Online Resources
It took me a very long time to become comfortable with using anything other than my textbook and notes when learning concepts in school. However, I’ve learned that I best understand something when I can visualize it and clearly write out all the steps. Because of this, YouTube has been an amazing resource, as well as other online sources where I can see how other people interpret and explain these concepts.
3blue1brown - Originally a YouTube channel created by Grant Sanderson, 3blue1brown is a great resource for learning any type of maths with intuitive visualizations. In addition, he will sometimes do one-off videos on cool concepts in mathematics and has know started having guest videos!
Paul’s Online Math Notes - Paul’s Online Math Notes helped me a lot in high school to learn calculus as well as differential equations. With clear explanations and also so practice problems with solutions, it’s a resource that I sometimes go back to if I want to brush up on foundations of mathematics.
Very Normal – This is an amazing YouTube channel (that also has a substack of the same name) by recent Ph.D graduate Christian. Really clear and well-animated videos of many different statistical concepts, this channel has helped me a lot!
Statistics for Ecologists - Written by John Fieberg at the University of Minnesota, this is an amazing textbook with a lot of practical exercises. I went through the whole book and it helped me gain a good foundation of statistical modeling.
Primer - Though they rarely make videos, Primer is a YouTube channel with great animations that explains some basic statistical concepts.
Numberphile - This is a great YouTube channel to see professors and mathematicians explain problems in real time. Rarely any animations, it’s a lot of pen to paper explaining and working through a problem.
Flammable Maths - Though 2025 is his last year on YouTube, this is a fun channel solving math problems from algebra to calculus.
