Latest Kelvin Stories
Scientists at the UK's National Physical Laboratory (NPL) have performed the most accurate measurement yet of the Boltzmann constant.
Metrologists are measurement artists who are very precise - in the case of the Boltzmann constant up to the sixth decimal place.
Imagine building a car chassis without a blueprint or even a list of recommended construction materials.
Physicists at the University of California-San Diego say they've created speedy integrated computer circuits capable of working in very cold environments. The circuits, built with particles called excitons, can operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality, researchers said. The accomplishment follows the team's demonstration last summer of an integrated circuit capable of working at 1.5 degrees...
Physicists at UC San Diego have successfully created speedy integrated circuits with particles called â€œexcitonsâ€ that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.
- A handkerchief.
- Specifically— The legendary sweat-cloth; the handkerchief of St. Veronica, according to tradition miraculously impressed with the mask of Christ; also, the napkin about Christ's head (Johu xx. 7).
- In general, any miraculous portrait of Christ.
