Why the Everyday World makes Sense

Some people seem quite confused by the discrepancies between microscopic (quantum) reality and macroscopic (everyday) reality. The fact that the quantum level doesn't follow our normal logic has caused a lot of trouble for scientists (and only slightly less for the general public).


How can a level of reality, that we experience in our everyday lives, make perfect sense when it is generated from a completely illogical, counter-intuitive level beneath it?


The answer has to do with the way we are looking at the problem: macroscopic reality must make intuitive sense. Our minds have developed precisely in order to form predictions about the everyday world. We experience reality at the level of tables, chairs, grass and human actions willed by other minds. Our grip on the world is at the macroscopic level, and over the millenia individual consciousness has developed in order to understand the world at the level where it is active. Our sensory apparatus filters and interprets the world, applying forms and categories to the seething mass of undifferentiated data which bombards us. From this, we isolate and extract narrative threads which allow us to act effectively in the world. We cannot dispute that there are other events going on that we fail to comprehend. There are other narrative streams which simply don't fit into our minds, which don't make it through the logic filter, and so we don't connect isolated events which, seen from another dimension of thought, would be a clear process of cause and effect.


For example, we think in only one temporal direction. We find it exceedingly difficult to view cause and effect running from the present to the past. But doesn't this say more about our minds and the way they work, than about reality itself?


The reason the quantum world doesn't make sense in the same way the day-to-day world does, is not because of a structural shift between two levels of reality; it is because our minds suddenly reach 'home-ground' when we return to the everyday world.


The big question which this is leading up to, of course, is of the relationship between 'objective reality' and the subjective experience. But this is a topic for another blog.

Programmable Matter

So, scientists are always complaining that their funding keeps getting cut, but when they do get money what do they spend it on?

Well apparently, new ways of manipulating elementary particles to create previously 'impossible' forms of matter...and then, they find ways to change the kind (and therefore properties) of matter, at the flick of a switch.

Okay, so it only works so far in two dimensions but i still think the ability to create 'artificial atoms' and change their structure at will is pretty impressive.

The practice (this isn't a theory. this is actually happening) draws on quantum theory, and also has significant applications for quantum computing as if we can control the structure and flow of electrons between these 'artificial atoms' then the size of silicon chips no longer limits processing power.

Computer scientists have placed the date 2020 as both the point when we will be unable to further enhance computer power by reducing the size of the components....and the point at which computers will begin, if their trajectory continues, to outstrip humans in both intelligence and humanness.

I should make clear at this point that the possibility of computers actually taking over from humans; ie, becoming self-aware and beginning to manipulate their own nature and therefore destiny, while being science fiction to most of us, is treated as a virtual certainty (no pun intended) by professional computer scientists at institutions actually conducting the research and defining the future of computers.

My own thoughts? Let's take a look around. Humanity faces some very serious decisions over the next decade. But it seems to me like we've already given up on progressing beyond our naive, childish phase, our bullying, judgmentalism and irreperably selfish ways will be the end of us. What makes me most sad, is that some people have been trying to show us our potential for centuries.

"A great miracle, O Asklepios, is man" said Hermes Trismegistus two centuries ago. Along with every other mystic, he (or whoever wrote the Gnostic treatise Asklepios) understood that divinity is not outside of man..it is within. It is our own adulthood, waiting for us to mature sufficiently and take on the responsibility that this demands.

This is not an abstract, it is a fundamental to do with our own nature, and it relates to every individual on earth. We all have the responsibility of this decision - to grow up and become who we really are, or stay asleep, daydreaming and lost in transitory distractions...and let the mantle of evolution pass onto another, more willing entity.
