Смысл: The text aims to demonstrate the Meissner effect (quantum levitation) using a university video, explaining that while visually impressive, it currently requires extreme cooling to function.
A short post showcasing the Meissner effect via a Tel Aviv University video and explaining the need for room-temperature superconductors for practical use.
Смысл: The text reports a 2009 record in superconductivity achieved at -19°C (254K), explaining that this allows the phenomenon of zero electrical resistance and magnetic levitation to be observed at temperatures found in common refrigerators, which is crucial for efficient high-power magnetic fields.
A scientific breakthrough in 2009 achieved superconductivity at -19°C, making magnetic levitation accessible at domestic refrigerator temperatures.
Смысл: The main idea is to report on a NASA experiment where a superconducting magnet was used to achieve the magnetic levitation of a mouse, demonstrating the ability to lift larger biological organisms through the interaction of magnetic fields with ions in the body.
NASA researchers successfully used a powerful superconducting magnet to levitate a mouse by interacting with the minerals in its blood.
