evermore, and other beautiful things
An Article by Linus the SephistIf all evidence of civilization on Earth was destroyed, and humans had to re-build society from the ground up, what would be different? Feynman reckons that pivotal scientific moments, like the discovery of the atom, will still happen in the same way. Perhaps mathematics will be similarly rediscovered.
Someone told me once in response to this question, no artwork would ever be recreated. The art we create – music, stories, dance, film – isn’t a fundamental element of the universe, or even of humanity. It’s unique to each artist. If you choose to create art, you leave something in the world that has never had a chance to exist before, and will never again have a chance to exist. There will never be another Beatles or Studio Ghibli or Picasso. Art, in its infinite variations of originality, is cosmically unique in a way the sciences will never be. Art immortalizes human experiences that would otherwise vanish in time.
Reality is Very Weird and You Need to be Prepared for That
An EssayWe might be closer than we think to cures for depression, hypertension, and yes, even obesity.
The answer to scurvy was just one thing, plus a few wrinkles — mostly “not all citrus has the antiscorbutic property” and “most animals can’t get scurvy”. This was only difficult because people weren’t prepared to deal with basic wrinkles, but we can do better by learning from their mistakes.
This means don’t give up easily. It suggests that there is lots of low-hanging fruit, because even simple explanations are easily missed.
Lots of theories have been tried, and lots of them have been given up because of something that looks like contradictory evidence. But the evidence might not actually be a contradiction — the real explanation might just be slightly more complicated than people realized. Go back and revisit scientific near-misses, maybe there’s a wrinkle they didn’t know how to iron out.
Tortured phrases
An Article by Holly ElseIn April 2021, a series of strange phrases in journal articles piqued the interest of a group of computer scientists. The researchers could not understand why researchers would use the terms ‘counterfeit consciousness’, ‘profound neural organization’ and ‘colossal information’ in place of the more widely recognized terms ‘artificial intelligence’, ‘deep neural network’ and ‘big data’.
Further investigation revealed that these strange terms — which they dub “tortured phrases” — are probably the result of automated translation or software that attempts to disguise plagiarism. And they seem to be rife in computer-science papers.
Why Most Published Research Findings Are False
A Research Paper by John P.A. IoannidisThere is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance.
A hypothesis is a liability
A Research Paper by Itai Yanai & Martin LercherThere is a hidden cost to having a hypothesis. It arises from the relationship between night science and day science, the two very distinct modes of activity in which scientific ideas are generated and tested, respectively [1, 2]. With a hypothesis in hand, the impressive strengths of day science are unleashed, guiding us in designing tests, estimating parameters, and throwing out the hypothesis if it fails the tests. But when we analyze the results of an experiment, our mental focus on a specific hypothesis can prevent us from exploring other aspects of the data, effectively blinding us to new ideas.
Design Thinking
Ducks and decorated sheds
A duck is a building whose confirmation is a complete symbol or icon. A decorated shed is a building to which symbols, often commonplace signs, have been attached.
Clinging to ideas
Another aspect of design thinking that was evident in the foregoing case studies is the tenacity with which designers will cling to major design ideas and themes in the face of what at times might seem insurmountable odds. Often the concept the designer has in mind can only come to fruition if a large number of apparently countervailing conditions can be surmounted.
Even when severe problems are encountered, a considerable effort is made to make the initial idea work, rather than to stand back and adopt a fresh point of departure.
A concept of style
It is a concept based not on the classification of various physical features of architecture and urban design but on the problem-solving process itself. We have seen that the final outcome of a design process is strongly determined by at least three aspects of that process:
- the subject matter of the organizing principles which are adopted,
- the manner in which these principles are interpreted and reinterpreted in the context of the problem at hand, and
- the sequent of applying such organizing principles.
Consistency in style among the output of designers can thus be understood as a habitual way of doing things, of solving problems.
Form and figure
Form applies to “a configuration with natural meaning or none at all,” whereas figure applies to “a configuration whose meaning is given by culture."
Design skirmishes
it is apparent that the unfolding of the design process assumed a distinctly episodic structure, which we might characterize as a series of related skirmishes with various aspects of the problem at hand.
As the scope of the problem became more determined and finite for the designer, the episodic character of the process seems to have become less pronounced. During this period a systematic working out of issues and conditions took hold within the framework that had been established. This phenomenon is not at all surprising when we consider the fundamental difference between moments of problem solving when matters are poorly defined and those with clarity and sufficiency of structure.
Within the episodic structure of the process, the problem, as perceived by the designer, tends to fluctuate from being rather nebulous to being more specific and well-defined. Furthermore, moments of "blinding" followed by periods of backtracking take place, where blinding refers to conditions in which obvious connections between various considerations of importance go unrecognized by a designer.
Such plans were deemed efficient
The terrain of cities was subdivided along the lines of distinct and discrete patterns of use, with very little opportunity for mixing (separation and concentration of functions). After all, the home environment should be just that…while places of work should be aggregated and serviced with their appropriate supporting functions.
Such plans were deemed efficient.
Constrained by the medium
The inevitable reciprocation that occurs between the act of drawing and the thinking associated with it. The hand moves, the mind becomes engaged, and vice versa. We might ask: How much does the medium of expression actually constrain a design process?
A medium has a way of constraining our choices, and this influence may not involve conscious choice at all. The planner, in the end, sees and understands only those things for which they can provide expression.
Autonomous constraints
Autonomous or independent constraints do not derive from the problem as given and understood…there was nothing in the problem statement, or brief, that required any reference be made to it. This constraint, introduced by the designers, usefully transcended the givens of the problem situation.
Unless the entire problem at hand can be solved using strictly problem-oriented constraints, we have to step outside the known problem context in order to continue problem solving activity.
The strange familiar and the familiar strange
The problem solver, when confronted with a new and yet unsolved problem, overlays the structure of the unsolved problem with an apparently similar problem with which he or she is experienced.
Making the strange familiar and the familiar strange are also principally based on the use of analogy.
