Science is intuitive. The tallest hill can be the shortest mountain. It is through our intuition that we come to know that the big ones are mountains and the little ones are hills. In some ways, the same is true for science. Science encompasses everything ranging from chemistry to archaeology, microbiology to astronomy. There are so many different aspects to science that it is hard to boil down to one concrete and concise definition. Science is involved with the study of the natural world. This however; does not mean that science denies the existence of the supernatural. Science does acknowledge supernatural things as long as there are “scientific endeavours” supporting it. A scientific endeavour is simply an experimental process or investigation

New development leads to changes in experimental methods. J.J. Thomson contradicted Dalton’s atomic theory by using a cathode ray tube. Thomson was born in 1856 and the cathode ray tube was invented in 1897; almost the same time during his years. He took a positive magnetic source near the rays and found the rays deflect to the positive and repel when a negative magnetic source was near it. From the classical physics of Newtonian physics, he figured that opposites attract and likes repel. Since the cathode rays followed the similar approach, hence they were determined to be negatively charged or electrons. Therefore, using previously held theories, further discoveries can be made and new theories can supersede …show more content…
It is a vacuumed glass tube. When two metal plates are connected to a high voltage source, the negatively charged plate or the cathode emits an invisible ray which passes through a hole in the middle of a metal plate while the rays are drawn to the positively charged or anode. The cathode and the anode are located at the ends of the cathode tube. The anode is a specially coated flat surface. As the rays strike this surface, they produce a strong fluorescence or bright light. Back in Asia, my family members own a cathode ray tube (CRT) TV. They find them the least expensive and extremely reliable. I had one at my house and I felt that the TV worked pretty well on day-to-day basis. It was extremely responsive. I particularly loved the colour contrast. When I was young and I watched cartoons, colour mattered to me the most. The only thing which bothered me most was when there were thin distorted lines on the screen and the whole geometric shape got distorted. This was particularly when I tried to connect an external hard drive to my TV. But, undoubtedly, the most annoying problem was the size of my TV. It is so large, heavy and
