Sixty-five presidential historians took part in it and they judged the past forty-two American leaders based on ten qualities of leadership, which include public persuasion, crisis leadership, the management of economy, moral leadership and international relations. The historians also looked at administrative ability, relations with Congress, goal setting and pursuit of equal justice for all. Finally, the experts considered performance based on the historical period in which the president lived. The historians chose Abraham Lincoln as America's greatest president. He had also been named best president in a similar study in 2000. Abraham Lincoln was the only president in American history to lead the nation during the Civil War in the 1860s. He united the nation at last. And he took the first steps that destroyed the institution of slavery in America. Edna Medford is a professor of history at Howard University in Washington, D.C. She was an adviser on this study and the earlier one. She says Abraham Lincoln is seen to represent the values that the nation most honors like truthfulness, moderation and respect for human rights. The historians named America's first president, George Washington, as second on the list of greatest presidents. Franklin D. Roosevelt, Theodore Roosevelt and Harry Truman are next in that order. John F. Kennedy, the country's first Roman Catholic president, is sixth on the list. Like Abraham Lincoln, John F. Kennedy was murdered while in office. Among recent presidents, Ronald Reagan was named the tenth best president. Bill Clinton was rated fifteenth. And the historians rated former president George W. Bush as number thirty-six. His father, George H.W. Bush, did much better. He was rated as number eighteen.

Article: No more batteries,no more chargers and no more wires.This is the future promised by "wireless power".a means of broadcasting electricity through the air to laptops,iPods and other gadgets without the need for cables and sockets . Wireless lighting,audio speakers and digital picture frames are expected to be among the first commercial products exhibited in Las Vegas this week at the International Consumer Electronics Show,the world's biggest gadgets tradeshow. Experts believe this is just the beginning and that eventually wireless electricity could do for battery life what WiFi did for,the Internet.In a world without wires,laptop users in cafes and airport terminals would be inside an "electricity hotspot" and no longer have to delve an awkwardly located socket. "You'd be able to buy.a desk that charged any gadget placed on it, or power any PC you put on top," said James Holland,editor of gadgets website Eleetricpig.co.uk."If each room had wireless power,you'd know that once you walked through the front door your nmbile would start charging up--even while still in your bag or pocket.You'd never need to hunt for the right charger again." Among the companies showcasing the ambitions technology at CES is Power Beam.Its system turns electricity into an invisible laser, then beams it as heat,across the room to a solar cell that conveys it back into dectricity. David Graham,the co-founder of Power Beam,said:"We're going to delete the word 'recharge' from the English dictionary.If your,cell phone is recharging on your desk.all day,you won't be thinking about.it." The Silicon Valley company can currently use a laser to generate about 1.5 watts of power to _ a solar.cell 10 meters away.This, sould be enough to power an electronic speaker or small LED lights,but not enough to operate a laptop,which requires about 30 to 50 watts.However,Graham said that the technology could comfortably be scaled up . Power Beam insists its laser does not lead to a risk to users' health because it is simply moving heat from one place...
