stuff that made my day
apparently it's as fluid as glass in there. GLASS! the solid-liquid glass. so that's how fluid it is in there. 70% water, but not free-water.
yesterday's practical. lecturer was going through stuff. mentioned Johnsons and johnsons soap that's advertised as pH5.5 . told us that he put 1g of it in deionised water and it measured pH 6+. 1g in tap water also pH 6+. ??? and then titrated it with NaOH and HCl, no buffering capacity found. so what in the world does the soap do? and what is the advertised pH5.5....
today's lecture too. lecturer was mentioning beauty products like collagen pills. if u eat them, what happens. if u rub lotion on your face what happens. and the sheer price of these products... tsk.
i do dislike biodiversity so. otherwise, almost all lessons are enjoyable. chem prac sux. the chem lab sux too. french is absolutely delightful.
and i want sleep. why is the stupid lecture so early. did i mention that the chem lecturer is insanely slow. ohno what shall i do in chem lect tmr. too bad the textbook is too heavy to bring there to read. the only other module with two lectures a week (french's the other one), and he seems to have taught the least. and with also the least gusto. pathetic.

today's lecture. lecturer mentioned that some guy in harvard did some crazy experiment, went to measure the fluidity of the cell. like how viscous the cytoplasm is. used a nanoprobe to move a molecule inside the cell. published results last month and shocked everyone.
