...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...
Noticeably Clearer. Nonetheless, Stroke says, all of the details of the photographed object are contained in the 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...
...think you're a sensitive girl. You're too sensitive. I don't want you to feel sorry for me." I object weakly. She is patronizing me and I, because I want to please, allow her to: She has reversed the color roles and now I am the one who smiles and submits. She continues, oblivious: "You really don't know what it's like to be black. You. couldn't stand it. You couldn't stand it for a week." Now she has something I can't have because I'm the wrong color--the strength that comes from...
Those who object to the war have always done so for three basic reasons, and the Tet offensive helped swell the ranks. The three...
Breathtaking Regularity. Getting a good fix on one of the signals, the astronomers calculated that it came from an object no more than 4,000 miles in diameter-about half the size of the earth-that was no more than a neighborly 200 light-years away. The signals occurred with breathtaking regularity, one every 1.337 seconds. "Our first thought," says Radio Astronomer Martin Ryle, director of the Mullard Observatory, "was that this was another intelligence trying to contact...
