Ce collectif propose 25 anecdotes qui nous font voyager à travers des triangles rectangles et des cordes vibrantes, des expériences de laboratoire et des récits de terrain, des idées qui ont changé le monde et d’autres qui continuent de l’interroger. Un voyage où l’on croise Ératosthène, Pythagore et Darwin, mais aussi des chercheurs d’aujourd’hui, des enseignants passionnés, des voix multiples. Derrière chaque anecdote se cache une invitation à regarder autrement, à s’étonner encore, et à se rappeler que les sciences et les mathématiques ne sont pas seulement des outils, mais aussi des sources inépuisables de sens et de beauté.

Depuis plus de 20 ans, le bien-être animal s’impose comme un enjeu sociétal majeur. Plus de 90 % des Français estiment qu’il devrait être mieux protégé pour les animaux d’élevage (Eurobarometre 2023). Au cours de cette même période, des avancées majeures ont été réalisées : la définition du bien-être a été recentrée sur l’individu et ses états mentaux positifs, les outils d’évaluation du bien-être en élevage ont été affinés, et de nombreuses pratiques d’élevage ont été améliorées.

Cet ouvrage replace ces progrès dans leur contexte scientifique et politique avant d’aborder des thématiques clés : l’évaluation des états mentaux, front de science au cœur des recherches internationales ; l’enrichissement du milieu de vie en prenant l’exemple des poissons, encore peu étudiés sous l’angle de leurs expressions émotionnelles ; et la compréhension et la prise en charge de la douleur animale. Sont également présentées des innovations techniques - avec le développement de capteurs et d’outils numériques pour aider à l’évaluation du bien-être des animaux, et méthodologiques – avec l’utilisation des sciences participatives. Enfin, deux contributions invitent à considérer le bien-être animal comme un élément de la multi-performance des systèmes d’élevage, et comme un élément d’une vision élargie du bien-être au sein du One Welfare intégrant celui des éleveurs.

Cet ouvrage propose ainsi une vision originale et pluridisciplinaire du bien-être des animaux d’élevage, à destination des professionnels, des enseignants, des étudiants, des chercheurs et de tous ceux qui s’engagent pour un élevage durable et respectueux des animaux.

Née en Europe au XVI^e siècle, la science moderne est l’héritière des traditions savantes de l’Ancien Monde. Son essor est étroitement lié aux grandes mutations de l’époque moderne  : développement des échanges et découverte du Nouveau Monde, divisions confessionnelles, formation des États modernes, émergence de nouvelles techniques...
S’appuyant sur les travaux les plus récents en histoire des sciences, ce livre explore les différentes facettes de cette histoire. Il retrace l’exploration du monde à la Renaissance, analyse ce qu’il est convenu d’appeler parfois la révolution scientifique, de Copernic à Newton, et décrit la place centrale occupée par les sciences dans le mouvement des Lumières. Il montre comment la science moderne a accompagné pendant trois siècles le processus de sécularisation qui caractérise la modernité.

The field of investigation of astronomical spectroscopy is vast and can provide a wealth of information about the celestial objects observed (Planets, stars, nebulae, novae, supernovae, galaxies, quasars) through the light they emit. Indeed, this light can be broken down into an atomic spectrum, and based on its analysis and current knowledge of physics, it is possible to determine various characteristics of the star being studied.
This book presents methods and tools used for spectrum analysis and covers topics such as:
– the measurement of velocity (radial, orbital, rotational, redshift),
– the evolution over time in certain spectral lines,
– the explosion of a nova or supernova,
– the physical nature of an object (is it a planetary nebula? Is it a galaxy?).
Spectroscopy also allows for the reconstruction of an image by digitizing the surface of a planetary nebula at a given wavelength. It is also possible to estimate the temperature of a star and even evaluate its density.
For each chapter, the author indicates the type of equipment to be used (optics, camera, spectrograph) and explains step-by-step the methodology for producing the necessary data (acquisition, data processing, etc.) using ten concrete examples that the author has tested himself.
This book is intended for amateur astronomers who are curious to learn what can be gleaned from a spectrum so that they can then make their own observations and analyses sometimes rivaling those of professionals !

Service integration and management (SIAM) is a management methodology for creating value in an ecosystem where multiple service providers contribute to end-to-end services. It has evolved as organizations moved from single-supplier outsourcing to multi-sourced, increasingly digital, cloud-enabled delivery, where objectives, contracts, data and targets can become misaligned.

SIAM enables cross-functional, cross-process and cross-provider integration by establishing a service integrator capability that coordinates governance, management, assurance and continual improvement. It creates an ecosystem where all parties understand their role, responsibilities and context, are empowered to deliver within boundaries, and are accountable for the outcomes they enable.

