French Cancan

Bonjour!

Believe it or not, yesterday I had register myself to a French Cancan: French conversation group for beginner. The session will only be one and half hour per week every Wednesday and will be going on until April 1st. It is an informal session, with no pressures, no exams and just having fun. This is why I sign my name up. Also it is free for any Concordian with a valid student card. The group consists of approximately 20 people, and most of us are not from Canada. Most of them also have taken a basic course in French while, I have none, zero. So, truly I am an original beginner.

The first session was trying to know the pronounciation in French. Everybody were introducing ourselves and after that we need to introduce ourselves again in French. It is kind of tricky and I kind of split my tongue a bit. Though I managed to introduce myself in French for a first time. Who cares if I pronounced it badly or incorrect. As long as it sound like French, it'll be OK. hehehe...

As the instructor was saying, the key to success is your self-esteem. Don't be afraid and be brave to spill it out.

Measure Theory Demystified #1

The concept of measure is a generalization of the concept of "length", "area" and "volume". The famous theory of measure would be the Lebesgue measure which associated to the Lebesgue integration.

Every definition of an integral in based on a particular measure. I never learned such integration is integrated with a particular measure. I mean not in a normal integration.

For example,

1. Riemann integral is based on Jordan measure
2. Lebesgue (pronounced ləˈbɛg) integral is based on Lebesgue measure.

These two famous integrals usually encounter when study of analysis of functions (reals or complex). Lebesgue integral for example plays an important role in the branch of mathematics called real analysis and in many other fields in the mathematical sciences.

Remark: The study of measures and their application to integration is known as measure theory.

Discussion #...

Today is Monday, the beginning of the new week. It is warmer, with light snow and also very quiet. I was the only student in the office. Even after my usual discussion was finished, there's no one else coming. Also my friend Valerie, she is not coming to the office either. After all, I just found out that I will be left 'alone', as everyone else is finishing soon. Alone in the sense that the only maths physics student left. The rest of us were doing the actuarial maths, maths plus financial interest. It is a very popular research here in Concordia. From my observation, most student who taking actuarial maths is Chinese. Current news proposed, if they performed very well, they can be hired by a multimillion financial company for example an insurance company. This is a very good job prospect to be aimed for. Yup, Chinese is equivalently to business minded. So I guest they follow the right track.

If to compare with maths physics. It is kind of massless. We need to pull more crowd. I've talked to my supervisor and he mentioned that he currently focus on me and only me. The most student he had one time was two. As he was saying, supervising maths physics student is totally different from supervising an experiment base student per se. (Yeah, its not like I don't know about that). He did had another student from University of Montreal but yet he just being the co-supervisor. Though she also quite finishing. Valerie like I said is finishing this coming summer. As a remark there are many maths physics professor here (five of them) in Concordia, but less potential student.

Second Lecture on Lie Groups

Last week, the teacher started his first lecture on Lie Groups in giving definitions on groups and stuff like that. I'm going to summarize later on (in my own words) basic important definitions that going to be understand when we learned about groups specifically the Lie Groups. Today is just the continuation from last week topics, but a little depth on the representation theory. Personally I need to work out on this one since I don't recall I have ever experienced this subject before.

It is a good practice for myself to be able to put some details on the web as my own personal (input) database which going to be useful in future. This is a mathematics class but I don't see any numbers and a common mathematical work being presented through out the lecture.

Note: I am so dense!

-22 Degree

Patutla masa cik salma nak pergi ke sekolah pagi tadi, rasa sejuk semacam. Tak pernah lagi rasa sesejuk macam ni. Sampai di office, terus semak weather forecast untuk hari ni, rupanya -22 degree which correspond to the -33 feels like degree. Cuaca di luar memang cerah. Sinaran matahari begitu terik. Tapi sayang kami di bawah sinaran matahari kesejukan.

Nampak gaya lain kali, kena pakai seluar tiga lapis, baju pun tiga lapis juga.

Note: Di kala ini, tak sabar nak tunggu salji turun lagi.

Pretty Bad

I received an email later today from our graduate assistant. She mentioned that she has to withdraw my name from the course that I have registered for the Winter term, Mathematical Quantum Mechanics due to the low enrollmment. There are only two of us. I was sad about the news since the teacher for the course is my supervisor. During our first lecture, I was kind of excited to listen to his lecture.

It was more than just a lecture. He inspired us with a very nice starting through intuitive examples of quantum mechanics. In my early days, it is far well-known that subject on quantum mechanics is less interesting to students due to its depth abstract mathematical usage which is unreachable from any ordinary imagination. But believe me. Once when we get to its roots and terminologies, it was really interesting. There are many to relate to the physical world but of coz there's more open question about its existence.

I really hope that I can still have a chance to take this course. I have more years to go. This is something that I really needs as to practice myself to become a good QM teacher one day.

2009

I believed that everyone now must have encouraging setting up their 2009 resolutions. I wish all the very best to every human beings on the planet...
