Early Mornings and Late Nights

I'm late in posting and I'm very sorry!

I've been incredibly busy trying to come up with a way to calculate dispersion relations. I've also been busy making some noise in an aeroacoustics lab (see below). By the way, did you know that math is everywhere? Math can be so festive!

I have a few trips coming up. First, I'm going back home for for about a week. Then, I'll be in Prague for the New Year. After that, it's off to Munich and then to Zurich. SOOOO excited! It's probably going to be crazy cold, but that's okay. If I don't die from frostbite, I'll be sure to post some pictures. An added bonus is that I'll be flying with Icelandair on my way back to the US. Iceland seems like such a friendly little island, so I'm curious to see what their airline is like. Maybe they'll play Sigur Rós throughout the flight?

Lastly, here are some good words to remember in the wake of yesterday's events. Courtesy of Mr. Rogers:

"When I was a boy and I would see scary things in the news, my mother would say to me, 'Look for the helpers. You will always find people who are helping.' To this day, especially in times of 'disaster,' I remember my mother's words and I am always comforted by realizing that there are still so many helpers - so many caring people in this world."


At any given moment, this is what my computer screen looks like.

Soundtrack to Eating Scottish Seabirds


Classes have started. So far, so good. I took up a personal project that involves what is called a circular, hydraulic jump. You can see a simple example of a hydraulic jump by turning on your kitchen sink. The ring of water that forms at the bottom of the sink is the hydraulic jump. Well, it turns out that this thing appearing in your kitchen can be used as a model for the time-reversed equivalent of a black hole, aka a white hole. A black hole sucks everything up and nothing can escape, not even light. Well a white hole spits everything out, and nothing can get in. In the kitchen sink, you can see little waves traveling out towards the ring, but you don't see waves traveling in. Just like a white hole! Who would have thought that fluid dynamics is analogous with the weirdest, craziest things happening in the universe?

My professor sent me a bunch of papers to read. Papers about things like quantum field theory, general relativity, time-reversal, and Hawking radiation. These topics are things super insanely intelligent theoretical physicists study. One of the papers even calls Stephen Hawking's calculation of the event horizon temperature as "naive." I'm in way over my head, but I would much rather be overwhelmed than underwhelmed.


I went to Bordeaux. Twice! Once to go exploring, and once to see one of my favorite bands of all time, Godspeed You! Black Emperor. I've heard that there is a bit of a rivalry between Paris, the largest city in France, and Bordeaux, the second largest city. I won't add anything to fuel this rivalry, but what I will say that I really REALLY like Bordeaux. Of course, I made sure to try some wine while I was there. I also had a funny exchange with a bartender:

"Good evening. What kind of beer is the Waggle Dance?"
"It's a honey beer. You're American, right? Yeah, maybe you would like it."


My professor took some classmates and me to visit the Château de Clos Lucé. This was the place Leonardo da Vinci spent the last years of his life. Everyone knows Leonardo da Vinci painted the Mona Lisa, and that he's one of the Teenage Mutant Ninja Turtles (that's right, Michael Bay, both teenage AND mutant). However, he was also an engineer and an inventor. A really good one. Some of his inventions didn't work so well, but the principles they were based on made sense. Very impressive, especially for someone in his day.

Mon Aéroglisseur est Plein d'Anguilles


Classes start next week. The schedule is still being planned but, from what I know, I will be having Aeroacoustics (with associated lab), Advanced Signal Processing (with associated lab), Turbulent Heat Transfer, French Language, and a personal project in which I get to chose a topic to work on. I'm thinking combustion, maybe? These are all set for before Christmas. After Christmas, it's looking like I'll have a modeling class (RANS stuff), Stability, Compressible Turbulence, and more Advanced Signal Processing. Good God, these sound hard.

I've been in Poitiers for about a month now. During that time I've been exploring Poitiers and seeing all sorts of super old churches, hanging out at cafes, and studying French, often with funny results (see below). I'm planning on going to a city called Bordeaux this weekend. Bordeaux is pretty much the wine capital of the world. We'll see how it goes! 


