new photo blog

i started this blog in 2006, and it's shifted along with my interests through the years. it's been witness to a lot of learning for me...

still, i feel that i need a home for my photography -- so from now on, i'll be posting my pictures on the journal on my reworked website. if you like my photos, you might decide to follow me there!

my first post is here -- check it out!

as for this blog, i'm not sure what will happen. i don't think i'm willing to let it go, and certainly i'll keep it as an archive, but i need some time to figure it out.

for those of you that pop in from time to time, thanks for the visits and encouragement.

our world is increasingly fragile -- and cosmos is more relevant than ever.

the introduction to carl sagan's cosmos: the shores of the cosmic ocean

the size and age of the cosmos are beyond ordinary human understanding. lost somewhere between immensity and eternity is our tiny planetary home -- the earth. for the first time, we have the power to decide the fate of our planet and ourselves. this is a time of great danger, but our species is young and curious and brave, it shows much promise. in the last few millennia we have made the most astonishing and unexpected discoveries about the cosmos and our place within it. i believe our future depends powerfully on how well we understand this cosmos in which we float like amote of dust in the morning sky.

we're about to begin a journey through the cosmos. we'll encounter galaxies and suns and planets, life and consciousness, coming into being, evolving and perishing. worlds of ice and stars of diamond, atoms as massive as suns, universes smaller than atoms. but it's also a story of our own planet, and the plants and animals that share it with us. and it's a story about us, how we achieved our present understanding of the cosmos, how the cosmos has shaped our evolution and our culture, and what our fate may be.

we wish to pursue the truth no matter where it leads, but to find the truth we need imagination and skepticism both. we will not be afraid to speculate, but we will be careful to distinguish speculation from fact. the cosmos is full beyond measure of elegant troves, of exquisite interrelationships, of the awesome machinery of nature.

the surface of the earth is the shore of the cosmic ocean. on this shore, we've learned most of what we know. recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting. some part of our being knows this is where we came from. we long to return, and we can, because the cosmos is also within us. we're made of star stuff. we are a way for the cosmos to know itself. the journey for each of us begins here. we are going to explore the cosmos in a ship of the imagination, unfettered by ordinary limits on speed and size, drawn by the music of cosmic harmonies. it can take us anywhere in space and time. perfect as a snowflake, organic as a dandelion seed, it will carry us to worlds of dreams, and worlds of facts. come with me.

  1. I have just received, this morning, my new copy of this series as I keep giving my own copy away to family and friends. It is a life changing experience to watch and listen to Carl Sagan. Thanks for posting this clip.
