If you imagine all of the constellations in the sky together as a single sphere, if you imagine the entire tapestry of stars as a unified spherical map surrounding us and sign-posting our view of the universe in every direction, then you will be visualizing a celestial sphere. 'A thin box could hold flat, double-sided maps of all the major planets and moons in the solar system,' Gott said, 'or a stack of Earth maps giving physical data, political boundaries, population density, climate, languages, explorers' voyages, empires at different historical periods or continents at different geological epochs.Maps of outer space for kids to draw on, cut out, assemble, and use as constellation calendars. They also see the design being printed on cardboard or plastic and stacked together like records in a box or slipped into textbooks. The team is excited that their map can be 'printed front-and-back on a single magazine page, ready for the reader to cut out.' African and South America are draped over the edge, like a sheet over a clothesline, but they're continuous.' ![]() 'If you're an ant, you can crawl from one side of this 'phonograph record' to the other,' Gott said. Researchers also note that there are now boundary cuts and to measure dissonances, you simply use a string or measuring tape from one side to the other. This uses 'regular shares glued together back-to-back, which led to the breakthrough idea for the double-sided map' The team pulled the best uses from the Winkel Triple and then added Gott's work on polyhedra, which is a three-dimensional shape with flat faces. Although polyhedral maps have been around since the 1940s, researchers added a twist to it – they enveloped the shapes. ![]() It can display two hemispheres on the sides, allowing the user to simply flip it over to view a different part of the globe. This uses 'regular shares glued together back-to-back, which led to the breakthrough idea for the double-sided map,' the team shared in a statement.Īnd this is when the two-sided, round map was born. The team pulled the best uses from the Winkel Triple and then added Gott's work on polyhedra, which is a three-dimensional shape with flat faces.Īlthough polyhedral maps have been around since the 1940s, researchers added a twist to it – they enveloped the shapes. However, the map still had a 'boundary cut' problem that split the Pacific Ocean in a way that made it seem like there is a larger distance between Hawaii and Asia. The system looked at six ways flap maps can be distorted: local shapes, areas, distances, flexion (bending), skewness (lopsidedness) and boundary cuts (continuity gaps).Īnd the lower the score, the better of a map.įollowing the investigation, the pair found that the Winkel Triple map was the best – it had a score of 4.563. In 2007, Gott and David Goldberg, a professor of physics at Drexel University, created a way to score current maps. Gott, along with two other map experts, set out to create a radical, but more correct way of seeing our world.Īnd the trio spent years working on the design. 'A map that is good at one thing may not be good at depicting other things. 'One can't make everything perfect,' said Gott, who is also a 1973 graduate alumnus of Princeton. ![]()
