Airy Points are used for precision measurement (metrology) to support a length standard in such a way as to minimise bending or droop. The points are symmetrically arranged around the centre of the length standard and are separated by a distance equal to 5/9ths of the total length of the measuring device.

Airy Points are normally identified by inscribed marks or lines. For example, a 450mm length gauge would have an Airy Point separation of 450mm times 5/9 = 250mm. A line or pair of lines would be marked onto the gauge 100mm in from each end. Supporting the artefact at these points ensures that the calibrated length is preserved.

If the length gauge is not supported at the Airy Points, the measurement uncertainty is increased.

Roaring 20

The Roaring 20 is a coed a cappella group at Princeton University consisting of 12 to 20 undergraduate students. Founded in 1983, the Roaring 20 was originally an all-male a cappella group that sang jazz from the 1920's. In 1984, the group became coed and began to sing a wider variety of music. Currently, the group maintains a highly diverse repertoire, ranging from Irving Berlin and George Gershwin to George Michael to Radiohead and Ben Folds Five. The group is self-directed and arranges all of its own music.

At Princeton, the Roaring 20 is part of a biweekly arch-rotation that also includes the Katzenjammers, the Nassoons, the Tigertones, The Princeton Footnotes, the Tigressions, the Tigerlilies, and the Wildcats. These groups perform in the gothic arches of Princeton campus, most notably Blair arch.

Besides performing on the Princeton campus, the Roaring 20 has toured extensively around the country and around the globe. Recent tours have taken them to the Dominican Republic, Paris, the Virgin Islands, San Francisco, Montreal, and Italy. The group has entertained audiences at hospitals, schools, alumni gatherings, private parties, cruise ships, weddings corporate functions, and the set of ‘The Price Is Right’.
