Quantum Un article de Wikipédia, l'encyclopédie libre. En physique, quantum (mot latin signifiant « combien » et dont le pluriel s'écrit « quanta[1] ») représente la plus petite mesure indivisible, que ce soit celle de l'énergie, de la quantité de mouvement ou de la masse. Cette notion est centrale en théorie des quanta, laquelle a donné naissance à la mécanique quantique. Description[modifier | modifier le code] La théorie des quanta ou théorie quantique, affirme que l'énergie rayonnante est discontinue. Ainsi, on peut déterminer facilement l'énergie contenue dans un photon en multipliant sa fréquence (déduite de sa longueur d'onde puisque sa vitesse est constante) par h. La valeur de h est faible : 6,626.10-34 J.s. Et , c'est-à-dire que le quotient est toujours un multiple de h. Histoire[modifier | modifier le code] En physique classique, on considérait que les passages d'un état à un autre se faisaient de manière continue, ou, pour parler autrement, de manière progressive. avec Portail de la physique
Qu’est-ce que le LIGHT PAINTING ? Image 19 sept Comme son nom l’indique, le light painting, c’est du dessin avec de la lumière ! Pour les non-anglophones : « light » signifie « lumière », et « painting », « peinture ». L’idée est donc bien de « peindre une toile », et pour cela, on utilise un pinceau ! Sauf que pour le light painting, on opère avec du matériel photographique. On parlera donc plutôt de « faire des mouvements » devant un décor, muni d’une source lumineuse… // Et un peu de vidéo // Immaterials: Light painting WiFi by Timo Light-Paint Piano Player by Ryan Cashman Light Painting Movie WWF Earth Hour – 2011 (Russian) Pour finir MA best one :) Like this: J'aime chargement… Tags:art, diz iz newz, light painting, lightpainting, photo, photografy, photographie, technik, technique

[RENCONTRE] Guillaume Mazille et Marie Schneider, Les Photographes de l’impossible [1/2] - Blog Photo et Vidéo HDSLR // Obturations.com par Merwen BA J’ai eu la chance de rencontrer, le temps d’une soirée, un jeune couple de photographes hors du commun. Leur passion pour la nature et la photographie les pousse à traverser montagnes, forêts et océans à la recherche de l’extraordinaire. Les photographes de nature m’ont toujours passionné et inspiré. Depuis plus de 10 ans, Guillaume et Marie ont donc parcouru une partie du globe pour observer la nature et dénicher des comportements animaliers incroyables. Ces amoureux de la nature travaillent seuls et un peu à l’ancienne : « On veut montrer qu’avec de petits moyens on peut faire de grandes choses. Dans les deux articles qui vont suivre, je vais donc exposer quelques travaux effectués par ce couple d’aventuriers. Nuit torride chez les grenouilles (Guyane). Le couple a passé deux ans dans ce département français, afin d’observer un comportement de grenouilles rarement photographié. En effet, chaque année, et exclusivement une seule nuit par an, 4 espèces de grenouilles se reproduisent.

AHAE It is the natural world in all its vibrant purity that breathes through the artworks of the Korean photographer Ahae. In his attempt to capture the passing of time and the beauty of his surroundings, Ahae has produced a strong message regarding the responsibility we have towards the world in which we live. His photographs explore the natural environment, which he has worked to protect since the 1970s. He can be described as an inventor, entrepreneur, philanthropist, environmental activist, martial artist, painter, sculptor, poet, and photographer. Ahae’s name is linked with international organic farming and nature conservation projects, and his photographic works became a logical progression from his focus on nature and how we perceive it. Ahae’s creative talent manifested itself from an early age. It was during the 1970s that Ahae first became active in the photographic field; he started collecting cameras and taking photographs, and this continued through the 80s.
