Laying down a layer of aluminum foil, then paper, then foil... you make a stacked film capacitor that you can listen to as it regulates a simple oscillator circuit. Hard not to learn from this activity. Podcast

Starting with the story of the unstable but inquisitive cavalry man we find out what the four traces are on your sleep chart recording. Podcast

I was expecting a just the music concert. Join me on my drive down from the Blue Mountains to the Penrith concert hall where harvested more than I expected: Full Wikipedia lectures on the 1812 with cannons recorded from 1958, youth playing a piece about Auschwitz, and Piano "Homage to Liszt" Podcast

Introduction Podcast: What do they look like? What do they do? Podcast

Using two rolls of Al foil and two of lunch wrap we build a useful capacitor and understand how they are made. Podcast

Here we suspend two Pendulum on a string (Coupled pendula) , pull one back, release and it will slowly stop while as if by magic it's partner will begin to move. Podcast

Having let slip there are "Compound" pendula which are useless for keeping time, I confess to the categories of pendula: Simple, Coupled and Compound. It is beautiful but pretty deep in that we are so close to CHAOS and somehow life itself through pendula. Who would have thought. Podcast

Here I FAIL by calling coupled pendula "Compound" which is incorrect.  A less sexy set up allows you to follow mathematics of two separate "modes" and understand the seemingly less complex two pendula on a string. Podcast

Listen and learn about transistors ..... the name of the terminals, how to wire them up and what they do. Podcast

Attach a card to a pendulum and use a computer mouse to track the movement on a computer. This is a key science activity in education. Labview can really demonstrate acceleration and velocity. Podcast
