The idea that reality begins in the imagination and that we have the power to create our own realities.

What am I trying to say: Reality - Illusion Being able to access other realities – illusion? In darkness I heard voices of the past. How strange. They cannot exist there. Those voices are mute, dead and gone. And yet, I hear them... They murmur through sunlit hallways, measured out by the beat of shoe-soles on stone, rising in intonation and nestling in the crevices of Plateresque relief still sharp with newness and sunlight. But that cannot be reality. Those hallways are worn with age and far away. And yet, I saw them clear as day… Where are the hallways? In my mind, and in my mind alone? Where are these voices? [I let the thought lie, glance away, and pick up my guitar.] I pick up my guitar and begin to play. My fingers warm up, my mind relaxes, and I sink into the sound. Soon I am not just practicing, but playing. Am…E…Dm… a note rings through my head, and I fumble across the frets to find it… ahhhh, F, that’s it. Am, E, Dm, F… the notes unwind in my mind, my fingers follow where they go, and suddenly a song has been composed – a story told. [I pause and my gaze drifts out the window.] a song born into reality – but when? Was it real in the moment that I heard it in my head, or only once I found the strings and strummed them? And if, while in my mind, it was not real, how is it that I heard it? One thing is certain: without the tune that reverberated in my mind, the song I strummed would not have come to be. Reality begins in the imagination. Did Columbus know this? Is that why he sailed so far afield? But more than that knowledge he had the ambition/aim/devotion/(and balls) to a goal to act on it. Devotion to an aim. Go after something! Stop wasting time staring at a blank screen, tabula rasa. If you don’t have all that you dream, go after it – the line between illusion and reality is thin. Create you own reality, participate in that reality, and who knows what mountains you can move. Make something of yourself! Do what you will, despite what others say You don’t have to know exactly what you are doing – that is why you are doing it! Fortune favors the bold – find that which you seek Find strength in something Reality begins in the imagination, and perhaps it ends there too. It is where Zacuto, Nebrija Cortez, and Columbus have ultimately come to live. (And they live there not because of their deeds. Those lie dormant in history books. They live in my imagination because of their personalities). But it is the in-between, the strumming, sailing, and knowing, the life-propelling devotion, that shapes the world, that makes the difference. We must first think things up and then test them to be true, test them for validity. And this process , the process of aquiring knowledge and going after the goal, is much more important than the attainment of that goal. We create our own realities. I hear the voices in my mind – tow the line between insanity and genius.
But nonetheless real. The world is in constant flux – empires changing Devotion to an aim. Go after something! Stop wasting time staring at a blank screen, tabula rasa. If you don’t have all that you dream, go after it – the line between illusion and reality is thin. Create you own reality, participate in that reality, and who knows what mountains you can move. Make something of yourself! Do what you will, despite what others say You don’t have to know exactly what you are doing – that is why you are doing it! Fortune favors the bold – find that which you seek Find strength in something (, hold dear
Its many uses include finding and predicting the positions of the stars and the sun; determining local time given local longitude, and vice-versa; and surveying and triangulation. An astrolabe consists of a hollow disk, called the mater , which is deep enough to hold one or more flat plates called tympans , or climates. A tympan is made for a specific latitude and is engraved with a stereographic projection of lines of equal azimuth and altitude representing the portion of the celestial sphere which is above the local horizon. The rim of the mater is typically graduated into hours of time, or degrees of arc, or both. Above the mater and tympan, the rete , a framework bearing a projection of the ecliptic and several pointers indicating the positions of stars, is free to rotate. Some astrolabes have a narrow rule which rotates over the rete, and may be marked with a scale of declinations.
