Colour Blind/Deficent Tested and Prejusticed!

Published by Ian under Education, Personal, Science

“I just don’t see it like you” is the statement that we have all heard.

Yes that’s right, we all don’t see it the same, figuratively and literally but we want to challenge it and make everyone see it the way we do. Impossible!

We’re all different with different upbringings, genetics and culture that influences the way in which we see the world.

When I was eight years old the Department of Education nurse came and visited my school and we had a basic government health check. Amongst saying argh! and having our groins felt for problems we had a colour test. These are the standard Ishihara tests but I’ve always referred to them as confetti charts. Well I had a note to take home to my parents which said that Ian was red/green colour blind and so began my understanding of this condition.

45 56

Can you see 45? Can you see 56?

In both of these examples I can not distinguish a number.

Colour deficiency effects about 8% of the Australian male population and is carried on the female “X” chromosome. Which is interesting in that yes two of my mothers brothers were colour blind but so is my father. Which is a coincidence. How about that! I remember him buying some pink shorts once thinking that they were grey. I thought they looked fine but all the women of the family laughed, he never did wear them. Continue Reading »

Climate Debate, Options & Rational

I heard about the Greenhouse Effect in the early 80’s and I’ve been waiting to see when the general public would start to get the picture, and now we have. Now we have a debate but it’s only a public debate the scientists all agree (all but the few) but the public isn’t listening to the scientists, the tens of thousand of educated men and women who study and know all the background information that has led to their opinions.

The general public listens to the popular and noisy commentators who aren’t as educated or have vested interests elsewhere.

However… Maybe the scientists may be wrong… Sure, nothing is for certain. Look at the panic caused about the Y2K problem. Fizzier wasn’t it? What a waste of money. Although, have you ever wondered that maybe all the work done because of the concern that was created may have averted the problem so it never happened and now we have the benefits of no problem, just a few dollars spent.

Well what if the same situation plays out with global climate change?

Here is the best way I’ve come across to explain it.
