The Spanish Prisoner scam—and its modern variant, the advance-fee scam or "Nigerian letter scam"—involves enlisting the mark to aid in retrieving some stolen money from its hiding place. The victim sometimes believes they can cheat the con artists out of their money, but anyone trying this has already fallen for the essential con by ...

To allow mid-infrared observations within the JWST, the MIRI instrument has an additional cooling system. It works roughly similar to how most refrigerators or an air-conditioner works: a fluid is brought down to a cold temperature in the warm section, and sent back to the cold section where it absorbs heat, then it goes back to the condenser.
Originally this was considered to be impossible. For some time it looked as if it would be impossible to cool below the lambda point of 4 He (2.17 K), but the low-temperature group of the Eindhoven University of Technology managed to cool to a temperature of 1.73 K by replacing the usual 4 He as refrigerant by its rare isotope 3 He.
A British multinational design and engineering company behind world-famous buildings such as the Sydney Opera House has confirmed that it was the target of a deepfake scam that led to one of its ...
Nitrogen is a liquid under −195.8 °C (77.3 K).. In physics, cryogenics is the production and behaviour of materials at very low temperatures.. The 13th International Institute of Refrigeration's (IIR) International Congress of Refrigeration (held in Washington DC in 1971) endorsed a universal definition of "cryogenics" and "cryogenic" by accepting a threshold of 120 K (−153 °C) to ...
The mid-infrared, approximately 4,000–400 cm −1 (2.5–25 μm) is generally used to study the fundamental vibrations and associated rotational–vibrational structure. The far-infrared, approximately 400–10 cm −1 (25–1,000 μm) has low energy and may be used for rotational spectroscopy and low frequency
A refrigerator designed to reach cryogenic temperatures (below 120 K, -153 °C, -243.4 °F) is often called a cryocooler.The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW.
