Art + Multimedia

In December we visited a lecture about interaction between arts and sciences, namely between (primarily) visual arts and (again, primarily) multimedia studies (Russian page). The lecture was given by Asya Ablogina, who turned out to be a nice girl. Although she lacked any technical background, she was doing well. Surprisingly, there is a lot of artwork that exploits technical support in a witty manner, which I was unaware of, so the lousy stuff exhibited in the Moscow Museum of Modern Art is not everything one can do in this field!

The most interesting part was Asya's exposition of some masterpieces. Most of them were presented during 2009 Science as Suspense exhibit in Moscow (Russian). Nicolas Reeves is a famous Canadian architect, also known for his work on modelling biological systems. He used the output of biologically-inspired computer algorithms (such as genetic algorithms) to draw pictures. In Moscow he presented a project called Marching Floating Cubes: massive but light cubes float in the air. Their movements are controlled by tiny fans, although any little gust of wind can affect the movement. Each cube is equipped with an on-board computer, which helps to avoid collisions. The implemented algorithms are simple but stochastic, hence the behaviour is unpredictable. They are said to move like animal creatures. Here is the video:

A similar project was developed by Paul Granjon. He also tries to gift robots with animal behaviour. In the video below, robots are sexed, i.e. they are able to locate robots of the opposite sex and eventually end up in coitus. Another Paul's robot (the Smartbot, photo) creeps over the restricted space and always grumbles (just like Marvin!). I also enjoy the way Paul speaks:

The real idol in the sci-art community is Stelarc (see also his homepage, although it takes balls to get through the welcome page :). His talent is recognized by both scientists and artists (it is enough to mention he's an Honorary Professor of Arts and Robotics at Carnegie Mellon). He's best known for his experiments on his own body. For example, during a performance he allowed to control his body remotely over the Internet by muscle stimulation. Probably his favourite project is Prosthetic Head, which is in fact a 3D model of his own head. The head is learned from Stelarc's behaviour and speech, so it is able to communicate with people using colloquial information as well as non-verbal cues. It is interesting to try it in practice, but here is just a non-interactive demo video:

Stelarc is probably the only person on Earth who has three ears. In 2007 surgeons implanted an ear into his arm! It is not functioning now (just a piece of skin), but he plans to install an audio receiver into the ear and broadcast everything he hears over the Internet. I definitely recommend to look through his projects, there are decent ones.

Asya also presented her own works. She focus on different photographic techniques such as overexposure. Here are photos from her project Canvas of the Road compiled in a video. There is a play of words in Russian: the single word for canvas and road surface. On these photos car traces look like painter's strokes:

Another Asya's project is a short film series called Habitat. She showed only one episode with the title Habitat: MSU Main Building. The film was about a girl who is a PhD student in Moscow State University and described her place: a standard 8 sq.m. dorm room. The narrative was full of expressive epithets and metaphors about that awful room: the girl felt like in a cage, she also didn't like shared bathroom, etc. It's funny, because I live in a similar PhD student single room, and I'm quite happy with it, since I've been living 5 years in a shared room before. :)

The second lecturer, Vladimir Vishnyakov, presented his project called The Museum of Revived Photography. He used the photos of the XIX century to create image-based animation. The idea is technically simple: first segment people from the background, then use inpainting techniques to restore the background behind them, and animate the movements, but Vladimir referred to a programmer he works with as a real genius. In fact, all the stuff I post here varies from easy to moderately complex (except of Stelarc's projects), so you can do something similar too. The main problem is to come up with the concept. Come on then! ;)

Blinded Wheat Challenge

Self-experimentation can be an effective way to improve one's health*. One of the problems with diet self-experimentation is that it's difficult to know which changes are the direct result of eating a food, and which are the result of preconceived ideas about a food. For example, are you more likely to notice the fact that you're grumpy after drinking milk if you think milk makes people grumpy? Maybe you're grumpy every other day regardless of diet? Placebo effects and conscious/unconscious bias can lead us to erroneous conclusions.

The beauty of the scientific method is that it offers us effective tools to minimize this kind of bias. This is probably its main advantage over more subjective forms of inquiry**. One of the most effective tools in the scientific method's toolbox is a control. This is a measurement that's used to establish a baseline for comparison with the intervention, which is what you're interested in. Without a control measurement, the intervention measurement is typically meaningless. For example, if we give 100 people pills that cure belly button lint, we have to give a different group placebo (sugar) pills. Only the comparison between drug and placebo groups can tell us if the drug worked, because maybe the changing seasons, regular doctor's visits, or having your belly button examined once a week affects the likelihood of lint.

