This rectangular world map [from the design firm AuthaGraph] is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining areas proportions and unfolding it to be a rectangle.

The world map can be tiled in any directions without visible seams. From this map-tiling, a new world map with triangular, rectangular or parallelogram’s outline can be framed out with various regions at its center.

As we struggle to keep it all in proportion, we might send exploratory birthday greetings to Fabian Gottlieb Thaddeus von Bellingshausen; he was born on this date in 1778.  A sailor, navigator, and cartographer, Bellingshausen was appointed by Czar Alexander I of Russia to lead an expedition that aimed to pick up where Captain Cook (who had died a year after Bellingshausen’s birth) left off, exploring the southern polar region of the globe.  Bellinghausen may have been the first to sight the Antarctic mainland, when he saw distant mountains on January 28, 1820.  Between February 17-19, he recorded seeing ice cliffs and ice-covered mountains, though he didn’t realize that they were in fact a continental mainland.  Similar sightings were also made at about the same time British naval captain Edward Bransfield and the American sealing captain Nathaniel Palmer sailing from other directions, so who was actually the first of them to see Antarctica remains unclear.

(Just as there is some uncertainty as to which of the three mariners was in fact the first to sight the seventh continent, so there is some confusion as to Bellingshausen’s birth date.  This is one of the primary candidates.)

On a dry lake bed in Nevada, a group of friends build the first scale model of the solar system with complete planetary orbits: a true illustration of our place in the universe…

As we reach for the stars, we might recall that it was on this date in 1988 that NASA launched the space shuttle Discovery, marking America’s resumption of manned space flight following the 1986 Challenger disaster.  It was the first of Discovery‘s two “Return To Flight” assignments; it flew the “twin” missions in 2005 and 2006 that followed the Columbia disaster in 2003.

I said “pinHOLE,” not “pinhead”…

Today is Worldwide Pinhole Photography Day— a global celebration of lens-less photography.

As we relax because we don’t have to worry about focusing, we might recall that it was on this date in 1990 that the (current) “mother of all cameras,” the Hubble Space Telescope, went into orbit, deployed by the crew of the Space Shuttle Discovery (which had lifted off the day before).
