Closing Remarks
Heisenberg was another scientist who had a difficult time trying to get his peers to respect him and listen to his scientific innovations. One of his greatest contributions to physics was the Heisenberg Uncertainty Principle which stated that it is impossible to precisely measure two measurables such as position and speed at the same point in time. This is in contradiction to classical physics because we have always believed that we can measure everything at a given moment, and there are no unanswered questions in physics. Heisenberg's uncertainty principle proves this notion wrong. Throughout this course I have learned about the physics of everyday interaction and now I look at everything from a new perspective.
This week one of our readings was George Bush's State of the Union Address and the other was U.S. Secretary of State Colin Powell's February 5, 2003 address to the U.N. Security Council. In both speeches they talked about Iraq. President Bush's speech was interesting because he talks about everything he has accomplished a few short months after 9/11, and his speech seems uplifting to the common American. He talks about terrorists who we captured, and how the American troops freed innocent Afghans. He also mentions that the government found out that the enemy has diagrams of our nuclear power plants and making chemical bombs. His tone makes it seem that through his leadership we will fight this war on terrorism and with the government's hard work we have arrested tons of terrorists. The world is becoming a better place with the persistent action of the government. He also talks about weapons of mass destruction and his goal is to get rid of them. Bush wants to increase military spending in order to deter Iraqi production of weapons of mass destruction. Bush pledges to win the war, protect the homeland, and revive the economy, but now from a current perspective one can laugh at his pledges. I believe that he has successfully accomplished one of those, which is to protect the homeland. We have been in Iraq for what seems like an eternity and we have not proven anything except that we are destroying their land and destroying many innocent lives. The Iraq situation is almost analogous to the Nuclear Non Proliferation Treaty situation in Europe. In both cases we want to deter nuclear weapons and are trying to find the best ways to defeat the enemy. In the Iraq War we are trying to get other countries to support us and aid us in fighting this war. Similarly, for the Nuclear Non Proliferation Treaty the US wanted to get specific countries on their side to stop the spread of nuclear weapons. It seems that we have always been involved in trying to stop the potential of having a nuclear war. In terms of Colin Powell's address he spoke about Resolution 1441, which was to disarm Iraq of its nuclear weapons. In our efforts to stop the war on terror we have given Iraq multiple opportunities to comply, but nothing has worked. His speech talks about how the US has given Iraq many chances, but they have been reluctant to do anything, thus we must take stern measures. His speech also talks about how we are not only worried about the weapons, but what terrorists can do with these weapons who will use it against innocent people. He denotes a very strong message in his speech; that being the American people and government will not stop until Saddam is stopped and the US can't run the risk of the American people being hurt. Throughout his speech, as well as, throughout Bush's speech his words are strong and puts up a fierce facade for his audience. From the start of the Nuclear Non Proliferation Treaty and continuing to the present time, we have had a strong stance against other countries and nuclear weapons, as we are fearful of the destruction that can be done to our country.
In terms of politics and history, I have learned how various presidents have dealt with international conflict and how different scientists have dealt with oppression and being ousted from their science communities. For not being a science person, I never realized how great a role science plays in the international community, and without one country essentially the entire link is broken. International relations are key in every discipline, not just politics which was always my assumption. Of course political international relations affects history and how things are done, but every country is reliant on each other for information. This class has showed me the extent to which the country is a global community and has opened my eyes up to thinking of science in a whole new way.

