Magic: The Gathering Mana Curve Analysis
Magic: The Gathering came out of mathematician Richard Garfield's work and was published by Wizards of the Coast in 1993, making it the first modern collectible card game. Every card carries a Converted Mana Cost (CMC), the total mana you need to cast it, and the “mana curve” is just how those CMC values are spread across a deck. When the curve is balanced, you tend to have a worthwhile spell to play on each turn starting early.
A Standard deck usually runs 60 cards, and a common split is roughly 24 lands + 16 ramp/utility + 20 creatures/spells. To read the curve you bucket the cards at CMC 1, 2, 3, 4, 5+. Aggro decks pile onto 1–2 CMC for a low bell curve. Midrange sits around 3–4 CMC. Control runs heavier, keeping its answers and finishers in the 5–7 range.
Applications
Competitive players, deck builders, and content creators all lean on curve analysis to gauge a deck's consistency before a tournament. Statistician Frank Karsten has written widely cited pieces on ideal land counts and curve shapes per archetype, using hypergeometric probability to work out the odds of drawing what you need on a given turn.
FAQ
How many lands should I run? Frank Karsten’s tables point to roughly 17 lands when your average CMC is near 2.0, 23–24 around 3.0, and 26+ for control builds carrying heavier top-end spells.
Does ramp affect the curve? It does. Ramp spells like Llanowar Elves get your higher-CMC cards out a turn early, which in practice slides the playable curve down by one.
Why is 4 CMC often the ceiling? In aggro and midrange, hardly any game drags past turn 6 without a result, so anything above 4 CMC has to earn its slot as a finisher rather than filler.

Railway Curve Maximum Speed
Calculate the maximum allowable speed on a railway curve, V = √(127·R·(h_a + I) ÷ B), from the curve radius R (m), the applied cant h_a (mm), the allowable cant deficiency I (mm) and the gauge B (mm). It is the inverse of curve design: given an existing curve (radius and cant) and the permitted deficiency, it finds the maximum speed trains can run safely and comfortably. Speed is limited because above it the cant deficiency would exceed the allowable — passengers would feel excessive lateral force and wheel-rail wear and risk would rise. This is fundamental in railway operation: it defines each section's maximum speeds (line speed profile) and travel time. Raising speed on existing curves needs more cant (limited), more allowed deficiency (tilting trains) or, ultimately, larger-radius regrading — an expensive work. Enter the radius, applied cant, allowable deficiency and gauge.
DC Motor No-Load Speed
Calculate the no-load speed of a DC motor, ω = V ÷ K_e, from the applied voltage V and the back-EMF constant K_e (V·s/rad). The result, in rad/s, is the speed the motor reaches with no load, when the generated back-EMF nearly equals the applied voltage and the current drops to a minimum. It is the upper speed limit of the motor for a given voltage, the basis of the torque-speed curve (running from stall torque at zero speed to no-load speed at zero torque). It lets you estimate the operating range of servos and DC motors. Enter the voltage and the constant K_e.
Railway Cant (Superelevation)
Calculate the theoretical equilibrium cant (superelevation) of a railway curve, h = (B·V²) ÷ (127·R), from the dynamic gauge B (mm, distance between rail centers, ~1500 mm on standard gauge), the speed V (km/h) and the curve radius R (m). Cant is the raising of the outer rail above the inner one in curves, tilting the track inward — so the train's weight component helps provide centripetal force, balancing the centrifugal acceleration felt by passengers and reducing wheel-rail lateral wear. Equilibrium cant fully cancels the unbalanced lateral acceleration for a given speed; in practice a lower cant is adopted, since trains run at varied speeds on the same curve, and construction limits (~150-160 mm) apply for comfort and overturning safety of stopped trains. The difference between equilibrium and applied cant is the cant deficiency (or excess). Enter the gauge, speed and curve radius.
Bootstrap the Zero Curve
Builds the zero (spot) rate curve from par rates using sequential bootstrapping: at each maturity it uses the par-bond identity to strip out the discount factor and converts it to the annual zero rate. This is the step that turns observed market rates into the discount curve used to price any cashflow. Enter the list of annual par rates; the output is the zero rate at each maturity.
