That’s a wrap! The polymer project came to an end and finally the product was created! Our product: The Phonatic Corners (that’s a pun/joke) polymer is finally produced, and it had been declared a success. The original goal of our product is to create four corner attachments for a phone, and it should have a high energy return and good for shock absorption. This corner attachment will go on a phone and hold it’s form, and the sole purpose of the product is to protect the phone from hitting the floor. From the beginning we knew that broken screens are extremely common and we want to bring an evolution to phone development – a product that can protect the phone from dropping on the floor too hard and breaking it.

 

We started experimenting with polymers soon to find a polymer that can be attached onto a phone and protect the phone. So we tried Gloop and failed many times, problems like cannot stick onto the phone or does not have enough energy return. Finally, we found out over many tests and trails, liquid starch, that we added with borax (suppose to make the product more solid) had made the polymer wet and hard to work with. After many trails and tests, we found out a combination of Booger and Gloop with extra borax solution works great. This polymer can hold its form, can bounce and can be attached onto a phone easily.

 

Our final product was a polymer that combines the pros of the both worlds from Gloop and Booger. They both start with glue but one uses liquid starch and one uses borax solution, we separate borax and piqued starch so that it doesn’t become wet and slippery. Gloop is more bouncy and solid while Booger is more sticky, so we added liquid starch into an amount of glue, and borax solution into another amount of glue, then we mixed it together before it turned solid and we got a good polymer that has the characteristics of both worlds.

 

We attached the polymer onto a phone and did drop tests, starting from 10cm height, add 5cm to the height each time, finally to 1.25m. It was very successful and we found the polymer did give the drop a high-energy return and the phone survived the 1.25m-drop test 3 times on concrete floor. Declaring a success.

 

During the “Dream On” presentation day, I learned, from many other people’s presentations that engineering is hard, and you can’t always achieve what you want. Many people had good ideas and clear goals, but the product was not desired. This proves that engineering can’t always be successful, but you have to optimize what you have and redesign you have another chance. Our product was successful, so this concludes the polymer project with a success.

Spending a year and half all by yourself on a planet is tough, and you have to live with the supplies that is suppose to last only 30 days. The Martian by Andy Weir is about an astronaut – Mark Watney was one of the first people to go to Mars and do mission for 30 sols. The United States Congress funded for 5 Ares missions, where 6-crew member at a time gets send to Mars via a huge ion engine space station called Hermes. Ares 1 and 2 was a success, but Ares 3, Watney’s mission was aborted 6 sols into the mission because of a storm that was 175kph. The base cannot take the punishment of the huge scaled sandstorm. They had to leave via a rocket called the MAV, the Mars Ascent Vehicle. During the emergency launch, Watney didn’t make it to the MAV; he got hit by an antenna on the way and was thought dead. He now has to face the problems Mars will offer him and finally find a way home.

 

The theme of the book is: If a problem exists, so does a solution. In the book, Mark had to face billions of problems, and every one of them had to be solved to let him go home. “So that’s the situation. I’m stuck on Mars. I have no way to communicate with Hermes or Earth. Everyone thinks I’m dead. The next mission to visit Mars is on Sol 1412. I’m in a Hab designed to last thirty-one sols. I’ll eventually run out of food and starve to death.” (Weir, 7). This is saying he need to survive to sol 1412 to be rescued, but the resources and the base he is in can only last 31 sols.

 

Quite hopeless right?

 

However, he knew that Mars will not cooperate with him and kept trying after problems and problems, even into fatal problems that he knew he couldn’t escape. He sad a situation where the airlock blew up and he will suffocate after the air run out, and he had no way to escape. “All I have to do it sit here. The air will leak out and I’ll die. I’ll be done. No more getting my hopes up, no more self-delusion, and no more problem-solving.” (Weir, 158). He was desperate, however, he calmed himself down and finally found a way to seal the leak, then took all night to get back to the Hab and add in more air. “I’m alive! And I’m in the rover! Equalizing the airlock went fine.” (Weir, 167). This proves that no matter how bad the problem is, there is always a solution. In the movie, Watney said at last: “Yes. Absolutely I thought I was going to die. This is space. It does not cooperate. At some point, everything is going to go south on you. But you can get to work. You do the math, you solve one problem, and then you solve the next one. Then if you solve enough problems, you get to come home.” (Scott, 2: 12: 40 – 2: 13: 25).

