The Outcast: Volume 1 Chapter 8

Volume One: Eastwood Is All Stones


Chapter 8: Life in the abandoned mine pit

After completing the last micro-scale soldering, Xu Le took off the deep-color protection mask from his face, feeling quite satisfied. Next, he organized all the fully repaired items inside the workshop room following the labels on the items and sorted them neatly into the metal shelf. A push of a button by the shelf sent all the items outside of the workshop room. By early morning next day, these repaired items would be shipped back to the fourth district of the Xiang-Lan Boulevard. Out of old habit, Xu Le always got things ready ahead of time.
He quickly washed his face with hot water, and then smoothly retrieved a bottle of eye solution from a drawer and carefully added a few drops to his eyes. Even with the help of various microscope type instruments, the world of metal chips could still be quite a torture for the eyes of any electrical technician. Especially since he would always forget about time when he devotes himself into the world of metal chips, both of his eyes appeared to have reddened.
“Go get a rest. Enjoy some scenic views and relax the muscles in your eyes.”
Feng Yu rubbed his own gray hair and felt very satisfied with Xu Le’s speed and concentration. For the last half a year, most of the repair jobs for the electrical appliance repair shop at the Xiang-Lan Boulevard were really completed here by Xu Le in the secluded mine tunnel. And all Feng Yu had to do was to stay at his shop during weekdays and then show up here to give a few pointers during the weekends. As time went by, Xu Le’s repair speed had become faster and faster, now even faster than Feng Yu, who was once an electrical technician in the military.
Xu Le acknowledged with a mumble. He took out two bottles of fruit juice from the freezer and then followed behind Feng Yu, walking toward the upper part of the mine pit.
Xu Le could hear the non-stop clanking sound coming from the front. He couldn’t help but look up, and then once again, he saw the extremely eye-catching ragged jeans worn by Uncle Feng Yu, together with the tightly wrapped buttocks, and also … a bunch of keys, screwdrivers, and the kind of metal things alike. They swung non-stop in the air and again and again hitting the big buttocks, making disturbing noises.
Xu Le could never understand why Feng Yu would present himself in such a way. But Feng Yu told him that it’s just like the sword of a swordsman or the gun of an assassin would never be left behind. Therefore, electrical technicians should never let their tools be left behind…. Xu Le actually knew it. This uncle believed that wearing wind chimes on his ass makes him look extra manly, which could really help him attract the eyes of those young and lonely ladies.
 It was already quite late. The light above the Eastwood Grand District had gradually dimmed. The twilight also gradually turned redder and darker, producing a dazzling shine through the reflections against the large pile of metal thingy behind Feng Yu’s back. Xu Le squinted his eyes naturally and gazed at the shadow that was climbing the slope not at ease. He suddenly remembered the moment two years ago when he foolishly walked in the repair shop.
The relationship between him and Feng Yu was a bit strange. It was not a relationship between student and teacher, but he did learn from Feng Yu knowledge and practical experience about electronics, something he always longed for.
Although repairing electrical appliances didn’t help him at all with respect to his dream, the dream of becoming an auxiliary officer of a battleship or living a better life in the Capital Star Circle, Xu Le did find satisfaction and equilibrium from the small repair shop.
Xu Le was not an employee of Feng Yu, either, because Feng Yu never paid him any money and only left enough food in the freezer. Such treatment would only make Xu Le a pitiful slave of the Xiang-Lan Boulevard Repair Shop … but Xu Le did make quite some bucks for the repair shop during the past two years.
“The registration fee for the draft exam, if I choose electrical technician … the government will only reimburse forty percent.” Staring at the back of the uncle, Xu Le finally gathered enough courage to make his demand. “There are only two years left. I really need to save some money.”
The hidden meaning of these words was of course a request to get paid by the repair shop owner, but Feng Yu rejected it without even looking back.
“It was you who cried and begged me to teach you. Did I ever ask you for any tuition?”
What a shameless guy! Even more shameless than I am! Xu le thought to himself. Then he remembered the time when he first ran into the repair shop and how he shamelessly held onto the owner’s thigh. The courage to ask for money quickly diminished. He heaved a helpless sigh, ran a few steps, and then sat by Feng Yu’s side.
The two of them were now sitting at the very top of the mine pit. Behind them were the shadows of the city’s buildings, which were a good distance away and appeared blurry and unreal. In front of them was a large stretch of green grassland. Deep in the grassland they could see tall trees reaching the sky. The refreshing scene of the nature almost felt like a jumping flame, burning with ardor under the setting sun.
“I’ve always been curious.”
Feng Yu didn’t take the juice Xu Le handed to him, instead, lit another cigarette. He took a deep breath in with a great joy and then glanced greedily at the grassland the forest in front of him before continuing.
“There are at least one thousand repair shops in the Eastwood Grand District. Why did you choose me?”
Xu Le cast a side glance toward him, shocked at the idea that he had only thought of the question after two years had passed. After a short pause, he finally looked down and replied.
“The automatic vacuum door of the coffee shop had stopped working. I heard that you fixed it, so I decided to find you.”
“Anyone could have fixed that door,” Feng Yu exclaimed without turning his head.
“Perhaps you were in a really good mood when you fixed that door….” A slight trace of cunning quickly flashed across Xu Le’s eyes, which always looked extra sincere when he smiled. “The glueless vacuum joint at the B2 port was simply remarkable, with an error grade in the one-thousands. That was two grades higher than the civilian standards, even slightly higher than the military standards. Ever since then, I knew you weren’t just any ordinary guy, boss!”
Feng Yu seemed to have been startled. He suddenly burst into laughter. Turning around he raised his hand as though to strike Xu Le’s head, but eventually he settled for rubbing the untidy black hair.
“You are crazy! Who would have thought of measuring that thing?”
“Maybe it was just my intuition?” Xu Le smiled happily. “I just felt there was something really weird about that door, and I happened to have some money at that time, so I went and bought a multi-spectrometer. And as soon as I measured it, I found the oddity.”
“Even the smallest multi-spectrometer won’t fit under the door. How did you measure it? I am quite curious.” Feng Yu’s interests instantly shot up.
“Hmm….” After a short moment of awkward silence Xu Le finally answered. “I asked for Li Wei’s help, and the two of us took the door apart at night … of course we put it back on the same night. I am no thief.”
Feng Yu couldn’t help but laugh again.
“But didn’t I install an alarm on that door…?” he asked.
“The one hidden inside the double-pane glasses?” Xu Le lowered his head in embarrassment. “I…I found it right away and…took it apart too.”
Feng Yu suddenly fell quiet. He stared at the young lad next to him, and for a long time, didn’t speak another word. Two years ago, Xu Le was only a self-studying student who only knew how to memorize processes and standards from books in the library. Even then Xu Le was already capable of disabling an alarm set up by Feng Yu, himself. Now when he thought about it, the conclusion he had come to earlier on the couch was indeed accurate.
Right at that moment, several majestic-looking wild buffalos, cloaked in the beautiful twilight of the dusk, slowly wandered outside of the woods and walked toward the direction of the mine pit.
Both Xu Le and Feng Yu instantly stopped all thoughts and motion and only stared at the buffalos steadily. The stares were filled with greed.
“Uncle, we haven’t had any fresh buffalo steaks for half-a-year now,” Xu Le swallowed a mouthful of slaver and suggested.
Feng Yu stood up slowly and cast a glance at the long, endless metal isolation guardrail that separated the mine pit and the grassland, his face turning into a grimace.
“All through my life, I hate two federation laws the most. One of them is that god damned Wild Life Protection Act.”
Xu Le tried hard to hold his laughter. Raising his head up, he asked, “What’s the other one?”
“The First Constitution.”
After that most arrogant statement, he led Xu Le toward the wild buffalos on the other side of the isolation guardrail, looking vicious and dangerous.

