Is it possible to see a new colour?
David Hume, 1739

According to Newton, there’s no new colour to be seen.
The spectrum he had ‘split’ from what was called white light was continuous. And still is.
So, in order for us to see a new colour we should rename one of the already existing ones.

That’s according to the ‘light splitters’….

According to people who study vision – how humans see – “People can be made to see reddish green and yellowish blue—colors forbidden by theories of color perception.”

Oops!

There’s more to light than meets the eye… at the first glance, at least.
The way our brain works has something to do even with what we see of this world!
The good thing being the fact that once we understand how our brain works, we are capable of by-passing at least some of these limitations.

But what has any of these to do with ‘dimensions’?!?

I’ve argued in my previous post that having evolved as ‘runners’ we basically live in a 2.5 dimensional world. That we are biased against a proper perception of depth. And that we loath to go back and reconsider already entrenched convictions.

In this post I’ll go further and say that dimensions are tools.
Gimmicks we have invented to help us make sense of the world. And not only invented but fine tuned to fit our purposes.

We have invented length and breadth when we needed a way to impose taxes on arable land.
We have invented weight and volume when trading cereals and wine.
We have invented time when needing to pin point our position on a map while sailing around the world.
We have radically altered geometry when the old one was no longer useful.
We have even learned to adjust dimensions when speed had became fast enough to demand it.

Now, time is ripe for us to reconsider them altogether.
Opportunity, space and time.
We can make do with only three basic dimensions.
