So much is taught. Yes I agree it is probably necessary for those who have never seen it. I was just revisting because I had taken this course somewhere else a graduate student more then 30 years ago. The teacher is excellent, but I was literally trying to keep myself alert. Must be my age. I had to warm up my tea cup to keep me going. Very Nice presentation.
When you started talking about vorticity and singularity I was reminded by somebody saying that in accretion disk of black holes very high velocities are seen. 0.1 the speed of light. You see you got me thinking again.
Thank you very much Professor Chakraborty, you are really clarifying minds with those subtle concepts that for beginners it seems to be they come from nowhere¡¡¡
do(v)/do(x) is the change in vertical velocity with respect to change is x direction so as you move in x direction then the change in vertical velocity per unit lenght is that expression. now point B' is at a distance of delta(x) so vertical velocity at delta(x) is [do(v)/do(x) . delta(x) ] and the height of B' is that expression multiplied by delta(t)

I love how slowly and clearly each and every concept and intuition is explained.. Thank you sir
with due respect sir your lecture is amazing the way you explain each and every derivation great respects for iits

At 7:31 when Sir is writing the Taylor's Series, at last why does he write:
+ hot] × Delta t
What is that : +hot???
higher order terms
My utmost respect for the explanation, but the accent is killing me xD
Arey sir bangali hai toh accent mein thoda bengali pan aa jata hai koi nahi manage kar le😅
7:36 👈can anyone explain how that came?
can anyone explain concept at 7:36
Taylor series expansion
do(v)/do(x) is the change in vertical velocity with respect to change is x direction so as you move in x direction then the change in vertical velocity per unit lenght is that expression. now point B' is at a distance of delta(x) so vertical velocity at delta(x) is [do(v)/do(x) . delta(x) ] and the height of B' is that expression multiplied by delta(t)
hope this helps
