Cooking the food in front of you

By -
An idea I picked up from sitting in on Nassim Nicholas Taleb's classes is that of "cooking the food in front of you, instead of showing you the prepared dish." He uses this phrase when he is going to do some Mathematica programming right there, live, in front of the class.

This type of teaching inspired me to write a Python harness for comparing different hash functions in front of my class. I don't think any of them had ever seen an instructor do this before. And I am pretty sure they gained from seeing it.

It's not as anxiety-free (for the lecturer) as "showing them the prepared dish," but I think the students learn more from this form of presentation.

Libertarians, My Libertarians!

Cruel to be kind means that I love you . Because, while I think you are mistaken, your hearts are in the right place -- yes, even you, Silas --  unlike some people .

"Pre-Galilean" Foolishness

 I am currently reading The Master and His Emissary , which appears to be an excellent book. ("Appears" because I don't know the neuroscience literature well enough to say for sure, yet.) But then on page 186 I find: "Asking cognition, however, to give a perspective on the relationship between cognition and affect is like asking astronomer in the pre-Galilean geocentric world, whether, in his opinion, the sun moves round the earth of the earth around the sun. To ask a question alone would be enough to label one as mad." OK, this is garbage. First of all, it should be pre-Copernican, not pre-Galilean. But much worse is that people have seriously been considering heliocentrism for many centuries before Copernicus. Aristarchus had proposed a heliocentric model in the 4th-century BC. It had generally been considered wrong, but not "mad." (And wrong for scientific reasons: Why, for instance, did we not observe stellar parallax?) And when Copernicus propose...
