There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

A review of reported tissue optical properties summarizes the wavelength-dependent behavior of scattering and absorption. Formulae are presented for generating the optical properties of a generic tissue with variable amounts of absorbing chromophores (blood, water, melanin, fat, yellow pigments) and a variable balance between small-scale scatterers and large-scale scatterers in the ultrastructures of cells and tissues.

Optical properties of biological tissues: a review.

Exemplary apparatus, systems, methods of making, and methods of using a rotary junction are provided. A rotary junction having multiple channels is provided herein. The rotary junction has a first coupling optic and a second coupling optic where the rotating optical fiber or other waveguide comping from the first coupling optic passes through the second coupling optics.
