Highway through a building

The Japanese engineers found an ingenious way to make the best use of the available space when they built the exit of the Hanshin Highway through the Gate Tower building in Fukushima-ku, Osaka. The exit passes between the fifth and seventh floors of the building. The elevators pass through these floors without stopping. There is a structure that surrounds the part of the highway passing through the building to protect the building from noise.

Invention of dynamite

Alfred Nobel was a Swedish industrialist, engineer and inventor. He was into construction and that led him to perform an experiment to find out ways of blasting rocks. His research led him to nitroglycerine. He found out that mixing silica with nitroglycerine would make it easy to handle. This mixture is known today as dynamite.
