Edward Fredkin, who regardless of by no means having graduated from school grew to become an influential professor of pc science on the Massachusetts Institute of Technology, a pioneer in synthetic intelligence and a maverick theorist who championed the concept your complete universe may operate like one large pc, died on June 13 in Brookline, Mass. He was 88.
His demise, in a hospital, was confirmed by his son Richard.
Fueled by a seemingly limitless scientific creativeness and a blithe indifference to standard considering, Professor Fredkin charged via an endlessly mutating profession that might seem as mind-warping because the iconoclastic theories that made him a pressure in each pc science and physics.
“Ed Fredkin had more ideas per day than most people have in a month,” Gerald Sussman, a professor of digital engineering and a longtime colleague at M.I.T., stated in a telephone interview. “Most of them were bad, and he would have agreed with me on that. But out of those, there were good ideas, too. So he had more good ideas in a lifetime than most people ever have.”
After serving as a fighter pilot within the Air Force within the early Nineteen Fifties, Professor Fredkin grew to become a famend, if unconventional, scientific thinker. He was a detailed buddy and mental sparring associate of the celebrated physicist Richard Feynman and the pc scientist Marvin Minsky, a trailblazer in synthetic intelligence.
An autodidact who left school after a yr, he nonetheless grew to become a full professor of pc science at M.I.T. at 34. He later taught at Carnegie Mellon University in Pittsburgh and at Boston University.
Not content material to restrict his energies to the ivory tower, Professor Fredkin in 1962 based an organization that constructed programmable movie readers, permitting computer systems to research information captured by cameras, reminiscent of Air Force radar data.
That firm, Information International Incorporated, went public in 1968, bringing him a fortune. With his new wealth he purchased a Caribbean island within the British Virgin Islands, to which he traveled in his Cessna 206 seaplane. The island lacked potable water, so Professor Fredkin developed a reverse-osmosis know-how to desalinate seawater, which he become one other business.
He finally bought the property, Mosquito Island, to the British billionaire Richard Branson for $25 million.
Professor Fredkin’s life was full of paradoxes, so it was solely becoming that he was credited together with his personal. Fredkin’s paradox, as it’s identified, posits that when one is deciding between two choices, the extra related they’re the extra time one spends fretting in regards to the resolution, though the distinction in selecting one or the opposite could also be insignificant. Conversely, when the distinction is extra substantial or significant, one is prone to spend much less time deciding.
As an early researcher in synthetic intelligence a half-century in the past, Professor Fredkin foreshadowed the present debates about hyper-intelligent machines.
“It requires a combination of engineering and science, and we already have the engineering,” he Fredkin stated in a 1977 interview with The New York Times. “In order to produce a machine that thinks better than man, we don’t have to understand everything about man. We still don’t understand feathers, but we can fly.”
As a place to begin, he helped pave the best way for machines to checkmate the Bobby Fischers of the world. A developer of an early processing system for chess, Professor Fredkin in 1980 created the Fredkin Prize, a $100,000 award that he supplied to whoever might develop the primary pc program to win the world chess championship.
In 1997, a workforce of IBM programmers did simply that, taking dwelling the six-figure bounty when their pc, Deep Blue, beat Garry Kasparov, the world chess champion.
“There has never been any doubt in my mind that a computer would ultimately beat a reigning world chess champion,” Professor Fredkin stated on the time. “The question has always been when.”
Edward Fredkin was born on Oct. 2, 1934, in Los Angeles, the youngest of 4 youngsters of immigrants from Russia. His father, Manuel Fredkin, ran a series of radio shops that failed in the course of the Great Depression. His mom, Rose (Spiegel) Fredkin, was a pianist.
Cerebral and socially awkward as a youth, Edward prevented sports activities and college dances, preferring to lose himself in hobbies like constructing rockets, designing fireworks and dismantling and rebuilding previous alarm clocks. “I always got along well with machines,” he advised The Atlantic Monthly in 1988.
After highschool, he enrolled within the California Institute of Technology in Pasadena, the place studied with the Nobel Prize-winning chemist Linus Pauling. Lured by his want to fly, nevertheless, he left college in his sophomore yr to hitch the Air Force.
During the Korean War, he skilled to fly fighter jets. But his prodigious abilities with arithmetic and know-how landed him work on army pc techniques as an alternative of in fight. To additional his training in pc science, the Air Force finally despatched him to M.I.T. Lincoln Laboratory, a wellspring of technological innovation funded by the Pentagon .
It was the beginning of an extended tenure at M.I.T., the place within the Nineteen Sixties he helped develop early variations of a number of entry computer systems as part of a Pentagon-funded program referred to as Project MAC. The program additionally explored machine-aided cognition, an early investigation into synthetic intelligence.
“He was one of the world’s first computer programmers,” Professor Sussman stated.
Professor Fredkin was chosen to direct the undertaking in 1971 and have become a full-time college member shortly thereafter.
As his profession developed, he continued to problem mainstream scientific considering. He made main advances in reversible computing, an esoteric subject combining pc science and thermodynamics.
With a pair of improvements — the billiard-ball pc mannequin, which he developed with Tommaso Toffoli, and the Fredkin Gate — he demonstrated that computation shouldn’t be inherently irreversible. Those advances recommend that computation needn’t eat power by overwriting the intermediate outcomes of a computation, and that it’s theoretically attainable to construct a pc that doesn’t eat power or produce warmth.
But none of his insights stoked extra debate than his well-known theories on digital physics, a distinct segment subject through which he grew to become a number one theorist.
His universe-as-one-giant-computer idea, as described by the creator and science author Robert Wright in The Atlantic Monthly in 1988, is predicated on the concept “information is more fundamental than matter and energy.” Professor Fredkin, Mr. Wright stated, believed that “atoms, electrons and quarks consist ultimately of bits — binary units of information, like those that are the currency of computation in a personal computer or a pocket calculator.”
As Professor Fredkin was quoted as saying in that article, DNA, the elemental constructing block of heredity, is “a good example of digitally encoded information.”
“The information that implies what a creature or a plant is going to be is encoded,” he stated. “It has its representation in the DNA, right? OK, now, there is a process that takes that information and transforms it into the creature.”
Even a creature as strange as a mouse, he concluded, “is a big, complicated informational process.”
Professor Fredkin and his first spouse, Dorothy Fredkin, divorced in 1980. In addition to his son Richard, he’s survived by his spouse, Joycelin; a son, Michael, and two daughters, Sally and Susan, from his first marriage; a brother, Norman; a sister, Joan Entz; six grandchildren; and one great-grandchild.
By the tip of his life, Professor Fredkin’s idea of the universe remained fringe, if intriguing. “Most of the physicists don’t think it’s true,” Professor Sussman stated. “I’m not sure if Fredkin believed it was true, either. But certainly there’s a lot to learn by thinking that way.”
His early views on synthetic intelligence, in contrast, appear extra prescient by the day.
“In the distant future we won’t know what computers are doing, or why,” he advised The Times in 1977. “If two of them converse, they’ll say in a second more than all the words spoken during all the lives of all the people who ever lived on this planet.”
Even so, not like many present doomsayers, he didn’t really feel a way of existential dread. “Once there are clearly intelligent machines,” he stated, “they won’t be interested in stealing our toys or dominating us, any more than they would be interested in dominating chimpanzees or taking nuts away from squirrels.”
