I am interested in the strength of the five-pointed star. One of your "ask a scientist" answers suggested that this star was the strongest fortress geometric figure. Where can I go to read more about its history? Was it used to defend cities or castles or is its defensive structure only theoretical?

From a structural point of view ( my field) the triangle is the strongest element. Buckminster Fuller used the triangle for his dome. So , while I see a relation to the star, I think, from the rest of your question that your interest is for toward fortresses. There, more factors are involved, as defensibility etc. Issues beyond my knowledge.

Regarding where to find information, the obvious answer is the Internet. I am finding that while Google is normally my first choice, Yahoo sometimes is a good lead for questions.

To my knowledge, 5 pointed stars were never used in castle designs. (probably due to greatly reduced internal area for storing provisions) The best place I can think to look for that information would be a study of castles and other fortifications. (history, mostly)

As for it being a strong defensive structure, keep in mind that any attempt to assault any area other than the tip of a point exposes attacking forces to defence from two different walls, at radically different angles. Which means the only way to attack the walls of such a castle are to expose oneself to attack from all sides.
