Technologies always give people a lot of surprise, they will always appear when a new issues has been raised. In the past centuries, wars have been occurring all over the war and one of the major cause after the war is injuries: Some of the soldiers only get scratches but some lose their body parts and this is really a catastrophic to them because before the war they can do a tones other activities with their complete body, but after the war they may some kind of losing most of their lives. As I mentioned, technologies will always give people surprise when people need them. In order to solve this kind of problem, scientists have spend a lot of time and create a machine or semi-robot which may assist disabilities to retrieve “what belongs to them” called Artificial Body Parts.
Currently there are 10 Body part that science is replacing:
- Fingers that store digital files
- Artificial Eyes
- Artificial Pancreas
- Noses That smell Diseases
- 3-D Printed Ears
- Miniature Human Brains
- Thought-Controlled Bionic legs
- Prosthetic Hands That Sense Touch
- Beating Hearts related in a Petri Dish
- Supersensitive Electronic Skin
I am not going to explain all of this 10 body parts to all of you today, but what I am going to show you today is a story about artificial arms. First, Let us see a TED talk by Dean Kamen.
Does it look really cool? Just as Dean Kamen said, the artificial body arm he built is really like the one in terminator and it does met the requirement that DOD gave him, even surpass the requirement. Maybe all of you start wondering if I am going to explain those fascinating technologies that Dean used in those arms, but as the last content I am going to write in this blog series, I would like to try something new: I would like to now what makes him turn the impossible in science to success?
Obviously, from the title of the talk, it is emotion that affect the invention.So our Null hypothesis here is the Emotion has no effect to Dean’s proficiency to build the arm and our Alternative hypothesis is emotion has an effect to Dean’s Proficiency. As we lean from the talk, Dean reject the DOD for the first time when he was assigned the task because all those requirement from DOD was sounded crazy and as a scientist he knew that the requirement is way too far that is impossible to achieved with what he had got. However, emotion, being one of the ways of knowing, stimulus his sympathy and his determination to make it happen. So It is possible that it is the emotion which stimulus Dean’s proficiency because create something people ever accomplished. This hypothesis is non-testable because Dean’s invention process is already passed, so if the alternative stand, it could be false negative or correct. However, because we have no significance evidence that Emotion is the factor which affect Dean’s invention because it was only an anecdote said by himself, it is also possible that Null hypothesis can stand that Dean is not confident about to finished the project at first which he can accomplish by his knowledge. But as far as we learn from Dean, we can really sure about if it is not emotion, Dean will never accept this mission and if he did not accept the mission, he will never built the arms.
Artificial Body parts apparently help to improve people’s life as we could saw from the video that how happy the people react when they got their “arms” back. But there are still a lot of ethical issue we are going discuss further about such as is it ethical make a huge change to a disabilities when he/she has already adapt his/her life without the losing part? However, as far as what we saw, people are happy about this kind of great invention, and thanks to the emotion chemical as a stimulus behind science that makes impossible thing into possible and improve people’s live.
