Hinduism

Hinduism is an ancient religion of India and the oldest religion in the world.
Hindus regard the Vedas which was composed around 1500 B.C. as central to the hindu tradition.
Hinduism is like an ocean of the combined knowledge of various rishis, sages, and saints. It was they who gave the religion the depth and complexity for which it is known today
Hinduism is a way of life, there is no fixed name for Hinduism; some call it Sanatana Dharma, some call it Bhagawat Dharma, etc. There was no name “Hindu” in old scriptures but later invaders of India named people here as Hindu because they used to live on the banks of the river Sindhu.

History of breakfast cereals.

y
cherriosThe first modern and commercial cereal foods were created by the American Seventh-day Adventists. The Adventists formed the Western Health Reform Institute in the 1860s. The Institute was later renamed the Battle Creek Sanitarium after its location in Battle Creek, Michigan. The Adventists manufactured, promoted, and sold wholesome cereals.
Cereal or grain is a member of the grass plant family, with starchy seeds used for food. Common cereals are: wheat, rice, rye, oats, barley, corn (maize), and sorghum.
Will Keith Kellogg
Will Keith Kellogg was the founder of the W.K. Kellogg Foundation, founded in 1906. In 1894, Kellogg was trying to improve the diet of hospital patients. He was searching for a digestible bread substitute using the process of boiling wheat. Kellogg accidentally left a pot of boiled wheat to stand and the wheat became tempered (soften). When Kellogg rolled the tempered or softened wheat and let it dry, each grain of wheat emerged as a large thin flake. The flakes turned out to be a tasty cereal. Kellogg had invented corn flakes.

X-Rays and the Tungsten filament

All light and radio waves belong to the electromagnetic spectrum, and are all considered different types of electromagnetic waves, including:
  • microwaves and infrared bands whose waves are longer than those of visible light (between radio and the visible)
  • and UV, EUV, X-rays and g-rays (gamma rays) with shorter wavelengths.
The electromagnetic nature of x-rays became evident when it was found that crystals bent their path in the same way as gratings bent visible light: the orderly rows of atoms in the crystal acted like the grooves of a grating.

Medical X-rays

X-rays are capable of penetrating some thickness of matter. Medical x-rays are produced by letting a stream of fast electrons come to a sudden stop at a metal plate; it is believed that X-rays emitted by the Sun or stars also come from fast electrons. The images produced by X-rays are due to the different absorption rates of different tissues. Calcium in bones absorbs X-rays the most, so bones look white on a film recording of the X-ray image , called a radiograph. Fat and other soft tissues absorb less, and look gray. Air absorbs the least, so lungs look black on a radiograph.

Wilhelm Conrad Röntgen - First X-ray

On 8 Nov, 1895, Wilhelm Conrad Röntgen (accidentally) discovered an image cast from his cathode ray generator, projected far beyond the possible range of the cathode rays (now known as an electron beam). Further investigation showed that the rays were generated at the point of contact of the cathode ray beam on the interior of the vacuum tube, that they were not deflected by magnetic fields, and they penetrated many kinds of matter. A week after his discovery, Rontgen took an X-ray photograph of his wife's hand which clearly revealed her wedding ring and her bones. The photograph electrified the general public and aroused great scientific interest in the new form of radiation. Röntgen named the new form of radiation X-radiation (X standing for "Unknown"). Hence the term X-rays (also referred as Röntgen rays, though this term is unusual outside of Germany).

William Coolidge & X-Ray Tube

William Coolidge invented the X-ray tube popularly called the Coolidge tube. His invention revolutionized the generation of X-rays and is the model upon which all X-ray tubes for medical applications are based. Other inventions of Coolidge: invention of ductile tungsten
A breakthrough in tungsten applications was made by W. D. Coolidge in 1903. Coolidge succeeded in preparing a ductile tungsten wire by doping tungsten oxide before reduction. The resulting metal powder was pressed, sintered and forged to thin rods. Very thin wire was then drawn from these rods. This was the beginning of tungsten powder metallurgy, which was instrumental in the rapid development of the lamp in