SIAM Professional, third edition, forms part of the refreshed Scopism SIAM Body of Knowledge and is the official guide for the EXIN SIAM™ Professional certification. This book supports candidates preparing for the certification and focuses on applying SIAM in practice, building on the concepts introduced in SIAM Foundation. The book will appeal to:

• Practitioners who want to deepen their SIAM capability and achieve the SIAM™ Professional certification
• Customer organizations seeking practical guidance for operating and improving multi-provider services
• Service integrators and their teams delivering integrated, outcome-focused governance
• Internal and external service providers wanting clarity on how to collaborate in a SIAM ecosystem
• Consultants in service management and related frameworks looking to extend their expertise

“Over the last decade we’ve seen SIAM gain relevance across increasingly complex provider landscapes and supply chain management challenges. The updated SIAM Body of Knowledge offers a renewed look at the core concepts of multi-provider management but extends the breadth and depth of this with additional and flexible Compendiums. More than 75 experts from around the world offered their knowledge, experience and thoughts to provide content that is applicable and suitable for any type of organization.

As part of the Body of Knowledge, SIAM Professional does exactly that; it expands on the foundational concepts, offering advice and examples that transform SIAM theory and common sense to practically applicable guidance. We hope practitioners can find knowledge and inspiration from this publication to improve their organizational operating model.”

L’agriculture est au cœur de nos vies, mais elle est aussi au cœur de nombreux malentendus. Entre idées reçues, discours simplificateurs et positions tranchées, il devient parfois difficile de distinguer les faits des opinions. Cet ouvrage propose de prendre le temps de comprendre l’agriculture dans toute sa complexité, en s’appuyant sur des connaissances solides, accessibles et mises en perspective. Il explore les bases historiques, techniques et réglementaires du monde agricole, depuis son organisation jusqu’aux pratiques de production végétale et animale. Il présente également les définitions des différentes formes d’agriculture – raisonnée, intégrée, de conservation, biologique… – dont on parle beaucoup sans toujours en connaître les réalités de terrain. Enfin, des rubriques dédiées (« À nuancer ») proposent de mettre en perspective certaines affirmations largement relayées, en les confrontant à des données factuelles et à des publications scientifiques reconnues. Et l’on s’aperçoit que, comme souvent dans le monde du vivant, la réalité n’est pas si simple, qu’elle se situe entre les extrêmes et qu’il n’existe pas une réponse unique aux questions que vous vous posez. Conçu comme une version simplifiée et largement illustrée du Petit précis d’agriculture du même auteur, ce livre facilite l’appropriation des notions grâce à de nombreuses photos, schémas et illustrations. Il s’adresse avant tout aux élèves et étudiants des formations agricoles parfois déroutés par la complexité du sujet, et à toute personne souhaitant mieux comprendre l’univers agricole de manière éclairée.

L’ingénierie du bâtiment repose sur une multitude de notions souvent enseignées séparément : résistance des matériaux, calculs de charges, choix des matériaux, vérification des appuis… Or, la réalité du terrain est tout autre. Les notions s’imbriquent, comme les pièces d’un puzzle : une poutre n’existe pas sans ses appuis, un plancher ne vit pas sans ses murs porteurs, une charge n’a de sens que par son cheminement jusqu’aux fondations.
L’ambition de ce livre est de présenter ces éléments dispersés dans une logique cohérente et progressive, accessible à tous ceux qui interviennent sur un chantier. Pas question ici de bâtiments complexes, aux formes audacieuses et calculs sophistiqués. Les principes et cas concrets présentés s’ancrent dans le chantier courant, celui de nos habitations, des extensions, des transformations et réhabilitations du quotidien. Car ce sont ces ouvrages modestes qui concentrent l’essentiel des erreurs de calcul lorsque les bases ne sont pas maîtrisées.
Cet ouvrage sera une ressource précieuse pour les étudiants et jeunes professionnels soucieux de comprendre les fondamentaux du dimensionnement et de les appliquer avec rigueur et bon sens.
 

Description
Software development today is very different from what it was even a few years ago. Writing clean code is no longer enough when applications run on cloud platforms, scale on demand, and are expected to be available all the time. Developers are increasingly expected to understand how their code behaves in production, how it scales under load, how failures are handled, and how costs are controlled. These expectations make operational thinking a core part of modern development.

This book provides a structured guide for developers transitioning from traditional operations toward NoOps, emphasizing logging, metrics, integrated security, and CI/CD ownership. The technical core covers mastering infrastructure as code with Terraform and orchestrating Kubernetes via Helm charts and canary deployments. After exploring production excellence through Prometheus monitoring, chaos testing, and FinOps cost optimization, the guide concludes with AI-driven automation and real-world case studies from the OTT and gaming industries to prepare you for the future of autonomous development.

By the end of this book, readers will be comfortable taking responsibility beyond just writing features. They will be able to design, deploy, and run services that are reliable, scalable, secure, and cost-efficient, and confidently operate as end-to-end service owners in modern engineering teams.

Comment transformer en profondeur nos modèles industriels pour répondre aux défis environnementaux, sociaux, techniques et économiques du XXI^e siècle ? Face aux impératifs de sobriété, de relocalisation et d’attractivité, l’industrie française doit repenser ses modes d’organisation, ses chaînes de production et sa relation au territoire en s’appuyant sur les derniers progrès de la science en matière de calcul, d’énergie, d’IA.

