Exhausted by environmentalism? Take up driving instead, says A-Level physics question.

May 23, 2013

Yesterday, a colleague from the geology department described an A-Level physics question he’d noticed while invigilating earlier that week. An avid cycler and environmentalist, he was somewhat aghast to discover a question that implied CO2 emissions could be reduced if cyclists did everyone a favour, and journeyed in cars like the rest of us. The […]

Making A TED-Ed Video – Part 2

The charity ‘Technology, Entertainment, & Design‘ – or ‘TED’ – has a recent offshoot project. It’s called TED-Ed, and aims at facilitating a collaboration between educators and animators to make online educational videos. I’ve been working with them over the past few weeks to make a video, and yesterday they sent me the materials to […]

The charity ‘Technology, Entertainment, & Design‘ – or ‘TED’ – has a recent offshoot project. It’s called TED-Ed, and aims at facilitating a collaboration between educators and animators to make online educational videos. One of my old students sent me an email suggesting I might be interested in applying. A week later, I had a […]

An Introduction to Theoretical Physics (Part 5 of 5)

Introduction to Part 5 At this point, let’s reflect upon the topics we have included in our little exploration.  I have tried to place the topics into two groups: Physics  Mathematics Resistor Addition (Series and Parallel) Combinations Ohm’s Law Factorials Kirchoff’s Laws of Electrical Circuits Pascal’s Triangle Electrical Potential Difference Summation Notation You’ll notice that a great […]

Introduction to Part 4 Now we have a solution for the tesseract, we could ask about still higher dimensions.  Rather than a case by case study, we might now aim at a general equation that tells you the resistance of a cube of identical resistors of any dimension.  We have a little experience with this when defining […]

Introduction to Part 3 Having solved the initial problem, calculating the resistance of a cube of identical resistors, what can be done to make the equation more general?  The first abstraction was to move from 2 dimensional circuit diagrams to trying to solve 3 dimensional circuit problems. Could we investigate higher dimensions?  What about a 4 dimensional […]

Introduction to Part 2 In Part 1, the importance of abstraction was justified as a way to satisfy the human goal of knowing and predicting the most, while remembering the least.  It enables physicsists to describe the workings of the universe with a small collection of simple patterns. Satisifed that the resistor addition equations can be mathematically […]
