that is what I wanted to prove and I have proved it:He can’t have done it. The bank was robbed at 6.30 and he was with me at the time. QED.This is an abbreviation of a Latin phrase, quod erat demonstrandum, meaning which was to be demonstrated. ...
So here's the mean, I took the mean of x, x doesn't exist. Así que aquí es la media, tomé la media de x, x no existe. QED This really is a far-reaching compromise. It significantly alters the meaning of this text. Se trata de un compromiso de amplio alcance, que modi...
Physicists are no strangers to Feynman diagrams, but the meaning of the diagrams is not always clear, even to those who have used them. That confusion has deep roots, as Kaiser clearly and convincingly explains. To Feynman himself, a diagram depicted an actual physical process in space–time,...
In view of the prominent role played by this method in theory, let us discuss its physical meaning in greater detail. The procedure of successive refinement of the contribution from interactions is actually used in classical electrodynamics as well. Let us explain this by using as an example ...
As prices for goods and services fall, we pay less for them, meaning that we now have 额外的消费能力extra spending power来购买 with which to buy 其他东西other things。这增加了. This 经济中的需求,从而推动了increases demand新生产的创造 in the economy, which drives the creation of new ...
Words the boys didn’t understand either, but what was the point when their meaning was clear enough: Nickel. Parole che i ragazzi non capivano, ma non serviva capirle quando il loro significato era chiaro: Nickel. Literature In the end he decided to tell the story as far as the ...
This is related to the coupling to the background vacuum fluctuations, and can be derived from first principles using Fermi's Golden Rule in the context of QED. (The original Einstein coefficients were phenomenologically derived). You say it can be derived from first principles, but I...
In the The Quark and the Jaguar and Quantum Mechanics in the Light of Quantum Cosmology [10] Gell-Mann describes himself as an adherent to the (post-)Everett interpretation, although his exact meaning is sometimes left ambiguous. Steven Hawking is well known as a many-worlds fan and says, ...
I told him that it is an inherent quantity "baked in" to particles, but i couldn't really give a satisfying answer on the physical meaning of spin. A summary of the replies in this thread should, at least, set your students on a path toward refining and answering your (and...
No questions arise as to the meaning of the square root operation here and in (14) because f(a)1/2 is positive for all real a. Since the integrand has even parity φ(a) is odd. The two branches in (16) then appear as in Figure 1, with scaling of a so that a+(0) = – a...