Robot of the Day: Microswimmer Robot Taking Pictures of Your Intestines

This is a robot I read about recently, a robot the size of a pill that can swim inside your body powered by external MRI machine's magnetic fields with the task of taking pictures of your intestines.

Credit: Tel Aviv University and Brigham & Women's Hospital
The robot was developed by scientists at Tel Aviv University in Israel and Brigham & Woman's Hospital in Boston and introduced in a recent paper published in Biomedical Microdevices. Although still in the early testing stage in a water tank, the tiny robot seems to maneuver well with its 20mm x 5mm tail. The eventual objective of robot is to enable doctors to see the inside of a patient's intestines and detect early stages of gastrointestinal cancer.

Presently doctors can already have patients swallow a pill-sized camera. Pictures are taken every half second or so until the camera is passed. However, doctors have no control of the camera's movement when they wanted pictures of specific part of the body. One challenge with the robot idea is how to power the robot because embedding large power supplies would increase the size of the robot and cause other problems. The beauty of the proposed solution is that it uses magnetic field to control the movement of the robot via the little copper and polymer tail. And since MRI machines are already a common device in hospitals, they can become very handy.

I remember seeing a video of how live bacterias can be controlled by magnetic fields to push around a "nano-robot" in a Discovery Channel documentary. In this case, the magnetic field controls the robot directly which is probably more predictable than trying to control bacterias.

Some people even suggest that we can leave such robots inside us permanently like parasites. Now imagine having a bunch of these things inside your body, constantly posting images or videos online of your internal like those live web cams.... Now you not only have no privacy outside of your body, you don't even have privacy inside your body.... Well, but if lives can be saved, I guess it's okay.

