⚛️ Quantum physics – The double-slit experiment explained simply! 👍‍ The famous double-slit experiment is one of the most fascinating experiments in modern physics. It demonstrates something that completely contradicts our everyday understanding: particles can behave like waves. For example, if electrons are fired through a double slit – a classic experiment in optics – an interference pattern appears on the detector, which is something we normally only see with waves. This means that as long as we do not observe the path taken by the electron, it behaves as if it were in several places at once. Physicists refer to this as the particle not being localized. In order for this strange behavior to become visible at all, the experiment must take place under very specific conditions: for example, in a high vacuum so that the particles are not disturbed by air molecules. Only when the particles are sufficiently decoupled from their environment does this peculiar quantum physical nature become apparent. In our Zoomposium, we talk to experimental physicist Prof. Dr. Gerd Ganteför about precisely such phenomena and the big questions of modern physics: • What role does the observer play in quantum physics? • What does the double-slit experiment tell us about the nature of reality? • Are there perhaps aspects of reality that go beyond classical materialism? • And are we already reaching the limits of physics here? An exciting insight into the mysterious structure of our reality – explained in an understandable way and with a dash of scientific humor. 📎 Information: https://philosophies.de/index.php/2023/04/16/zoomposium-gerd-gantefoer/ 📺 Interview: https://youtu.be/V4pUEEtFCUo

⚛️ 🤔 Quantum Physics Explained Simply – Participatory Reality! 🌐🔭 Does reality only come into being through observation? What initially sounds like metaphysics is a serious concept within modern quantum physics: the idea of the participatory universe, coined by John Wheeler. This does not mean that human consciousness “creates” the world. Rather, quantum mechanics experimentally shows that systems change their behavior as soon as they are coupled with their environment – i.e., “observed.” An unobserved quantum system behaves differently than a measured one. Reality thus appears not as completely fixed, but as processual—as something that takes concrete shape in the interaction between system and environment. Similar to how humans change their behavior when they feel observed, even elementary particles react sensitively to measurement arrangements. The crucial point is that these statements are not speculative, but experimentally verifiable. In the Zoomposium with Gerd Ganteför, we discuss precisely these questions at the frontiers of physics: What does the participatory principle mean for our worldview? What role does information play in quantum physics? Do we need a new metaphysics of time? And how far-reaching are the consequences of entanglement and quantization of reality? A conversation about the “enigmatic fabric of our reality”—explained in an understandable way and yet philosophically challenging. 📎 Information: https://philosophies.de/index.php/2023/04/16/zoomposium-gerd-gantefoer/ 📺 Interview: https://youtu.be/V4pUEEtFCUo

✨🔬 Quantum phenomena – laws of nature and spooky behavior 👻 How do these mysterious “spooky” effects actually arise in decoupled systems of quantum physics? And why does the coupling sometimes break down? 🤔 In our Zoomposium with Prof. Dr. Gerd Ganteför, we delve into the limits of modern physics and the “mysterious fabric of our reality.” Gerd explains in an entertaining and understandable way how observation, quantum information, and even time reversal invariance challenge our understanding of reality. We discuss, among other things: • The participatory universe according to John Wheeler • Immaterialistic aspects of modern physics • Entanglement and the basic research of Anton Zeilinger • Potential applications of quantum principles – from information preservation to science fiction ideas such as beaming An exciting kaleidoscope of physics, metaphysics, and scientific humor – perfect for anyone who wants to explore the limits of our knowledge. 📎 Information: https://philosophies.de/index.php/2023/04/16/zoomposium-gerd-gantefoer/ 📺 Interview: https://youtu.be/V4pUEEtFCUo

⚛️💡Quantum bit – What it is and why it matters! A quantum bit – or qubit – is the smallest unit of quantum physical information. Unlike a classical bit, which is either 0 or 1, a qubit can be both at the same time: 0 and 1 – and all states in between. This is precisely what makes it so revolutionary and, at the same time, so difficult to imagine. In the Zoomposium, Gerd Ganteför talks to us about why this property is not just a technical gimmick, but fundamentally changes our understanding of information, reality, and physics. Quantum information challenges classical notions of matter, time, and causality – and opens up new perspectives on quantum computers, information conservation, and the limits of physics itself. What does it mean when information is more fundamental than matter? And what role does the observer play in a quantized reality? These questions are at the heart of our conversation about the enigmatic fabric of our reality. 📺 Interview: https://youtu.be/V4pUEEtFCUo 📎 Information: https://philosophies.de/index.php/2023/04/16/zoomposium-gerd-gantefoer/
