Tim: On Building a Z80 Computer

This build will consist of a breadboard, Z80 processor, 8K ROM, 56K RAM, and a display hooked up via VGA. The computer will run Microsoft BASIC. The goal of this project is to get a better understanding of how different parts of computers are connected, get experience with hardware and software work, and create a controller for the robotic arm. The breadboard is essentially the mother board; thus, all of the chips will be attached in their respective places. The computer's memory will only exist as RAM (Random Access Memory) and thus will not be active once the computer is shut off. The OS (Operating System) is stored on the ROM (Read-Only Memory). This allows for the memory chip to be read even after the power has gone out; however, you cannot edit the information on the chip. In other words, it is a read-only chip. Overall, this build will work as a basic computer to control the robot and for the purpose of experimentation.

Marcus, Tim, Winston: Collaborating on Japan

A map of Japan, pictured above.  Image taken from
 topics-on-japan.blogspot.com.
It all began with Marcus.  After spending a year examining game design, and in anticipation of a journey to Spain with a group of peers, he elected to study multiculturalism as his topic.  He declared a plan to examine Japan, Germany, Italy, Brazil, India, and China.  He chose Japan as his first area of focus, and very quickly he learned that he could direct all of his attention towards that one country.  Namely, he wished to learn why anime stems from the country.  He also desired to research Japan's role during World War I and World War II as well as the ideology guiding an emperor's perceived immortality ("Mandate of Heaven").  Feeling motiviated to answer these questions, he was off.

Enter Tim.  He began the year interested in artificial intelligence (A.I.) and quantum computing.  After studying graphene as a sophomore and drones as a junior, he devised a dual topic that could help him answer questions that he has been considering for the past two years:
  • What is the difference between a human and a machine? 
  • How do "smart" machines (drones, A.I.) think and learn relative to humans? 
  • If machines can streamline work and production, can they also manipulate physical reality at the atomic level? 
In order to pursue these inquiries, Tim began watching various science fiction movies such as Ex Machina and Transcendence.  He explored those films as springboards into more complex theories such as machine learning.  Noting that Japan played a role within the world of each movie, intrigued by Japanese roboticist Masahiro Moto's "uncanny valley" theory, and inspired by Haruki Murakami (@harukimurakami_)'s Hard-Boiled Wonderland and The End of the World, Tim came to focus his attention on Japan.  The answers to his questions must lie with that country, he postulated, so he set off to learn the Japanese language.

Then came Winston.  Winston began the year by committing himself to the psychology of horror.  Fascinated by the mechanics of the genre, he labored to differentiate the terms "horror" and "terror."  After listening to 911 calls on YouTube and looking into the synopses of movies such as Tale of Two Sisters, however, Winston came to a realization:  he had progressed down a rabbit hole that no longer accorded to his interests.  A longtime fan and amateur critic of manga, he chose instead to devote himself to anime and Japanese culture.

He did not take long to recognize that Tim and Marcus were pursuing a similar interest.  And so the partnership was born.

Tim and Marcus started to spend significant portions of their time together.  The former created flashcards of Japanese characters and their English definitions, and the latter listened to Japanese language CDs.  They shared their resources so that both could study the language through multiple modalities.  Over time, Tim began to research language acquisition programs such as duolingo as well as tutors that could benefit all three students.  He continued to create flashcards, but his administrative role left Marcus to find a new partner in Winston.  Marcus soon abandoned his CD in order to probe Winston's vast knowledge of Japanese honorifics.  Indeed, having acquired a substantial vocabulary through his reading, Winston frequently tutored Marcus in proper addresses.  In turn, because Marcus often disagreed with Winston's translations, the two conducted spirited debates in which they argued the meaning of certain words.  They then researched one another's arguments, hoping to catch one another in the act of a misinterpretation.

The three boys also conducted (and gradually pooled their resources from) independent explorations.  Marcus, for instance, shared preliminary insights gleaned from painting a flag bearing "The Rising Sun."  He also skimmed the surface of various cultural "artifacts," honing his attention toward The Rape of Nanking and the 100,000 trees planted at the Meiji Shrine. Winston, on the other hand, felt fascinated by the Japanese practice of adult adoptions.  During a particular morning with the Edge faculty, he spent close to an hour situating the disgrace experienced by biological sons relative to the cultural phenomenon of hikikomori (young Japanese men who spend months to years in social isolation within their bedrooms).  Marcus then turned his attention to Japanese pop music, thereby inspiring Winston to explore game shows and commercials that he in turn shared with Tim during a raucous few afternoons.

Truth be told, this partnership will not last forever.  Two of the students are already considering switching their topics away from Japan, so the three spend less and less time together these days.  However, partnerships ebb and flow within the world beyond high school.  By coming together briefly for a time, Marcus, Tim, and Winston experienced the joy, the stagnation, and the bittersweet loss that comes from collaborating successfully.  Indeed, partnerships need not last in order to prove meaningful.  By building a stockpile of resources all their own, the three students developed inquiries par excellence.  They generated understandings of Japanese culture that proved - and continue to prove - far more comprehensive than those that they could have created were they working alone.

