8. 5 The name was inspired by a puzzle question that Vincent Connare heard within Microsoft headquarters. The question was "can you make a X that could launch a person from main campus to the new consumer campus about a mile away? Mathematically, is it possible and how?" and Mr. Connare "thought that would be a great name for a font that launches words across the Internet".

12. 9 X is an autonomous organization set up in 1988 under the Department of Science & Technology to look ahead in technologies, assess the technology trajectories, and support technology innovation by network actions in select technology areas of national importance. In 1993, X embarked upon the major task of formulating a Technology Vision for the country in various emerging technology areas. The outcome of the Technology Vision 2020 exercise led to the set of 17 documents, including sixteen technology areas and one on services. The effort was a unique and pioneering exercise that involved more than 5,000 experts including scientists, technologists and corporate managers from academia, industry and the government. X continues to strive for technology development of the country by leveraging technology innovation through sustained and concerted programmes in close association with academia and industry. 11

13. 10 X works a bit like taking a flash-lit photo of an object using a normal camera. There the image forms from photons that come out of the flash, bounce off an object and into the lens. The new technique also uses a light source to illuminate an object. However, the image is not formed from light that hits the object and bounces back. Instead, the camera collects photons that do not hit the object, but are paired through a quantum effect with others that did. The same method could one day be employed to produce satellite images of objects hidden behind clouds or smoke, using the sun's radiation as the photon source. Doing that may require a photon counter beneath the clouds, but could allow a top-down view not possible using conventional methods. 12

20. Microsoft Comic Chat, or simply Microsoft Chat It is a graphical IRC client created by Microsoft, first released with Internet Explorer 3.0 in 1996. It was developed by Microsoft researcher David Kurlander, with Microsoft research's virtual worlds group and later a group he managed in Microsoft's internet division. Its main feature, which set it apart from other IRC clients, is that it enabled comic characters to represent a user; this character could express a specified emotion, possibly making IRC chatting a more emotive and expressive experience. All of the characters and backgrounds were initially created by comic artist Jim Woodring. Later, available tools allowed user-created characters and backgrounds. 18
