CAJ - Worksheet

Which bodies currently fund research into your topic?

I believe that many organizations fighting against certain illnesses fund research into robotic surgeries. Some examples I found are Cancer Research UK, British Association for Cancer Research, Intuitive Surgical and Health Research Funding.

Also, interesting fact, there is an Austrian Center for Medical Innovation and Technology which is located in Wiener Neustadt. They are researching in the field of robotic surgeries too and they are funded by the Austrian Research Promotion Agency, the COMET Competence Centers for Excellent Technologies and the Federal States of Upper and Lower Austria.

Who do you think should fund research into your topic and why?

I think every countries health department should fund research into this topic because it improves the quality of our lives after surgeries. The costs of after surgical care could be reduced and insurances would not have to pay endlessly for a patient’s recovery. With people recovering quicker from surgeries, companies and employers would not have to wait as long as now until employees would be fit to work again. Surgical robots and research in said field is expensive but I believe that with sufficient funding, there would be huge improvements and ultimately safer surgeries, quicker recovery and lesser costs per surgery.

Does the science in your topic benefit everybody? If so, who does it benefit the most?

Yes, there are many advantages for the patients such as lesser pain, smaller scars, a smaller risk of infections, quicker recovery,... But there are also advantages for the surgeons. Some examples for their benefits are that surgical robots allow them to see their place of surgery from up close, perform precise movements which are crucial for surgeries, balance out tremors which would otherwise mean the end of a surgeons carrier,... With patients recovering quicker, fewer postoperative complications and infections, hospitals can release patients earlier from hospital making room for new patients. Companies could put their employees sooner to work due to their quicker recovery. And so on and so forth.

Overall, I think that patients benefit the most as they have to endure the pain and battle infections with their weakened body. They have to stay in bed forever, taking medication, instead of going back to work or doing things they want to do.

If it does not benefit everybody equally, should society being paying for the research?

Well it does, but even if that were not the case, I still think that as long as more people benefit from it than not, society should fund it. After all even a little funding can make a huge difference.

Did it teach you anything new? If so, which aspects had you not considered before?

In fact, it did. Before watching the TED talk, I was unaware of the long history of surgeries. I never even imagined that people thousands of years back did surgeries as drastic as brain surgeries. To be honest, I also never considered the problems arising with surgeries such as cancer or tumor removals. The idea with the markers is quite brilliant yet it seems so simple. I knew that they could inject it into veins in order to make blood donations or even vaccinations easier. But I was not aware of the fact that you can make a special marker which only connects to a certain kind of cell. I could imagine this would revolutionize the cancer treatment as it gives surgeons the chance to make sure that they removed all of the metastases leaving the body cancer or tumor free. Like Dr. Mohr mentions, this opens up so many possibilities. While lung cancer or prostate cancer belong to those types of cancers that have the highest mortality rate, this could change. Surgeons could simply mark the metastases and follow their roots to the starting point. With the highly developed surgical instruments, surgeons could remove all of the cancer without destroying too much precious tissue surrounding it. And why stop there? By injecting it into the brain, illnesses such as epilepsy could probably be fixed too.

Every area of research has societal factors which limit its progress. How are outside influences impacting research in the field of science you are looking at for your CAJ? Think of as many examples as you can.

Surgical robots are very expensive in their acquisition costs. This could make hospitals or organizations unwilling to invest into robots and their research.

There are always those who do not trust robots because they say they can not understand how robots work therefore they must be bad. And why would you agree in a surgery performed by someone or something you do not trust?

Operating surgical robots is very complicated and needs a lot of practice. Young but especially elder surgeons might be unwilling to invest that much time into it.

Imagine you are leading a team of researchers in your field. How would seek to overcome these societal limitations as much as possible?

I would try to find a way where I can show them that later on surgery robots actually reduce costs and that the advantages of such surgeries outweigh the disadvantages. Furthermore, I would show that these robots essentially just mimic human hand motions. Also people who have successfully undergone a robotic surgery could be asked to speak in favor of this type of surgery. The more, the better. And of course get famous people to agree with me.

