  • Interesting fact: Experiments conducted in Germany and at the University of Southampton in England show that even mild and incidental noises cause the pupils of the eyes to dilate. It is believed that this is why surgeons, watchmakers, and others who perform delicate manual operations are so bothered by noise. The sounds cause their pupils to change focus and blur their vision.

I burst through where I waited long, too long, deafen'd and

I) Fixed spectrum up to dilation: Here, we fix a spectrum S , and then dilate it deterministically as the degree N grows, i.e. scale S → N S .
Random complex fewnomials, I
The result is given in Theorem 1. (II) Dilates of a random spectrum from a polytope ∆: in this ensemble, we fix ∆, choose the spectrum at random from ∆ and then dilate the resulting spectrum.
