How many apples had fallen?
Before one of us noticed?

I really don’t care whether the story is true or not.
All I’m interested in is ‘why it took us so long’?
After all, things had fallen towards the center of the Earth since always. Eratosthenes had already calculated the circumference of the obviously round Earth back in 240 BC. And “By the 1st century AD, the spherical model was widely accepted, and Ptolemy developed maps based on a globe with systems of longitude and latitude.” According to the currently famous internet, obviously …

The way I see it, the world was not ready for it. Before Newton.
We didn’t have the ‘language’ in which to spell this new reality. And nobody really cared about the matter. Really invested into the matter, as opposed to interested about the subject…

But things change.
1492 Christopher Columbus discovered America. Trying to go to India but steering into the ‘wrong’ direction. Inaugurating the era of sailing into the unknown.
1524 The posthumous publication of Johannes Werner’s method of determining longitude and latitude by measuring the angular distance between the moon and other astronomical objects. The method was not usable at the time because the necessary data, ‘tables of ephemerides’ had not yet been published.
1543 Nicolaus Copernicus. a priest, published his famous book about how the planets circled the Earth.
1600 Giordano Bruno was burned at the stake for defending and promoting Copernicus’ ideas. The world was still not ready.
1595 – 1627 Johannes Keppler published a series of works detailing Copernicus’s heliocentric model of the Universe and elaborating mathematical tools for the job. Including a set of Ephemerides, in 1617. His work was met with mixed reactions, the opposition being mitigated by the fact that Keppler, a very religious person, never crossed any of the significant figures he came in contact with.
1687 Isaac Newton published his Principia Mathematica. Integrating and formalizing the work of many, Newton’s synthesis filled the ‘need to know’ of those concerned. While his theory was met with some philosophical opposition – Huygens and Leibniz, among others, on the practical side no one had raised any objections. Until Einstein, but that is another subject.

What happened?

People had been already sailing for some 2000 years.
But until then, it used to be a ‘craft’. Something passed on from father to son and kept, more or less, into the family.
The ‘Sea People’…
Vasco da Gama, the first European to reach India by sailing around the Cape of Good Hope, 1498, was the last of the ‘craftsmen’ who ‘discovered’ places. By sailing there using ‘the good old, time sanctioned, manner’.
Christopher Columbus, by sailing the other way around, was the first to transform this craft into an industry.
He also started the process which transformed the whole world.

Sailing and trading on an industrial scale demands a different kind of people. And transform those who embark unto the adventure.
Ancient Athens, heavily involved in sailing and trading, had invented democracy. The city continues to exist while we consider democracy to have been invented by the Ancient Greeks.
Ancient Sparta, Athens’ fiercest domestic competitor, a quintessentially agricultural society, was run as a dictatorship. Only ruins survived. And a myth…

Isaac Newton, and his readers, were able to understand gravity because they needed that knowledge.
Which was but a step in the road they were opening. For themselves and for those who followed.
Basically, what they did was to spin a new story, read ‘narrative’ out of information which was already floating around.

Are we capable of following in their steps?

For ‘only God knows what reason’ this very morning I was reminded by ‘the FB algorithms’ about a comment I made some 7 years ago.
“Democracies fend off challenges when participants value the preservation of the system—its norms and ideals and values—over short-term political gain.”

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.
