Amazing Scanning Electron Microscope Photos All these pictures are from the book 'Microcosmos,' created by Brandon Brill from London. This book includes many scanning electron microscope (SEM) images of insects, human body parts and household items. These are the most amazing images of what is too small to see with the naked eye. 2-2-11 An ant, Formica fusca , holding a microchip Surface of an Erasable Programmable Read-Only Memory silicon microchip Eyelash hairs growing from the surface of human skin
Amazing Scanning Electron Microscope Photos
Here is a 3D view of a hydrogren atom in the 4f state. The left image was made in C++ using a technique described by Krzysztof Marczak to make it volumetric like a cloud of smoke. The right image was made in Mathematica by adding 2D cross-sectional layers.

La théorie des perturbations est un outil extrêmement pratique dans le calcul des probabilités des interactions dites faibles, dans un cadre classique (non relativiste). Par contre, lorsque l'on inclut à ce type d'interaction des particules fortement relativistes, cette théorie procure des résultats beaucoup trop compliqués à calculer, d'où l'intérêt de développer un nouvel outil permettant d'appliquer cette théorie des perturbations aux cas relativistes. Cet outil porte aujourd’hui le nom de diagramme de Feynman. Bien qu'ils permettent de visualiser les interactions entre les particules, les diagrammes de Feynman sont bien plus qu'une simple représentation schématique. Le but premier de cet outil est de réduire – considérablement - les calculs décrivant ces interactions en les réduisant à de simples variations d’amplitude de probabilité.

The EMMA ring in relation to the main ERLP (ALICE) accelerator. (PhysOrg.com) -- Researchers at Daresbury science park in Britain have offered a glimpse into what might be the future of nuclear energy production by showcasing a scaled down particle accelerator; one, that when combined with others just like it, could produce nuclear energy based on thorium, rather than uranium. Dubbed the Electron Machine with Many Applications (EMMA), the accelerator, a much smaller version of the kind used in physics research, such as the Large Hadron Collider, could be used to provide an accelerated beam necessary for the type of nuclear reaction used in a theoretical thorium plant. Thorium, named for the Norse god of thunder, is a silver-white metal found in abundance all over the planet, and is only very slightly radioactive and as such is a member of the elements known as actinides which, like uranium, occasionally spin off particles which make it useful for energy production.
