Event 2 - Physics Lectures

Last Thursday, I was fortunate enough to attend the Art|Sci rendezvous hosted at CNSI. The rendezvous was to help artists and scientists exchange ideas. This time, I was really interested by the talks given by two physicists.

Video 1: Dr. Jofre's little motor
Ana Jofre gave a quick and brief introduction to magnetism. Ana got her Ph. D. in physics at U Toronto but she became an artist after that. Her work focused on the intersection of physics and art like cyborgs. To be honest, I was pretty familiar with the magnetism concepts she introduced because I learned that from Physics 1B as a south campus student. However, her live experiment pushed the talk to climax. She hand-made several sets of magnetic motors using batteries, magnets and copper wires. She demonstrated and passed the equipment to everyone. Everyone was fascinated by the simple yet elegant "toy". I was also excited and even shot a video of it.

Next, Professor Walter Gekelman talked about plasma and his lab. Plasma was also named "the fourth state of matter". As a plasma, the electrons in the matter were able to move freely and create wonderful visual effect. During the talk, Professor Vesna showed a proposal in which a plasma container was put above a fish tank. The design was inspired by Professor Gekelman's interest in golden fish.

Professor Gekelman also talked about the applications of plasma research. One of them was to predict the behavior of solar wind. Solar wind was plasma ejected from the surface the sun which could disable the telecommunication infrastructure on Earth. The study of such behavior could save us from the loss from the shutdown of such infrastructure.

One more thing! The wine was really great. DESMA talks were the only events reaching such a high standard in terms of the food and drink provided. Yay!

Week 9 - Art + Space

Exploring the deep and remote space has long been the dream of human beings. I am not an exception. My curiosity on the universe started even when I was a child gazing at the sky at night. The blinking stars were as if a road sign welcoming me to explore. Deep into the night, my imagination was always able to fly high to the space even though my pathetic body is jailed on the ground.
Figure 1: The Doraemon movie on space exploration
At my early age, I was keen on watching a Japanese Anime called Doraemon. The anime series were a porn for juvenile tech lovers. In every episode, Doraemon, one of the protagonists coming from the 22nd century, took some high-tech machine from his "four-dimension" pocket which had unlimited capacity and helped his friend out of some embarrassing scenario. In 1981, they made a Doraemon anime film called Doraemon: The Records of Nobita, Spaceblazer. In the context of the film, earth beings like the protagonists were like supermen on Koya Koya Planet, which was connected to below Nobita's bed via a wormhole. The film told a story of how the "supermen" became friends with a group of natives on Koya Koya Planet and fought against a huge mineral monopolist. The film showed some spatial concepts like wormholes, teleportation and loss of gravity. As a young space lover, doubtlessly I was fascinated by the film.
Figure 2: Poster of the movie Interstellar
A more recent movie telling a time-space traveling story I liked was Interstellar. The selling point of this movie included not only the stunning graphics, but also the meticulous simulation of the "real" image of black holes and other scenarios. Many of the scenarios were actually supported by the work of top physicists. It was a satisfying visual banquet.
Figure 3: The cover of The Three Body Problem
Recently, a science fiction by a Chinese writer attracted many international readers' attention. It also won the 2015 Hugo Award for Best Novel. It was the title – The Three Body Problem. The book described how human beings interacted with the residents of the Three Body Galaxy, which was constantly threatened by its unstable state and finally destroyed due to the revelation of the coordinate. The most shining point of the book was the theory named Cosmic Sociology, describing the relationship among different civilizations under the situation of lacking of inter-communication.

I'm really glad to see the course ends with a chapter on space. The course may end, but the spirit of exploration exists forever.

Week 8 - Art + NanoTech

Although nanotechnology is considered a new thing for most of the people just like many other microscopic technologies such as genetic technology, it has been the corner stone of my field for several decades. The whole computer science is possible because of the development of nanotechnology; the nano-scales transistors which make up the CPUs are deep at the core of every computer.
Figure 1: The Chip Butterfly from Intel

Intel, as the largest CPU designer and manufacturer in the world, has released many artworks like advertisements and posters. My favorite one is the "Chip Butterfly". The most remarkable feature of this work is the pattern of nano-scale integrated circuits on the wings of the butterfly. It symbolizes the interaction of technology, art and the nature. The flying butterfly also means the chip unleashes the potential of the user. 
Figure 2: Drug delivery robots
Nanotechnology also has potential in the field of medicine. Like the "3D Box" what Dr. Gimzewski introduced in the lecture video, there's a lot of space for creativity in this context. In my midterm proposal, I mentioned the possibility to build a wireless robot system to deliver drugs precisely in human bodies.
Figure 3: Patterns drawn using STM
The invention of Scanning Tunnel Microscope enables artists to draw on another canvas. With STM, operating on single atom is now possible. Figure 3 lists some atom drawings. The middle piece in the figure is the Chinese characters for "atom".