Surgeons need to understand that although the training is very time consuming, robotic surgeries open up so many opportunities for surgeries and therefore the surgeons. Plus you could make the training fun, as it is already done by some universities.

First Name	Surname	Their topic	How does it connect to yours?	Working link to their CAJ
Fabio	Nitsche	AI; bio-hacking	These enhancements of the human body have to be implanted somehow and how better to do that than by surgical robots? These robots allow surgeons to for instance connect nerves better to implants.	http://fabiotheitalianblob.blogspot.co.at
Natascha	Ramic	Neuroscience	Surgical robots make it easier to perform surgeries especially in areas where human eyes can hardly see anything and cutting movements would be too big and severe. The robot camera can enlarge the video it takes giving surgeons a better few at tiny things even nerves. And while human hand movements are rougher, the surgical robot can transmit them into minute movements.	http://natisenglishadventures.blogspot.co.at
Monika	Toma	Designer Babies	This CAJ talks about the creation of designer babies. But what if during the pregnancy complications arise? Such as the wrapping of the umbilical cord around the fetuses neck, a heart malfunction or even Spina Bifida. Now many complications mean either losing the baby or delivering it premature. With surgical robots, surgeons could perform procedures on the baby still inside the womb increasing it’s chances to survive.	http://monito91.blogspot.co.at/

CAJ - TED Talk

As you all know, we had to look for a TED talk concerning a topic. I found one by Dr. Catherine Mohr who talks about the history of surgery and more important about robotic surgery. Dr. Mohr is a Senior Director, Medical Research at Intuitive Surgical, which is the company that develops the da Vinci robots. She is responsible for the development of new robotic procedures and does her best to improve the risks of surgeries for patients.

In her TED talk, she talks about surgeries and robotic surgeries. She starts by talking about the history of surgery in general and later focuses on robotic surgeries and the future improvements. I really enjoyed the video as it is easy to understand and highly interesting. At least in my opinion. I hope you like it as much as I did. However, if you are not good with blood and/or videos of surgeries then you might want to skip this TED talk.

Here's the promised link to Dr. Mohr's talk:

CAJ - Average Joe and surgical robots in 2039

It is an early morning in the year 2039 and Mr. Doe casually enters the hospital. The hospital, which was once swamped with waiting patients, stressed nurses and busy looking doctors, seems almost empty. Most patients are either in preparation for their surgeries, in the recovery room or on their way home again. The number of nurses as well as doctors has been reduced to a minimum. The main work in this hospital is done by robots. They observe patients, prepare them for surgery and even perform them. Mr. Doe is one of the ten doctors still working in this hospital. Nowadays, their job is more focused on the robots than on the patients themselves. Under the experienced surgeons‘ watchful eyes, 50 robots perform 50 surgeries making waiting patients a phenomenon of the past. All Mr. Doe and his colleagues have to do is to keep an eye on five screens each to make sure every surgery goes according to plan. In the early days of surgical robots, surgeons still had to operate the machines themselves but gradually the robots evolved. Very soon, they were able to perform simple surgeries on their own and all the doctors had to do was to take over in case of emergencies or problems. However, the robots adapted quickly and could handle more complex surgeries and even complications, reducing the surgeons to the role of mere observers. Even though this lead to the near extinction of the medical professions, the advantages outweigh the downsides. Patients do not have to wait endlessly for a surgery anymore, risks during and after surgeries have been reduced, the recovery time is only a small fraction of the time it used to be after surgeries performed by human doctors.

CAJ - da Vinci Training

When surgeons decide they want to operate the da Vinci robot, they have to undergo an intensive training. It takes quite a lot of time and practice to master the skills necessary. The training typically is comprised of three main parts: learning about the technology behind the robot, teaming up with an experienced da Vinci robot surgeon and observing him, and practicing on the robot themselves.