Pendant trois ans, les laboratoires du Carnot M.I.N.E.S ont conduit un vaste programme de recherche pour accompagner cette mutation. En mobilisant des compétences pluridisciplinaires – des sciences de l’ingénieur aux sciences humaines et sociales –, le projet Industrie responsable a exploré de nouvelles voies pour concilier performance industrielle, responsabilité environnementale et qualité du travail. Ce livre blanc présente les principaux résultats et enseignements de ce projet structurant : innovations méthodologiques, modèles de production plus flexibles et durables, plateformes numériques à forte valeur ajoutée, et reconfiguration des réseaux productifs autour de critères de résilience et de responsabilité.

Destiné aux industriels, chercheurs, décideurs publics et acteurs de l’innovation, cet ouvrage offre une synthèse accessible et prospective des travaux menés au sein du Carnot M.I.N.E.S. Il éclaire les leviers scientifiques et organisationnels d’une industrie plus vertueuse : une industrie capable de conjuguer compétitivité, attractivité et durabilité.

Cet ouvrage éclaire, de manière novatrice, les facteurs cosmiques, évolutifs, climatiques et environnementaux à l’origine du surgissement de la vie, de la complexification du vivant, de l’émergence des formes humaines anciennes et de celle de notre espèce, Homo sapiens. Il explore la fabrique de notre humanité et décrypte les conditions ayant permis à notre espèce d’acquérir un cerveau hors du commun. Enfin, il pose l’hypothèse de l’émergence des premiers sapiens dans un territoire du nord-ouest de l’Afrique, en montrant pourquoi ces lieux auraient constitué notre berceau.

« Un ouvrage fascinant, instructif – indispensable », souligne la paléontologue et historienne des sciences Claudine Cohen.

Certaines plantes semblent tout droit sorties d’un conte, d’autres défient les lois de la nature. Racines aériennes, feuilles géantes, fleurs spectaculaires ou stratégies de survie étonnantes… le monde végétal regorge de curiosités fascinantes. À travers une sélection de plantes remarquables venues des quatre coins du monde, ce livre vous invite à découvrir leurs particularités, leur origine, leurs usages et les histoires étonnantes qui les entourent. Du majestueux banian aux surprenants cycas, en passant par les orchidées ou les protéas, chaque espèce révèle une facette inattendue de la diversité végétale. Illustré de nombreuses photographies, cet ouvrage propose un voyage accessible et captivant au cœur de ces plantes étonnantes, parfois familières, souvent méconnues. Une invitation à regarder la nature autrement… et à s’émerveiller devant l’ingéniosité du monde végétal

Silencieux, méconnus, presqu'invisibles… et pourtant essentiels. En un siècle et demi, les vers de terre sont passés du statut de nuisibles à celui d’alliés de l’agriculture durable et des jardins. Loin d’être un détail naturaliste, la diversité de ces êtres constitue la clé pour comprendre les multiples services qu’ils rendent aux écosystèmes : aération des sols, infiltration de l’eau, recyclage de la matière organique, stimulation de la vie microbienne…

Que mangent-ils ? Sont-ils vraiment capables de creuser jusqu’à 10 mètres sous terre ? Comment les identifier ? Ce livre invite à affiner notre regard sur ces habitants du sol et dévoile les aspects souvent ignorés de leur biologie et de leur écologie afin de mieux les connaître et les préserver. Il propose également une nouvelle manière de les classer en se fondant sur leurs effets directs sur le sol, qui est la fois habitat, source de nourriture et lieu de déplacement. 

Cet ouvrage s’adresse à toutes celles et ceux qui cherchent à mieux connaître ces animaux et veulent comprendre pourquoi ils pourraient bien jouer un rôle majeur dans la durabilité de notre alimentation.

En 2024, 97 % du gaz méthane consommé en France est encore d’origine fossile, importé pour moitié depuis seulement 3 pays : États-Unis, Russie et Algérie. Ce choix énergétique pèse lourd : sur le climat, sur la souveraineté européenne, et sur notre économie, représentant à lui seul 22 % des émissions nationales de gaz à effet de serre et une part semblable de notre déficit commercial.

Face à cette triple impasse, les promesses des gaz dits « verts » peinent à convaincre. Coûteux et dépendants de ressources rares comme la biomasse, leur montée en puissance est limitée et ne suffira pas à remplacer le gaz fossile. La seule issue réaliste ? Réduire notre consommation de gaz, et vite.

Mais comment rendre cette transition possible, désirable et juste ? Ce livre propose plusieurs leviers pragmatiques pour agir sur la consommation et accompagner sa réduction en adaptant l’architecture du réseau et en protégeant les consommateurs les plus vulnérables.

Entre analyse rigoureuse et propositions concrètes, cet ouvrage trace une première feuille de route pour repenser notre rapport au gaz, sortir des illusions, et construire une stratégie énergétique alignée avec les enjeux du XXI^e siècle.
