The Chemistry of Photography Michael Shorrock The chemistry of Photography Summary: Joseph-Nicephore Niepce took he word’s first photographs in 1824. Many people don’t know that he was the person who invented photography; they think that a Frenchman named Daguerre was the inventor but he got the idea from Niepce. Jacqueline Belloni, a chemist at the University of Paris-South at Orsay, is doing research on “holes” in halide ions. The problem with “holes” is that they gobble up light-generated ele

The Chemistry of Photography1
The Chemistry of Photography1 Photography is a very complex form of art, which uses standard chemicals and scientific equations. It is a chemical reaction, which occurs when light hits a film or paper emulsion. An emulsion is part of the film or paper, which is very sensitive to light. This is also the part where the chemical reaction takes place. In an emulsion, are small crystals of silver halide, silver bromide, silver chloride, or silver iodide [Eaton, George]. These chemical crystals react

the development of the atomic theory The Greek concept of atomos: the atom Around 440 BC leucippus of Miletus originated the atom concept. He and his pupil, Democritus of abdera refined it for future use. Their atomic idea has five major points. All original writings of leucippus and Democritus are lost. The only sources we have for there atomistic ideas are inquotations from other writers. Democritus was known as the laughing philosopher because he enjoyed life so much. At this time Greek phi

In “The Double Helix,” James tells the story, both funny and serious, of all his trials and tribulations leading up to the famous discovery. James starts out with his fantasy of someday solving the great mystery surrounding the structure of DNA. He realizes from the very beginning his competitors in this great race: Maurice Wilkins (x-ray diffraction expert), Rosy Franklin (Information

The History of Organic Chemistry
The History of Organic Chemistry Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eightee

A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their contain

Particularly in our hiring of public school teachers, we tend to avoid notions of serious discernment, of picking the very best in our society to become our teachers, and we accept that the most talented of our young people will gravitate to other fields. Overcoming this acceptance of mediocrity in teacher recruitment and retention represents

By finding out what those colors are, you can figure out what the composition of the star is, and how much of each different element the star is made up of. This is done using spectroscopy. Spectroscopy is using a spectrometer to find the spectrum. The distribution of energy emitted by a radiant source, as by an incandescent body, arranged in order of
