``Powers of Ten'' Explorer #1

[intro] [explorer] [puzzlers] [technotes] [credits]

In the distance you can barely discern a dark planet, which (when you place the mouse over the image below) moves against the backdrop of the Milky Way. Zoom in closer by holding down the shift key and dragging the mouse downward. During the days ahead, we will be adding things to see and measure as you zoom in. For example, astronomy students might be measuring the size and distance between planets, geographers might be examining the heights of mountains or the street patterns of cities, and microscopists might be looking at the shape of viruses or the geometry of atoms in various types of metal cluster. In all cases a visceral sense of the geometric relationship between these various pursuits will be at hand. Already you can try characterizing the dark planet's sun and moon, some mountains and a skyscraper, as well as a 3[mm] electron microscope specimen floating in space, waiting for support from a human being sitting on a chair with tweezers in hand. For other clues to what's possible, check out this April 2005 intro chemistry adventure.

/\ [Shift]-Drag Down/Up Also Zooms In/Out /\
Note: The mouse allows you to re-orient and or spin the specimen, while the Shift key plus vertical mouse motion allows zooming in on the model for a closer look. Hitting the Home key allows you to return to the original point of view. You can also move the rotation point in space and in days ahead buttons will be added for leaping from point to point, and for measuring more properties of the field of view.

Puzzlers (stay tuned for more...)

Postscript: This remotely accessible airtrack appears to have been built on a lonely outpost in this same spiral arm of our galaxy, but by who?
