  • BIG DATA & MÉDECINE PERSONNALISÉE : OÙ EN SOMMES-NOUS ?

    Published on Feb 6, 2017

    Big Data en biologie et médecine : nouveaux outils, nouveaux concepts ?

    Ces dix dernières années a vu l’émergence d’une nouvelle approche en biologie, appelée biologie des systèmes, qui s’appuie sur l’acquisition de données aussi exhaustives que possible concernant le système à l’étude. Ces données sont d’ordre génétique (ex : séquence du génome), moléculaires (ex : niveau d’expression de tous les gènes), phénotypiques (ex : pression artérielle, poids, mesures issues d’objets connectés), et aussi d’ordre qualitatif tel que des images ou radios. Une interprétation appropriée de l’ensemble massif de ces données –d’où le nom « Big Data », devenu très médiatisé, ou mégadonnées– serait la porte ouverte à une compréhension intégrative des phénomènes du vivant, tant physiologiques que pathologiques. De ce fait, autant en biologie fondamentale qu’en médecine, dans le cadre de la médecine dite personnalisée, cette approche suscite d’énormes attentes, alors même que de nombreux défis restent à adresser. L’enjeu est non seulement scientifique, mais aussi sociétal, économique, et politique.

    Cet exposé revient plus spécifiquement sur l’intrication « Big Data », complexité, et médecine personnalisée, en faisant le lien avec le développement de la modélisation, entre réalités, promesses et leurre.

    Conférence de Béatrice Desvergne, professeur à la Faculté de Biologie et de Médecine de l'Université de Lausanne, professeure invitée par le labex TransferS et Michel Morange (République des Savoirs).

    Médecin, biologiste et philosophe, Béatrice Desvergne est professeure au Centre intégratif de génomique (CIG) de l’UNIL et vice-Doyenne en charge de l’organisation de la Section des sciences fondamentales, à la Faculté de Biologie et de Médecine de Université de Lausanne en Suisse.

    En 2012, elle a été désignée Doyenne de la Faculté de biologie et de médecine (FBM) . Une nomination historique, puisque Béatrice Desvergne est devenue ainsi la première femme à la tête d’une Faculté de médecine en Suisse romande.

    ABONNÉ 9,1 K
    L'Institut Henri Poincaré produit un documentaire exclusif de 32 minutes sur le mathématicien d'exception Joseph-Louis Lagrange, en coproduction avec le CNRS Images et en partenariat avec l'Institut Lagrange de Paris. Des historiens retracent le parcours européen de Lagrange et montrent comment il est passé d'académicien protégé des puissants à un professeur chargé d'éduquer les nouveaux Citoyens au moment de la Révolution Française. Ils posent la question de l'implication des scientifiques dans la vie politique de l'époque. Des scientifiques expliquent combien les travaux de Lagrange, notamment en analyse et en mécanique céleste, sont novateurs dans la façon de concevoir les problèmes à l'époque, et permettent de comprendre comment il s'est positionné à la frontière entre les mathématiques et la physique, et a pu profondément marquer les sciences et leur enseignement jusqu'à aujourd'hui. Malgré l'omniprésence de Lagrange dans les mathématiques et la physique moderne (Equations de Lagrange, Points de Lagrange, Interpolation de Lagrange, Lagrangien, etc...), la vie de ce savant de l'époque des Lumières reste méconnue... Remerciements : Bruno Belhoste - Anne-Sophie Bonnet-Bendhia - Jenny Boucard - Alberto Conte - Laurent Guin - Eberhard Knobloch - Jacques Laskar - Thomas Morel - Maria Munoz - Luigi Pepe - Jérôme Pérez - Silvia Roero. Production : Cédric Villani, Jean-Philippe Uzan Direction scientifique : Frédéric Brechenmacher Réalisateur : Quentin Lazzarotto En collaboration avec le CNRS Images et en partenariat avec l'Institut Lagrange de Paris.

  • Stop Teaching Calculating, Start Learning Maths! - Conrad Wolfram

    Ajoutée le 25 oct. 2013
    ABONNÉ 11 K
    'Stop teaching calculating, start learning maths' - Conrad Wolfram on how re-conceptualized maths in education can step up to real-world needs. The importance of maths to jobs, society and thinking has exploded over the last few decades. Meanwhile, maths education fails to match-up. Why has this chasm opened up? Computers are central: when they do the calculating, people work on harder questions, try more concepts, and play with a multitude of new ideas. Conrad Wolfram explained why this fundamental shift is needed in education, and described the major project he's founded to build a dramatically new, problem-centric, computer-based maths curriculum. He asked which country could adopt a computer-based approach first, and leapfrog others in STEM. MORE about Conrad Wolfram: http://www.wise-qatar.org/content/mr-...