Baptisére Saint-Jean, this was built in 360 AD and is thought to be the oldest church in France.

A super awesome cafe/library/bar. I'm planning on doing a lot of "studying" here.

Things shut down from 12:00pm to 2:00pm. Everyday. Lunch time is serious business!

This study method is giving me the wrong impression about France.

Don't listen to them, little guy. You can do anything you put your mind to. You're such an inspiration.


P.S. Here are some clips from an old British show called Trigger Happy TV. Probably the greatest hidden camera show of all time. Hilarious scenes complimented by great music.

El Hambre es Muy Feo


This is a story my dad told me.

My dad grew up in a poor family in Mexico. Often times he doesn't eat because they don't have money. On the rare occasion his family does have money, there is no food to go around. He doesn't go to school because his father doesn't think it's worth it. Not even for the girls. Everyone works.

When he grows up, he goes to Texas to look for work. It's a strange new place. All the white guys there speak Spanish. Better Spanish than him, even. He finds a guy to work for, but he doesn't know how to do anything. The farmer wants him to drive the tractor around. My father doesn't know how, but he gets on anyway. He gradually teaches himself how to drive it. He also does several little odd jobs. He learns some carpentry, he learns to paint, he learns a lot of things. He starts a family.


Years pass, and he moves to Washington because he hears there's good work. He arrives, and there are almost no Mexicans there; maybe 4 other families. None of the Mexican workers speak English, and none of the locals speak Spanish. Everyone is crazy racist towards him. He goes and looks for work cultivating potatoes. He finds some asshole farmer to work for who calls him names like dirty Mexican, and just treats him like shit. They can't communicate all that well, but the farmer makes the signal for my father to go drive the tractor. The farmer is surprised he knows how to drive it. His experience in Texas comes in handy.

Two years pass of living and working in Washington. Just by walking around town and listening to people, he learns English pretty well. Proper English, not vulgar asshole farmer English. One day the farmer wants his potatoes cultivated, so he tells my dad:

"Get your ass on the tractor."

My dad responds with, "Hey, I'm not gonna take shit from you or anyone else."

The farmer is surprised, "Oh! You speak English?"

"Yes, you taught me."

"Anyway, get your ass on the tractor."

My dad is tired of this guy, so he quits. It sucks for the farmer, because my dad is the only one around who knows how to drive a tractor. He's also the only one who knows how to extract potatoes. A few weeks pass by and the farmer still hasn't found anyone to drive his tractor. My dad has already found work somewhere else.

A few months later, my dad passes by this guy's farm again. He sees the farmer has finally found someone to work for him. A guy and his wife are extracting potatoes. Except they're doing it all wrong. Chopped up pieces of potato everywhere. Serves the farmer right, my dad thinks.


Years later, he's got a family of about 6 total. He hears about work in bean fields in Oregon. He loads up his family, and travels to a small farming town. They get into town, and it's raining. All the time. Rain forever. They check into a hotel and get a room. My dad then goes off to look for work in the morning. It turns out a lot of other people had the same idea as my dad. Mexican workers everywhere!

He meets up with a farmer that has a good 15 to 20 acres of beans growing. My dad is one of about 50 people working the fields. My half-brother at 11 years old is another. It's still raining by the way. All day, everyday. Fields of beans and rain. Once all the work is done, he goes into town and gets his pay. 5 cents a pound is the going rate. He got about $2.50; not very much, even in those times. He still needs to pay the hotel owner. Instead of taking his family to a restaurant for a hot meal, his wife buys a loaf of bread and some pieces of ham. She makes a few sandwiches and everyone eats them in the car. That is their restaurant.

Dad goes back to the hotel and runs into the hotel owner. The hotel owner asks, "Oh, you're not working today?" 

"No, it's all over." 

"Oh, that's too bad. All these workers around and no work to go around for them. Me for instance, I need a huge section of my hotel painted. Except the painters I hire cost far too much money."

"I know how to paint. I can paint your hotel for you."

"You know how to paint? I got buckets of paint and brushes you can use. I'll get you a ladder, too."

