每当发生重大航空事故，飞行安全就会成为话题。想必很多人听说过飞机是最安全的出行方式。另一方面，若问哪种交通工具让人最有忐忑感，答案多半也是飞机。飞机究竟是不是最安全的出行方式？在一定程度上取决于定义。在维基百科有一组统计数据从一个侧面显示出定义的作用。

从这组数据可以看出，如果安全性定义为每次乘坐或每乘坐单位时间的死亡风险，飞机都不是最安全的，但由于飞机的平均旅行距离远大于其他出行方式，因此若将安全性定义为每乘坐单位距离的死亡风险，飞机就变得最安全了。从这组数据还可顺便看到，按所提到的每一种定义，摩托车都是最不安全的。

普契尼歌剧《图兰朵》的七个旋律，四个来自在清朝海关任职的比利时人阿理嗣1884年出版的《中国音乐》一书（上海别发洋行Kelly & Walsh Limited），三个来自Tancredi Fassini Camossi男爵家的八音盒，这八音盒中就有我们熟知的《茉莉花》。男爵在庚子之乱时曾是驻华外交官，有人猜测这是拍卖回来的战利品。

竺可桢1948年3月18日记：晨六点半起，盥漱后整理行装。早餐后与晓沧、廉先二人乘考选委员会车赴下关，由工役老丁送至车站。此次高考，院中各送川资三百万元，头等车自杭至京一百廿二万六千元，来回二百四十五万二千元，两天膳食与茶房小账，虽不行动，己三百万矣。余与廉先坐头等车，晓沧坐二等车，二等稍挤，头等车则甚空。余在车中阅书时多，头、二等亦无甚分别也，二等车价亦八十二万八千。

In March 1948, the Kuomintang's financial policy failed, resulting in severe inflation in Shanghai. Wages were paid daily, requiring large amounts of banknotes for payments. Consequently, cash had to be transported in large bags, making everyday transactions increasingly difficult for the citizens.
