## If My Calculations Are Right…

*“If my calculations are correct, when this baby hits eighty-eight miles per hour–you’re gonna see some serious shit.”*

— Doc Brown, **Back to the Future**, (1985)

You wanna know the greatest thing about the “If my calculations are correct” trope? The greatest thing about “If my calculations are correct” is that it’s not a figment of the pop-culture imagination, doesn’t just come out of the mouths of movie/comic book/sci-fi novel mad scientists. No; actual researchers, making actual calculations, actually say it. To wit:

*“So, e.g., Ts true utility at ai equals (a;i^-4/5).(a;i2, + l). If my calculations are correct, these alphas satisfy Condition A.”*

— Leonid Hurwicz, **Implementation with unknown endowments in a two-trader pure exchange economy**, (2006)

*“The bottom line, if my calculations are correct, is that successful repair was achieved in 60% of the 495 patients.”*

— WIlliam G. Williams, comment on **Early and long-term results of the surgical treatment of tetralogy of Fallot with pulmonary atresia, with or without major aortopulmonary collateral arteries**, (2002).

* “If my calculations are correct, there are exactly 4 atomic fibre germs in genus 3:*

(0) F is an irreducible curve with a single node, and is nonhyperelliptic;

(1) F is a nonsingular hyperelliptic curve;

(2) F = E + C where E and C are irreducible curves of respective genus 1 and 2 meeting transversally in a point Q;

(3) F = 2C where C is a nonsingular genus 2 curve, and OC(C) is a nonzero 2-torsion class.”

— Miles Reid, **Problems on pencils of small genus**, (1990).

I’m just saying. The photographic games we play here at Utata can sometimes seem a little fanciful, a little absurd, divorced from reality. But if this right here isn’t proof that we’ve got our feet planted firmly on the ground? That Iron Photographer is downright *scientific*? Well. I don’t know what is.
