How Heinrich Hertz Changed The World Of Radiology

Luis Walter Alvarez was born on June 13th in the year 1911 in San Francisco but at that time no one knew he was going to be a world renowned physicist. As a adolescent, his love for science, technology and machines was evident, but no one guessed he would make something out of it. He and his father (Walter C. Alvarez) built a radio when he was eleven, this was when the radio was still a new invention. Graduating from The University of Chicago in 1932 and earning his phD in 1936 was not the end of his scientific interest. Luis Walter Alvarez continued to study science and physics. He was credited with many necessary discoveries about subatomic particles for which he earned the Nobel Prize in physics. His work did not stop there. He was a co-developer in the creation of the “ground-control approach system” for aircraft during the 1940’s. Luis Walter Alverez had a very significant role in the development Manhattan Project, in which he suggested the technique used for the detonation of an atomic bomb. He was member of the National Inventor's Hall of Fame. On top of all this he held ownership of the patents for over 30 inventions including radar systems and the bubble chamber.

Einstein has brought many insights of life including the theory of the speed of light, which has led to the special theory of relativity that molded the way science, is today. “For example, various experiments, including the Michelson-Morley experiment, failed to measure the expected changes in the speed of light relative to the motion of the Earth. Due to this Einstein recognized that light has a measured speed that is independent of the speed of the observer” (“Albert Einstein.” 4). “Einstein showed in 1907 that mass is related to energy by the famous equation E=mc^2, which indicates the enormous amount of energy that is stored as mass, some of which is released in radioactivity and nuclear radiations, for example in the sun” (4).This enabled Einstein to be able to start and finish the general theory of relativity.

1. In 1895 the discovery of X-rays by the German scientist of physics, Wilhelm Roentgen, created an amazing step forward in the history of medicine. For the first time ever, the inner workings of the body could be made visible without having to operate.

1895 – X-rays were discovered accidentally by physicist Wilhelm Conrad Rontgen. Rontgen was working on a experiment and testing whether cathode rays could pass through glass. He noticed that a nearby tube emitted fluorescent glow of crystals. The air in the tube was released, high voltage applied, the same tube emitted a fluorescent glow. When Rontgen covered the tube in a heavy black paper, a green light could be seen. He concluded that a new light ray was being broadcast. Rontgen discovered that the light was very powerful and the same ray could pass through human tissue, but not through bones and metal objects. Medical applications were soon to follow.

During a study done by German Scientist Heinrich Hertz, he discovered radio waves. In 1985 Guglielmo Marconi used radio waves to create the first wireless telegraph which is now known as the radio. His invention was first done in his parents attic. Marconi used radio waves to transmit Morse Code and it worked. The Nobel Prize in Physics was awarded to Guglielmo Marconi and Karl Ferdinand Braun for the development of the wireless telegraph. Marconi and Braun shared the Nobel Prize equally.

If you have thought about becoming a Radiologic Technologist, someone who performs imaging examinations, but do not know if it is the right choice for you. This paper will inform the reader as to how to become a Radiologic Technologist, their job description, ranging from the work settings to the kind of patients they deal with, some of the challenges and rewards, including their salary as well. At the end of this paper you should be able to make up your mind on becoming one or not.

X-rays were discovered by accident in 1895 by the German physicist Wilhelm Conrad Roentgen. Roentgen was already an accomplished scientist with forty-eight published papers. He had a reputation among the scientific community as a dedicated scientist with precise experimental methods. Roentgen had been conducting experiments at the University of Wurzburg on the effect of cathode-rays on the luminescence of certain chemicals. Roentgen had placed a cathode-ray tube, which is a partially evacuated glass tube with metal electrodes at each end, in a black cardboard box in his darkened laboratory. He sent electricity through the cathodre-ray tube and noticed something strange his laboratory. He saw a flash of light

One achievement of Einstein’s was the human understanding of light. His interest in light came at an early age. In 1905, he conducted his first “Thought Experiment” and formed the special theory of relativity which said that light is constant. This contradicted what other scientist of his time had thought. It also said that nothing can travel faster than the speed of light at 186,000 miles/second, and that light travels at the same speed no matter where the source is coming from. Another

The discovery of x-rays revolutionized the entire medical profession, and provided a basis for diagnostic radiology. The x-ray showed the internal structures of the human body, without having to resort to surgery. Roentgen’s discovery of x-rays was a discovery that would benefit mankind for years.

In the remainder of my third year I came to further appreciate just how integral radiology is to patient care. Whether it was quickly diagnosing appendicitis in the middle of the night, helping an oncologist determine staging to guide therapy, or draining an abdominal abscess; radiology was often central to determining the management plan.

of an electron within an accuracy range of 3%. In 1913 he came out with a

He also explained how to calculate Avogadro's number and molecule sizes. Einstein believed that the speed of light was absolute and that time and space were relative, which is the opposite of what people believed at the time. Léo Szilard, Einstein’s former pupil, and Einstein both created a different model of refrigerator, called the Einstein refrigerator. Albert Einstein won the Nobel Prize in 1921, because of his explanation of the photoelectric effect.

The X-ray is watershed moment in neurosurgeon because it shows tumors, bone cancers and fractures. Although many doctors use this machine its very important for surgeons since they need to see where they need to diagnose or even start the surgery. This machine was invented on November 8, 1895 by Roentgen but as the machine has been being used over all these years and technology advances he began to realize he can also start to diagnose people with what the X-ray shows such as

He next worked on a project called Wardenclyffe, which was an early radio transmission tower. After much investment, the project was unsuccessful. Eventually, the tower was dismantled and sold for scrap. It was around this time that Marconi was given credit for the invention of radio, up to and including a Nobel Prize. Tesla was deeply resentful, and spent years fighting for his rightful credit.

Before Einstein, Scientists believed that light waves travelled through a medium called ether. Einstein proved that ether was irrelevant and that light doesn’t travel through a medium. Einstein proved this by figuring out that the speed of light was constant, and in order for ether to be the medium light waves travel through, the speed of light would change depending on the observer. This discovery was one piece of the Specific Theory of Relativity.
