Reducing the deficit to zero, while attractive, does nothing to eliminate the debt.

Debt and Deficit are TWO different things. We reduced the deficit to zero during the Clinton administration during the 90s. But we still had a massive debt.

salve a tutti, vorrei sapere che differenza c'è tra informatica applicata e ingegneria informatica... grazie in anticipo! :)?

In most countries which had electricity up to the 1940s "light bulbs" (note spelling) had tungsten filaments, but there were a few instances of early use of fluorescent tubes and sodium lighting in factories and similar large buildings from the very late 1930s.

I do not know about Germany in particular, but I doubt that it was much different from most European counties and Britain in that respect. Germans certainly were in the forefront of technological development in electrical and other matters.

I grew up in Britain in a small town in the 1950s. In that time at home and in most places including street lights there was only one type of bulb - a standard tungsten bulb. Other types of streert light were on the way in around big cities.
