Bacterealistic Art

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.” — Albert Einstein, Living Philosophies (Simon and Schuster, New York, 1931).

They (Science and Art) ask the same questions… really what it (Science) does at its best is force us to reassess our place in the cosmos. Where do we come from? Who are we? Where are we going? And those are the very same questions that you get in art, literature, music. Every time you read a wonderful book or see a wonderful film, you come out of it with a different perspective of yourself, and too often, it seems to me, we forget that cultural aspect of science…” — Lawrence Krauss, Interview on the National Public Radio, 2011.

As many accomplished scientists agree, there is a profound and enduring relationship between science and art. In a lecture, Robert Eskridge, Executive Director of Museum Education, at the Art Institute of Chicago, pointed out the nature of this relationship:

Science and art naturally overlap. Both are a means of investigation. Both involve ideas, theories, and hypotheses that are tested in places where mind and hand come together—the laboratory and studio. Artists, like scientists, study—materials, people, culture, history, religion, mythology— and learn to transform information into something else. In ancient Greece, the word for art was techne, from which technique and technology are derived—terms that are aptly applied to both scientific and artistic practices.

Today I learnt about a scientist, whose unusual art-form fascinated me and I wanted to share it with all. He is Professor Eshel Ben-Jacob, a theoretical and experimental physicist at the Raymond and Beverly Sackler School of Physics and Astronomy, and the Sagol School of Neuroscience, Tel Aviv University. He holds the Maguy-Glass Chair in Physics of Complex Systems, and is a Fellow of the National Science Foundation (NSF) Frontier Center for Theoretical Biological Physics (CTBP) at the University of California at San Diego (UCSD). He is an acclaimed expert in the field of self-organization and pattern formation in open and complex systems.

In the late 1980s and early 1990s, Professor Ben-Jacob began to study of bacterial self-organization and pattern formation, using two strains of soil bacteria, the Paenibacillus dendritiformis and the Paenibacillus vortex; he pioneered the study of the adaptive intelligence and social cooperation that these bacteria demonstrate in complex, hostile environments. Under laboratory-induced stress, these bacteria employ chemical mediators to communicate amongst themselves and cooperate in order to adapt to the stress, facilitating survival. Ben-Jacob, in collaboration with Professor Herbert Levine of the NSF Frontier CTBP, applied biophysical principles, advanced modeling, and molecular biology to unravel the mechanisms behind the bacterial cooperativity, task allocation, learning and decision-making that lead to the generation of complex patterns on artificial media – all of which have significance for both beneficial and harmful bacteria that living beings encounter.

Once these complexly patterned colonies are formed, Ben-Jacob uses simple stains, such as Coomassie Brilliant Blue, and digital color modification to produce absolutely stunning, artistic images of these bacteria. Some of these fascinating images can be seen on his gallery pages (1, 2 and 3), or as a slide show.

Let me finish with the video of a lecture that Professor Ben-Jacob presented at Google in 2011, in which he talks about how social networks can be informed by bacterial colony morphology patterns and the cooperative information processing undertaken by them.

I Ponder the Mystery of Physics… And Physicists

As a species, physicists baffle me. To my meager understanding, Physics – the study of matter, energy and the relationship between them – is the most fundamental of the natural sciences. Physics elucidates the properties of matter at level of the most basic structural units, and therefore, must necessarily underlie our understanding of the other branches of the natural sciences, namely, chemistry and biology. Therefore, I have always assumed – perhaps naïvely – the physicists’ understanding of the natural world is firmly rooted in empiricism, in critical analysis of observed data – in other words, in the conscientious application of the Scientific Method.

The Man Whose Name Boson Honors

In the past several days, the world was waiting agog for the news: is it there or is it not? As the Honorable Beeb reported:

The most coveted prize in particle physics—the Higgs boson—may have been glimpsed, say researchers reporting at the Large Hadron Collider (LHC) in Geneva; Scientists say that two experiments at the LHC see hints of the Higgs at the same mass, fueling huge excitement. But the LHC does not yet have enough data to claim a discovery.
