How to pronounce “heat conductivity” in English

Here's one of our nerdier parts of the book. This is our chapter on heat and energy. So, we have partial differential equations in the cookbook. The cookbook has the strangedistinction that I wrote thousands of lines of code to write the cookbook, 'cause we used lots of computer simulations to understand things like heat conductivity, like the diffusionof a brine. If you brine a meat, that's also run by a diffusion equation. So, tons of code were written to write this book and here's some of the equations. Here's another example of
