The Strings 2019 conference held July 9–13 in Brussels, Belgium, featured talks with Robbert Dijkgraaf, Director and Leon Levy Professor of the Institute; School of Natural Sciences Professors Juan Maldacena, Edward Witten, Nima Arkani-Hamed, and Nathan Seiberg; and IAS scholars past and present.
On May 29, 2019, the Institute for Advanced Study hosted a celebration of The Universe Speaks in Numbers by frequent Director's Visitor Graham Farmelo. The public event, which was held on the centenntial of the 1919 eclipse that provided the first experimental verification of Einstein's theory of relativity, brought together some of the world's foremost science communicators for an afternoon of talks discussing the close relationship between mathematics and physics.
"In a perverse way, the refutation of a great conjecture can be even better news than its success, since the failure makes clear that our imagined map of the mathematical world is seriously wrong. Defeat can be productive, the reverse of a Pyrrhic victory." In a column for Quanta Magazine, Robbert Dijkgraaf, Director and Leon Levy Professor, covers how conjectures are proven, what makes a particular one great, and the role conjecture plays in the advancement of mathematics.
On May 4, 2019, Demis Hassabis, Co-founder and CEO of DeepMind, discussed the capabilities and power of self-learning systems in a public lecture at the Institute for Advanced Study.
“From the perspective of gravity, [a black hole] is the simplest object we know of, no more than a hole in space. At the same time, according to quantum theory, it is the most complex object, the most compact way to store matter and information.” Robbert Dijkgraaf, Director and Leon Levy Professor, discusses the paradoxical nature of black holes and their role in twenty-first-century physics.
Writing for NRC Handelsblad, Robbert Dijkgraaf, IAS Director and Leon Levy Professor, likens IAS Professor and Abel Prize Laureate Robert Langlands’s program, “a deep connection between two completely different parts of mathematics: on the one hand, numbers and their relations, on the other hand, geometrical patterns and their symmetries,” to a mathematical Rosetta Stone.
“It is indeed an endless cycle of imagination and concentration, of divergence and convergence, of playing and thinking that determines the rhythm of science and scholarship,” writes Robbert Dijkgraaf on the occasion of becoming the Institute’s ninth Director and first Leon Levy Professor. “The Institute is devoted to creating and supporting these experiences.”
Why are there six “flavors” of quarks, three “generations” of neutrinos, and one Higgs particle? Robbert Dijkgraaf, Director and Leon Levy Professor, explores the complex search for a single description of reality.
Reductionism breaks the world into elementary building blocks. Emergence finds the simple laws that arise out of complexity. Robbert Dijkgraaf, Director and Leon Levy Professor, explores how these two complementary ways of viewing the universe come together in modern theories of quantum gravity.
Addressing an audience at Vrije Universiteit Brussel on the occasion of receiving an honorary doctorate, Robbert Dijkgraaf, Director and Leon Levy Professor, spoke on the state of science today: “Simply put, we are moving to the next level. The previous century can be characterized as the search for the building blocks of reality....This century will explore the brave new world that can be constructed with these building blocks, in our labs and in our minds.”
Scientists are working to decipher and harness the power of quantum mechanics, but the strange nature of entanglement and other quantum phenomena continues to confound researchers, posing new and mystifying questions. On January 9, 2019, PBS aired “Einstein’s Quantum Riddle,” now available online, featuring Institute Director and Leon Levy Professor Robbert Dijkgraaf, who provides audiences with a deeper understanding of nature’s quantum language.
The Usefulness of Useless Knowledge by Director Robbert Dijkgraaf and IAS founding Director Abraham Flexner “read in the right government places, might inoculate the nation against philistine utilitarianism,” observes Pulitzer Prize–winning columnist George F. Will in the Washington Post.
“Our whole education is a process of confrontation between our imagination and the reality of established facts,” Institute Director and Leon Levy Professor Robbert Dijkgraaf tells the European Molecular Biology Laboratory. “I think the greatest scientists have such an intense curiosity that they’re not discouraged by the current practice of the field and they push the boundaries of knowledge.”
In a video produced for Inverse, IAS Director and Leon Levy Professor Robbert Dijkgraaf sits down with a group of seven-year-olds to answer the question “Why is the sky blue?” Through a series of simple experiments, Dijkgraaf and the “class” explore light and color to arrive at an answer.
What drew Robbert Dijkgraaf, Director and Leon Levy Professor, to the world of mathematical physics? He explains that it was the fundamental fact that all the structure we see around us — all the natural beauty, order, and disorder — can be explained by mathematical equations. “I got this feeling that deep mathematical facts must also express something deep about nature,” Dijkgraaf tells the Simons Foundation.
“The basic element of science is not the knowledge per se, but the method, the romantic feeling that there’s this vast ocean of knowledge to be explored,” says Robbert Dijkgraaf, Director and Leon Levy Professor. Dijkgraaf reflects on his early encounters with science in his childhood attic in the Netherlands for an animated piece by Nautilus Magazine.
