Watch: How Does a Dead Fish Swim Upstream?

Take a quick look at this trout swimming upstream. Notice anything unusual?

You’ve probably seen something similar countless times; the fish wriggles against the currents that push it backwards, slowly making headway until it turns and ducks out of the influence of the stream. Nothing special in that.

The only thing is, this particular fish is dead.

Tesla Autopilot – Update Timeline

Tesla follows a similar format to semantic versioning for organizing software updates. In the version “2020.12.11.1”, 2020 is the year and 12 is the week a specific update began development, 11 is a major update, while 1 is a minor update or maintenance (bug fixes).

What is TRIZ

Imagine the biggest study of human creativity ever conducted. Picture the systematic study of over two million of the world’s most successful patents, and the construction of a problem solving method which then combines those solutions into a whole that strips away all boundaries between different industries. Now imagine that it exists. What you’re seeing is TRIZ. The reason you may not have heard of it before, is that it was initially devised and developed in the former Soviet Union, and practically no-one outside the Eastern Bloc had heard of it before the fall of the Berlin Wall. In this paper, we examine what that Soviet research achieved and how that platform has now been transformed into a comprehensive Systematic Innovation methodology, suitable for all types of innovation and innovation management issues. In the paper we show how today’s version of the method is helping users to systematically and reliably create breakthrough solutions to problems of all descriptions.

Army ants dynamically adjust living bridges in response to a cost–benefit trade-off

The ability of individual animals to create functional structures by joining together is rare and confined to the social insects. Army ants (Eciton) form collective assemblages out of their own bodies to perform a variety of functions that benefit the entire colony. Here we examine ‟bridges” of linked individuals that are constructed to span gaps in the colony’s foraging trail. How these living structures adjust themselves to varied and changing conditions remains poorly understood. Our field experiments show that the ants continuously modify their bridges, such that these structures lengthen, widen, and change position in response to traffic levels and environmental geometry. Ants initiate bridges where their path deviates from their incoming direction and move the bridges over time to create shortcuts over large gaps. The final position of the structure depended on the intensity of the traffic and the extent of path deviation and was influenced by a cost-benefit trade-off at the colony level, where the benefit of increased foraging trail efficiency was balanced by the cost of removing workers from the foraging pool to form the structure. To examine this trade-off, we quantified the geometric relationship between costs and benefits revealed by our experiments. We then constructed a model to determine the bridge location that maximized foraging rate, which qualitatively matched the observed movement of bridges. Our results highlight how animal self-assemblages can be dynamically modified in response to a group-level cost-benefit trade-off, without any individual unit’s having information on global benefits or costs.

Symbiosis in Development Book

This unique first edition hardcover of the Symbiosis in Development framework is the first complete handbook and reference manual from theory to practice on sustainable development and societal transitions.

SiD creates a complete language and backbone structure for all aspects associated with sustainable development. This includes systems thinking, the circular economy, natural capital, climate adaptation, and true value costing. Its method combines design thinking with a practical co-creation methods. SiD’s process tools allow a team to innovate new, groundbreaking solutions from A to Z. It connects a wide range of sustainability approaches, including the circular economy, the blue economy, natural capital, design thinking, the Sustainable Development Goals, co-creation, biomimicry, and Impact Design.

The Reflective Practitioner: How Professionals Think In Action

A leading M.I.T. social scientist and consultant examines five professions—engineering, architecture, management, psychotherapy, and town planning—to show how professionals really go about solving problems.The best professionals, Donald Schön maintains, know more than they can put into words. To meet the challenges of their work, they rely less on formulas learned in graduate school than on the kind of improvisation learned in practice. This unarticulated, largely unexamined process is the subject of Schön’s provocatively original book, an effort to show precisely how ”reflection-in-action” works and how this vital creativity might be fostered in future professionals.

Problem Forming, Problem Finding, and Problem Solving in Design

This meeting [1], representing a convergence of students of design from a range of wholly dissimilar disciplines, is an event of major significance. It is significant that the meeting is being held at all that all of you recognize your common concerns. It is significant that we are gaining deep insights into the design process itself. If it is pretentious to talk about the “science of design,” at least we know now that there are truths about design that can be formulated and communicated, general truths that seem to apply to design as each of us knows it, in his or her particular professional domain.

But perhaps it is not really pretentious to speak of the science of design. There are principles that are widely applicable, and increasingly, we are finding ways of implementing these principles on electronic computers, and thereby securing the powerful assistance of those computers in the process of design. Let’s compromise on “the art and science of design.”

In recent years, the awareness of our communalities, whatever the specific field in which we work, has been hastened by the applications of computers to design: expert systems, computer aided design, artificial intelligence. Because their programs are open to inspection, computers allow us to look at the design process. The program is a tangible, concrete object. And in order to construct programs to design or assist design, we have to try to understand the process. That process is basically the same, whether it is carried out by people or computers, or, as is increasingly the case, by both in collaboration.
