Indirect and Direct Racism Racism is a blot on society that has transgressed mankind over hundreds of years. It is conscience of humans that few things are far superior to others. This can be explained in the detail with example of skin color‚ origin and culture which are the key factors in defragmenting the human society which eventually leads to racism. Cultural difference between various communities was one of the reason for the development of racism. As societies tries to bind itself together

detective work and forensic science have become increasingly popular among readers and enthusiasts. They demonstrate that science is an important tool in answering difficult questions regarding how the tragic assassination of President Kennedy happened for example. Forensic Science is appealing to many people because they want to be detectives to solve problems and puzzles. Today I will focus on how scientific principles embody the study of forensic science but with a main focus on how physicists and crime

Astronomy is a natural science that is the study of celestial objects (such as moons‚ planets‚ stars‚ nebulae‚ and galaxies)‚ the physics‚ chemistry‚ mathematics‚ and evolution of such objects‚ and phenomena that originate outside the atmosphere of Earth‚ including supernovae explosions‚ gamma ray bursts‚ and cosmic background radiation. A related but distinct subject‚ cosmology‚ is concerned with studying the universe as a whole.[1] Astronomy is one of the oldest sciences. Prehistoric cultures

HISTORY OF ASTRONOMY Astronomy is the oldest of the natural sciences‚ dating back to antiquity‚ with its origins in the religious‚ mythological‚ and astrological practices of pre-history: vestiges of these are still found in astrology‚ a discipline long interwoven with public and governmental astronomy‚ and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication. Ancient astronomers were able