    The entire field of chemistry summarised in 12mins from simple atoms to the molecules that keep you alive.This video was sponsored by The Great Courses Plus, start your free trial and help out this channel here http://ow.ly/crsQ30beNOZ If you would like to buy a poster of this map, they are available here: https://www.redbubble.com/people/domi... I have also made a version available for educational use which you can find here: https://flic.kr/p/UBS4mf and a widescreen version: https://flic.kr/p/UNA1LW Errata and notes: 1. I got the Oxidising Agent and the Reducing Agent the wrong way around! Sodium is the Reducing agent and Chlorine is the Oxidising agent. My confusion was that when a sodium atom looses an electron it becomes oxidised, so in my simple brain, I called it the oxidising agent. That is wrong because the agent that oxidises the sodium is the chlorine atom and so the labels are the wrong way around. Doh! 2. I drew the hydrogen H2 molecule with a double bond but it should be a single bond because they are bonded with a single covalent bond. 3. Where I have drawn carbon dioxide, the carbon should have a double bond to each of the oxygens. 4. Apparently Feynman diagrams are not that useful for theoretical chemistry, so perhaps that wasn't the best choice for the illustration. The feedback in the comments from a real theoretical chemist is "All we deal with is shuffling around electrons, but many many many electrons, so a Feynman diagram would need to be huge but at the same time would be very very repetitive." 5. In analytical chemistry, I should have called it distillation rather than precipitation. 6. My definition of organic chemistry being about ‘life’ is not very good. I should have said that organic chemistry looks at compounds that contain carbon. But there are some compounds in inorganic chemistry that also contain carbon, like carbon dioxide so I guess I'd also have to state that inorganic chemistry is almost everything else. 7. I said that fuels are inorganic chemistry which is misleading when I drew a car next to it. My understanding is that there are inorganic fuels that don't contain carbon, but obviously all the fuels we are familiar with are organic. I thought a picture of a car would tie a few things together elegantly, but it ended up giving the wrong impression. That’s okay, I’m still learning! :D 8. In inorganic chemistry, I should have stated that all natural minerals fall under inorganic chemistry so as not to be misleading, otherwise you might go way thinking that only man-made substances fall under inorganic chemistry which is not true. I said that 'a lot of the inorganic compounds that are studied are man-made' meaning that the cutting edge of research is mostly man-made substances. 9. Apparently water is not the most inflammable substance. I thought it was so that is interesting. 10. In the bonding section, hydrogen bonding and van der waals forces are technically inter molecular forces.

    Everything we know about physics - and a few things we don't - in a simple map. If you are interested in buying a print you can buy it as a poster here: http://www.redbubble.com/people/domin... Or on a load of other objects: http://www.redbubble.com/people/domin... Also you can download a digital version here: https://www.flickr.com/photos/9586967... I made the music, which you can find on my Soundcloud if you'd like to get lost in some cosmic jam. https://soundcloud.com/dominicwalliman Errata and clarifications. I endeavour to be as accurate as possible in my videos, but I am human and definitely don’t know everything, so there are sometimes mistakes. Also, due to the nature of my videos, there are bound to be oversimplifications. Some of these are intentional because I don’t have time to go into full detail, but sometimes they are unintentional and here is where I clear them up. 1. “Isaac Newton invented calculus.” Actually there is controversy over who invented calculus first Isaac Newton or Gottfried Leibniz. Regardless of who it was I have used Leibniz’s mathematical notation here and so he definitely deserves credit. I did’t know about all this so thanks to those who pointed it out. https://en.wikipedia.org/wiki/Leibniz... 2. “Maxwell derived the laws of electromagnetism.” This is a simplification as Maxwell’s work was built on the backs of other scientists like Hans Christian Ørsted, André-Marie Ampère and Michael Faraday who discovered induction and saw that electricity and magnetism were part of the same thing. But it was Maxwell who worked out all the maths and brought electricity and magnetism together into a unified theory. https://en.wikipedia.org/wiki/Electro... 3. “Entropy is a measure of order and disorder”. This is also a simplification and this does a good job of explaining it better https://en.wikipedia.org/wiki/Entropy 4. Einstein and Quantum physics: I made it sound like quantum physics was built by people other than Einstein, but this couldn’t be further from the truth. Einstein got a Nobel prize for his work on the photoelectric effect which was a key result to show the particle-like nature of light. Funnily enough he never got a nobel prize for his work on Relativity! Also, if you enjoyed this video, you will probably like my science books, available in all good books shops around the work and is printed in 16 languages.