 

Again, if a problem exists, so does a solution. The odds were stacked against him, it is space, and it does not cooperate. He faced fatal and desperate problems that he knew will kill him. Any failure can result in death. Mark Watney, one of the firsts to visit Mars, now the first to sure die on Mars, needs to solve problems after problem to get home safely.

A Mission Failure

Posted by: | May 3, 2016 | No Comment |

Screen Shot 2016-05-03 at 8.05.54 AM

The Ares 3 Mission was a failure, a big one. The Martian by Andy Weir is about a future manned mission to Mars, and the United States Congress funded for 5 Ares Missions to Mars. Ares 3, with the member Mark Watney, successfully landed on Mars. However, they got hit by a 175kph sandstorm and they had to do a emergency launch. Unfortunately, Watney was hit by a flying antenna during the walk to the MAV (Mars Ascent Vehicle), and was thought dead. He need to tell people back on Earth that he is still alive and find a way to be Rescued.

This book cover I designed has a red Mars background. Also has a comment and author with other messages at the bottom of the book.

One Man On A Planet

Posted by: | May 3, 2016 | No Comment |

“I don’t want to come off as arrogant here, but I’m the best botanist on the planet!”

– Mark Watney (Weir, 146)

 

The Martian by Andy Weir is about a future mission that took place in about 2030s called the Ares Program, which is the first manned mars landing mission. The United States Congress funded NASA for five Ares Missions. All missions uses a huge interplanetary ion-engine space station called Hermes (The god of travelling). Hermes sends the crew members (6 members each mission) of each mission to Mars, where there, they will have supplies to build a base sent by 14 unmanned supplying missions before the crew arrives. Each Ares Mission let the crew stay on Mars and study for a 30 sols, then leave via the Mars Ascent Vehicle. The MAV (Mars Ascent Vehicle) launches the crew members into low Mars orbit, then it will dock with Hermes and go back to Earth.

 

Ares one and two was a great success. However, Ares 3 with the member: Botanist/Engineer Mark Watney, Vogel, Beck, Johanssen, Martinez and Commander Lewis’s mission caught a huge sandstorm on sol 6, the wind got up to 175kph and the MAV rocket might tip if the wind got bigger. This forced them to abandon their mission and to do an emergency launch. Everyone made it to the MAV but Watney, who on the way got hit by an antenna and was thought dead. When he woke up, he found out, of course, the MAV was gone. He had to face a million problems and to work out how to contact NASA, because the antenna broke during the storm and find a way to be rescued.

 

Mark Watney is a very humorous person, often good with jokes (mostly dark jokes). “Also, he’s a good-natured man. Usually cheerful, with a great sense of humor. He’s quick with a joke.” (Weir, 89). This was an interview back at NASA with the psychologist working with the Ares crewmembers. Also, Mark is a very positive guy who cheers up the crew and makes them all work better. “In the months leading up to launch, the crew was put through a grueling training schedule. They all showed signs of stress and moodiness. Mark was no exception, but the way he showed it was to crack more jokes and get everyone laughing.” (Weir, 89). This is also from the psychologist’s view of Watney. Watney also has a very impatient and over self-confident personality, who refuses listen to NASA’s million super-smart engineer’s advices, thinking he can do it himself. “NASA has a lot of ultra-smart people and I should really do that they say. If Commander Lewis was here, I’d do whatever she said, no problem. But a committee of faceless bureaucrats back on Earth? Sorry, I’m just having a tough time with it.” (Weir, 153). This was Watney’s response on NASA’s advice on “don’t take the water declaimer apart.”

 

Watney is a very smart guy who is very positive and humorous. Mars doesn’t cooperate with him. He needs to gather all his intelligence and courage to face the Planet of Death. Anything that go wrong can kill him, and he needs to overcome those tough problems and finally find a way to leave Mars and go home.

The final prototype of the polymer project was created today. We made 3 prototypes in total:

P1:

  • 1 cm high of glue in a plastic cup
  • 4ml of water
  • 12ml of borax solution
  • 3ml of liquid starch
  • Mold for a few minutes

Prototype one was a modification on Gloop, less water (intended to make the product more solid), more borax (intended to make the product to have more energy return) and added liquid starch (intended to make the product less stringy, or more solid). The result was not very intended, the product was too wet, and it cannot be molded together. This was bad, because to produce a solid phone corner that has high energy return has to be dry and stable, or else the liquid might damage the internal electric instruments in the phone. The analyses was the water made the product too wet and made the glue less sticky so that it cannot be molded together. So I’m removing water in the next prototype.

