What is Entropy

What is Entropy?

When an ice cube is left outside, it eventually melts into a puddle. This is an example of the second law of thermodynamics, entropy. Entropy is a measure of spontaneous disorder or randomness in a closed system and the energy, or heat, flows from an area of high temperature to an area of low temperature. In the case of the ice cube, the heat from the outside went into the ice cube, which had a lower temperature, therefore exciting the molecules in the ice cube and melting it. The ice cube went from an orderly cubic state to a disordered puddle.

Additionally, entropy is either constant or increased in the universe. The way things stay organised is because energy is put to keep it that way. For instance, the ice cube stayed in its cubic shape because energy from the fridge made the surrounding cold, therefore freezing it into a cube. When it melted, as said early, entropy happened where it went from a cube to a puddle. The energy stored to keep that cube shape melted and was released to the universe, thus making the entropy of the universe positive.

Psychopaths in Society

BLOG 9: We are afraid of psychopaths because they have no qualms about hurting other people. Discuss

Psychopaths are people with an antisocial personality disorder that lack the ability to feel remorse and sympathy. They are egocentric, charmers and do not have meaningful personal relationships with others. Since psychopaths cannot sympathize and feel for other human beings, they lack one of the basic human emotions which cause people to fear psychopaths.

The main reason that people do not commit crimes is because they understand how the person receiving the crime would feel. However, if a person does not feel in the first place, the crime, in their mind, would be considered okay and never understand why they should not commit that crime and continue doing it. For instance, murder is a crime that many people do not commit because they can sympathize and feel the pain a victim is going through. However, these emotions are gone in a psychopath and they do not feel bad or guilty over the murder. They do not second guess and are ruthless and are unpredictable because society does not know what they will do next. Psychopaths lack a moral compass and, without proper and right morals, they are capable of harming people.

This easiness to hurt other people evokes fear of psychopaths because society does not know when a psychopath will finally say “no, this is unfair to this person” or “no, I should not do this” since they lack sympathy. Humans rely on other human beings’ ability to sympathize and feel for another and second guess their decision, but when that is shut off, they are capable of anything because they feel no guilt.

They are like robots, without any emotions and, therefore, can do anything and are unpredictable. This unpredictability is another factor that scares society because they can harm a person without any motive and they act totally normal, making it hardier to link them to the crime. Additionally, psychopaths are charming and deceitful liars that blend extremely well in society therefore, they are hard to detect and diagnosising psychopathic behavior is difficult.

Furthermore, society portrays psychopaths as crazy, murderous predators in the media which also enforces a dangerous mindset of psychopaths in people’s minds.

With such limited information on psychopaths, difficulty diagnosising the behavior and the lack of feeling guilt and sympathizing, psychopaths evoke fear in society. If you knew a person who did not feel any emotion about killing a person, wouldn’t you want to stay as far away from that person as possible?   

Medicating Parkinson's Patients, Yes or No?

BLOG 8: Treatment for Parkinson disease often hinder impulse control in human, therefore patients living with Parkinson disease should NOT be medicated.  Agree or disagree?  Justify your response.

Parkinson’s is an incurable disease that affects the nervous system and causes people to lose control of their muscles. The following chart is a list of the symptoms of Parkinson’s, taken from www.parkinson.ca.

MOST COMMON SYMPTOMS	OTHER SYMPTOMS
• Tremor  • Slowness and stiffness  • Impaired balance  • Rigidity of the muscles	• Fatigue  • Soft speech  • Problems with handwriting  • Stooped posture  • Constipation  • Sleep disturbances

Treatment for Parkinson’s often hinders the patient’s impulse control, however patients living with Parkinson’s should still be medicated if the patient believes the disease is deeply impairing their lives. There are many stages of Parkinson’s and patients cope with their disease in different ways, therefore it is up to the person and whether or not they want to take the treatment. That being said, if a person’s life is unbearable with parkinson’s where they cannot hold a job, cannot have a happy life and are desperate for a solution, they should be given the option of medication. If a person is given all the pros and cons of the medication, they should be able to decide whether or not the risk is worth taking. If their parkinson’s is just the tremors, slowness and stiffness but are still capable of walking, speaking and doing regular daily processes, they do not need the medication. However, if the patient cannot write, speak or sleep then medication should be recommended as it will lead to a better lifestyle.

Another topic brought up in discussion was whether or not parkinson’s victims should hold a job or not. Similar to being deaf or blind, parkinson’s is a disability that should still entitle patients to a job. Since parkinson’s symptoms are tremors, fatigue, stiffness, etc. patients should avoid jobs like a dentist or brain surgeon because they require fine movements, however jobs like a receptionist would be fine.

