城里有个难念的招牌

某日food hunt途中，在一条小巷里发现了这个招牌。虽然招牌上的字并不特别深，可是还是得想想才能把招牌一口气念完：

马(ma)来(lai)西(xi)亚(ya)徐(xu)余(yu)涂(tu)佘(she)同(tong)宗(zong)会(hui)

Aubergine vs Brinjal vs Eggplant

以前一直很好奇茄子为什么称为eggplant，不管从哪个角度它都不像蛋啊？！

据闻eggplant这个名称源自于一种白色或奶黄色的圆形品种。在18世纪，欧洲国家种植的茄子都是白色或奶黄色的圆形品种。因为看起来很像鸡或鹅蛋，所以现在美国、加拿大等国家都称茄子为eggplant。

Aubergine这个名字源自法文albergina是eggplant的意思。至于brinjal，这个名字在印度较为普遍。Aubergine和brinjal多为紫色或紫黑色，所以Aubergine可称为aubergine eggplant或color eggplant。

Vacation? Vocation?

根据Merriam-Webster Word Central (http://www.wordcentral.com/),

“vocation” 可解作：career 或occupation
1 : a strong desire or leaning for a certain career or course of action; especially : a divine call to the religious life
2 a : the work a person regularly does : OCCUPATION b : the persons in a particular occupation

“vacation” 可解作：假期
1 : a period during which activity (as of a school) is stopped for a time
2 : a period spent away from home or business in travel or amusement

学巴主人是希望学子们将会有个难忘的将来（事业）抑或希望游客有个难忘的假期呢？

烟花

璀璨美丽的烟火也称谓烟花或焰火。
在古时候，烟火主要用于军事上或盛大的典礼中。
现在，除了跨年倒数活动外，各民族的重大节庆时也看得到璀丽的烟火。

烟花的结构其实和爆竹大同小异。它们都含有火药与药引。烟花点燃后，各种金属粉末在高温燃烧而形成缤纷夺目的色彩。不同的金属有不同的焰色反应，而产生不同颜色的光芒。在制作烟花的过程中加入一些经过巧妙排列，决定燃烧先後次序的各类金属粉末便能够使烟花燃放时绽放出五彩缤纷的图案了。

这是之前找到的一些金属焰色反应例子：

钠 (Na) -> 黄;

锂 (Li) -> 紫红;

钾 (K) -> 浅紫;

铷 (Rb) -> 紫;

铯 (Cs) -> 紫红;

钙 (Ca) -> 砖红色;

锶 (Sr) -> 洋红;

铜 (Cu) -> 绿;

钡 (Ba) -> 黄绿

Kilo? kilo?

Kilo is one of the prefix multipliers that is used to quantify things in computing and telecommunications ,bytes or bits, or electronics or physics, for example ohm or Hz. Each prefix multiplier consists of a one-letter abbreviation and the prefix that it stands for. Kilo is represented by the letter K or k.

Sometimes we see kilo represented by a upper case K, Kbytes or Kbits; sometimes its in lower case, kHz. Should it be always upper case or always lower case?

In communications, electronics, and physics, the prefix multipliers are defined in powers of 10 such as frequency, kHz, data speed, kbps, and resistance value, kΩ. For IT and data storage, the prefix multipliers are mostly defined in powers of 2 such as KB (KByte).
