Find time of death of patient with differential equations
Mr. N.P. Sahani asked:
“The differential equation and solution for finding the time of death of a patient”
Answer:
See that the question is to find the time of death (Not predicting the time of death. I thought that when I read it first.)
I can give some links which will be helpful in this connection

Tensor
streess is tensor,then,what is meant by tensor?
rupasri
Ans:
Tensors are used to represent the relation between vectors. They are geometrical objects which show’s the relation between vectors, vectors and scalars.It is a geometrical maping of the relations .Tensor analysis ,a branch in mathematics is helping to solve the complex equations in which many vectors are involved

The SI & CGS unit of time is same .Why?
Almost in all systems of unit second is the unit of time, most probably because, second is the most convenient one, if we look at the guidelines for selecting a unit.
