An Intuitive Derivation of Eigenvectors
really good explanation.
I like it even better than 3blue1brown or visualisations that I had seen.<p>It is better because it really covers every step of the construction process.<p>And offers explanation of why certain thing are not the right construction blocks. The author gives a visual example, for example, of why basic vectors 1,0 -1,0   are bad.  The article shows they cannot span the whole space.<p>Those kinds of explanations of 'bad constructions' are difficult to show in visualizations, that show 'good' constructions only.<p>But, yet, in my view, these negative examples,  are really helpful to explain the material that otherwise, requires 'intuition'.<p>Not everybody  has same intuition, so showing negative examples/impossible constructions, and why those do not work -- is a good way tuning one's intuition.<p>---<p>On a separate note, I am wondering if such good step by step + counter examples, knowledge presentation -- is a result of author studying at MIT, or a natural trait (or both) ?
