A map of science

Saturday, March 6th, 2010

This is an interesting visualization of the whole science (or almost whole:). The image was constructed by sorting roughly 800,000 scientific papers into 776 different scientific paradigms (shown as red and blue circular nodes) based on how often the papers were cited together by authors of other papers. Links (curved lines) were made between the paradigms that shared common members, then treated as rubber bands, holding similar paradigms closer to one another when a physical simulation forced them all apart: thus the layout derives directly from the data. Larger paradigms have more papers. Labels list common words unique to each paradigm. Readable in close-up here:

The neuroscience of screwing up

Saturday, February 20th, 2010

We should watch carefully and acknowledge our failures, because they may occur more important to us than the success. Accept defeat, says the fabulous article in Wired magazine.

Kevin Dunbar is a researcher who studies how scientists study things — how they fail and succeed. Philosophers have long theorized about how science happens, but Dunbar wanted to get beyond theory. He wasn’t satisfied with abstract models of the scientific method — that seven-step process we teach schoolkids before the science fair — or the dogmatic faith scientists place in logic and objectivity. Dunbar knew that scientists often don’t think the way the textbooks say they are supposed to. He suspected that all those philosophers of science — from Aristotle to Karl Popper — had missed something important about what goes on in the lab. Dunbar’s findings stated that science is a deeply frustrating pursuit. Although the researchers were mostly using established techniques, more than 50 percent of their data was unexpected. (In some labs, the figure exceeded 75 percent.)

How did the researchers cope with all this unexpected data? How did they deal with so much failure? Dunbar realized that the vast majority of people in the lab followed the same basic strategy. First, they would blame the method. Then the experiment would be repeated. This is when things get interesting. According to Dunbar, even after scientists had generated their “error” multiple times — it was a consistent inconsistency — they might fail to follow it up.“People have to pick and choose what’s interesting and what’s not, but they often choose badly.” And so the result was tossed aside, filed in a quickly forgotten notebook. The scientists had discovered a new fact, but they called it a failure.

The reason we’re so resistant to anomalous information — the real reason researchers automatically assume that every unexpected result is a stupid mistake — is rooted in the way the human brain works. Over the past few decades, psychologists have dismantled the myth of objectivity. The fact is, we carefully edit our reality, searching for evidence that confirms what we already believe. Although we pretend we’re empiricists — our views dictated by nothing but the facts — we’re actually blinkered, especially when it comes to information that contradicts our theories. The problem with science, then, isn’t that most experiments fail — it’s that most failures are ignored. But the unexpected result could be the major breakthrough in particular scope, so we should keep our eyes open.

On randomness, part 2

Thursday, November 5th, 2009

What does randomness look like? Random walk project by Daniel A.Becker explores the notion of randomness. It consists of 14 double-sided A2 posters contained in a transparent plastic sleeve. Ten sheets explain the phenomena of randomness in mathematics and physics – four focus on all-day randomness and the quality of pseudo random number generators. Without title or specific order the sleeve contains the folded sheets at random like a pack of cards. It has no thematic order, unlike the playing cards in a pack. The layouts of the poster backs are visually influenced by randomness. Each reverse side is unique as is the reverse of the same topic in different sets. Visualizations and random layouts are made with the program “proce55ing”.

Claude Lévi-Strauss died

Wednesday, November 4th, 2009

It has to be mentioned about. Claude Lévi-Strauss, the French anthropologist whose revolutionary studies of what was once called “primitive man” transformed Western understanding of the nature of culture, custom and civilization, has died at 100. I was writing about his 100th birthday a year back on this blog. Undoubtedly, he was one of the greatest minds of the 20th century!

On randomness, part 1

Wednesday, October 21st, 2009

The notion of randomness has been within my top interests for some time now. Random is defined as “made, done, happening or chosen without method or conscious decision” (Oxford American Dictionaries) or “having no definite aim or purpose; not sent or guided in a particular direction; haphazard” (Oxford English Dictionary).

Most often used in mathematical theory of probability arose from attempts to formulate mathematical descriptions of chance events and in statistics where random process is a repeating process whose outcomes follow no describable deterministic pattern, but follow a probability distribution.

In religious systems a highly deterministic worldview makes randomness not possible; the concepts of purpose and meaning exclude randomness completely (except for Discordianism:). In evolution theory, on the other hand, the selection is applied to the results of random genetic variation.

In regard to our lives, what seems the most the most fascinating is whether randomness equals unpredictability? Does it mean floating within a chaotic system? And how can you say whether a process is truly random?

