    Ce este fizica cuantică? Este fizica ce descrie lumea ciudată a atomilor și a particulelor elementare. Uite, tu ești acum în fața ecranului de telefon și nu în altă parte. Un electron însă, este în același timp în toate locurile din atom! Numim asta superpoziție cuantică. Este ca și cum tu ai fi acum atât la București, cât și la New York sau pe Coasta de Azur, toate în același timp! Electronul chiar face asta în vacanțele sale din interiorul atomului, iar fizica cuantică descrie ce proprietăți ciudate au astfel atomii. Unii din care și tu ești făcut! Te întrebi?

    NASA conducts spin test on15-foot-wide saucer-shaped Low-Density Supersonic Decelerator (LDSD)

    NASA’s Low-Density Supersonic Decelerator (LDSD) project will be flying a rocket-powered, saucer-shaped test vehicle into near-space from the Navy’s Pacific Missile Range Facility this June from Kauai, Hawaii. To prepare for the flight, a “spin” test was conducted from the gallery above a clean room at NASA’s Jet Propulsion Laboratory in Pasadena, California, where this near-space experimental test vehicle is being prepared for shipment to Hawaii. During the broadcast, the 15-foot-wide, 7,000-pound vehicle underwent a “spin-table” test. The LDSD crosscutting demonstration mission will test breakthrough technologies that will enable large payloads to be safely landed on the surface of Mars, or other planetary bodies with atmospheres, including Earth.

    Spin Art – Is Black Really Black – Sick Science! #107

    What color is black? Some people answer with a simple “black,” while others respond with something like “black is the absence of all color.” If you have ever run out of black paint or your black pen ran dry, you probably know how to make the color black. Mix a little blue with red and yellow and green and orange and purple and you finally make the color black. Do the people who make black pens mix different colors to make black? Using a technique called chromatography, let’s find out exactly what makes up the color in that black pen.

  • Ice Skating Spin – Cool Science Demo

    Ice Skating Spin – Cool Science Demo

    Check out this and other cool science experiments at http://www.stevespanglerscience.com/experiments/ Ice skaters are not only talented on the ice, but they also have a great understanding of physics as the jump, twist and spin. If you’ve ever seen seen an ice skater start to spin slowly on the tip of their skate and then speed up into an incredible blur of a spin, the secret is pure science. The best part is that you don’t have to be on the ice to test out the science behind the spin. Find an office chair that spins easily and a few weights and you’re ready to make yourself dizzy sick. But it’s all in the name of science.
