Cryogenics

Cryogenics is the study of materials and phenomena at extremely low temperatures, typically below -150 degrees Celsius (-238 degrees Fahrenheit). At these temperatures, certain materials can exhibit unique properties, such as superconductivity, where they can conduct electricity without resistance. This enables efficient power transmission and powerful magnetic fields used in technologies like MRI machines and particle accelerators. Cryogenics also plays a vital role in fields such as astrophysics and materials science, where understanding the behavior of substances at low temperatures can lead to innovative applications and advancements in technology.
