Calculus got me out of a speeding ticket. In court, the cop said I was “driving at a high rate of speed.” I told the judge I was driving at a constant speed using cruise control, hence my rate of speed was 0. He asked to elaborate, so I went on Calculus mode. The judge just gave me a smile and canceled the ticket, he said he’s never heard that one before.

Very old guy here - despite having an engineering degree - never (being honest!) got to grips with calculus such I felt any degree of decent understanding - this really has helped a lot. Never to late to learn. Appreciate this video and look fwd to next - maybe I'll die happy :) :)

There is none like  Professor Gibson, when it comes to the variety of topics that he covers. Absolute beauty.

@HeavenlyPress

I love when you can tell that someone really enjoys what they’re instructing

Your dedication shines in every lesson. Whether answering questions in the comments or re-recording videos to perfect explanations, you go the extra mile. You’ve built a community where no one feels alone in their struggles.  

You teach us to think, not just memorize. Your passion turns abstract concepts into tools we can use beyond the screen.  

Though we’re scattered across time zones, your impact unites us. Thank you for making education accessible, engaging, and empowering. The world is brighter because you share your gifts so generously.  

Grateful Students Everywhere.

Great great teacher! Be sure to tell the students that it’s called a ‘derivative’ of a function simply because it’s ’derived’ from the function.

Thank You Very Much (from Thailand)

@leopardtiger1022

Sir you are good  in explaining rate of change clearly  to the students of calculus. I am 84 years living in india watch your videos with admiration.

@bucs2021

Mr. Gibson, the king of Math and Science teaching/tutoring . His passion for the matter, is unmatched. This, and his deep knowledge, makes him and his videos so unique, and yet so special.
Thank You, Sir!

@DB-zk6td

This guy and his website got me through engineering school. Anyone I hear of having issues with math classes on a college level I always send them to his website. His explanations are so clear.

@tonykimani9933

My favorite guy already overtaking Organic chemistry in his way of teaching 🎉

@Farjah-q5p

Where were you when I was struggling to understand the concepts of derivative and integral 57 years ago. Looks so easy now the way you teach it; later in life I had to teach myself calculus in order to build and explain physiological models.

@VocabSpotlight

Your teaching style is fantastic—I love how you break things down step by step and connect the concepts. Thank you so much.

@amirlaplap

I always add your videos to my education playlist when they are added. As a PhD student in electronics, most of these concepts are familiar to me to some extent but the method of teaching and explaining you implement stems from deep thoughts and provocative ideas. They are not just copying the content of textbooks on the whiteboard. You have critically studied them and thought deeply about them from as many aspects as possible and after truly assimilating them you share them with us with your own intuitive method. Kind regards, Amir.

Next semester i go to college but I'm in my late 20s this man is very good at explaining everything I'm not good at math but i take engineering what a suicide but i understand what math is in his videos he is good at explaining to beginners you can get it even how hard it is the way he explained everything more videos to come sir ❤ I am always watching.

@araujoao

One of the best explanations about derivatives on youtube. I should have landed here first. I m reviewing Calculus and wanted a simplified version for those concepts. Thank you so much

@shujazaidi2644

You are doing a great service Professor. Your passion for transfer of knowledge to others just pours through in every lecture. Thank you and keep it up!

@Badddi

The fact that is one hour video was great, love these complete explanations. Your rhythm is great and the time goes by easily.

@UffeHellum

I cannot begin to express my admiration, when you repeatedly say “this is easy, because”, about concepts that millions of us get stuck on. 
It is “easy”, in that it is undeniable, but not “easy” in that people tend to get it right the first fifty times.
Keep up your amazing work!

@siddharthpatil4917

Yesssss i can start understanding calculus now (plz continue this series) 👌👌
