First day of Year 4

CS3216 show and tell

It is amazing to see the CS3216 show and tell. I really have to say that everyone is talented. Computer science major does not imply that I am a good coder. After today's show and tell, I realized that everyone can be a very very good coder and come up with fantastic videos, apps and all the possible things.

I believe that it is no good to play computer games... Girls do not like games anyway. However, it was totally surprise to see the Warcraft presentation today. I am not sure how many coding evolved in order to come up with that video. However, I like the idea. At least, it attracted almost all the audiences when it was first shown (if this class has more girls, I do not believe it will have such good feedback). Anyway, their group picked the correct manner to attract audience~~~ really a brilliant idea~~~

In addition, the bank video is really professional. I tried some of the video editing before. It is really hard to come up such a nice video from scratches.

Should not forget the balanced cars. In fact, the presentation does not show the whole design as we all knew. However, as I was around SoC during the vacation, I know that he stayed in the lab for all most the whole month..... That is Passion!!!

P.S. Strongly recommend to use Aldrian's chatbox. It is very nice but also be noted that he could check all the messages~~~


After today's show, I feel a bit sad for myself. I really need to develop some random things to do when I was free or sad.... Most of the time, I will watch videos...






=======================other story of today========================

Today I wrote that I am passionate about maths. Prof Ben said that I need to take another semester to reform...

I am not sure how to check whether I was really passionate about maths. But I knew that among all the lectures, only the math lecture could make me smile from heart or the things related to maths. The reason is not that math lecturer is funny and interesting. It is the maths concept made me happy without reasons.


Today I had the first lecture in set theory. Sad to say that I did not expect too much from this course. Set, it is just too common to learn. It is a collection of similar objects --- definition from high school... However, surprisingly, the lecturer told us that "set does not have a definition, it is undefined, like you never define what is a number". I was totally surprised. Although all the other stuff he taught later were more or less known, I was still shocked by that sentence. I think he was right because set is the most basic concept of the whole mathematics. In that sense, there must be something undefined and can not be defined. Set is the fundamental concept of mathematics and logic, I guess. After learning some axioms about sets, I suddenly realized that some of the programming languages is kind of replicating the whole mathematics. NSObject, defined in iOS, it is the root object of all the objects. It just like the basic set concept and based on which recursion applied to create more objects. All the logic calculation is replicated by defining built in functions. Sets + Logic, they seem to form mathematics. Then all languages defined in this manner will be kind of replication of mathematics. Wow~~~ It is a huge work~~~ But anyway, I know that it could hardly be a complete replication because there are too many beautiful results could hardly be understood by 0s and 1s only.

Today I was really tired~~~ A whole day lecture. But it really fruitful and at least I did learn something~~~


P.S. I do not believe Prof Ben will read every post...
