On the right, a cartoon self-similar image - a picture of a room with a small pic of that room on a wall. On the left, the log of that image: every circular path within the image is mapped onto a straight line. Squares in the original image look like scalloped lines.
I'm sorry but this has just blown my mind...

Charles Petzold (author of Code) is working on a new book. Logarithms are mathematical functions that are the inverse of exponential functions. Natural logarithms, base e, take us closer to the physical world.

I'm happy because I just stumbled across a simple way to calculate the logarithmic mean of two numbers:
x /<lower_number> = <upper_number> / x
So, solving for 500 and 4000, you get a logarithmic mean of 1414. Nice. #math #logarithmicmean #logarithms

Daily #apprecalculus students go to the board daily to explain their thinking and my classes are part of an iPad pilot so we also are doing our work digitally but still by hand which is why I love the iPad! #inversefunctions #logarithms #exponentials

Experimenting with images and logarithms.
Process each pixel of an image, either by channel or as a packed long: get its logarithm, round to a certain no. of decimals, and revert back.

The takeaway? EVERY formula has conditions that make it valid. Skip learning them and you will make mistakes. Do yourself a favor: Always check conditions when applying a formula.
