With just an iPad, students in any classroom across the world could soon reimagine the ordinary diagrams in any physics textbook—transforming these static images into 3D simulations that run, leap or spin across the page.

Metaphysics and the Matter with Things: Thinking with Iain McGilchrist was a collaborative conference put on by the Center for Process Studies (CPS) and the California Institute of Integral Studies (CIIS) in March of 2024. This three-day conference brought leading process thinkers across various disciplines, including physics, neuroscience, psychology, philosophy, and theology into critical dialogue with McGilchrist’s work in a collegial effort to assess, question, extend, and apply it.

Last month, Oxford PV’s breakthrough solar cell broke the efficiency world record and is the world’s first commercially available Perovskite solar panel.
How does it work? And what does this mean for the future of solar?
Thanks you so much to the team for allowing me behind the scenes into their development facility and for the free Halloween costume.

John Hopfield, one of this year’s winners of the Nobel Prize in Physics, is a true polymath.
John Hopfield has had a varied career and delights in working in the cracks between disciplines.
Sabine Hossenfelder is a very popular science communicator who focuses largely on topics in physics. Although much of her content is effective and without issue, there is an undercurrent of anti-establishment rhetoric that has grown immensely as of late, and it is an enormous problem. Sabine is a not a charlatan like most of my other targets, and this is not a hit piece, but rather commentary on this aspect of her work and how it came to be. If you are a fan of hers, consider this perspective.

1992, 31 October

On this day in 1992, the Vatican admitted that Galileo was correct in believing that the earth went around the sun.
2. In the first place, I wish to congratulate the Pontifical Academy of Sciences for having chosen to deal, in its plenary session, with a problem of great importance and great relevance today: the problem of ‘the emergence of complexity in mathematics, physics, chemistry and biology’
The emergence of the subject of complexity probably marks in the history of the natural sciences a stage as important as the stage which bears relation to the name of Galileo, when a univocal model of order seemed to be obvious. Complexity indicates precisely that, in order to account for the rich variety of reality, we must have recourse to a number of different models.
This realisation poses a question which concerns scientists, philosophers and theologians: how are we to reconcile the explanation of the world – beginning with the level of elementary entities and phenomena – with the recognition of the fact that ‘the whole is more than the sum of its parts’?
In this episode of Cosmology 101, we learn how the detection of the Cosmic Microwave Background (CMB) validated the Big Bang Theory and led to the development of the concept of cosmic inflation.
Explore the challenges and ongoing debates in cosmology as scientists seek to uncover the true nature of the early universe and the origins of cosmic structure.
Join Katie Mack, Perimeter Institute’s Hawking Chair in Cosmology and Science Communication, on an incredible journey through the cosmos in our new series, Cosmology 101.

Physicists in Germany have used visible light to measure intramolecular distances smaller than 10 nm thanks to an advanced version of an optical fluorescence microscopy technique called MINFLUX. The technique, which has a precision of just 1 angstrom (0.1 nm), could be used to study biological processes such as interactions between proteins and other biomolecules inside cells.
In conventional microscopy, when two features of an object are separated by less than half the wavelength of the light used to image them, they will appear blurry and indistinguishable due to diffraction. Super-resolution microscopy techniques can, however, overcome this so-called Rayleigh limit by exciting individual fluorescent groups (fluorophores) on molecules while leaving neighbouring fluorophores alone, meaning they remain dark.
One such technique, known as nanoscopy with minimal photon fluxes, or MINFLUX, was invented by the physicist Stefan Hell. First reported in 2016 by Hell’s team at the Max Planck Institute (MPI) for Multidisciplinary Sciences in Göttingen, MINFLUX first “switches on” individual molecules, then determines their position by scanning a beam of light with a doughnut-shaped intensity profile across them.
Joscha Bach is a German artificial intelligence researcher and cognitive scientist who works on on cognitive architectures, mental representation, emotion, social modeling, and multi-agent systems. We got connected over the hard problem of consciousness — namely, why do people seem to think it’s so hard? During our conversation we deal with the foundational questions of the technological future being built in Silicon Valley, the fever dream of machine intelligence, and try to understand why people seem to think that there’s even such a thing as the hard problem of consciousness in the first place.

A team of engineers and physicists affiliated with a host of institutions across Japan, working at the Japan Proton Accelerator Research Complex, has demonstrated acceleration of positive muons from thermal energy to 100 keV—the first time muons have been accelerated in a stable way. The group has published a paper describing their work on the arXiv preprint server.
