A Bose Einstein condensation, a state predicted by Einstein almost a century ago, is the unique state of matter in which certain types of atoms can exist in temperatures close to absolute zero. The Bose Einstein condensate is one of the simplest systems in nature. The Bose Einstein condensation shows the phenomenon of superfluity and superconductivity.Know More
The Bose Einstein condensate is a gas of atoms so dense and cold that their matter waves lose their individuality and condense into a macroscopic coherent superatom wave. Atomic Bose Einstein condensation very often occurs at a temperature near absolute zero. However, excitons are expected to exhibit the same phenomenon at temperatures that are millions of times higher.
Remarkably, this is a range of temperatures whereat Butov and his team have observed the onset of exciton coherence. Excitons are particles that can be created inside of semiconductors -- in this case, gallium arsenide, the material used to make transistors in cell phones. One can make excitons, or excite them, by shining bright light on a semiconductor. The light kicks electrons out of the atomic orbitals they normally occupy inside of the material. This creates a negatively charged "free" electron and a positively charged "hole."Learn more about States of Matter
Albert Einstein is prominently knownÂ forÂ his theories of relativity and for formulating the famousÂ equation E = mc2, where "E" denotes energy, "m" indicates mass and "c" represent the speed of light. Einstein is less noted for his photoelectric law, which won him the Nobel Prize in Physics in 1921.Full Answer >
Albert Einstein was not buried; he was cremated, and the location of his ashes is unknown. Einstein died in 1955 at a New Jersey hospital at the age of 76. The cause was internal bleeding, stemming from a burst aneurysm.Full Answer >
Albert Einstein was born on March 14, 1879, and died 76 years later, on April 18, 1955. He is best remembered for his groundbreaking work on the general theory of relativity and the famous equation E = mc2.Full Answer >
Different types of plastics have drastically different melting points, which means some plastics such as polyvinyl chloride plastics can melt at as low as 165 degrees Fahrenheit, while other types such as the plastic in Teflon cookware will not melt until they reach temperatures of around 600 degrees or hotter. Most sturdy plastics will melt before 500 degrees.Full Answer >
