I always watch your lecture from the 0:01s to the end. Then, I often listen without looking at the screen the second times on another day. Automatically, the information opens brightly. Exellent lecture with brilliant explanation. Although it is long , it worths the time listening to you Dr. D. It save me the time to read through the textbook tremendously since you are exellently explaining the content. Please continue your youtube lectures. I am always looking forward to them with much gratitude.

I’m taking this class in 2 weeks and i’m trying to prepare myself , these videos are so helpful! But i’m struggling with understanding 0.2 mm can also be 200 micrometer or how you convert is from 0.2 to 200 im not sure I’m making sense
