Nuts (used with bolts) are the idea weight to drop from height to determine gravitational acceleration. Tied to string it then allows measurement to be efficiently made as you time the drop to tug duration and the retrieve the weight.  Having strings link together in 1 metre lengths then make variation of this factor a breeze. Then have one nut fall tug the next nut can allow a cascade of nuts to fall leading to an accurate experiment. Podcast

Listen to someone who is probably too interested in LEDs and diodes. Losev the discover of LEDs dies of starvation in a besieged city. Podcast

An extended object will have different parts going in different orbits leading to the tidal distortion. Podcast

By using the "Hill's glow and blow resistors" you can set up a series circuit that when one resistor is cooled the other one heats up. Podcast

A demonstration using heater wire to support a rotating spindle with needle is described.  Also the construction of a realistic inter-nuclear vibration potential aides in understanding why things get bigger with heat. Podcast

The general strategy of weaving several lines of inquiry to arrive at a nuanced understand is proposed.  This is not what Stalin practiced when he created a terror state in which if Lysenko felt you were not supporting Lamarck your career would be cut short.

The aim of these podcasts is to sharpen my cognitive/presentation skills.  I slip up here by saying V, potential difference had units Coulomb per Joule, I had obviously got it the wrong way around! Some clear background is given needed before you launch into this topic. Podcast

In the real world it is often necessary to move between quality and quantity in stages particularly when quantity is necessary to first get a presence and start up the systems that finally lead to quality. In podcasting I am tending to various quality issues while getting the flow of material.  The Roman insight to fighting the Carthaginian Navy, the US building 3 Liberty cargo boats a day as some of the many examples of a need to look after quantity first.
