supercritical fluid 

A supercritical fluid is any substance at a temperature and pressure above its critical point. It can seep through solids like a gas, and dissolve materials like a liquid. plus, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical fluid to be negligable. Supercritical fluids are used as a substitute for organic solvents in a range of industrial and laboratory processes.

Looking Down
Agreeing
Looking Concerned

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