Week 7 - Art + NeuroSci

Neuroscience is about people's mind, memory and imagination. DESMA 9 was not the place where I first got experience with neuroscience topics. One year ago, in the summer vacation, I was reading a book called Incognito by David Eagleman. In the book, Eagleman models the brain as a pair of "rivals". On one hand, there exists a fast response system that will be triggered in the first place, and often unconsciously. The author describes an experiment to illustrate how this system works. The experimenter asked a group of people to describe the process of changing lanes in their words. None of them did it correctly because changing lanes was a process "burned like a circuit into the brain". On the other hand, something like doing hard mathematical problems is handled by a proactive thinking system; one has to go through the reasoning process to draw a conclusion.

Figure 1: The book Incognito
Besides literature, neuroscience ideas are also borrowed by computer scientists. Neural networks is  an advanced technique in the subfield of artificial intelligence. Like how real neuro-systems build responses from experiences, neural networks are trained by real data to simulate any function which accepts a set of parameters as input and returns a value as output. The program named AlphaGo which defeated Go world champion Lee Sedol used neural networks as part of its reasoning system.
Figure 2: Neural networks utilized by AlphaGo
Many visual art forms also get ideas from neuroscience. My favorite is the film Inception, which depicts a world where people can be trapped in their dreams. In this situation, it is interesting to see how people invent secret methods to help them distinguish real world from dream worlds.
Figure 3: The poster of movie Inception
The various application of neuroscience is referred to as "neuroculture" by Giovanni Frazzetto and Suzanne Anker. They believe the transformation from a science to a culture has made neuroscience more friendly to the society. As a fan of neuroscience, I'm also happy to see the chemistry happening between the science and the society.

Week 6 - Art + BioTech

Biotechnology, as Professor Vesna introduced in the video for this week, is full of controversy and undefined things. People are curious about biotechnology, but also are afraid of it, because they know only a small corner of whole map. Biotechnology remains unknown to most of the public and this mysterious characteristic amplifies the concern of people about its research and application. Artistic expressions of biotechnology, as one of the applications of it, induced both inspiration and criticism.

Art work normally means creation, which is generally accepted as a good thing except under this special context – biotechnology. Public opinions have not yet decided whether "life" should be proprietary to some higher beings, possibly the God. Many people believe that human beings should not modify life forms, viewing the modification as profanity. Others are concerned about potential biological disaster without proper control and regulation of the usage of biotechnology. Imagine a plant which could transmit virus via its fruit. How frightening would that be? It may be a extreme example, but the core problem – safety – remains unchanged. For example, transgenesis technology allows farmers to grow crops that are more productive and more resistant to crop diseases. However, the public are questioning if genetically modified food could cause human diseases like cancer. The public medias are also deliberately informing people this kind of ideas by using cartoons or exaggerated pictures, like those shown below.

Figure 1: Negative propaganda of GM tomatoes
Figure 2: Another negative propaganda
The existence of "outlaws" makes the regulation harder to implement. From an essay called "Meanings of Participation: Outlaw Biology?", the will of participation in biotechnology gives birth to homelabs and "rogue biologists". In 2004, Art professor Steve Kurtz was arrested because FBI found biological equipment at his home after he reported the death of his wife. Although I personally believe professor Kurtz knew what he's doing, we are not assured that every artist or owner of homelabs know what they are doing. Even if they know, are they prepared for the potential outcomes of the experiment?
Figure 3: Scientists operating child's gene in Gundam SEED
The Japanese cartoon Mobile Suit Gundam SEED depicts a world in which human beings are divided into two groups – genetically unmodified people called "Naturals" and genetically modified people called "Coordinators". In the cartoon, the Coordinators own superior abilities to Naturals because of their enhanced genes. This gap between the two groups generate sharp social conflicts. Naturals are jealous of Coordinators' ability and expel them from the Earth. After that, Naturals even nuked Coordinators' colonial satellite. Under this situation, war was born. This cartoon warns us to be cautious about the regulation of biological technologies.

Event 1 - Toni Dove Lecture

Two weeks ago, I went to the EDA room of Broad Art Center in UCLA for a lecture given by Toni Dove. Dove was regarded as a precursor in the field of interactive art. She was especially interested in  human computer interaction, also a hot topic in my field – Computer Science. Not surprisingly, she talked about the experience she cooperated with a software engineer in her studio in New York City. She introduced to us the process through which her artistic ideas were realized – designing, modeling, and iterating.

I was especially interested in two projects she demonstrated. She showed a scene with a dancer on the screen embracing a transparent ball. She was able to use gestures to control the motion of the dancer. She also showed us the mechanism – a gesture sampling and analysis software. It was a successful project about human interacting with computers via something not keyboard and mouse.

Artificial Changelings was the other project. A view was able to stand in front of a screen. Depending on the different zones s/he stood in, the image changed its topic. Different scenarios could also decode the motion and gestures in various ways. For example, in the "inside the character's head" mode, the viewer's gestures changed the character's facial expression.

These two projects are interesting to me because HCI is a hot topic in Computer Science. The very last revolution in HCI has made Apple, once struggling with their computer sales, rise again with their stunning iPhones. The innovative way of interaction – touching – at that time, has caught users' will of purchase immediately. Therefore, I believe the next revolution in human computer interaction will also unleash a dazzling new style of life.