My dad started at about 11am and by 5pm he was completely finished painting. The hotel owner is impressed, "Wow! It looks good."

"You like it?"

"Yeah, you did a good job. That money you owe me for the room, forget about it. You can stay as long as you want, no charge."

"Thank you! I had no money to pay you with anyway."

"I know."


P.S. I'm moving to Poitiers (pwuh-tee-yay) in 2 days. I spent my last day home packing my bags, having dinner with the family, and watching a very pretty documentary.

That's a Yank Accent!


An extremely long overdue blog post. I've been busy, okay? So. Busy. I have never averaged so little sleep or drank so much coffee in all my life.

I've heard complaints from friends that this blog doesn't have much turbulence. Well here it is!

I was working on an ungodly exam a few weeks ago, courtesy of Dr. USA. It was literally a month long take-home exam. It involved proofs, data processing, applying theories, and then seeing why the said theories are incorrect. Hardest. Exam. Ever.

I'm currently running code (yes, on a Saturday night; turbulence isn't going to solve itself) to calculate the Reynolds stress and several correlations of three-dimensional stereo Particle Image Velocimetry data from an adverse pressure gradient turbulent boundary layer. That pretty much translates to writing lots of code and using up lots of computing power and waiting for computations to get done. A few weeks back, I was running a Direct Numerical Simulation that took a good three days to compute; using four processors. I've heard stories of really big, important simulations taking years to complete; using the strongest, fastest computers in the world.

Have you ever wondered why weather reports are so unreliable? It's because we have only the slightest idea of how turbulence works. That soy milk the hipster barista poured into your fair trade, organic, chai latte? It mixes quickly due to turbulence. Blood flowing through your veins can be modeled as flow through a pipe. Turbulent flow through a pipe. Pollutants coming out a chimney. Huge fire blasts coming out a rocket. Oil spills by BP. High-speed flow over an airplane wing. Cigarette smoke. Wind blowing through leaves. Boiling water. The atmosphere of Jupiter. My life in general. It's all turbulent!

Besides school, I've been traveling a bit. Barcelona is probably the prettiest city I have ever visited. Warm beaches, delicious food, crazy-looking architecture, and Penelope Cruz posters. Amazing.

I took a quick two-day trip to visit the schools I'll be attending next year in Poitiers. One of the schools, ENSMA, has a building that is supposed to look like a crashed spaceship. Except the campus calls is the Camembert, because it looks like a block of cheese from overhead. I hope this Camembert is better than my previous experience. Also, there's an amusement park across the street called Futuroscope. I can't wait to get to Poitiers.

I went to Amsterdam again to meet up with a friend of mine. It looks so much prettier in the summer! We went to a pub close to the infamous Red Light District. I swear, the bartender looked exactly like Artie, the Strongest Man in the World. He served us some regional alcohol called jenever. He then proceeded to disco dance to Earth, Wind, and Fire. I can now say that disco-dancing Artie served me Dutch gin in Amsterdam. Check that off the bucket list.

Finding a Different Thing to be Excited About


I went to Paris for a few days last week and then I went to Amsterdam for a day trip. I was asked which one I like better, and I don't think I have an answer. Paris is definitely more "traditionally" beautiful. It's insane! There are all these things you see in movies and read in books, and then you go to Paris and here they are; right in front of you. These amazing, legendary buildings or locations or pieces of art right in front of you and you have no idea what you ever did to warrant this kind of experience. It's pretty overwhelming. That might actually be a problem. Paris is really pretty, but it might actually be TOO pretty. I feel like I wouldn't want to live there because everyday you would just walk outside, look anywhere at anything, and it would just be far too beautiful. You need some ugly to appreciate the beautiful! I'm a big fan of water, so I was quite enamored by the canals all over Amsterdam.

I consider myself a tourist, but even I was annoyed with the tourists in Paris. By the way, a really good way to let everyone know you are not French is to wear a beret. I have never seen a single French person wearing a beret. It's like the French came up with a clever ploy to instantly identify foreigners. They came up with the idea to create this image of a beret-wearing French person, but actually no one wears them. Ever. At all. Don't wear them if you are visiting, okay?