The Decisions Leaders Have to Make
There is always a possibility that the other side will attack, and then it comes down to who has the bigger weapons. Leaders have to try and predict what the other side is going to do and sometimes have to make rash decisions. They have to grapple with trying to figure out what is best for the country, and their citizens. Sometimes people forget that weapons have other side effects aside from killing a population; they can also destroy homes and land which make it impossible for a country to rebuild after disaster. Survivability is an important topic that leaders have to consider; is my population going to survive after a nuclear attack? In the Nuclear Age Reader article, it said that when people heard of a possible attack they did not run out and get bottled water and supplies. If this situation occurred today, people would be running to the stores and loading up on supplies. In the case of 9/11, when we had high terrorism warnings, duck tape was flying off the shelves and people were stocking up on bottled water and canned soup. It was comical looking back at this instance, and it depicts how easily society believes authority. The government was making requests to get duck tape and wood, and people didn't question it, but rather ran out and got the supplies. As a citizen, I would feel better if the government funded some of these safety precautions instead of pumping all of the money into the military. In a way, wartime is a huge propaganda stunt for the government because society is so vulnerable and fearful, they will believe anything. People will waste money on superfluous things; no wonder there is always an economic bomb during wartime. In the case of the Cuban Missile Crisis the government made society worried about the effects of an attack and spurred the fallout shelter campaign. If the government was so worried about building shelters, then they should have contributed to the cause and given money to build them instead of putting all of it toward military spending.
The game of war is one of risk and predictions. You have to always be on your toes and guess when and how the enemy is going to strike. Should we do a first strike launch or wait until the enemy does something to us and then retaliate? The problem with first strike initiative is that the second strike could be worse and once you strike there is not going back. Leaders have to always be quick on their feet and try to do what is in the best interest for themselves as well as the country. Once a war starts, it is hard to stop it and one might think the enemy doesn't have the capability to destroy them, when in actuality they do, then what happens? You can't rewind time, and for some of history, including the current war that we are in, I feel that leaders wish they had a remote control so that they could undo their mistakes.

The Pros and Cons of Nuclear Energy
I don't think that Teller was discounting nuclear reactors all together, but he wanted the Advisory Committee on Reactor Safeguards to regulate the reactors. He recognizes the fact that in the past, explosions haven't been very detrimental to society. He stipulates the fact that the one thing that people are most worried about is the possibility of the reactor to explode. Although these fears are eminent, an explosion will only affect the people in the immediate surrounding areas. The thing that he is most worried about is the nuclear poison from the reactors. He acknowledges the fact that although the possibility of an accident is small, we can't be naive, and if an accident were to happen it would be disastrous to the community. Weinberg looks at this same point from a different perspective and believes that although accidents are inevitable, their is a small probability they would happen, and it wouldn't have as great an effect on the community as we think. Unless the community is built right on top of the plant, one doesn't notice the effects until way after the explosion. Teller also realizes that the construction of reactors are inevitable, and so are accidents thus, no legislation will be able to stop accidents or mitigate the effects. Teller has a realistic view to the creation of reactors, although we can't stop them, the government can aid in making them safer. He also notices that they are a good thing for the advancement of science. Lastly, Teller believes that a less expensive source of fissionable materials needs to be found, which Weinberg has the solution to this problem via breeders. Teller states that the lower the cost of atomic weapons, the more we can produce which is advantageous for our military.
Weinberg is an advocate for the breeders because they will produce more energy in an efficient manner both scientifically and economically. The breeder creates more fissile material then it destroys and " a breeder extracts so much more energy from a gram of uranium than does a burner, we can afford to pay very much more for that gram of uranium if we burn it in a breeder than if we burn it in a burner" (Weinberg 9). Inevitably, he is arguing that we should expend all of our resources to build breeders, but with the changing government there is a halt in creating breeders ( ie. Carter's energy policy and the Clinch River Breeder Reactor which will just be an image). Similar to Teller, people are afraid of the nuclear waste, the potential meltdowns and other accidents, and economical aspects of breeders. Weinberg argues that in the long run we will be successful if we use breeders and we shouldn't worry about the effects. He is a strong advocate for breeders. It we put the right people in charge of overseeing breeders and reactors then their should be little to worry about. Society is so afraid of nuclear technology, and what we need is for scientists to precisely depict how nuclear technology can benefit society, so that it will assuage apprehensions against such projects.
The effects of Chernobyl were shocking, and that made people hesitant of bringing nuclear power to the United States. Chernobyl was a freak accident that could happen anywhere, and although we don't want it on our turf, we should not discount the positive effects that nuclear energy has for society. Teller and Weinberg give two different accounts of their views of nuclear energy, as Teller doesn't necessarily not like it, but would feel better if there were safeguards. Whereas, Weinberg is a strong advocate for nuclear energy and believes it has many promising effects. Where do you stand?

