No Calculators Allowed 

When students’ reliance on a scientific or graphing calculator prevents them from being fluent in performing certain basic operations, such as factorizing a function, finding the zeros of a cubic polynomial, and standardizing a normal distribution from the Statistical Tables—ritually pressing a set of keys often conceals their poor understanding or mastery of these routines.
If only math teachers and tutors would implement the “No Calculators Allowed” rule, students would be manually forced to learn the routine or tedious steps in getting the answer to some intermediate step of a problem.

"Great news! Government Healthcare just passed which should decrease the deficit by about 2 Trillion!!" "ah, I love the Congressional Calculator, I'm gonna go buy a new 'vette."

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.
