I hope this is the right forum to post this question.
Recently a friend of mine visited a European country where he
visited a building which has a curious characteristics: a beam of
sunlight strikes a particular spot inside the building only once in
a year, and only at a particular time of the day. I am hoping the
experts here can explain how this is made possible - since I am not
an expert at all in the sun related mathematics.
Thank you!
