Matrix mechanics Matrix mechanics is a formulation of quantum mechanics created by Werner Heisenberg, Max Born, and Pascual Jordan in 1925. Matrix mechanics was the first conceptually autonomous and logically consistent formulation of quantum mechanics. It extended the Bohr Model by describing how the quantum jumps occur. It did so by interpreting the physical properties of particles as matrices that evolve in time. It is equivalent to the Schrödinger wave formulation of quantum mechanics, and is the basis of Dirac's bra-ket notation for the wave function. PDB Newsletter Biomedical animator Drew Berry ( Walter and Eliza Hall Institute of Medical Research ) is known for his fantastic and detailed depictions of complex biomolecular systems. His award-winning work, which can be viewed online, in television and film, and in museums throughout the world, now appears in new and unusual venues thanks to a collaboration with the musician Björk. Björk's latest project Biophilia manifests her love for music, technology, and nature in many ways: an album, iPad app, touring production (which includes a 24-woman Icelandic choir and a musical Tesla coil), and a music education initiative.

Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land.

Scientific Photography Scientific photography is about visualizing things that can't be seen with the unaided eye. It is used to describe natural and man-made phenomena in a way that clarifies, educates, and illuminates. Through scientific photography, we can describe things to other scientists, but also to the public, which in many cases supports the research with its tax money. Science photography that is beautiful and otherwise aesthetically pleasing is able to capture the imagination of the viewer to a degree unlike any other style of photography. Something about images of things never scene before: witness the fascination with the remarkable space photographs brought back by the Hubble telescope. Scientific photographs address a deep human need to explore, to push frontiers, and to answer fundamental questions about the world around us.
7 Man-Made Substances that Laugh in the Face of Physics The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive. But mankind isn't happy to accept the weirdness of nature when we can create our own abominations of science that, due to the miracle of technology, spit in nature's face and call it retarded. That's why we came up with... #7. Ferrofluids Science Photography Spotlight On January 7, 1839, an installation artist and chemist named Louis-Jacques-Mandé Daguerre announced to the French Academy of Sciences in Paris that he had perfected a photographic imaging technology that could be used on a large scale and was reproducible. His invention, later named the daguerreotype, was based on a special property of silver iodide: when exposed to light, the molecules undergo a chemical transformation that can be turned into charcoal-colored shadows and lines when later exposed to developing mercury fumes. The more intense the light, the darker the resulting silver-mercury amalgam. When a sheet of metal copper coated with silver iodide, for instance, was exposed to a street scene for a prolonged period, an image of the street was represented on the daguerreotype plate as lines and shadows of varying brightness. Daguerre initially thought his invention would be suitable mostly for personal use in travel logs, art installations, and architectural records.
Electric Weather The following excerpts come from a report that appeared in the Institute of Electrical and Electronics Engineers (IEEE) magazine, SPECTRUM, for April. The report demonstrates that when science has lost its way, engineers must use their intuition to make progress. Electric Rainmaking Technology Gets Mexico’s BlessingBut for now, doubters prevail north of the border.From at least the early 1940′s to the end of the 20th century, it always rained more in the state of Jalisco, in central Mexico, than in its neighbor Aguascalientes. But in 2000, on a patch of parched pasture in Aguascalientes, workers from Mexico City-based Electrificación Local de la Atmósfera Terrestre SA (ELAT) erected a peculiar field of interconnected metal poles and wires somewhat resembling the skeleton of a carnival tent.
Special Report - International Science and Engineering Visualization Challenge Thank you for your interest in the International Science & Engineering Visualization Challenge. We are in the process of restructuring the Visualization Challenge. We will begin accepting entries in September 2014. Please visit this site periodically for updates. Some of science's most powerful statements are not made in words. From DaVinci's Vitruvian Man to Rosalind Franklin's X-rays, science visualization has a long and literally illustrious history. Compound Eye: the many facets of science photography A compound eye is a visual sensory organ composed of numerous small lenses. This charming South American grasshopper sports an especially large pair. Welcome to Compound Eye, a Scientific American photography blog!
