Analysis paper Essay Example | Topics and Well Written Essays - 500 words - 1

Analysis paper - Essay Example that is taken care of or is valued even if taking care of it costs the caretaker important things in his/her life; in this case, the relationship between the American and the girl. This is evident from the confession of the American to the girl he has made in this sentence, â€Å"That’s the only thing that bothers us. It’s the only thing that’s made us unhappy† (Hemingway). It is apparent from the dialogue between the two that while the American is not directly telling the girl to undergo abortion, he is indirectly pushing her into this act by constantly suggesting that a lot of people go through the operation and it does not cause any harm. On the other hand, the girl seems to be reluctant to contemplate the operation. This is suggestive of a liking for the unborn baby by the girl and a dislike by the American. Similarly, while the girl can see the mountains as white elephants and appreciate their beauty, the American does not seem to relate to the white mountains in any way as he says, â€Å"I’ve never seen one† (Hemingway). The girl says to the American, â€Å"No, you wouldn’t have† (Hemingway). This attitude is typical of girls. When a man does not seem to understand or approve of something that is of huge significance to women, women say that the men cannot understand because only a woman can understand the importance of that thing. For example, it takes becoming a mother to understand the warmth and passion with which a mother loves her child; a man can never understand this love because he can never become a mother. In response to this, the American says, â€Å"I might have†¦Just because you say I wouldn’t have doesn’t prove anything† (Hemingway). Now this is an attitude typical of men. They are too egoistic to give up even if they actually don’t know about something. The girl has a number of reasons to want the baby just like the American has them to not want the baby. The American does not want the child probably because it takes a lot of

Discovery of electrons(J,J Thomson) Essay Example | Topics and Well Written Essays - 750 words

Discovery of electrons(J,J Thomson) - Essay Example Cathode rays were an enigma during the late 1800s. Many Europeans thought that the rays emitted at the cathode in the discharge tube were an ethereal disturbance, like light. Crookes proposed in 1879, that the cathode rays were radiant matter or negatively charged particles that were attracted to the anode and repelled from the cathode (Cambridge Physics, 2015). In Germany, Hertz conducted an experiment where he observed that the rays discharged could pass through very thin gold sheets. He also conducted another experiment to find out the impact of electric fields on the rays and wrongly concluded that the rays were not deflected by the electric fields. In 1897, J.J Thomson repeated Hertz’s experiment (Cambridge Physics, 2015). The difference between J.J Thomson’s experiment and Hertz’s experiment was that J.J Thomson conducted his experiment in a vacuum tube. Hertz had too much gas in his discharge tube and the gas had become ionized by the electric field. The positive ions were attracted to the negative plate and the negative ions were attracted to the positive plate. This reduced the net charge on the plates and the strength of the field was not enough to deflect the cathode rays. J.J Thomson repeated the experiment and when he passed the cathode rays through the electric field in a vacuum, deflection occurred. The fact that the cathode rays moved towards the positively charged plate allowed him to conclude that the rays must be negatively charged. After this, J.J Thomson used two coils of wire known as the Helmholtz pair to produce a uniform magnetic field. Any beam of charged particles when passed through the magnetic field produced by the Helmholtz pair will be bent at 90 degree angle to the field into a complete circle Using this concept, J.J Thomson positioned the coils to cause a deflection in the opposite direction to that produced by the electric field. To balance the forces
