The 2001 Pacific hurricane season was a near average season. The most notable storm that year was Hurricane Juliette, which caused devastating floods in Baja, California, leading to 12 fatalities and $400 million worth of damage. Two other storms were notable in their own rights, Hurricane Adolph became the strongest May Hurricane until 2014 when both records set by Adolph and Juliette were broken by Hurricanes Amanda and Odile. Tropical Storm Barbara passed just north of Hawaii, bringing minimal impact. The season officially began on May 15, 2001 in the eastern Pacific, and on June 1, 2001 in the central Pacific, and lasted until November 30, 2001. These dates conventionally delimit the period of each year when most tropical cyclones form in this part of the Pacific Ocean. The first storm developed on May 25, while the last storm dissipated on November 3.

材料科技史

自从人类诞生以来，材料科学已经塑造了文明的发展，更好的工具和武器材料使人类得已传播发展及征服领土，如钢铁和铝等材料的生产或加工技术仍持续影响着当今的社会。历史学家认为材料是文明的一个重要方向，因此用整个时期的主要材料作为时代的命名。对于大多数有纪录的历史，材料的控制充其量只能透过炼金术或经验的累绩。化学和物理的研究及发展有助于材料的研究，从这些研究中融合产生材料科学的跨学科研究。材料科学史是研究地球历史和地球上的人类文明，是如何受到不同材料的影响。

連儂牆 (香港)

香港的连侬墙指的是2014年雨伞革命和2019年反对逃犯条例修订草案运动期间所产生的粘贴标语讯息等的民主拼接墙。2014年雨伞革命期间，连侬墙首次出现于金钟夏悫道香港政府总部，并被视作当时金钟“占领区”的主要地标，是一个要求特首选举民主化的集体重大雨伞运动艺术作品。2019年6月，香港政府总部再次出现连侬墙，以反映市民对反对《逃犯条例》修订的心声和对示威者的支持。其后，香港各区居民自发于当区开设连侬墙，以鼓励市民为香港打气及表达对政府于《逃犯条例》修订过程中处事手法的不满。至此，连侬墙不再局限于金钟一带，而成为普遍覆盖全港十八区的社区性民主墙。
