Jim fink review1/3/2024 One of the “grand challenges” facing biologists is predicting the complex three-dimensional structure of proteins. “What is remarkable is that he excels in four distinct areas of engineering: the design of hardware, the development of software, the creation of new and improved systems and the mathematical analyses of these systems,” says Qualcomm vice chairman Andrew Viterbi. Qualcomm is impressed with Bender’s versatility. Movie studios could soon transmit digital versions of their films to theaters using such technologies. He currently leads a project to develop high-speed wireless data access with only the amount of spectrum currently used for a few voice users. Using a protocol called Code Division Multiple Access (CDMA),Bender developed new equipment to take maximum advantage of it, including a sophisticated processing system on a single chip that reduced the mass and cost of cell phones. After completing his doctorate at the University of California, San Diego, he joined Qualcomm and started working on projects to improve the quality of wireless communications. One of the folks at the forefront of the search for bandwidth is Paul Bender. But the revolutionary impact of this wireless world will come only when more bandwidth is available to provide video, Internet and other services. The last decade has seen cell phones and wireless communication blossom from a tool for privileged executives to something close to a necessity for almost everyone. Says former colleague Michael Labriola, now CEO of Invisible Web Publishing: “The ideas that came intuitively to him could literally change the world.” During the group’s first year, it hosted an alliance of computers called the Bovine Cooperative, which won a prize by breaking a form of encryption known as RC5.Beberg left in April to work on Cosm, an open-source distributed computing project. In 1997, he founded a nonprofit group called. In a realm with more commercial significance encryption Beberg’s ideas have already paid off. For example, a search for intelligent life in the universe, is following Beberg’s lead with a distributed computing scheme to analyze radio telescope data. Such “distributed computing” promises greater access to number-crunching power, possibly leading to scientific and technological breakthroughs. Adam Beberg has figured out how to tackle such challenges: Throw the unused time of 10,000 computers at them. Some computational problems, such as defeating today’s commercial encryption, strain even the most powerful machines. MIT materials science professor Robert Rose says enthusiastically that “Yoel’s approach using soft materials which can be processed inexpensively to form conformable reflectors may bring vast new markets into play.” Indeed, Fink is trying to exploit a class of polymers, called block copolymers, to create self-organizing optical components. What’s more, his techniques for building these “perfect mirrors” are so general the devices can be made from a wide range of materials, including polymers. But Fink found a way to layer the dielectric material so that the mirror can reflect this light from all angles other dielectric mirrors can’t. Like other dielectric mirrors, Fink’s devices can be tuned to reflect only certain wavelengths of light with high efficiency. Potential applications range from a flexible light guide for delivering laser light to a specific internal organ, to new devices for optical communications, to coatings for windows that efficiently reflect heat while being transparent.įink’s mirror combines the best property of the everyday metallic mirror–its ability to reflect light from all directions–with those of highly specialized dielectric mirrors, widely used in photonics. The “perfect mirror” Yoel Fink invented last year as a graduate student at MIT could mean radical new ways of directing and manipulating light. It’s an invention that forces you to rethink one of man’s most basic tools: the mirror.
