According to info received by StampNews.com Israeli Post is ready t release and put into circulation a special stamp celebrating two important events – the International Year of Light 2015 and the 2013 Nobel Prize in Chemistry. The issue has been already designed and will become available for purchasing on the 10th of February.
This stamp marks two events that have much in common. The first is the 2013 Nobel Prize in Chemistry that was jointly awarded to Martin Karplus (Harvard University), Michael Levitt (Stanford University) and Arieh Warshel (Universityof Southern California) for the development of multi-scale models for complex chemical systems.
The prize recognized their revolutionary contributions during the years 1968–1976, which created the new field of computational molecular biophysics and provided new approaches and techniques for understanding complex biological molecules. Their approach changed the way we think about proteins and defined a new area of science, which has influenced and inspired many other fields.
The second event is the International Year of Light 2015, which was declared by the United Nations to celebrate the light sciences, light-based technologies and their importance to humankind.
The Israeli component of this Nobel Prize is significant.
The right side of the stamp features the protein Rhodopsin, which is a bundle of seven helices connected to each other by peptide loops. This protein, which is embedded within the cell membrane, binds retinal, a small light-sensitive molecule shown as a group of grey spheres that represent atoms. The left side of the stamp exhibits the Schrödinger equation, which is the most fundamental tool of quantum mechanics.
Nobel Prize laureate Erwin Schrödinger formulated this equation in 1925 as a way to describe various states of atoms and molecules, opening the door for the science of theoretical and computational chemistry and physics.
The stamp tab features the logo of the International Year of Light as well as a schematic representation of the two major types of light-sensitive cells in the human retina: the rods (in yellow) and the cones (in blue, green and red).
The rods are responsible for black-and-white vision and the cones are responsible for color vision. The human eye contains three types of cone cells, which discern red, green or blue light. All of the retinal cells translate the light stimulus to chemical changes and electrical impulses, which are transmitted to the vision centers in the brain via the optic nerves.
