To do something a bit different during this Covid-19 lockdown I decided to set up my very own YouTube channel to which you may (or may not) wish to subscribe.

I’m new to this so I posted a short video to test how it works. It’s a little video explainer about Cramer’s Rule in linear algebra I made using Screencast-o-matic. I’ve done a lot of these over the past few weeks but they’re not what the channel is about: I posted this example is just to try out the system (mainly to see how long the upload would take).

I put this up yesterday and I’ve already amassed five subscribers so I’m well on the way to becoming a YouTube sensation. I may even become viral so please ensure that you practice social distancing while watching the videos.

## Lecture Demonstration

I am very proud to be at the forefront of teaching innovation, frequently deploying sophisticated new technology in the classroom for the benefit of the student learning experience.

I thought I’d share one of the latest devices I have developed for the Linear Algebra part of my module on Engineering Mathematics as I am all too aware that not all lecturers have such a firm grasp of the range pf possibilities offered by novel educational appliances.

This sophisticated yet lightweight tool utilizes a pressure-sensitive adhesive (`blu tack’) to attach shapes cut from a flexible sheet of a substance derived from cellulose pulp (`paper’) to a rigid plastic geometric measuring device (`ruler’) in order to represent the magnitude and direction of a vector. Illustrated here is the version designed for use with a chalkboard; an alternative version in black is available for use with a whiteboard. The head can be detached in order to separate the concept of magnitude from that of direction.

Made from lightweight materials this device is easily carried to and from the lecture theatre and can be deployed in all weather conditions (apart from rain, wind, snow, etc).

This simple yet effective hi-tech teaching tool is available for purchase throughout the European Union for just €19.99 and in the United Kingdom for £599.50.
