I have been spending the last few days simply in awe of this video:
Vi has done something here that I’ve never seen anyone do before: She has made logarithms completely clear and fun and accessible to everyone — not just to people who are already into math.
Why should you care? Well, the pitch and volume of every sound you have ever heard, the color and intensity of everything you have ever seen, how things feel when you touch them, and just about every other sensation by which your brain receives the world — all of it is on a logarithmic scale.
Considering that your entire experience of reality is best measured by logarithms, really understanding them is quite a big deal.
And Vi has singlehandedly, through this one lovely video, done away with all the formulaic misinformation and useless crap that so many people “learned” in school. In their place she has given us a perfectly intuitive and elegant explanation that is as easy as 1 + 1 + 1.
