limit : n : a number or point L that is approached by a function f(x) as x approaches a if, for every positive number , there exists a number such that | f(x)-L | < if 0 < | x-a | < . Also called limit point, point of accumulation. if anyone has a clue what that up there means, please leave a comment explaining it. there is a reason they tell you not to stare at bright lights or the sun, and going blind has little to do with it. lay back on the grass, and look up in the bright sky. half lid your eyes like a Buddha, to the point where the light starts to bend and dance between your eyelashes. open the eyes a little more, and look at the pattern of the images dancing before you. that is the back of your eye, your retina. ease your eyes closed a sliver, a half an intention and you begin to see the structures that make up the universe, all spread out in the light playing in your eyelashes. that is the real reason they don't want you staring at the sun, or a light bulb. also note, it is nearly impossible to do this with a flickering light source such as a telivision or computer monitor. as one approaches the point where the light shatters and displays reality, a flickering source such as a tv blurs, softens, and all you can see is the flickering. perhaps that is why telivision rots ones brain. that is the real reason they do want you staring at the telivision. I can close my eyes and see worlds. if there was a way to hook directly into...I dunno, a computer, or a reality, then I could build an entire universe using but my mind. perhaps some day I will be able to do so, moulding reality into new shapes. 72 hours until we move.
