Herman Trivilino's latest activity
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.You asked for "idea of proof", and that's the idea: To show that the direction of the velocity is uniformly distributed. @jbriggs444... -
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.It's the first sentence in the passage you quoted: "The main assumption here is that the direction of the velocity is distributed...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.Which book? Are you still reading that advanced book? Your explanation isn't correct. What they're saying is that the square of the...

Herman Trivilino replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….Maybe, but it never made that clear, in my opinion. When I spoke of his writings what I should have included is the written accounts of...

Herman Trivilino replied to the thread I Physicists disagree wildly on what quantum mechanics says about real….I think that's a fair assumption. Bohr was famous for coraling new physicists at his institute into joining him in his office to help...

Herman Trivilino reacted to robphy's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with
Like.
Indeed… Draw a spacetime diagram. -
Herman Trivilino replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.That's an explanation often seen, but it can be misleading. To begin to understand this you must realize that to reach that conclusion...
-
Herman Trivilino replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.A definitive answer was given in the first reply. Adding an explanation is what makes it a discussion. Is it necessary for you to...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.Ahhh... At that point in my education I wouldn't have been able to understand that book, either. I suggest you start with a...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.You're welcome. I don't know what SE means. The part of the book you were reading appears to be a derivation of the Boltzmann...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.It means that you take the average. That's what the bracket notation <...> means. So the average value of ##v_x^2## is ##<v_x^2>##. And...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.The book you're reading is written for physics majors. Probably at the graduate level, so it's meant for students who've had previous...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.Yes, with the qualifications stated below. Not if you have a tremendously large number of molecules, which you do. So the chances of...
-
Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.Because the x-direction is chosen randomly. It could have been the y-direction that was chosen instead, or indeed any direction.

Herman Trivilino replied to the thread I What does equiprobable mean in the context of thermal motion?.What I can glean from the translation is that you imagine drawing an arrow representing the velocity vector for each molecule, and then...