1. It is important for surgeons in training to have a general knowledge of the da Vinci robot and its capabilities. This is achieved by driving the system, watching live surgeries to learn about the actual use of the robot and the techniques used by the surgeons, as well as teaming up with experienced surgeons.
2. After the surgeons have gathered a first impression of the da Vinci robot, they start their proper training. They have to learn about the mechanics behind the robot, practice operating the machine and the special techniques used for certain surgeries. To get a good grasp for the latter, surgeons can either watch full-length procedure videos, shadow an experienced surgeon or attend a special training center.
3. Once the theoretical part of the training is over, the surgeons are ready for their first robot assisted surgery. This surgery is overseen by a supervisor who makes sure that all the techniques are done correctly. The supervisor also has to asses the surgeon and to decide whether he is fit for solo surgeries.
4. When the proctor has given his or her go, the surgeon may perform surgeries with the da Vinci robot. However, it is important for the surgeons to work on their skills.

After extensive training, surgeons are able to do minute movements and they can even build tiny paper airplanes. Further down, you'll find a video showing a Seattle doctor folding a paper airplane with a da Vinci robot in order to improve his skills. If you like it, feel free to look up some more videos. I can assure you, there are plenty of them and they are fascinating.

CAJ - Disadvantages of and Problems with Robotic Surgery

I have talked about the advantages of robotic surgery before but unfortunately every medal has two sides. Therefore I also want to mention the disadvantages and problems associated with surgical robots.

For the hospitals:
One of the main disadvantages when it comes to surgical robots are their astronomical costs. Buying a new daVinci robot for instance costs about 2 million $ which makes it impossible for many hospitals to buy. Robotic surgery takes more time than regular surgery. A heart surgery with a robot can take almost twice as long as a regular heart surgery but the actual time depends on the surgeons' practice with the equipment and their expertise. Because the procedure takes so long, more anesthesia and staff is needed, raising the costs again.
As surgical robots are quite large, they take up a lot of room. In an operating room with lots of instruments and stuff this could lead to problems should complications arise forcing surgeons to step in quickly.

For the surgeons:
Another drawback is the extensive time it takes for surgeons to master working with surgical robots. It takes endless hours of observing and practicing until a surgeon is ready to perform surgery on an actual person.
With further developments of surgical robots, it is likely that less staff is needed. This could lead to two possible consequences. Either it allows them to perform surgery on more patients or the number of staff needs to be reduced leading to the letting go of physicians or nurses.

For the patients:
According to several law firms, there have been several complications with the daVinci robot. Some consequences are burns due to electrical shocks, punctured vessels or organs, excessive bleeding, intestinal tearing, uterus lacerations (which is a rupture of the uterine) and even death. The company Intuitive, the producer of the daVinci robot, are currently looking into that matter and work on locating and correcting any flaws of their robots.

CAJ - Advantages of Robotic Surgery

When you are in need of a surgery, you obviously want the best surgeons for the job. You want to know their faces, know they know what they do and trust them and their abilities. But why should you agree on the use of surgical robots? If the surgeons can do their job, why should you want a robot to perform surgery on you even if he is operated by those surgeons. A similar question can be asked by hospitals. Why should they invest tons of money when all they get is a machine who has to be operated by surgeons? If I have the surgeons and they do a fine job, why the extra investment?
In this post I will tell you some advantages of surgical robots and why maybe choosing a robotic surgery over a regular one might not be such a bad idea.

For the patients:
Patients who undergo robotic surgery usually recover quicker than those of a regular surgery. This is due to the fact that a robotic surgery is less exhausting and traumatizing for the human body. While regular surgeries are usually done through one large incision, robotic surgery can be performed through several smaller ones. If you take the example of a heart surgery. In a regular heart surgery, the patients chest needs to be "cracked open" meaning that a roughly 30 cm long incision is made in the center of the the chest. This incision severs the muscles which hold the rib cages together.

Sounds pretty painful, right? In a heart surgery performed with surgical robots, all it takes are three or four incisions (all about one cm long) in between the ribs.

