We know about cases in the US where citizens have looked at the register, taken a gun and shot the person on the list. I don't want that to happen in Germany.

In a case like this there are always calls for us to introduce something new, and people say everything we had up to this point is insufficient.

The only question is: are the files held by the police -- which are partly accessible to all police forces across Germany -- fully up-to-date with all information. If that is the case, the problem has already been solved.

We have a tool in place to develop the product of the future. It could enable us, in the very far future, to be able to build computer devices on an atomic scale.

We will then need alternative structures, and perhaps altogether different ways of computing. Techniques like this can help us gain the knowledge needed to create those alternatives.

The acquisition allows us to tap into the growth potential of the construction chemicals market on a sustainable basis and will further expand our position in this high-yield industry.
