The second statement was established before Einstein's equation of E = mc^2, which was intended to prove that matter can be converted to energy, not about the creation or destruction of matter. Conservation of mass was thought to be true until it was merged with conservation of energy into the "conservation of mass/energy" concept.
FAQ: Thermodynamics, meaning of gamma 1. What is thermodynamics? Thermodynamics is the branch of science that deals with the relationships between heat, energy, and work. It also studies how these factors affect physical properties and behavior of matter. 2. What is the meaning of gamma in thermodynamics?
Consider an energy eigenstate. We know that measuring the energy of this state we will get the eigenvalue of it as our measurement value. But what is the meaning of the eigenvalues of the projector? Since the projector is Hermitian, its eigenvalue is observable, but how do we measure it?
Looking for a resolution of an apparent contradiction on the meaning of the word 'particle' This is something that's bugged me for a long time and since I don't have any particular expertise in the subject, maybe I'm missing something obvious.
One should first and foremost understand that superposition has both a mathematical and physical meaning, or rather it originates as a mathematical property of the system description which will have implications in physics. The mathematical concepts are fairly straightforward aspects of linear algebra which will be briefly reviewed first.
FAQ: "y as a function of x" meaning 1. What does "y as a function of x" mean? "Y as a function of x" is a mathematical expression that represents the relationship between two variables, y and x. It means that the value of y is dependent on the value of x and can be expressed as a function of x.
From Sleeth's second post, second paragraph, it actually sounds as if he is meaning "matter" instead of mass. The burning wood example, for instance. Last edited: Jan 22, 2005
thrust is the ability to move a 1 pound object at 32 feet per second per second. What does per second per second mean? Does that mean for every second, the object has moved 64 feet in a given direction? if air molecules are moved at 3200 feet per second per second to deliver 100 pounds of...
Matter definition:physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy. Material definition:the matter from which a thing is or can be made.
The broadest definition is the word's use adjectivally to mean "matter of plant origin" to distinguish it from "animal", meaning "matter of animal origin". More specifically, a vegetable may be defined as "any plant, part of which is used for food", [4] a secondary meaning then being "the edible part of such a plant". [4]
