It seems like physics, AI, mathematics, history, & economics etc are seen as sexy things to talk about on podcasts etc but not chemistry. I wonder why?
FDA is now open to Bayesian statistical approaches. A leap forward!
Bayesian statistics can help:
✅ Clinical trial design
✅ Finding the optimal dose
✅ Extrapolation to children
✅ Leveraging phase 2 results in phase 3
The observer effect in quantum physics is the phenomenon where the act of measurement or observation alters the state of a quantum system, causing it to behave differently than it would if unobserved. This interaction often collapses a particle's wave-like potentiality into a definite, measurable state, challenging classical notions of objective reality.
The Naroditsky family shares the sad news of Daniel’s unexpected passing. Daniel was a talented chess player, educator, and beloved member of the chess community. We ask for privacy as the family grieves.
Short explanation of the physics Nobel Prize 2025
In classical mechanics you can know where a particle is and its momentum at the same time. In Quantum mechanics you can't. All information is in the wavefunction. Even if a particle is trapped, part of the wavefunction..

Have you heard of Cooper pairs?
In an ordinary conductive material, current flows because there are electrons that are free to move through the entire material. In some materials, the individual electrons that push their way through the conductor may become organised, forming a synchronised dance that flows without any resistance. The material has become a superconductor and the electrons are joined together as pairs. These are called Cooper pairs.
Cooper pairs behave completely differently to ordinary electrons. Electrons have a great deal of integrity and like to stay at a distance from each other – two electrons cannot be in the same place if they have the same properties. We can see this in an atom, for example, where the electrons divide themselves into different energy levels, called shells. However, when the electrons in a superconductor join up as pairs, they lose a bit of their individuality; while two separate electrons are always distinct, two Cooper pairs can be exactly the same. This means the Cooper pairs in a superconductor can be described as a single unit, one quantum mechanical system. In the language of quantum mechanics, they are then described as a single wave function. This wave function describes the probability of observing the system in a given state and with given properties.
The properties of this wave function play a leading role in the 2025 physics laureates’ experiments.