Atomic Euphoria
The images from National Geographic depict people with helmets, lab coats, and behind glass so that the radioactive liquids don't touch them. obot hands were used to pour radioactive liquids in order to protect the scientist from exposure. If people know uranium's harmful effects and that it could kill anyone, how did scientists happen to come across this material and decide to use it for bombs? If it is so dangerous how could scientists possibly have done all of the necessary background research in order to find all of its effects. In connection with the reading for this week in Nuclear Choices, it seems that scientists still don't know all of its effects on society. No one imaged the great destruction that uranium could do to society, and not only to a little section of the world, but a bomb dropped would affect everyone in one way or another. Although uranium and other radioactive materials have grave effects on society, it was interesting to see how overtime these materials are constantly being used in order to advance science and medicine. Uranium was used for cancer patients, gamma was used in order to keep foods from perishing, and carbon-14 was used in order to see how photosynthesis works in plants. These elements are often seen as harmful, and indeed they are, but according to these images, we must take risks if we want to advance our knowledge in the science and medical realm.
I feel that one could almost argue that the images in the National Geographic to some extent, as well as, the Plowshare movie were examples of government propaganda. The whole time that I was watching the Plowshare movie, I felt that the government was trying to sell me something and tell me that Plowshare can give economic growth for the community, as well as, can pave the way for nuclear technology and nuclear expansion. The images in National Geographic represent the "good things" that uranium and other radioactive materials can bring to the community and essentially change society's life. The movie stated that Americans shouldn't be afraid of nuclear technology and that through rigorous experimentation and studies they will find a way to control explosions and make them safe. Plowshare can make the technology that the United States needs in order to move toward their nuclear goal. Also, Plowshare made a convincing argument that their goal will not be costly; by using the different graphs and comparing their methods to conventional methods and costs it seemed promising to the average American. Although the Plowshare movie looked like the United States was on their way to finding prosperous nuclear technology, the American public was not persuaded by the idea. Although through pictures and statistics they were showed that it can benefit them, is safe, and is not a waste of money, the public was still skeptical about the government's motivations, as well as, fearful for their own lives.
During the era of nuclear power magazines and media attempted to depict the benefits of nuclear power to society. They used persuasive pictures and convincing arguments to tell people that nuclear power would not only advance our nation but would aid the United States scientifically, medically, and technologically.
Nuclear Destruction and its Effects on Earth
Another hazard from the destruction of bombs is the overpressure that could essentially crush objects. The bomb's energy is responsible for most of the physical destruction. Although humans are immune to overpressure, the objects that are harmed by it can kill people. I don't understand how people are immune to this overpressure if it is so great, but that is another subject of physics. Also, the fires that are started by the thermal flash, as mentioned earlier, not only have effects on the ground but also in the atmosphere. The fire consumes remaining oxygen which suffocates the remaining survivors of the blast (321). Clearly, the bombs suit the purpose they are intended for, major destruction and killing. The explosions from the bombs can kill people either thousands of miles away or right in the vicinity of the bomb.
An interesting concept is that the United States is cognizant about the destruction of an all out nuclear war, but when it comes down to saving society from the bomb's after effects, they would not be prepared to save people's lives. Thermal flash burns could affect people hundreds of miles away and the burns require special treatment. That being said, the United States does not have adequate facilities to treat all of the people that would be affected by the burns or any other injuries. If the United States was involved in a full out war, people would be affected by it no matter if they were 10 miles or across the country from the bomb. Atomic radiation can cause lowered disease resistance which can lead to death, and if bombs blow up medical facilities there aren't enough adequate places to get care for all of the people who are harmed (332). Besides a health crisis, transportation would be greatly affected because it would be blocked by debris and potentially blown up. In addition, neighborhoods and neighboring cities would be in shambles. Therefore, there would be nowhere or noone to ask for aid. Lastly, a large scale nuclear war would elicit dust and chemicals into the atmosphere. The excess chemicals would seep into the ozone layer and burn through it, thus causing ultra-violet radiation to reach Earth. The increase in UV would affect humans, plants, and animals. Atomic bombs not only affect the enemy directly but the areas around it, as well as, drastically change the environment one lives in.
