A List of Chinese Inventions

It’s a shame that so few people in the West realize the innumerable contributions that Chinese civilization has made to humanity. It’s astounding how far ahead the Chinese were in just about every area of knowledge. Note that each of these were independently developed by the Chinese, even if some were also used or invented elsewhere.

Finnish Students Don’t Do Homework Or Take Tests

I’ve spoken at length about Finland’s education system before (here, here, and here) and I believe it deserves all the attention it can get, especially since much of this success is due to policies that are applicable in the US (if not elsewhere) — professionalizing the teaching industry, promoting smaller class sizes in conjunction with more student-to-teacher interaction, and so on. I think the following image breaks it down rather nicely, but if you want more information and sources, visit the hyperlinks above.

Happy Birthday Ada Lovelace.

Happy birthday to Ada Lovelace, born Augusta Ada Byron in the UK in 1815, and by some accounts the world’s first computer programmer – before computers even existed.

Ada Lovelace, the only legitimate child of the famous poet Lord Byron, was a mathematician and writer chiefly known for her work on the Analytical Engine, an early mechanical computer developed by Charles Babbage. She helped developed what is considered to be the first algorithm designed to be processed by a machine – what we would today call a computer program.

She even foresaw the potential of computers to perform tasks beyond mere number crunching, centuries before modern computers were developed. While her contributions are contested, she’s still quite an interesting historical character. Do take the chance to read up on her – there’s a great Google Doodle in her honor.

Also, on this day in 1901, the first Nobel Prizes were awarded in the fields of physics, chemistry, physiology or medicine, literature, and peace. Prizes were presented by the king of Sweden, in accordance with the will of inventor Swedish inventor Alfred Nobel. Hat tip to Stepehen Thomas for the reminder.

On This Day…

On this day, November 29, in 1972, American video game company Atari released Pong, one of the first video games to achieve great popularity at both arcades and households. Who would’ve known then what this simple game would eventually lead to (indeed, the American video game industry, including Atari, suffered a devastating crash in 1983).

The humble beginning of what is now one of the world’s largest industries. Who would’ve thought?

 

Oh, and it’s also Liberation Day in Albania, in which the country was liberated from Axis forces in 1944, almost entirely by its domestic resistance movement. Aside from managing to free themselves (thus being one of only two states in Eastern Europe to lie outside the Soviet yoke), Albanians fiercely protected their Jews. The country was perhaps the only one that ended up having *more* Jews after World War II then less.

 

Mother Albania, a concrete statue located at the National Martyrs Cemetery of Albania, honors the nearly 30,000 partisans that died resisting the Axis. The plaque reads: “Glory to the martyrs of the fatherland forever.”

Death in the Age of Social Media

Social media has made the ritual of death pretty interesting. When we die, we will be among the first generation to leave behind a unique timeline of our lives, in the form of photos, biographical information, status updates, and interactions with others. Our profiles will become shrines for our loved ones to leave condolences or see a time capsule of our time on this Earth (I’ve already seen this happen with the Facebook profiles of several deceased friends and acquaintances).

Of course, this would raise another interesting thought: do we plan on keeping our social media profiles indefinitely? Will there be a point where we’ll just grow out of it, or will it continue to mature with us until we die? It’s strange to think that we’ll have this constant (albeit wildly variable) record of our lives following us as we age.

Happy 100th Birthday Alan Turing (Edit: In 2 Days!!)

A man provided with paper, pencil, and rubber, and subject to strict discipline, is in effect a universal machine.

Alan Turing was a visionary mathematician and computer scientist who helped cracked Germany’s military code during World War II, and who developed algorithms and concepts that would eventually lead to the creation of the modern computer. Indeed, he regarded as the father of computer and artificial intelligence, and the “Turing test” is used to this day for determining a machine’s intelligence.

