An Explanation of Direct And Inverse Proportion

Editing In Progress

Introduction

At least one of my other posts How Distance Reduces The Power of Radio Waves (not yet published) requires an understanding of mathematical proportionality. In particular it requires an understanding of Inverse Proportion. So I have written this article to try and clarify it. It gives an explanation of the two types of proportion, otherwise known as variation, which are:

  1. Direct Proportion,
  2. Inverse Proportion otherwise known as Indirect Proportion.

Using A Milk Bottle As A Plant Pot Reservoir

Introduction

If I water plant pots in dry weather the water runs over the top of the soil to the edge of them.

When the water gets to the bottom of the pot it runs quickly through any shards, stones, etc., used for drainage and pours out of the drainage holes. So, I needed a Plant Pot Reservoir to retain water and feed the soil slowly.

Draping A Christmas Garland Over A Mirror or Picture

Introduction

It was a few Christmases ago when my wife and I first draped a Christmas Garland over the mirror in our lounge and another over the mirror in the hall.

The garlands we bought were fashioned very much to our liking. They just looked like Christmas and became one of those purchases made without knowing exactly what we would do with them.

This post explains how to fix a garland to the top of a hanging mirror, or picture frame, so it remains in place over Christmas and can be reused the following year.

How I Hung My Vertical Radiator In The New Lounge

I hung my vertical radiator in the new lounge while the builder of my extension and his plumber were busy doing other work. They let me do this because I explained my concerns about its weight and agreed to try fixing it by their method.