I went to a pub called The Frog and the Rosbif. It's a French/English pub. It's fairly obvious that English speakers call the French frogs because they eat frogs. Apparently, the French have a similar term for the British; "rosbif", as in roast beef. This is probably the least offensive ethnic slur I have ever heard. Anyway, I had a beer called Dark de Triomphe. It made me so happy.

On my flight back into France after Christmas, there was a movie playing called Monte Carlo starring Selena Gomez. Now, I personally do not like Ms. Gomez. I'm sure she works hard and is generally a nice person, but the problem is her name. Her name is Selena. She is not worthy of such a name. You see, I grew up in the age of THE Selena. The one that each and every Mexican knew and loved. Her untimely demise was a huge blow to me and everyone I knew. This Justin Beiber, tweenpop, Disneycore whatever cannot and will not compare to the one true Selena. Sorry. I am not fooled by this false prophet.

I'm going back to London for St. Patty's Day. The Brits are pretty much the same as the Irish, right?

I ordered a CD from Sub Pop records (Seattle!) and it came in the mail the other day. I like hardcopies, okay? It came with a pretty photo album, so shut up piratejerk.torrent. The CD is by a duo from Toronto called Memoryhouse. For all the Seattleites, they are performing at The Crocodile on March 9, and will be live on KEXP on March 10. Highly recommend you go see them. Then tell me how they were. Here is their full new album:

Lastly is monkey news. Important stuff.

Raconte-Moi Une Histoire

Classes are crazy busy this semester. One of the reasons turbulence is so difficult is because it involves so many different disciplines; not just fluid dynamics. I'm playing in a lab, so that involves things like measurement techniques, electronics, and signals processing. Looking at the data afterwards involves statistics, advanced mathematics, and programming. None of these are my specialty. I'm definitely learning the most I've ever learned in such a short amount of time. Lucky me I enjoy what I study. It would be pretty horrible suffering like this over things I don't like.

It took my computer nine hours to go through 13 million points of data to produce this plot. (Yes I plotted in excel; my gnuplot isn't working. How about you shut up, Snobby McHater?)

I found a blog where I waste a lot of time study fluid dynamics. Here's a video I really like. Warning: insane amounts of pretty.

I was crazy jealous over the snowpocalypse that happened in Seattle. Finally! Snow in Lille! I went out and slipped around on the streets, and threw snowballs, and stayed warm in an Irish pub. It was wonderful.

I went to see Arctic Monkeys this week, and they tore it up! A thing I found odd was the start time. Back in the states, when they say a show starts at 8:00, that means the show actually starts at 9:00. Not here. When they say the show starts at 8:00 it starts at 8:00. So punctual!

I had to send a sad email the other day. A guy from Boeing emailed me about wanting me to come into his office for an interview. I had to break the poor guy's heart and tell him I wasn't actually in the country, so the chances of me showing up at his office were mighty slim. I can honestly say I've denied interviews from both Boeing and NASA. In these tough economic times, this might be a really stupid move. Oh well.

Several French girls around here have the Snooki hair thing going on. Since French fashion is popular in the US, is American fashion popular in France? If so, is "Snooki" what people think of as American fashion? God help us all.

A professor of mine used the word gigaflops the other day. For you non-nerds out there (i.e. decent, normal, non-awkward people), giga = one trillion, and flops = floating point operations per second. Gigaflops is a measure of computing speed. Except when he says gigaflops, he pronounces it "jiggaflops." I really hope he talks about power one of these days.

The Vega launch vehicle is set to have its first launch on February 13. It's a rocket developed in a joint effort by the Italian Space Agency and the European Space Agency. Vega holds a special place in my heart for several reasons. For those of you that know me in person, one of my three names is Vega. Vega just happens to be my favorite star in the sky, and my favorite Street Fighter character. At my last place of employment, my first assignment was working on the reaction control thrusters of Vega. My boss at the time thought it was the greatest thing ever: Vega working on Vega. It was pretty much destiny. It's exciting to see something I had a hand in developing take flight. (I didn't do anything all that amazing; just a bunch of functional requirements. But still! Go Vega!)

