Firms spend considerable sums of money on marketing, and they continue to do so because marketing works. However, marketing can only work if marketers have a reasonably accurate view of human nature. It is argued that many consumer products and adver

The Large Binocular Telescope consists of two 8.4m telescopes on a common mount. Its current active optics system uses measured mechanical deflections of its optics to compensate for misalignment due to changes in telescope elevation angle and analys

We developed a distortion measurement technique that works in snapshot mode. Distortion information across the full field of view can be captured in a single short exposure. To do this, a Ronchi ruling is placed in the object and image planes of the

We describe the active support system for the 8.4 m LBT primary mirrors and the use of this system to optimize the mirror figure in the lab before installation in the telescope. We figured the mirror, mounted on passive supports, to an accuracy of 18