This allows the surgeons to access the heart without having to break through the chest. The smaller incisions mean less pain and bleeding for the patient and the risk of infections is also reduced. Overall, the incisions heal quicker because of their size meaning that the patient recovers faster and is sooner able to live his normal life again. Plus, a shorter hospital stay and quicker recovery also saves money.

For the surgeons:
Surgeries, especially complicated ones, are very time consuming and exhausting for surgeons. They have to be fully concentrated the whole time as even a tiny slip with the surgical instruments could have catastrophic consequences. A huge problem for surgeons are hand tremors which can occur during long surgeries. A tremor is an involuntary shaking movement which can be really bad if it happens during a surgery where surgeons need to make minute movements. Usually these tremors, especially if they occur regularly, mean the end of a surgeons active career as it would be unsafe for patients and the hospital would fear law suits. Surgical robots, however, can ignore these tremors as the movements are small and the robot only reacts to bigger ones. When the surgeon's hand has a tremor, the robotic arm stays still. With surgical robots, a tremor no longer equals the end of a surgeon's career.
Surgeons are, despite their reputation, only human. And like every human they sometimes need to sneeze or something itches. During regular surgeries, this would be a problem as the surgeons have their surgical instruments in their hands and those instruments need to stay in place. While operating a surgical robot, surgeons can simply let go of the machine and the robotic arms stay where they are.
Another major benefit is that the surgical robot gives physicians a better few and access to the site of surgery. The surgeons have a 3D image of the patient's inside in front of them and the robot mimics the movements of their hands making robotic surgery easier and more natural for surgeons than laparoscopic surgery.

For the hospitals:
For a regular surgery, even a simple one, you need two or three surgeons, an anesthesiologist and several nurses. That's a lot of staff. Robotic surgery requires fewer people to be in the operating room. This lowers the costs for each surgery and allows them to take care of more patients.

As stated above, patients recover quicker. This allows hospitals to discharge them sooner, reducing costs too.


You say, there are plenty of benefits coming from robotic surgery and for my part, they had me at "lesser pain".

Expository text - How does instant photography work?

When I was a kid, my parents used to have a polaroid camera. They took pictures and shortly afterwards the image magically appeared. For those of you who, very much like me, have always wondered how this was even possible, here is the explanation.

Instant film or film for polaroid cameras is very similar to regular film. The main difference between the two of them is the developing process. While a regular film has to be developed externally, in a dark room, the instant film already has all the needed chemicals in its layers. Therefore, the picture develops as soon as it's been taken.

The film itself comprises of several different layers, as you can see in the image.

When a photograph is taken, the silver atoms on the film react with the light photons and create an image. In order to get a real picture, it needs to be developed. For this, rollers inside the instant camera spread the reagent layer, which is made of opacifiers (light-blockers), alkali (acid neutralizers), white pigment and other elements.

Underneath the reagent layer, there are three different light sensitive layers (blue, green and red). Under each of them lies a dye developer in its complementary color (yellow, magenta and cyan respectively). When a certain color of light reaches its sensitive layer, the opacifiers block the dye developer right underneath it. The other two developers can move up to the image layer.

This means that if blue light hits the blue sensitive layer, the yellow dye developer gets blocked. Therefore, only magenta and cyan reach the image layer, creating the color blue.

If you have ever seen an instant photograph develop, you know that it is usually greyish at first and only slowly becomes visible. This is due to the opacifiers. The reagent chemicals not only work their way down through the dye developers but also up through the image, timing and acid layer. The picture will stay greyish until the opacifiers and the alkali reach the acid layer where they react. This reaction makes the opacifiers become invisible and the picture visible. The timing layer slows the reagent chemicals down, leaving the picture underneath enough time to develop.

And voila, that is how instant films work. You see, it, unfortunately, has nothing to do with magic after all. 

CAJ - Different Types of Robotic Surgery

In an earlier blog post, I have explained what laparoscopic and robotic surgeries are. Now I want to tell you a little bit more about the different areas where robotic surgery can be used.

