The Aharonov-Bohm effect. One of those “quantum trumps classical electromagnetics” items.
Also an Erdős–Bacon number, which fits this thread.
Wentzel–Kramers–Brillouin
Hartree–Fock
Speaking of theories of gravity, Kaluza-Klein is a model of electromagnetism based on curved space like gravity, and a conceptual ancestor of the string models.
markn+, how the heck do you produce that character, then?
EDIT: And of course, that character was invented by Lawrence Acute and Mordecai Double, at the University of Budapest.
There are hundreds and hundreds of medical examples.
Here are a few I can think of:
**Wolff-Parkinson-White syndrome **(something to do with cardiac rhythm)
Sturge-Weber sydrome (something neurological, seizures)
Guillain-Barre syndrome (autoimmune disease involving nervous system)
mmm
Myers–Briggs
The Wesley Willis Fiasco.
Heckscher–Ohlin model for economics
The Unicode value is U+0151 (or U+0150 for upper case). How you actually enter it depends on what OS you’re using. Sometimes there’s a key sequence to enter the Unicode value directly. Or you can do what I do, just find it somewhere, like in the wiki article, and copy/paste it.
Don’t forget the Roth-Stone and Kaplan-Sheinwold Systems of bidding for contract bridge. They introduced important conventions like Weak Twos, Negative Doubles, Weak No Trump.
Obviously there are still dozens of important math theorems not yet mentioned. I’ll just throw in three famous paradoxes — Banach-Tarski Paradox, Borel-Kolmogorov Paradox, Cramer-Euler Paradox — and an Identity named after two ancients: the Brahmagupta-Fibonacci Identity.
Don’t forget Maxwell-Boltzmann statistics, presented first and IIUC still useful as an approximation to both B-E and F-D statistics at highish temperatures and lowish densities.
Saffir-Simpson scale for hurricane strength.
How about the Gell-Mann-Okubo mass formula, which looks like it shouldn’t meet the criteria in the OP but does.
The Darwin-Wallace Theory of Evolution by Natural Selection, although Wallace is often left out.
In ecology, there’s the Janzen-Connell hypothesis about what maintains species diversity in tropical forests and coral reefs.
There are loads of them in math. Here’s a few.
Stone-Weierstrass theorem.
Stone-Cech compactification.
Yank-Mills equation.
Eilenberg-Steenrod axioms for homology.
Eilenberg-Mac Lane cohomology.
Zermelo-Frankel axioms for set theory.
I could go on–but won’t.
Technically they’re not hyphens but en dashes, which are used for noun–noun compounds in English. (For some reason, the SDMB replaces en dashes with hyphens when viewing a thread, which sets off my typographical OCD something fierce.)
Runge-Kutta methods in numerical analysis, which most people with STEM degrees were probably exposed to in college.
Cooley-Tukey algorithm - the first modern FFT algorithm and basis for a vast amount of modern computation.
The Parks-McClellan algorithm for designing finite impulse response filters - though both Parks and McClellan instead preferred calling it a variation of the Remez exchange algorithm, which is how it is documented in Matlab.
Haber-Bosch process for making ammonia (often shortened to just the Haber process). And that page provided two more:
Frank-Caro process for making calcium cyanamide.
Birkeland-Eyde process for making nitric acid.
