Unfolding the Earth – Myriahedral projections

Unfolding the Earth - Myriahedral projectionsHow can we unfold the Earth? Making a map of the earth is an ancient problem. For thousands of years cartographers, mathematicians, and inventors have developed methods to flatten the curved surface of the earth into a 2D plane. The main problem is that you cannot do this perfectly, such that both the shape and size of the surface are depicted properly everywhere, hence the result is never neutral.

Visualization professor Jack van Wijk developed a new method of unfolding the earth: Myriahedral projections. The idea is take a map of a small part of the earth, which is almost perfect, glue neighboring maps to it, and repeat this until the whole earth is shown. Of course you get interrupts, but does this matter?

This is news?!?!?! Buckminster Fuller did much better projections and solved this problem back in the 1940's what's the news?

Impressive studies! Great artwork! The question that immediately arises is: "Why would we need to 'represent the Earth as flat'?"
Of course Google Earth is not free from distortion at all, but by putting a map (or layered maps) in spherical 3D representation, it manages to create an informative model that stays as close to the original shape as possible, no?

Should men be able to give birth to children?


Lisa Mandemaker: Using an artificial womb could lead to more equality between sexes, but also between different family layouts. If men would be able to give birth to children, it would maybe be easier for male same-sex couples to have a child together.
