Fluid Dynamics and Waves: Motion in a continuum - Oxford Mathematics 2nd Year Student Lecture
Вставка
- Опубліковано 1 кві 2024
- In this lecture from the second year 'Fluid Dynamics and Waves' course, Dominic Vella discusses what a fluid is, how it differs from a solid, and how to describe the kinematics of its motion. He focuses on two different reference frames (the laboratory frame and a frame that moves with the fluid) and discusses how to relate rates of change of quantities between these two reference frames.

All first and second year lectures are followed by tutorials where students meet their tutor in pairs to go through the lecture and associated problem sheet and to talk and think more about the maths. Third and fourth year lectures are followed by classes.
It is interesting to know these phenomenon and use these concepts in real life situations which seem to be easy but involves some great physical phenomenon
Realistically, that would require an understanding of your experience of pressure on a day-to-day experience…..
Understanding when you might require an entire stress vector to describe this facet of reality
Trust me my professor , you are great 🙏
Can I study this to clear jee advance
Really good vedio and knowledge

Dear lecturer,
I appreciate the smoothness that went into deriving this convective derivative - something thats not so easy in a topologically general setting…. Thats very powerful of you.
Youre familiar with the result that differences in adjacent streamlines will exactly equal the hydraulic flux between them - this would be the opportunity to emphasize,
IN LECTURES - what kinds of nonphysicality this continuum model will exhibit when considered on a scale of quantum particles - where the infintesimal fluid particles are of an ontologically suspicious nature.
This problem was not understood as relevant when Irene Moroz was lecturing this course.
I know this is not a course on quantum mechanics, but you are TRULY, impressing a continuum worldview onto the audience….
And pure realistically, this is not a correct worldview on a scale that is sufficiently small, in a very exact, practical, way….
So maybe, consider exploring this convective derivative a little more rigorously… other points, such as the apparently made up Helmholtz theorem.. are less important than expressing the full totality of this thing. - the nonlinearity of continuum fluid mechanics.
Im suggesting - an exploration of its nonreality in the small scale of non-continuum mechanics..
You can appreciate then - that the waves you will end up teaching have NOTHING TO DO WITH QUANTUM MECHANICAL REALITY if you cant face up to this flaw in the continuum model at this scale
I am from india how i admission to Oxford please tell me 🔜
By taking their entrance exam
