My issue
|
||
|
I was thinking too much and being aimless. Suddenly I realized that we all have our own businesses,everyone has his own thing to do,working in the government,in a company,selling friuts in the street,working in a supermarket,cleaning the buildings or streets,or being a teacher,being a farmer,whatever.So what do I do?I am here studying material,this is my job.One shall do a thing seriously, carefully and diligently as long as he is doing that thing,and will be still doing it in a future period. And this is my business.I have a feeling that I have found my way,however long and difficult it is.This is my issue.The first day when I came here I thought I would learn something else in my spare time and I did not inquire myself to do well in my study,sincerely.Because I never thought I would get stuck in material forever,as it is not a good job for a female according to people's words as well as my own opinion.But now I think I have changed my mind,I should work hard on it,no matter I would stay in this field or not.As I have learned it,I shall be good at it,at least,I shall do my best.And actually,I assume I want to do this job in future,I am tough. It is kind of a pleasure to find out where I am and what I am doing,as I am not always aware of it.  [ Last edited by 1043109135 on 2010-6-1 at 21:48 ] |

I think there is a great mystery. Why is glass transparent? Usually when the atoms in some material are arranged regularly, that material can let light penetrate and look transparent. This phenomenon often happens in crystals(晶体). But glass is not a kind of crystal. So, why is it transparent? Could you please tell me? Thank you very much!  |
