How Aboriginal traditions describe the complex motions of planets. The five planets we can see by naked eye were known to the ancient Greeks as “asteres planetai”, meaning “wandering stars”, due to their wandering journey across the sky relative to the fixed stars.

Stuff in Space. Uses or Simple Applications of Electromagnetism in Technology and Life. Written by: sriram balu • edited by: Swagatam • updated: 12/1/2011 Electromagnetism has created a revolution not only in the field of engineering, but also in various other fields like medicine, space, construction etc.

Uses or Simple Applications of Electromagnetism in Technology and Life

Read here to know about various uses of electromagnetism in everyday life from household appliances to research labs. What is RFID? RFID stands for Radio Frequency IDentification, a technology that uses tiny computer chips smaller than a grain of sand to track items at a distance.

What is RFID?

RFID "spy chips" have been hidden in the packaging of Gillette razor products and in other products you might buy at a local Wal-Mart, Target, or Tesco - and they are already being used to spy on people. Facts About Maglev. Magnetic levitation transport, or maglev, is a modern form of transportation that suspends, guides and propels vehicles (especially trains) via electromagnetic force.

Facts About Maglev

This High-Tech method can be significantly faster than wheeled mass transit systems, potentially reaching velocities comparable to turboprop and jet aircraft (550 to 700 km/h) in regular service. Maglev systems represent a revolutionary transport innovation. At the same time, they can also function as a technology development platform (e.g., superconductors, new materials). They can, in certain cases, bring positive economic benefits through the optimization of spatial networking, travel time reduction and resource efficiency.

News - NASA Space Telescopes Provide a 3D Journey Through the Orion Nebula. Astronomers and visualization specialists from NASA’s Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region.

News - NASA Space Telescopes Provide a 3D Journey Through the Orion Nebula

Viewers experience this nearby stellar nursery “close up and personally” as the new digital visualization ferries them among newborn stars, glowing clouds heated by intense radiation, and tadpole-shaped gaseous envelopes surrounding protoplanetary disks. Using actual scientific imagery and other data, combined with Hollywood techniques, a team at the Space Telescope Science Institute in Baltimore, Maryland, and the Caltech/IPAC in Pasadena, California, has created the best and most detailed multi-wavelength visualization yet of this photogenic nebula.

What causes lift? Yesterday, I wrote about one of my favorite kinds of clouds: Kelvin-Helmholtz clouds, also called fluctus clouds.

What causes lift?

You can call them wave clouds, because that’s what they look like: Waves breaking over a beach. I also embedded a video from Sixty Symbols explaining them, but during that explanation the scientist, Mike Merrifield, made a bit of a flub: He said that with an airplane wing, lift is generated because air is moving faster over the top of the wing than the bottom.