Another tool is called blinding. This is where the patient, and often the doctor and investigators, don't know which pills are placebo and which are drug. This minimizes bias on the part of the patient, and sometimes the doctor and investigators. If the patient knew he were receiving drug rather than placebo, that could influence the outcome. Likewise, investigators who aren't blinded while they're collecting data can unconsciously (or consciously) influence it.

Back to diet. I want to know if I react to wheat. I've been gluten-free for about a month. But if I eat a slice of bread, how can I be sure I'm not experiencing symptoms because I think I should? How about blinding and a non-gluten control?

Procedure for a Blinded Wheat Challenge

1. Find a friend who can help you.

2. Buy a loaf of wheat bread and a loaf of gluten-free bread.

3. Have your friend choose one of the loaves without telling you which he/she chose.

4. Have your friend take 1-3 slices, blend them with water in a blender until smooth. This is to eliminate differences in consistency that could allow you to determine what you're eating. Don't watch your friend do this-- you might recognize the loaf.

5. Pinch your nose and drink the "bread smoothie" (yum!). This is so that you can't identify the bread by taste. Rinse your mouth with water before releasing your nose. Record how you feel in the next few hours and days.

6. Wait a week. This is called a "washout period". Repeat the experiment with the second loaf, attempting to keep everything else about the experiment as similar as possible.

7. Compare how you felt each time. Have your friend "unblind" you by telling you which bread you ate on each day. If you experienced symptoms during the wheat challenge but not the control challenge, you may be sensitive to wheat.

If you want to take this to the next level of scientific rigor, repeat the procedure several times to see if the result is consistent. The larger the effect, the fewer times you need to repeat it to be confident in the result.


* Although it can also be disastrous. People who get into the most trouble are "extreme thinkers" who have a tendency to take an idea too far, e.g., avoid all animal foods, avoid all carbohydrate, avoid all fat, run two marathons a week, etc.

** More subjective forms of inquiry have their own advantages.

Fashion Tips, Part II

As promised, here are some specific professional dress tips for women. I am in no way a fashionista - I am a computer scientist - but I will pass along things that have worked for me. I should also note that I am all about low-maintenance everything - clothes, hair, shoes, etc. I want to optimize sleeping, research, and goofing off - not waking up three hours early to put on makeup and straighten my hair. (That'll be the day!). And I hate ironing.

The ultimate goal for professional dress for women (of all levels - from casual -> business casual -> formal attire) is to look classy without looking trashy. Most modern clothing designers make this damn near impossible, as they seem to think all we women ever want to do is to pick up guys at bars.

What's worked for me is to buy a few nice, key articles of clothing that are robust and hold up to being washed frequently. If I find an article of clothing that fits exceptionally well and looks well-made, I sometimes will buy several. (Because you can bet anything if you go back in a few months it won't be there!). Sometimes you spend a little more to get something well made, but it (usually) lasts longer than something cheapy, so it's worth it.

I've interleaved a few tips about dressing down outfits, since a few of you asked.

Stores

There are a few clothing stores that I always manage to find something at, and if you manage to get sales you can often swing some wonderful deals. These stores include:

- Ann Taylor  / Loft
- Chico
- JC Penny
- Sears
- Macy's
- Kohl's
- *sometimes* : Banana Republic / Gap / NY&Company/H&M/Target. Sometimes clothing from these places falls apart after two washes, so it's not always worth it, but sometimes you get lucky and have a great find.

Pants

I like to buy lined pants, because they can make one look professional without looking trashy or dowdy. Typically my favorite place to find these have been Ann Taylor.

In general my rule of thumb for pants is if another person can tell when you're flexing your gluteus maximus, they're probably too tight for a professional context.

Sometimes you need to spend a bit of money to get pants altered. If the pants are well-made and will last you a few years, this is money well-spent. I have two pairs of pants I wear both as part of a suit and also solo for less dressy occasions. I paid more to have them altered than I did the pants, but they fit exceptionally well and look good, so it was worth it.

Shirts

As I said, I'm all about low maintenance and comfortable, so most of the shirts I like to wear are made of fabrics that don't wrinkle, like lycra, and cotton knits. Chico sells some great, thick lycra shirts that are nice and can help conceal pudge if you have any. Their sizes run big, though, so if you have a more petite figure you may need to take the shirts in a bit.

