oh!!!! i'm so stress today...the physics experiments are so difficult although i had done a little bit similar experiments at the matriculation but i'm still blur to do that experiments. i'm, pika and ros do that experiment slowly until get the results. firstly, we done that confidently. but after my friend ask the lecturer, we have wrong concepts. that so funny. so we repeat the experiments with the true concepts. after get the results we still had problem. we not really sure to calculate the data. but, its okay because, the lectures just to look the results only not the calculation.so, we are lucky. we went home early today n went to KUO to bought foods. although, my timetable today is not pack but i'm felt very tired. so i want to rest now..see you tomorrow:)
