and thanks to Nadège for the first part of the haiku.  And for the non-1337 among you: LOL and J/K.

Last night, CERN was buried under an additional 18 or so cm (that's 7"!) of wet, perfect, packable snow, which effectively closed the place down.  My boss didn't show up for work.  The cafeteria was empty at lunchtime.  The dudes on my team (those of them that showed up, anyway) and I spent some time this afternoon constructing a snowman and having a snowball fight.  We settled on teams of Northern Europe and US v. Southern Europe, but we discovered quickly that the southern Europeans were somewhat less cold tolerant.  Hahaha.

I also walked home in daylight today.  Well, near-daylight, anyway.  I could see the mountains in the distance, and, my, did they look fabulous.  Pinpricks of light were lined neatly along them, presumably following the roads, and everything was basked in twilight's purple-y glow.

I also finally got out for some exercise, gasp.  I jogged a few kilometres around the complex before realising that tennis shoes did not provide sufficient grip on ice-slick roads and coming home to do sit-ups (!) and push-ups (!).

Okay, I also have advice/info/comments for people who want to look savvy travelling in Europe.

  1. Bring assloads of passport-sized photos.  For whatever reason, every friggin card you want here (rail passes, work cards, blah blah blah) will require a passport-sized photo.  Or four.
  2. Beer is served in our cafeteria.  At lunchtime.
  3. Coffee breaks are key.
  4. The easiest thing to do (and this is in general, not just for Europe) with those stupid baggage tag stickers is to stick them on the back of your passport.  It seems like 25% of the times I fly now I have to change flights or something that requires the airline to check what's up with my bags.
  5. Carry a digital camera: when you don't have a printer or a fancy-schmancy iPhone, you can just take photos of on-screen directions and look at them later.
I'm sure there're others.  Uhhhh... I'll post them if I think of them.

I don't think there's any more snow in the forecast for now, but it's still pretty magical-looking out there.  Maybe tomorrow will bring another snowman.  Also, I have been talked into snowboarding instead of skiing this weekend, having been given the reason that skiing is "stuffy."  Since I'm not really awesome at snowboarding either... it's not a total loss.  ;)

first impressions

The world machine whirs,
Spinning up, in a frenzy,
Crash, ye particles!


As far as I know, the LHC isn't actually working right now, but that's not really the point. Okay, here is time for my impressions from my first two days here!

I guess I should go with factual things first: yesterday started with my being shut out of CERN for poor planning. I guess I hadn't been entered in the database yet, so I had to beg a woman to look up the phone numbers of the people I needed to contact. I called them, but they were both busy for a little while, so I hung out in the CERN swag shop. If anyone's interested, there are some pretty cool CERN shirts for around $20 US.

After that, I met with my boss, Salvatore Mele. He's Italian, and super smart. I guess he's known since early high school that he wanted to work at CERN. He's also published on the order of 300 High-Energy Physics (HEP) papers. For those of you not familiar with "published," that means that he was involved in the experiments in some way, not that he necessarily did all the work himself. Some papers have 2,000+ authors, and often papers will list professors or superiors as authors when younger or more inexperienced students have written them in order to get more exposure for the papers. But, still, 300 is damn impressive.

I also met my team (Inspire) and saw my office. There's a dart board and a big plant (I'm not sure what kind yet, but it looks vaguely tropical, I guess) named Travis. Travis is Joe Blaylock (my friend from school who got me this job)'s boss at the Stanford Linear Accelerator Center (SLAC) in sunny California. I'm sharing with 4 grad students, and there are 4 more in the next room. They are from all over Europe, and hearing so many accents again is kind of fun. :)

I got a CERN id card, which has a photo of me looking very attractive and jetlaggedly exhausted. I now also have an official CERN email address: valkyrie (.dot.) arline (.dot.) savage (@at@) cern (.dot.) ch (sorry, I don't want to get spam for posting that thing). I was pretty excited to add myself to the CERN network on Facebook, hahaha.

Then I met my temporary team (Invenio), since I guess the guy I'm working with on the Inspire team (which they call "the library team" here, for some reason) is in India for another week or so. Invenio is one of the things that Inspire is building on; basically Inspire is a project aiming to combine Invenio and SPIRES and add some extra search functionalities.  I found out exactly what my project is going to be, and although I haven't had to sign an NDA (a fact which I suspect stems from CERN's seeming... lack of organisation), I think I'll not babble about it here on the interwebs.

There are like 13,000 "users" at CERN.  There are 3,000 or so permanent employees and 4,000 or so visitors at any given time, so this campus is HUGE.  It can easily take 30 minutes to walk from far end to far end.  It's also situated right on the border of France and Switzerland, so my hostel room and office are in Switzerland but my temporary office is in France.  That's sort of a weird thing to think about.  I guess I'm going to be living in Switzerland (in an apartment!  yay!) soon-ish.  The housing coordinator woman from IU told me it would probably take about 2 weeks to find something.  In the meantime, if any of you has an itch to send me mail, my desk is an okay place to send it:

Valkyrie Savage
CERN
CH1211 - Genève 23
Suisse

Technically, my desk is 3-1-021, but I think it should make it with just that much address.

Now, impressions!  For being such a high-tech place, CERN is really low-tech.  I had to scavenge computer parts from abandoned machines just to have a workstation, which was sort of amusing, in its way.  A lot of the buildings seem to be afterthoughts (I guess this facility has been around for a really long time...), and the numbering system on the map is really screwy.  For instance, building 3 connects to buildings 4, 52, 53, 22, and 26.  Next door are buildings 304, 602, 100, 510, and 63.  I walk past building 2013 on my way to my office.

I'm probably going to die of radiation poisoning just for being here.  I was trying to discover some kind of short cut through the buildings between my hostel, which is on CERN property, and my temp office, and I ran into several dead endings at rooms marked RADIATION HAZARD.  So... that kinda sucks.  :)

Swiss people, as I mentioned, have no idea what to do about snow.  My boss almost drove instead of taking a 10 minute walk with me yesterday because he didn't want to walk through it.  He also informed me that Genève once had snow plows, etc., but gave them to another canton (kind of like Swiss states) when they stopped getting so much snow.  Now their plan for when it snows is... to wait until it rains.  Great.

Not much happens around CERN.  This hostel is full of visiting-professor-types, and once people go home for the evening--which tends to be early; Europe largely sticks to a traditional 8-5 workday, which makes this really unlike any other CS jobs I've had, i.e. Google where people usually come in at 10 and stay until... maybe 9--there's not much to do.  I am continually irritated by the fact that grocery stores close so damn early here, though today I learned that the closest one is within 45 minutes by walking of my room, so I could reasonably go there to procure calories when need be (as long as it's before 19:00).  I asked one of my temporary co-workers what he does after work, and his response was that... well... not much.  I guess that a lot of the grad students in this group are planning to go skiing this weekend, though, and they invited me to join them.  Hoorah!

There are multiple parts to meals here, even lunch.  I did not know this.  Apparently, one eats one's entrée, then moves to a different location for dessert, and another different location for coffee.  And by "coffee," I of course mean "espresso," since it seems no self-respecting Europeans take their coffees "long."

Now that I've had that little babble time, I guess it would be reasonable to wrap up this post.  Again, I hope to put up pictures soon, and also to post a permanent-ish address.

Cheers!
