Brushing the Past (2000)

HERE is a superb volume, Brushing the past : later Chinese calligraphy from the gift of Robert Hatfield Ellsworth  by Joseph Chang, Thomas Lawton and Stephen D. Allee. This is the catalogue from an exhibition held at the Freer Gallery of Art, Washington, D.C., Apr. 30, 2000-Jan. 2, 2001.

Below is a close up of a single character from a Qing dynasty couplet in running script by Jian Ren (1743-1795). The original calligraphy is on a pair of hanging scrolls in ink on gold flecked paper.

The full couplet that this character is taken from reads:

Ten meters around, dragon bamboo stands taller than the trees,
In five colors each, sacred mushrooms blossom as big as a fist.

Carcinogenesis

About 25 years ago, I was lucky enough to read in proof copy a book by the cancer biologists Anna Soto and Carlos Sonnenschein called The Society of Cells. In this book, the authors outlined a theory of carcinogenesis (Tissue Organisation Field Theory - TOFT) that was antithetical to the very commonly adopted theory of carcinogenesis known as the Somatic Mutation Theory.  As a neutral (and ignorant) non-biologist it looked to me that the evidence that Sonnenschein and Soto presented supported their theory and that it had some features that made it more attractive than the then dominant one.

Every now and then I try and find out what happened to TOFT and how it is faring against the Somatic Mutation Theory. One of the things that strikes me is that in a field as hellishly complex as cancer biology it is highly unlikely that a full understanding will emerge quickly. If we take as a yardstick the development of physics, from the publication of Newton's Principia in 1687 to the recent and outstanding example of a theory led observational study such as LIGO (Laser Interferometer Gravitational-Wave Observatory), we see 350 years of development of a science by a huge number of incredibly clever people. I assume that we might reasonably expect a full elucidation of cancer to take at least as long. This estimate is a balance of two factors. We would expect that understanding cancer should be quicker due to the application of modern measurement and computing technology. But we should also expect it to be slower because biology does not enjoy the incomparable advantage that physics has of being built on a small number of mathematically tractable and universal laws. 

To help others who are as ignorant of biology as me HERE is a thought provoking personal piece by Prof Robert Weinberg in the journal Cell that describes a story of nearly a hundred years of cancer research. The abstract reads:
Cell has celebrated the powers of reductionist molecular biology and its major successes for four decades. Those who have participated in cancer research during this period have witnessed wild fluctuations from times where endless inexplicable phenomenology reigned supreme to periods of reductionist triumphalism and, in recent years, to a move back to confronting the endless complexity of this disease. 
This paper describes some of the recent history of how cancer research developed, particularly in the US, and a number of frank admissions about current difficulties that mainstream cancer research faces. These lead me to suppose that a full and robust understanding of how cancer develops (to the same level of rigour of LIGO) is still quite some decades away (Weinberg uses the word endless twice in his abstract)  - for example: 
The data that we now generate overwhelm our abilities of interpretation, and the attempts of the new discipline of ‘‘systems biology’’ to address this shortfall have to date produced few insights into cancer biology beyond those revealed by simple, home-grown intuition. The coupling between observational data and biological insight is frayed if not broken.

We lack the conceptual paradigms and computational strategies for dealing with this complexity. And equally painful, we don’t know how to integrate individual data sets, such as those deriving from cancer genome analyses, with other, equally important data sets, such as proteomics. This is most frustrating, since it is becoming increasingly apparent that a precise and truly useful understanding of the behavior of individual cancer cells and the tumors that they form will only come once we are able to integrate and then distill these data.
For what it is worth, and I freely admit it is worth next to nothing, my money is on Soto and Sonnenschein's Tissue Organisation Field Theory of carcinogenesis - if only because they begin their explanation of cancer with the complexity of real tissues, rather than with an extreme form of probably misplaced reductionism. 





 




 

Aristotle to Zoos (1985)

Scientists who seek to explain their specialised area of knowledge to a wider audience run the risk of either dumbing down their exposition or peppering their prose with unexplained and arcane technical jargon. One outstanding example of a world class scientist who was able to explain his area of science in a pithy and engaging prose style was the brilliant Nobel prize winner Sir Peter Medawar (1915-1987).