Although robotic surgery is most commonly known for being used in the abdomen area, it can essentially be used for every body part as long as you can make an incision there and insert the surgical instruments. The reason why it is mostly known for abdomen surgeries is that there are many organs in this area and the first laparoscopic surgeries where performed in this part of the body too. The surgeons knew where every organ was and had easy access in case something went wrong.

Nowadays, even heart surgeries are often performed by a surgical robot as it reduces the risks for the patients since the incisions are smaller, there is no need to crack open the chest and the surgery is being performed on the beating heart.

Even surgeries on spine or brain are no longer a problem. The University of Maryland developed a brain surgery robot that removes brain tumors safer as the machine works together with an MRI scanner granting the surgeons a better view of the tumor. This makes it easier for the surgeons to remove the tumor without endangering or harming the healthy cells surrounding it.

Overall, robotic surgery can be performed on almost every part of the body. If you can name it, it has probably already been done before. The reason why surgeons are so eager to use robotic surgery is that there are many advantages to it which allow them to perform surgeries better and more efficient and to sink risks and the amount of pain for the patients.

CAJ - Laparoscopic or Minimally Invasive Surgeries

In former times, when you underwent surgery, you usually got a souvenir in form of a huge nasty scar. Every scar is a remainder of a incision. The larger the incision the longer the healing process. They are also accompanied by a large amount of pain and a high risk of infections. Therefore, doctors are always looking for a way to keep the incisions as small and their number as low as possible. As a solution, surgeons developed the laparoscopic or minimally invasive surgery. It is also known as keyhole surgery due to the small size of the incisions. This type of surgery allows surgeons to perform operations inside the abdomen. Instead of one large incision, several smaller incisions (between 0,5-1,5 cm) are made and plastic tubes are inserted. Through these tubes, surgeons can insert cameras and surgical instruments.

The camera then transmits pictures of the patients inside on a screen for the surgeon and his team to see. Unlike in an open surgery, the surgeon does not see the organ from a top down perspective. The camera rather acts as the surgeons eye allowing him or her to inspect the organ up close and from different perspectives.

However, there is a major limitation the laparascopic surgeries: the surgeon can only work with his or her instruments and can not use his or her hands for help. For instance, the surgeon can not simply push the intestines or organs from the site of surgery as would be the case in an open surgery.
To increase the accessibility of the organ, there have been some improvements to the laparoscopic surgery, namely the advanced laparoscopic surgery with hand-access devices and robot assisted surgery.
In the advanced laparoscopic surgery, a larger incision is made, large enough for a hand to fit through and again a plastic tube is inserted. This allows the surgeon to use his hands and tactile sensation for the surgery.

The robot assisted surgery, as mentioned in the other CAJ posts, turns the surgery into a kind of video game. The surgeons sit in front of a screen with the instruments at their hands. They then performs the surgery as if it were a regular laparoscopic or open surgery with the difference that the patient does not lie right in front of them.
Basically, that is all you need to know about minimally invasive surgery. It is a good way to minimize the risks associated with surgeries and scars and although there are some drawbacks, scientists and medics are working hard to get rid of them.

CAJ - History of Robotic Surgery

The word robot comes from the Czech word "robota" and means forced labor. The term was coined by the Czech playright Karel Capek. While the robots used to be primative machines, they have come a long way since then. Nowadays, robots are able to do more complex tasks such as performing surgery.
The first documented robot-assisted surgery was performed in 1985. It was a neurosurgical biopsy and the robot PUMA 560 was used. The surgeons decided on the use of PUMA 560 because it allowed them to perform the delicate biopsy with greater precision.
                                 

In 1987, the first laparoscopic surgery was performed. It was a cholescystecotomy which is the removal of the gallbladder. Since then, robot-assisted laparoscopic surgeries, also known as minimally invasive surgeries, have been performed numerously. Laparoscopic surgeries are surgeries performed in the abdomen where the area is accessed through several small incisions instead of one large incision.



