Its also a part of Korean history. Experts believe that people began making kimchi around the seventh century. The farming communities created kimchi to provide vegetables all year round. At that time, however, kimchi was just a salted vegetable. It was not until five centuries later that people started adding tasty seeds and other plants. And it was not until the eighteenth century that people began adding the hot red pepper (辣椒). This gave kimchi the red colour that it often has today. The nineteenth century saw the introduction of the Chinese cabbage to Korea. Koreans then started to use this vegetable to make kimchi. And they developed the kimchi that people know and love today. Kimchi is such an important part of Korean culture that there is a yearly kimchi event. It happens every year in October and lasts for several days. People travel from all over South Korea to the event in the city of Gwangju. At the event, different types of kimchi are made to see which one tastes best, and many food products are on show. Besides, there is beautiful traditional music. If you want to learn more about kimchis culture and history, come to visit the Kimchi Field Museum in Seoul. It was started by a large food company in 1986. In the museum, historians have documented almost 200 different kinds of kimchi. In April, 2008, Yi So-Yeon became South Koreas first person to go into space. The 29-year-old took kimchi with her and spent ten days in space. There, she performed a series of science tests. It was such an unusual trip for all Koreans!21.

Now there is something that comes pretty close. Meet the iBill, a piece of plastic about the size of a large cigarette lighter. Equipped with one AAA battery, a couple of buttons and a speaker, the iBill is designed to be simple. A narrow opening allows for a U.S. bill to be placed inside and upon scanning, it will say the amount the bill is worth. However, even though the iBill can do that job for you, it doesnt mean itll tell you if a bill is real or even how much you have. Created by Orbit Research, it will be the first money reader distributed by the U.S. Bureau of Engraving and Printing (BEP). The bureau will soon be shipping iBills, free of charge, across the country. “It is my No. 1 choice,” Cotton says of the iBill, especially when it comes to sorting money as fast as possible. There are actually a bunch of apps (应用程序) that can do what the iBill can, made convenient by the iPhones voiceover functions. In particular, EyeNote was also developed by the U.S. BEP to help distinguish bills. Another app, called LookTel, offers recognition for a large number of countries bills and VisionHunt distinguishes different kinds of bills and offers many tools to the blind. “But a lot of blind people cant afford an iPhone,” says Shawn Callaway, president of the National Federation of the Blind of Washington, D.C.24.
