🧊🌌 Neutrinos Instead of Photons: Francis Halzen, IceCube, and the New Astronomy of the Invisible Universe
In our previous voyages across the Dirac Sea, we have mostly followed great theorists and mathematicians. Dirac, Pauli, Fermi, and others who drew conclusions about particles no one had yet seen from equations, symmetries, and the internal logic of nature. The neutrino may be one of the finest examples of such physics: a particle first…

🧠 When the Inner World Takes the Stage: Creativity, Dreams, and Hallucinations
In the first two parts of our triptych, we began with the external world. First, we saw that the brain is not a simple decoder of sensory signals, but a system that continuously makes predictions, compares them with what it receives from the senses, and corrects its own model of reality when a prediction error…

🧠 What Are We Conscious Of? Mental Focus, Neural Gain, and the “Spotlight” Mechanism
In the first part of our triptych, we saw that the brain is not a passive decoder of the external world. It continuously maintains an internal model of reality, predicts what it should register, and corrects its own representation when a prediction error appears. But this opened a new question. If an enormous number of…

🧠 The Brain Is Not a Decoder: How Predictive Processing Builds Our Picture of the World
When we talk about the senses, we intuitively imagine a fairly simple process. The world emits or reflects certain physical signals, receptors register them, the nervous system transmits them, and the brain then “decodes” them and assembles a picture of reality. In that model, the brain is a kind of extremely powerful processor that receives…

🧠 Kirin 9050: A Forced Microelectronic Leap into the Third Dimension
When we talk about progress in microelectronics, for decades we have become accustomed to an almost automatic logic: a new processor means a smaller manufacturing process, more transistors on the same surface area, greater computing power, and lower energy consumption. We once spoke in micrometers, then in hundreds of nanometers, followed by 90, 45, 28,…

🐦 Archaeopteryx Flies Again: Soft Tissues, Lasers, and the Lost Biomechanics of the First Birds
Some fossils transcend the significance of a single species and become symbols of entire scientific ideas. Archaeopteryx is one of them. Ever since the first specimens were discovered in the German limestone formations of Solnhofen in the nineteenth century, this unusual animal — with feathers and wings, but at the same time also with teeth,…