There are various symptoms of parkinsons that impair its victims differently thus, giving medication is not a yes or no question. It is whether or not the person’s lifestyle would be benefited from taking the medication, even though there are side effects. Treatment for Parkinson’s, even though it may hinder muscle movement, should be taken based on the patient’s desperation for a cure and on their discretion.

Sleep Deprived Students and Limiting Homework

BLOG 7: High school students are sleep deprived, therefore, less homework should be assigned to them.  Agree or disagree?  Discuss your response.

The fact that high school students are deprived could be due to various reasons, such as personal problems, internet addiction, etc., and not just solely on homework amount. However, if the entire argument is solely based on homework amount, I disagree that less homework should be assigned to sleep deprived students. I say this, because homework is essential to learning and making connections, especially in courses like chemistry and math. Repetition and practice allow students to apply theories learned in class, its like the different between watching someone ride a bike and actually riding the bike. The experience is essential. However, students should be able to prioritize which homework from which subject is most important. If students feel comfortable with a certain subject and do not need that practice, they should skip it and move on to more challenging homework. The question is not whether or not less homework should be assigned, it’s about which homework to prioritize and whether or not a teacher should check the homework. Taking that into consideration, teachers should not base their grading on a student and their completion of homework, especially not during high school since most students should be able to differentiate which homework is more important. Teachers should also realize that some students are stronger in a specific subject and will not finish the homework because they are comfortable with it. Teachers should also realize that a student has many other subjects in which the teachers assign homework as well therefore; completion of all homework should not be expected. If homework completion is so important to a teacher, they should allow for “make up” homework in which a student can show the teacher completed homework the following day, if it was not completed on the due date. Furthermore, one of the learning strands is imitative therefore, if a student is struggling with their homework, they should take initiative and ask for help. They are going to university after all, and should be capable of saying “I need help”. Continuing with university, homework is not assigned in it. University is more assignment and exam based and the questions in the university textbook are completed at the students’ discretion, therefore homework is neither a good reflection of university life nor the workplace. As for sleep deprived students, they are teenagers with rebellion phases and mood swings, therefore if they get more homework or less, they still will be sleep deprived since they will just have more time for their internet addition, unwillingness to work, extracurriculars, etc.

Chemotherapy

After the in depth discussion regarding chemotherapy, list the advantages and disadvantages of this treatment. Do you believe that this is an effective method to "cure" cancer? Why or why not? In your opinion, under what circumstances should an individual consider chemotherapy?

Cancer is the uncontrolled dividing of cells due to mutations which develop tumors. These tumors grow and take energy away the body and healthy cells. One way to combat cancer is through chemotherapy which uses chemicals to kill cancerous cells. The following are advantages and disadvantages of chemotherapy:

Advantages:

• potential of successfully eliminating cancerous cells
• Drugs can be used to combat negative side effects

Disadvantages:

• Side effects: hair loss, nauses, loss of apetite, constipation or diareha, painful and weakness in body
• Different Organ problems: heart or kidney problems, lung tissue damage or nerve damage (1)
• chemicals injected into body cannot differentiate from healthy and unhealthy cells
• Expensive and long procedure

Cancer is one of the deadliest illnesses known to mankind and almost anyone affected with it would want to cure it. Although chemotherapy has many side effects, it is a treatment that is offered as a way to decrease cancer cells by sacrificing healthy cells. This choice is definitely up to the person and how they want to deal with their cancer. However, a person who wants to undergo chemotherapy has probably gone through many other treatments before finally wanting to undergo this long, chemically risky process. Furthermore, this is the most widely known cancer killing procedure known to public and, unless more options are available, most people who are in need of a "cure" will go for chemotherapy.

In that sense, those who are ill would rather spend their time with loved ones in the comfort of their own homes rather than in a white-walled hospital room. Additionally, they must consider their age, their chances of survival, their lifestyle, etc. This ultimately comes down to the patient's choice and how they want to spend their few years either fighting or accepting. 

Personally, if I was diagnosed with cancer now or before 35, i would undergo chemotherapy because I have no lived yet and I have family that would encourage me to fight for my life. However, if i was older such as 70+, I would still fight but if I have undergone so many unsuccessful treatments, I would accept my cancer and continue living my life and preparing myself and my loved ones within the limited time i have.

IPS cells: Induced Pluripotent Stem Cells

 Discuss the significance of iPS cells in stem cell research. Do you believe it would be better to use replace embryonic stem cells with iPS cells despite the success embryonic stem cells already have? What are the advantages or disadvantages? What problems do you think could occur with the usage of iPS cells? And how do you think we can solve these problems? What do you think about the possibility of clones with iPS cells? Could they be abused?