Surgery robots were revolutionized in 2000 when the FDA, the Food and Drug Administration, approved the robotic surgery system da Vinci Surgery System. The former surgical robots were large-armed and surgeons needed endoscopes and numerous surgical assistants in order to perform surgery. The da Vinci Surgery System, however, is an all-encompassing system of surgical instruments and camera or scopic utensils.

As you see, robotic surgery is not so new as you might think. What started as a large armed robot has become a multi-armed machine which allows surgeons to perform even really complex surgeries with great precision. It is only a matter of time until they are able to perform surgeries completely on their own.

How to stop someone from killing Hitler

Estimated time: several years

Needed equipment: a time machine, a history book, charisma, CPR skills

1. Look up in your history book where and when Hitler was killed and by whom.
2. Think of several plans on how you can save Hitler.
3. Pick a date and time when you want to meet Hitler.

Tip: Choose a date a couple of years prior to the assassination. This leaves you with enough time to befriend Hitler and become one of his closest companions. This way he will always keep you close by, improving the chance of you being able to save him.

4. If you have decided on the ideal day to meet him, set the time machine to said date.
5. Enter the time machine and travel back.

Tip: Always keep your time machine close by in case you need a redo or to abort the mission.

6. Meet Hitler and try to become friends with him right away.
7. If he does not like you immediately, stay consistent. If necessary, join the military and slowly work your way up.

Warning: The latter might involve hard work and violence. If you feel uncomfortable with either, abort mission.

8. Once you have successfully become Hitler’s best friend, follow him everywhere.
9. When the day of the planned assassination arrives, you have two choices: take care of the assassinator before he gets the chance to kill Hitler or let him try and revive Hitler afterwards.

Tip: If you choose the first option, your deed will probably go unnoticed. Choosing the latter option, however, will make you a national hero and Hitler will forever be in your debt.

10. If you choose the first option, locate the suspect and rid yourself of him. This is best achieved by tipping off the Gestapo and he will either be arrested and/or shot. Your job is done and you return to your own time.
11. If you would rather become a hero and take all the glory, let the perpetrator try to kill Hitler.
1. Revive Hitler.

Tip: If you do not get it right the first time, wait until you are alone and travel back in time. Repeat until you manage to save Hitler.

12. Congratulations! You have now successfully saved Hitler’s life.

Camera Lucida - How helpful were the instructions?

Tim Hunkin’s instructions on how to make a camera lucida appear to be easy to follow due to the pictures and the text accompanying them. However, the set of instructions turns out to be rather confusing when examined more closely. Firstly, the instructions given are incomplete. For example, the instructions mention a hole to look through although said hole was never mentioned before. Similarly, the installation of the reflecting plastic plate is missing. The author probably left these steps out purposely as they seemed obvious to him. To someone who has never  built a camera lucida before, however, these steps are essential. It would also have been more helpful to number the steps, even if the text is very short. Another confusing aspect that the reader constantly has to jump between the text and the pictures. Neither text nor pictures are sufficient on their own to explain how the camera is built without causing utter confusion. Overall, the text itself is not badly written. It is concise and understandable, but the fact that it is only partially complete makes the instructions rather difficult to follow.

CAJ - Abstract

This CAJ looks into the field of surgical robots, such as the DaVinci robot, and the surgeries which are already practiced by them. Furthermore, it focuses on the extensive training surgeons have to undergo to operate these robots and the advantages as well as the disadvantages of the surgical robots themselves. The CAJ gathers its information from videos, special blogs as well as academic papers. It comes to the conclusion that although the training for the surgeons is very time consuming and the robots are expensive, risks and complications have dropped significantly for the patients. They recover quicker, are able to leave the hospital earlier and overall encounter less pain. Overall, surgical robots hold many advantages for the patients which is why they are likely to spread and become used more frequently.

