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.

sean carroll: physics and the immortality of the soul

from scientific american:



'very roughly speaking, when most people think about an immaterial soul that persists after death, they have in mind some sort of blob of spirit energy that takes up residence near our brain, and drives around our body like a soccer mom driving an suv. the questions are these: what form does that spirit energy take, and how does it interact with our ordinary atoms? not only is new physics required, but dramatically new physics. within qft, there can't be a new collection of "spirit particles" and "spirit forces" that interact with our regular atoms, because we would have detected them in existing experiments. ockham's razor is not on your side here, since you have to posit a completely new realm of reality obeying very different rules than the ones we know.'

the entire piece here and at cosmic variance.
