     Reading week is coming and I don’t have any planning. The girl who has class with me dropped this course, so I also consider whether I should give up this course due to the low mark of last test. After talking to my mum, I still decide to keep working in it.

Last week we learn binary system. It is not that difficult because there are similar between binary system and decimal system, and we started to use decimal system in general mathematics when we were young. However, two states is the smallest so that binary system is the most easily designed in computer science. Decimal system is multiply each digit by the appropriate power of 10, and binary system is multiply each digit by the appropriate power of 2. For example, 1011=1*1000+0*100+1*10+1*1 in decimal system; 1011=1*8+0*4+1*2+1*1 in binary system. It is not that complicated. In addition, I found that the video is very useful for comprehending contents and finishing quiz. ;)

     I forgot to update slog because I got 2 tests and 3 assignment last week.   From start to now, this course is quiet easy, but I still cannot comprehend completely due to my negative attitude of studying. After finishing CSC test, I felt horrible. It is obvious that professor only wants to check the basic thing about our learning contents and details in this test instead of difficult things . However, I still lost a number of marks which should not lose. It feels bad. Maybe I should recognize that I put less attention than I'd expected. My major is mathematics, and I always believe that there is a great number of relationships between computer science and maths.
    No matter how bad today, tomorrow is still wonderful.

     This is the third week of this semester, I feel that time passed so quickly because I really enjoy this course. This week we learned something about the history of computing devices. A long time ago, computing devices are not as smart as they are today. At that time, they can only do some simple computing. As the time goes, some computing devices, however, are invented to process complex computations and finally the mass produced computers whose name was UNIVAC appeared. It is said that UNIVAC was the first computer in the world and it is the best invention in the recent 100 years. This history was miraculous and it changes our life. We also learned how to rotate an object with codes, although I was not clear. Next week we gonna have a test, and I believe that I can handle it. J
