Almost every machine with moving parts has wheels, yet no one knows exactly when the first wheel was invented or what it was used for. We do know, however, that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia. It is over 5,100 years old. Evidence suggests that wheels for transport didn't become popular for a while, though. This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation. While wheels need to roll on smooth surfaces, roads with smooth surfaces weren't going to be constructed until there was plenty of demand for them. Eventually, road surfaces did become smoother, but this difficult situation appeared again a few centuries later. There had been no important changes in wheel and vehicle design before the arrival of modem road design.
In the mid-1700s, a Frenchman came up with a new design of road—a base layer (层) of large stones covered with a thin layer of smaller stones. A Scotsman improved on this design in the 1820s and a strong, lasting road surface became a reality. At around the same time, metal hubs (the central part of a wheel) came into being, followed by the pneumatic tyre (充气轮胎) in 1846. Alloy wheels were invented in 1967, sixty years after the appearance of tarmacked roads (柏油路). As wheel design took off, vehicles got faster and faster.
Welcome to the online Macmillan Dictionary of the BUZZWORD of the month. Word entry-JOMO JOMO is an acronym (首字母缩略词) standing for the expression , and is simply refers to the gratifying feeling you get when you break away from the(real or virtual)activities of your social group and spend time doing exactly what you most want to do. JOMO is often described as a resist against the hyper-connected society we live in, where technology pushes both social and professional activity constantly in our faces, so that it's virtually impossible to be happily unaware of what everyone else is doing. This often forces us into spending time in ways which we wouldn't necessarily have chosen. JOMO then, is about stepping off the social fashion and reconnecting with what really makes us happy. Background-JOMO The concept of JOMO first appeared in 2012, its early use often credited to blogger Anil Dash who, having to withdraw from both on-and offline activity for a period after the birth of his son. realized that he'd enjoyed himself greatly and didn't feel he'd missed out on anything at all. JOMO is a play on the earlier acronym FOMO, meaning "fear of missing out", which is used to describe the feeling of anxiety that people experience when they discover, often via social media, that they've let go on a social event or other positive experience. The existence of expressions like JOMO suggest that, although we're unlikely to resist technology completely, the more deeply we immerse(沉浸)in it, the more we're beginning to evaluate its hold on us. Other newly created combined words reflecting this zeitgeist include ringxiety. the constant need to check your phone or mistakenly thinking it's ringing. nhubbing, the related condition of being impolite in social situations by checking your phone, tablet, etc., and infobesity, continuous addiction to digital information in which affects your ability to concentrate. |
