The English word “person” has a long and convoluted history. Though the word itself likely derives from the Latin, persona, referring to the masks worn in theatre, its meaning has evolved over time. One of the biggest conceptual overhauls came in the 4th century AD during a church council that was held to investigate the concept…
Last week, 20 months of negotiations between 7 different countries came to fruition. The Joint Comprehensive Plan of Action (JCPOA) was signed by the US, China, Russia, UK, France, Germany, and Iran. The Iran Nuclear Deal, as it has been popularized, is a groundbreaking event in diplomacy with one of the most volatile nations in an area of the world that is historically unstable. The JCPOA has many confused about not only the details, but also the general concepts of the plan. I will try to keep jargon low and explained, so that this post will, hopefully, dispel some of the confusion.
Here are some terms for those unfamiliar with the uranium enrichment process:
Isotope – A variant of an element that has a particular mass (number of neutrons + protons). Heavier and odd numbered isotopes tend to be less stable.
Uranium 235 – The uranium isotope that is easily split (fissile) to produce energy. Uranium ore contains 0.7% U-235.
Uranium 238 – A stable uranium isotope that is not fissile and is not used for energy. Uranium ore contains 99.3% U-238.
Plutonium 239 – A fissile byproduct of nuclear reactors
Heavy Water – Water molecules that contain Deuterium, which is a stable isotope of Hydrogen containing an extra neutron, giving it greater mass.
Low Enriched Uranium – Uranium with less than 20% concentration of U-235.
Highly enriched Uranium – Uranium with greater than 20% concentration of U-235.
Uranium Hexafluoride (UF6) – Uranium that is bound to 6 fluorides. This form of Uranium is necessary for enrichment with the gas centrifuges.
Uranium Dioxide – Uranium bonded with two Oxygens. This form of Uranium is packed into fuel rods and used as fuel for nuclear reactors.
Beta decay – A neutron can be seen as a proton and an electron combined. During beta decay, the neutron emits the electron (referred to as a beta particle, hence beta decay), which effectively turns the neutron into a proton, thus changing the element into a new element (one that is immediately after it on the periodic table). For example, if Carbon (#6 on the table) beta decayed, it would become Nitrogen (#7). This occurs in the atmosphere as a part of the Carbon 14 cycle.
The most common thing I’ve heard regarding the deal is that people are uncomfortable with the Iran having nuclear power “now.” This, I assume, stems from a misunderstanding of what the deal was designed to do. The JCPOA doesn’t give Iran anything; Iran has had a nuclear program for years, and has been enriching uranium to amounts that are pushing the boundaries of normal energy usage. The JCPOA will require Iran to do a few things to reduce the chances of them creating a nuclear weapon, which I will explain one by one:
- Reduce their current uranium stockpile by about 96%
- No Uranium enrichment beyond 3.67% for 15 years
- Use only ~ 5000 of the lowest efficiency centrifuges (out of about 19,000) for the next 10 years.
- Redesign the Arak heavy water reactor
- No building heavy water reactors or stockpiling of heavy water for 15 years
- Allow comprehensive and unprecedented international inspections of facilities by the International Atomic Energy Agency (IAEA)
- Convert the underground Fordow nuclear facility into a nuclear, physics, and technology center where international scientists will also be stationed
- Ship spent fuel to other countries
- In return for the above tenets being met, economically crippling sanctions by the UN, EU, US, and possibly other individual countries, will be lifted.
Let’s start with the first – Stockpile reduction:
This one seems to be an obvious win. Iran has around 20,000 lbs of low enriched uranium (~5% U-235) stockpiled. With this provision in place, they would be reduced to 660 lbs of low enriched uranium on hand. The reduction would be done by either shipping the uranium out of the country or diluting it. Iran also held about 460 lbs of 20% enriched Uranium. Since January, 238.5 lbs of this has been diluted to less than 5% enrichment. A little over a pound was retained by the IAEA for reference, a fraction of a pound was taken by the IAEA for sampling, and the remaining 220 lbs is in the process of being converted into Uranium dioxide, which is used for fuel rods. Research reactors, like the one what Tehran, run on fuel rods with 20% enriched uranium. Iran’s Fuel Plate Fabrication Plant has no process line by which the oxide can be converted back to UF6 to be further enriched.
