Have you ever wondered how Christopher Columbus and Marie Curie died? Well in the two different stories we read‚ the authors go through and talk about each person’s life from when they were younger to when they died. Throughout the both of the stories‚ you can see that Christopher Columbus and Marie were very much the same. But also the two people are very different. Marie and christopher both died of various types of diseases that slowly made them ill and later killed them. Both tried to accomplish

There is a phantom killer lurking in our homes‚ office buildings‚ and schools. We cannot see it‚ taste it‚ or smell it. In fact‚ according to the Environmental Protection Agency (EPA)‚ it is estimated to cause between 15‚000 and 22‚000 lung cancer deaths per year making it the second leading cause of lung cancer deaths following cigarette smoking (EPA). This phantom is the radioactive gas called Radon. Interestingly radon is a form of radiation that is a natural part of our environment. Radiation

transmitting electric arcs between two ends of cathode ray tubes. Some physicists discovered some substances that spontaneously emitted invisible rays regardless of electricity or any other type of energy. An example of these substances are: uranium and radium‚ which are named radioactive materials. X-rays were a portion of the emitted rays that had the ability to penetrate dense objects. Beta rays were labeled as rays that displayed high levels of energy. They had the ability to‚ when covered with a saucer-shaped
