The world's biggest magnet is, in fact, the Earth. The Earth's solid iron-nickel inner core spinning in the liquid iron-nickel outer core behaves like a dynamo, generating a magnetic field. The weak magnetic field acts like a bar magnet tilted at about 11 degrees from the Earth's axis...
The interactive online simulation is a new technology for teaching physics. The physics education technology project (phet.colorado.edu) has developed about 50 sophisticated simulations that are run through a regular browser and are avai...

in the simulation below (created by michael dubson and the folks at phet interactive simulations / university of colorado). you should see a planet orbiting the sun. now press 'reset', and drag the circle with the letter 'v' to shrink the planet's speed . then press 'start' again. ...
Design and simulation of an X-band solid state power amplifier The chip area, including pads, is as small as 0.81 [mm.sup.2], which is relatively compact among published pHEMT mixers. A compact double-balanced star mixer with novel dual 180[degrees] hybrid RFMD's advanced GaAs pHEMT techno...
whereby more attention is paid to a recently presented stimulus than to a non-recent stimulus.47Thus for these mice the stimulus is treated as even more salient or intense the second time it is presented. Deficits in short-term habituation therefore represent a potential driver of aberrant salien...
