Biology needs a Grothendieck (or at least a Hilbert) Original author here - I just discovered this thread. Thanks so much for all the comments! Some context behind why I wrote this post: as a researcher and technologist in biology, I've realized that it's unclear to me what the real questions are; that this lack of clarity is not due to my immaturity; and the field seems dangerously aimless.

>99% of the time, work is justified (and finished) with some application to health and medicine, with little regard for theory building or true understanding of a system. Bringing up this point usually solicits two responses: 1) we don't have enough data yet 2) there's little use for theory in biology. I hope I can give more in depth responses where I see these themes in other comments, but I'll generalize my thoughts here.

First, how do we judge what questions are worth asking and researching, vs trivial details? How do we even know whether we understand whether a question has been adequately answered? Alexander Grothendieck | Bits of DNA. I’m a (50%) professor of mathematics and (50%) professor of molecular & cell biology at UC Berkeley. There have been plenty of days when I have spent the working hours with biologists and then gone off at night with some mathematicians. I mean that literally. I have had, of course, intimate friends among both biologists and mathematicians. I think it is through living among these groups and much more, I think, through moving regularly from one to the other and back again that I have become occupied with the problem that I’ve christened to myself as the ‘two cultures’.

I try not to become preoccupied with the two cultures problem, but this holiday season I have not been able to escape it. It therefore came as a surprise to me to read his post titled “Can one explain schemes to biologists?” John Tate and I were asked by Nature magazine to write an obituary for Alexander Grothendieck. Mumford goes on in his blog post to describe the reasons Nature gave for rejecting the obituary. For . And. Alexander Grothendieck | Bits of DNA. Home | Catalogue of Life.

Received: June 9, 2003. The applicability of dimensional analysis (DA) is discussed in relation to the metabolic scaling laws. Key terms: Dimensional analysis. In accordance with Rosen (1983): "the essence of similarity leads to some of the deepest issues in all of science, as for instance when physiological data are compared with theoretical models of mathematical, chemical, physical or biological nature.

" A New Thermodynamics Theory of the Origin of Life | Quanta Magazine. Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.” From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat.

Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity.

Intrication quantique, base ADN de la vie?

Les discussions autour de la mécanique quantique ont le plus souvent un caractère quelque peu abstrait: les effets quantiques ne sont pas vraiment perceptibles en tant que tels dans notre monde classique, et les considérations d’intrication, de fonctions d’ondes et de définition du réel ne semblent pas très liés à ce que nous avons de plus cher, à savoir la vie elle-même. La vie, cette chose humide et chaude, évolutive, déclinée sous tant de facettes de la science, semble bien ne pas devoir trop se préoccuper de la manière dont les photons et autres bosons s’amusent dans leur monde probabiliste et mathématique.

Et pourtant. Nous savons depuis la fameuse découverte de l’acide désoxyribonucléique par le biologiste Jim Watson et le physicien James Crick, en 1953, que la vie se constitue sur base de gènes et que ceux-ci dépendent d’une molécule très particulière en double hélice à l’acronyme universellement connu, l’ADN.
