Peter Hill Explains

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

Exploring all the different tracks of knowledge coming from focusing on the lesser known chicken facts. 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

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

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

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 various shades of terror lurking in almost every society is noted. 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

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

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

A small coil of nichrome wire is an ideal first electronic component for students to explore. Podcast
