The documentary “A Blank on the Map” is interesting because it shows what happens when two worlds meet. The British explorers in the expedition into New Guinea to meet with the various peoples and groups there, while searching for the group of peple suspected of never having met Europeans before. The explorers brought medicine and sought to identify the groups living in the jungles. They hired locals in the neighboring regions of the “blank on the map” to help guide them, even having one porter call to the seemingly invisible people after more than three walks of going through the “blank” and finding nothing of the group. The interest in the area began when a map maker was trying to make sense of the rivers and hills by studying aerial photographs. The photographs revealed the existence of tribes, and so David Attenborough and his fellow travelers went into the jungle to make contact. The films show them meeting with various natives and the struggle that it is just to communicate with them and find the new peoples they are interested in meeting for the first time. The purpose of the expedition was to meet this new group, and yet the group is not really new in any sense, since it is native to the region.

The application of the methods of natural science to the study of people here is very precise. The travelers take note of landmarks, the rocks in the riverbeds, the width and depth of the streams, the animals that...

The explorers have a very deep and immense knowledge of natural science that helps to keep them alive in this foreign territory, where no Europeans have ever traveled. That is part of the novelty of the experience: they are the first to enter into this region. In an age where satellites fly across the sky, to think that there is still some part of the earth that has not been explored is interesting and exciting to people—and that is really the main reason for the expedition: to take the viewer into a world that has never been shown before, and to bring a set of people who have never been found before to the surface.
The natural science applications of the expedition are put to good purposes: they are used to help the travelers keep track of their whereabouts as well as to provide medicines to the groups who recognize that the explorers are friends who are there to help. The sciences assist them in negotiating with the peoples, using elements of the earth such as salt to trade and make new friends so that they might better reach the objective that they are…
