		<description>&lt;p&gt;Cet article explore la dynamique entre cr&#233;ativit&#233; humaine et cr&#233;ativit&#233; artificielle, en s'appuyant sur une ap-proche personnelle &#224; la crois&#233;e de l'art et de la science, ainsi que sur le projet &#8220;Titan 2358&#8221;, une oeuvre hybride combi-nant art, science-fiction, histoire, philosophie et intelligence artificielle. La cr&#233;ativit&#233; humaine est analys&#233;e &#224; travers les cadres th&#233;oriques de Margaret Boden (Nouveaut&#233;, Surprise, Valeur et Combinatoire, Exploratoire, Transformationnelle) et de Mark A. Runco (Personne, Processus, Produit, Potentiel). La Cr&#233;ativit&#233; Artificielle (AC, un concept forg&#233; par Runco) est analys&#233;e par une intelligence artificielle en r&#233;ponse &#224; un tr&#232;s long &#171; prompt &#187; &#233;crit d'apr&#232;s des recherches de l'auteur. Trois visions sont compar&#233;es concernant l'AC en g&#233;n&#233;ral (c'est possible, ce n'est pas encore possible, c'est impossible). La discussion commente cette analyse et essaie d'expliquer pourquoi l'AC est impossible en utilisant la th&#233;orie d'Antonio Damasio qui souligne l'importance des affects, des &#233;motions, des sentiments, de la conscience et de l'hom&#233;ostasie dans le processus cr&#233;atif. Ray Kurzweil contredit ce point de vue et affirme que les ordinateurs sont, ou seront bient&#244;t, bien plus intelligents et cr&#233;atifs que les humains. Mais un ordinateur peut-il d&#233;cider de cr&#233;er de l'art pour plaire &#224; d'autres ordi-nateurs ou pour augmenter ses chances de survie ? Est-ce que l'AC peut &#234;tre un outil r&#233;volutionnaire pour les artistes, tout comme le fut la photographie &#224; une certaine &#233;poque ? En annexe, une conversation entre l'auteur et l'IA fournit des perspectives int&#233;ressantes sur la cr&#233;ativit&#233; humaine par rapport &#224; la cr&#233;ativit&#233; artificielle.&lt;/p&gt;

		<description>&lt;p&gt;This paper explores the dynamics between human creativity and artificial creativity, drawing on a personal approach at the crossroads of art and science, as well as on the Titan 2358 project, a hybrid work combining art, science, fiction, history, philosophy and artificial intelligence. Human creativity is analysed through the theoretical frameworks of Margaret Boden (Novelty, Surprise, Value and Combinational, Exploratory, Transformational) and Mark A. Runco (the four Ps: Person, Process, Product, Potential). Artificial Creativity (a concept forged by Runco) is analysed by an Artificial Intelligence in response to a very lengthy prompt written after researches by the author. Three visions are compared con-cerning AC in general (it is possible, it is not yet possible, it is impossible). The discussion comments on that analysis and tries to explain why AC is impossible using the theory of Antonio Damasio who highlight the importance of affects, emo-tions, sentiments, consciousness and homeostasis in the creative process. Ray Kurzweil contradicts this point of view and affirms that computers are, or soon will be, far more intelligent and creative than humans. But can a computer decide to create art to please other computers or to increase its chance of survival? Can AC be a revolutionary tool for artists, just as photography was at one time? In appendix a conversation between the author and the AI provides some interesting insights on the Human versus Artificial creativity.&lt;/p&gt;

		<description>&lt;p&gt;En 1859, l'Origine des Esp&#232;ces' de Darwin a provoqu&#233; une r&#233;volution en biologie en offrant une explication &#224; l'immense diversit&#233; des formes de vie. Toutefois, il n'expliquait pas l'origine de la vie sur Terre et n'&#233;voquait aucune forme de vie primordiale susceptible d'avoir donn&#233; naissance aux esp&#232;ces actuelles. Deux des plus fervents disciples de Darwin, Thomas Huxley et Ernst Haeckel, crurent avoir trouv&#233; une r&#233;ponse gr&#226;ce &#224; la d&#233;couverte, faite par Huxley en 1868, d'un micro-organisme qu'il baptisa Bathybius haeckelii. Selon Huxley, il s'agissait des masses g&#233;latineuse d&#233;pourvue de structure distincte tapissant les fonds marins ; pour Haeckel, elles r&#233;sultait vraisemblablement d'une g&#233;n&#233;ration spontan&#233;e. Bien que largement salu&#233;e, cette d&#233;couverte fut de courte dur&#233;e : en 1875, il fut &#233;tabli que ces masses g&#233;latineuses, observ&#233;es dans des &#233;chantillons de boue abyssale, n'&#233;taient en r&#233;alit&#233; qu'un artefact li&#233; &#224; la conservation des pr&#233;l&#232;vements. L'hypoth&#232;se avanc&#233;e ici est que le Bathybius fut accept&#233;, ne serait-ce que pour quelques ann&#233;es, non seulement parce qu'il comblait une lacune per&#231;ue dans la th&#233;orie de Darwin, mais aussi, en grande partie, gr&#226;ce aux illustrations de Haeckel le repr&#233;sentant comme une cr&#233;ature vivante ; c'est ce que montre la biographie illustr&#233; du Bathybius pr&#233;sent&#233;e ici.&lt;/p&gt;

		<dc:subject>Thomas Huxley</dc:subject>
		<dc:subject>Ernst Haeckel</dc:subject>
		<dc:subject>Origin of Life</dc:subject>
		<dc:subject>Scientific Illustration</dc:subject>

