- How Einstein's SR becomes GR?
ds2=dr2−c2dt2,
ds2=gμνdxμdxν.
When the s is constant ds2=0, isn't it true?
How to connect Einstein's SR with GR?
What is the GR-differential ds2?
What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