Unfortunately, Turing was also subject to persecution for his homosexuality, which during his time was a crime in the UK. He was subject to chemical castration, public humiliation, and stripped of his job with the UK’s intelligence agency (where he had pioneered a lot of computer and cryptanalytical work).  He died two years later from cyanide poisoning, in what is widely considered to have been a suicide (the government has since offered a posthumous apology for the legal actions levied against him).

It’s a shame Turing would die so relatively young, given what more he could’ve provided us. In his brief time on this Earth, he made  instrumental contributions to what is now one of the most important technological developments in human history. Despite his tragic and untimely death, he left quite a legacy.

Reflections on Obtaining a Smart Phone

So I’ve finally obtained a smart phone of my own, complete with unlimited 4G access (I was due for an upgrade, so it was thankfully affordable). This gadget is a news junkie’s dream: I now have instantaneous access to all the events of the world at all times. I can look up anything and everything whenever a random thought or question comes into my mind. I have a constant stream of knowledge available wherever I go.

Of course, like most innovations, this one is a double-edged sword. It’s nice to have all this information literally in the palm of my hand. But will my often distracting obsession with data and news be made worse by this newfound capacity to expand on it? Sure, I don’t plan on playing any of the games that often distract many of my peers: all my apps are strictly functional (so far). But a distraction is a distraction…how intrusive will this remarkable device be?

I suppose this will offer a wonderful opportunity to test my willpower – or to learn by experience just how difficult it is for the human mind to adjust in this era of constant stimulus. I already know the feeling of data overload firsthand, as I’m sure most of us well-connected youth do. Have I just upped the ante here? I’ll see with time, but for now I’m thoroughly enjoying having so much to read and learn whenever I’m stuck waiting somewhere. For better or for worse, boredom is a thing of the past (though I’ve always carried reading material with me wherever I go, so keeping myself entertained has never been an issue; now I get to save on space).

Another profound thought struck me as I started reaping the benefits of my new toy: that in the palm of my hand, in this lightweight and sleek machine, lies access to almost the entire sum of human knowledge. Anything and everything I could ever want to know – from the mundane, to the profound, from the practical to the philosophical – was available to me almost instantaneously with a few strokes of my fingers. Not a single reportable event in the world can go unnoticed. No conceivable question could go unaddressed. All of that lies within something smaller than my hand, which I can take with me anywhere I wanted.

For most of our history, the majority of our species couldn’t even read or write, let alone have access to the world’s knowledge. We barely knew what went on beyond our little villages. Suddenly, a growing number of us are connected to this immaterial repository of human knowledge known as the internet, and now, if we so choose, we can delve into the near-totality of collected human knowledge.

As I mentioned before, there is certainly a catch as far as the social and psychological effects of all that data – the human mind was never meant to absorb so much information so regularly. We’ll probably come to adapt to it as we have to so many other developments, but it may be a difficult process nonetheless. Who knows? Whatever the caveats, we shouldn’t underestimate how marvelous it is to live in a time when knowledge is no longer (entirely) the domain of the rich and powerful. The accessibility and affordability of these things is getting better with time. Whatever the impact, it’s sure to be weighty.

 

Are Fears of Information Overload Overblown?

Nowadays, it seems that the only thing more ubiquitous than information is the subsequent anxiety about whether the human mind can handle it all. From casual conversations to numerous scholarly articles, debate on the subject is hard to miss. I’ve discussed myself before, reaching an ambivalent conclusion (as I’m wont to do – it’s a bad habit, I know).

Unsurprisingly, I’m not alone in this experience, as BBC columnist ____ shared similar reflections about whether all this concern is merited. He begins by putting some well-needed historical perspective:

A 1971 essay in The Futurist magazine opened with some alarming numbers. The average city, it said, now had six television channels. But, the author warned, there was already one city planning 42 channels and in the future, there could even be places that support 80, 100 or 200 channels. Where will it end, the essay asked.