3.67% enrichment cap:
The percentage of U-235 (enrichment level) in your Uranium says a lot about your intentions. Uranium that is enriched to 3-5% is used in regular nuclear reactors for energy production. Uranium at 20% enrichment is often used for research and production of medical isotopes. Iran claims that it has enriched uranium to 20% in order to supply the Tehran reactor for production of medical isotopes. This is actually not an unreasonable claim. The last shipment of 20% uranium into the country was in 1992 by Argentina. This would last about 20 years at the most, so Iran does need 20% enriched uranium to continue production of medical isotopes that are used in everything from radiation treatment to medical imaging.
Cut in centrifuge use:
The details on the types of centrifuges and their usage are some of the more complex parts of the JCPOA. However, the main points are pretty straightforward. The gas centrifuges used to enrich uranium are a little different than the typical scientific centrifuge. These centrifuges use diffusion of gaseous UF6 (see terms above) to separate the lighter U-235 from the heavier U-238. This process isn’t too efficient, particularly with the old equipment that Iran would be required to use. Successful enrichment, even to 3.67%, requires an assembly line of centrifuges, where the products of one centrifuge becomes the reactants of another. Keep in mind that uranium ore contains less than 1% U-235. Under the JCPOA, Iran would only be allowed to use about 6000 of their almost 20,000 centrifuges. Is this enough to make a bomb? Sure. I suppose 600 would be enough. However, the point is to make is difficult – and overt – for Iran to enrich uranium to weapons grade.
Redesigning the Arak Heavy Water Reactor:
The details on this are vague as of now. Supposedly, the reactor core will be filled with concrete and then redesigned according to UN regulations with the help of international scientists. Claims are that this will help reduce the potential of Plutonium being produced in high quantities. I’m not entirely sure what kind of redesign would significantly reduce this potential, other than the fact that heavy water reactors do not require enriched uranium. Because the water is “heavy,” the reaction process is much more efficient. Heavy water already has extra neutrons, and so it is less likely to absorb the neutrons that are used to split U-235. Thus, your concentration of U-235 doesn’t need to be as high to achieve efficiency. A consequence of low-concentration U-235 is over 99% concentration of U-238. U-238 doesn’t split easily, so it tends to absorb neutrons, which will be in even higher abundance if the water isn’t absorbing them. When U-238 absorbs a neutron, it becomes U-239, which is unstable and beta decays (see terms for info) into Neptunium 239. Neptunium 239 is also unstable, so it beta decays into Plutonium 239, which can be used as fuel in the same way as U-235 if left in the fuel rod. However, Plutonium 239 can be removed as it is created and replaced with more Uranium. This is how Weapons grade Plutonium is stockpiled. Fortunately, this shouldn’t be a difficult thing for IAEA to monitor, as the inspectors will know how much should be present. Much of the success of this deal will fall on how well the inspectors do their jobs.
No stockpiling heavy water or building heavy water reactors for 15 years:
This follows the previous point. Not only will Arak be redesigned, but Iran will not be allowed to build or collect material (heavy water) to build a heavy water reactor for 15 years.
This part of the deal is a bit vague as well. However, it is one of the most important aspects. Iran is essentially on probation right now, and the IAEA is its probation officer. If Iran does anything wrong, sanctions, the levying of which are the main reason Iran is trying to make a deal, will immediately go into effect. It would be counterintuitive for them to break the rules overtly, and should be relatively easy to catch if they try to do so covertly. IAEA inspectors will have the ability to inspect not only current reactors and research (not to mention the monitoring or uranium mining and import), but will also be able to inspect “suspicious” areas. There is an appeals committee, and it could take up to a maximum of 4 weeks if Iran claims the inspection unnecessary. However, let’s be real. The US and the rest of the world’s intelligence will be all over any suspicions of the IAEA inspectors. If it’s happening, especially on any scale that could be dangerous, we will find out. The last thing Iran wants is to be resanctioned and show that it cannot be trusted under any circumstances. Even a bad kid does what’s in his or her best interest.
Converting Fordow into a research center:
Fordow is a heavily fortified, underground nuclear reactor. Under the JCPOA, Iran will not enrich any Uranium at Fordow, will convert it to a research center, and will allow international scientists to be stationed there. So, not only will IAEA have inspection capabilities, but the world will have scientific eyes inside of this facility, further reducing any chances of covert, illegitimate activity.
