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.
Interaction of Color
The deception of color
In order to use color effectively it is necessary to recognize
that color deceives continually.What counts here – first and last – is not so-called knowledge
of so-called facts, but vision – seeing.Practice before theory
Instead of mechanically applying or merely implying laws and rules
of color harmony, distinct color effects are produced
– through recognition of the interaction of color –
by making, for instance,
2 very different colors look alike, or nearly alike.The aim of such study is to develop – through experience
– by trial and error – an eye for color.
This means, specifically, seeing color action
as well as feeling color relatedness.As a general training it means development of observation and articulation.
This book, therefore, does not follow an academic conception
of “theory and practice.”
It reverses this order and places practice before theory,
which, after all, is the conclusion of practice.50 reds
If one says “Red” (the name of a color)
and there are 50 people listening,
it can be expected that there will be 50 reds in their minds.
And one can be sure that all these reds will be very different.Not the what but the how
Our concern is the interaction of color; that is, seeing
what happens between colors.We are able to hear a single tone.
But we almost never (that is, without special devices) see a single color
unconnected and unrelated to other colors.
Colors present themselves in continuous flux, constantly related to
changing neighbors and changing conditions.As a consequence, this proves for the reading of color
what Kandinsky often demanded for the reading of art:
what counts is not the what but the how.Scotopic seeing
The sensitivity
and consequently the registration of the retina of an eye is different
from the sensitivity and registration of a photographic film.Normally, black-and-white photography registers all lights lighter
and all darks darker than the more adjustable eye perceives them.
The eye also distinguishes better the so-called middle grays,
which in photography are often flattened if not lost.This shows what a higher key in light can lose in photography.
The greatest advantage the eye has over photography
is its scotopic seeing in addition to its photopic seeing.
The former means, briefly, the retinal adjustment to lower light conditions.Disliked colors
We try to recognize our preferences and our aversions –
what colors dominate in our work; what colors, on the other hand,
are rejected, disliked, or of no appeal. Usually a special effort
in using disliked colors ends with our falling in love with them.Color intervals
The tune of “Good morning to you” consists of 4 tones. It can be sung
in a high soprano, a low basso, and in all in-between voices, as well as
on many levels and in many keys. It can be played on innumerable instruments.In all possible ways of performance, this melody will keep its character
and it will be recognized instantly.Why? The intervals of the 4 tones, that is, their acoustical
constellation (again comparable with a topographical relationship),
remains the same.Although it is not common practice, one can also speak of intervals
between colors.
Colors and hues are defined, as are tones in music, by wavelength.Any color (shade or tint) always has 2 decisive characteristics:
color intensity (brightness) and light intensity (lightness).
Therefore, color intervals also have this double-sidedness, this duality.Time and space
Tones appear placed and directed predominantly in time from before to now to later.
Their juxtaposition in a musical composition is perceived
within a prescribed sequence only.
Horizontally, the tones follow each other,
perhaps not in a straight line, but of necessity in a prescribed order
and only in 1 direction – forward.
Tones heard earlier fade, and those farther back disappear, vanish.
We do not hear them backward.Colors appear connected predominantly in space. Therefore,
as constellations they can be seen in any direction and
at any speed. And as they remain, we can return to them repeatedly
and in many ways.
This remaining and not remaining, or vanishing and not vanishing,
shows only 1 essential difference between the fields of tone
and color.The accuracy of perception in one field is matched
by the durability of retention in the other, demonstrating
a curious reversal in visual and auditory memory.A cook with taste
Observe the interior and exterior, the furniture and textile decoration
following such color schemes, as well as commercialized color “suggestions”
for innumerable do-it-yourselves.Our conclusion: we may forget for a while those rules of thumb
of complementaries, whether complete or “split”, and of triads and
tetrads as well.
They are worn out.Second, no mechanical color system is flexible enough
to precalculate the manifold changing factors, as named before,
in a single prescribed recipe.Good painting, good coloring, is comparable to good cooking.
Even a good cooking recipe demands tasting and repeated tasting
while it is being followed.
And the best tasting still depends on a cook with taste.Flexible imagination
By giving up preference for harmony,
we accept dissonance to be as desirable as consonance.Besides a balance through color harmony, which is comparable
to symmetry, there is equilibrium possible between
color tensions, related to a more dynamic asymmetry.Again: knowledge and its application is not our aim;
instead, it is flexible imagination, discovery, invention – taste.Does it have color?
Whether something “has color” or not is as hard to define verbally as are
such questions as “what is music” or “what is musical."The Weber-Fechner law
Exponential increases in physical stimuli produce linear perceptual increases.
Thinking in situations
Naturally, practice is not preceded but followed by theory.
Such study promotes a more lasting teaching and learning
through experience. Its aim is development of creativeness
realized in discovery and invention – the criteria of creativity,
or flexibility, being imagination and fantasy. Altogether
it promotes “thinking in situations,” a new educational concept
unfortunately little known and less cultivated, so far.Not of method but of heart
In the end, teaching is a matter not of method but of heart.
The teacher actually is right and always will gain confidence
when he admits that he does not know, that he cannot decide, and,
as it often is with color, that he is unable to make a choice
or to give advice.Besides, good teaching is more a giving of right questions
than a giving of right answers.Results of a search
This book presents results of a search, not of what is academically called research.
In addition to the dedication of this book, I should like to state that my students in color have taught me more color than have books about color.
Simple forms
The concept that “the simpler the form of a letter the simpler its reading” was an obsession of beginning constructivism. It became something like a dogma, and is still followed by “modernistic” typographers.
This notion has proved to be wrong, because in reading we do not read letters but words, words as a whole, as a “word picture.” Ophthalmology has disclosed that the more the letters are differentiated from each other, the easier is the reading.
Without going into comparisons and the details, it should be realized that words consisting of only capital letters present the most difficult reading—because of their equal height, equal volume, and, with most, their equal width. When comparing serif letters with sans-serif, the latter provide an uneasy reading. The fashionable preference for sans-serif in text shows neither historical nor practical competence.
