Why were pentaquarks so difficult to discover? [37] Are they a tightly bound system of five elementary particles, or a more weakly bound pairing of a baryon and a meson? [38] Mu problem: A problem in supersymmetric theories, concerned with understanding the reasons for parameter values of the theory.
Hempel's dilemma is relevant to philosophy of mind because explanations of issues such as consciousness, representation, and intentionality are very hard to come by using current physics, although many people in philosophy (and other fields such as cognitive science, psychology, and neuroscience) hold to physicalism.
In theoretical physics, the problem of time is a conceptual conflict between quantum mechanics and general relativity.Quantum mechanics regards the flow of time as universal and absolute, whereas general relativity regards the flow of time as malleable and relative.
These two theories upon which all modern physics rests are general relativity and quantum mechanics. General relativity is a theoretical framework that only focuses on gravity for understanding the universe in regions of both large scale and high mass: planets, stars, galaxies, clusters of galaxies, etc.
This is one of the most difficult aspects of quantum systems to understand. It was the central topic in the famous Bohr–Einstein debates, in which the two scientists attempted to clarify these fundamental principles by way of thought experiments. In the decades after the formulation of quantum mechanics, the question of what constitutes a ...
In physics, specifically classical mechanics, the three-body problem is to take the initial positions and velocities (or momenta) of three point masses that orbit each other in space and calculate their subsequent trajectories using Newton's laws of motion and Newton's law of universal gravitation.
