we've been all over the world we've been
to all the major universities a lot of
time at mit and stanford and caltech and
off to europe to switzerland and england
for example for the episode called
smaller making stuff smaller we're
looking at the principle that the
smaller you get the more powerful you
can get so we're looking at
um
nano bs for example these are sub
microscopic bees that deliver drugs
directly into your cancer cells nothing
else they find the cell
kill it um crazy stuff
and to introduce the idea of
nanotechnology we went to visit some of
the cathedrals of europe where stained
glass has been in place for a thousand
years using nanotechnology these guys
just didn't have a little european word
for it but that's what they're doing
turns out that if you file up gold until
the particles are really really small
you can mix it to your glass to produce
what color anyone anyone
red what sense does that make you can
take copper file it down really small
put it in your glass and it makes
blue i mean what so the idea behind
nanotechnology is that at a certain
scale
when an ob when a material is so small
its properties change it becomes
more magnetic less magnetic a different
color a different weight whatever
than it does in the bulk form so you can
just do incredible alchemy at that size
you