My favourite example of Medawar's superb writing is his `philosophical dictionary of biology',  Aristotle to Zoos, which he co-authored with his wife Jean Medawar. Below is part of the entry on Hypothesis and Theory.

Hockney-Falco Thesis (2000)

HERE is a superb and up to date site describing the development of, and evidence for, the Hockney-Falco thesis propounded by David Hockney and Charles Falco.
The Hockney-Falco Thesis: Our thesis is that certain elements in certain paintings made as early as c 1430 were produced as a result of the artist using either concave mirrors or refractive lenses to project the images of objects illuminated by sunlight onto his board/canvas. The artist then traced some portions of the projected images, made sufficient marks to capture only the optical perspective of other portions, and altered or completely ignored yet other portions where the projections did not suit his artistic vision. As a result, these paintings are composites containing elements that are "eyeballed" along with ones that are "optics-based." Further, starting at the same time, the unique look of the projected image began to exert a strong influence on the appearance of other works even where optical projections had not been directly used as an aid. 
Below is a close-up from The Arnolfini Wedding by Jan van Eyck, painted in 1434. The detailed fore-shortening, shadowing and reflection of light captured in this image of a chandelier are all typical of an image that has been obtained via optical projection (probably with a concave mirror).



Travels with a donkey in the Cévennes (1888)

For my part, I travel not to go anywhere, but to go. I travel for travel's sake. The great affair is to move; to feel the needs and hitches of our life more clearly; to come down off this feather-bed of civilization, and find the globe granite underfoot and strewn with cutting flints. Alas, as we get up in life, and are more preoccupied with our affairs, even a holiday is a thing that must be worked for. To hold a pack upon a pack-saddle against a gale out of the freezing north is no high industry, but it is one that serves to occupy and compose the mind. And when the present is so exacting who can annoy himself about the future?

The Open Door (1844)

Below is The Open Door by William Henry Fox Talbot from his book The Pencil of Nature. It is a classic Camera image. An image created by, or similar to, an optical projection seen within a camera - either captured by an artist within a camera obscura or captured chemically or electronically in a modern camera. These images have some typical features; often highly detailed, captured from a monocular position, frozen in time as if by a shutter mechanism, obey or approximate the laws of perspective, include shadowing due to strong directional lighting and foreshortening.

Little White Bugs in a Shaft of Sunlight (2016)

In the early years of the 20th century, whilst working on Maxwell's equations and Einstein's theory of special relativity, the Polish-German mathematician Hermann Minkowski (1864-1909) found that it was necessary to meld together three Euclidian dimensions of space and one dimension of time to create a new four dimensional spacetime. (see Corry, L. (1997) `Hermann Minkowski and the postulate of relativity', Archive for History of Exact Sciences, 51(4), pp 273-314 for more background).  One of the concepts that Minkowski develops is that of a spacetime thread (also known as a world-line) - which maps out the x,y,z position of an element of matter over time. 

It is hard to imagine such a world-line, but the superb video of small insects flying in a shaft of sunlight in Rhode Island, is a good way of visualising how such a world-line develops. This was filmed by Dennis Hlynsky, a Professor and Dept Head of the Film/Animation/video Department at the Rhode Island School of Design. Recorded with the Black Magic pocket cinema camera in RAW, 29.9 fps 1920x1080 shutter 360 ISO200, Processed with Adobe After Effects CC. Full Video HERE.

Cluster Failure and the Future of fMRI (2016)


All science is comparative - either comparing one thing to another, or one group to another (for example Treatment vs Control) or observations to a theory. Good quality quantitative studies require a numerical answer to the question Compared to What? 

HERE is a study by Anders Eklund, Thomas E. Nichols and Hans Knutsson that asks whether the statistical methods that are routinely used in tens of thousands of functional MRI (fMRI) studies around the world are any good. 

The authors provide a long, detailed and closely argued answer to this question. The short answer is NO.
 
The authors conclusions on the Future of fMRI are as follows.

