1 . The United Kingdom is hosting the AI Safety Summit, bringing politicians, computer scientists and big AI company leaders to a site chosen for its symbolism: Bletchley Park, the birthplace of computing and code-breaking (密码破译).
During World War II, a group of mathematicians, chess masters and other experts gathered at the Victorian country house 72 kilometers northwest of London to start a secret war against Nazi Germany. Their goal was to break a set of constantly changing codes produced by Nazi Germany’s Enigma machine. To do it, Bletchley Park’s wartime scientists — building on work done by Polish code-breakers — developed Colossus, the first programmable digital computer. Some historians say cracking the code helped shorten the war by up to two years.
“It has oversimplified its true contribution by describing Bletchley Park as a playground for Turing and other scientists.” said historian Chris Smith, author of The Hidden History of Bletchley Park. “Although it fits into the romantic idea that a group of smart men with a bit of wool and some yards of wire can win the war. In fact, almost 10,000 people worked at Bletchley Park during the war. Three quarters of them were women. It’s basically a factory... Twenty-four hours a day, seven days a week. When peace came, the code-breakers returned to civilian life and promised to keep secret about their wartime work. It was not until the 1970s that the work at Bletchley Park became widely known in Britain.”
In 1994, the site opened as a museum, after local historians banded together to prevent it from being pulled down to build a supermarket. It was restored to its 1940s appearance, complete with old typewriters, phones and cups—including the one tied to a heater in Hut 8, where Turing led the Enigma team.

4 . Gettysburg National Military Park was established in 1895, 32 years after the deadly battle. Gettysburg is the most-visited of the Civil War battlefields.
Many visitors start their visit at the Gettysburg Museum of the Civil War. The museum has the world’s largest collection of Civil War objects. The museum has more than 1 million items, from soldiers’ private notebooks and uniforms to original maps of the battlefield. The museum also houses the Gettysburg cyclorama (风景画幕) painting, showing the final attack in the Battle of Gettysburg: Pickett’s Charge. George Pickett was a Confederate general. On July 3, 1863, he led a charge against stronger Union forces. It was a disaster for the Confederate soldiers.
French artist Paul Phillippoteaux and a team of 20 artists created the painting in the 1880s. Phillippoteaux and his team visited the battlefield. It took more than one year for the huge painting to be complete. The cyclorama is 114 metres long and almost 13 metres tall. It has long been one of the most popular parts of the Gettysburg experience. But by the 1990s, the painting was in poor condition. Experts warned that if the cyclorama was not repaired, the painting could be lost.
A restoration project began in 2003. The painting was cleaned and separated into its 14 parts, and later moved into the new centre. There, the original canvas (帆布) was sewn onto new cloth made in China. Park service officials say China was one of the few countries able to produce cloth in the sizes needed. Then each part was hung and sewn together.
A team of cyclorama experts from Poland worked on the project in Gettysburg. The repair work of the Gettysburg Cyclorama marked one of the largest art conservation effort ever in North America.
After the museum, tourists can visit the Soldiers’ National Cemetery, where many of the Union soldiers who died during the Battle of Gettysburg are buried. The cemetery was dedicated on November 19, 1863, the same day President Lincoln gave his “Gettysburg Address”. Historians agree that Lincoln’s Gettysburg Address defined Americans as a people who believed in freedom, democracy and equality.

10 . This year, the world celebrates a century of Disney magic, starting from a small animation studio to one of the most influential entertainment (娱乐) companies in the world.
In 1923, the Disney Brothers Studio was founded in California by Walter Disney and his brother Roy. In 1928, Disney launched his most symbolic creation, Mickey Mouse, with the release of Steamboat Willie. With his big round ears and cheerful personality, Mickey quickly became an instant hit.
Disney’s dream extended beyond the world of animation, however. In 1955, Disneyland, the first theme park in the world, opened its doors in California. This sparked the creation of several more Disneyland parks worldwide.