Just four decades on, in a world of instant-on, hyper-connected reality, the numbers sounds almost laughable. But, it seems, every generation believes that it has reached information overload. Look back through history, and whether it was the arrival of the book or the arrival of the internet, everyone from scholarly monks to rambunctious politicians are willing to pronounce that we can take no more; humanity has reached its capacity. Television, radio, apps, e-books, the internet – it is causing so much anxiety and stress in our lives that we no longer have control. The machines have won.

Or have they?

Every generation invariably fears the changes that emerge within its lifetime, and why not? Change is scary and, by definition, unfamiliar. We don’t know what to expect, even while it transpires before us, so we start debating the implications, the unseen effects, and the long-term consequences.

People once thought that novels would corrupt the minds of the youth or distract them from reality (sound familiar?), or that writing in place of oral traditions would cause a decline in memory. And as the 1970s reference to The Futurist showed, we’ve fretted about technology overloading our minds since before it was even fully utilized. The entire issue was arguably begun, or at least accelerated, by own man in particular:

If we want to understand the modern way we think about so-called “information overload” the best place to start is the 1970 book Future Shock by author and futurist Alvin Toffler. In it, he said future shock is, “the dizzying disorientation brought on by the premature arrival of the future. It may well be the most important disease of tomorrow”.

There is no denying Toffler’s international influence on the way we think about the future. I have seen Future Shock in virtually every used bookstore I have visited from Portland, Oregon to Cartagena, Colombia. With over six million copies sold, it clearly struck a nerve in 1970 and beyond.

Toffler explained in his book that, “just as the body cracks under the strain of environmental overstimulation, the “mind” and its decision processes behave erratically when overloaded.

In a radio interview shortly after the release of his book, Toffler warned that the exhaustion he saw throughout the world was tied to his new future shock theory. “I think there’s a tremendous undercurrent of dissatisfaction in America; people saying I want out, it’s moving too fast, it’s moving away from me; a sense of panic; a sense that things are slipping out of control and I don’t think that there’s much we can do in our personal lives to counteract that,” he said.

Toffler’s assumption was that the future is something that happens to us, rather than with us. It is something out of our control that will inevitably overwhelm us.

Toffler’s statements are almost word-for-word what we hear and read today: the world’s moving too quickly for us to adjust; we’re coming under the mercy of technology forces that we barely understand, let alone control; and all this subsequent anxiety from modernity is making us more depressed, worried, and cynical.

So the psychological strain we’re enduring is just the latter stage of a decades-long process, brought about by a “future” that we didn’t anticipate coming so quickly, and thus couldn’t prepare for. Even the most radical developments – be they technological or otherwise – take generations before their effects are truly felt or learned about.

Whilst some will take comfort in Toffler’s words, some of the notions seem rather quaint forty years later. Just as people today throw around the number of tweets sent per second or the amount of video watched online, in the early 1970s Toffler followers and techno-reactionaries liked to scatter their own figures to show the magnitude of the problem.

In the same Futurist essay that decried the rise of the number of TV channels, the author Ben Bagdikian goes on to overwhelm readers with even more daunting numbers, explaining that computers will soon be able to store information at a rate of 12 million words a minute, whilst printers will be able to pump out 180,000 words a minute; something that will collide violently with humanity’s ability to process information, he said.

“The disparity between the capacity of machines and the capacity of the human nervous system is not a small matter in the future of communications,” he wrote. “It has individual and social consequences that are already causing us problems, and will cause even more in the future.

“The human being of the near future probably will need as much sleep as he does today. He will spend more time absorbing abstract information than he does today, continuing the trend of past generations. But there is a limit.

It is a warning that we still hear today in many contexts. For example, author Jonathan Franzen, an opponent of electronic books, argues that traditional paper tomes give humanity some much needed stability in a world rocked by change. He fears that this rapid pace is hurting us. “Seriously, the world is changing so quickly that if you had any more than 80 years of change I don’t see how you could stand it psychologically,” he said.

