3 . Hurricanes are large storms that produce winds of 119 kilometers per hour or higher. That’s faster than a cheetah, the fastest animal on land. Hurricanes are not only some of the planet’s most violent storms, but also the costliest natural disasters in the United States, researchers reported in 2019 in the journal PNAS. Ranking (排名) the most damaging hurricanes, however, depends on the measures used: usually, economic cost or lives lost.

Katrina was the most expensive hurricane of all time, causing a huge economic loss when it sabotaged New Orleans and other Gulf Coast areas. The cost was over $186 billion, according to the National Oceanic and Atmospheric Administration (NOAA). Katrina’s losses swallowed 1% of the US GDP, or the total value of goods produced and services provided by a country in one year, according to the PNAS study.

John Nielsen-Gammon, a professor of atmospheric sciences at Texas A & M University, told Live Science that the next costliest hurricane was 2017’s hurricane Harvey, which caused $149 billion of damage, mostly due to rainfall that produced widespread flooding across southeast Texas, including Houston.

“Those two storms top the list for economic damage both worldwide and in the US, which is no accidence,” Nielsen-Gammon added. “The most damaging hurricanes are most likely to occur where you have lots of expensive buildings,” he said. “That’s why two United States hurricanes top the list.”

In 2017, Hurricane Maria caused $107 billion in damage in Puerto Rico, placing it third on NOAA’s list of the costliest US storms. Hurricane Sandy, which flooded New York City’s subway tunnels and other areas in 2012, came next on the list ($82 billion), followed by 2021’s Hurricane Ida, which flooded Louisiana. Developing countries also suffered a lot from hurricanes.

4 . We did a quick survey of New Year traditions around the world, and couldn’t help but notice that the traditions might reflect cultural varieties? but the meanings behind them are pretty universal.

Philippines

In Philippines? families hold traditional dinner parties called Media Noche to greet the New Year. Circle-shaped fruits are their favorites, such as grapes, oranges and melons, since they look like coins, you know. Filipinos actually try to choose 12 different kinds of fruit to put on the table—one for each month in the New Year.

Make sure you leave some food in your plate. It’s bad luck to start the New Year off as a hungry wolf.

Spain

Many Spaniards will eat 12 fresh grapes at midnight—one with each strike of the clock. Each grape represents a wish for happiness and good luck for every month in the coming year. This “12 grapes in 12 seconds“ custom came from a grape farmer in the Alicante region who wanted to promote his produce about a century ago. The tradition has spread to other countries too? with a few adjustments. In Portugal? they eat 12 dried grapes. In Peru? they eat a thirteenth grape.

Denmark

In Denmark_? they eat kransekage, a big horn-shaped cake, on New Year’s Eve. When they’re finished with the cake, it’s Danish custom to throw the used plates against the front doors of their friends and neighbors. It’s actually a sign of friendship.

Italy

Pork sausages are usually served on New Year’s Eve in Italy. Italians choose pork because they think pigs are fat and keep moving forward, while other animals, such as chickens or cows, move backward or stand still.

But whatever you eat into the New Year in Italy-pork, fish or chicken-make sure you stay at home. Italians throw old possessions out of the window after midnight as an out-with-the-old, make-room-for-the-new gesture.

5 . Coding(编码) apps and programming apps for kids are becoming increasingly popular. Here are some of the best apps for teaching kids to code.

Scratch

Scratch is by far the most popular coding app for kids, and it is now used in many schools all over the world. It is available for free on the web as well as for Android and iOS, which is why it is so popular. Created in 2003 by MIT students and staff, its coding language is designed for children aged 7 to 16.

The language employs visual blocks or bricks that can be dragged and dropped on a workspace to construct logical chains. As a result, the child will have a better understanding of the fundamental principles of coding.

Daisy the Dinosaur

Daisy the Dinosaur is a free iPad and iPhone programming app. What distinguishes it from the rest is that it is designed specifically for children aged 4 to 7. The app was developed by the same team that created the Hopscotch coding app for kids. If you’ve ever used that app, Daisy the Dinosaur has a similar user-friendly interface with limited features that is best for beginners.

Cargo-Bot

Cargo-Bot is a free coding app that is available for both Android and iOS devices. It is appropriate for children aged 10 and up. This app specialises in puzzle challenges involving a robotic arm that must be programmed to perform various tasks, most notably moving coloured boxes to create a specific design or pattern.

Kodable

Another relatively well-known coding app for kids is Kodable.’ It is free for: both the iPhone and iPad, but there is no option for Android or the web. Kodable is appropriate for both younger children and older teenagers(from 8 years old and up). It is also remarkable for guiding users from a basic to a complex level of coding.

The approach is very game-like, with users able to select a character to guide them through the levels.

8 . Some libraries use unique architecture to encourage visitors to explore the racks and settle down with a new book, or use flowing libraries to bring books to hard-to-reach populations.

Kansas City Library (Kansas City, Missouri)

Along the south wall of this parking garage’s exterior, visitors are treated to what looks like a huge shelf of books. The building originally served as a bank, which is readily apparent when the library has screenings in its Vault Theater, inside an actual 1925 bank vault.

Stuttgart City Library (Stuttgart, Germany)

Opened in 2011, this nine-story public library designed by Eun Young Yi is characterized by its impressive white-on-white color scheme, its bold cubic shape and its cavernous interior. This cultural center for the city, designed to feel open and full of light, can be entered from any of its four sides, and readers can borrow artwork as well as books.

The Camel Library Service (North Eastern Province, Kenya)

To fight with low literacy rates in the desert of Kenya, the government created a roaming library composed of nine camels to bring books to villages. The library travels four days a week serving the region’s migratory people. Currently the service focuses on children, but with more funding they plan to increase their reach both in distance and the titles they carry.

Macquarie University Library (Sydney, Australia)

A stunning combination of cutting edge and sustainable, this building was made from recycled materials, features a green roof, and was designed to imitate the look of a eucalyptus tree. It is also state of the art, using robot cranes to bring requested books to the front desk.
