Gordon Lynn Walls
Gordon Lynn Walls (April 4, 1905 – August 22, 1962) was an American professor of physiological optics and optometry at the University of California, Berkeley Biography Walls started his education at Boston English High School. He earned his B.S. as a mechanical engineer in 1926 at Tufts College. In addition he was an undergraduate in biology and was awarded both the Goddard Prize and the Olmsted Scholarship in Biology. Walls decided not to pursue his career in engineering. Instead he entered Harvard on a graduate scholarship. His first studies dealt with photomechanical changes in the retina, laying the fundaments of his career in vision. He continued his study of the retina as a graduate student (Sc.D. in zoology, 1931) and postdoctoral fellow (1931 to 1934, Alfred G. Lloyd and National Research Council Fellowships) at the University of Michigan and as an associate in zoology at the State University of Iowa from 1934 to 1937. His interest in vision was confirmed during a fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malden, Massachusetts
Malden is a city in Middlesex County, Massachusetts, United States. At the time of the 2020 U.S. Census, the population was 66,263 people. History Malden, a hilly woodland area north of the Mystic River, was settled by Puritans in 1640 on land purchased in 1629 from the Pennacook tribe and a further grant in 1639 by the Squaw Sachem of Mistick and her husband, Webcowet. The area was originally called the "Mistick Side" and was a part of Charlestown. It was incorporated as a separate town in 1649 under the name "Mauldon". The name Malden was selected by Joseph Hills, an early settler and landholder, and was named after Maldon, England. The city originally included what are now the adjacent cities of Melrose (until 1850) and Everett (until 1870). At the time of the American Revolution, the population was at about 1,000 people, and the citizens were involved early in resisting British rule: they boycotted the consumption of tea in 1770 to protest the Revenue Act of 1766, and ...

Photoreceptor Cell
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential. There are currently three known types of photoreceptor cells in mammalian eyes: rods, cones, and intrinsically photosensitive retinal ganglion cells. The two classic photoreceptor cells are rods and cones, each contributing information used by the visual system to form an image of the environment, sight. Rods primarily mediate scotopic vision (dim conditions) whereas cones primarily mediate to photopic vision (bright conditions), but the processes in each that supports phototransduction is similar. A third class of mammalian photoreceptor cell was discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Michigan Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...
