Pioneers in Optics: Galileo Galilei

Galileo Galilei and the property of naming light spots.

Galileo's eye: a new vision of the senses in the work of Galileo Galilei.

Reflections on the senses, and particularly on vision, permeate the writings of Galileo Galilei, one of the main protagonists of the scientific revolution. This aspect of his work has received scant attention by historians, in spite of its importance for his achievements in astronomy, and also for the significance in the innovative scientific methodology he fostered. Galileo's vision pursued a ...

`-conformal Galilei algebras

Inequivalent N = 2 supersymmetrizations of the `-conformal Galilei algebra in d-spatial dimensions are constructed from the chiral (2, 2) and the real (1, 2, 1) basic supermultiplets of the N = 2 supersymmetry. For non-negative integer and half-integer ` both superalgebras admit a consistent truncation with a (different) finite number of generators. The real N = 2 case coincides with the supera...

Pioneers in biomedical optics: special section honoring professor Ashley J. Welch, University of Texas at Austin.

Born and bred in Ft. Worth, Texas, he spent his entire career in the Lone Star State. A.J. graduated from Texas Technological College now Texas Tech University in Lubbock, Texas, with his BS degree in electrical engineering in 1955. He was raised primarily by his mother who early on instilled in him the value of a good education. With obvious talent in science and math, engineering was the thin...