Darwin&Art. Do we have “art instinct”, part 2

Sunday, March 29th, 2009

charlesdarwin_1337_18939411_0_0_12181_300

The exhibition Darwin: Art and the Search for Origins, running at the Shirn Kunsthalle in Frankfurt, Germany, looking at how artists responded in the century following the publication of Darwin’s On the Origin of Species looks at how artists responded in the century following the publication of Darwin’s On the Origin of Species. One of the heros of the exhibit is Ernst Haeckel, German biologist and philosopher, famous for his “Art forms in nature”, who I’ve been writing about a few weeks ago in the context of vovlox font system. Now, I came across beautiful true story how he started to draw nature which was a profound input in Darwinian theory spreading all over the world. He was a talented and promising zoologist when his wife Anna Sethe died which made him abandon religion and direct his paths towards Darwinism. He was trying to recover by the Mediterranean seashore and while walking along the beach he noticed a jellyfish. Its delicate yellow tendrils reminded him of his wife’s braids and he started to draw them and named them “annasethe”. So he begun sketching and drawing marine life which revolutionized the 19th cent. understanding of the species. It’s that inspiring? This story made me take a closer look at the way we come to fresh ideas, the concept of serendipity and innovation in thinking, also in relation to neuroscience. Now working on that topic, so some thoughts soon, I hope.

Darwin & Art. Do we have “art instinct”?, part 1

Wednesday, March 25th, 2009

The convergence and mutual influences of art and science has been of my interest for some time. This year we celebrate 200th anniversary of Darwin’s birthday and the most positive aspect of it is that many publishers are issuing books related to darwinism now ( …plus maybe anti-creationist debate arising more widely, but it’s a different topic:).

Denis Dutton in “The Art Instict” interprets Darwinism through sociobiology, the idea that social behavior is driven by genes. Are we prisoners of our genes or not? If that question answers irresponsible thinker, it it may reach the edges of extreme conservatism, which is the thesis of Jackie Wullschlager from Financial Times referring to Dutton, professor of aesthetic and philosophy. He believes that:” the evolution of Homo sapiens is not just a history of how we came to have acute colour vision, a taste for sweets and an upright gait. It is also a story of how we became a species obsessed with creating artistic experiences … from firelit caves to the continuous worldwide glow of television screens.”

And he gives some more picturesque examples to prove his thesis that we as species have a kind of “art instinct” = common taste deriving from our ancestor’s mind. Yeah! So much the thesis. Time for the proofs. “We like bright rolling landscapes, because they remind us of the African savannah where human beings evolved. Centuries of portraits illustrate our admiration for male height and vigour: Velázquez’s monarchs, for example. And: our predilection for female Coke-bottle figures that promise fertility, such as Botticelli’s Venus”. Too show that those “art insticts” are innate, he “falls back on Darwinian survival theories: The aesthetic, like the erotic, arises spontaneously as a source of pleasure in cultures across the globe,” he offers.

True, but while sex is essential to the continuation of the humankind, art is not. “Never mind, says Dutton. Art has “survival value” for the species because it increases “empathy, co-operation and social solidarity”, and therefore makes communities which practice it more likely to stay happy, healthy and reproductive.” Well, this clear thought that art is being made to make sex is a little bit too much for me. Or..?

Sixth sense on your neck

Truly amazing future device revolutionizing the way we interact with the environment called “Sixth sense” developed by my beloved MIT Media Lab team. Those people are incredible — they shape the world we will be living in within next few years.

Century of all-consuming Self: Happiness machines

Saturday, February 28th, 2009

Very interesting BBC documentary about human striving for happiness (in two parts). Beginning form Freud’s theory it tries to uncover the great forces which are used to control the masses in the modern democracy. The first episode is about Freud’s nephew Edward Bernays who broke the taboo on women smoking by persuading them that cigarettes were a symbol of independence and freedom. But Bernays was convinced that this was more than just a way of selling consumer goods. It was a new political idea: by satisfying the inner irrational desires that his uncle had identified, people could be made happy and ready to be controlled. It was the start of the all-consuming self which unfortunately has come to dominate today’s world.

Volvox/Art forms in nature

Tuesday, January 6th, 2009

typecutsvolvox

Volvox is a system of 5 fonts (volvox 1, 2, 3, 4, 5) that create a variety of ornamental composites by superimposing.
Each Volvox font contains a set of 26 illustrations that are all characterized by radial symmetry.
Since all the shapes are concentrically composed – which means they all share the same width as well as the same center – they all align perfectly centered.
Volvox is the latin term for any of various freshwater green algae that form spherical multicellular colonies.
Concerning volvox as a system of fonts this means that even though each Volvox character is able to function by itself, it is ultimately designed to be an integral part of a more complex structure (that is created by superimposing various shapes).
Volvox is inspired by the natural aesthetics of scientific drawings especially by the beautiful illustrations of Ernst Haeckel in Art forms in nature about which I was once writing on my old blog.

tafel_017_medium1

The design of all volvox characters is based on a certain hierarchy:
Volvox 1 = background_shapes
Volvox 2 = leading_shapes
Volvox 3 = centerpiece_shapes
Volvox 4 = bits&pieces_shapes
Volvox 5 = line_shapes

With the Volvox engine the user is able to create an endless variety of Volvox composites (the hierarchical order above is not obligatory while using the Volvox engine).
