Dear my friends, Everything become so blurred to me, I dont know what I should do for life. I used to be very ambitious and want to be a good physicist, because the beauty of Nature has been fascinating me for a long time, since the first day I read Einstein Relativiy. But, as I grow up, I realise more and more. Everyday, thousands of people are suffering from poverty, famine, war, deaths, and so on. Can I still be so ambitious and say that: "I want to be a good physicist because I want to study "Nature's beauty"?" Wrong, I find it is wrong, when people are suffering, I am sitting in office, and "do research???" My dream turns out to be so luxury, and I feel guilty. Sometimes I told myself that, "hey, you can make use of your physics knowledge and help the other!" Can I? I study physics is because I like it, the reason is very simple. I just want to understand everything around me, that is all. If I make use of my knowledge to do something "practical" in helping people, I find that, this is not what I personally dream of! I would say, I find that, doing "fundamental" research for understanding Nature is too extravagant, especially when we realise that everyday, thousands of people die in famine. The problem is: My personal dream is to do "fundamental" research so that we/I can understand further about Nature. But, this dream turns out to be so extravagent, as it does not help to those unfortunate people at all! Finally, I would like to ask all of you, what is LIFE? If we must die, I mean all the mankinds and even the universe, why we live and why we study further? Shall we hence stop to do "irrelevant things", and try to make the people around us as happy as they deserve? Shall we stop our "impratical dream", and try to make the world more beautiful and ideal, rather than always try to achieve our personal dreams? Please guide me, Thanks, Twukwuw.
