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.

are geometry skills innate?

this is especially interesting to me, having taught CAD for twenty years.  it seems to me that geometry skills have declined drastically since the early 90s, even in basic concepts, and even among engineers.  if so much of geometry's innate, the schools are one big fail.

at BBC news:

'tests given to an amazonian tribe called the mundurucu suggest that our intuitions about geometry are innate.

researchers examined how the mundurucu think about lines, points and angles, comparing the results with equivalent tests on french and us schoolchildren.

the mundurucu showed comparable understanding, and even outperformed the students on tasks that asked about forms on spherical surfaces.'