I occasionally wear button-down shirts, but in my experience they are more trouble than they're worth, because you inevitably have to iron them. Some friends had good luck finding iron-free shirts at places like Brooks Brothers, but when I went there I found their shirts looked ridiculous on me. They felt like they were designed for men.

Sweaters are a great way to dress down fancier pants, if you don't want to look too formal but don't want to wear jeans. I like cotton turtleneck sweaters, or sometimes V-neck sweaters with a tank-top / cami on underneath them. Gap and H&M have served me well here - I've purchased a few thick cotton sweaters there that have lasted me for years.

Just like pants, it's important to get shirts that fit well, that are not too tight and not too low-cut. I have owned a few shirts over the years that were too tight for professional contexts, so I fixed them with a cardigan, jacket, or a pashmina.

Skirts and Dresses

I have no tips about skirts and dresses, as professional ones always seem to look ridiculous on me. And more importantly, panty hose and tights are far too high maintenance. One run and you're stressing out over nylons instead of, say, your conference talk. Not fun.

Jackets

Blazers are a great way to dress up jeans, so you can find a happy medium. I really like darker colors, such as black and dark brown. Definitely solids, though a light pinstripe is ok I suppose. I think corduroy blazers are great for men and women, regardless of whether they are in style or not - they just look nice.

Cardigans / open sweaters are a nice way to dress down fancier pants if you're worried they look to dressy. If you get one that is fitted, it will look professional without looking frumpy. (Here are some examples). Though I'll tell you, at my last job I always wore big frumpy sweaters because some of those machine rooms were cold!

Shoes

The most important thing about shoes is that you are comfortable. Again, shoe designers are seriously out to get us. I can't tell you how many shoe stores I visited over the holidays with my mother-in-law, and we both basically decided the shoe designers are Satan.

Shoe designers are satanic.

A few brands that maybe/sort of / sometimes feel comfortable are:  The Walking Company, Aerosole, Naturalizer. Sometimes you can find comfortable casual-dressy shoes at L.L. Bean, REI, and EMS. People that design shoes for hikers often have enough clue to design comfortable shoes that can be worn by white-collar office-warriors.

The only other rule for professional shoes is don't wear: furry boots, hiking boots, open-toed boots, flip-flops, or sneakers. Otherwise wear whatever you like.

Bags

Try to avoid using a backpack if at all possible. I'm aware that it's better for your back, especially if you are lugging around many things from place to place (laptop, papers, books, etc). Instead, there are nice wheely professional bags for women you can get. Sometimes people look at you funny wheeling something across an office building or campus, but you can just smile and say, "Bad back", and they'll leave you alone.

But if the wheely bag isn't appropriate for your context and you want to save your back (can't blame you), try to get a classy looking backpack. For example, select a bag from here. Several of these are perfectly reasonable to use in professional contexts.

Otherwise, if your travel gear is lightweight, really any shoulder bag will do. Just keep it simple and low-key. No bling.

Jewelery


Really wear whatever you like, just be sure it is tasteful and nondescript. Also be aware than anything with any sort of symbol or emblem on it will likely spurn discussion, which may or may not be a good thing.

Coats

I think wool coats with straight lines and nothing hanging off them are the most professional looking. I knew someone who always wore a fur coat to work and it always looked very strange to me. Sportsy jackets tend to look odd if you have dress pants on. (Or at least they do to me).

And that's all she wrote. I will try to do a post for the men sometime within the next few weeks.

kitchen painting

my kitchen is definitely a work in progress.  the previous owners had lots of green accents throughout the house and so the wall color made perfect sense.  however, with our stuff moved in, it kind of sticks out like a sore thumb.  i have until friday to make a decision and i keep flip flopping.  i can't decide whether to paint the cabinets white or go a greige (a light grey/ green color).  here are some of the kitchens that are inspiring me.  and i threw in a pic of our current kitchen for giggles...don't you love how i styled it!!  i mean, are those seriously bunny ears on the counter...see the kind of disaster i am living in!!??

speaking of kitchen, last night i had my inlaws over for supper (they live about 5 minutes away from us so it will probably be a weekly occurrence).  my parents had cooked a pizza the other weekend for me that i couldn't get out of my head and i was dying to try to make it....it's the strangest combination but divine- potato and leek pizza from the pioneer woman.  you have to try it- seriously!  luckily my inlaws know that i am a walking disaster case so when i dumped all the bacon on the floor that was suppose to go on the pizza, they just laughed and said we could always get take out!  luckily, i had more bacon to spare in the fridge and the pizza turned out good...at least everyone humored me and said that :)
