Geometry: Past and Future

Since ancient times geometry has grown in both breadth and depth. Branches of geometry now exist which were not even conceived 75 years ago. This tremendous growth in geometry has created a tension for educators interested in the subject. There was no lack of topics competing for attention in the classroom at all levels 75 years ago. Now there are even more topic choices, new modes of teaching, and new technologies with which to deliver both new and old ideas alike.