- & -

As we wrote within our "Our New Name" post (June 1, 2015), we chose to abandon the name "Independent Project" in favor of Edge for a number of reasons.  One of our more significant motives concerned the nature of "independence" within the program:
As one student pointed out, the IPians do not work "independently."  Yes, they launch individual pursuits that take them in directions that are, in a sense, theirs and theirs alone.  That said, this student went on, the IPians are always collaborating with one another, always learning from and supporting each other as they move forward.  In this way, the community members are very much "dependent."
We in the program could not in good faith maintain our previous name because it would preserve a false philosophy.  It would send a message to those students involved that they must erect silos to keep themselves "independent."  Therefore, we switched names.

Perhaps responding to our decision, Marcus, Tim, and Winston students spent the beginning of this year methodically demolishing their silos.

FINAL: Tim Diversifies His Pursuits

Tim could have chosen to conclude his IP work in April.  Why? After facilitating writing assignments for himself, he discovered a love for the craft and realized that his writing could effect advocacy and change.  He then went about assembling his fellow IPians and developing a comprehensive Keynote for a presentation to Kildonan's Board of Trustees.  This address allowed him to celebrate IP, educate the Kildonan community on the approach, and begin to push for an independent fund for the program.  More importantly, the ensuing conversation offered him a natural scenario in which to practice his public speaking, a skill that he attributes to IP and its varied forums.  To repeat, Tim might have chosen to conclude his year's work with this event.  In so doing, he would have left the year with a strong arc/​portfolio.

But he chose not to do this.  Therefore, he - and his pursuits - proved even stronger at year's end.

Per our article announcing "Edge," Tim chose to spend the remainder of his year expanding upon his learning "process."  This final push saw him begin many smaller projects that will undoubtedly inform his Edge work next year as well as his upcoming college application process.  During the final month and a half or so, Tim explored:

Tim's Blog, "Exploring Current Events"(1) Blogging.  Not long before designing his presentation to the Board of Trustees, Tim worked with his tutor to create a blog "Exploring Current Events" via Blogger.com (@Blogger).  This profile serves a dual purpose.  It allows him, on one hand, to continue to develop his writing skills and to practice strategies such as audience awareness, digital literacy, research, and proofreading.  On the other hand, this blog also encourages him to extend his IP work to the Internet and share his thoughts with a larger community.  Tim has reflected upon topics ranging from the limitations of dyslexia empowerment, Steve Jobs and his approach to business, Greece's request for $300 billion of Germany, and Elon Musk (@elonmusk)'s challenge to utility companies with his "Powerwall."  Please be sure to check out Tim's blog, as he is likely to continue this profile when school resumes in September.

Hard Drive(2) Hard Drive Deconstruction.  During the final month of school, Tim began to dissect a hard drive in order to understand its mechanics.  He felt particularly interested in how an actuator reads the disk in addition to how a hard drive's retrieval system compares to that of a floppy disk.  Tim and the IP faculty enjoyed various conversations on the defragging process and viruses.  Ultimately, Tim proved relentless in analyzing the machine.  He even used his accidents as learning experiences, such as when - after cracking one of the magnets in the hard drive - he began to study neodymium.

A hobbyists's drone(3) Networking.  Early in May, IP received a visitor in the person of Evan Donovan, a Kildonan alumnus ('13) who created a personal IP-esque structure before the program even existed.  While visiting, he and the IP faculty happened to begin speaking about 3D printers.  His college possesses two of the devices, he explained, and he uses them in order to print out the body and parts for drones.  He went on to to say more, and before he made much headway, we called in Tim to participate.  The two students lost track of the IP faculty and held a heady conversation concerning rotor databases and drone designs.  Ultimately, Evan recommended that Tim purchase a $75-$120 practice drone of the hobby variety; such a device, he assured the latter, could help him learn the basics of flight without the cost of a top-notch machine.  He also offered that he and Tim get together over the summer in order to troubleshoot the latter's drone work.  Tim readily agreed.  This evolving partnership bodes well for Tim's work next year (drone specific or otherwise).

Quantum Computing(4) Quantum Physics and Fusion.  Tim gave the IP faculty a pleasant surprise when he approached them one day with the request to explore quantum physics.  He assured us that this branch of his studies would constitute only one week's worth of study, but fortunately, he has immersed himself in this discipline to a depth much greater than he originally expected.  During Founders' Day, for instance, he replicated the "Double-Slit Experiment" (not unlike Khaled) and went on to speak towards theories he was researching.  He felt particularly inspired by quantum computing and quantum entanglement theory for their ability to revolutionize computer effectiveness.  This interest aligned nicely with the in-roads that he forged into Lockheed Martin Skunk Works (@LockheedMartin), a company that is attempting to build a prototype that harnesses the power of fusion for commercial and defense ventures (see the video below).

