Natalie Wolchover for Quanta Magazineasked several physicists what a particle is. She came away with several points of view. For example, the particle as a “irreducible representation of a group”: It’s the standard deep answer of people in the know: Particles are “representations” of “sy...
comingfrom the “particle”-physics tradition, who hold that QFT is fundamentally a formalism for describing processesinvolving particles, such as scattering or decays. A typical example of this position is Weinberg [5], who cannotcertainly be suspected of ignoring general relativity.These dif f i...
However, this does not yet give us an idea how a particle can ever be a wave. When we imagine a particle, we see a little ball, located at a particular position at a specific time and propagating at a particular velocity. If particles are to be represented by waves, then we must be...
Theoretical developments related to the gravitational interaction have questioned the notion of particle in quantum field theory (QFT). For instance, uniquely-defined particle states do not exist in general, in QFT on a curved spacetime. More in general,
What is the purpose of a particle accelerator? What particles can be accelerated by a linear accelerator? What is a boson particle? What do scientists study using a particle accelerator? What are the two types of particle accelerators? What is a neutrino particle? How big is a particle accele...
What is the ratio of mass of a gold atom and an α-particle ? View Solution What is the approximate energy released by the complete annihilation of an alpha particle? View Solution The alpha particles are View Solution A radioactive nucleus of mass number A, initially at rest, emits an ...
A semiconductor is a substance that can act as a conductor or insulator depending on other factors, enabling it to serve as a foundation for computers and other electronic devices. The term semiconductor is now widely associated with integrated circuits. ...
Particle physics is a branch of physics that studies the particles that make up matter. So this branch of physics tries to understand matter at its most fundamental level and how matter behaves at that level. It also tries to understand how matter interacts and turns from one form to another...
What is a way to unite civilization and create a new and better future for humanity? I will answer these questions now What is a personal unifying principle? A unifying principle organizes something that was previously unorganized. If your psyche is disorganized, a strong new interest can organiz...
elements are placed in the interior of the DEM elements, and forces and moments applied to them are transferred to DEM particles. You can bring your own particle shape, but the SPH elements must be smaller than the DEM particles in order for them to fit, which is a limitation of this ...
