Skyscrapers

No, our prison is not a sky-scraper but there is a lot we can learn from sky-scrapers. Do you know how difficult it is to build a sky-scraper? Do you know how many calculations have to be made to prevent the building from collapsing? These huge buildings have enormous foundations and become thinner to the top, just like pyramids. This is done as during earthquakes the top of the building is shaking much more heavily than the foundation. To prevent it from falling, the foundation should be stronger than the top. This brings us to the conclusion that a seismograph could work better on a sky-scraper, as vibrations on its top would be stronger. Well, there are no sky-scrapers around, but we have a few beams which we can use to lift the seismograph.