Are we really any more stressed out or overwhelmed in the present day then we’ve been in the past? Hasn’t every society of every generation had something to fret about? I’m curious at what point had the world experienced changes that didn’t cause some sort of disruption to the status quo (as changes, by their nature, invariably do). Either we deal with the scary and disorderly unknowns of change, or we wallow in the familiar misery of stagnation.

To be fair, I don’t think Franzen, Bagdikian, or their contemporaries are opposed to change in principle. Their argument seems to be that a certain kind of change, and/or a certain speed of change, is what is unfavorable. That may be a fair point, but what exactly is the solution? Changes of any sort are rarely organized, deliberate affairs – they come about from a random assortment of various dynamics and circumstances. Even people that invent new things or come up with new ideas don’t always the intent, or the means, to see them through, nor can they ever really anticipate what may come of their creation.

In the end, all any of us can do is adapt. Human society will always be too complex, diverse, and disorderly to predict its development or chart an organized course through future obstacles. ____ seems to agree:

Yet history seems to suggest we ride these waves of change. I am typing this on a 15-hour flight over the Pacific Ocean. In that time, I watched two movies, three TV episodes and read half of a (deadtree) book. No one was forcing me to consume this media, nor even write these words. I made a conscious choice that this is how I wished to spend my time. I would also argue that most people reading an essay about the concept of information overload on the internet have some choice in the matter.

Toffler, Bagidikian and Franzen are not necessarily wrong or even alarmist in their concerns that we should seek to control our own technological destinies. But futility should not win the argument. Your consumption of media is largely within your control. We have a choice in the matter. We can change the channel, turn off the TV, or close the laptop lid. These are our choices, and it is hard to see how any of them are irrational or happening to us rather than with us.

Victor Cohn, in his 1956 book, 1999: Our Hopeful Future might have put it most reasonably. Cohn was a pragmatist and understood that we could not run from the future, but that by embracing change we might do some good: “Reject change, and we will be enslaved by it. Others will accept the worst of it and dictate to us. Accept change, and we may control it.”

Sooner or later, the future catches up with us all. But it need not swallow us whole.

That isn’t to say that we shouldn’t keep debating this issue. The naysayers or alarmists raise decent points that deserve serious consideration. We must never shut out well-founded concerns.

It could very well be that we’ll eventually reach a point in our technological development where we’re negatively altered by the forces we unknowingly unleashed. As I said, change is unpredictable and nebulous, so who’s to say that such alterations to our social, political, and economic fabric can’t morph into something we’ll be unable to adapt to.

Personally, I’m an optimist in this regard. I think every development will have its pros and cons. No element of human progress has ever been devoid of caveats. But given that this will always be the case, it seems that the best – if not only – thing we can do is try to understand the forces at work and adjust ad hoc. It’s not a graceful or sophisticated approach, but such is the nature of human beings. We’re constrained by our cognitive limitations, and can only see so much of the bigger picture for so long. Improvements in technology and methodology are helping us, but they can only get us so far – unless some unanticipated radical change fixes that too!

What are your thoughts?

Are We Getting Dumber?

The New York Times is hosting an online debate on the state of human intelligence in the modern world and whether it will decline or improve in the coming generations. All debaters make interesting points, and the commentary from readers can be just as insightful. I encourage you all to share your views (here or there), or at least reflect upon the arguments made. The fates of this planet and our species are dependent upon are own intellectual and innovative capital.

For the record, I don’t believe we’re devolving intellectually – relative to historical levels, a larger number of people are more knowledgeable than ever. It’s just that the standards have changed, and the vast abundance of knowledge – as well as it’s increased availability – raises our expectations for intelligence. I do, however, fear that the growing technological convenience of the modern world may pose a risk to our cognitive development, as it may lead to a disincentive to learn more things or acquire new skills.

Alas, I’m heading to bed, so I can’t expound on my point as much as I’d like. But I will certainly be revisiting this later. As always, I welcome your own input.

