Albert Hofmann was a Swiss Scientist who was fascinated by nature. This led him to a career in chemistry in which he sought answers to his uncertainties. He worked at Sandoz Laboratories where he nurtured his research work, and there he made a lot of success by working with various plants and changing them into something useful. He became famous when he became the first person to produce lysergic acid diethylamide (LSD) (迷幻药). In addition, he was also the first person to taste it and learn about its hallucinogenic (勾起幻觉的) effects. He was deeply connected to the nature and argued that LSD, besides being useful for psychiatry(精神病学), could also be used to promote awareness of mankind's place in nature. However, he was disappointed that his discovery was being carelessly used as a drug for entertainment. Because of his discovery, LSD fans have fondly called him “The father of LSD”. Besides carrying out his scientific experiments, he also authored numerous books and more than 100 scientific articles. In 2007, he featured in a list of the 100 greatest living geniuses(天才), published by The Telegraph Newspaper.

Childhood & Early Life

    Albert Hofmann was born in Baden, Switzerland, on January 11, 1906. He was the eldest of four children. His father was a poor toolmaker in a factory and they lived in a rented apartment. He spent much of his childhood outdoors, and grew up with a very deep connection with nature.

    He had mind-blowing experiences in childhood, wherein nature was changed in magical ways that he didn't understand. These experiences caused questions in his mind, and chemistry was the scientific field which allowed him to understand them.

    He studied chemistry at Zurich University, and his main interest is the chemistry of plants and animals. At 23, he earned his Ph. D with honors.

    When the sun sets in Hong Kong, the city skyline comes alive. Billboard（广告牌）lights flash, and light up the crowded streets. The colorful lights from the tall buildings are one of the city's main attractions.

    “Oh, my god. The lights are so amazing. We love it. It's so nice.” said one visitor.

    But this appreciation is not shared by everyone in Hong Kong. Lat year then government reported a record number of complaints. The curtains may be drawn. But residents argue the bright light outside is hard to escape. “We receive some complaints about the light pollution. They find it very hard to sleep or they have disturbance from the light outside.”

    Scientists at the University of Hong Kong spent 18 months studying levels of light pollution and collecting more than 5 million measurements. They found Hong Kong one of the world's worst “victims”. The lights pollution condition in Hong Kong was extremely severe. Particular in cities, the night sky brightness, as well as the lights, is a few hundred times over the level of that of a night sky without light pollution. In cities such as Seoul, London, Shanghai and Paris, billboard lighting is under control. And there are punishments for people who go against the law.

    But in Hong Kong, there are no laws. A volunteer regulation called Charter of External Light（户外灯光约章）encourages visitors to switch off between 11 p.m. and 7 p.m. The critics say it's not enough to make a difference. The government says 4800 businessmen have signed up to the Charter so far. And it's satisfied that it's working.

    But not everyone is convinced and some residents are taking upon themselves to act. Zoe Chow led a campaign to have a commercial building switch off their midnight. She won but she believes the lights will eventually turn back on. “I know that the building has signed the Charter of External Light. But it is voluntary, not mandatory（强制的）.

    It seems that in many places storms visit more often. When a storm is coming, most people leave the area as quickly as possible and head for safety. But there are a few people who will get into their cars and go straight for the center of the storm. These people are willing to risk being killed by floods or 100-kilometer-an-hour winds for the excitement of watching the storm close up.

    "Storm chasing" is becoming an increasingly popular hobby, especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.

    Although anyone can do it, storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for storm-chasing vacations during the storm season.

    Even then, storm chasing is not all adventure and excitement. "Storm chasing is 95% driving," says Daniel Lynch, who spends most of his summer storm-chasing. "Sometimes you can sit around for hours waiting for something to happen, and all you get is blue sky and a few light showers."

    However, for storm chasers, it is all worth it. "When you get close to a storm, it is the most exciting sight you will ever see in your life," says Jasper Morley. "Every storm is an example of the power of nature. It is the greatest show on Earth."

    If you have the opportunity to visit some places in New Zealand, then the list below is our recommendation.

