I think it’s fair to say that without FQxI, our growing community which we now call “Mathematical Consciousness Science” would not even exist. The best funding agency ever! Really!
You’ve supported basically all workshops and conferences which were essential in my research. I think it’s fair to say that without FQxI, our growing community which we now call “Mathematical Consciousness Science” would not even exist. And the large grant you awarded us recently gives us the chance to make a real difference. Thanks so much! The best funding agency ever! (Really!)

For philosophy, which aims to give the big picture about humans and their place in nature, fundamental science is a gold-mine. FQxI has played a unique, and indispensable role, in breaking down the traditional disciplinary boundaries between science and philosophy. Long may it continue to do so!
Over the past 16 years, FQxI has been very successful in bringing together science, especially physics, and philosophy. That endeavour is invaluable. For fundamental science, in particular physics, has yielded extraordinary insights in to nature, and has shown human ingenuity, both conceptual and experimental, at its best. So for philosophy, which aims to give the big picture about humans and their place in nature, fundamental science is a gold-mine. And FQxI has played a unique, and indispensable role, in breaking down the traditional disciplinary boundaries between science and philosophy. Long may it continue to do so!

FQxI has catalyzed much-needed dialogue between disciplines that rarely engage in an intellectual discourse; such connections have already enabled path-breaking research and could drive future paradigm shifts…FQxI remains almost unique in this space.

FQxI has had an impact on science that vastly exceeds its size and resources.
From my perspective, FQxI has had an impact on science that vastly exceeds its size and resources. Its funding model distinguishes itself from more traditional sources, by selecting high quality proposals that emphasize originality and creativity. Their approach is far more likely to lead to real advances than, say, the U.S.’s NSF and NIH, where it is widely acknowledged that new and innovative submissions get squelched, all too often. Their grant calls are well chosen to be in broad areas which are of fundamental importance, and not part of some fleeting trend. They get applications from a wide range of researchers in science, philosophy, and history. Lastly, its highly original meetings have had an enormous influence on my thinking, and many other researchers, in ways that are very significant.

It’s hard to express the difference FQxI’s made–that you nurture and value work on expansive, risky topics. I think it gives courage to a lot of people.

FQxI is an important part of the fundamental physics community, especially regarding expanding the boundaries of what questions can be addressed.

PressRelease: Precision experiment puts pressure on quantum collapse theories
Quantum mechanics, the theory governing the microscopic world, is famously counterintuitive. A particle can exist in a superposition of multiple states, such as different positions, until a measurement is performed. At that point, the wavefunction describing that particle appears to ‘collapse’ to a single outcome. This puzzle lies at the heart of the measurement problem, famously illustrated by Schrödinger’s cat, suspended between life and death until observed. The XENONnT detector, which was designed to be sensitive to rare physics events, has tightened constraints on one family of possible solutions to the measurement problem, known as ‘collapse theories.’ The work, which was partially funded by FQxI, was reported in Physical Review Letters in March 2026.
