Visitable extreme physics (xfzx) worlds

The worlds below require recently released (auto-loading) Adobe Atmosphere PlugIns, which initially work only on MS w98+ computers with Internet Explorer and/or Adobe's latest PDF reader. Accessibility will broaden in days ahead. Atmosphere connects the web visitor with virtual locations that others may also be visiting, thus mediating discussion as well. Comments and suggestions are invited as we bring these worlds up to compliance with Atmosphere v1.0 and beyond. In the meantime, also feel free to use these worlds to hang out with your friends.


Note: A wide variety of Java-based extreme physics worlds are also available at this site, based on both LiveGraphics3D and Jmol applets.

stuff we have in development...

FastTrak (PDF): High speed air track simulations here offer clues to relativistically-informed patterns of thought (e.g. local rather than global time), as well as data for non-trivial experimentation involving motion at any speed.

St. Louis NanoWorlds Lounge: A place to hang out and discuss recent snapshots brought back by nanoworld adventurers in the region.

NanoWorld WebLab: This is the web version of our Brobdingnagian MetroLink to Lilliput: a jumping off point to a variety of extreme physics adventures on distance and/or time scales different than our own. Note: Javascript is still being upgraded.

MilliWorld: Imagine that you've been shrunk to a height of only two centimeters. What do some items from everyday life look like now?

Four Player Chess: Check out the tiny four player chess board under development on the specimen table in our high resolution TEM lab. Caution: The current implementation takes a while to load, even on a fast system, and may still not allow you to move the pieces.

TEM Dive: This offers the visitor a fantastic voyage down the column of a transmission electron microscope, as though they were only 200 microns in height, and able to freeze electrons in their tracks to boot. Note: Javascript is still not back up.

GSI Silicon Rogue's Gallery: Swim, as a 200 nanometer high visitor, through the rogue's gallery of extended defects found to hide, on occasion, in the otherwise nearly perfect lattice of gigascale integrated circuit silicon wafers. Caution: Until the Javascript does it automatically, you may have to turn gravity off in your Atmosphere window before you plummet beneath the cloud of defects.

Cubic Crystal Gallery: Here you can explore a number of common cubic lattice structures in direct space, up close and personal.

Taking Charge: Sightsee as an atom (or ion) in world of fellow atoms, along with some moving and fixed charges.
