The magnitude of historical earthquakes can be measured in : Richter scale How the radioactivity was discovered ? Describe the experiment which leads to the discovery of radioactivity . Henri Becquerel was behind the discovery of radioactivity . He discovered this , while he was dealing with phosphorescent materials . When exposed to light Phosphorescent materials glow . Henri connected this glow with X-rays . He performed an experiment by placing some phosphorescent salt on a photographic plate . This was in vain and made use uranium salts in...

The cyclotron and the fight against cancer Insert Your Name Course Instructor Course Name 22 July 2010 The cyclotron and the fight against cancer Introduction One of the benefits of technological advancements is improved quality of life . Medical breakthroughs through which many illnesses have been demystified and their effects mitigated can mostly be attributed to improvements in technology . It is now possible to operate on a patient 's inner body without having to cut the body open . Similarly , many other...

The linear accelerator Introduction The late 19th century discovery of X-rays led to revolution in medical science that would culminate in the medical advancements we have today . The capability of X-rays to penetrate the human skin became a very exciting adventure to most scientists at the time they were being initially explored . The excitement was however short-lived because soon after , it was discovered that X-ray penetrations carried potential health risks . Consequently , focus started shifting to the safety of the rays...

quantities of antimatter in the resulting particle jets , which are immediately annihilated by contact with nearby matter . It may similarly be produced in regions like the center of the Milky Way Galaxy and other galaxies , where very energetic celestial events occur (principally the interaction of relativistic jets with the interstellar medium . The presence of the resulting antimatter is detectable by the gamma rays produced when positrons annihilate with nearby matter . The gamma rays 039 frequency and wavelength indicate that each...

idea (Also , the particle theory of light went out of favor during the nineteenth century it seemed that everything could be explained by the wave theory , and according to the wave theory , it was not clear that light would be affected by gravity at all ) In fact , it is not really consistent to treat light like cannonballs in Newton s theory of gravity because the speed of light is fixed (A cannonball fired upward from the earth will be slowed...
