CRYOGENICS. Cryogenics is essential for superconductivity. This reliance of superconductivity on cryogenics has been a major hindrance to the widespread use of superconductivity for applications such as electric power. It is, however, important to put cryogenics in perspective and not overemphasize its role. From cryogenics alone, it is …
