  You are the reason many future engineers pass control systems and receive their degrees. Please keep up the good work!

  &quot;Each open-loop pole has its open-loop zero friend and they draw a path between the two. And if a pole or a zero doesn&apos;t have a friend then they go off to infinity searching for them.&quot;<br>- Brian Douglas<br><br>idk why but feelsss

  Some of the lecturers from my University does NOT deserve their salaries. Thank you.

  Hi Brian,<br>I &nbsp;found this very interesting to find. My dad, Walter R. Evans, invented Root Locus. &nbsp; As his daughter, I never understood root locus. &nbsp;My brother Greg is writing a biography of my dad and what he went through to get root locus method approved. &nbsp; &nbsp;Thank you for posting this video. &nbsp;I know my dad would &nbsp; Have really appreciated any way of getting his ideas across to students. &nbsp; Well done.

  One of my favorite controls books is &quot;Control Theory Second Edition&quot; by JR Leigh.  There are a lot of great books that describe the theory and show you the math, but this book explains most of the concepts in words. I think engineers can get a good understanding of &quot;why&quot; the theory as opposed to&quot;what&apos;s&quot; the theory from this book.

  This channel has genuinely made me want YouTube to implement a &quot;Buy this guy a beer&quot; button. Your videos are all so damn straightforward to understand, and you&apos;ve taught me more in two days than I&apos;ve managed to understand from 19 hours of lectures on the subject. Thank you so so much.

  &quot;Each open loop pole has their open loop friend and if they don&apos;t have a friend they go out to infinity searching for them&quot; those were probably the most beautiful words i have heard in my engineering education so far!

  Best thing my Control System teacher ever did: recommend this channel.

  It&apos;s a shame tutorial videos dont get as many likes as the views they get. Beautifully explained 👌

  I&apos;ve been trying to understand root locus sketching for hours and this video made me understand it better than one whole semester of lectures