Prototype 1 - too wet

Prototype 1 – too wet

P2:

  • 1 cm high of glue in a plastic cup
  • 15ml of borax solution
  • 3ml of liquid starch
  • Mold for a few minutes

Prototype 2 had an interesting outcome. This prototype cannot be molded together, so that’s bad, and it’s not sticky anymore, so it cannot even be attached onto a phone. However, this prototype had many layers, so it is good for absorbing shock.

Prototype 2 - with its many layers

Prototype 2 – with its many layers

P3:

  • 1 cm high of glue in a plastic cup
  • 10ml of liquid starch
  • Product sprayed/mixed with corn starch
  • Mold for a few minutes

The final prototype was Booger with modifications. We used booger this time because Booger is stick and also has a high-energy return, so it might be better to stick into a phone. However, Booger deforms itself overtime, which is bad, so we added cornstarch to make it more solid, and the problem was effectively solved.

Prototype 3 - sticky and high-energy return

Prototype 3 – sticky and high-energy return

The final prototype (3) was what we chose, because it is sticky and can hold its form, which can be molded onto a phone and stay on a phone. It also has a high-energy return, which can absorb shock and force and protect the phone. We tested with a phone from 1.2-meter drop height. We made four prototype 3 polymers and molded onto an iPhone 6s 4 corners; it had survived the drop height onto a concrete floor 3 times, declaring a success.

After the test of four different polymers: Oobleck, Gloop, Booger and Super Slime with slime tests, we gathered results and found interesting characters in each type of polymer:

Results of Polymers

My best hope for the desired effect will be gloop; it is bouncy and will hold its form from hanging and hard to snap. This will be very effective for my project because a corner attachment have to hold its shape and also needs to bounce, so this polymer will work great. However, I do need to make some changes to make it extra bouncy and more solid. First, add borax, because this substance will make the product more bouncy and harder to stretch, which is good. Also, I’ll add in some liquid starch, because it will make the product less stringy. Finally, I’m decreasing the water amount in the mix to make it as solid as possible, or maybe even replace water with liquid starch.

 

Those materials mixed together should create a solid, clay like material but extremely bouncy. I’ll of course have to test it out. I’m going to measure the weight of an iPhone 6s, and to use cardboard to build a model. I’ll add dummy weight (paper clip or fine gravel) to make the weight equal. I’m going to test it by adding the prototype attachment onto it, and then drop it from 2 meters high. The model is more fragile, and if the fragile model passes the test, then the phone will sure pass as well.

Polymer Idea

A gif showing how the attachment will work

A phone with an attachment that will never break from being dropped will be awesome, you can drop it, smash it or even used it as a bouncy object to play with will do 0 damage to your phone – this attachment will exist soon. My polymer engineering project’s general goal is to create a polymer that will prevent things from breaking, and I’m deciding to create a light corner covering polymer that can absorbs force and protect the phone. Currently, broken screens and smashed phones can’t be more common, and as a interesting study from Personal Electronics Control shows 52% of people break their phone at least once in their life time by dropping them. Our project will create a light corner attachment, like table corner cover, and covers the four corners of any type of phone: iPhone, Samsung, Android and many, many other type of phone. This corner attachment will be made out of polymer and it will prevent phone be broken by dropping it on the ground.

 

This type of polymer corner attachment will appeal to anyone who owns a phone. This product and prevent broken phones of any type by absorbing force, and anyone can own this product and feel safe if they drop their phone. This polymer will be flexible and bouncy. It can be molded onto corners like clay and it will hold its form. This type of polymer will absorb energy so it will protect the phone. It will also have a high-energy return, meaning that when it does hit the ground, it will bounce up. Down is a diagram showing how the polymer will look like then it applies onto the phone.

