The process of shredding was used successfully several times during the analysis phase of the human genome project. [1] The first phase of the human genome project is called the "shotgun phase". During this phase human chromosomes are 1). Divided into DNA segments of equal size and then 2). Subdivided into even smaller DNA segments.
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal.

The history of X-ray microscopy can be traced back to the early 20th century. After the German physicist Röntgen discovered X-rays in 1895, scientists soon illuminated an object using an X-ray point source and captured the shadow images of the object with a resolution of several micrometers. [2]
X-rays can provide a better picture of plaster casts and other works that rely on internal supports. However, size and mobility can often affect whether or not radiography is an option for sculptural works. X-rays can also identify cracks and previous repairs to glass and ceramic materials, which is important for assessing the condition. [4]
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.
Focal plane tomography uses the fact that the focal plane appears sharper, while structures in other planes appear blurred. By moving an X-ray source and the film in opposite directions during the exposure, and modifying the direction and extent of the movement, operators can select different focal planes which contain the structures of interest.
An X-ray of Tutankhamun's skull, the arrow pointing to a possible cause of death 1905; Heinrich Ernst Albers-Schoenberg used the radiological method to examine an Egyptian mummy. He discovered that there was a substance in the thorax and pelvis which had most likely been placed there for mummification purposes.
