The finite size This conversation reminded me of a claim made for the Box Tunnel on the Great Western Railway, England. It is said that on one day of the year the sun can shine through the tunnel. It is also said that the day on which this happens is Isambard Kingdom Brunel's birthday. He was the guy that designed and built the tunnel. Is this story apocraphal, or is there some truth in it? Does anyone know?
