Hasta La Gadget!

Scientific research and technological advancement have gone hand-in-hand since the invention of the wheel. Without research, we lack the knowledge base to advance the state of technology and, without technological advancement we lack the functional base for further scientific exploration. In their new book, The Genesis of Technoscientific Revolutions, Harvard University Professor of Technology and Public Policy, Venkatesh Narayanamurti, and Sandia National Laboratories Senior Scientist, Jeffrey Y. Tsao, explore the symbiotic relationship between these two concepts and how their interaction might be modulated to better serve the rapidly accelerating pace of 21st century technoscientific discovery.

The Network Is Hierarchical: The Nesting of Questions and Answers

The way in which scientific and technological knowledge are hierarchical stems from the nesting discussed in the last chapter, both of scientific facts and explanations and of technological functions and the forms that fulfill them.

Harvard University Press

In science, at the top of the hierarchy are facts — raw patterns in observed phenomena. These patterns can be thought of as questions: Why does a particular pattern occur? Why when one releases a ball does the ball fall and fall faster the farther it has fallen? Explanations of those raw patterns come a level below in the hierarchy, and can be thought of as answers to those questions: Galileo’s sixteenth-century explanation of the observed distance-versus-time pattern was that the velocities of falling balls increase linearly with time. But this answer, or explanation, becomes itself another question: Why do the velocities of falling balls increase linearly with time? This question begs a deeper explanation, a deeper answer: Newton’s explanation was that gravity is a force, that uniform forces cause uniform acceleration, and that uniform acceleration causes linear increases in velocity. Scientific understanding is always incomplete, of course, so there is always a point at which we have no deeper explanation. This in no way detracts from the power of the explanations that do exist: science seeks proximate whys but does not insist on ultimate whys. The general theory of relativity explains Newton’s laws of gravity, even if its own origin is yet to be explained.

In technology, at the top of the hierarchy are human-desired functions. These functions present problems that are solved by forms below them in the hierarchy. Forms fulfill functions, but those forms present new problems that must be solved at successively deeper levels. Shifting from the problem-solution nomenclature to the equivalent question-answer nomenclature, we can say that the iPhone represented a technological question: How do we create an Internet-capable cellular phone with a software-programmable interactive display? A partial answer came in the form of multi touch capacitive surfaces, opening up a significant design space for user interaction when multiple fingers are used simultaneously. But the opaqueness of existing multitouch surfaces itself became a question: How do we make multi touch surfaces transparent so that the display is visible? The multi touch transparent surface display provided an answer.

In other words, science and technology are both organized into hierarchies of question-and-answer pairs, with any question or answer having two “faces.” One face, pointing downward in the hierarchy, represents a question to an answer just below it in the hierarchy. The other face, pointing upward in the hierarchy, represents an answer to a question just above it in the hierarchy. We emphasize that our depiction of questions as “above” answers and answers as “below” questions is arbitrary — it does not signify relative importance or value but is simply intended to be consistent with common usage. In science, an explanation is deeper and more “foundational” than the fact it explains, especially if it generalizes to explanations of many other facts. Special relativity is, in that sense, deeper than the constancy of c because it answers the question of why c is constant; it also answers the question of how much energy is released during nuclear fission and fusion. In technology, forms are deeper and more “foundational” than the functions they fulfill, especially if they have been adapted to fulfill many other functions. The multi touch transparent surface display is more foundational than the iPhone because it not only helps answer the question of how to create the iPhone, but also helps answer the question of how to create human-interactive displays in general. Rubber is more foundational than a bicycle tire because it not only helps answer the question of how to create a bicycle tire, but also helps answer the question of how to create a myriad of other kinds of tires.

The Network Is Modular: Facilitating Exploitation and Exploration

Closely related scientific questions and answers are organized into what we might call scientific domains, which we will refer to as scientific knowledge modules. Closely interacting technological problems and solutions are organized into engineered components, which we will refer to as technological knowledge modules.

Harvard University Press

Closely related scientific questions are often answerable within a scientific knowledge domain, or scientific knowledge module, drawing on multiple subdomains nested within the larger domain. A question related to some electron transport phenomenon in a particular semiconductor structure lies in the broad domain of semiconductor science but the answer might require an integrated understanding of both the subdomain of electron transport physics as well as the subdomain of the materials science of the synthesized structure. The subquestion associated with electron transport physics might require an integrated understanding of the subdomain of electrons in various kinds of structures (bulk materials, heterojunctions, nanostructures, coupled nanostructures) and of the sub-subdomains of interactions of electrons with phonons in those structures. The subquestion associated with the materials science of the synthesized structure might require an understanding of the sub-subdomains of substrates and epitaxy, thin films, or post materials synthesis fabrication. In other words, we can think of scientific knowledge domains as a modular hierarchy, and think of its subdomains as submodules and sub-submodules.

