Economics Module 3 - Assignment Example (10 pts.) Watch  at least one of the following entertaining videos:   (i)  LearnLiberty.orgs The Broken Window Fallacy  (3.09); and (ii)  Stossel Macro Video 04 - Government spending, jobs, and unemployment  (2.40) Listen  to or read at least one of the following pieces: (i)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  What is Seen and What Is Not Seen  by Frederic Bastiat. Or, listen-on-the-go to the  Audio   (8.11); and (ii)Creating Jobs vs. Creating Wealth  by Dwight Lee (Audio, 8.58 minutes).    Directions:   Use your knowledge of the â€Å"Broken Window Fallacy† to evaluate each of the following claims.   These statements are used frequently by proponents to argue that government spending can help pull an economy out of a recession.  What does economic analysis indicate with regard to this argument? (Hint:   Write the â€Å"seen† and the â€Å"not seen† effect of each one of these proposals.) 2.1  Ã‚  Ã‚  Ã¢â‚¬Å"I propose that we hire all of the unemployed people as government workers and pay half of them to dig holes and the other half to fill them back up.   This way everyone who wants a job can have one!† This is a true policy that was implemented by the government to basically find a reason to spend. As of now, the focal point is in spending when the government must enact programs to stimulate growth. FDR has similar initiatives during the Great Depression as he forced the government to spend in public infrastructure even when it was necessary. This policy created jobs and reached its objectives of keeping unemployment rates low. 2.2  Ã‚  Ã‚  Ã¢â‚¬Å"The unemployment rate is high and, therefore, it is time to stimulate the economy!   I propose that we use tax dollars to pay car dealers to destroy older used cars by smashing them and sending them to the dump.   This will cause people to buy new cars which will increase economic activity and put us on the path to

The use of the x ray machine in the medical field. And how it was invented and how far it has come (technology wise) and also it - Research Paper Example The discovery was actually accidental. The scientist found that invisible rays were emitted from a cathode ray tube and that these could penetrate wood and also paper. These rays were able to create a glow on a screen that was several years yards away. The glow was fluorescent. The screen that was observed was barium platinocyanide screen (Assmus, 10). The tube generating X-rays, the cathode rays was Crookes tube (Assmus, 10). The scientist made use of these properties to study the structure of bone of human hand. Several years after discovery of these rays, actual X-ray machines were invented. In 1900, it was discovered that radium rays are actually dangerous to skin. Radiology began to emerge as one of the medical specialities in 1900. Skill, the technical know-how and interpretation of image improved significantly (Linton, 27) X-rays are basically electromagnetic waves and their behavior is similar to light rays (Dendy, 48). However, their wavelengths are short. One useful propert y of the X-rays is, when the rays are directed towards a target that is of low density, they pass through the target uninterrupted. In case the target is of high density, like that of parts of human beings, the X-rays either get absorbed or are reflected. This occurs because of very less space between adjacent atoms in high density targets, which do not allow short waves to pass through. When the X-rays pass through completely through the target like in case of flesh, dark areas are seen on the screen. When they are blocked by high density targets like bones, they appear as light areas (Assmus, 14). It was Roentgen who discovered that X-rays basically originate from the tube at a point where the cathode rays strike the glass and then disseminate (Assmus, 14). He found that the origin point of X-rays moves as the rays coming from cathode are moved by a magnetic field. The X-rays however, are insensitive to magnet. Based on these findings, Roentgen concluded that X-rays are distinct f rom the rays emerging from the cathode, the cathode rays (Assmus, 14). "Roentgen justified calling the new phenomena rays because of the shadowy pictures they produce: bones in a hand, a wire wrapped around a bobbin, weights in a box, a compass card and needle hidden away in a metal case, the inhomogeneity of a metal" (Assmus, 14). Two years after Roentgen's discovery, which was basically radiation secondary to artificial ionization, a French scientist by name Henri Becquerel, discovered natural ionizing radiation from certain types of rocks. The radiation rays were similar to X-rays by Roentgen. The rocks were later refined by his colleagues Marie Curie and Pierre Curie to deliver radioactive substances radium, uranium and polonium. Radium is now being used to treat cancers (Linton, 26). Roentgen won Nobel Prize for his discovery in 1901. That was the first Nobel proze in Physics ever (Linton, 28). William Coolidge from General Electric Laboratories developed cathode X-ray tube tha t was an improved version and was hot. The X-ray machine was shielded suitably to prevent scattering of radiation that harmed the technicians. Thus, X-rays emerged from the tubes, known as Coolidge's tubes, through a lead shielded aperture. This method of exposure to X-rays allowed patients to be placed within a beam of X-rays and at the same time allowed others to be kept away from the beam. A further advancement in this method of X-ray exposure
