1) &quot;Not over explain it&quot; -- that&#x27;s really good advice. You don&#x27;t want to take the &quot;aha&quot; moment away from someone.<p>2) Thanks for the link! Definitely looking forward to your blog post&#x2F;postmortem (don&#x27;t let BetterExplained die!). Have you found learning to be less enjoyable by writing about it, or do you end up discovering a dozen other tidbits of math magic you want to share with everyone?<p>Two more questions if you don&#x27;t mind :)<p>3) What are your thoughts on word problems?<p>For example, in most linear algebra textbooks, you are given matrix and are asked you to process it. Rarely are you given a word problem and are asked to think through the entire process (data and operations matrices setup --&gt; processing --&gt; meaningful end result).<p>4) For inspiration, what are you experiences explaining concepts in a cross-disciplinary manner?<p>When I was a student, I never understood <i>why</i> a concept is important. Homework problems were abstracted out of all real-world context to train for mechanical problem solving. Only now, after exploring data and writing algorithms in health, journalism and finance, have I finally been able to answer the question I always had as a kid: &quot;why is this stuff useful?&quot;
