1 . Can a small group of drones (无人机) guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year? That is the very likely future of applying today’s “eyes in the sky” technology to make sure that the millions of kilometres of rail tracks and infrastructure (基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines. They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved. Costs would be cut and operations would be more efficient (高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems. To perform these tasks, drones for rail don’t need to be flying overhead. Engineers are now working on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.

9 . Do you still remember the scene in the famous movie Titanic, directed by Cameron, where Jack was frozen to death in the icy cold water so that Rose could survive on the floating door alone? It broke many people’s hearts. Two decades later, people are still asking the question, “wasn’t there enough room on the door for both of them?” Cameron once responded by saying it wasn’t a question of room, but buoyancy（浮力）— if both of them had tried to stay on the door, he argued, the whole thing would sink.
But several guys from “Mythbusters”, an Australian-American science entertainment television program, decided to put the theory to the test themselves. They discovered that if Rose had took off her life jacket to the bottom of the door, there would have been enough buoyancy to keep both of them afloat.
“It was an artistic choice, the thing was just big enough to hold her, and not big enough to hold him,” Cameron said. “I think it’s all kind of silly, really, that we’re having this discussion 20 years later. But it does show that the film was effective in making Jack so attractive to the audience that it hurts them to see him die. The film is about death and separation; he had to die.”
Since Jack was doomed to die, Cameron said, it could have happened in a variety of different ways. It’s not about the door not being big enough: that’s just a practical method for his death. “Whether it was that, or whether a chimney（烟囱）fell on him, he was going down,” Cameron said. “It’s called art: things happen for artistic reasons, not for physics reasons.”