		<description>&lt;p&gt;In 1859, Darwin's Origin of the Species provoked a revolution in biology, providing an explanation for the tremendous diversity of life forms. However, it had no explanation of how life originated on earth, nor discussion of a primordial life form that would give rise to existing life forms. Two of Darwin's most devoted followers, Thomas Huxley and Ernst Haeckel, believed a solution had been found in the form Huxley's discovery in 1868 of a microorganism he christened, Bathybius Haeckelii. It was a featureless gelatinous masse, covering the floor of the deep sea, according to Huxley, and plausibly formed by spontaneous generation, according to Haeckel. Although widely heralded, it was short-lived as gelatinous masses found in samples of deep-sea mud were found to be an artifact of sample preservation in 1875. Here the view put forward is that Bathybius was accepted, if only for a few years, not only because it filled a perceived lack in Darwin's theory, but also due in large part to Haeckel's illustrations of Bathybius as life-like creature, shown here through a pictorial biography of Bathybius.&lt;/p&gt;

		<description>&lt;p&gt;Quelle relation existe-t-il entre l'&#233;tendue mat&#233;rielle d'une couleur et l'effet qu'elle produit dans l'organisation perceptive d'un dessin ? Cet article examine cette question &#224; partir d'une situation rencontr&#233;e dans ma pratique : une quantit&#233; tr&#232;s r&#233;duite de jaune modifie sensiblement l'&#233;quilibre que je per&#231;ois dans l 'ensemble d'un dessin. Cette observation devient le point de d&#233;part d 'une investigation conduite par la pratique. L'ajout, le retrait, la r&#233;duction puis le d&#233;placement du jaune constituent une succession d'op&#233;rations permettant d'observer les variations de son action perceptive. L'exp&#233;rience est mise en relation avec les recherches consacr&#233;es &#224; la d&#233;pendance contextuelle de la perception chromatique et &#224; l 'induction chromatique, ainsi qu'avec l'approche exp&#233;rimentale de Josef Albers. Elle n'est pas pr&#233;sent&#233;e comme une exp&#233;rience psychophysique et ne permet aucune g&#233;n&#233;ralisation &#224; d'autres observateurs. Elle permet en revanche d'examiner comment un ph&#233;nom&#232;ne perceptif devient, au cours m&#234;me du dessin, un instrument de d&#233;cision et de connaissance. L'hypoth&#232;se explor&#233;e est que la pratique graphique peut produire une connaissance situ&#233;e de la perception lorsqu'elle rend observables les relations entre transformation mat&#233;rielle, attention et d&#233;cision qui accompagnent la construction d'une image.&lt;/p&gt;

		<description>&lt;p&gt;What is the relationship between the physical extent of a colour and the effect it produces on the perceptual organization of a drawing? This article examines this question through a situation encountered in my own practice: a very small amount of yellow noticeably alters the balance I perceive within a drawing as a whole. This observation becomes the starting point for a practice-based investigation. Adding, removing, reducing and then relocating the yellow constitute a sequence of operations through which variations in its perceptual action can be observed. he experience is considered in relation to research on the contextual dependence of colour perception and chromatic induction, as well as Josef Albers's experimental approach to colour. It is not presented as a psychophysical experiment and does not allo generalization to other observers. Rather, it provides an opportunity to examine how a perceptual phenomenon can become, within the drawing process itself, an instrument of decision-making and knowledge. The hypothesis explored here is that drawing practice can produce situated knowledge of perception when it makes observable the relationships between material transformation, attention and decision-making involved in the construction of an image.&lt;/p&gt;

		<description>&lt;p&gt;Cet article analyse les d&#233;terminants ainsi que les compl&#233;mentarit&#233;s existant entre les innovations de produit et de proc&#233;d&#233;. La m&#233;thodologie repose sur un mod&#232;le Probit Bivari&#233;, estim&#233; &#224; partir d'un &#233;chantillon de 603 entreprises formelles s&#233;n&#233;galaises hors secteur agricole. L'unique facteur exer&#231;ant une influence conjointe sur l'adoption des innovations de produits et de proc&#233;d&#233;s est l'utilisation des technologies de l'information et de la communication (TIC), notamment par la possession d'un site web. La performance organisationnelle et la localisation &#224; Dakar exercent une influence significative exclusivement sur l'adoption des innovations de produit. En revanche, l'intensit&#233; concurrentielle et la localisation g&#233;ographique septentrionale exercent une influence exclusive sur l'adoption des innovations de proc&#233;d&#233;. N&#233;anmoins, une compl&#233;mentarit&#233; est observ&#233;e entre les deux cat&#233;gories d'innovation.&lt;/p&gt;

		<description>&lt;p&gt;This article examines the factors and synergies between product innovations and process innovations. This study used a Bivariate Probit model, calculated based on a sample of 603 formal enterprises in Senegal, excluding the agricultural sector. The only variable jointly affecting the adoption of product and process innovations is the utilization of information and communication technology (ICT), namely through website ownership. The performance and location in Dakar significantly influence exclusively the adoption of product innovations. On the other hand, competitive intensity and northern geographical location exert an exclusive influence on the adoption of process innovations. Nevertheless, a complementarity is observed between the two categories of innovations.&lt;/p&gt;

		<description>&lt;p&gt;The Hosoya index of a graph $$$G$$$ is defined as the total number of matchings in $$$G$$$, including the empty edge set. In this paper, we study the maximum value of the Hosoya index. To this end, we introduce the notion of a &#034;balanced forest of stars&#034; and we characterize all forests of size $$$n$$$ and matching number $$$m$$$ that maximize the Hosoya index. We prove that this maximum is attained if and only if the forest is a balanced forest of stars.&lt;/p&gt;
