Vacuum Tube Assignment

-
The vacuum tube was invented by Sir John Ambrose Fleming and was patented in 1905. The vacuum tube worked by placing an extra electrode inside of an incandescent light bulb. When the filament of the bulb was heated white-hot, electrons were boiled off into the vacuum inside the bulb. If the extra electrode is made more positive than the hot filament, a direct current flows through the vacuum. The current flows from the filament to the electrode, converting AC signals to DC.
The vacuum tube (or vacuum diode) is considered the beginning of electronics and was used in radio receivers and radar for over 50 years. The invention of the vacuum tube allowed for innovations such as television, long distance phone calls, and the first electronic digital computers. Today, vacuum tubes have been replaced with transistors, but for over half a century, the vacuum tubes were a crucial aspect of the most advanced technology.

Flipbook Project

-
My flipbook is based on the novel 1984 by George Orwell. This novel is a dystopian future novel (one of the original dystopian future novels) centered around a middle aged man named Winston who falls in love with a younger woman who is a member of the Party. They carry out a secret relationship, trying to hide it from Big Brother, until they get caught by members of the Party. Much of the imagery in the story is what I chose to illustrate in this flipbook. The glass paperweight which represents a secret paradise to Winston, images of Big Brother watching over the people walking through the street in their blue jumpsuits, the picture of the Church hanging in the secret room in the shop that conceals the telescreen that watches Winston and Julia, and of course the slogan of the Party: War is Peace, Freedom is Slavery, Ignorance is Strength. While drawing the images for this flipbook, it was really difficult to gauge the speed of frames and how that would look in video. As a result o

Marina Abramovic & Pierre Huyghe Response

-
The way these two approach art is very interesting and an example of why modern art takes such an indirect approach to expression. Huyghe particularly, says that his art is not meant to be an absolute. It's meant to do more than just stoke the fires, it's meant to create deep realities for one to dive into. He explains that his intention is not to create a singular, clear story, but instead to "build a kind of mythology" and an emotional aura that consumes a viewer. When he creates, he builds the world in his mind and then creates from that mental space. In that way, his art benefits because viewers are better able to immerse themselves in the work. In the case of Abramovic, she similarly approaches her work unconventionally to elevate the quality of her work. She sees her work as using the human body as a medium. Most might say her medium is photography, but since Abramovic plays with the artistry of the human body, her artwork takes on an interesting form as if it w

Raul Cuero Interview Response

-
Dr. Raul Cuero's interview about creativity and the importance of creativity presents interesting inquiries into the application of creativity in our own lives. How can we grow our creativity early in our childhood, as well as deep into our adulthood? An important point brought up by Dr. Cuero is the importance of inductive ideas, answers, and solutions rather than deductive. As in, creative methods come from inside us. They come from our ability to problem solve and find new methods to do things rather than the typical or commonplace way of doing it. Every method of doing everything had to have originated somewhere. These ideas originated from someone that was inquisitive and creative. Without creativity, our society would remain stagnant for all of time. The next time you are proposed with a problem, don't look the answer on Google or find the instruction manual. Be creative. Work the problem to find a perhaps more efficient or enjoyable way to do it. Talk to others to let yo