Shipping off spent fuel:
Spent fuel rods are where you get Plutonium 239, as described previously. Under the JCPOA, Iran will ship spent fuel rods out of the country for the lifetime of the Arak reactor, and will not build a reprocessing facility (necessary to separate out plutonium) for 15 years.
Sanctions will be lifted:
Economic sanctions from the US, EU, and UN, as well as other independent countries, has crippled Iran’s economy. These sanctions include heavily restricted imports and exports on many things, including oil, which is one of Iran’s biggest exports. Additionally, Iran has over $100 billion in frozen assets overseas, and was banned from participating in the international banking system. The economic sanctions crippled Iran for many years, deteriorating the quality of life for citizens as collateral damage. The sanctions will be lifted as Iran continues to show cooperation, allowing Iran to prove to the rest of the world that is can be a legitimate part of world trade.
Iran has been in “prison” the last decade or so. They have been showing good behavior through diluting uranium stockpiles even before last weeks agreement was reached. They are now essentially on probation for 15 years. This can be analogous to a recently released prisoner. You don’t just set them free; they do their time and then you assign them a probation officer – in this case it’s the IAEA. If the person shows good behavior and a willingness to be a contributing member of society, they will be allowed more freedom. This is where Iran is at with the JCPOA. This is why it’s a 15 year deal. Iran has 15 years to prove to the world that they can be a participating country in global interactions. The world will have 15 years to learn about Iran’s capabilities and prepare in the event that they break their probation. But, just as a prisoner wants nothing more than to avoid going back to prison, Iran wants nothing more than to avoid sanctions. This deal gives us a chance to form a somewhat diplomatic relationship with a country that, in the past, has been difficult to negotiate with. ISIS is also one of Iran’s biggest enemies, and this diplomatic relationship might help curtail them, but that is a topic for another post. Will this fix all the problems in the Middle East? No. Is Iran our ally now? Absolutely not. Ultimately, this deal lowers the chance of Iran creating a nuclear bomb, gives them a chance to demonstrate their ability to cooperate and participate in global affairs, and is a step closer to stabilizing the Middle East.

Cultural appropriation is a tricky topic to unpack and explain in a manner that keeps the attention of those who believe it to be “PC crap,” but also doesn’t dampen the significance of the issue. But we should try anyway.
I’ve no doubt played a role in cultural appropriation throughout my life, with no bad intentions or awareness that I was doing anything harmful. Growing up in okla humma, Choctaw for “Red People,” I was surrounded by Native American culture. Half of the cities I can name in Oklahoma derive from a Native American word or phrase in the language of one of the 67 tribes represented in the state. You can buy dream catchers and arrowheads at gas stations along the interstate, and Oklahoma museums have some of the largest Native American collections in the world. The designation of Oklahoma as Indian Territory in the 19th century laid the foundation for the incredibly complex and muddled mixing of unique cultures that white people typically lump into “Native American” culture. This amalgamated meta-culture, if you will, has been commodified into a staple of Oklahoma tourist attractions and local affairs. To those born here, the combined Native American culture is a frequent part of every day life, even though many don’t understand the significance of the cultural artifacts in their original context.
Carl Sagan once stated, “… the consequences of scientific illiteracy are far more dangerous in our time than in any time that has come before.” This statement becomes truer every day, as scientific and technological innovations are occurring at an ever-increasing rate. Studies suggest that less than 30% of Americans are “scientifically literate,” meaning that over 70% of Americans would have trouble reading – and understanding – the science section of the New York Times. So, why is this important? After all, everyone has their strengths and weaknesses.
The problem with this view is that science is a driving force behind our sociocultural evolution. New ideas and new inventions are constantly redefining how we live our lives. As time goes on, science and technology will define most of life as we live it. Already, this is true. 100 years ago, people often lived day by day without electricity. Today, the most frightening thing most people could imagine would be a total loss of electricity. Imagine all of the things that simply wouldn’t work without it: phones, televisions, the Internet, lighting, heat and A/C, automobiles, and many parts of the manufacturing process for everyday items. We have built a society in the United States that is almost entirely dependent upon electricity. Personally, It’s difficult for me to imagine a world without electricity because everything I know is based on upon it. Life has become relentlessly complex and multifaceted. Most people have no idea how the world around them – that is, this semi-artificial world, or anthropogenic matrix – functions.
