...committed it to people who were prepared to raise this challenge against the Johnson Administration at a time when it seemed to me a lot of other politicians were afraid to come down into the playing field. They were willing to stay up on the mountains and light signal fires and bonfires and dance in the light of the moon. But none of them came down. They weren't even coming in from outside, just throwing a message over the fence...
...then, Prime Minister Sir Seewoosagur Ramgoolam of the Hindu-backed Independence Party hopes to diversify the economy and lure new foreign investment. To avert violence, Britain will also help train and equip Mauritius' police and armed forces. As added protection, a company of the King's Shropshire Light Infantry will remain on the island as long as they are needed. That could be for some time...
...perfectly formed image, Stroke explains, every geometrical point on the photographed object should produce a corresponding point on the film. But existing optical systems, instead of producing points, project tiny spots, each of which consists of alternating light and dark concentric circles, or diffraction patterns. If the optical system is in focus, the circles are small. But if it is out of focus, the circles are large and overlap each other, causing blurring...
...picture. The overlapping of spots, no matter how blurred the image, can be expressed in complex mathematical terms called Fourier transforms. Applying mathematical theory to holography, which also produces interference patterns that can be expressed by Fourier transforms, Stroke set up the optical equivalent of an equation. Using laser light, he made two transparencies -one of the blurred photograph of a microscope, the other of a purposely blurred picture of a spot of light shot by the same camera. Then he produced a hologram by projecting laser light through the blurred light-spot transparency onto unexposed film while simultaneously shining...
...heavy rainfall, which totaled 5.01 inches at Logan Airport and set a new 24 hour record for the Boston area, has had relatively light effect on Harvard. "There has been no appreciable damage to Harvard buildings," a Buildings and Grounds spokesman said...
