HK Museum of Medical Sciences


The bubonic plague (腺鼠疫) occurred in 1894. Two pathologists came from Japan and Switzerland discovered and isolated the bacteria. Old Pathological Institute commemorates their achievement. This heritage is now the Hong Kong Museum of Medical Sciences. The museum is an Edwardian (愛德華時代) building with brickwork and arched verandahs (陽台). It has exhibitions on local medical history including SARS. There is a herb garden outside the museum displaying some basic ingredients of both Western and Chinese medicine.

為何車輛轉彎時會傾斜?

In the diagram above, the school bus is turning right and tilts outward.
Total friction given by tyres and road provides centripetal force for circular motion.

C.M. : center of mass
N : Newton due to action-reaction pairs
f : friction
CW : clockwise
ACW : anti-clockwise

Before flipping over of the school bus,
f1 + f2 +N1 = N2
N2 > N1

Therefore, the car tilts outward during the circular motion.