It is not feasible to redo 40,000 fMRI studies, and lamentable archiving and data-sharing practices mean most could not be reanalyzed either. Considering that it is now possible to evaluate common statistical methods using real fMRI data, the fMRI community should, in our opinion, focus on validation of existing methods. The main drawback of a permutation test is the increase in computational complexity, as the group analysis needs to be repeated 1,000–10,000 times. However, this increased processing time is not a problem in practice, as for typical sample sizes a desktop computer can run a permutation test for neuroimaging data in less than a minute. Although we note that metaanalysis can play an important role in teasing apart false-positive findings from consistent results, that does not mitigate the need for accurate inferential tools that give valid results for each and every study. Finally, we point out the key role that data sharing played in this work and its impact in the future. Although our massive empirical study depended on shared data, it is disappointing that almost none of the published studies have shared their data, neither the original data nor even the 3D statistical maps. As no analysis method is perfect, and new problems and limitations will be certainly found in the future, we commend all authors to at least share their statistical results [e.g., via NeuroVault.org] and ideally the full data [e.g., via OpenfMRI.org]. Such shared data provide enormous opportunities for methodologists, but also the ability to revisit results when methods improve years later.

Sacred Mathematics: Japanese Temple Geometry Fukagawa Hidetoshi & Tony Rothman (2008)

Sacred Mathematics:Japanese Temple Geometry
Fukagawa Hidetoshi & Tony Rothman

This is a beautiful book. It describes the Japanese art and mathematics that are combined in sangaku, or Temple Geometry. It has a foreword by Freeman Dyson, which is worth reading to understand the unique way that this book came to be.  From this Foreword:
I am lucky to have known two scholars who have devoted their lives to cultivating and teaching geometry. They are Daniel Pedoe in England and the United States, and Fukagawa Hidetoshi in Japan. Each of them had to swim against the tide of fashion. For the last fifty years, both in art and mathematics, the fashionable style has been abstract: famous artists such as Jackson Pollock produce abstract patterns of paint on canvas; famous mathematicians such as Kurt Gödel construct abstract patterns of ideas detached from anything we can feel or touch. Geometry is like representational painting, concerned with concrete objects that have unique properties and exist in the real world. Fashionable artists despise representational painting, and fashionable mathematicians despise geometry. Representational painting and geometry are left for amateurs and eccentric enthusiasts to pursue. Pedoe and Fukagawa are two of the eccentric enthusiasts. Both of them fell in love with sangaku.
 From the Blurb on the book's website:
Between the seventeenth and nineteenth centuries Japan was totally isolated from the West by imperial decree. During that time, a unique brand of homegrown mathematics flourished, one that was completely uninfluenced by developments in Western mathematics. People from all walks of life--samurai, farmers, and merchants--inscribed a wide variety of geometry problems on wooden tablets called sangaku and hung them in Buddhist temples and Shinto shrines throughout Japan. Sacred Mathematics is the first book published in the West to fully examine this tantalizing--and incredibly beautiful--mathematical tradition.

Fukagawa Hidetoshi and Tony Rothman present for the first time in English excerpts from the travel diary of a nineteenth-century Japanese mathematician, Yamaguchi Kanzan, who journeyed on foot throughout Japan to collect temple geometry problems. The authors set this fascinating travel narrative--and almost everything else that is known about temple geometry--within the broader cultural and historical context of the period. They explain the sacred and devotional aspects of sangaku, and reveal how Japanese folk mathematicians discovered many well-known theorems independently of mathematicians in the West--and in some cases much earlier. The book is generously illustrated with photographs of the tablets and stunning artwork of the period. Then there are the geometry problems themselves, nearly two hundred of them, fully illustrated and ranging from the utterly simple to the virtually impossible. Solutions for most are provided.

Shinpen Jinkoki (1689)

From the illuminating site Japanese Mathematics in the Edo period (HERE).

Shinpen Jinkoki is a three-volume book edited by Yoshida Mitsuyoshi (1598-1673). The book underwent many revisions in Mitsuyoshi's lifetime. The version published in the eleventh year of the Kan'ei era (1641) became the most widespread, and the last version Yoshida himself published was the Idai book, in the eighteenth year of the Kan'ei era (1634). 

