July 25, 2012 - Higgs excitations near absolute zero: The sudden breaking of symmetry plays a fundamental role in physics, in particular for the description of phase transitions that change the whole state of a system. One example is the spontaneous alignment of the atomic magnets in a ferromagnetic material that is cooled down below the Curie-temperature. Being governed by such a “global order”, the system can be excited to a collective oscillation, in which all particles move in a...
A Canadian nickel has the ferromagnetic element nickel as a major part of its composition, and is strongly attracted to a magnet, as shown in the photograph. When heated above its Curie temperature by the gas torch, it loses its ferromagnetism and falls away from the magnet to the pedestal. After a few seconds it will again be pulled up to the magnet.
Tesla's Thermomagnetic Motor - a little known invention of his. Tesla’s thermomagnetic motor is based on the phenomenon known as Curie temperature (after its discoverer, Pierre Curie — of radium fame). The Curie temperature is the point at which permanent magnetic properties of certain metals go down the drain.
Ultra-Cozy Giant Knit Blankets Are Made Without Any Knitting Needles Necessary
As the temperatures continue to dip, it’s prime time for cozy knitwear to take the edge off winter. Last year, we marveled at Ohhio’s ultra-chunky creation
