“They used physics to find patterns in information: This year’s laureates used tools from physics to construct methods that helped lay the foundation for today’s powerful machine learning. John Hopfield created a structure that can store and reconstruct information. Geoffrey Hinton invented a method that can independently discover properties in data and which has become important for the large artificial neural networks now in use.“

“They cracked the code for proteins’ amazing structures: The Nobel Prize in Chemistry 2024 is about proteins, life’s ingenious chemical tools. David Baker has succeeded with the almost impossible feat of building entirely new kinds of proteins. Demis Hassabis and John Jumper have developed an AI model to solve a 50-year-old problem: predicting proteins’ complex structures. These discoveries hold enormous potential.“

Nobel Academy

The 2024 Nobel Prize has cemented the relevance of Artificial Intelligence (AI) as one of the driving forces behind scientific innovation. Both the Nobel Prize in Physics and in Chemistry were awarded to scientists whose contributions have revolutionized the field of AI and its applications in areas as diverse as machine learning and protein decoding.

In Physics, Geoffrey Hinton, known as the “Godfather of AI,” and John Hopfield, a professor at Princeton, were honored for their groundbreaking research in neural networks and deep learning. The artificial neural networks developed by Hinton mimic the functioning of the human brain, enabling machines to learn from data—a process fundamental to advancing technologies such as virtual assistants and image recognition. Hopfield, in turn, created a neural network model that uses incomplete patterns to find associations, a concept that has influenced how AI systems can “remember” and process information efficiently.

These technologies are the foundation of modern AI systems, such as ChatGPT and facial recognition, which use deep learning to operate with increasing sophistication. While Hinton has celebrated the contributions AI can bring to humanity, he has also raised concerns about the dangers of a lack of regulation in the field. After leaving Google in 2023, Hinton began warning of the existential risks posed by superintelligent machines that could potentially get out of human control.

In Chemistry, the Nobel was awarded to Demis Hassabis and John Jumper from DeepMind, a Google subsidiary, in recognition of their work in decoding the structures of microscopic proteins using AI. This technology, developed through the AlphaFold system, can accurately predict protein shapes, something that was previously a complex and time-consuming challenge for scientists. Along with Hassabis and Jumper, biochemist David Baker was also recognized for his contributions to protein design, which enable advancements in biotechnology and the creation of new medical treatments.

The impact of these discoveries cannot be underestimated. Protein decoding has direct applications in drug development and therapies, ushering in a new era of innovation in medicine. AlphaFold, in particular, is already being used to accelerate research into various diseases, paving the way for more efficient and personalized treatments.

However, the laureates’ proximity to Google has sparked criticism and concerns about the dominance of big tech companies in scientific research. The company has been the subject of antitrust investigations in the United States, with regulators pushing for a possible breakup of the Google empire. These large tech corporations surpass traditional academia in many aspects, both in terms of funding and cutting-edge research output, raising a debate about the role of academia in the future of innovation.

Dame Wendy Hall, a computer scientist and AI advisor to the United Nations, pointed out that the Nobel committee had to be “creative” in awarding Hinton and Hopfield in the Physics category, as there is no specific Nobel for computer science. The critique reflects a broader issue about how AI advancements should be recognized within the context of traditional Nobel categories.

These prizes reflect the rapid changes AI is bringing to various fields of knowledge. While AI undeniably offers promises for the future, there is growing concern about how this technology should be regulated and used ethically. With large tech companies like Google leading the race, the competition between the private sector and traditional academia intensifies, and control over the direction of scientific research may increasingly tilt in favor of corporations.

Ultimately, the 2024 Nobel Prizes not only highlighted extraordinary contributions in AI but also raised questions about the balance of power between academic research and the corporate sector, as well as concerns about humanity’s future in the face of a technology as powerful as AI.

    Quem não sabe, ensina? A docência, a academia e o verdadeiro significado de saber

    ByMaurício V. Brant Pinheiro

    Este ensaio parte de uma experiência pessoal na formação em Física na UFMG para refletir sobre o significado da docência e a persistência do clichê “quem não sabe, ensina”. A partir da tradição filosófica de Aristóteles — para quem ensinar é expressão do verdadeiro conhecimento — e da ironia de George Bernard Shaw, o texto investiga as tensões contemporâneas do ensino superior.

    Argumenta-se que a frase sobrevive não por sua veracidade, mas por refletir problemas reais: desvalorização da docência, excesso de burocracia, foco em métricas acadêmicas, perda de prestígio social e dificuldades estruturais da universidade. Ao mesmo tempo, discute-se a crescente superespecialização e a redução do repertório cultural, tanto entre docentes quanto discentes, bem como o surgimento de formas superficiais de difusão do conhecimento fora da academia.

    O ensaio sustenta que ensinar é uma atividade intelectualmente superior à mera execução, pois exige compreensão profunda e capacidade de explicitação. Em um contexto marcado pela inteligência artificial e pela abundância de informação, a docência se revela não como atividade secundária, mas como função central na organização do conhecimento. O texto conclui que o problema não está em ensinar, mas em não distinguir entre aqueles que apenas ocupam a posição de professor e aqueles que efetivamente formam pensamento.
