LEGO Book Update

I have updated the online book "Exploring the Nanoworld with LEGO Bricks" and have posted it online at: http://mrsec.wisc.edu/Edetc/LEGO/index.html.  New sections include scanning electron microscopy and dialysis.  In the dialysis demonstration pictured, small bricks can be shaken through channels in the divider, but not the larger bricks.