CAJ - Introduction

As my CAJ topic, I've decided to choose the DaVinci robot. It is a surgical robot which allows surgeons to perform complicated surgeries even better, comes with fewer side effects than regular surgery and is already in use for a variety of surgeries. Over the semester, I will talk about the advantages as well as the disadvantages of surgical robots, the complex, yet pretty awesome training surgeons have to go through in order to be able to operate the robot, and what kind of surgeries are already possible with it. So look forward to the next blog posts because it's a pretty interesting topic and let's be honest, who wouldn't want their surgery done by a nice Dr. DaVinci turning your surgery into a kind of video game?! ;)

Napalm Girl Descriptive: Group 2

This black and white picture was taken during a napalm attack during the Vietnam War in 1972. The landscape is bare save for an overgrown field and a few buildings in the background. In the centre of the picture is a young naked girl, a haunting scream on her face as she runs down a cracked asphalt street from the enormous cloud of smoke behind her. She is surrounded by five clothed children and four armed and uniformed soldiers. The children wear terrified expressions on their faces, whereas the soldiers do not look particularly frightened to the naked eye. The malicious dark colour of the cloud, when compared to the light gray of the street leading the
innocent children into safety from the ever closer growing danger, makes the situation look even more bleak.The picture is devoid of colour but full of life nonetheless. The children’s screams resonate in the viewer’s ears, as does the rumble of the ongoing air raid and humanity’s inherent fear of their own demise is reflected in the children’s faces. The poisonous cloud seems to have a life of its own as it appears to close in on its terrified victims, rendering the viewers unable to tear their eyes away from the scene in fear that the break in eye contact will set the scene into motion.

Narrative article homework

Mai-Lin Xi sits in the lobby of a hotel in Beijing with her two year old daughter on her lap. She clings on to her and holds her tight. With red eyes and quivering voice she says, „It has been almost four weeks now and there still has been no sign of life. I miss him so much. My daughter keeps asking me about her daddy and I have no idea what to tell her.“ Mai-Lin talks about her husband Zuko who is one of the passengers of the flight MH 370. Like many others, Mai-Lin has been waiting in a hotel close to the airport ever since the plane went missing. The families of those missing try to support each other but the more time passes, the harder it becomes to hope for a happy ending. „We just want to know what happened. We want to put an end to this nightmare and return to our lives again“, mumbles an old lady next to Mai-Lin.

Article Analysis

In the article "Whoa, Dude, Are We Inside a Computer Right Now?", written by Ben Makuch and published on September 11, 2012 on the website Vice, Makuch tries to answer the question whether we could be living in a computer simulation or not. For his arguments, he mainly uses ethos and logos. Especially in the first part, where he introduces Rich Terrile, he informs the reader about Terrile's achievements. Makuch states that Terrile is a "well regarded scientist, the director of the Center for Evolutionary Computation and Automated Design at NASA's Jet Propulsion Laboratory". Furthermore, he ends his second paragraph by saying "so we‘re going to go ahead and take him seriously". In the second part of the text logos becomes more important. Terrile gives examples supporting the computer simulation theory. For instance, he argues that "the universe is pixelated" which means everything can not be broken down further than into a fundamental unit. He also mentions that by the rate our technology improves very soon, in 30 years, we will have computers strong enough to simulate our world. These logical arguments as well as the Ethos used in the beginning of the text make it highly credible and convincing.

A day in the life of a guardian angel!

She stirs. I know her daily routine by heart now. Her struggle to get out of bed. At last, she manages, sits up and rubs the sleep out of her eyes. I have not slept for a minute. My sleep could mean her harm. She loves to toss and turn and she could easily bump against a shelf or a wall or fall of her bed. I‘m telling you, this human is unbelievable. I once fell asleep during a night shift, just for a second, and she almost fell of a bumper bed. The top, not the bottom one.

I never leave her side. I spent my mornings watching over her very closely. While she eats, walks her dogs, goes to uni and to work. Those mornings are always stressful for me. There are so many dangers. Wether it is bumping against something or slipping and falling. The afternoons are usually more relaxed. My human loves to read and listen to music. These activities usually hold little risk for her to accidentally hurt herself. Even IF she‘s horribly clumsy.

Soon afterwards, another day ends. And although it‘s a never ending story, protecting her every second, I can‘t really complain. After all, I do love my job and my clumsy human.