Different Actions Applied Without this polymer
Dropping on wooden floor Bounce and stops High chance of breaking screen
Dropping on concrete floor Bounce and stops High chance of breaking internal battery
Dropping on tiles Bounce and stops High chance of breaking screen and internal battery
Dropping on lawn Stop on the first hit Stops on the first hit
Throw it at the wall Bounce on the ground and stops Extreme high change of breaking screen and internal battery

The Power of Power

Posted by: | April 19, 2016 | No Comment |

The Power of Power

Kwame Sarfo Aboagye

 

When a man is blessed, or cursed, with power
Do not expect him to be fair and just
Do not expect him to provide for all
Rather expect him to satisfy his own lust
And amass wealth as high as a tower

When a man is blessed, or cursed, with power
Do not expect him to do what he must
Do not expect to him to heed to your call
He cannot have a heart as light as dust
Or be sweet like the nectar of a flower

When a man is blessed, or cursed, with power
He cannot be trusted; neither can he trust
When he is demanded to fight, he stands tall
But finds it more difficult (on this hot crust)
To make peace than to annihilate a land in an hour

When a man is blessed, or cursed, with power
He wants to build for himself a golden bust
Do not expect him to expect to fall
Even the noble ones eventually adjust
In order to succumb to the power of power

Power is nothing more than a very powerful tool that can cause good or bad. I made a Venn diagram to show the differences and similarity about the effects of power when used in a positive way and negative way. My diagram is based on the poem about power: The Power of Power by Kwame Sarfo Aboagye, which is about the negative side of power. To compare, I used the positive side of power’s poem The Power of Positive Thinking by Denis Martindale. I found keywords and key meanings of each poem and put them on each side of the Venn diagram. Power can be used to do good or bad, and both side with power, can cause a big impact.

A Shot Of Parabola

Posted by: | March 21, 2016 | 2 Comments |

This is a blog post about the project quadratics in real life. I videoed a golf shot and an analyzed its parabola.

Video explaining the parabola of the golf chip:

Video

Quadratics Video Parabola Analyst Paragraph:

My parabola was based on a golf chipping shot, it was a negative parabola as the parabola went up and down, containing a maximum and a positive a for he equation. My parabola’s golf shot started at 0, because that is it’s y-intercept and that is where the chip shot began. The vertex of my parabola: first, it had a maximum for the vertex, because a was negative. The vertex form: y = a(x-h)2+k, a is the opening of the parabola, this will affect the opening angel and the bend of the parabola. X is the time axis, which means x will be the time of the ball at a certain height. In a vertex form, -h and k will represent the vertex’s coordinates from the parabola. Note that a negative h is the value for the vertex. –h is the distance of the vertex from the y-axis; moving h will move the whole parabola horizontally. k is the distance of the vertex from the x-axis; moving k will move the whole parabola vertically, k will represent the highest point of the parabola, while –h will represent the time of the highest point of the parabola. In my video, the equation was:

y = -5.4(x-0.5)2+2.4

The h was (-0.5) but –(-0.5) = 0.5, so the value of h was 0.5. k was 2.4, so at 0.5 seconds, the ball’s was at its highest point off the ground, which was 2.4m.

 

This graph is a restricted graph, meaning that the parabola does not go on forever, it’s a bended line, but it’s a bended segment. At zero, the parabola begins, because that is where the ball began and at 3.5 meters from the y-axis, the ball landed, indicating the end of the parabola. The parabola had a restricted value of domain and range, domain is the span for the x-axis, and range is the span for the y-axis. For my parabola, the domain is 0 </= D </= infinite, because at 0 seconds (y-axis), the ball began it’s flight but time can go on so there is no limitation for the end of time. The range is 0 </= R </= infinite, because 0 seconds, the ball began it’s flight but the height of the parabola has also no limitations, so it’s infinite.

 

In real life, there are many examples of restricted graph, like a baseball hit. The ball will start t a point, and at a specific second, the ball will land on the ground. This graph has limitations because the ball/parabola starts at a point and ends at a specific point (end of parabola), so it is restricted. Also like diving, the diver starts on the board (start of parabola), which has a specific point, then dives into the water, the entry point of water marks the end of the parabola, so it’s also restricted. Finally, like a ballistic missile, is also has a restricted parabola. The launch silo will launch the missile (start of parabola) and the missile will fly a very high trajectory into parking orbit and fall back and impact on a specific point (end of parabola). This also has a restricted parabola because the parabola has a restricted start and finish. This is a summery for the parabola I filmed and some examples.