IPS cells are cells that can potentially replace the use of ethnically problematic stem cells retrieved from embryos. Embryonic stem cells are cells created from the fertilization of an egg with a sperm that then duplicates into stem cells. These stem cells then differentiate into various cells needed for the body. These stem cells are highly versatile since they can be scientifically stressed to differentiate into specific cells and then cultured to develop tissues or organs. However, these stem cells can only be retrieved from the umbilical cord which only lasts for a couple of years or from fertilized eggs. 

Problems being to arise when embryonic stem cells are retrieved from fertilized eggs because some say that they are murdering a potential life since some believe that life is conceived once the sperm and egg fertilize. On the other hand, there are many embryonic stem cells that are going to waste such as those fertilized eggs that are used in vitro-fertilization. Once a couple has been successfully impregnated, the previous fertilized eggs are tossed out. Why not cultivate those for stem cells and sacrifice one potential life to save hundreds of others. If that is still an ethically sensitive way of obtaining stem cells, what about those who decide to abort their child even though there already is a mass of stem cells which could be defined as life. These people have, without a doubt, gone through hell to decide to terminate their child and have definitely been told NOT to abort their child however, they have made a choice that will stay with them forever. Since these woman/couples have decided to terminate, why not give them the option to donate the stem cells of their aborted child to science. However, they must NOT be given an incentive to donate the abort child's tissues as this can cause a "kids cash" business where woman continually get pregnant in hopes to sell their stem cells. It should be an option that is done with the purpose of helping mankind, like donating your body to science. If donating a body to science has been effective and accepted, they should be able to create a program for aborted children and stem cells with specific regulations and laws that can be socially accepted into society.

If all these ideas do get turned down, IPS cells are the next best  thing as they are regular cells that have been reprogrammed to revert back into stem cells to be re-differentiated. They have the ability to function just like stem cells which eliminates the ethical concerns linked with using stem cells. Since these cells originate from adult cells, after going through the IPS process, the organ or tissues created will be easily accepted into the original person which means less rejected cells and less money, time and lives wasted. Remember, if an organ that is transplanted into a human being gets rejected, that organ is of no use which could have been implanted in another person to save their life. Other problems from IPS cells are the fact that is a long and expensive procedure, they may increase cancers or viruses, may stop dividing and have a higher rate of cell death (1). Although there are problems with IPS cells, the advantages override the disadvantages of use and scientific research of IPS cells because it is easier to "solve" scientific problems than ethnical and moral concerns that have constantly divided society for so long.

If IPS cells can be used, have such high potential and decrease ethical and moral concerns then IPS CELLS IT IS!

Discuss about the possibility of making an entire human being with the technology we have today. What do you think of it? Would you be able to accept an entirely synthesized human? What are the consequences? Do you think science has a limit?

Creating an entire human being with the technology we have today will be highly unlikely since we are not that advanced today. We may be capable of creating the individual organs via harvesting the cells and incubating them until they form into the organ but we are unable to create a heart or brain that is stable enough for transplant, let alone an actual human. Even if the organs were attainable, the process of connecting viable blood vessels, electrolyte signals and all the chemical needs is impossible in this period of time. Furthermore, the ability to package all the individual pieces in ONE single sheet of human skin that is smooth and "normal" looking is definitely far from our modern day technology. If a human were to be made, i fully believe that it would very much look like Anne Frank's Franklin! 

Since technology and science is rapidly advancing, it could be very possible that synthetic humans can be made-very far into the future that is. So, if these synthetic humans were to roam the earth, i do not believe that i nor others would be capable of accepting it into society as it is "against human growth". The idea that a human was created using stem cells of other people is going against the natural system of human growth. That human would always be considered the "scientific experiment" and become an "art piece" more so than a part of society. Furthermore, the price of synthesizing humans will inevitably cost thousands, millions, billions or even trillions of dollars; money that can be used for more promising things like finding cures and other USEFUL scientific discoveries. Also, the idea of creating a human, naturally, is much easier, simpler and cheaper.

The consequences of a synthesized human for the society that it will bring controversy of the definition of life and god. There will be many groups that will be against that human and new laws for science will have to be created. The human itself may become depressed due to all the negative groups against him and feel like a sojourner. The human will continually question his existence, creating psychological problems. Also, the question is what to do with the synthesized human, treat him like a human and blend it into society or make it a slave to serve us. Furthermore, the human many have needs, desires and urges and will they fall under the human rights act even though they are synthesized. What would happen if they were to procreate, etc? 

Science unfortunately does not have a limit because with every new discovery, new questions are created and thus, more science is needed to be discovered. Science is evolutionary and is therefore, forever changing. The limits for what to do with science is the question. As discussed in class, science is limited to the human capacity of discovering and will ultimately be limited to whether or not society accepts it. Society and the moral rights during that period defines what is accepted. For instance, the discoveries of great women like Barbara McClintok were denied because, during that time, women were incapable of scientific respect. Science is unlimited, human discoveries are unllimited, human capacity is limited and societal acceptance is limited
