Science / Spiders / Defocus: defocus setting (with reference to the Gaussian focus) in the electron microscope, normally given in Angstrom units, which determines the shape of the CTF. For different settings of the defocus, diffe MORE
Science / Spiders / Pixel Size: the number of Angstroms per pixel in the digitized micrograph. Pixel size is computed as ps (A/p) = [10,000(A/u) * SR(u) * DF] / M, where ps = pixelsize, SR = scanning resolution, DF = decimation fact MORE
Technology / Cell Phones / Wavelength: The distance covered by one cycle of a wave. MORE
