Merritt, R. (2010, July). Apple says iPhone4 antenna is state of the art
http://www.eetimes.com/electronics-news/4204654/Apple-on-iPhone-4-antenna-
Summary
In this article, it says that the antenna of iPhone4 is different from other smart phones' antennas; the iPhone4 has a perfect antenna. The antenna brings a good signal to the iPhone4; the signal is better than those of other smart phones and previous models. Apple has not received many complains about the antenna signal.
Reaction
An antenna is important to a cell phone. The antenna affects the quality of communication. The antenna is made smaller and smaller, but when a company makes a small antenna and still considers its quality, that will be a challenge. In order to get a strong signal, the antenna is always long and big, but today the technology emphasizes ingenious designs; that is a trend. The electric products have become smaller and smaller. If a product is small and includes several functions like a computer, the product will be popular, such as iPhone4; the iPhone4 is not only a cell phone, but also a portable computer. In my opinion, this article is about the antenna, but I think the real meaning is to imply the trend of technology.

LePedus, M (2006, March). Solar-cell fab capacity rising
http://www.eetimes.com/electronics-news/4058981/Solar-cell-fab-capacity-rising
Summary
This article describes the development of solar cell. Many companies are studying and competing for how to increase the efficiency in solar cells. In order to save the cost, the solar cells are becoming smaller and smaller. This can not bring huge profits but also alleviate the risk of decreasing resources.
Reaction
I have taken the class which is about solar cells in university; the class talks about the theory and process of solar cells. A solar cell uses a silicon plate to be its base, then is coated with several metals and semiconductors, and that makes it absorb the sunlight; it will produce electric current, the translation rate is about 15%; to increase the efficiency is the most important goal.
The risk of resources has been becoming an important issue. In order to save resources, the research of alternative energy has become popular; one kind of alternative energy is the solar cell. The principle is to combine different dielectric materials which make the solar cell absorb lights and produce electricity. Although the research is proceeding, I think it will be a trend to become a new energy.

Art Video
I saw the video : http://tinyurl.com/2dthj5l Impressionism/Post-Impressionism Lecture
This video describes the differences and sameness between impressionism and post-impressionism. Impressionism is about light and color; impressionists draw paintings with color theory, they put colors on the palette, and mix colors, it's called optical mixing. They draw paintings by learning directly from nature. They draw paintings with vivid colors. The painters paint the subject over and over in order to catch the exact color. And the post-impressionists use impressionist techniques but they want to take the style to a whole new level. They paint with more patience, more expression, and use color to communicate about the world; they were searching a deeper meaning in the art.
In my opinion, I can't tell the differences between impressionism and post-impressionism, because I don't have any art sense. But according to Monet's paintings, he used several colors and mixes them, so the paintings are filled with the variation of colors and light; his paintings make the scenery more colorful. In order to create colorful scenery, the painters use colors to cover the original colors.

My Favorite Art
I saw the pictures on http://tinyurl.com/22tu8jo and http://tinyurl.com/2epptc7
The shadowgraphic is a folk art. The puppets are made from animal skin or paper. The entertainers use light to illuminate on a white screen, and perform a show with music and singing songs. It has the fame of movie ancestors. In the past, movies, TV, etc, those media were not popular; the shadowgraphic was one kind of popular folk entertainments. In Chinese history, the entertainers performed shadowgraphics for soldiers; the soldiers had to fight a war in daytime, so the shadowgraphics were their entertainerment at night.
I have seen the shadowgraphic several times. The entertainers play the puppets carefully; they especially have to cooperate in music and light. But as the media has become popular, the shadowgraphic has been downfallen; people seem to forget this traditional performance art. Nowadays, if we want to see the art, we have to go to the museum.

The Painting
The painting by Laetitia was described a situation of a downtown. I saw the residents, cars, children, and families. A woman's car was broken, and a mechanic helped her fix the car. A man pushed his cart and sold something fresh. Probably this painting described some evening; people just finished their work or school and wanted to go home. Maybe there was a school near the street; I saw a mother bringing her children and a father driving a car with his family. A store was crowded, so a woman must wait outside of the store. Some people were living in an apartment and a mother was holding her baby watching those people. I think this painting described the end of a day of a downtown; it was bustling. Probably the artist likes to draw daily life.

Summary - How To Remember Your Dreams
I read http://meaningofdreams.org/dream_recall/rememberingdreams.htm
Dreams happen in the Rapid Eye Movement. People can't remember what our dreams are when we get up. Dreams are like a computer; they record every event everyday. Dreams aren't continuous memories or photographs. Just write down the dreams that we can remember. This is a description about how to remember our dreams.
In my opinion, it gives me a useful method to record my dreams. Dreams are a part of our life; by the dreams, we can understand ourselves easily.

Dream
I have dreamed that something will happen in the future. For example, I have dreamed that I am talking with somebody or doing something a few weeks or a few months later. So when I am at the timing, I fell familiar about my action, disscussion, the person, and the surrounding. Although the dreams don't include bad events, I would like to know the meanings about the dreams. Why do I know what will happen in the future? If I can find the answer, perhaps can tell people what accident will happen and prevent it. Or I have the prediction ability.
