1. Do you like math?
How about Vector and Calculus?
Considerable possibility to meet these guys in our life as a graduate students 

Objectives
Qualitative approach
Applications
Summary

4. Objectives We can identify qualitative meaning of divergence and curl
Hopefully, we can apply this concept to Maxwell’s equation

5. What is scalar and vector?
Scalar: Quantity
Vector: Quantity + Direction

6. Let’s see more qualitatively!!
What is divergence and curl?
Divergence
Curl
Let’s see more qualitatively!!

7. Divergence
Vector
Scalar

8. Curl
Vector

9. Let’s see again
Divergence
Variation or change !!
Curl

10. Applications

11. Applications
Hint:

12. Summary Qualitative identification of divergence and curl
Application to Vector Identity
Don’t be afraid of Vector Calculus 

13. Thank you 
