This is a garbage article. I’m sure the research has some merit but it is not explained here. What do they even mean by saying when you look at a manhole cover from a few feet away you see it as circular instead of an ellipse? I see an ellipse. It doesn’t get transformed into a circle. What on earth are they on about?
- fjdjsmsm 6y agoI believe what they mean is that you know the manhole is a circular object seen at an angle, rather than an ellipse shaped hole.
