The fircle is a square-like shape, but with rounded edges. It can also be described as a circle with sides. A fircle is very similar, but not the same as, a squircle.

The formula for calculating the perimeter of a fircle whose four sides have length 'L' is
P = 4L - (8-2π)r

The formula for area would be
A = LW - (4-π)r2

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.