As time goes on, our day-to-day lives will become less and less “natural” and more and more artificial. This is not inherently bad. However, it does raise the standards for what we must understand about how the world, especially our anthropogenic matrix, works. Failing to keep a basic understanding of science and technology is destined to segregate the population, facilitating the rise of an “elite” few, resembling more of an oligarchy than a representative democracy. I’m not much of a conspiracy theorist, and I don’t mean to imply that a “New World Order” is going to secretly control our lives. I do, however, think that if nothing is done about our general ignorance of science, we will slip away from the democracy that we claim to love so dearly. How? How can ignorance of science and technology lead to the failure of democracy? After all, you can vote regardless of your scientific literacy. While it’s true that you can vote while being largely ignorant of how the world works, this is part of the problem. To be clear, I do not think that there should be any kind of scientific literacy test in order to vote. This would only serve as fuel for the ever-broadening gap between those who understand science and those who don’t. In a democracy, everyone should be able to vote. However, given the state of knowledge that we currently have and the increasingly complex world in which we find ourselves, uneducated voting has disastrous consequences.
A Little Politics
Politics is, in its most basic form, the practice of influencing a population. This is done by verbally persuading people to get behind an action that will be set in motion order to guide the population down a particular path of life. The United States is a representative democracy, which means officials are elected by the public to govern the public. The United States is not a simple representative democracy; many modifications are set in order to give the minority a voice. However, in light of these modifications, “majority rules” is still the rule of thumb. On its surface, a “majority rules” system seems ideal. Going with what most people want or believe is the best thing to do seems like a solid idea. I agree that this is typically a good philosophy – that is, as long as those voting are educated on the matter at hand.
The Modern Intersection of Science and Government
The base of everything in our lives is built from science; it holds together our infrastructure. When a politician makes a motion to change or regulate something, he or she is making a change that affects our anthropogenic matrix, and, consequently, the natural world in which our matrix operates through such acts as deforestation, ozone depletion, species extinction, etc. If a constituent does not have a basic understanding of how the world works, then how can that individual make a good decision with regards to electing a public official who will pass laws that affect the world? Moreover, ignorance of science and technology (not to mention poor reasoning and logical evaluation skills that tend to accompany science education) leads to a vote based largely on emotion and superficial similarity. If you know very little about a subject, you cannot make an educated decision regarding that subject. If not based on an educated understanding, something else must be the base upon which you make decisions. The next best choice would be decisions based on reason and logic. Unfortunately, a fostering of critical thinking is also aloof in many educational settings. Science acts as a major source of training by which people learn to reason and form logical conclusions. In turn, many – though not all – who base their decisions on logical reasoning are in the same group of people who base their decisions on knowledge of science.
If you don’t use a knowledge of science to aid in political decision-making, it’s likely that you are more swayed by charisma and emotional triggers. Those candidates who are more like you, or at least are ostensibly like you, are more likely to sway your opinion. After all, that’s what politics is all about – persuading people. If most of your constituents are not scientifically literate, then you as a politician will be less likely to use science as a persuasion tactic and more likely to use charisma and emotionally charged wording that resonates with many of your constituents. Though not a valiant method of persuasion, it is a smart one. Unfortunately, this only perpetuates the current epidemic of scientific illiteracy.
Why Public Knowledge of Science Matters
One major problem with scientific illiteracy is that politicians can make a poor decision, intentionally or unintentionally, with no one to call them out. Regulations or the lack thereof concerning issues such as climate change, medical research, and irresponsible use of resources must be made based on the science that is used to study and understand these matters. If a politician uses a non-scientific basis for creating laws (a basis fueled by a constituency who is scientifically illiterate and, perhaps, an ulterior motive such as monetary stock in the decision), then consequences are sure to ensue. The effects can be immediate, such as lack of funding for education or medical research, or delayed, as with the consequences surrounding anthropogenic climate change.
Politics aside, understanding science and technology is imperative to functioning in our ever increasingly technological world. 100,000 years ago, one had to be a skillful hunter or gatherer; 10,000 years ago, one needed to be adept in agriculture; today, we must stay informed on, at the very least, the basics of science. Expertise is not required for social and political progress, but awareness is essential.