10 Famous Thought Experiments That Just Boggle Your Mind Part 5

Read Part 4: Einstein's Light Beam

6. The Ship of Theseus

One of the oldest of all thought experiments is the paradox known as the Ship of Theseus, which originated in the writings of Plutarch. It describes a ship that remained seaworthy for hundreds of years thanks to constant repairs and replacement parts. As soon as one plank became old and rotted, it would be replaced, and so on until every working part of the ship was no longer original to it. The question is whether this end product is still the same Ship of Theseus, or something completely new and different. If it’s not, at what point did it stop being the same ship? The Philosopher Thomas Hobbes would later take the problem even further: if one were to take all the old parts removed from the Ship of Theseus and build a new ship from them, then which of the two vessels is the real Ship of Theseus? For philosophers, the story of the Ship of Theseus is used as a means of exploring the nature of identity, specifically the question of whether objects are more than just the sum of their parts.


I couldn't help but think of the story about Steve Jobs and his Mercedes Benz. Steve was able to exploit a hole in Californian law and roved the Silicon Valley in a Mercedes without license plates:

It turns out there's a provision in California regulations that give one six months to get license plates for a new car, and Jobs took advantage of it. Yes, he leased a silver Mercedes SL55 AMG, said Callas -- and every six months he traded it in for a new one.
So to Steve, the car was still The Car of Jobs, but to the Californian DMV, the car was a different one.

It might not matter too much if this thing we talk about is just a physical thing like Steve Jobs' car. What if it is an intangible object, for example, a song. If we move up or down the pitch of all notes in the song, is it still the same song? If you think the answer is yes, then what if we move the pitch to a range where human can no longer distinguish them?

Now let's think about robots. US Soldiers in Afghanistan have being using remotely-controlled robots to detonate road-side bombs. As unintelligent as these robots are, many soldiers have developed close affection toward these devices. When damaged robots are sent in for repair, the normal procedure is to simply send back a replacement unit because it is most time-efficient and cost-efficient. However, many soldiers demanded the exact same unit or robotics device to be repaired and sent back because they have assigned a personal identity to the robot as a teammate and friend.

Let's think one step further. With robots that are more intelligent, especially ones that learn from past experience, it is still possible for us to duplicate the programs and memory of the robot (with the exception of Johnny 5) and then load the same programs and memory into an identical robot. Now we run into a real identity crisis -- both for the robots and the users. Both robots will think they are the original robot, and to the user, both robots are the original robots with the same memory, same logic, and same appearance. (Why do I keep thinking of the movie The 6th Day?) What problems will this create?

I also can't help but think of all the protagonists in these reincarnation novels (like the Joy of Life story I am translating, for example). Are these persons still the same persons? Probably not! But why not?

That's enough philosophical discussion for today! Have a good day!

Robot of the Day: CQ-10 Snowgoose Cargo Delivery Glider UAV


CQ-10 Snowgoose is a glider UAV developed by Mist Mobility Integrated Systems Technology (MMIST), a Canadian firm, for the purpose of pinpoint precision small cargo delivery. It is one of the earliest UAVs (Unmanned Aerial Vehicles) used by US military in the war in Afghanistan.

The Snowgoose UAV uses a parafoil for lift and then a "pusher" propeller to help with the glide. A newer version of the UAV CQ-10B actually includes an autogyro rotor for lift and is capable of vertical take off and landing. Therefore the UAV is capable of three types of deployments:
  • ground launching from the back of a truck or Humvee,
  • air launching from the back of a cargo plane,
  • or self launching using the gyro rotor.
The Snowgoose UAV has six modular cargo bays and can be used for leaflet dispensing or delivery of small amount of ammo or medical supplies. The newer model can carry up to 2400 lbs of cargo and travel up to 93 miles. Operator can upload flight plans to the UAV and then the UAV will perform the delivery fully autonomously. This can be very helpful in search and rescue missions, disaster relief efforts, or support military operations in hostile environment.


In 2003, U.S. Special Operations Command bought five of these for $250,000 each and deployed them to Afghanistan in support of special operations in the tough terrains.

With the steep price tag, it is unlikely to see such UAVs used in search and rescue missions (with the exception of this story), which is kind of a shame. That's why cheaper and smaller Micro-UAVs stand better chance of actually deployment in local search and rescue teams.

10 Famous Thought Experiments That Just Boggle Your Mind Part 4

Read Part 3: The Ticking Time Bomb

7. Einstein's Light Beam

According to his book Autobiographical Notes, Albert Einstein’s famous work on special relativity was inspired by a thought experiment he conducted when he was only 16 years old. He thought about chasing a beam of light as it traveled through space, and reasoned that if he were able to move next to it at the speed of light, he should be able to observe the light frozen in space as “an electromagnetic field at rest though spatially oscillating.” For Einstein, this thought experiment proved that for his imaginary observer “everything would have to happen according to the same laws as for an observer who, relative to the Earth, was at rest.”

The video below gives a good example of special relativity.



I can't think of how this relates to AI, but the lesson here is that simple thought experiments can lead to extraordinary findings. Therefore I'll keep running all kinds of thought experiments in my head like how properties of intelligence should remain the same regardless of what species is displaying intelligent behaviors.