I have also made a version available for educational use which you can find here: https://www.flickr.com/photos/9586967... To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors! 1. The number one is not a prime number. The definition of a prime number is a number can be divided evenly only by 1, or itself. And it must be a whole number GREATER than 1. (This last bit is the bit I forgot). 2. In the trigonometry section I drew cos(theta) = opposite / adjacent. This is the kind of thing you learn in high school and guess what. I got it wrong! Dummy. It should be cos(theta) = adjacent / hypotenuse. 3. My drawing of dice is slightly wrong. Most dice have their opposite sides adding up to 7, so when I drew 3 and 4 next to each other that is incorrect. Thanks so much to my supporters on Patreon.

  • CAPITALISME & ACCÉLÉRATION NUMERIQUE - [Daniel Cohen et Alexandre Cadain]

    Ajoutée le 15 mars 2017
    ABONNÉ 14 K
    Le nouvel esprit du capitalisme, à l’âge de l’accélération numérique. 00:00:00 Alexandre Cadain 00:25:21 Daniel Cohen 01:29:52 Questions La société industrielle était parvenue à sceller l’unité d’un mode de production et d’un mode de protection, à la manière des sociétés féodales… Aujourd’hui, la nouvelle économie numérique installe un modèle productif à « coût-zéro », totalement disruptif. Des logiciels bon marché absorbent les tâches routinières, quelque soit leur niveau de sophistication, du jeu d’échecs aux transactions boursières en passant par les distributeurs de billets. Google fait conduire des voitures par des ordinateurs. Au Japon, des robots s’occupent des personnes âgées. La tension nerveuse des humains est poussée à des niveaux inédits pour échapper à la marée montante du numérique, comme si toute activité qui tend à se répéter était par avance condamnée à être remplacée par un logiciel. Pour reprendre une formule de Pierre Legendre, juriste et psychanalyste, l’homme moderne vit « au dessus de ses moyens psychiques ». La question qui se pose, plus que jamais est simplement la suivante: comment réconcilier la croissance à l’âge numérique avec l’idée de progrès, dans sa double signification matérielle et morale? Daniel Cohen est un économiste français. Il est directeur du département d’économie à l’École normale supérieure, et professeur à Paris I et à l’École d’économie de Paris dont il est le vice-président. Il est aussi directeur du Centre pour la recherche économique et ses applications (CEPREMAP). Membre du Conseil d’analyse économique (CAE) auprès du Premier ministre et conseiller scientifique auprès du Centre de développement de l’OCDE. Il s’intéresse en particulier à l’économie des pays en développement, à leur dette et leur productivité. Daniel Cohen se définit comme un économiste pragmatique. Il est l’auteur d’une douzaine d’ouvrages dont plusieurs ont été primé, comme « Homo Economicus », chez Albin Michel, meilleur livre d’économie 2012. Son dernier ouvrage, « Le monde est clos et le désir infini » est paru aux mêmes éditions en 2015. Il est par ailleurs éditorialiste au Monde. Alexandre Cadain est un entrepreneur et chercheur en intelligence hybride (naturelle, collective, artificielle). Ancien de l'ENS Ulm, il a développé ses recherches sous la direction de Daniel Cohen sur la croissance endogène et les technologies exponentielles. Il co-dirige le programme de recherche Postdigital de l’ENS Ulm où sont explorés nos futurs technologiques, en particulier liés à l’intelligence artificielle. A Los Angeles, il a rejoint la fondation d'innovation XPRIZE avec IBM Watson pour identifier et accompagner les projets internationaux les plus prometteurs en intelligence artificielle. Depuis début 2016, il est responsable des affaires gouvernementales d’Hyperloop Transportation Technologies en Europe et dirige le projet en France en particulier. /////////////////////////////////////////////////////////////////////////////// ►ENS : http://www.ens.fr ►SAVOIRS ENS : http://www.savoirs.ens.fr ►FACEBOOK : https://www.facebook.com/Ecole.normal... ►TWITTER : https://twitter.com/ENS_ULM ►INSTAGRAM : https://www.instagram.com/normalesup
