...family company with just 80 employees in 1967. In the following years he transformed it into a vast corporate empire of 120 companies that generate revenue of some €30 billion, employ around 100,000 people and range in concerns from generic-drug maker Ratiopharm to Germany's biggest cement maker, HeidelbergCement. An unassuming lawyer, he was Germany's fifth richest individual and 94th on Forbes' list of the world's richest people, with a net worth estimated at nearly €7 billion ($9.2 billion...
...Obama, his wife Michelle and their daughters climbed over a stone wall to get closer to the water. The sun was out and the wind was blowing strongly. More than a dozen people headed over the wall and down the rocky shoreline with them. The ceremony appeared to further cement Obama's emotional ties to Hawaii. "In his heart and in his soul he is a child of Hawaii," says Andy Winer, the state Director for the Obama campaign. "This is where his roots are and where his values come from...

"I wouldn't cement this year's record. It's one of those things that will get broken in the next year or so," says Van Gundy. "I don't think anyone cares about how the coaches are treated."

Stronger concrete translates into significant gains for the environment because it can be applied more thinly, consuming considerably fewer raw materials than regular concrete. (The basic mixture includes cement, stone or other aggregate and water.) Moreover, concrete has some properties that make it intrinsically energy-efficient when used in buildings. It insulates well because it's poured and thus doesn't let in wind and water. Its density also means that it stores heat during the day and releases it at night, making it possible to save on air-conditioning and heating. Architects including Ferrier are playing with such possibilities...
Lafarge is by no means alone. Franz-Josef Ulm, a professor of civil and environmental engineering at Massachusetts Institute of Technology and a concrete expert, says "there's not one single cement company that is not looking at" ways to improve the resistance of concrete. He still sees room for improvement. The next step is to create materials with higher strength but that use the same amount of initial material, says...
