Modular Building Quotes

The designers who had developed the modular concept of lunar construction never considered just how easy it made stealing an entire building, instead of some of the contents.

Modularity is a clunky word for the elegant idea of big things made from small things. A block of Lego is a small thing, but by assembling more than nine thousand of them, you can build one of the biggest sets Lego makes, a scale model of the Colosseum in Rome. That’s modularity.

As an anology, consider the word structure. In bacteria, the gene is embedded in the genome in precisely that format, structure, with no breaks, stuffers, interpositions, or interruptions. In the human genome, in contrast, the word is interrupted by intermediate stretches of DNA: s...tru...ct...ur...e. The long stretches of DNA marked by the ellipses (...) do not contain any protein-encoding information. When such an interrupted gene is used to generate a message-i.e., when DNA is used to build RNA-the stuffer frragments are excised from the RNA message, and the RNA is stitched together again with the intervening pieces removed: s...tru...ct...ur...e became simplified to structure. Roberts and Sharp later coined a phrase for the process: gene splicing or RNA splicing (since the RNA message of the gene was "spliced" to removed the stuffer fragments). At first, this split structure of genes seemed puzzling: Why would an animal genome waste such long stretches of DNA splitting genes into bits and pieces, only to stitch them back into a continuous message? But the inner logic of split genes soon became evident: by splitting genes into modules, a cell could generate bewildering combinations of messages out of a single gene. The word s...tru...c...t...ur...e can be spliced to yield cure and true and so forth, thereby creating vast numbers of variant messages-called isoforms-out of a single gene. From g...e...n...om...e you can use splicing to generate gene, gnome, and om. And modular genes also had an evolutionary advantage: the individual modules from different genes could be mixed and matched to build entirely new kinds of genes (c...om...e...t). Wally Gilbert, the Harvard geneticist, created a new word for these modules; he called them exons. The inbetween stuffer fragments were termed introns.

Summary of Design Heuristics Here's a summary of major design heuristics: More alarming, the same programmer is quite capable of doing the same task himself in two or three ways, sometimes unconsciously, but quite often simply for a change, or to provide elegant variation. — A. R. Brown W. A. Sampson Find Real-World Objects Form Consistent Abstractions Encapsulate Implementation Details Inherit When Possible Hide Secrets (Information Hiding) Identify Areas Likely to Change Keep Coupling Loose Look for Common Design Patterns The following heuristics are sometimes useful too: Aim for Strong Cohesion Build Hierarchies Formalize Class Contracts Assign Responsibilities Design for Test Avoid Failure Choose Binding Time Consciously Make Central Points of Control Consider Using Brute Force Draw a Diagram Keep Your Design Modular

The Indivo system resolves the Problem of Mutual Accommodation of Interdependent Systems summarized earlier by inserting a layer of virtualization between two interdependent structures. It makes the data open, modular, and conformable, so that the applications using the data can be optimized. By being modular (open source), the data in PHRs are commoditized—it is no longer a strategic asset, nor where money can be made. Instead, profit in the industry will be made by firms that build applications that use the data. Some

In their study, in which they matched similar product pairs from each type of organization, the authors found that the more loosely coupled organizations actually created more modular, less coupled systems, whereas the more tightly focused organization’s software was less modularized.

Instead, infrastructural systems are repaired or rebuilt in modular increments, like steadily working through the replacement of water mains in a neighborhood or fixing potholes every spring. But that continuity has a flip side: it locks us into these ways of doing things. The QWERTY keyboard layout was designed to keep fast typists from jamming the keys on manual typewriters, but it’s still in use on smartphone touchscreens. Decisions made decades or even centuries ago—how we treat wastewater, the use of alternating current instead of direct current for electricity grids, pipelines laid for fossil fuels—all of these shape not just the technologies and systems in use today but those that haven’t yet been built. That continuity means there’s a path dependence—that the kinds of systems we have today depend on the characteristics of the systems that came before—in addition to growth and accumulation, as these systems build on each other. We now live surrounded by technological systems of nearly unimaginable scale, extent, and complexity.

So long as module improvement respects the protocols by which the module connects to other modules, module improvement can proceed independently of those other modules. An extreme case of this is when the protocols are between different levels of the modular hierarchy and when there is richness on both sides of the protocol. When the upper side of the protocol is rich, the knowledge base on the lower side of the protocol is often referred to as a 'platform' on which knowledge modules above it can be based. In science, Newton's laws were a platform on which both celestial and terrestrial mechanics could be based. In technology, the personal computer software operating system is a platform on which a rich set of software application can be based. Moreover, when the lower side of the protocol is also rich, the shape of the knowledge network becomes hourglass-like. In the case of technological knowledge, the waist of the hourglass is a distinguished layer or protocol, with technologies underneath implementing the protocol and technologies above building on the protocol - with both sides 'screened' from each other by the protocol itself. As a result, the number of applications explodes independent of implementation details; similarly, the number of implementations explodes independent of application details. The number of software applications built on the Windows operating system is enormous; the number of hardware and software implementations of the Windows operating system is also enormous. In other words, imagine two complex adaptive systems, one organized modularly and one not. At one moment, both might be able to exploit their environments equally and thus be equally 'adapted' to their environment. But they will evolve at vastly different rates, with the one organized modularly quickly outstripping the one not so organized. Modularity appears to be an evolved property in biology, one that is mimicked in the organization of human knowledge.

To become experts at managing complexity, we need the following: Modularity Cohesion Separation of Concerns Abstraction Loose Coupling

Get a small thing, a basic building block. Combine it with another and another until you have what you need. That’s how a single solar cell becomes a solar panel, which becomes a solar array, which becomes a massive megawatt-churning solar farm. Modularity delivers faster, cheaper, and better, making it valuable for all project types and sizes. But for building at a truly huge scale—the scale that transforms cities, countries, even the world—modularity is not just valuable, it’s indispensable.

Yet over the last fifty years or so, asymmetry has crept into our homes and buildings. Architectural critic Kate Wagner traces this shift to the suburban building boom of the blingy 1980s. While the energy crisis of the seventies kept home sizes modest, the Reagan years brought large incentives for the construction industry and a culture of conspicuous consumption that turned houses into status symbols. These luxury homes, dubbed “McMansions,” swelled to include all kinds of new features: exercise rooms, home theaters, three-car garages, and grand oversize entryways. Eager to please, developers sacrificed symmetry for scale, producing massive homes that often felt surprisingly awkward. They sometimes looped architects out of the equation entirely, using a modular approach that allowed prospective homeowners to customize their design based on a kit of options. These options included architectural details like arches, moldings, and bay windows, which were then applied haphazardly to the surface rather than integrated into the structure.