The first volume of Shinpen mainly describes multiplications and divisions using the soroban, while the second and third volumes include an assortment of practical and recreational problems. The included problems are not arranged according to any specific order. The book includes ideas that keep readers from boredom by adopting a wide variety of problems such as calculations of areas of rice fields, problems related to the construction of rivers and banks, geometric progression, and the Josephus problem. This Shinpen Jinkoki was the most widespread version among the copies of Jinkoki widely used as a textbook for soroban throughout the Edo period.

The image below is from a 1689 edition of Shinpen Jinkoki.

A Machine Engraver - Karl Mahr (1928)


The blurb from Internet Archive

This is an advertising booklet published in the USA by the Bauer Type Foundry (Germany) in 1937. It argues that Bauer type, while machine-made, retains that "human touch." It is notable for three features, however. First, it was printed by Joseph Blumenthal's Spiral Press, one of the great commercial fine arts presses of the 20th century. It is therefore piece of fine printing uncommon in the advertising world. Second, it acknowledges as valid and important the method of making typefounding matrices by engraving a patrix and then electroforming a matrix from it. This method, while of great importance in 19th and 20th century typefounding, is often ignored or disparaged. Third, it reprints three illustrations by Karl Mahr depicting aspects of the type-making process. These appeared originally in Mahr's "Der Druckbuchstabe" (1928). 

The Book is HERE.

Painting is getting closer and closer to poetry...

From Renoir to Picasso by the French artist and writer Michel Georges-Michel (1883-1985) was published in English translation in 1957.  This is a collection of chatty first-hand accounts of artists that Georges-Michel had known through the early to mid 1900's. In 1917 he had organised an exhibition of Picasso's work in Rome. 

A quote from George Braque: Painting is getting closer and closer to poetry, now that photography has freed it from the need to tell a story. Like music, painting must have its own means of expression.

The Tibetan Book of Proportions

From the Getty Museum - more HERE. at Public Domain Review: 

An eighteenth-century pattern book consisting of 36 ink drawings showing precise iconometric guidelines for depicting the Buddha and Bodhisattva figures. Written in Newari script with Tibetan numerals, the book was apparently produced in Nepal for use in Tibet. The concept of the ‘ideal image’ of the Buddha emerged during the Golden Age of Gupta rule, from the 4th to 6th century. As well as the proportions, other aspects of the depiction – such as number of teeth, colour of eyes, direction of hairs – became very important. The V&A have produced a good guide to the iconography of the Buddha, including the 32 Lakshanas or special bodily features.

The Power of the Beautiful Experiment - an appreciation.




The scientist Israel Gelfand (1913-2009) once said:
Eugene Wigner wrote a famous essay on the unreasonable effectiveness of mathematics in natural sciences. He meant physics, of course. There is only one thing which is more unreasonable than the unreasonable effectiveness of mathematics in physics, and this is the unreasonable ineffectiveness of mathematics in biology.
HERE, in the form of a book review of Life’s Greatest Secret: The Race to Crack the Genetic Code  
by Matthew Cobb is a superb re-statement by H. Allen Orr of the same idea:
 A second theme concerns the respective roles of theory (of any sort) versus experiment in biology. In the early 1960s, mathematicians confidently declared that “it will be interesting to see how much of the final solution [to the coding problem] will be proposed by mathematicians before the experimentalists find it.” As Cobb concludes, the “answer…was simple: not one single part of it.”

The interesting question is why theory failed here. Part of the answer, as Cobb emphasizes, is related to Crick’s idea of the frozen accident. The genetic code seems at least partly arbitrary. It represents a half-decent arrangement arrived at by the imperfect, tinkering process of evolution by natural selection and, once settled on, it couldn’t be “improved,” or made somehow more systematic. In such a situation theory is likely useless.

