I don’t much like caravans (or camper vans, if you prefer). This is probably because, when driven on twisty UK roads, they tend to attract bad drivers who cling to their back ends and are afraid to overtake the combined length of van+car.
Nonetheless, I am a huge admirer of applied mathematicians. Today’s invention relates these diverse phenomena.
It seems that mathematicians have been trying to find the biggest rigid shape which can pass down a passage with right angle bends in it. A near-perfect solution is shown in pink in the diagram.
Today’s invention is to create caravans which have this shape when viewed from above. This allows them to have the largest possible floor area, whilst also being able to negotiate the right angled corners of one lane of a city road network.
