Among several activities with which I have already be involved, “Explore the Nanoworld” is the one bringing the most joy, that I specially want to mention.A sophisticated instrument was used in this lab experience activity, that is, the so-called scanning electron microscope which is able to zoom in to a 10 to the power of -9 scale. The excitement resulted not only from the fact that I had access to operating the giant electrical monster myself, but also from the kind of experience it brought with.
The scanning electron microscope which worth million dollars lied in a quite corner of the physics department. The pictures below were taken by me, during the observation of different tiny objects in the lab.
It is a picture of the head of an ant, in which we can distinguish both eyes of it. It took great efforts before I finally managed to find the right angle to capture this photo.
You may be puzzled by the peculiar patterns in this picture. Guess what is it? It is the surface of a cockroach(a kind of insect called by lots of us’xiao qiang’)’s leg!!! 
This one may be quite common in our daily life, not that disgusting as the above. Just a simple piece of paper. 
It is a stomata which is usually find on the surface of a leaf. Gas for essential respiration goes in and out this tiny hole. 
It seems to me that this picture is the most meaningful one since it is my hair!!! At least, I hold this and keep this, make sure that many years later I would have unique and precious memories to fall back on. 
A lot of more things lying ahead for me to explore and see, what is my next stop? Who knows? ^_^

Oh wow!
ReplyDeleteThank you for sharing with us these beautiful and lovely picture. I am very impressed by your picture and your words. It was so lucky to explore the nanoworld, and I think that it will become one of the most precious memory of your life.You have such a large vocabulary that you can express yourself so well that we all can understand you very well.You are so enthusiastic that you have explode a lot of the activities in NUS and paticipate in them. I think it is very good for our students. But I seldom pay attention to them. So that I think I should learn from you and next time you have got this kind of imformation, please inform me. Thank you!
ReplyDeleteHi Veronica, this is interesting reading. But I am not into such details in science. I watch a lot of animals and nature programmes. You can go to nationalgeography.com : the articles are very educational, from animals to science and technology. A few years ago I read about the photo-journalists, that is the photographers. To get one picture of animals published: Yes, just ONE, you take an average of 650 shots. Well, we can;t tell animals to 'behave'.
