Nobel Prize in Physics Awarded for Breakthroughs in Machine Studying
The 2024 Nobel Prize in Physics was given to John Hopfield and Geoffrey Hinton for growth of methods that laid the inspiration for revolutionary advances in synthetic intelligence
John Hopfield and Geoffrey Hinton received this yr’s Nobel Prize in physics “for foundational discoveries and inventions that enable machine learning with artificial neural networks,” the Nobel Committee publicizes.

The human mind, with its billions of interconnected neurons giving rise to consciousness, is usually thought of essentially the most highly effective and versatile laptop within the recognized universe. But for many years scientists have been in search of to alter that through machine studying approaches that emulate the mind’s adaptive computational prowess. The 2024 Nobel Prize in Physics was awarded on Tuesday to the U.S. scientist John Hopfield and the U.Okay. scientist Geoffrey Hinton, every of whom used the instruments of physics to develop synthetic neural networks that laid the foundations for a lot of of at the moment’s most superior synthetic intelligence (AI) functions.
Reached through phone whereas in California, Hinton instructed the Royal Swedish Academy of Sciences that he was “flabbergasted” to be taught he’d acquired the award. After a long time of effort to advance AI, he’s now one of the vital outstanding advocates for higher safeguards, having stepped down final yr from an influential place at Google to talk extra freely concerning the know-how’s dangers. “[AI] will be comparable with the industrial revolution,” he stated throughout his phone interview. “But instead of exceeding people in physical strength, it’s going to exceed people in intellectual ability. We have no experience of what it’s like to have things smarter than us, and it’s going to be wonderful in many respects… But we also have to worry about a number of possible bad consequences, particularly the threat of these things getting out of control.”
Impressed by the mind’s anatomical construction, synthetic neural networks symbolize neurons with nodes that possess completely different values. These nodes type networks of connections, akin to the mind’s pure neural synapses, which will be made stronger or weaker via coaching on any arbitrary information set. This adaptive response permits the factitious neural community to higher acknowledge patterns inside information and make subsequent predictions for the long run—that’s, to be taught with out being explicitly programmed.

Hopfield, a professor at Princeton College in New Jersey, devised an associative reminiscence—the so-called Hopfield community—that shops and recreates photos and different patterns in information. Hinton, a professor on the College of Toronto, used Hopfield’s methodology in tandem with a unique method, the Boltzmann machine, which excels at sample recognition. Hinton’s methodology can be utilized, for instance, to categorise photos or create new cases of an noticed sample; the method has helped gas the continued explosion of progress in synthetic intelligence that’s reworking myriad sectors of human endeavor. Each Hopfield and Hinton started their pioneering work within the Eighties.
“This year’s physics laureates’ breakthroughs stand on the foundations of physical science,” the Nobel committee stated on X (previously Twitter). “They have showed a completely new way for us to use computers to aid and to guide us to tackle many of the challenges our society face.”
Ellen Moons, a professor at Karlstad College in Sweden and chair of the Nobel committee on physics, described AI’s promise and peril in remarks at a press convention in Stockholm on Tuesday. “The laureates’ discoveries and inventions form the building blocks of machine learning that can aid humans in making faster and more reliable decisions—for instance, when diagnosing medical conditions. However, while machine learning has enormous benefits, its rapid development has also raised concerns about our future. Collectively, humans carry the responsibility for using this new technology in a safe and ethical way for the greatest benefits of humankind.”
