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.

Calendar. Distributed Intelligence. Discover Magazine dark matter. Your hands are, roughly speaking, 360 million years old.
Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today.
We know a fair amount about the transition from fins to hands thanks to the moderately mad obsession of paleontologists, who venture to inhospitable places around the Arctic where the best fossils from that period of our evolution are buried. A team of Spanish scientists has provided us with a glimpse of that story. Discover Science Mag. Book Publishers. 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. Electricity and Magnetism. Electricity and Magnetism Timeline of Electricity and Magnetism - Our timeline guides you through the highlights of electricity and magnetism across the globe, from the first compasses in China to the invention of magnetic core computer memory at the Massachusetts Institute of Technology and beyond.
Pioneers in Electricity and Magnetism - Ampere, Celsius, Kelvin, Hertz, Tesla: These terms are familiar to all science students. Behind them is a group of scientists who went down in history for their groundbreaking work in magnetism and electricity. Who were these brilliant inventors, physicists and chemists, and what lasting contributions did they make to their fields – and to our lives? Get to know these pioneers by visiting this section. History of the Compact Disc - During the mid to late 1980's, compact discs began to take over both the audio and computer program market. Science news.
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... What do you get when you suspend nanoparticles of iron compounds in a colloidal solution of water, oil and a surfactant? Did you guess Zima? The real answer is ferrofluids, though you should be proud if you just knew what "surfactant" was. A ferrofluid is a liquid that reacts to magnetic fields in trippy ways that make you think that science is both magical and potentially evil. Tell us that didn't look like the birth of the most sinister dildo ever. What happens is that when a magnetic field is applied to the fluid, the particles of iron compound inside align to it.
