Beautiful Watercolor Paintings of Architecture by Thomas W. Schaller "Don't paint the scene in front of you. Paint the light that defines it and gives it life." Though he was raised on a farm in the Midwest, Thomas W. Schaller spent the majority of his life in Manhattan where he worked as a commercial architectural artist. That day, Schaller's life changed. "That said, I did build up a wealth of technical skills upon which I can draw - perspective, scale, composition, etc, - that have become almost a kind of 'muscle memory' for me as a painter. Schaller doesn't just paint buildings, rarely are they seen as isolated subjects. As for his creative process, Schaller prefers to complete each work all at one time, rarely does he allow anything to be completely dry before he moves on to the next part. When we asked him what he hoped others got out of his work, Schaller told us, "Most all my work is informed by real world observation but I never paint exactly what I see.
La turbulence | Canal U Cinq siècles après les travaux de Léonard de Vinci sur le contrôle des tourbillons et de leur effet dans la rivière Arno, le sujet n'est toujours pas clos. Au XXème siècle ce sont d'abord les innombrables applications pratiques (par exemple dans le domaine de l'aéronautique) qui ont été le moteur d'un progrès qui se concrétisait plutôt par le développement de modèles empiriques que par de véritables percées fondamentales. A partir de 1940, grâce en particulier au mathématicien russe Andrei Nikolaevich Kolmogorov, une véritable théorie a été proposée.
From Michelangelo to Caravaggio, why masterpieces are coming out of the woodwork | Art and design The attribution of two bronze nudes to none other than Michelangelo is one of those rare art stories that are genuinely important and authentically sensational. And like so many truly significant art history discoveries, this one does not involve digging a lost masterpiece out of a cellar or finding it in a Nazi hoard, but is instead a scholarly argument for re-attributing a work known for centuries. A lot of the time, this kind of connoisseurship leads to the opposite: sceptical de-attribution. Paul Joannides, the art historian whose immense knowledge lends the Cambridge claim authority, put some of the final nails into the reputation of the Venetian painter Giorgione when he all but demolished the idea that Giorgione painted the Sleeping Venus, one of the icons of the Renaissance. He and others argue it is by Titian. One hundred and fifty years ago, there were lots more Giorgiones, Leonardos and other masterpieces by big-name artists than there are today.

Michelangelo bronzes discovered | Art and design Two handsome, virile naked men riding triumphantly on ferocious panthers will on Monday be unveiled as, probably, the only surviving bronze sculptures by the Renaissance giant Michelangelo. In art history terms, the attribution is sensational. Academics in Cambridge will suggest that a pair of mysterious metre-high sculptures known as the Rothschild Bronzes are by the master himself, made just after he completed David and as he was about to embark on the Sistine Chapel ceiling. If correct, they are the only surviving Michelangelo bronzes in the world. They will go on public display at the Fitzwilliam Museum in Cambridge from Tuesday. Victoria Avery, keeper of applied arts at the museum, said the attribution project, involving an international team of experts from different fields, had been like “a Renaissance whodunnit”. Last autumn, Paul Joannides, professor of art history at Cambridge University, connected the sculptures to the drawing. “They are clearly masterpieces,” said Avery.
Turbulence MHD MHD turbulence describes turbulence in an electrically conducting, magnetized fluid (Biskamp 2003). Strictly speaking, MHD only applies to collision dominated fluids. However, it is often a useful guide to the behavior of magnetized plasmas even in the collisionless limit. Nature routinely produces MHD turbulence. The evolution of a weak magnetic field in isotropic MHD turbulence poses an interesting problem. A short article cannot adequately cover all aspects of MHD turbulence. Incompressible MHD Turbulence Incompressible MHD is described by two solenoidal vector fields, the velocity, and the magnetic intensity, These must simultaneously satisfy the Navier Stokes and induction equations. and propagate with group velocity, either parallel or antiparallel to depending upon the sign of Three properties of incompressible MHD form the bulwark of current models of MHD turbulence. with The third is a consequence of the separate conservation of energy and cross helicity Steady-State Cascades
Form Matters: Wearable Concrete Jewelry Concrete is a pretty amazing material. Form Matters explores the dual nature of concrete — of how it can be used to create architectural masterpieces meant to last hundreds of years to wearable, everyday accessories. It examines the overlapping nature of architecture, art, and fashion. Designed by Liani Douglas for Douglas & Company, the accessories consist of simple lines with subtle tension. Their subtle geometric forms are reminiscent of architectural pieces, such as concrete pipes and culverts, but with a cantilevered plane. The bracelets are a concrete mix of 40% sand and 60% Portland cement and water.
