EUROPE is home to a variety of cultural treasures. Lonely Planet, the world's largest travel guide publisher, has offered pairs of cities for culture-hungry but time poor travelers.

    London and Paris

    It takes you about two hours to travel from London to Paris by Eurostar, a high-speed railway service. The two capital cities have been competing in fashion, art and nightlife for decades — but each secretly looks up to the other.

    No one can doubt the grand and impressive beauty of Paris' Louvre Museum, but if you want to save money, you cannot skip the British Museum free to visit. Compared with London, Paris has more outdoor attractions, such as the beautiful green walkway La Promenade Plantee.

    In Paris, you'll see diners linger(逗留) over red wine. While in London, you can try some afternoon tea, eat fish and chips or salted cake.

    Vienna and Bratislava

    Austrian capital Vienna and Slovakia city Bratislava are an hour apart by train. But since they are linked by the Danube River, the best way to travel is by ship. A tour of the two cities is the perfect way to experience everything from 17^th century's Habsburg dynast splendor to sci-fi restaurants.

    Vienna is famous for Mozart and imperial palaces. You can appreciate the perfect blending(融合) of architecture and nature in the grand Scholoss Schonbrunn Palace, and reward yourself with a cup of Vienna coffee, which has made its way to the world's cultural heritage.

    Bratislava is best known for its fine dining—the remarkable UFO restaurant. You can enjoy a meat-filled dinner here in an amazing setting.

    A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

    “It's extremely important for us to think about this as a whole system and not just a bunch of individual components (零件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. “The added difficulty with such a project is that actually none of those components are off the shelf and so we have to make them all on our own,” he said.

    They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of individual components, each of which individually has to perform well, and then has to be matched well to everything it's connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

    Wood says the design offers a new way to study flight mechanics and control at insect- scale. Yet, the power, sensing and computation technologies on board could have much broader applications (应用). “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

    When I was 3 years old, I was found to be deaf in my left ear and have a small problem in my right. Being hard of hearing has been difficult, but I've never lived in a state of self-hating sorrow.

    Imagine being able to shut out all sounds as you lay your head down to sleep by simply rolling over onto one side. That's my reality when I sleep on my “good ear”, and it even makes me feel like a superhero sometimes.

    People call my deaf side my “bad ear”, but when I wear my hearing aid, I have access to a range of features(特征)that some other deaf people don't.

    In cinemas, for example, with one click of a button I can enjoy a whole film as though it were whispered to me from the mouths of the actors.

    Having a hearing aid hasn't always felt good, however.

    On the first day I got my aid, when I was 8, I took it to school for show-and-tell. As I explained how it worked to my classmates, a boy yelled out, “Aren't those for old men?”

    At that moment, I felt different. It took a long time for me to get over that sense of being so unlike my peers(同龄人).

    But it's not just choolkids who can make us deaf and hard-of-hearing people feel like burdens(负担).

    Every video on social media that lacks subtitles, for example, means an entire community of deaf people is unable to enjoy it.

    Completely deaf people are excluded from enjoying many movies too, as subtitles in cinemas are almost impossible to find.

    And with hearing aids costing around $2,500 each, it can be hard for many people to afford to be able to listen to the things that others take for granted.

    As for me, I can listen to music, enjoy films, and catch conversations – I'm lucky.

I'm deaf, but I can still hear everything. I've been blessed with wonderful life experiences.

    Teachers' Day is, interestingly, not celebrated on the same day all over the world. In some countries it is marked by a holiday, in others it is a working day.

    International Teachers' Day is celebrated on October 5. Being held ever since 1994, it is in honor of teachers' organizations worldwide. Its aim is to encourage supports for teachers and to meet the needs of students.

    China In 1939, Teachers' Day was set for August 27, Confucius' birthday. In1951, the celebration was stopped. However, it was founded again in 1985, and the day was changed to September 10.

    India   Teachers' Day is celebrated on September 5 in honour of Dr. Sarvepalli Radhakrishnan, the second president of India, whose birthday falls on that day.

    Russia ― In Russia, Teachers' Day was celebrated on the first Sunday of October between 1965 and 1994. Since 1994, the day is observed on the October 5, just the same day as World Teachers Day.

    The US   In the US, Teachers' Day is non-official holiday. It is celebrated on the Tuesday of the first full week of May. A number of activities are organized in schools to honor teachers. The celebrations can continue for the whole week of May.

    Thailand   In Thailand, National Teachers' Day is celebrated every year on January 16. The first Teachers' Day was held in 1957. The day is a holiday in schools.

Growing up in a suburban neighborhood in the Northeastern United States, the advent of springtime didn't hold much significance for me. While it did bring a week-long respite from school, the focus was more on the vacation aspect than the season itself.

For the children in my community, spring was largely an overlooked period. The year was divided into two primary seasons: winter, which offered the thrill of ice skating, sledding, and constructing snow forts; and summer, which allowed us to fully enjoy the beach located a short distance from my home. Spring and autumn were merely transitional periods, marking the countdown to the more exciting seasons.

It's true that as I matured, spring began to hold a certain charm for me, as suggested by the poetic line, "In the spring a young man's fancy lightly turns to thoughts of love," penned by Alfred Lord Tennyson. However, my fascination was more with the romantic notions associated with the season rather than the season itself.

In essence, spring was not a season I paid much heed to... until my journey to China. After spending roughly three months in Beijing, my first Spring Festival made its presence known in an undeniable way. The sporadic fireworks throughout the day and night were a clear indication, but what truly struck me was the apparent absence of the usual hustle and bustle in the city.

The usual throngs of people, streams of vehicles, and the general city noise seemed to have vanished. This mystery was resolved upon my return to work. My colleagues enlightened me that it is customary for Chinese people to travel, if necessary, to reunite with their families during the Spring Festival. Many residents of Beijing are not originally from the capital.

Furthermore, I was introduced to a fascinating aspect of the Spring Festival that continues to astonish me. Regardless of when the holiday commences, there is an almost instantaneous and perceptible improvement in the weather. Spring truly makes its entrance.

The ancient Chinese ability to devise a system that could consistently and accurately herald the change of seasons, year after year, is beyond my comprehension. Yet, they managed to achieve this remarkable feat.
