How cool and did you know spiders have a good side?

Did you know...
that a single strand of this spider's silk

can help generate this diffraction pattern over the interferogram shown above, corresponding to N = 3 slits, used in optical communications in free space, between spacecrafts, atom optics, Fourier imaging, optical computing, and quantum computing? I need to read more about the N-slit interferometer....

St. Albert the Great would love this!