It is no surprise that nuclear weapons caused a huge raucous among the public. The morality and health effects of a nuclear attack need to be questioned and the reasoning behind using a destructive weapon needs to be reevaluated. In the end, it seems like the atomic bomb could so more harm then good to a society.

Morality and Responsibility of the Atomic Bomb
Ethics plays a large part in the decision of dropping the bomb. In order to advance the U.S. and minimize Russian influence do we drop the bomb and risk innocent lives or are there other ways to deter Russian influence? Oppenheimer said that " the more horrible and inhumane the weapon, the stronger the case would be for its postwar control". Therefore, dropping the bomb looked like it would help the U.S. obtain its goal. It is hard when different ideologies are working on a common goal. Politicians, scientists, and historians, all have differing opinion on if the bomb should have been dropped. Politicians would want to advance the status of the country and make it powerful, as well as, increase international relations. While scientists would look at the bomb as scientific advancement and it opens up another window in the science realm that can be further explored. Historians could look at it from the perspective of how the bomb impacted events that spurred from the incident. Would certain wars have spurred if the bomb wasn't dropped or would our relations be any different between countries if we did not have the atomic bomb?
The notion of morals always comes into question in science and politics. From a politician's viewpoint, we wanted our country to be in a powerful position, so dropping the bomb would put the U.S. at the paramount of the international realm. Morally, it can be argued, it was right to drop the bomb because we were fearful Germany was working on an atomic bomb and we were scared of the Soviet power. We didn't want Germany to beat us or the Soviet to take over the world. It was in our best interest, especially later in life to drop the bomb. Looking at the atomic bomb from a scientifically moral standpoint is a little harder. Scientists often know better then anyone else the impact of such an explosion and how the after effects are going to hamper society. It is their duty to warn others who are less knowledgeable about the atomic bomb in this respect, of the consequences. In a sense, they were morally obligated to fully explain how the explosions would affect society. One must also think about the psychological factor that comes with the bomb. Killing civilians has the greatest psychological affect on anyone no matter your role in the act.
The dichotomy between the scientist and the politician is one that we grapple with. The Interim Committee was formed to decide what happens with the bomb and they had a Scientific Advisory Panel which aided them in their decision. One argument is that the scientist should be responsible because they built the bomb. Contrarily, the scientist believes that he is not held responsible because he did not launch the bomb; that is the responsibility of the politician. He was employed to build the bomb, but he has not responsibility with what happens to it. The issue between responsibility makes people wonder why even build something so destructive as a bomb is no one wants to take credit for it. It is common knowledge that a bomb causes ruin and chaos so inevitably someone has take responsibility.
The dropping of the atomic bomb on Hiroshima and Nagasaki is a debate that will be left unanswered. President Truman's initial reaction was that it was a good idea because the war was going to be over. The public became uneasy of the fact that nuclear bombs existed because they feared their long term impact. The dropping of the atomic bomb was a pivotal point in history and no matter how long people scrutinize over it, there will always be an argument about it is was the appropriate thing to do.

Bombs and Black Holes
/Events/A136FC42-F9B5-46A5-A0CB-F0007B262E14_files/Black-hole.jpg)
The notion of the atomic bomb and Germany's ability to create the bomb is another issue that leaves people frightened and skeptical. Historians pondered if Germans had the ability and resources to make the atomic bomb, and the answer according to Professor Walker was yes. Although, the German war economy had less money then the successful American creators of the Manhattan Project, and Hitler's plan to oust non-Aryan scientists succeeded, they still had creative and intelligent physicists and chemists and an abundance of resources. Hitler's fault, some argue, was detrimental and a determining factor to German's success or failure of creating an atomic bomb.
