implicit differentiation

chemistry and physics lessons were fun. i rushed to complete the mindmaps on organic chemistry that mr tham gave out. it was so fun! i think i could do very well in the promotional examinations (and win shanghui)! somehow, i've started to like physics a lot. i don't know, is this too late to start loving physics? or do people think that no one can ever love physics?

lunch was at food junction. weiyang didn't appear for lessons today, and we also don't know where he was. so only beejuan, siuchu, yiyan, jia en and i were at food junction. we were all sitting there until quite late, making stupid jokes. must tell toffa about the karate dog!

did you run past my classroom today? i happened to fall backwards and knock into someone when i was looking at you in the canteen. i miss you, hope you do well in the examinations. i miss you a lot, actually.

you've been noobified by 2,4-dinitrophenylhydrazine. it can distinguish an aldehyde from a carboxylic acid, but you can only do so by tasting/smelling it.
