Ratings and Reviews
The best online course I have ever taken. Unlike most of other MOOC, the instruction of this course is very easy to follow.
I am a Mechanical Engineer and like most of them engineers, I had very weak concepts of basics of Mechanical Engineering. Then I came across this series of courses from Dr. Whiteman and believe me or not, I have learned more from him than my 4 years at an engineering university. He has this amazing quality of delivering the concepts in a very easy, understandable way. I really want to thank Dr. Whiteman for designing this amazing course and Coursera for providing us the platform to learn. They are really serving the humanity and mankind.
As for Dr. Whiteman. I would say Thank you, Sir!!!!
You have my respect for the lifetime.
Excellent lessons with a theorical lectures well explained and several practical exercises, widely recommended.
