1 . About 12,000 years ago — long before the famous Roswell UFO crash made headlines in America — an alien (外星人的) spaceship crashed in China. And their descendants are still living in a faraway Chinese village today! That is the mind-bending claim made in the new book Out of Time and Place, a collection of reports from the files of Fate, a magazine edited by Terry O’Neill.

The story first came to light in 1937 when an expedition led by Chi Pu-Tei came across a group of caves deep in the Bayan-Kara-Ula Mountains. In the caves were found strange-looking skeletons with big heads and small, slender bodies —closely matching typical descriptions of space aliens. The explorers also uncovered 716 mysterious stone discs with strange hieroglyphics (象形文字) on them.

In Qinghai province, where the mountains lie, ancient stories tell of small, skinny beings with oversize heads who came from the sky long long ago. And to this day, locals live in fear of attack from strange-looking creatures from above.

And there’s more. In 1947, British scientist Karyl Robin-Evans led an expedition into the mountains and discovered a group of dwarfs (侏儒) who called themselves the Droza. “They told him that their ancestors came from a planet in the Sirius (天狼星) system and crashed in this mountain area a long time ago,” writes Hausdorf, “Many of them were killed, but survivors adapted themselves to living on this rough planet far from home.”

For decades, Robin-Evans’ claims were dismissed as nonsense. But in 1995, the Associated Press reported that in the region a village named Huilong had been recently discovered — populated by 120 dwarfs ranging from 3-foot-10 to 2-foot-1 tall. Hausdorf asks, “Could these people be the last living descendants of the survivors of the legendary UFO crash — the Chinese Roswell?”

2 . Hell comes to Pearl Harbor

It was Sunday, December 7,1941. As usual, the wake­up call came at 5:45 a.m. The men aboard the warship USS Arizona stretched and rubbed their eyes. Seaman Russell Warriner was awakened by Quartermaster Louis Conter. Russell made his bed and helped clean the huge, shared room. The men went to the washroom, dressed in their uniforms and sat down to breakfast. It looked like it would be a normal day on board the ship.

But nobody ate their breakfast: at that moment, there was a huge crashing sound from above. The ship shook violently and the men looked at each other in horror. Above their heads, hundreds of Japanese planes circled like eagles. They were diving down to drop bombs on Pearl Harbor. The scream of their engines was deafening. As bombs thundered all around, clouds of black smoke rose into the sky and hung over the sea. Russell felt his blood freeze, but he quickly came to himself and rushed up to the deck. Moments later, a bomb hit the USS Arizona and Russell was thrown more than 100 meters across the ship. He suffered serious burns on his hands, arms and legs, and watched many of his friends die.

Louis, meanwhile, also standing on the deck, was lucky not to be thrown into the sea. With only minor injuries, he was able to help others who were severely burnt and in terrible pain. After receiving the order to abandon ship, Louis saved more men from the water, dragging them into the lifeboat. In the chaos and confusion after the attack, the US Navy sent a message to his family that Louis had been killed in the attack. Luckily, he was able to get in touch with them before the message arrived. Despite his remarkable actions, Louis did not think that he was a hero. “The heroes are the ones that gave their lives that day,” he said.

Russell was saved from the water, but he was badly burnt, bleeding heavily. Fortunately, he was taken to hospital and survived. For many years, Russell refused to talk about what happened that morning, describing it simply as “hell”. His wife Elsa said, “When he opened up later on, he always mentioned the horror of it.”

Louis and Russell would never forget the terrible scene of the attack, but they were fortunate enough to be among the few survivors from the Arizona. Nobody had expected the bombing. Japan had hatched a plot to launch a surprise attack on Pearl Harbor, so the attack began without warning and without declaring war on the United States. The attack destroyed nearly 20 American ships and over 180 airplanes. In total, more than 2,000 American people were killed and over 1,000 others were wounded that day. More than 1,000 people aboard the Arizona lost their lives. Out of 37 sets of brothers, Russell and his brother were the only full pair to survive the attack．

The surprise attack came as a great shock to the whole nation. The next day, President Roosevelt delivered his famous Pearl Harbor Speech, in which he described December 7 as “a date which will live in infamy” and asked that the US Congress declare war on Japan. In response to the attack and the president’s address, the United States joined the Second World War.

Today, the USS Arizona lies where it sank: in the middle of the Pacific Ocean. Its location is marked with a memorial shaped like a bridge, which crosses the ship’s sunken remains . Each year, more than two million people visit the memorial. They come to see the shadow of the ship at the bottom of Pearl Harbor, to learn about the attack, to show respect for those who had lost their lives in the attack and to pray for world peace. Although about eight decades has passed, the attack on Pearl Harbor, one of the darkest episodes in American history, will never be forgotten.

3 . Anxiety sweat. Horsehair Wet grass and soil after a rain. Gunpowder. Perfume （香水） containing rosemary and bitter orange. A touch of leather.

This might have been what Napoleon's withdrawal from the Battle of Waterloo in 1815 smelled like. At least, these are some of the elements that Caro Verbeek, an art historian and olfactory（嗅觉的）researcher, tried to combine when she was reconstructing the smell. “Wars are extremely smelly,” Dr. Verbeek said. “Soldiers don't write about their injuries as much as they write about the terrible sounds and smells. So we know more about them. We also know that it had rained the night before the battle, that anxiety sweat smells different from normal sweat, and that there were thousands of horses on the field.” These were some details Dr. Verbeek relied on during the reconstruction, which is part of a project called “In Search of Lost Scents（气味）.” The scent is offered in the Rijks museum as part of tours- -on pieces of paper or in a necklace with tiny pumps- alongside Jan Willem Pieneman's 1824 painting of the scene.

Dr. Verbeek approaches past smells by attempting to recreate versions of them, as she did with the Battle of Waterloo, making a perfume of sorts that might be associated with historical events, people and works of art. Bringing smell into a museum context can be one way to make art more accessible. Marie Clapot, associate museum educator, has worked over the last few years to bring smell into the museum “It's not just about ‘Oh, it's nice to smell something.’ It's one way you can make an art objet accessible” It is also a way, she said, to bring a number of people into the conversation about art who might not be moved by traditional art history.