Closely related technological problems, likewise, are often solved by key technological components, or technological knowledge modules, perhaps integrating multiple subcomponents nested within the larger components. An iPhone is a component itself composed of many subcomponents, and each subcomponent is similarly subdivided. We can think of the “problem” of the iPhone as a component that is “solved” by its subcomponents — an enclosure, a display, a printed circuit board, a camera, and input / output ports. We can think of the “problem” of a printed circuit board as a subcomponent that is “solved” by sub-components that include low-power integrated circuit chips. Conversely, an iPhone is also a component that is itself nested in a hierarchy of use functions. An iPhone might be used as a solution to the problem of “running” a text-messaging app; a text-messaging app might be used as a solution to the problem of sending a mass text message to a friend group; the mass text message might be used as a solution to the problem of organizing the friend group into a protest in Times Square; and the protest in Times Square might be part of a solution to the problem of organizing a wider social movement for some human-desired social cause.

One might ask: Why is scientific and technological knowledge modular? They are modular because they are complex adaptive systems — systems sustained by and adapted to their environment by complex internal changes — and virtually all complex adaptive systems are modular (Simon, 1962). Complex adaptive systems both exploit their environments and explore their environments to improve that exploitation. Modularity enables efficiency, both in the exploitation of existing knowledge about the environment and exploration of that environment to create new knowledge.

While Disney+ has had no problem putting out MCU shows this year, there’s still a vocal legion of fans who yearn for the stars of the once mighty Netflix series to get their due. Primarily, this hope has reserved for Charlie Cox’s Daredevil and Jon Bernthal’s Punisher, and while Cox has rather gracefully talked about…

If you’re looking to treat yourself this holiday season, a robot vacuum could be the gift that keeps on giving. We saw a bunch go on sale for Black Friday, but now Wellbots is having a sale on one of Roomba’s most advanced models. The Roomba s9+ is $200 off right now when you use the code ENGADGET200 at checkout, so you’ll end up paying $899 for the machine — that’s the best price we’ve seen it and even cheaper than it was last month during Black Friday and Cyber Monday.

Buy Roomba s9+ at Wellbots – $899

The s9+ is even more advanced than the new Roomba j7+ that came out recently, although it does not have Precision Vision Navigation like the latter. Instead, the S9+ has the most suction power of any Roomba along with dual multi-surface brushes and Direct Detect technology, the latter of which helps the vacuum focus on the dirtiest spots in your home until they’re fully clean. “Power-lift suction” also helps it deep clean carpets and suck up pet hair. It has sensors to help it move around objects like chairs and tablets and, thanks to its mapping technology, you can have it clean only certain rooms or areas of your home if you wish.

This model also has the clean base that comes with other more expensive Roombas. After each job, the s9+ will automatically return to its base for a recharge, and it will empty its bin into the clean base, which is basically an attached garbage can. That means you don’t have to fuss with the vacuum every time you run it, and you’ll only have to empty the clean base once every 60 days. That combined with the robot’s easy-to-use companion app makes it a premium convenience machine — if you use iRobot’s mobile app to start or schedule cleanings, you may not even have to touch the s9+ for weeks at a time while it does its job.

Even on sale, the Roomba s9+ is a big purchase — but it may be worth it for those who hate vacuuming and want their homes to be as clean as possible without having to do much themselves. There are plenty of budget options, though, if you’d rather save a good chunk of money and still get the benefits of a robot vacuum. The Roomba 694 is a good option, as well as the Anker RoboVac 11S. The former can be controlled via a mobile app while the latter comes with a remote that lets you maneuver the vacuum like a toy car in addition to setting schedules and the like.

Mark Zuckerberg is building a metaverse. Jack Dorsey resigned from Twitter and is focused on blockchain and crypto. The Atlantic’s Charlie Warzel argues that two of the biggest figures in online culture focusing their ambitions on “the escape pod” is a sure sign this “iteration of the internet” nears its end. 

‘Magic dirt’: How the internet fueled, and defeated, the pandemic’s weirdest MLM

Brandy Zadrozny, NBC News

A $110 bag of dirt was marketed by Black Oxygen Organics as a way to improve brain function, heart health and rid the body of toxins. It took off as an internet-based multi-level marketing scheme before people started debunking claims of wellness benefits. Turns out, samples exceeded daily limits for lead and arsenic if multiple doses were taken. 

Here’s why movie dialogue has gotten more difficult to understand (and three ways to fix it)

Ben Pearson, Slashfilm

Have you resorted to subtitles to help you follow dialogue in a movie because you can’t hear it clearly? You’re not alone, and it’s not because you’re suffering from hearing loss. There are a number of reasons for low talking, and thankfully, there are also a few ways to give yourself some relief.
