Sculpture Array Joins Art and Science
Concluding article in a series on some of Fermilab's distinctive buildings, based on ideas for sculptures by founding director Robert Wilson.

Broken Symmetry
|
Rising above the lab's Pine Street entrance is the 50-foot, 21-ton Broken Symmetry, largest of Robert Wilson's creations fusing art and science. The orange and black arches appear symmetrical when viewed from below, but are asymmetrical from other angles.
Wilson's Hyperbolic Obelisk, in the reflecting pond in front of Wilson Hall, is 32 feet tall, made of 23 smaller steel plates, each a quarter-inch thick. The obelisk is also called "Acqua Alle Funi" ("water to the ropes"), from the command shouted when the Egyptian obelisk was raised in St. Peter's Square in Rome in the 16th Century.

Mobius Strip
|
|
The Mobius Strip atop Ramsey Auditorium has 3-by-5-inch pieces of stainless steel welded to an eight-foot diameter tubular form. The 36-foot tall Tractricious, in front of the Industrial Complex, is made of 16 stainless steel outer tubes, scrap cryostat tubes from Tevatron magnets and 16 inner pipes from old well casings.

Cosmological questions
By Martin Rees

|
Astronomers have traditionally been 'users' of physics, but now they are returning the compliment. They can discover new physics by probing much more extreme conditions than could ever be produced in Earth-bound laboratories: neutron stars and supernovae reach exceedingly high densities and temperatures, and cosmic rays have millions of times more energy than can be achieved in the biggest terrestrial accelerator. There are growing links between the sciences of the very large and the very small — between cosmos and microworld. Exhilarating progress has already been made: recent advances in cosmology will provide an epochal chapter when the history of science in this decade is written.