Lastly is a story. A story about a man. This man just happens to be a legend in the world of turbulence, and a professor of mine. Let's call him Dr. USA.

One day Dr. USA was teaching something out of a book. He said something that one of his students questioned. The student asked how Dr. USA knows an assumption that was made was true. Dr. USA responds by saying that he doesn't actually know it's true, so they should try and prove it. He cleans up the whiteboard to start fresh from scratch. He takes up a good portion of the class trying to prove this thing, but he kept running into problems. Eventually it's the end of class and the student has lost interest, but not Dr. USA. He tries and tries to prove this thing, but he can't seem to get it. He even reaches out to his colleagues and asks them if they have ever tried to proving this. It turns out none of them have.

Two months of working on this problem pass, and finally Dr. USA decides that if he can't prove it, then it must be false. This is a big deal, because it's an idea that has been accepted as true in the field for decades. Questioning something like this is almost considered blasphemy to fluid dynamicists. One day, Dr. USA is giving a talk about how this popular idea in this book is wrong. Sitting in the front row, is a young, bright-eyed student with the book in hand. He asks Dr. USA something along the lines of: How could you say this is wrong? It's been around for years! No one has ever questioned it! Experiments support this idea! Finally he asks "Okay, if this is wrong, then how would you fix it?" Dr. USA responds, "You want me to fix your book?" "Yes I do." Dr. USA calmly walks down to the student, takes his book, opens it to Chapter 4, and starts ripping out pages. The entire auditorium bursts out in a frenzy. Oh by the way, the book in question is written by Dr. USA's advisor; the guy who gave him his PhD. The advisor wasn't actually there but word travels fast, especially with something like this.

After this happened, Dr. USA and his advisor don't speak for ~10 years. One day, they finally see each other at a conference. The two meet and greet and catch up on old times. Eventually, the advisor says to Dr. USA, "You know, now whenever I teach Chapter 4, I use your method."

Pretty much the baddest badass I've ever met.

Living Two Lives is Exhausting

Bonne Année!

I went to London! It was bloody spectacular! I remember the first night I got into London, I went walking around at night. As I was walking, I just started smiling. Something about London...the smell in the air? The look of the old architecture? The funny accents that are heard? I have no idea, but I liked it. I walked on bridges that are older than my country, I spoke with kind English gentlemen, I climbed to the top of a pretty church, and I rode the slowest moving ferris wheel I've ever ridden (with the greatest view also)! I definitely need to go back.

I went back to Seattle for Christmas. I didn't realize how much I missed Seattle until I was actually back there. My first morning back, I decided to go out for breakfast. I step outside, and there is the tiniest, quietest drizzle. On the way to the breakfast place I see a farmer's market being set up. When I get in, I am instantly greeted by a hipster waitress. There is Band of Horses playing on the radio. I sit down and order myself a cup of Stumptown coffee. There is a Chinese family (not too FOB-ish!) having breakfast at the far booth, and a gay biker couple sitting to my left. I look outside the window and I see people outside walking their dogs. All things Seattle, all things wonderful. I decide right then and there: I belong here. Sure, I'm off studying in France for a while and traveling around; but there is no place like Seattle.

When I first came to France, I was a little freaked out because it felt like I was just this selfish guy going off doing whatever I want with no regard for anyone. I was just leaving everything and everyone behind. Except since I came back, I realized that I didn't actually leave anything behind. All the people and places I knew and loved are still there. A few things changed a bit and that's okay, but they're all pretty much the same. Even visiting my hometown (which shall remain nameless) was nice. So to all my friends and family: thank you for putting up with this selfish little adventure of mine. Thanks for being there when I come back. Seriously.

My New Year's resolution last year was to take more risks and to make more mistakes (partly inspired by a good friend). I think I've lived up to it pretty well and learned a lot from it. So here's to 2012! May your year be as fun/beautiful/terrifying/random/memorable/enlightening as I hope mine is!
