Crew members ran for their lives when overhanging metalwork crashed onto a stage in a Toronto park Saturday afternoon, pinning and killing one man, authorities said. The collapse happened around 4 p.m., one hour before spectators were set to begin streaming in for a concert by the alternative rock group Radiohead. Several people were on the stage at the time, preparing for the show, when scaffolding-like material towering about 50 feet above collapsed. "Unfortunately, four people were hurt," Toronto police Constable Tony Vella said. "The remainder of the people, when they heard the stage coming (down), ran from the area." Firefighters arrived to find one man "trapped under the structure," said Toronto fire Platoon Chief Tony Bellavance. They helped to extricate the man, then moved away from what was then still considered an "unstable structure," Bellavance added. Paramedics, who happened to be at the scene in preparation for the concert, "immediately rendered aid," according to on-site Toronto Emergency Medical Services commander Peter Rotolo. The victim -- who has not been identified, amid efforts to contact his next of kin -- was pronounced dead at the scene. Police said he was in his 30s. Another man who suffered serious injuries due to the collapse was transported to Toronto's Sunnybrook Hospital, Ian McClelland of the city's EMS department said. The 45-year-old man suffered a head injury that isn't considered life-threatening, according to Toronto police. Two other men with minor injuries were assessed and released, McClelland said. Aerial footage afterward showed that some metal framing -- some of it covered in a blue material -- crumpled on the stage, which was in front of a large grassy area. Some of the scaffolding-like material remained standing, reaching about 50 feet in the sky. The stage was being set up especially for the Radiohead concert, Vella said. At the time it came down, the weather was good with no storm rolling through or significant winds, added fellow police Constable Harrison Ford. <sep>How old was the man who was dead at the scene?<sep>In his 30's

An atom is the very smallest particle that still the elements properties. All the atoms of an element are alike. They are also different from the atoms of all other elements. For example, atoms of gold are always the same. It does not matter if they are found in a gold nugget or a gold ring. All gold atoms have the same structure and properties. For example, all gold atoms contain 79 protons. One of golds unique properties is that it is a great conductor of electricity. Gold is a better conductor of electricity than copper. Gold is more rare and expensive than copper. Copper is used in house wiring. Gold is far too expensive. <sep>How is gold different from copper?<sep>Gold is a better conductor of electricity than copper and more rare and expensive than copper

The judge leaned back in his chair and beckoned to Mr. Andrews. It was finished. Spear was free, and from different parts of the courtroom people were moving toward the door. Their numbers showed that the friends of the young man had been many. Mr. Thorndike felt a certain twinge of disappointment. Even though the result relieved and pleased him, he wished, in bringing it about, he had had some part. He begrudged to Isaacs & Sons the credit of having given Spear his liberty. His morning had been wasted. He had neglected his own interests, and in no way assisted those of Spear. He was moving out of the railed enclosure when Andrews called him by name. "His honor," he said impressively, "wishes to speak to you." The judge leaned over his desk and shook Mr. Thorndike by the hand. Then he made a speech. The speech was about public-spirited citizens who, to the neglect of their own interests, came to assist the ends of justice, and fellow-creatures in misfortune. He purposely spoke in a loud voice, and every one stopped to listen. "The law, Mr. Thorndike, is not vindictive," he said. "It wishes only to be just. Nor can it be swayed by wealth or political or social influences. But when there is good in a man, I, personally, want to know it, and when gentlemen like yourself, of your standing in this city, come here to speak a good word for a man, we would stultify the purpose of justice if we did not listen. I thank you for coming, and I wish more of our citizens were as unselfish and public-spirited." It was all quite absurd and most embarrassing, but inwardly Mr. Thorndike glowed with pleasure. It was a long time since any one had had the audacity to tell him he had done well. <sep>Who did Mr. Thorndike want to help?<sep>Spear