Biocapsules: NASA’s Major Medical Breakthrough

For obvious reasons, most people don’t think of NASA when it comes to medical innovation. But the remarkable obstacles that the agency faces regularly – such as keeping human beings alive and well against the punishing conditions of space – make it uniquely equipped for developing game-changing new technologies.

The most recent and promising of these achievements is the NASA Biocapsule, a very humble looking device (see image below) that may revolutionize the way we do medicine back on Earth. Gizmodo, a popular tech site, reports:

Picture this: An astronaut is going to Mars. The round-trip journey will take between two and three years. During that time, the astronaut will not have access to a doctor, and there’s a lot that can go wrong with the human body in space. So, prior to launch, the astronaut is implanted with a number of NASA Biocapsules. A very small incision is made in the astronaut’s skin for each Biocapsule (probably in the thigh), which is implanted subcutaneously. It’s outpatient surgery that requires only local anesthetic and a stitch or two to close the wound. But after it’s complete, the astronaut’s body is equipped to deal with a whole host of problems on its own.
 
One of the primary threats in space is exposure to high levels of radiation. When astronauts travel beyond Low Earth Orbit (i.e., to the Moon or Mars), they are at risk of acute radiation exposure from “solar particle events,” sudden releases of intense radiation from the sun, which can damage bone marrow and wipe out someone’s immune system. That’s where the NASA Biocapsule kicks in: It could be filled with cells that sense the increased levels of radiation and automatically disperse medicine to help the body compensate.
 
This isn’t science fiction. We already use a hormone called G-CSF (Granulocyte colony-stimulating factor) to treat cancer patients who are receiving radiation treatment. So it was a very small jump to put these cells in a capsule. Without G-CSF, an astronaut’s immune system might not recover; he or she could die of a massive infection.
So before jumping the gun on its Earthly applications, we should recognize that this incredible Biocapsule will make long-term space travel more feasible than ever before.
 
One of the biggest and most persistent challenges to manned space exploration has been to ensure the safety and well-being of the astronauts. Not only are their deaths or injuries obviously tragic in their own right, but they tend to fatally erode enthusiasm for space flight and funding. Now we’ll have a better chance of protecting our astronauts, voyaging to further destinations, and keeping the public at ease.
The Biocapsules aren’t one-shot deals. Each capsule could be capable of delivering many metred doses over a period of years. There is no “shelf-life” to the Biocapsules. They are extremely resilient, and there is currently no known enzyme that can break down their nanostructures. And because the nanostructures are inert, they are extremely well-tolerated by the body. The capsules’ porous natures allow medication to pass through their walls, but the nanostructures are strong enough to keep the cells in one place. Once all of the cells are expended, the Biocapsule stays in the body, stable and unnoticed, until it is eventually removed by a doctor back on Earth.
 
While the treatment of radiation-effects in space is NASA’s no. 1 application for the Biocapsule, different capsules will be created to combat different threats. Heat, exhaustion, and sleep-deprivation are serious risks on an EVA (a “spacewalk”), and astronauts are usually on a very tight schedule. Different capsules can be created that contain unique triggers and treatments for different stress-factors. Naturally, DARPA has expressed a huge interest in the Biocapsules for potential military applications. But there are far loftier things planned for us Earthlings.
I know it’s a cliché response, but this really is something out of science fiction. Imagine a tiny, barely noticeable device within your body that protects you from almost any conceivable threat, that does not expire, and that can work for several years before being easily replaced by minor outpatient surgery. It’s incredible that something like this hasn’t gotten more attention yet.
 
Now on to the medical applications I was getting excited about:
The capsule would contain pancreatic islet cells (from animals) or would contain engineered cells designed to behave like pancreatic islet cells, with both glucose-sensing and insulin secretion function. Patients with low-insulin requirement might benefit from implantation of a single capsule (containing perhaps a million to 10 million cells); patients with higher insulin requirement might require implantation of more than one capsule.
 
