Though denigrated by some outside academia and research, she embraced knowledge for its own sake and what better way to honor that than reveling in the intricacies of the brain? If there were any answers to the human condition, if an immortal soul made its home anywhere, it was in its spongy gray folds.
These computer simulations try only to duplicate the interactions between the cortex and the thalamus. Huge chunks of the brain are therefore missing. Dr. [Dharmendra] Modha understands the enormity of his project. His ambitious research has allowed him to estimate what it would take to create a working model of the entire human brain, and not just a portion or a pale version of it, complete with all parts of the neocortex and connections to the senses. He envisions using not just a single Blue Gene computer [with over a hundred thousand processors and terabytes of RAM] but thousands of them, which would fill up not just a room but an entire city block. The energy consumption would be so great that you would need a thousand-megawatt nuclear power plant to generate all the electricity. And then, to cool off this monstrous computer so it wouldn't melt, you would need to divert a river and send it through the computer circuits.It is remarkable that a gigantic, city-size computer is required to simulate a piece of human tissue that weighs three pounds, fits inside your skull, raises your body temperature by only a few degrees, uses twenty watts of power, and needs only a few hamburgers to keep it going.

A typical Celestine will devote a large proportion of their time to passing through the inscribed sectors of the planet studying the writings, either alone or accompanied by companions with whom to share comments. This is a favourite pastime among them, and as they travel towards the boundaries of the inscribed regions they can watch the ongoing work of those Celestines that have been chosen to record their ideas _ tirelessly twisting, pausing to gather energy, then exerting themselves again; painstakingly working the same patch of dust several thousand times over to shape each individual furrow; to capture, symbol by symbol, the knowledge they have contributed to the Celestine corpus. There is great pride and precision, as well as immense labour, in their toil. Before they commence work, the piece of ground that will house the writing will be chosen very carefully for its aspect. Then, the most favourable angle to the light will be calculated, for the orientation of the wording. The language used is of the most poetic and grandiose sort, quite different from the vernacular, and the symbols themselves are embellished with flourishes, extravagances and curlicues that are unique to the creator. Celestines love to observe this work, which constitutes the pinnacle of their art and of their ceaseless thought-endeavours, and embodies their very reason for being.
