Railroad Train Guidance System

As promised a while back, these are the video clips that were taken today to show how our train system is operated under the Boolean Logic Equation that we made. Watch the video clip carefully you will notice the train would never ever hit the plastics on track. Below are two clips.

The trouble with so many of us is that we underestimate the power of simplicity.
We have a tendency it seems to over complicate our lives and forget what's
important and what's not. We tend to mistake movement for achievement. We tend
to focus on activities instead of results. And as the pace of life continues to
race along in the outside world, we forget that we have the power to control our
lives regardless of what's going on outside.

Wonderful Problem (Chinese Version)

If you can answer this problem in 5 minutes, it means that you will be to master polythinking.
"村子中有50个人，每人有一条狗。在这50条狗中有病狗（这种病不会传染）。
于是人们就要找出病狗。
每个人可以观察其他的49条狗，以判断它们是否生病，只有自己的狗不能看。观察后得到的结果不得交流，也不能通知病狗的主人。
主人一旦推算出自己家的是病狗就要枪毙自己的狗，而且每个人只有权利枪毙自己的狗，没有权利打死其他人的狗。
第一天，第二天都没有枪响。
到了第三天传来一阵枪声，问有几条病狗，如何推算得出?"

Civilization and People in the Society

Looking back to the long path of our human history, we can see that our great ancestors created many wonderful civilizations. We feel astonished and proud of our ancestors. However, it is not the time for us to do that right now. Now, we need to think deeply about this question: How do civilization and people in society influence each other?

Reading the great psychologist Sigmund Freud’s Civilization and Its Discontents, we will learn more about this issue. In Civilization and Its Discontents, Freud said: “We recognize as cultural all activities and resources which are useful to men for making the earth serviceable to them, for protecting them against the violence of the forces of nature, and so on" (42). The quote means with the help of their wisdom, humans made themselves more suitable to live on the earth. They could protect themselves from the damages of nature. In addition, Freud said:” With every tool man is perfecting his own organs, whether motor or sensory, or is removing the limits to their functioning" (43). As humans got used to the surroundings where they lived, they began to build up more and more things that could improve their lives. Gradually, civilization was set up.

However, not everyone will be satisfied with the civilization of the society they live in. In Civilization and Its Discontents Freud stated: “The liberty of [the] individual is no gift of civilization. It was greatest before there was any civilization, though then, it is true, it had for the most part no value, since the individual was scarcely in a position to defend it. The development of civilization imposes restrictions on it, and justice demands that no one shall escape those restrictions” (49). What Freud said indicates that the civilization is the common wealth for the majority of the whole society. If anyone goes against the civilization due to the desire for the liberty of individual, he or she is about to be punished by the restrictions which are made by the civilization. At this time, the minority in the society who goes against the civilization may separate into two groups: loyalists and rebels. The loyalists may have to suffer the force which is in opposition to the individual’s wishes and rights. However, “the urge for freedom, therefore, is directed against particular forms and demands of civilization or against civilization altogether” (50). The rebels will keep on their struggles no matter how the society suppresses them. As the struggles enlarge, more and more people in the society join in the struggle. At last, the strong group of the rebels may pull down the former civilization and build up a new one. That is how one civilization subrogates the other civilization.

One the other hand, we can get a similar idea to Freud’s Civilization and Its Discontents from Aeschylus’ Prometheus Bound. In Prometheus Bound, without fear of the dangers of stealing it, Prometheus brought mankind fire to lead mankind a bright future. After his stealing fire, Prometheus was nailed to a cliff as penalty by Zeus. From here, we can see that Prometheus is acting as the rebel against the civilization created by Zeus. As he went against the restrictions of Zeus’ civilization, Prometheus was punished. However, no matter how the God of the River Oceanos, who was afraid of Zeus, advised him to yield to Zeus, Prometheus insisted that "I shall drain myself till the high mind of Zeus shall cease from anger" (377-378). As a rebel, Prometheus still kept his will, which was to bring liberty and a bright future to mankind; he kept on his struggle against Zeus. Prometheus was not struggling by himself. The Oceanids, who are the daughters of Oceanos, gave great support to Prometheus. On hearing of the affliction of Prometheus, the Oceanids blamed Zeus's violence. Though their father, Oceanos, came to persuade Prometheus to change his mind, the Oceanids still stood on the side of Prometheus rather their father. The Oceanids kept on searching for the truth with their eyes and ears, listening to the whine of Io, blaming the arrogance of Hermes. At last, without any fear or regret, the Oceanids fell deep into the underground abyss with Prometheus. Why did Prometheus and the Oceanids go against Zeus? No need to say, it was all due to the irrational force from the Zeus’ civilization. The restrictions of Zeus’ civilization went against truth and justice. They needed to struggle for truth and justice. Now, we can see that if the development of civilization goes against the original will of the people, it will lead more and more people to feel unpleasant about the society and stand up to go against the society and civilization.

In a word, though the people create the civilization, the restrictions of civilization will suppress the liberty of the individuals. However, if the development of the civilization separates farther and farther from the will of people, the civilization will become unstable and easily fall down.

Computer Science VS Computer Engineering

Similarity:

Both majors interact a lot with computer technology, keep up with the latest computer trend.

Difference:

Computer Science is pure software programming, while Computer Engineering programs and also make magical happens in your hands!

Pros:

Computer Science is very interesting to learn, once you master one single programming language your life won't disappoint you anymore; as a Computer Engineer, you not need to worry about job opportunity, with both versatility in programming and engineering, its very easy for you to learn other engineering professions quick and fast.

Cons:

Computer Science is bored in a way if you can't memorized all the different codes in different programming languages and your career is only limited to computer industries programming all day long in front of a computer; although Computer Engineering is more versatile than Computer Science, it is hard to master both programming and engineering at the same time as your advance onto higher level classes(considerd my P.S. notes below), and worst of all you might end up learning nothing at all.

7 Important Experiences from Poly by Jason Zheng

Experience One: Be Proud of Yourself
In college, no one will like to be proud of you until you give benefits to them. So, why not feel proud of yourself?

Experience Two: Be predential to all your work
I remember what my English Professor Alph Edwards said in English class: "Try to image ten years later, when you write a report to your boss, if you want to show your preciseness, the interpunctions will tell everything."

Experience Three: Be good at communion
College is an inspissation of the whole society. If you are good at communion, you can gain a lot of good results.

Experience Four: Be active to make friends
Friends are not esay to make in college. However, keep your bravery and activity to chat with the people next to you. Later, he or she will become your reliant friend.

Experience Five: Be aware of your grammer mistake
My grammer mistakes often lower my English paper's grade. So, before you start writing an essay or a report, make sure that tell yourself pervent the grammer mistakes.

Experience Six: Be in balance
Though college gives you a lot of tasks, you still need to do some sports or join some ativities for the balance of life.

Experience Seven: Be sure who you are
Try to think where you are standing and which direction you are going to. If you find you are in the wrong direction, no need to feel depressed, just change your path at once.
