Living My Life To The Tune of Toto
So first off, I know this post is long overdue. Over the past couple months my life has been a fire storm of events, emotional ups and downs, and other such things. So with all that said, how about I give you and update as to what I have been up to.
First and foremost, the biggest part of my life has involved going to Africa twice this summer. The first time I went was for a scholarship program. A group of 6 students and two professors traveled to Tanzania (Specifically the island of Zanzibar) to film a documentary on an NGO (Non-Government-Organization) doing unique works to charity. Now you are probably asking: "Hey Nonberg, where are the sweet pictures of the pirate flag?) Well, to that I would say, it was impossible to take pictures with the pirate flag considering the airline lost my suitcase with the flag in it. I did not get the flag back until the airport. At that time my camera was out of batteries. I could write volumes on what happened in Africa, but hopefully I'll be able to share my documentary with all of you when its done in the next month or so.
My second trip to Africa was for a family vacation. For my parent's 60th birthday, they decided to give each other the gift of a safari (their life's dream forever.) I saw some animals I never thought I would ever get to see in person. If you guys are interested in seeing some of the pictures I took check out this link:

So that's my life in a nutshell over the past couple of months. Right now I am currently starting my second year at school and am now the new assistant coach here on the team. I can't wait to see everyone in a couple of weeks.

I'm in Bolivia!
Hey you all so I finally made it down to Bolivia. I guess I really never explained why I made the trip down to South America and some of you probably didn’t even know I was down here to begin with. Well I was offered a job to work for an alumn managing some stores he owns in Bolivia. I figured this was a once in a lifetime opportunity so I accepted. The job in itself is only ok. I work in a bookstore here in La Paz. We have a decent selection of used books that we sell at reasonable prices and we also sell different camping and hiking supplies like backpacks, tents, sleeping bags, pretty much anything you would need to travel or hike. To be honest it almost feels like I’m hustling out on the streets since I’m constantly bargaining for prices with our distributors and trying to get people to buy from us. Our sales have also dropped in the last few months since other stores that sell the same stuff have opened up. La Paz is also not the most attractive city, so I was amazed to see that the majority of our clients are tourist. From far away the city looks really cool since it’s surrounded by mountains, but once you get close it’s pretty dirty and poorly developed. Other parts of Bolivia are supposed to be really pretty so I may travel out some once I get my first paycheck.
I’m staying in an apartment that my boss has rented out for us and has subsidized part of the cost. My roommate is a Carleton grad from ‘09 who works with me and has been in South America for a while. He is pretty familiar with the city and the store so he has pretty much been showing me around until I get the hang of everything. We also went out with a group of his friends last weekend and I proceeded to get really drunk. To make a long story short altitude makes you get drunk faster and I blacked out got lost in La Paz, lost my phone, that I had just bought a few days ago, and got home at nine in the morning to find out that my boss had spent most of the morning trying to find me to help him get stuff from the market, so much for first impressions.
I plan on staying here in South America for a few months unless I get offered another job but I’m not holding my breath on that. I’ll most likely end up returning in May and start applying for grad schools and looking for jobs. This means I’ll miss the alumni meet, which kinda blows, but I might pass by Carleton in the spring. Also what is the deal with the Brocation? I really don’t mind if you guys plan it while I’m out here but lets get the ball rolling. Alright well I hope all is well in the states have fun at the alumni meet and will keep everyone posted on my trip.

Anyway, I really just wanted to use this as an opportunity to post on my favorite world-revolutionary product that wasn't. And to post a bunch of pictures of people looking ridiculous on Segways:

Senior Year WTF?
Sunday, September 19, 2010
Hey guys
The prelim exam is a two day test, covering everything that I should have learned in 4 years as an undergrad and in my first year as a graduate student in physics. So: Electricity and Magnetism, Special Relativity, Classical Mechanics, Quantum Mechanics, Statistical Mechanics, oh, and lots of math. All of the Ph.D. candidates have to pass the preliminary to continue on in the program, we generally get two shots in case we don't pass the first time. So about the last month of the summer I spent trying to be prepared for the exam. More than once during the process I was struck with the impression that I had learned too much, that the sum of human knowledge was too great, and that maybe solipsism would be a more tractable philosophy.
My New Theory of Everything:

Back to the point. The prelim exam kind of sucks, and it certainly isn't the best way to test our propensity in physics, but I guess I made some connections while studying. And--yes--I did pass, so that's what matters at this point.
So the day after the prelim was over classes started--as a grad student, I do miss having long breaks of not having to do anything school related. This term I'm taking Gravitation (General Relativity) which I think will be a fun course.
I have a light course-load because I've found a professor who actually has some extra grant money lying around and is willing to give me some of it to help him do his research. This part of grad school, I've found, is not always as easy as it sounds. Anyway, the professor that I'm working for has been researching granular materials, particularly their critical point where they transition between being liquid-like and being solid-like.
Starting out with a research group can be slow, and my first simulation seems to be... inconclusive at this point. But I can tell you about one aspect of my work that has been interesting. That has been learning how to do general-purpose computing on graphics processing units (GPGPU). So what does this mean? A GPU is the primary component of the graphics card in your computer which carries out many of the computations necessary for displaying graphics on your screen. Compare this to the CPU (C for Central) which carries out all of the other instructions from the programs running on your computer. What you may not know about your CPU is that while your task manager or activity monitor tells you that you are running many processes, each of which are in turn running several threads (a single set of instructions) all at the same time, your CPU can only actually handle one set of instructions at a time. So it actually cycles through all of the threads, but does so so quickly that to you, your iTunes music plays simultaneously while you type your paper and search for distractions on the internet. (Many computers now have dual, quad, or multi-core processors where each core actually can run threads simultaneously with each other). What makes a GPU special is that it has hundreds of cores and can run at least that many threads at once. This was originally useful for computer graphics, especially in video games, where, for example, you might have some 3D object which you could represent with a large array of data. Then in order to figure out how to display the object on the screen, how to light it, etc., you need to perform some calculations on the entire array of data. While GPU's generally can't do a single calculation as fast as a CPU can, their ability to do many calculations in parallel can make them much faster at this type of calculation. So these types of calculations are offloaded onto the GPU greatly increasing the overall speed of the program and allowing programmers to make more detailed graphics.
Of course, computers are being used to handle very large sets of data for many more reasons today, including research. So it is only natural that researchers and others would want to get in on the power of graphics processors. One company that has made that possible is NVIDIA with their CUDA architecture, which is what I've been learning to use. They created a library extension to the commonly used C++ programming language that can be used with any of their graphics cards in production today. Learning to write programs in parallel has been interesting and difficult at times. I have to worry about things like two threads accessing the same memory which can make algorithms to do simple things much more complicated. But I'm finally getting the hang of it and pretty soon we'll see what kind of a speedup it can have on our programs. Anyway, I think it's kind of interesting stuff and it's a pretty safe bet that computers and computer programs will increasingly rely on massively parallel processors like GPU's in the future.
Finally, I realize that got kind of long and I don't know if it's really interesting to everyone else, so I'll leave you with the youtube video I've been enjoying this weekend:
Someone needs to mash this up into a debate between Phil Davidson and Basilmarceaux.com. I smell youtube gold! Get on that internet.
