Different Map Projections

Upsidedown-Map-Of-The-World-OptimizedAny time you take something as massive and complex as the earth and try to put it down on a flat piece of paper you are going to lose details and create inaccuracies. You also have to make choices about how you represent the information. For example, what goes in the center? What goes at the top of the map? The bottom? Is the most “accurate” map the best map?

Does science ever actually prove anything?

Below is a link to a letter signed by a large number of climate scientists about the reality of climate change. One provocative statement they make in defense of their work and against climate change skeptics is that “There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything.”

This letter caused a stir among other scientists, some of whom wrote and signed another letter making the argument that: “There is no reason to doubt the laws of physics governing acceleration and momentum. These laws are the basis for a large number of industrial operations, transportation and numerous other activities.”

An interesting exchange that gets to the nature of science and scientific knowledge.

Ann Druyan Talks About Science, Religion, Wonder, Awe . . . and Carl Sagan

An interesting essay written by Ann Druyan, Carl Sagan’s widow. Carl Sagan was a famous scientist and creator of the original Cosmos television show.

“It is a great tragedy that science, this wonderful process for finding out what is true, has ceded the spiritual uplift of its central revelations: the vastness of the universe, the immensity of time, the relatedness of all life, and life’s preciousness on our tiny planet.”
