... The formation of multiple images of a distant quasar by the gravitational lensing effect of a foreground galaxy may be very simply, and faithfully, accounted for by a wine glass experiment. Figure 1. In the wine glass experiment, a bright compact light source (at the top of the photo) serves as a distant quasar. The wine glass on the table distorts the light rays from the "quasar" and produces a caustic having with a triangular shape (see enlargement in Figure 3 ). ...

... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...

... On May 26 & 27, 1998, about 50 participants met for the workshop ``NICMOS and the VLT'' in Pula, Sardinia, Italy. ... The workshop took place at a time when the expected remaining lifetime of NICMOS was about 7 months, and the first call for proposals for VLT was about 3 month away. The timeliness of the workshop was underlined by the fact that first light for the VLT occurred in the midst of this meeting, which has not been anticipated at the time the date for the workshop was set. ...
