Phonograph Materials

February 9, 2010

2

In trying to gather up the materials I’ll need to build my phonograph, I have come to the conclusion that I’m way more likely to end up with a working phonograph if I follow these instructions: http://www.christerhamp.se/phono/matteson.html.  That means I’ll be trying for a tinfoil (or something similar) cylinder, not a wax one. Things I’ll […]

An Excursion to the 19th Century

February 4, 2010

Starting this blog in the paleolithic era was almost an afterthought.  In retrospect, I’m glad because the questions I’m examining here are very important and will become a point of reference for the entire project.  Questions like, “What is technology,” and, “What are human beings in the first place?”  Nevertheless, it has gone kind of […]

Part three of the Throwing Spear Saga is still coming.  I promise.  But … on Sunday I watched part one of the Nova documentary “Becoming Human“.  Part one was entitled “First Steps” and it seems to tie very neatly into my own speculations from the Ancient Computing Revolution post. The main question that “First Steps” […]

Cartesian Divers

This post is for everyone who might want to play with Cartesian divers, but especially for the Fast Track kids from Arisia 2010.  For a hands-on science session this year, I showed some of the kids how to make Cartesian divers, but the materials we used made it difficult to do it with so many […]
