wednesday - 18/1/2012 - A trip to her house

Last August, I have taken a trip to Dong Nai province - Trang Bom, near Tri An junction to her friend's house. This time, I also come back to Dong Nai but I go to Bien Hoa city - her house.  
The previous time, I went with the guy name Phuc - the guy study with me in university. This time, he doesn't. I go with Phuoc - my closest friend in high school. He is a very IT person, a man interesting in photographing and he is very shy said.

I have one thing (very excited) before I go. It was the Tuesday (17/1/2012). I did the clean of my house for all the morning. When I got free time in afternoon, I run the code. The stress made me sleep without knowing. When I got up, the headache was so terrible, the body was so tired and my throat was hurt. After finishing cleaning house, I only lied in bed. You know...It's so terrible to get illness when I have to go a trip tomorrow... and one more important thing is that my Mom won't let me go if I just like that.

Althought being tired and so worrying about the trip tomorrow, there was one thing make me interesting. I have a chance to check the so-called pulse (get the pulse of your heart at your wrist), the thing that traditional medicine doctor often do to diagnosis . I try and get my pulse about 109 pulse per minute. The normal pulse is 60 - 100 pulse per minute. If the pulse is much more about 8-10 pulse per minute than the maximum normal pulse, I get one celcius than the normal temperature. Which mean, at that time, my temperature might be 38 celcius. I use the thermometer to check it out and the result is very exact. Great! I still do the pulse while I lied and waited for my dinner.

Back to the trip. I sent the message to Phuoc about my situation but not to her beacause I still hope that I would get better after I take medicine. I lied and waited for the better situation. My friend continously ask me about the health, some thing like: how are you going on ? Feel better or not ? If dont sure just call her and cancel ... Luckily, I found myseft have a little bit better, so I decided the trip would be taken. 

Before going, Phuoc asked me if he should bring his photographer. That is a professional photographer that he got from the auction from USA with the cost is 4 million VND (he told). It is important for him because he will use it to join the Sai Gon's photographs contest after Tet Holliday. It's photo is great. (If you dont belive, just go to: http://www.facebook.com/profile.php?id=719605865). So I advice him not to bring it beacuse it is very complex when we  are on the bus.

Tomorrow, I still not very healthy, but I still decide to go beacuse long time no see her, I want to see her so much. Mom let me go but  don't allow me to use my motobike. So Dad takes me to my friend's house. There,  we take the bus to Ben Thanh market and then take a bus number 12 to go to Dong Nai. It costs us 20 VND each person. We stop and Suoi Linh petrol station. She and her friend come. There are 2 motobike, I take her and my friend takes her friend. We go to her house. Exactly to say, we go to her brother's house. It's difficult to describe. Her house is at thr front and her brother's house is at the back on one square land.

Her house is very good, quiet, cool, get a lot of trees, bananar trees, garden for planting, a grden fro growing chicken... Just like:





And this id the my friend. He is so shy saying (but he says so much with me). He spends all time for TV and watching the sight, doing with the card.

I also meet her brother and her sister in law. They are so friendly and cook so well. We have luch with chiken sallad, fried cow-meat, fried fish and mushroom hot spot. Very great! Then I help her to wash the dish and everything while everyone play card.
2 PM, we decided to go somewhere. We go to Tran Bien Temple. It's very nice with sight-seeing. My friend blame me about advicing him not to bring photographer. Haha! I told, dont worry, just use my phone. He still be bitter.
These are some sight-seeing we take by photographer:












5PM we go to bus station and say good bye with her. I and my friend sit a long time at the bus stop to wait. The final bus finally come at 6h15PM. I go to his house and wait for Dad. He told me to have dinner at his house. The dinner is very simple but very great: rice bowl with chicken stock, pork stock and the fast noodle as a soup.
The happiness in the trip help me to eliminate my illness. I feel healthier. I also miss her. Hope seeing her soon.

Bài giải và chia sẻ kinh nghiệm hồi thi môn vật lí thống kê

Chưa bao giờ tôi bị áp lực thời gian nó đè nặng đến mức khó thở trong phòng thi như khi thi môn Vật Lí thống kê vậy. Điều tôi cảm thấy tiếc nuối nhất là tôi đã không giành một ít thời gian ngồi phân tích thật kỹ đề bài trước khi làm mà cứ cắm đầu cắm cổ vào làm ngay câu 1. Và kết quả là tôi đã phung phí 1 tiếng rưỡi đồng hồ cho nó, và sau đó là cuộc rượt đuổi thời gian để làm câu 3 và câu 2 trong vòng nửa tiếng để cứu vớt lại 2 điểm cuối cùng nếu không có thể tôi đã trắng tay với cái đề này.
Thực ra thì trong đề này, câu dễ nhất lại chính là câu 2 (Các bạn sẽ thấy nó dễ như thế nào khi xem bài giải dưới đây). Câu 3 cũng là câu để lấy điểm. Nếu như xem kỹ đề trước khi làm, thì tôi đã làm câu 3, câu 2 trước rồi. Ngoài ra câu 1, câu 2 nhỏ của câu 1 cũng là câu để lấy điểm (nếu như không có sự tranh cãi về cái hệ số g có chứa epsilon mũ 1/2 hay ko). Nói chung, đề bài này có thể lấy được 8 điểm.
Vì vậy, tôi xin rút kinh nghiệm, bất kì lần thi nào sau này, tôi sẽ phải dành ít nhất là 5 phút ra để đọc kĩ lại cái đề bài và làm những câu dễ nhất trước (trước đây tôi vốn bảo thủ, dù câu khó câu dễ, tôi đều xơi từ đầu làm theo thứ tự cả).
Đó là những gì tôi muốn chia sẻ về kinh nghiệm thi môn này. Hy vọng tôi đủ điểm để qua được môn này.
Còn dưới đây là bài giải đề thi vừa rồi tôi giải lại và up lên luôn. Tuy nhiên, câu I vẫn chưa hoàn chỉnh, tôi đang chờ phản hồi từ anh Hưng và có gì sẽ update lại sau nhé.
