Re: [Phys-l] A demo for biologists?

Dear Bernard,
I would do this, If I had a microscope at home. And using a sensitive scale, if I had it, I would determine the thickness in terms milligrams per square centimeter. Converting to microns would be trivial if density were known. For a rough estimate, as in this case, I would assume that the density is 1 g/cm^3.

The thickness was probably several
microns (I have nothing to measure the thickness at home).



No! You do. place a piece of it at the end of two microscope
slides so tother ends are in contact illuminate the slides w/ your
LASER from far away and count the FECO.
