Some pics to share

Pics from the last analytical lab. Compared to physical chem lab, i found that analytical really rocks. Lol. But of course the lab reporting does not rock at all~

1st pic is on fluorescence spectroscopy. The first time i saw the blue light when i placed the cuvette cell in the sample holder i got super excited bcos i found that i could finally appreciate something in chemistry lab. Anyway the blue light was really beautiful, and for once i didnt mind staring at it longer and ending lab a few minutes later. Its not that well captured in my camera phone though.

2nd pic is on High Performance Liquid Chromtography(HPLC). Didnt really know how to appreciate chromatography last time. But through this lab module got to understand it better and find that it is very applicable in chemical industries. The bottles on top are reservoirs for gradient elution to separate out the components. Everything is computerised and the equipment looks huge.

Wanted to take a pic of the Atomic Spectroscopy machine but wasnt in the mood while doing the experiment bcos we had to queue and wait super long since there was only one machine and 5 groups were doing the experiment. The flame in the machine really looked cool~ The flame was used to atomize the sample and absorption was measured.

Lol am i missing chemistry already? Have never regretted switching to Chemistry after my first sem though i lagged behind in modules. Only regretted not making the right decision earlier :(

Reaching the end~ Can finally see light at the end of the tunnel~

Took my 2nd last final year exam today..Still ok. But somehow didn't manage to churn up the length for the first question which was a 50 mark essay. Sat there in the last 10 mins with mental block, and somehow i didn't feel nervous at all. Just felt that my brain had shut down. Guess i was too tired to think. Ended off with just one single sentence 'urban planning is needed for economic growth but the government has to intervene as well'. Wanted to write more but my hand was no longer responsive to the signals sent out by my brain. Lol.

Yesterday's biomolecules was the worst paper i took this sem. Just by looking at the paper i had already lost half of the marks bcos i didnt focus on memorising those stuff. Somehow i was caught off guard, and felt kind of cheated. Bcos what came out in some of the questions were those not explained in detail by the lecturer and i thought was just sufficient to understand and glance through. All the stuff which i thought was important and focused on did not come out much at all.

Haiz i have a bad bad habit ever since i came to NUS. I cannot sleep well before major exams. I go to bed early, ensuring i have more than 6 hours of sleep, but i somehow i toss and turn about in bed, and the next day i just feel so tired. Ironically, during normal school days i would treasure every moment to rest and sleep. I will doze off in less than 15mins. Is it a psychological barrier towards exams? It only started from year 2. In year 1 of uni i was too slack to bother so much.

I just realised that it is hard to ignore and feel angry over loved ones. Although i feel angry and upset sometimes, i just cant bear to show the other person how angry or upset i am. After i show that im angry or upset i regret my actions of being too harsh. Is this a stong feeling of love?
