Weird connections : Necessity, Evolution and Learning

What did those ancestors of ours thought when they drew bisons on the cave walls, perhaps in the light of a burning wood. Perhaps there were others looking at awe at this unique phenomenon of capturing, in a completely new sense, what they see running and throbbing amidst the landscape. Perhaps they were dumbstruck that something like this can happen. Perhaps the first artists in the history of mankind were shunned from the group. Or, perhaps the artists were hailed as supernatural beings. Perhaps it was at this point of time in human history that the idea of creation most poignantly emerged separately from the history of necessities that made man. Necessity is said to be the father/mother of all inventions. Necessity is also the reason there are discoveries. Had there been no urge to find new sea-routes, the landmass we call America would have never been discovered. (But that is another story altogether). What if we go a step further and say, necessity is also the cause of evolution?

Evolution is cryptically defined as the Darwinian idea of the survival of the fittest. It is not the survival of the strongest. It is not the survival of the most ferocious. It is a poetic truth actually. What can be more poetic than the radical cocktail of the element of chance (not so radical in the post- Quantum era though) and the primal urge of survival? Had the human ancestors not felt the radical urge to continue existing in a world that is naturally more powerful than humans ever thought of being, the history of mankind could have been lost in the voids of time.

As mankind trekked through its own history, Darwin's adage was seen as a scientific truth, detached from the reality of our worlds. Power became the stronghold of survival. And humans believed it; they continue to do so. Histories and myths of once great and thriving, and, now extinct civilisations are not very hard to find: the Harappasn civilisation, the ancient Egyptian, Greek,  Roman civilisations, the native American civilisations. And yet, man believes that, that is different. Humans believe that they exist as a continuity of the past civilizations. In terms of genetics, it may be so. In terms of the basic science of Darwin, may be not. 

In  an Old- English poem, a refrain occurs : "That has passed and so shall this". It was a refrain in an elegy, a poem about loss, a poem of lamentation. In that context, this is a hopeful, stoical view of life. Darwin's theory of survival of the fittest seems to be a variation of this refrain. What has survived in pre-historic eras - the wide variety of dinosaurs, the mammoths, the Archaeopteryx (possibly the first bird)- is lost in this present time. What is in this time, may as well be lost in some future time. And yet, Darwin's theory is but a story in the history of science.  

Does this mean we have a meaningless existence? Existence is the meaning we give to this present moment; what meaning it will have in future times we can only speculate. The most profound quality thatthis rather young species in this world needs is perspective.

Herein, interjects the history of the human civilisation and our ongoing discussion of learning. There are differences between what was done, what can be done and what can't be undone. The human learning process does not initiate the mind in seeing the difference between each of these. Education in this modern world is still largely something like the factory production system. There is no  one better to explain this than Ken Robinson in his admirable light-hearted and yet forceful way.

Puja Chronicles: Actual/Virtual

No one spelled it out. And yet, it was there. Like a star. 

I always thought I had a non-scientific mind. When I looked up at the clouds, I could never recognise whether they were cumulus or stratus. I saw images. Of elephants, of Archaeopteryx (I loved to figure this out specially), of flying castles, of Santa Claus's face. I believed I was prone to imagination than rational thinking. Then, a few years into high school, and Physics introduced me to the world of constellations. Individual stars being a part of an image in the sky. I was baffled to know, science needs imagination. 

That was the beginning (I guess) of questioning what seems to be 'real'. The absolute versions held ground for a long time since then, but the foundation of the idea of the 'absolute' had started eroding.

Far away in the distance, there used to be a ball of gas. It started 'living' - burning itself up in order to radiate light/energy/life. It performed the balancing act of gravity and expansion. And then it had to die. It became a 'dwarf' or an eternity called 'black hole'.

Is the star there as I see it now?

I can see it twinkling! It is actual, I guess. But, it may have died and its light is still crossing the seas of the universe to reach me. Does that make it virtual?

Feeling homesick on a day when celebrations of a mother goddess fill my mother's house with laughter and joy. Before the deity leaves the threshold of the home, I skype home. I dress up as a traditional Bengali married woman - complete with sari, the jewellery, the vermillion on the forehead. I have arranged a candle, the vermillion (sindoor, the mark of marriage), a flower, an Arab sweet, a small glass filled with water on a dish. The camera looks into the face of the deity. From across the oceans, I hold the platter in my hands and perform an action that every married woman does at the end of the festival for any Hindu goddess. I boron (a ceremony performed to cordially welcome) the deity. 
 
boron

[It is strange that the festival begins and ends with the same custom of boron. Even when the deity is taken away for the immersion in water, marking the end of the festival, it is wished a good journey and an invitation to return in the next cycle of time.]     
What I did was in real time but not in real space. Does that make it any more virtual or any less actual? 
I do not know. The conventions of understanding the time and the space are somehow soiled by the sense of happiness I had at the end of the act. I felt  as if I participated actively in the joy that exuded in the household for the past few days. I felt the warmth of having a family filling me in this chilly land. That is the perspective I choose.

An Aside ...

As this blogger tries to perpetrate her present thoughts on the uncanny connective thread between the disparate ... here's food for thought ... and, for the imagination ...



If you like this video ... go ahead and have a peak at the theory behind the making of it at Nature by Numbers by Cristóbal Vila . The blogger did not know about the complex mathematical theories referred to. She needn't either. The video just re-validated her idea of this invisible thread of similarity underlying apparently disparate things or ideas...
