Body language

Body language is an important part of communication, which can help you to communicate well and understand other people. For this reason it is very useful to learn body language. Here are some movements, which are the most common.
First, don’t be afraid to take up some space – taking up space, for example, sitting or standing with your legs apart signals self-confidence and that you are comfortable. If you are listening to a person it is recommended to nod, it shows that you are listening to him, but don't overdo it, it can look stupid. And another important thing is not to stand too close to a person when your talking to him, because you are interrupting his private space, which is impolite and may signal rudeness.
It is also important to understand when other person is lying. persons who are laying may be very anxious. Many of us have hidden anxiety signals. For example: Biting the inside of the mouth, patting head, hands in pockets. Anxiety may be displaced into actions such as fidgeting, moving around the place or paying attention to unusual places.
Here are only few movement mentioned, but there are hundreds of movements to understand. However, we have to be critical because, for example if a persons sits with his arms crossed on his chest it could also mean that he is just cold.

Artificial intelligence

According to http://library.thinkquest.org/2705/, Artificial Intelligence (AI) is the area of computer science focusing on creating machines that can engage on behaviors that humans consider intelligent. But some things about this intelligence makes me wonder. What place does it take in our society? Can a computer express emotions? Can a computer have a mind?
Artificial intelligence is created by humans and it's purpose is to help people live easier life and to make daily life activities easier. Computers helps us every day to solve difficult tasks, that would take lots of time to do it for our selves. But however, in my opinion, computers do everything automatically and such point as emotions, or separate mind can't be considered. In addition, off course, there is possibility that many years after the situation will change and then we could talk not only about artificial intelligence, but also about artificial emotions or mind. As professor Floridi said: "We do not know if we are the only intelligent form of life. However, we are now slowly accepting the idea that we might be informational entities and agents among many others, and not so dramatically different from smart, engineered artifacts."
All in all, artificial intelligent couldn't exists without humans. It shows a significant termination or unlimited power of humans capability. And artificial intelligence is created only to help people to live an easier life and to answer of questions and to broaden our knowledge of the world, but not to replace us.