    Fiordland National Park

    This park is part of the South Westland World Heritage Area and is New Zealand's largest national park and one of the largest in the world. The scenery in Fiordland is nothing short of extremely beautiful, with steep mountains, wild waterfalls, and abundant rain forests. Being able to come back and forth in its deep bay attracts most of the visitors.

    The area has some of the world's greatest walks including the world famous Milford Track, which was described as the finest walk in the world in the early twentieth century.

    Abel Tasman National Park

    Abel Tasman may be New Zealand's smallest national park, but the attractions are huge. Located in one of New Zealand's sunniest spots, the area also has the best beaches in the country.

    The popular Abel Tasman Walk is a great way to see this park. It takes 3-5 days to complete. Sea taxis are also available and can drop you off at any number of beaches within the park.

    Rotorua

    Accessible from New Zealand's biggest city, Auckland, Rotorua is famous for its volcanic activities. Rotorua is also famous for its plentiful lakes which are great for swimming and fishing. The surrounding area contains plenty of native bushes and some famous walks.

    Rotorua is also the best area in the country to experience and learn about Maori culture.

    Mt Cook National Park

    Mt Cook as well as the surrounding area is an alpine( 高山的) park within the World Heritage listed in South Westland. The biggest peaks in all of Australasia are here. The park doesn't contain many trees or plants due to the altitude. Walks range from a two-hour walk to difficult tracks suitable for experienced mountaineers only.

    A helicopter or plane ride gives visitors excellent views of the mountains with the option of landing at the top of Tasman Glacier, a true permanent snow-covered alpine environment.

    Children are starting on digital devices at ever younger ages, and opinions on the effects of children's digital-media habits are deeply polarised.(两极分化的).

    Jean Twenge, a psychology professor, thinks excessive use of the internet and social media makes children lonely and depressed and poses serious risks to their physical and particularly their mental health, sometimes to the point of driving them to suicide.

    However, Daniel Kardefelt-Winther of the Innocenti research office of Unicef examined various evidence and found less cause for alarm than is often suggested. Most of the studies he examined seem to show that the technology helps children stay in touch with their friends and make new ones.

    The relationship between the use of digital technology and children's mental health, broadly speaking, appears to be u-shaped. Researchers have found that moderate use is beneficial, whereas either no use at all or extreme use could be harmful.

    What worries some experts more is that screens are becoming part of the middle-class armoury(武器) for perpetuating(巩固) social advantage. Children from well-off homes are enrolled in private classes to learn skills like "How to be a YouTuber", which poorer parents cannot afford.

The Aviation Industry Corporation of China (AVIC), China's leading aircraft maker, created the country's first fully solar-powered drone (无人机). The large drone, Qimingxing 50, took off at 5:50 pm on September 3rd, 2022, from an airport in Yulin of Shaanxi Province and stayed in the air for 26 minutes before landing on the same runway. AVIC said that all systems of the unmanned plane functioned well on its first flight.

Powered by six electric motors with solar batteries, the drone is designed to conduct long-time operations in near space. Near space is that part of Earth's atmosphere at altitudes of 20 to 100 kilometers. It is above the top altitudes of commercial airliners but below orbiting satellites.

Qimingxing 50, also called "quasi-satellite", features high operational efficiency and eco-friendliness and will be tasked with high-altitude reconnaissance (侦察), forestry fire monitoring, atmospheric environmental inspection, aerial mapping, communication signal relay and other operations.

"Thanks to its capability to conduct very long endurance flights in near space, the drone can essentially become a substitute for satellites," a Chinese aerospace expert said. Satellite services are not always available due to the limited number of satellites and relatively fixed schedules of overhead passes. In time-sensitive missions, near-space drones can offset these disadvantages, the expert said, noting that satellite services could also be damaged in wartime, so near-space drones could replace them in this occasion.

The successful first flight of the Qimingxing-50 lays a solid foundation for the development of key technologies in the country's new energy field, the composite (复合的) material field, which will enhance China's ability to perform tasks in near space and over far oceans. AVIC will seize the opportunity to increase investment and speed up the development of large solar-powered unmanned aircraft.
