Harold Walden
Just a haphazard collection of videos from my day to day existence.
I have been teaching kids for years and I am well aware of how frustrating some teacher can be when they can't change their teaching style to suit their audience regardless of how ineffective their current teaching style might be.
One of my real passions (apart from skateboarding) is learning new things and trying to develop my knowledge to a point where I am able to explain it to others. It doesn't really matter what the topic, if I don't know about it, chances are I will be excited to learn what the subject has to offer.
These videos will not do justice to how fascinating the subjects of mathematics, economics, physics or chemistry really are but they will hopefully help you with the technical aspects of the subjects.
If you are having real trouble with a particular subject or problem, don't hesitate to post a comment and I'll try and explain it to you as well as I can.
Hope it all helps,
Harold :)