Thank you, Tim, for continuing to diversify your work as a true polymath! We are proud of your progress and maturation this year, and we encourage our readers to celebrate with us by posting in the comments section below.

IP Meets the Board of Trustees

On Friday, April 17th, the IP community celebrated an unprecedented event.  Four students - Tim, Trey, Khaled, and Bull - organized a presentation for Kildonan's Board of Trustees.  Led by Tim, this panel sought to share their projects and request funding for the program.  Their primary reason for the presentation, however, was to educate.  They wished to discuss schooling more generally and to tout the powerful self-directed learning that occurs within IP.

The presentation was a hit for both students and trustees alike.  Equipped with talking points as well as images of students at-work, the IPians spoke eloquently about IP.  They each shared their stories in the program and disclosed the particular benefits that they continue to reap from the IP community.  The Board, in turn, provided inquiries that launched an engaging Q&​A session.  During this time, the students were able to speak more specifically to the logistics of the program, sharpen their pedagogical comments, and meditate on IP's structure for the 2015-2016 academic year.  Once the meeting broke up, too, the board members convened with individual students to engage in one-on-one discussions that proved enthusiastic and supportive.

Thank you, fellow IPians, for supporting these four students as they designed and executed this presentation.  Thank you, Tim, Trey, Khaled, and Bull, for representing your community members and for facilitating a thought-provoking, professional discussion.  Thank you, Mr. Pendergast, for scheduling IP into the Board's agenda.  Last but not least, thank you, Trustees, for proving a receptive audience and for supporting the program as it looks to the future.

Have something to share? Please post in the comments section below.

Tim: Steve Jobs &​ the Ethics of Technology

Ethics of TechnologyEver the savvy technology expert, Tim continues to research drones and game design.  He has begun to complement these explorations, too, by considering the ethics of technology.  This discipline concerns itself with the ethical (or moral) considerations of implementing technology in our modern age.

Tim possesses opinions that are threefold.  First, he sides with the late Steve Jobs, American entrepreneur, marketer, and inventor as well as the co-founder, chairman, and CEO of Apple Inc.  Jobs differentiates between animals and humans in his Steve Jobs on Bicycle (see below), specifically by citing a study that measures the "efficiency of locomotion" of various animals traveling across a flat plane from Point A to Point B.  In this experiment, researchers concluded that the human cannot measure up as a rival to other animals such as the condor.  However, when the researchers then evaluated a human riding on a bicycle, they compiled data measurements that significantly dwarfed all other organisms previously measured.  After reading this research, Jobs concluded that human beings are essentially tool builders; they compensate for natural/​biological weaknesses with the materials that they create.

But Tim goes on to extend Jobs's thinking into a two-pronged critique our culture.  He argues, on one hand, that militaries may wish to curb innovation for innovation's sake due to the risk of reverse engineering.  If they launch drones without comprehensive research into drone defense, for instance, cultural enemies may seize the equipment and use them for counter-measures.  On the other hand, he argues that humans, although they utilize technology, occasionally do not experiment with this equipment to the best of their ability.  This implicit fear hinders humanity; it retards what otherwise could amount to exponential progress and growth, forcing us instead to repeatedly re-hash the same trying problems.  In this scenario, human risk a vicious circle and a technological gap:  a dissonance between our technological capabilities and the technology that we realize and produce.

What do you think of Tim's reasoning? Do you have feedback or a source that he should explore? Please post in the comments section below.

Tim: The Threat of ISIS

An astute and critical researcher, Tim is currently engaged with various projects.  In addition to learning game design through GameSalad.com and repurposing a car from which to launch a drone with a fellow IP student, he is currently examining drone operation alongside the Islamic State in Iraq and the Levant and Islamic State (otherwise known as ISIS or ISIL).  Tim recognizes that the nature of ISIS - along with virtually any other story addressed by mainstream media - depends (in part) upon the news agency (international or otherwise) that a person decides to consult.  Though he encourages the reader to evaluate any story by consulting a variety of sources (such as the links below), this post will primarily utilize information from CNN.com (@CNN).

ISIS, led by Abu Bakr al-Baghdadi (a.k.a. Al-Khalifah Ibrahim), began as a splinter group within al Qaeda.  Its aim, simply stated, is to "create an Islamic state across Sunni areas of Iraq and Syria."  Tim argues that, in some ways, the organization is already operating as a "nation" by instituting independent police and food-distribution networks over its "constituents."  Over the past year, the group has garnered international attention and alarm by the United States for its gruesome executions (including crucifixions and beheadings) as well as its repeated threats to invade America and "raise [the] black flag over [the] White House."

Having examined the uproar concerning drones, Tim believes that Americans need to turn their attention away from these devices.  They need to cease diverting their attention and focus it, as he believes, upon the true threat:  ISIS.  He asks:  "Who are you scared of? The terrorist organization that crucifies, tortures and decapitates people? Or the drones that protect them from you?"

What do you think? Post a response in the comments section below.
