Summer break?

Back again... Now is 2 weeks into the summer break. For the last 2 weeks, it's some outing plus badminton and doing powerpoint slides for the upcoming physics enrichment camp. For this past 3 months, i have been tasked to do 3 power presentation, and of which 2 i have to present alone. To be frank, i actually like presenting, and i will really take out some time and think about how to structure my slides as well as how to make an impressionable presentation. I think as a presenter, we are acting as a mediator between knowledge and audience, and an engaging and successful presentation will allow the audience to gain as much information as possible. Of course this will be only important if the presenter actually care about whether the audience are learning anything. One of my better presentation is about the "philosophical and physical aspect of time". It received quite a lot of positive feedbacks from my prof and fellow classmates. The upcoming presentation topic is on "physics of fluid". Hmm.... it is an interesting topic if all the mathematical formalism is included, but since the targeted audience is JC and secondary, i guess minimal maths should be included and try to relate it to their everyday experiences. haha.... i am almost done with it, just that need a few of my friends to vet through. Yeap....

When holiday break comes, some people will ask me what am i doing, and when i replied, i m reading up stuffs, they often gave replies like,"holiday already, still study?" haha.... well, reason is pretty simple, reading and learning is a passion to me, just like how people will spend hours playing computer game during holiday, or doing window shopping, basketball etc. But again, this reflects what some people attitudes are towards studying or learning per se. It seems that studying/reading has become a duty that will only take effect during schooling period of the year. Reading is a good way to learn and to develop a broader mindview. It also allows us to appreciate the world that we are living in much better. To quote, "To question is to know; to know is to understand; to understand is to live".

while i was playing badminton, i saw some uncle using knee guard and elbow guards etc. I offer some advice, like constant reliance on these arent good, but they rebutted putting in way as though i am wrong. Of course, i dint persist in the argument but it struck me that, "what does it mean to know", because obviously i have good reasons to support my stand while their arent as strong. Upon thinking through and observing, i think not only the the uncles i saw in badminton, but most people always insisted that their "facts" or opinion are the correct understanding. Again, assuming that there is only one absolute reality, all of them can't be right at the same time(unless the facts are disjoint). Which means some of the "facts" are logically wrong, then it is funny to see how some people can always be so affirmative towards their "facts" . I think the main issue here is, to be open to ideas and always be ready to accept new "facts" that will subvert the original one. 虚心向学. Also, the level of education does not neccessary make one know more, because personally, i have witnessed people with higher qualification thinking that their views are the stronger one. In actual fact, with constant education, people should realise that "the more you know, the more you dunno". This is very true, let's take my field of interest for example, intially is newtonian mechanics, f=ma, then it extented to special relativity, then ended up with GR. The facts we know are subjected to changes and refining, so a receptive attitude is a must.

This is just a portion of what i've noticed during the free time in holiday. haha... well, free time allow me to think and see things which are usually overlooked when i'm busy. Oh yes.... back to reading my quantum mechanics. Bra... ket... feynman path integral... dyson series... argh...