In other words, diabetes patients might never need to give themselves another shot. They wouldn’t have to worry about remembering to bring medicine everywhere, and they might even be free of having to constantly monitor their blood-sugar levels. Plus, many diabetes patients lapse into comas or die during sleep because that’s eight hours every day when they can’t monitor their levels. The NASA Biocapsules would work automatically, regardless of whether you’re awake or not. As of 2010 there were an estimated 285 million people living with diabetes, so saying that this invention could potentially save millions of lives is not an exaggeration.
But wait, there’s more:
Secondary “terrestrial” applications include cancer treatment (especially brain cancer). A Biocapsule implanted directly into a tumor bed could deliver very high doses of chemotherapy right to the area where it is needed—and it would greatly reduce side effects by minimizing the amount of medication that gets to other sites in the body. There are also important applications in gene therapy.
 
Some children are born missing a gene, or are born with a defective gene. As a result, they can’t make a needed protein. Hemophilia is a classic example. These patients are missing an important blood coagulation protein. The biocapsule could be used to implant cells that are engineered to release the missing protein. Successful therapy would mean that the patients are spared the need to receive periodic injections. Patients would be safely protected by the protein released from the capsule, and they would be able to lead more normal lives.
 
During our visit, we asked Dr. Loftus if there could be applications for severe allergy sufferers. Many people have potentially deadly allergies (to bees, to nuts, etc.) that could send them into anaphylactic shock, and they have to carry a shot of epinephrine (an “EpiPen”) in case of exposure. He said that was very much a possibility, and implementing that technology into the biocapsule would be relatively very simple. He even credited us with coming up with the idea, so in the future when you get stung by a bee and don’t die, you’re welcome, from Gizmodo.
So even if the gene therapy that I’ve been touting doesn’t come to fruition, there is still the amazingly versatile Biocapsule, which can easily be customized to address a wide-range of health problems. Science is never satisfied with tackling just one problem, let alone coming up with just one solution. It’s amazing to think that a technology that was developed to meet a very specific need could spillover to benefit the lives of hundreds of millions of people, if not more. In fact, it already seems commercially viable.
Given all of these applications (and there are many more), it’s not a stretch to say that the NASA Biocapsule could change the face of medicine forever. They are inexpensive and (as you can see in the video) extremely easy to create. The vacuum sucks carbon nanotubes into the mold, you slide the capsule off the mold, you fill it with cells, and then you cap it off either using more nanotubes or a protein glue. Easy as pie. They are scheduled to begin animal trials this year and next, and human trials would begin shortly after that. If all goes well we would likely see these implanted in International Space Station astronauts sometime this decade, and while it’s always a wild guess, Dr. Loftus thinks we could realistically see widespread usage on Earth within 10 to 15 years.
You can see the video in the original article or below:
 
 
Keep in mind that this amazing machine came out of the same agency that’s facing austerity and public indifference (albeit mostly directed at the shuttle program and flights into outer space). Imagine what more we could accomplish if most of society was willing to make the investment.
 
I can easily see this apparatus becoming a standard for everyone. Think of what it can do to people ravaged by otherwise treatable diseases in third world countries, or for the impoverished and elderly in our society. Of course, inventing such solutions tend to be the easy part – developing the ethical, economic, and political means to ensure they actually go to the people that need them is a different story.
 
Still, as far as most innovations go, this one seems to have few noticeable caveats so far. Obviously, we’ll have to wait and see how the coming trials work out. But as always, I’m very excited to see a world where millions of people will live longer and happier lives thanks to the persistence and potency of the human mind.
 
To learn more about the Biocapsule’s incredible inventor, Dr. David Loftus, click here for his contact info. Needless to say, this man and his collaborators must be extremely proud of what they’ve done. I can imagine no greater feeling than learning that you may have just saved the lives of hundreds of millions of people. It’s an achievement few people could ever reach.
