Pj and I looked at a map of the world. This map displayed the population densities of the world.

We discussed pockets of population displayed on the map and the reasons for those specific pockets. We discussed the Southeast corner of Australia, and the long narrow strip of population in Egypt.

PJ told me about an ancestor of his who invented an improved water pump. Together, we looked at the patent on file on with the USPTO for said pump. We were able to see where he filed his patent and the date of the filing. We were able to see the art submitted with it as well.

We discussed how technology can influence human populations as well. PJ was asked to surmise how an improved water pump may influence where humans can live on the Earth.

PJ had some wonderful insights and I enjoyed discussing these topics with him.