I suspect there’s another, related, reason that theory contributed so little to cracking the code. There was, at bottom, a mismatch between the nature of the problem and the nature of much biological theory. Successful theory in biology typically plays a different part than does successful theory in, say, physics. Theory in biology often guides thought, or trains intuition, or points to patterns that might hold approximately in nature. Only rarely does biological theory provide the essentially exact results that physicists are accustomed to. (And in biology approximate results, or even rules of thumb, are often more useful than exact results.) This kind of broad-stroke theory doesn’t provide much help with a problem as specific as the coding question.

A rough analogy captures these kinds of concerns. Mathematical theory might tell you something interesting and general about combination locks: for example, that they should require a sequence of three or more numbers to prevent a would-be thief from opening them in a few random tries. But place a particular combination lock before a theorist and he’s probably no better than the rest of us at opening it.

Finally, and perhaps most important, Life’s Greatest Secret highlights the power of the beautiful experiment in science. Though Cobb pays less attention to this subject than he might have, the period of scientific history that he surveys was the golden age of the beautiful experiment in biology. Biologists of the time—including Nirenberg with his UUU, Crick and Brenner with their triplet code work, and others including Matthew Meselson, Franklin Stahl, and Joshua Lederberg—were masters of the sort of experiment that, through some breathtakingly simple manipulation, allowed a decisive or nearly decisive solution to what previously seemed a hopelessly complex problem. Such experiments represent a species of intellectual art that is little appreciated outside a narrow circle of scientists.

Another method whereby a single dot is made to represent both suit and value of card is illustrated in Figure 5. In every ornamental back almost, there is some portion of the pattern which is more or less of a fan-shaped or radial design. If this should happen to contain thirteen divisions, nothing is easier than to assign to each one a value, and thus the entire suit is represented by merely varying the position of the dot. The suit is given by placing the dot nearer or farther from the centre. Figure 5 is a diagram which illustrates this method in its simplest form.

J. Thoreau & Co's Best Quality LEAD PENCILS


From Henry Petroski's book, The Pencil (1989)

Henry David Thoreau seemed to think of everything when he made a list of essential supplies for a twelve-day excursion into the Maine woods. He included pins, needles, and thread among the items to be carried in an India-rubber knapsack, and he even gave the dimensions of an ample tent…. He wanted to be doubly sure to be able to start a fire and to wash up, and so he listed: “matches (some also in a small vial in the waist-coat pocket); soap, two pieces.” He specified the number of old newspapers (three or four, presumably to be used for cleaning chores), ….
… he advised like-minded observers to carry a small spyglass … a pocket microscope … tape measure … and paper and stamps, to mail letters back to civilization.
But there is one object that Thoreau neglected to mention, one that he most certainly carried himself. For without this object Thoreau could not have sketched … fauna…. Without it he could not label his blotting paper … or his insect boxes … record measurements … write home … make his list. Without a pencil Thoreau would have been lost in the Maine woods.
According to his friend Ralph Waldo Emerson, Thoreau seems always to have carried, “in his pocket, his diary and pencil.” So why did Thoreau … neglect to list even one among the essential things to take on an excursion? Perhaps the very object with which he may have been drafting this list was too close to him, too familiar a part of his own everyday outfit, too integral a part of his livelihood, too common a thing for him to think to mention.

The Stereoscope and Stereoscopic Photography (1890)

In 1859 Oliver Wendell Holmes published an article in the Atlantic magazine on the Stereoscope and the Stereograph. He had this to say of this technology:
 Form is henceforth divorced from matter. In fact, matter as a visible object is of no great use any longer, except as the mould on which form is shaped. Give us a few negatives of a thing worth seeing, taken from different points of view, and that is all we want of it. Pull it down or burn it up, if you please. We must, perhaps, sacrifice some luxury in the loss of color; but form and light and shade are the great things, and even color can be added, and perhaps by and by may be got direct from Nature.

There is only one Coliseum or Pantheon; but how many millions of potential negatives have they shed,—representatives of billions of pictures,—since they were erected! Matter in large masses must always be fixed and dear; form is cheap and transportable. We have got the fruit of creation now, and need not trouble ourselves with the core. Every conceivable object of Nature and Art will soon scale off its surface for us. Men will hunt all curious, beautiful, grand objects, as they hunt the cattle in South America, for their skins, and leave the carcasses as of little worth.
