Macroscopic object wave function - Physics Forums
2020年1月15日 · The macroscopic object wave function is derived from the Schrödinger equation, which is a fundamental equation in quantum mechanics. The equation describes the evolution of the wave function over time and can be used to calculate the probability of finding a macroscopic object in a particular state.
Heisenberg Uncertainty Principle and macroscopic objects
2024年12月14日 · The de Broglie wavelength of a macroscopic solid body gives you the uncertainty of its center of mass. You can check that by transforming the system into center of mass and reduced coordinates. This is a linear canonical transformation of the spatial coordinats, and the Schrödinger equation of non-relativistic QM is invariant under those.
The difference between microscopic and macroscopic cross sections.
2010年10月31日 · The macroscopic cross-section (Σ) has units of cm-1 is derived from the microscopic section according to Σ = N σ, where N is the atomic density of a particular nuclide. The reaction rate for a give interaction = Σ Φ , where Φ is the neutron flux.
Wavefunction of Macroscopic Objects - Physics Forums
2010年11月17日 · 1) Macroscopic objects have their own wavefunction, right? Would this wavefunction include physical attributes that would contain possibilities for certain features that macroscopic objects have (say the macroscopic object is a bed – the wavefunction would have possibilities for all the different colours the bed can be such as blue, black ...
Calculation of neutron transport cross section - Physics Forums
2013年7月12日 · The transport cross sections for water and heavy water are 0.45cm and 2.6cm. These values can be calculated using the equation macroscopic cross section = 1/mean free path, or specifically for water, 1-cos(theta) = 0.324, and for heavy water, 1-cos(theta) = 0.116. However, these values may differ from those in the cited text.
Microscopic and macroscopic physics - Physics Forums
2020年8月13日 · Microscopic and macroscopic physics are interconnected and complement each other. Macroscopic properties and behaviors of matter are a result of the interactions and behaviors of microscopic particles. Understanding the microscopic world helps us explain and predict macroscopic phenomena.
Is General Relativity Exclusively a Macroscopic Theory? - Physics …
2004年11月23日 · Macroscopic observations involve using our senses to gather information about objects or phenomena that are visible to the naked eye. Microscopic observations, on the other hand, require the use of specialized equipment, such as microscopes, to gather information about objects or phenomena that are too small to be seen with the naked eye.
Resolving the Clock Paradox: The Hafele and Keating Experiment
2011年1月31日 · "During October, 1971, four cesium atomic beam clocks were flown on regularly scheduled commercial jet flights around the world twice, once eastward and once westward, to test Einstein's theory of relativity with macroscopic clocks. From the actual flight paths of each trip, the theory predicted...
Stiffness of a single interatomic spring - Physics Forums
2012年2月25日 · This results in a stiffness constant of approximately 2.83 N/m for a single interatomic bond in iron. This value is obtained by considering the wire as a very stiff macroscopic spring and using the relationships between the stiffness of the whole wire, the number of side-by-side chains, and the number of interatomic bonds in
What does it mean to model the distribution of galaxies as cosmic …
6 天之前 · This correlation of motion can result in an apparent, macroscopic angular momentum of the "cosmic dust." The torsion mentioned refers to a geometric property in general relativity related to the curvature of spacetime in the presence of spinning matter. In this cosmic dust framework, the torsion and angular momentum are seen as emergent ...