In the science realm, the discovery of nuclear fission opens up new doors. Once they learned about nuclear fission, they realized that there were areas for exploration. Due to the state that Germany was in at the time, people might see the development of the nuclear bomb and their ability to use atomic fission as dangerous and a threat to the world. Scientists were only trying to contribute to German's technological and military advancement, expand their knowledge and use their creativity. Although, scientists were going to use nuclear weapons for the future, it was worth the time and effort to create them. It is somewhat surprising that German scientists and officials disagreed with the idea of expending time and effort into nuclear weapons. The German uranium project had little effect on the war economy and the scientists had difficulty in getting things that they needed. This was due to lack of priority, and it is surprising that such an extreme and important project would be demoted. Looking back at the situation, scientists probably wish they put more time and effort into the research, since the United States and Soviet Union succeeded in developing the weapon.
Ultimately, I believe the German scientists gave up without a fight. The funding, resources, and intellect was there to build successful nuclear weapons but the motivation was lost. Not until the bomb was dropped on Hiroshima, did the scientists realize their loss and they became disturbed. Hahn was in denial of the situation and believed that his work didn't have to do with weapons. The scientists didn't want to believe the disastrous impact of nuclear fission. The discovery of nuclear fission essentially took a path that was not foreseen, and instead of aiding Germany it only created more controversy.

Classifiable or Quantifiable
In the 1930's, Stark and Lenard instituted this idea of classifying science as"Aryan Physics" or "Jewish Physics". Aryan Physics was non Jewish, perfect and pure science. Aryan Physics did not agree with relativity and quantum mechanics because it left unanswered questions. Once again, Einstein is belittled and hated among the German scientific community for his work. Einstein also did not agree with the National Socialist party, as he was part of the anti-Fascist movement. This discord between his political views and the National Socialist party, as well as, his scientific views gave Stark a reason to hate Einstein.
As Hitler slowly took power, the German citizens were classified as either Aryans or non-Aryans. These classifications allowed people to start to reject non-Aryans in the educational and scientific realms. There was a law against the overcrowding of German schools and universities, which essentially was an excuse for Germans to not accept Jews into their schools. The creation of all these bogus laws, justified the Germans' claims, and to the average citizen made the Germans' actions appear legal. I don't understand how a government can legally classify a person and how the Nazis got away with their actions. A non-Aryan was defined as someone who had one practicing Jewish grandparent. This definition is quite vague, and not until the 1935 Nuremberg laws did Germany have a concrete definition. Under these laws, a non-Aryan was a person who had three grandparents who were registered as practicing Jews. The reason behind having such an extensive family guideline was because many grandparents were dead or wouldn't change their faith, thus people couldn't easily change their faith. It is easier for a person to say that they are Jewish if they have extensive family lineage that demonstrates Jewish practices, then going by one relative who could have converted. Once again, this idea of the government not being able to easily classify things upset the Nazis. It was easier for the government to take control over scientists' practices, schools etc. if they have a "black and white" law instead of a "gray" one. Classification, in this instance, put the government's worries at ease. It allowed for the easy extermination of Jews years later, as well as, the ability of the Nazi's to take over science, education, and ultimately the German government.
Throughout our readings we have seen many concepts classified and the scientists, government officials, etc. use these classifications as justification for their actions and beliefs. Whether we are classifying science as "Aryan", "quantifiable", or "pragmatic", science should be universal and respected, and these classifications should not have any effect on how people view the concepts. Similarly, if we classify people as "Nazi", "Jewish" "White Jews" etc., we are saying that we must section people off and we can not see "eye to eye". By classifying something it give a sense of status and states that one group is not related to another. Society might be able to understand each other and the inner workings of the world, by erasing all of these classifications and labels and just looking at a concept or a person for what it is worth.

Finding the Right Formula for International Relations
When I first entered this class I didn't know what to expect. I had no idea how physics and politics related to each other. Science to me is just a bunch of numbers and formulas, but after the first few readings and classes I have realized that physics plays a huge role in my everyday life. My everyday actions are affected one way or another by science and I hope that by taking this class I will gain a better understanding of the physical world around me. I am very interested in politics, so it will be interesting to see how science can also be political, and how people in history have used science to advance themselves in the international realm.
