How seamlessly Grant adapts and emulates the step-for-step Sal explanation style when it comes to really explaining the math and algebra down to the most operative level (something Grant usually doesn’t do on his own 3blue1brown channel) just once again goes to show what a ridiculous multi layer genius this man is. I salute you, Sir! You’re a mastermind and a gift to math students all over the world.

I was hoping for a 3B1B video on this topic cuz I don't know anything about it and he explains things really well; needless to say it's a massive surprise to hear him on here! :D

*_Why that 'nudge' feels familiar?_*

As always, you've taken a subject which haunts some (me, 15 minutes ago), and made it feel intuitive.

7 years later and another electrical engineering uni undergraduate has been saved. +1 for simplicity. Really appreciate it.

Khan Academy strikes again, another great video. I wanted to refresh my understanding as to why a particular equation in my work is partial.

You have incredible teaching skill, when I watch 3blue1brown I can visualize everything, and see the purposes behind every math equation

I'm taking Andrew Ng's machine learning course on Coursera, and when Andrew showed the equation for gradient descent, I was able to decipher what it meant thanks to Grant's intuitive approach of little nudges and visualization. Thank you Grant!!! You are a phenomenal teacher!

How much do u want sal to know lol. Sal is not a god that knows everything, he can't make thousands of videos for free for you, at any level lol. He must find others who help. This guy is amazing, his technique helped a lot. In fact a new person helps you understand ways in a new idea so it makes a spark. Hence a lot of people like tutors..

I used to think calculus was hard, now It's super easy, it's advanced geometry and stats that's really hard for me now. but next year I'm taking intro to math stats and some actuarial stats classes so hopefully I'll be able to get that under my belt.

Am I the one that thought that that parabola was the most beautifully drawn they have ever seen?
